Foundation readies 25 computer to seed tech talents

first_img Raspberry Pi wants to inspire young people to start technology careers. User-focused lessons on how to write letters or enter data on Excel spreadsheets may be fine but the devices will place students on a learning and discovery track closer to computer science than end-user skills. The students would receive these credit-card sized computers and courses would be structured around their use. A posting on the Raspberry Pi blog this week revealed the announcement that the computers are almost ready, seen as good news by many who have been watching for progress updates. The posting said the first finished circuit boards had arrived and that test versions are to be put through electrical, software and hardware testing. If all goes well, volume production will kick in and orders for the computers will also be taken early next month.This week’s arrival of the circuit boards is treated as a milestone, as the bare bones circuit boards are the first to be populated with all the components to go into the finished product. Mice, keyboards, network adapters and external storage connect via USB hub. The computer can be plugged into a TV or monitor and keyboard. Explore further This document is subject to copyright.

Tray madness Scientists score wireless data record

first_img Explore further Japan collab transmits record data speeds on terahertz waves More information: Direct intensity modulation and wireless data transmission characteristics of terahertz-oscillating resonant tunnelling diodes, Electron. Lett. — 10 May 2012 — Volume 48, Issue 10, p.582–583. intensity modulation and wireless data transmission characteristics of terahertz-oscillating resonant tunnelling diodes (RTDs) is reported. A direct intensity modulation of the RTD oscillators was demonstrated, and the frequency response was measured. It was found that the 3 dB cutoff modulation frequency was limited by the parasitic elements of the external circuit, and increased up to 4.5 GHz by reducing such parasitic elements. Wireless data transmission by direct amplitude shift keying was demonstrated using an RTD oscillating at 542 GHz with cutoff frequency of 1.1 GHz. The BERs for bit rates of 2 and 3 Gbit/s were found to be 2×10−8 and 3×10−5, respectively. Citation: T-ray madness: Scientists score wireless data record (2012, May 16) retrieved 18 August 2019 from Their breaking through the 3Gbps barrier is seen as enticing news for a future where broadband users can get impressively high data rates and broadband speeds The terahertz, or “T-ray,” region is part of the electromagnetic spectrum between 300 GHz and 3 THz. Research sites performing imaging make use of terahertz because it is a less damaging alternative to x-rays, in that terahertz waves can penetrate materials but deposit less energy. Outside such settings, where heavy and costly machines are at work, the spectrum has not been considered as a practical solution for daily use. The researchers’ work may make such considerations plausible. The team developed specialized hardware that was capable of achieving the 3Gb data transmission. They made use of resonant tunneling diode, which produces smaller voltages with increasing current, i.e., the voltage decreased as the current increased. “By tuning the current, the team could make the device resonate and spit out signals in the terahertz band,”as Gizmodo commented.Findings of the T-ray researchers, who are from the Tokyo Institute of Technology, have been, published in Electronics Letters. The study suggests that Wi-Fi using the system may support data transmission rates of up to 100 Gbit/s. The researchers note that terahertz Wi-Fi, however, would probably only work for ranges up to 10 meters, but data transmission within that range would be orders of magnitude higher than current alternatives. Their research is still a work in progress, and they intend to extend the range.Beyond their research, Wi-Fi watchers expect favorable progress to come from the new standard 802.11ac, which is said to be the next evolutionary stage of wireless networking.

Planes trains and molecules Deriving a generic routing algorithm from the physics

first_img Changes in optimized traffic in the central London subway network after the removal of the station “Bank” (black node). The corresponding costs are γ= 2 (A) and γ= 0.5 (B). Nodes and edges that show an increase (decrease) in traffic appear in red (blue), where their size and thickness correspond to the magnitude of increase (decrease). Nodes and edges with no traffic changes appear in white and black, respectively. Passenger source–destination pairs are identical to those of Fig. 3 [cf. paper], except for the removal of pairs starting or ending destinations in Bank. Copyright © PNAS, doi:10.1073/pnas.1301111110 Finding a single optimal route is easy, but optimizing the combination of multiple routes is a challenge found in a wide range of applications including Internet instant messaging, peer-to-peer networks, subway traffic, airport flight management, water distribution systems, sensor deployment, military convoy logistics, and trip planning. Historically, due to the computational complexity of deriving a global path optimization (that is, one that simultaneously considers all path possibilities), existing routing algorithms typically optimize each paths in isolation. As a consequence, the resulting solutions are less than optimal. Recently, however, scientists at Aston University, United Kingdom and The Hong Kong University of Science and Technology used the physics of interacting polymers (large molecule composed of many repeated subunits, known as monomers) and disordered systems to analyze macroscopic properties of generic path optimization problems. By so doing, they derived a simple yet global, routing algorithm capable of simultaneously considering all individual path alternatives. The researchers then demonstrated the algorithm utility by applying it to Internet-like random graphs, travel on the London Underground, and the global airport network. Moreover, their analysis revealed phase transitions, scaling laws, non-monotonic growth (that is, not always stable or increasing), and other new routing phenomena related to physics. Explore further © 2013 All rights reserved. Removing ‘black sheep’ could make Internet run more efficiently Research Fellow Chi Ho Yeung discussed the research he and his colleagues, Profs. David Saad and K. Y. Michael Wong, conducted – and the challenges they face – with “While, employing tools in physics to solve the system analytically was indeed our most difficult task,” Yeung tells, “the analogy between polymers and paths is actually easy to understand. A polymer is a long molecule chain likes a string with two ends,” he illustrates, “Suppose I represent my travel path by a polymer: the two ends will be fixed representations of my starting point and destination, and the polymer body will be flexible depending on my path choice. If every traveler represents their path this way, we’d have a system of polymers on a transportation network – meaning that to suppress congestion, we’d introduce a repulsive force between polymers to discourage users using the same route. On the other hand, to encourage passengers share their path we’d introduce an attraction.”Turning now to their analytic work, Yeung points out that polymer paths are non-local variables, which are more difficult to analyze compared to local variables and interactions in conventional physics models. In addition, he notes that all polymers share the same network infrastructure and any two of them may have overlapping paths. “In our transportation network, when polymers overlap they either interact through an attraction or repulsion. It is thus equivalent to say that any two polymers may interact,” Yeung continues, “and the extent of that interaction depends on the extent of overlap, which is again a non-local consideration regarding all polymers. With all these complications, we had to select the best paths out of all possible individual choices as well as their mutual overlapping.” Compared to ordinary polymer systems (which do not allow overlap), they researchers had a much larger pool of possible states, and thereby a much more difficult question to solve. “After deriving our theoretical results,” Yeung adds, “we obtained the algorithm directly – and testing it on several datasets, found very good results. Once the system was analytically solved, it was straightforward to find its macroscopic properties, such as average path length and energy, by ordinary physics techniques in our area.” One key insight the scientists had, says Yeung, was that while some may think that the shortest path is always the best choice, this is not the case – and in fact, usual choice of going through the shortest path is a bad one when everyone takes the same route. “This isn’t difficult to understand, as some observers may have already noticed. For example,” Yeung illustrates, “during peak hours, some popular routes which lie on the shortest path may be overloaded, causing delays and making this path slower than a slightly longer one.” Yeung points out that their simulations with the London metro data show that – compared to when all passengers travel through the shortest path – if they introduce a repulsive force between passenger paths, and if passengers follow the suggested path, 20% of the assumed cost can be saved at a price of only 6% increase in average path length. “On the other hand,” Yeung continues, “although congestion does not occur in off-peak hours, the shortest path is still a bad choice, because the whole network has to remain active even for reduced usage on the less popular routes. Suppose we encourage off-peak commuters to travel on some common routes and share a large part of their journeys; then, the less popular bus routes or train lines can be discontinued which saves a lot of energy.” Yeung adds that their results show that they can obtain such optimized shared path configurations through the analogy to an attractive polymer system.Other than these results, the scientists also found that when they gradually change the polymer interaction from slightly repulsive to slightly attractive, there is a sharp increase in the number of idle nodes. “This is similar to a discontinuous phase transition observed in other physical systems,” Yeung says. “Surprisingly, while the average path length does not change much, it does have an important implication on transportation or communication networks – that is, one can greatly increase the number of idle nodes without significantly lengthening the average path length, by introducing a slight attractive force between passenger paths. This may save a lot of resources in sparse traffic scenarios.”A key aspect of the researchers’ results was demonstrating the algorithm’s efficacy by applying it to random graphs resembling Internet overlay networks – that is, computer networks built on top of another network, in which nodes can be thought of as being connected by virtual or logical links, each of which corresponds to a path, perhaps through many physical links, in the underlying network. “Networks representing websites interconnected by hyperlinks, or friends linked by instant messengers, are usually not bounded by physical location,” Yeung notes, “and are well described by some specific random structures. We show in a simple random network how we can find the best choice of communication paths according to the attractive or repulsive strength we introduced.”In the case of repulsion, Yeung explains, individual communication paths avoid each other and at last almost everyone has its own path not overlapping with the others. In the case of attraction, the communications go through a small common region of the network, sharing their paths and leaving a lot of other nodes and links idle. “If we consider the idle nodes as routers,” he points out, “a lot of energy can be saved by switching them off.”The researchers also applied their findings to travel on the London Underground network based on Oyster card data. “If we compare to the case where everyone takes their shortest path,” says Yeung, “our simulations show substantial improvement on the London Metro network. Again, at a price of only 6% increase in average path length, 20% and 4% of the assumed cost are saved on the London metro network when one aims to balance or consolidate traffic, respectively. Of course, in practice,” he acknowledges, “some experienced users would adopt a smarter route than the shortest path and the benefit from our algorithm would be less. However, I believe that in many transportation or communication networks there is still a large room of improvement in terms of energy saving if individual paths are well coordinated.” Yeung adds that they did a very similar experiment, and obtain a similar result, in the global airport network.Regarding other innovations that the scientists might develop and apply to the current experimental design, Yeung says that since physicists usually start with a generic model of physical systems, they’ve also assumed a model of interacting polymers which accommodates different type of interaction. “It turns out that we obtain a single algorithm which achieves various goals by tuning a single parameter controlling the attractive and repulsive strength between polymers,” he explains. “Indeed, our approach can take into account interactions other than attraction and repulsion, and which may have other interesting applications. We welcome networking experts to suggest other specific routing problems which our algorithm may be able to tackle.On the practical side, Yeung continues, one idea may be to develop a real-time application, based on their algorithm, to globally coordinate paths for individuals who start their journey at roughly the same time. “It’s not the same as the usual route-finder applications that simply identify the shortest path for individuals without their interactions with others,” he explains. “Rather, the envisioned application would coordinate routes for many individuals who travel at the same time in order to achieve goals like balancing highway or tunnel usage, or to encourage train or plane sharing in off-peak hours or seasons.”Yeung also describes the planned next steps in their research. “Our path solution is static.” He notes. “In other words, it provides an optimized path configuration given a set of destination pairs, and so suits many applications – but not those where the amount of traffic between individual destination pairs is rapidly changing. The next step is, perhaps, to develop routing algorithms based on our framework which address a dynamical routing task.”Yeung notes that other areas of research that might benefit from their study. “Our generic routing algorithm is applicable to any application that involves the path selection and coordination of individual paths,” he tells “I hope our work can contribute to routing problems in transportation and communication networks, as well as sustainability research where the fixed infrastructure of existing transportation or communication systems is better utilized, thereby reducing the needs for further construction. In a more general respect,” Yeung concludes, “I hope that our work demonstrates the power of rigorous physical tools when applied to interdisciplinary areas outside the realm of physics.” More information: From the physics of interacting polymers to optimizing routes on the London Underground, PNAS Published online before print July 29, 2013, doi:10.1073/pnas.1301111110 Optimized traffic on the London subway network.

Credit: arXiv:1501.01881 [cond-mat.mes-hall] For several years, material scientists, chemists, physicists and others researchers have been excitedly working to find a way to create graphene in bulk and to force it to have a band gap. Thus far, that work has not led to a breakthrough that would allow the so-called miracle material to be used for much in the way of real world applications. In this new effort, the research team has moved their focus to black phosphorus (aka phosphorene) which has many of the same beneficial traits as graphene, but currently has, at least theoretically, a way to induce a band gap. Up till now, however, making black phosphorus was done the same way as making graphene, e.g. using sticky tape to pull layers off a bulk sample—that is obviously not a good way to produce material suitable for commercial applications. Now it appears the team in Ireland has found another way—one that is simple, inexpensive and allows for separating out different sized sheets.To get sheets of black phosphorus the team created a block of it first, then, instead of trying to rip layers off with tape, they submerged it in a CHP liquid solvent and then piped in acoustic waves, which served to knock off layers of phosphorene (nanosheets) into the solution. The team then filtered the sheets using a centrifuge. Using this method the team reports that they have been able to produce nanosheets of black phosphorus in bulk, some of which are just a few layers thick.The researchers have used the results of their efforts to test the usefulness of using black phosphorus in a variety of applications, ranging from increasing the strength of polyvinyl chloride, to an ammonia detector. They note the nanosheets do suffer from one serious drawback—they tend to disintegrate over a short period of time when exposed to water or oxygen, but the team is optimistic that solvents can be created to provide a protective shell around the sheets that will still allow it to perform its useful functions.

We can control nanosheet dimensions and have developed metrics to estimate both nanosheet size and thickness spectroscopically.

Computational studies show the degradation to occur by reaction with water molecules only at the nanosheet edge, leading to the removal of phosphorus atoms and the formation of phosphine and phosphorous acid.

New study shows why hemecopper oxidases prefer copper over iron

first_img More information: Ambika Bhagi-Damodaran et al. Why copper is preferred over iron for oxygen activation and reduction in haem-copper oxidases, Nature Chemistry (2016). DOI: 10.1038/nchem.2643AbstractHaem–copper oxidase (HCO) catalyses the natural reduction of oxygen to water using a haem-copper centre. Despite decades of research on HCOs, the role of non-haem metal and the reason for nature’s choice of copper over other metals such as iron remains unclear. Here, we use a biosynthetic model of HCO in myoglobin that selectively binds different non-haem metals to demonstrate 30-fold and 11-fold enhancements in the oxidase activity of Cu- and Fe-bound HCO mimics, respectively, as compared with Zn-bound mimics. Detailed electrochemical, kinetic and vibrational spectroscopic studies, in tandem with theoretical density functional theory calculations, demonstrate that the non-haem metal not only donates electrons to oxygen but also activates it for efficient O–O bond cleavage. Furthermore, the higher redox potential of copper and the enhanced weakening of the O–O bond from the higher electron density in the d orbital of copper are central to its higher oxidase activity over iron. This work resolves a long-standing question in bioenergetics, and renders a chemical–biological basis for the design of future oxygen-reduction catalysts. (—A family of enzymes known as heme-copper oxidases (HCOs) plays a pivotal role in the reduction of oxygen into water during cellular respiration. One mystery surrounding heme-copper oxidases is why the non-heme metal center tends to be copper rather than iron. Structure of an enzyme that pathogenic bacteria use to reduce oxygen revealed Explore further Credit: Bhagi-Damodaran, et al Journal information: Nature Chemistry A group of researchers from the University of Illinois, Stevens Institute of Technology, and Oregon Health & Science University has developed a biosynthetic protein model system that replicates the active sites and many structural features of naturally-occurring HCOs. With their model system, they looked at the differences in the reduction of oxygen to water when the non-heme metal is iron versus when it is copper. They found that the non-heme metal plays a key role in electron donation and O-O bond cleavage and that it is likely copper’s d-orbital electron configuration that causes its enhanced activity. Their work appears in Nature Chemistry.”HCOs have been studied for more than half a decade now, but the selection of copper by nature at the nonheme center over other metal ions was not understood,” says lead author Dr. Ambika Bhagi-Damodaran. “Our work is exciting because we finally resolve this long-standing question regarding the structure and function of this very important respiratory enzyme.” Their synthetic analog to the natural heme-copper oxidase is made from myoglobin, a small protein found in muscle that is a cousin to hemoglobin. Myoglobin has an iron-containing heme center and is denoted as FeBMb(FeII) because the heme iron is in the 2+ oxidation state. FeBMb(FeII) was produced and purified without a metal in the non-heme site using a previously reported procedure.The empty FeBMb(FeII) was titrated with ZnII, which is not redox active and serves as the experimental control, CuI, and FeII. Ultraviolet-visible spectroscopy confirmed that each metal was incorporated into the non-heme site. X-ray crystallography confirmed that each of these metal-FeBMb(FeII) variants exhibited similar active sites. In other words, this confirmed that the identity of the non-heme metal did not induce structural changes.Bhagi-Damodaran et al. then investigated the differences in catalytic activity between the iron- and copper-containing species. They looked at reaction rate as well as product selectivity. Their enzymatic assay showed that FeII-FeBMb(FeII) and CuI-FeBMb(FeII) had 11-fold and 30-fold higher oxidase activity compared to the ZnII control and the FeBMb(FeII) without a non-heme metal. This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. Using electron paramagnetic resonance and X-ray near-edge spectroscopy, they determined that the non-heme CuI was oxidized to CuII and the non-heme FeII was oxidized to FeII, thus confirming that the non-heme metal plays a central role in oxygen reduction as electron donors. To further understand the difference between copper and iron, Bhagi-Damodaran et al. studied the standard reduction potentials (Eo’) of FeIII/FeII and CuII/CuI at the model enzyme site. (The heme iron was replaced with a redox-inactive zinc protoporphyrin using a previously reported protocol.)They found in both species a single reversible wave that corresponded to Eo’ of 259 ± 20mV for iron and Eo’ of 387 ± 25mV for copper. Since standard reduction potentials are related to the thermodynamic driving force of a reaction, copper’s higher value means that CuII/CuI is more efficient at receiving electrons for the electrochemical reduction of oxygen to water.The last step was to look at whether non-heme iron or copper interacts with heme-bound O2 to aid in cleaving the O-O bond. Using resonance Raman spectroscopy, the authors looked at the vibration of the O-O bond and found that the terminal oxygen atom interacts with the nonheme metal weakening the O-O bond. To test if the identity of the nonheme metal had any impact on O-O bond length, the authors performed Density Functional Theory calculations and found that O-O bond length was longest in CuI-FeBMb(FeII). These results showed that the non-heme metal plays an important role in activating the oxygen molecule and facilitating O-O cleavage. The preference of HCOs for copper is likely due to the higher redox potential of Cu as well as its d-orbital electron configuration. Copper-II has nine d-electrons, while FeIII has five d-electrons. This additional electron density gives copper the advantage in orbital interactions with oxygen’s highest occupied molecular orbitals.Overall, this work provides important insights into naturally-occurring heme-copper complexes. According to corresponding author Professor Yi Lu, “We anticipate our work to be a starting point for more focused efforts toward using different metal ions at the non-heme site for various biochemical reactions. This pursuit can aid the design of novel catalysts required in alternative energy technologies and other biotechnological applications.” Citation: New study shows why heme-copper oxidases prefer copper over iron (2016, November 24) retrieved 18 August 2019 from © 2016 Phys.orglast_img read more

Eating citrus fruits may increase melanoma risk

first_imgFrequent consumption of citrus fruits like whole grapefruit and orange juice may be associated with an increased risk of melanoma, a type of skin cancer, says a large study.Analysing dietary patterns among more than 100,000 people in the US, the researchers found that melanoma risk was 36 per cent higher in people who consumed citrus fruit or juice at least 1.6 times daily compared to those who consumed them less than twice per week.

Over a follow-up period of up to 26 years, 1,840 study participants were diagnosed with melanoma.  Higher overall citrus fruit consumption (the total number of servings of whole grapefruit, whole oranges, and juices from those fruits) was associated with increased risk of malignant melanoma in both men and women. The association was strongest for grapefruit, followed by orange juice. The study was published online in the Journal of Clinical Oncology.last_img read more

Organic guide to save yourself from harsh Holi colours

first_imgNew Delhi: Holi, the festival of colours, is fun as we paint the town in hues of the rainbow. But, at the same time, your hair, skin and eyes have to brave the chemicals those pretty colours contain. Experts suggest that a pre-and post-Holi regime can be a boon and save you from allergies if followed properly. To start with pre-care, you cannot afford to ignore your ear lobes and nails. Preeti Seth, cosmetologist at Pachouli Wellness Clinic, and dermatologist Aparna Santhanam suggest applying oil in and around your ear lobes and placing a small ball of cotton into your ears before you go out to play so that your inner ear is well protected. Also Read – Add new books to your shelfSeth said: “Always clip your nails because there is no way that you can protect your nails if they are long; and apply a dark nail paint to protect your nails. Colours will come off easily when you remove nail polish.” To prevent colours from clogging the pores, Seth says it’s best to avoid shaving 2-3 days before.Jyotsana Makkar, in-house ayurvedic doctor for Kama Ayurveda, suggests application of almond oil on your face and other exposed parts of body and hair – and braid your hair if possible. Also Read – Over 2 hours screen time daily will make your kids impulsive”Besides being a nourishment agent with high levels of vitamin E, almond oil also forms a protective layer on your skin and hair and saves you from the damage of chemical colour,” says Makkar. Amit Karkhanis, medical cosmetologist at Dr. Tvacha Clinic, says using coconut oil on your entire body before you step out to play Holi will act as a moisturiser and an anti-inflammatory, and prevent sun damage. A common suggestion by all the experts is that a good sunscreen, with an SPF factor of at least 40, is a must-do, just half an hour before leaving the house. “Expecting mothers can opt for a pomegranate or jojoba oil as these natural oils are safe to use on the face and protect pores,” says Shubhika Jain from RAS Luxury Oils. Do not neglect your hair on the occasion, which somehow many forget about and then repent. One must do deep champi (massage) in the days preceding Holi to prepare the hair and scalp for the festival,” added Jain. Dermatologist Rashmi Shetty suggests different tips for different kinds of hair textures.”For straight hair, apply a new age coconut oil that has ingredients like jasmine as it known to strengthen the hair and make it less prone to breakage even after too much exposure to colours,” she said. Curly hair needs extra care, so Shetty suggests taking a generous amount of coconut-based oil and applying it to your scalp and the length of your hair before you go out to play.Post-Holi, it is not exactly a cake walk to get rid of the tough colours and its imperative to swipe off the several coatings of oils and sunscreen that were layered onto your hair and skin. Makkar suggests an ubtan soap-free body cleanser which is made up of natural ingredients like turmeric, fenugreek, sandalwood, neem, oatmeal and more.”You will need to shampoo a couple of times to remove all traces of colour. Wash your hair with a very mild shampoo daily to get rid of residual colour and dirt. Follow this with an application of warm oil. This will help restore and rejuvenate your hair, nourishing it back to health,” said Shetty. Seth suggests that if the colour is too harsh, apply lemon wedges to that area as the stains will lighten. Lastly, it may have not occurred to you but your eyes are the most vulnerable when it comes to the effects of Holi. Sameer Kaushal, Senior Consultant Opthalmologist at Tattvan eclinics, says it is crucial to always cover your eyes while playing with colours as they contain toxic substances which may cause irritation, pain, watering in eyes and may even cause blurriness for many days.”last_img read more

Tobacco display bans effective in reducing smoking in children

first_imgRemoving displays of tobacco products from shops may have reduced the proportion of children buying cigarettes by 17 per cent, claimed a new research.The findings, based on the analysis of the impact of the 2015 tobacco display ban in England, revealed that the percentage of children who smoked regularly fell to 40 per cent by 2016, from 57 per cent before. “The research shows that removing displays made tobacco less visible to children, and that fewer of them bought cigarettes there. This research provides evidence that the introduction of display bans will be an effective measure against children smoking – and could help save them from starting a deadly habit,” said Anthony Laverty, lead author of the research from the School of Public Health at Imperial. Also Read – Add new books to your shelfThe study published in the journal Tobacco Control, assessed survey responses from 18,000 11-15 year olds from across England between 2010 and 2016.Among the children who smoked, the most common source of cigarettes was from friends, followed by shops. This remain unchanged between 2010-2016. Interestingly, there was no increase in children reporting they had purchased cigarettes from illegal sources. The proportion of children who said they had bought cigarettes from street markets remained steady at under 10 per cent between 2010 and 2016. Also Read – Over 2 hours screen time daily will make your kids impulsiveOther reasons that may have helped reduce smoking rates, could be such as the ban on cigarette vending machines and higher taxes, Laverty said. However, the researchers found that more than two in three child smokers had not been refused cigarettes when they last attempted to buy them – a figure that remained unchanged between 2010-2016.Furthermore, the majority of child smokers said it was easy to buy cigarettes in shops. This rose slightly from 61 per cent in 2010 to 65 per cent in 2016. While the results are encouraging, more work is needed to ensure effective tobacco control, the researchers said adding that it is still too easy for children to purchase cigarettes in shops. Besides enforcement, government cuts as well as a licensing system for tobacco retailers – similar to that seen for alcohol – needs to be introduced, the researchers suggested.last_img read more

Colin OBJ was right to address the elephant in the room that

first_img Advertisement Odell Beckham made headlines this weekend when he bluntly addressed the poor play of Eli Manning in an ESPN interview. Many have crushed OBJ for publicly commenting on his QB to the media, but Colin thinks he was within his rights to do it.Colin has been critical of Beckham for being a head case throughout his career, but OBJ is also one of the few people in the Giants locker room who has the job security – after signing a massive new deal – to speak his mind without fear of getting cut. In this case, he was just addressing the obvious elephant in the room that is Eli’s poor play. It’s not a secret to anyone who has watched him play in the last five years.Even if the Giants and the New York media continue to treat Eli with kid gloves as his play continues to decline, Odell was right to try to address the most obvious issue with Giants. If some people don’t want to hear the truth, that’s their problem.“There’s a responsibility in football for the handful of players who can say whatever they want and not get demoted to bring up the elephant in the room.”@ColinCowherd defends Odell Beckham Jr. for his comments about Eli Manning— Herd w/Colin Cowherd (@TheHerd) October 8, 2018last_img read more

10 DataSecurity Measures You Cant Do Without

first_img 6 min read November 4, 2010 Brought to you by Business Insider Register Now » Data security should be an important area of concern for every small-business owner. When you consider all the important data you store virtually — from financial records, to customers’ private information — it’s not hard to see why one breach could seriously damage your business.According to the most recent Verizon Data Breach Investigations Report [PDF], an estimated “285 million records were compromised in 2008.” And 74 percent of those incidents were from outside sources.We consulted Roland Cloutier, Chief Security Officer for ADP and a board member for the National Cyber Security Alliance, and Matt Watchinski, Senior Director of the Vulnerability Research Team for cybersecurity provider Sourcefire, to find out the key security measures every small business should be taking.1. Establish strong passwordsImplementing strong passwords is the easiest thing you can do to strengthen your security.Cloutier shares his tip for crafting a hard-to-crack password: use a combination of capital and lower-case letters, numbers and symbols and make it 8 to 12 characters long.According to Microsoft, you should definitely avoid using: any personal data (such as your birthdate), common words spelled backwards and sequences of characters or numbers, or those that are close together on the keyboard.Use their convenient password checker to see how strong yours is.As for how often you should change your password, Cloutier says that the industry standard is “every 90 days,” but don’t hesitate to do it more frequently if your data is highly-sensitive.Another key: make sure every individual has their own username and password for any login system, from desktops to your CMS. “Never just use one shared password,” says Cloutier.And finally, “Never write it down!” he adds.2. Put up a strong firewallIn order to have a properly protected network, “firewalls are a must,” Cloutier says.A firewall protects your network by controlling internet traffic coming into and flowing out of your business. They’re pretty standard across the board — Cloutier recommends any of the major brands.3. Install antivirus protectionAntivirus and anti-malware software are essentials in your arsenal of online security weapons, as well.”They’re the last line of defense” should an unwanted attack get through to your network, Cloutier explains.4. Update your programs regularlyMaking sure your computer is “properly patched and updated” is a necessary step towards being fully protected; there’s little point in installing all this great software if you’re not going to maintain it right.”Your security applications are only as good as their most recent update,” Watchinski explains. “While applications are not 100 percent fool-proof, it is important to regularly update these tools to help keep your users safe.”Frequently updating your programs keeps you up-to-date on any recent issues or holes that programmers have fixed.5. Secure your laptopsBecause of their portable nature, laptops are at a higher risk of being lost or stolen than average company desktops. It’s important to take some extra steps to make certain your sensitive data is protected.Cloutier mandates “absolutely: encrypt your laptop. It’s the easiest thing to do.”Encryption software changes the way information looks on the harddrive so that, without the correct password, it can’t be read.Cloutier also stresses the importance of never, ever leaving your laptop in your car, where it’s an easy target for thieves. If you must, lock it in your trunk.6. Secure your mobile phonesCloutier points out that smartphones hold so much data these days that you should consider them almost as valuable as company computers — and they’re much more easily lost or stolen. As such, securing them is another must.The must-haves for mobile phones:Encryption softwarePassword-protection (Cloutier also suggests enabling a specific “lock-out” period, wherein after a short amount of time not being used, the phone locks itself)Remote wiping enabledRemote wiping is “extremely effective,” Cloutier says, recounting the story of one executive who lost his Blackberry in an airport, after he had been looking at the company’s quarter financials. The exec called IT in a panic, and within 15 minutes they were able to completely wipe the phone.7. Backup regularlyScheduling regular backups to an external hard drive, or in the cloud, is a painless way to ensure that all your data is stored safely.The general rule of thumb for backups: servers should have a complete backup weekly, and incremental backups every night; personal computers should also be backed up completely every week, but you can do incremental backups every few days if you like (“however long you could live without your data,” Cloutier explains).Getting your data compromised is a painful experience — having it all backed up so you don’t completely lose it will make it much less so.8. Monitor diligently”All this great technology […] is no good unless you actually use it. You have to have someone be accountable for it,” says Cloutier.One good monitoring tool Cloutier suggests is data-leakage prevention software, which is set up at key network touchpoints to look for specific information coming out of your internal network. It can be configured to look for credit card numbers, pieces of code, or any bits of information relevant to your business that would indicate a breach.If you don’t monitor things, warns Cloutier, “it’s a waste of time and a waste of resources.” And you won’t know that you’ve been compromised until it’s far too late.9. Be careful with e-mail, IM and surfing the WebIt’s not uncommon for a unsuspecting employee to click on a link or download an attachment that they believe is harmless — only to discover they’ve been infected with a nasty virus, or worse.”Links are the numbers one way that malware ends up on computers,” says Cloutier. “Links are bad!”As such, never click on a link that you weren’t expecting or you don’t know the origination of in an e-mail or IM.You have to “be smart when surfing the Web,” Watchinski warns. “[You] should take every “warning box” that appears on [your] screen seriously and understand that every new piece of software comes with its own set of security vulnerabilities.”10. Educate your employeesTeaching your employees about safe online habits and proactive defense is crucial.”Educating them about what they are doing and why it is dangerous is a more effective strategy than expecting your IT security staff to constantly react to end users’ bad decisions,” Watchinski says.It’s not easy: “One of the most difficult things to do is protect end users against themselves,” he adds. But ultimately, prevention is the best approach to handling your data security.Make sure your employees understand how important your company’s data is, and all the measures they can take to protect it.

Computers in Your Underwear Where Wearable Tech Must Go to Succeed

first_imgMarch 11, 2014 4 min read While it’s common to see Google Glass at events such as SXSW, wearable technology is still on the fringe for many. A SXSW panel Monday titled “Tech Off Your Clothes: Naked Truths of Wearables,” explored this issue with a trio of experts sharing their insights, moderated by Nicole Forbes, a senior consultant at Violet Crown Consulting. The thought leaders included Q Manning, the chief executive officer of design firm Rocksauce Studios, Jay Morgan of HAVAS world Wide and Billie Whitehouse, the mad genius behind Fundawear, a line of undergarments that lets couples…stimulate each other from afar. In the hour-long discussion, the group chatted about what’s wrong with modern wearables, the secrets to a great product and where they think this industry is headed.Make it look good. Every panelist agreed: Google Glass is not the future of wearable tech. “When Google Glass is embedded into Tom Ford sunglasses, we’ll wear it,” Whitehouse says. The panel agreed that the best wearable tech doesn’t look like wearable tech at all — it just looks like part of your wardrobe.Morgan says that wearable tech will truly arrive when you can’t tell the difference between tech-enhanced jeans and a regular pair. “I don’t want to think about wearable tech while I’m wearing it,” he says. Whitehouse concurred: “We need to reduce everything down. Give it simplicity.”  But like any fashion line, you’ve got to know your audience. “Design for the market you like,” Manning says, “Everyone has different tastes.During the panel, two models took that stage to show off Fundawear. Morgan asked the audience if they could tell they were wearing a computer. They could not.Solve a problem. Whitehouse sees wearables as a way to escape our phone addiction. “We need to live our lives,” she says, suggesting that wearables will give us the benefits of smart devices without a distracting screen. She modeled a prototype of her line’s “Navigate” jacket which uses GPS technology that “bumps” your shoulder to indicate where to go. Morgan added that the wearable tech of the future won’t require active engagement; it will function as an invisible sixth sense.Currently, they say, the only popular wearables that act subtly are fitness bands and that’s already a crowded market. To stand apart, Manning emphasized that new wearables must solve a new problem. A breakthrough device has to do something that is impossible for your body or mind to do on its own. Innovators will need to ask themselves: “Will this help me live my day-to-day life better?” he asked.Collaboration is key.  “Tech companies should be buying textile companies.” says Manning, adding that a convergence of technology developers and fashion companies is vital to the future of wearables.Whitehouse’s background in textile manufacturing did not prepare her for the difficulty of integrating clothing and software. Since tech companies know little about the fashion industry (and vice versa), she cautioned against companies pursuing vertical integration: “Collaboration is better. Companies need to help each other out.”Smaller software developers will have a rougher road ahead. Manning says that software creators have no easy access to the resources needed to build prototypes. Companies that specialize in creating physical hardware for wearable software will be in demand in the coming years.Wearables need a Steve Jobs. “My mom doesn’t even know that wearable tech exists,” Manning says. If wearables are going to break out, they need a game-changer. “There were smartphones before the iPhone, but we don’t remember them,” he continued. “It’s about creating a killer product that gets people to stand up and say they have to have it.”Whitehouse is sure that the iPhone of the wearable world will come from a new generation of entrepreneurs who enter the industry already integrating fashion and technology. These are the people who will design clothes while accounting for the weight of a battery and will build clothes hangers that charge your smart coat. There will be a community of wearable designers and technologists building their industry from the ground up.Morgan is confident that people will catch on. “People didn’t give a shit about the iPhone until they had it in their hands,” he says. “When wearable tech is just in your clothes, it’ll just be a part of your life.

Celebrate With a Slice Crypto Geeks Its Bitcoin Pizza Day

first_img Free Webinar | Sept. 9: The Entrepreneur’s Playbook for Going Global 3 min read May 21, 2014 Register Now »center_img Growing a business sometimes requires thinking outside the box. Grab a slice, Bitcoin lovers. It’s that time of year again. Time to celebrate Bitcoin Pizza Day!  Delivery or DiGiorno? Nah, make it Papa John’s. It seems more fitting for this particular celebration. Let’s all raise a slice to Jacksonville, Fla., software programmer Laszlo Hanyecz.Four years ago today, Hanyecz laid claim to the ultimate crypto-nerd first. The early Bitcoin adopter forked over 10,000 bitcoins that he mined on his computer for about $25 worth of Papa John’s pizzas. Two hot, scrumptious pizza pies, to be exact.Internet legend has it that it was the first time anyone ever purchased anything using Bitcoin. And it was pizza. Go figure.Related: Nerds Rejoice. Google Glass and Bitcoin, Together at Last.That was back on May 22, 2010, when Bitcoin wasn’t worth jack — not a fraction (0.003) of a penny — not even as much as the gooey good cheese that topped the now legendary pizzas.With the price of a single BTC nearing $490 today, those same pies would cost upwards of $5 million worth of Bitcoin today. Yeah, we know Papa John’s promises “Better Ingredients. Better Pizza.” But, come on. It’s not that special.Naturally, the first thing Hanyecz did after ordering it was brag about it on BitcoinTalk, an early and still-popular Bitcoin discussion forum, even posting a mouthwatering pic of the pizzas for proof. “It wasn’t like Bitcoins had any value back then, so the idea of trading them for a pizza was incredibly cool,” Hanyecz later told The New York Times tech columnist Nick Bilton. “No one knew it was going to get so big. I’d say I ended up on top.”Now, before you kick off your pizza party, let’s take a quick trip down memory lane. Bite first into Hanyecz’s historic BitcoinTalk pizza post, in which he describes his hankering for a pizza delivery paid in BTC:I’ll pay 10,000 bitcoins for a couple of pizzas.. like maybe 2 large ones so I have some left over for the next day.  I like having left over pizza to nibble on later.  You can make the pizza yourself and bring it to my house or order it for me from a delivery place, but what I’m aiming for is getting food delivered in exchange for bitcoins where I don’t have to order or prepare it myself, kind of like ordering a ‘breakfast platter’ at a hotel or something, they just bring you something to eat and you’re happy!If you’re interested please let me know and we can work out a dealThanks,LaszloIf you happen to have some Bitcoin pizza money to spare, you can order yours now from, though it won’t be as cool as when Hanyecz ordered his back in the day, before Bitcoin went boom.   Related: 6 Crazy Things You Can Buy With Bitcoin (Paradise Included)last_img read more
