Boron: Physics’ latest superconducting material

by Gordon Hunt


There’s a decent chance that boron is the only natural two-dimensional superconductive element on Earth, following the discovery of its unique low-temperature properties.

Researchers at Rice University in Texas have established that boron is a resistance-free superconductor in the right environment, moving one major step beyond the fact that it was previously accepted in theory.

The problem – there’s always one – is it’s fairly useless in low temperatures -256oC, however it’s probably the only 2D superconductor around so very small circuits are primed for a boron fix.

Evgeni Penev, Alex Kutana and Boris Yakobson published their paperon the discovery at the same time that samples of the materials began being made in labs in the US and China. This was an inevitable development after an earlier paper from Yakobson and his colleagues predicted how it could be made.

In the 100 years since superconductivity was established, never before had it been tested on boron, according to Penev, who noted the lightness of its atomic mass was always appealing.

“If it’s metallic too, these are two major prerequisites for superconductivity. That means at low temperatures, electrons can pair up in a kind of dance in the crystal,” he said.

“Lower dimensionality is also helpful,” Yakobson said. “It may be the only, or one of very few, two-dimensional metals. So there are three factors that gave the initial motivation for us to pursue the research. Then we just got more and more excited as we got into it.”

Versatility abound

Penev said that boron works as, given its opposite momenta and spins, it creates what are called Cooper pairs. This means they attract each other at low temperatures with the help of lattice vibrations, giving it superconductivity properties.

“We’ve been working to characterise boron for years, from cage clusters to nanotubes to planer sheets, but the fact that these papers appeared so close together means these labs can now test our theories,” Yakobson said.

Boron is quite a versatile material, recently used in a project to successfully drag water-splitting solar energy production one step closer to reality.

A boron-doped photovoltaic project between the Tyndall National Institute in Cork, Queen’s University in Belfast and Stanford University in California just broke the record for generating a voltage from a solar cell submerged in water.

Starting from the four innermost letters and working to the outermost ring, this table shows shows which three-letter base sequence or codon encodes which amino acid. In the journal <i>Angewandte Chemie International Ed.</i>, researchers from the US Department of Energy Joint Genome Institute (DOE JGI), a DOE Office of Science User Facility, and Yale University have discovered that microorganisms recognize more than one codon for the rare, genetically encoded amino acid selenocysteine.

A, C, G and T – stand in for the four chemical bases that store information in DNA. A sequence of these same four letters, repeating in a particular order, genetically defines an organism. Within the genome sequence are shorter, three-letter codons that represent one of the 20 regularly used amino acids, with three of the possible 64 three-letter codons reserved for stop signals. These amino acids are the building blocks of proteins that carry out a myriad of functions. For example, the amino acid alanine can be represented by the three-letter codon GCU and the amino acid cysteine by the three-letter codon UGU. In some organisms, the three-letter codon UGA, which normally signals the end of a protein-coding gene, is hijacked to code for a rare genetically encoded amino acid called selenocysteine. Published ahead online March 16, 2016 in the journal Angewandte Chemie International Ed., researchers from the U.S. Department of Energy Joint Genome Institute (DOE JGI), a DOE Office of Science User Facility, and Yale University have discovered that microorganisms recognize more than one codon for selenocysteine. The finding adds credence to recent studies indicating that an organism’s genetic vocabulary is not as constrained as had been long held.

The work is a follow-up to two 2014 publications; a Science paper by the JGI group finding that some organisms interpret the three “stop” codons which terminate translation to mean anything but. A synthetic biology experiment of the Yale group published in an Angewandte Chemie International Ed. paper revealed the astonishing fact that almost all codons in Escherichia coli could be replaced by selenocysteine. This posed the question whether the same phenomenon can also occur in nature.

“Access to the tremendous resources at the JGI allowed us to quickly test challenging hypotheses generated from my research projects that have been supported over the long-term by DOE Basic Energy Sicences and the National Institutes of Health,” said Dieter Soll, Sterling Professor of Molecular Biophysics and Biochemistry Professor of Chemistry at Yale, the lead author of the paper. Thus a fruitful collaboration resulted; the combined team scanned trillions of base pairs of public microbial genomes and unassembled metagenome data in the National Center for Biotechnology Information and the DOE JGI’s Integrated Microbial Genomes (IMG) data management system to find stop codon reassignments in bacteria and bacteriophages. Delving into genomic data from uncultured microbes afforded researchers the opportunity to learn more about how microbes behave in their natural environments, which in turn provides information on their management of the various biogeochemical cycles that help maintain the Earth.

From approximately 6.4 trillion bases of metagenomic sequence and 25,000 microbial genomes, the team identified several species that recognize the stop codons UAG and UAA, in addition to 10 sense codons, as acceptable variants for the selenocysteine codon UGA.

The findings, the team reported, “opens our minds to the possible existence of other coding schemes… Overall our approach provides new evidence of a limited but unequivocal plasticity of the genetic code whose secrets still lie hidden in the majority of unsequenced organisms.”

This finding also illustrates the context-dependency of the genetic code, that accurately “reading” the code (and interpreting DNA sequences) and ultimately “writing” DNA (synthesizing sequences to carry out defined functions in bioenergy or environmental sciences) will require study of the language of DNA past the introductory course level.

Nest, Google’s $3 Billion Bet, May Be in Trouble

Could Nest be facing a brain drain?

In 2014, Google bought smart-home appliance start-up Nest for $3.2 billion. Last year, the company was adopted under the umbrella of Google parent company Alphabet, which houses several ambitious, experimental projects. But Alphabet seems to be putting pressure on its so-called “moonshots”—which don’t necessarily generate much money for the company—including Nest, which is already facing troubles of its own. A profile last week in The Information cast Nest C.E.O. Tony Fadell as a ruthless leader, while a blog post written in response by Dropcam founder Greg Duffy, whose company was acquired by Nest in a $555 million cash deal in 2014, was deeply critical of Fadell.

Now, a new report from Re/code suggests that Nest’s $340 million 2015 revenue, while impressive, is still short of Wall Street expectations, which range between $400 million and $672 million. When Google bought Nest, it set a $300 million internal sales target for the company; according to sources who spoke with Re/code, Nest only made its numbers as a result of its acquisition of Dropcam, a security-camera start-up. And soon, Nest could have other problems on its hands.

More troubling for Nest is that many of its employees are nearing the time at which their stock options vest—the end of a three-year cycle intended to retain employees after the company was acquired. Fadell’s guaranteed operating budget, reported to be as much as $500 million annually, expires in 2016, along with the stock-vesting schedule. Sources tell Re/code that “some key executives” at Nest could depart once employees’ stocks vest later this year. Former employees say that Dropcam’s sales growth was initially higher than Nest’s other products—a smart thermostat and a smoke detector called Protect—but then Nest rebranded Dropcam as Nest Cam, and sales began to slow.

The turmoil at Nest comes as Google appears to be scaling back its more gutsy initiatives. Two weeks ago, it was reported that the company had decided to part ways with robotics company Boston Dynamics, which it bought in late 2013. Boston Dynamics and its parent company, Replicant, are among a number of moonshots that have faced greater scrutiny since the creation of Alphabet, which allows investors to look more closely at how those projects stand up next to the company’s more lucrative, core Internet businesses. Google also announced Thursday it is folding its debit card program, which it said had millions of customers. Nest, Google’s self-driving-car project, and Google Fiber, for instance, are all Alphabet projects, while Google oversees Android, Google search, and YouTube. Google’s projects, for the most part, have clear revenue paths; the Alphabet projects are still more hypothetical and experimental.

Eating beans, chickpeas or lentils may help with weight loss

Lentils as a superfoodJust one serving a day of pulses, such as lentils, could help with weight loss says a new Canadian study.

Published Thursday, March 31, 2016 8:58AM EDT

Just one serving a day of pulses, including beans, peas, chickpeas or lentils, could help with weight loss says a new Canadian study published this week in The American Journal of Clinical Nutrition.

The meta-analysis, carried out by a team from St. Michael’s Hospital, looked at a total of 940 participants from 21 different clinical trials.

The data showed that after adding a single serving of pulses to their diet — about 3/4 cup (130 grams) — participants lost an average 0.34 kg (0.75 pounds) over a six-week period, and without making an effort to reduce any other foods.

The study’s lead author, Dr. Russell de Souza, commented on the results, saying, “Though the weight loss was small, our findings suggest that simply including pulses in your diet may help you lose weight, and we think more importantly, prevent you from gaining it back after you lose it.”

The study also builds on and supports the hospital’s previous work on the health benefits of a daily serving of pulses, which found that they can increase the feeling of fullness by 31 per cent, and decrease levels of “bad cholesterol” by 5 per cent.

This feeling of fullness could be important in controlling weight, with Dr de Souza commenting that 90 percent of weight loss interventions fail, possibly as a results of hunger and food cravings.

Dr de Souza also added that, “Despite their known health benefits, only 13 percent of Canadians eat pulses on any given day and most do not eat the full serving. So there is room for most of us to incorporate dietary pulses in our diet and realize potential weight management benefits.”

In an effort to increase public awareness on the many health benefits of pulses, the Food and Agriculture Organization of the United Nations (FAO) has declared 2016 the International Year of Pulses.

The new findings come after the news last week that a high-protein diet, of which pulses are a great source, could help overweight and obese adults sleep better.

A group of researchers from Osaka University and The University of Tokyo succeeded in synthesizing two-dimensional layers of bismuth (Bi) with Dirac electrons and magnetic multilayer blocks of europium.

Using flux growth in a high vacuum, this group succeeded in the synthesis of EuMnBi2, a layered substance of high-quality single crystal thought to have both properties of Dirac fermions and magnets. This substance features hybrid architecture consisting of two-dimensional layers of Bi with Dirac electrons and europium with magnetic properties.
In order to verify the strong correlation between Dirac fermions and the magnetic state, this group measured electric resistance in a strong magnetic field (some 30 to 60 tesla) at The Institute for Solid State Physics of The University of Tokyo and the High Field Laboratory for Superconducting Materials of Tohoku University.
In order to elucidate the magnetic state, the group conducted magnetic scattering experiments of radiated x-rays at the Photon Factory of the Institute of Materials Structure Science, High Energy Accelerator Research Organization.
As a result, they found that electric resistance significantly changed according to the magnetic order of europium. They also found that when a magnetic field was applied perpendicularly to the surface and the direction of magnetic moment was rotated by 90 degrees, the conductivity perpendicular to the surface was suppressed by 10 percent and Dirac fermions were confined within the surface.
Furthermore, by confining Dirac electrons in the two-dimensional layer of Bi, or the superconducting layer, through the use of this effect, this joint group achieved a bulk half-integer quantum Hall effect, in which the value of the Hall resistance becomes discrete, in a bulk magnet of Dirac fermions for the first time.
This group’s achievement will develop a new field of study, strong correlated quantum conductance of Dirac electrons, and contribute to realizing super high-speed spintronics, the foundation of high-speed and energy-saving electronics.

MIT Hyperloop win Ellon Musk’s SpaceX Hyperloop Design Competition – Overland Park Tech Day

A team of students from MIT has won the top spot in a competition for the SpaceX Hyperloop high-speed transportation system. The competition was held at the Texas A & M University over 100 other design teams from around the world and included instead. The MIT students are all students and won the overall design award for the pod that will go inside the Hyperloop.

The top teams to build their pods and test them on the world’s first Hyperloop Test Track, adjacent built at SpaceX of Hawthorne, California, headquarters

With strengths in aerospace, mechanical and electrical engineering and computer science, the MIT team focused on speed Hyperloop-brake and levitation. Based placed for the latter problem, a model for the electrodynamic suspension which is based on strong magnet via a conductive plate which is in this case, the aluminum rail SpaceX they developed. The magnets generate lift. “The beauty of the system have developed, we,” says Cherry, “is that it is completely passive, an elegant property that will make our pod very scalable.”

This innovation, a departure from the original concept of Musk pods float on a cushion of air, requires a major research thrust. “None of us knew anything about magnets, and it was definitely a steep learning curve for us,” says Cherry.

Massachusetts Institute of Technology in Cambridge, Massachusetts, was for a competition among the more than 1,000 students at the Texas A & M University in College Station with the names of the winners Friday.

The Hyperloop is a proposed high-speed traffic transport Musk floor concept on “pods” 20-30 people through a tube 12 feet in diameter at a speed of about 700 mph.

The 24-person UCI team built a scale model of their HyperXite pod (pronounced hyper Excite) for competition. The concept to float with compressed air and glide the Pod on a track. Strong magnet would serve as breaks for the 1,067-pound car.

Dean Defuria, the team captain to float and network systems of the train, said last week, 1-foot scale model of the team had been given up to speeds of 219 mph.

The main prize went to MIT developed Hyperloop teams design for a 550-pound pod, go to 360 feet per second.

The interior of the tube would be a near-vacuum and in the absence of air or surface friction, the sleeves are provided for traveling at about 750 mph with low-energy drive. The MIT team has been working students from a variety of engineering disciplines and has focused on a sub-scale prototype pod since the fall.

The design of the capsule is required to be equipped with sensors that provide real-time telemetry data during the journey on the mile-long test track can be transferred. The next step is to move from simulations with an actual product that can be tested with brake systems and magnets.

The team has already passed two milestones with SpaceX, but the remaining hurdle is money. If the team to raise $ 60,000 needed to make a half-scale model, they can make it to the finals in June, Defuria said.

In the past week contest, a team from Massachusetts Institute of Technology in Cambridge, Massachusetts, was named the winner Saturday.

Apple developing new batteries to improve energy capacity in devices

Apple is hiring scientists to create batteries based on new materials, but it’s not certain when or if they will reach devices

Apple can’t yet boast of significantly longer battery life in devices, but the company is looking to change that.

The company is researching new types of batteries that could potentially help PCs, mobile devices and wearable devices run much longer without a recharge.

Job listings posted over the last two months point to Apple researching new battery technologies and looking to improve on current lithium-ion architectures.

Apple is looking for materials scientists; the jobs involve evaluating and testing new materials beyond the current lithium-ion technology.

The company has posted job listings for scientists who specialize in electrodes andelectrolytes, indicating that the company is researching new technologies in cathodes, anodes and electrolytes, which are the building blocks of batteries.

In current batteries, lithium ions move from the cathode to the anode for storage. During a discharge, the lithium ions move from an anode to cathode and to the device using the battery. Liquid electrolytes allow charged lithium ions to move around.

Apple seems to be focusing on ceramic as an electrolyte, which has been proven in labs to provide faster charging and safer batteries.

One job listing points to Apple looking to improve on current lithium-ion battery with the help of new materials. Scientists are mainly looking to improve electrolytes, which could help batteries charge faster and make them less flammable.

Current lithium-ion battery technology has reached its limits in terms of energy capacity, and is also considered unsafe due to fire risk. Battery research has stepped up in the last decade, with scientists developing new types of batteries that have more energy capacity and potentially are safer.

Apple is also hiring people that can take battery technology from the lab to factories, which is a challenge for university researchers trying to commercialize battery technologies.

Some new batteries like silver-zinc, which came out about eight years ago, failed because they were expensive. Lithium-ion batteries are relatively inexpensive to produce, but Apple could use scale of manufacturing to bring down the cost of making new types of batteries.

Apple has already been granted a patent on a solid-state battery, which is considered the next big technology in battery research. A startup called Prieto Battery is separately developing a solid-state battery that could be in devices running on Intel chips by 2017. Solid state batteries have a different structure and could potentially hold five times more energy capacity than lithium-ion batteries.

A new battery technology could also play a role in Apple’s plans to develop a car. Apple did not return request for comment on new battery technologies it may be working on, or when new technology would reach devices.

9 Ways to Make Your Smart Home More Secure

Security is set to become the hot button issue in the smart home this year, as more connected devices come online and more hackers attempt to infiltrate corporate and consumer networks through connected gadgets. The FBI even issued a warning about connected home products.

The concerns about security and the smart home are well-founded. Several devices from connected cameras to smart home hubs have been hacked. Even light bulbs aren’t immune.

A survey issued by Intel on Thursday found that 77 percent of those asked believe smart homes will be as common in 2025 as smartphones are today, but 66 percent are also very concerned about smart home data being hacked by cybercriminals.

The looming threat of the hacked home is why the Atlantic Council worked with three security researchers to issue nine recommendations to make the smart home more secure. The report is a collaboration between the Atlantic Council think tank and I Am The Cavalry, a independent security research group. I Am The Cavalry has issued a framework for securing connected cars and connected medical devices.

Beau Woods, an author of the report and the deputy director of the Cyber Statecraft Initiative at the Atlantic Council, explained fear of hacking has hindered consumer acceptance of the smart home. The smaller market has its own effects on the industry’s security practices, making it harder for start-ups to invest in security, and leading them to business models that may drive even more consumers away.

The goal of the Atlantic Council’s report is to lay the groundwork for the creation of a new smart home security framework in a few months. Most of the recommendations are uncontroversial, but I can’t think of a single product that follows all of them today. They are:

  • Security by design—Assume that someone is always trying to hack your product and react accordingly. Also, keep devices and software as simple as possible to reduce the surface area available to attack.
  • Third-party collaboration—Don’t sue people who bring security flaws to you.
  • Failure investigation—Track your failures and review them so they can’t happen again.
  • Remote updates—Build for remote updates, and ensure the means of delivering those updates are secure.
  • Safe failure modes—When something is hacked, make sure it can’t do much damage. Today weaknesses in the smart home tend to spread from one device to others. Efforts like Nest’s Weave protocol, which ensures that devices can only talk to certain other devices, can help stop the spread of malicious software, for example.
  • Standalone operation—Make sure the manufacturer understands and communicates what parts of a device will work if there is no Internet connectivity. Also, it may make sense to buy back obsolete devices rather than continue to support them.
  • Safe options and defaults—Ensure that default settings are “reasonably” safe and tell owners how to further tweak and secure their devices. Don’t force them to become a network engineer.
  • Data protective measures—Make sure customers understand how their data is protected. Ensure they know how to safely remove remove data if they lose or sell the device. Additionally, make sure they can remove their data in case of device theft.
  • Informed consent for data use—Tell users how their data will be used and how they can opt out. Don’t forget to include a section on how you plan to deal with their data in case of a sale or if you intend to share the data with third parties.

For the last one I’d like the industry to also understand what third parties plan to do with their user data, and communicate that to consumers. I might trust Amazon with my Echo$179.99 at Amazon utterances, but if Amazon wants to share that with a third party, it’s not enough to say it is doing so. I’d want to know that Amazon has limited what that third-party can do with my data.

In general, these recommendations codify the current best practices for device security without directly mandating how the devices should be secured. You won’t find dictates about how databases of user passwords should be secured or what level of encryption the devices should use.

Already, companies are stepping up in those areas, but the Atlantic Council report brings up a bigger challenges, such as the lack of incentives for companies to build in better security. From the report:

In the United States, there is no software liability, so the costs of security failure fall to the buyer. Though many device makers are conscious of security concerns and want to do the right thing, investing in better security may not make sense from a monetary, cost-benefit standpoint. For device makers, the cost of reducing security risks may not outweigh the benefits from securing their products—especially if they are delayed to market. Furthermore, any incentive to invest in better security may be even smaller, considering that many of the potential security risks might never affect consumers. How much should a device maker spend when the costs of failure do not directly affect them?

Steve Grobman, chief technology officer for Intel Security, points out another problem with incentives. Namely that because many of these devices have a long life cycle but are relatively low-margin, manufacturers may not want to support them over the entire life of the product.

“How do we change the incentive model when device life cycles and security maintenance on devices are not aligned?” he asks.

Instead of a regulatory solution, such as the FTC stepping in to assess fines, Grobman thinks that consumer education about what they are buying will help. A more likely area of help will come from new business models where device makers can generate revenue in the long term from a connected device. At that point they will have an incentive to keep the product patched and working.

Until then, manufacturers have the Atlantic Council and I Am The Cavalry recommendations.
