The prospect of materials being able to carry electrical currents without resistance has been of great interest to people for a long time now, but achieving it has proven very difficult. Superconductivity is a somewhat fragile state, as many things can disrupt it, so we need to find ways to either remove these disruptions, or control them. Researchers at John Hopkins University have done the latter by trapping electron vortices.

Electron vortices occur in superconductors when they are exposed to magnetic fields, and they can disrupt the resistance-free supercurrents as they move around. Along the edge of the superconductor, the vortices will be pinned in place, but in the bulk of a material it is much harder to stop them from moving. The researchers' solution to the problem was to make an aluminum nanowire, as it is mostly edges. This caused the vortices to become trapped on the edge and form a single row, which the supercurrent was able to avoid.

Besides demonstrating a way to stop these vortices from interfering, this research could also prove useful in other ways. Some day we could see the vortices used to transmit information, like how electrical charges are used today.

I am starting to wonder if graphene is more amazing or ridiculous as its number of applications continues to increase. Researchers at the University of Manchester have discovered that graphene oxide could be used to treat cancer. More specifically it can target cancer stem cells and prevent them from forming tumor-spheres.

Cancer stem cells (CSCs) are exactly what they sound like; cancer cells that can differentiate into other cancers and are what causes cancer to spread. They also have to do with cancer recurring after treatment. Graphene oxide has been investigated for use in biomedicine before, because it is able to enter or attach to cell surfaces, but this is the first time it has been shown to work as an anti-cancer drug on its own. It appears it attaches to the surfaces of the CSCs and blocks the pathways used to form tumor-spheres. The researchers also observed it triggering the differentiation of the CSCs into non-cancer stem cells. The tests were done with six different cancer types (breast, pancreatic, lung, brain, ovarian, and prostate) and it was effective against all of them, suggesting it could work with a larger number of cancers, and perhaps even all of them.

Normally CSCs are unaffected by radiation and chemotherapies, which kill bulk cancer cells, so a means to target them directly is very important. Of course a lot of work will have to be done before graphene oxide flakes could be used for treating cancer, but this is still a very significant discovery.

Social media services like Twitter are taking the safety of its users very seriously. Facebook is doing the same, as it has just announced updated tools that are able provide a wealth of resources, advice, and support to people who may be struggling with suicide. The updated tools come after the company partnered with a variety of mental health organizations such as Forefront, Now Matters Now, the National Suicide Prevention Lifeline, and Save.org, as well as people who have dealt with self-injury or suicide thoughts. Users of Facebook who see a direct threat of suicide are being urged to contact their local emergency services immediately, of course, but the social networking service is touting that it has teams that work every hour of every day to review any report that comes in. The team is able to send resources to those in distress, and Facebook now allows users who flagged the self-harm post to call or message their distressed friend in order to let them know that they care.

The updated tools are expected to roll out to Facebook users located in the United States in the coming months, and the social networking service remains committed to improving its tools for users located outside of the United States.

Many people want to see a future filled with superconductors, because these materials are capable of transmitting electricity without resistance. One of the reasons why we are not currently using them much is that they require being cooled to very low temperatures; some near absolute zero. Researchers at the University of Southern California however have recently discovered a potentially new class of superconductors based on superatoms.

Superatoms are homogenous clusters of normal atoms, so even though they consist of many atoms, they will act as one, though a rather large one. This made the researchers wonder if some phenomena, such as Cooper pairs, could by exhibited by the superatoms. Cooper pairs are pairs of electrons that form in superconductors and help achieve that superconductivity. To test this hypothesis the research built superatoms containing 37, 44, 66, and 68 atoms of aluminum and then shot lasers of increasing energy at them. Normally laser pulses of higher energy will cause more electrons to be ejected, but at certain energy levels the electrons resisted.

One explanation for this resistance is that the electrons had formed Cooper pairs, which is supported by fewer electrons being knocked at as the temperature dropped, with the critical point around 100 K. While that is still a pretty cold temperature, it is only the beginning so with more work, the researchers think they may be able to create superatoms with higher superconducting critical points.

Google Flights is the latest tool from the Internet giant, taking aim at companies in the travel space and offering some interesting features. Google will highlight the cheapest flight on each day and will also offer an easy comparison across months of the year to find what season is best for travel. Flights will show users the flight prices given a time, origin, and destination, but also gives users the ability to specify a time and origin and receive suggestions on where to go. According to Google, more than half of all travelers "don’t know where they’re going to travel when they sit down to plan." Users can search by regions rather than specific cities with queries like "Flights to Europe" or "Flights to Mexico." Flights will also offer a best flights metric that factors in price along with convenience, such as direct flights rather than layovers, for users that don't necessarily need the cheapest flight.

In a vote that passed by the narrowest of margins, 3-2, the FCC has approved net neutrality rules to ensure an open Internet. The passing of net neutrality effectively guarantees no single corporation will control access to the Internet, and basically means no ISP, even cellular carriers, can throttle or block traffic. So if you want to watch Netflix yet are on Comcast, Comcast cannot throttle your speed because you aren't using the Xfinity App to watch a TV show or movie. The FCC has reclassified fixed and mobile broadband as a telecommunications service, meaning it falls under the same Title II regulations as phone and cable companies (namely, it treats them as public utilities). FCC Chairman Tom Wheeler said, "the Internet is the ultimate vehicle for free expression," and ISPs should not be the ones making the rules for it. Now it looks like free and open Internet will be available for everyone, and that should be a very good thing.

The net neutrality rules ban throttling or blocking Internet traffic, ban paid prioritization, and require ISPs to disclose network management practices. ISPs cannot throttle or block access to any legal content, apps, services, or non-harmful devices, and cannot pay to force traffic to favored devices/services over others. Exceptions for heart monitoring and VoIP services that do not use "public Internet" are in place, as well as for "reasonable network management." Some other Title II requirements include provisions to investigate consumer complaints, privacy rules, and protections for people with disabilities. Content providers and network operators that connect to an ISP can tell the FCC about any unjust or unreasonable interconnection rates and policies. ISPs will also have access to utility poles and other infrastructure to make it easier to enter new areas.

One thing the net neutrality rules do not impose is unbundling, where ISPs would have to provide Internet access by itself. It means competition does not see a boost, but it does mean current ISPs should not be able to harm others in the area that compete against its services.

Comcast, AT&T, and Verizon may sue the FCC to prevent the new net neutrality rules from taking place, but when Verizon won its lawsuit back in 2010, it effectively opened the door for stricter rules. Wheeler believes the FCC is in a stronger position now than it was in 2010 thanks to the Title II classification, with net neutrality equally applied to both fixed and mobile broadband. Time will tell if that helps weaken or even curtail any lawsuits, but it may. Republicans lost the FCC vote (the two dissenting votes were by Republican chairmen) and may vote to eliminate the FCC's Title II classification, so we'll see where that leads. Some ISPs both big and small oppose the ruling, as to be expected, but others are in favor of it. Even cellular companies like Sprint and T-Mobile are in favor of net neutrality, along with the inventor of the World Wide Web, Sir Tim Berners-Lee.

The full net neutrality order is not yet available on the FCC website, as it needs to provide the Republicans' dissents in the order. It should be up before too long, however.

For decades we have known about high temperature superconductors, but despite our time with them, we know little about how they work. With such understanding it may be possible to design new superconductors that work at room temperature. There is a model that may provide the explanation, and finally researchers at Rice University with an international team have taken an important step in testing the model.

The Hubbard model was developed in the 1960s to describe the magnetic and conduction properties of electrons in transition metals and their oxides. It is actually a simple model, but it becomes exponentially more difficult to process as more electrons are involved, which is why even supercomputers have been unable to test it. The solution the Rice researchers developed is to physically model the materials in question. Instead of working with electrons moving between sites in a lattice, the researchers placed ultracold atoms in an optical lattice and watched the movement of ions in the lattice. They observed antiferromagnetic order, just as the Hubbard model predicts, and by using the Quantum Monte Carlo method, the results of the experiment were confirmed to match the Hubbard model.

Even though it was not superconductivity that was observed, this is an important step towards that goal as most parent materials of high temperature superconductors are antiferromagnetic. By developing new measurement methods and finding ways to chill the atoms even more, the researchers hope to be able to model the electron pair correlations that result in superconductivity.

The world would be a very different place if not for batteries; especially modern lithium-ion batteries. These batteries seem to be approaching their limits though, unless new technologies and materials are developed. One thing holding back some new designs has been the formation of dendrites, but researchers at the Pacific Northwest National Laboratory have found a solution to that.

Dendrites are small structures that can form in batteries and lead to reduce capacities, short circuits, and even fires. If a material for a battery's anode reacts with the electrolyte to produce dendrites, it does not matter how much better that anode would be, because the battery will fail sooner. What the PNNL researchers have been investigating is new electrolytes that prevent dendrites from forming. In this area some others of have had success with electrolyte with high salt concentrations, so that is where the researchers started. They built a circular test cell with their new electrolyte and a lithium anode. Lithium anodes can hold ten times the energy of conventional graphite anodes, but easily form dendrites. In the test cell though, instead of dendrites forming, a thin layer of lithium nodules formed, which did not short-circuit the battery.

After 1000 cycles, the test cell still held 98.4% of its original energy at 4 milliAmps per square centimeter. With such high efficiency the researchers suspect it may be possible to do away with the anode in batteries using this electrolyte, and use a current collector, but more work needs to be done to determine that.

The traditional electronics we use every day are approaching their limits, so researchers have been working on a variety of replacements, including spintronics. Instead of relying on the charge of electrons, spintronics uses the spin of the fundamental particles, which can off several performance benefits. One of the challenges still to overcome though is finding a suitable material to make spintronics out of, but researchers at the University of Michigan have created one that could do the trick.

The ideal semiconductor for spintronics could have a number of its properties precisely tuned, including magnetism and conductivity. These characteristics can be tuned already by adding atoms to the crystal lattice, but typically this happens evenly across the whole semiconductor, and spintronics would want them to vary. To hopefully solve this problem, the researchers have developed a new material without a symmetrical crystal structure. That means the holes for accepting the doping atoms vary in size across the material, allowing for new arrangements and combinations.

The semiconductor is made of iron, bismuth, and selenium and while it has great potential, it will be a bit longer before it can be tested. So far the researchers have only made it in powder form, but next they plan on making it into the thin films that would actually be used in a spintronic device.

It is hard to say how many lenses you may have encountered in your life, but I know some I have come across have been quite large and thick. That may change in the future though, as many are looking to nanotechnology and metamaterials to create flat lenses. Now researchers at Harvard University have developed the first flat lens that can work with multiple frequencies of light at the same time.

Flat lenses have been built before, but they normally only focus one color of light, while others are diffracted at different angles. The Harvard researchers' new device however uses silicon antennas on a glass substrate to bend multiple colors of light at the same angle. Other designs would bend different frequencies at different angles, but this one compensates for that. So far the researchers have built two prototype achromatic metasurfaces, as they are calling the lenses, which are able to work with three different colors. One of the lenses deflects the three colors at the same angle, while the second instead focuses all three to the same point. Simulations suggest the design could be adapted to work with many more wavelengths than just three.

Flat lenses like these could be used in a variety of optical devices, including microscopes, telescopes, and even computers. Anywhere that the bulk of traditional lenses can pose a problem, this research could be applied.

Grand Theft Auto V Now Coming to PC on April 14

A little over a month ago, Rockstar announced a small delay for Grand Theft Auto V on the PC, with its release date bumped from January 27 to March 24. At the time it said more polishing was needed, and most of us were probably expecting at least some kind of a delay. Now, it looks like Rockstar needs even more polishing, as Grand Theft Auto V for the PC is arriving on April 14. The developer says that extra time is needed to not only ensure GTA V is the best possible on PC, but that both Online Heists and GTA Online can launch without issue on day one. It is nice to have Rockstar devote that extra time to try and guarantee the PC version of GTA V is the best yet, but hopefully this is the last time the game is delayed. As a small peace offering, any pre-orders of GTA V will receive an additional $200,000 for GTA Online.

Grand Theft Auto V for the PC launches on April 14, but don't be too awfully surprised if we hear of another delay before then. Online Heists are coming to the PS4 and Xbox One on March 10, so those gamers will get to experience the new mode nearly a full month before PC. You can check out screenshots from these heists below.

There are many applications for 3D printing, and not least among them are medical uses such as specialized scaffolds that direct and promote cell growth. Researchers at the University of Sheffield have recently printed a nerve guidance conduit (NGC) which is able to guide nerve ends to repair naturally. This could have an enormous impact on future treatments for various traumatic injuries.

Normally repairing nerve damage involves surgery that sutures or grafts endings together, which tends to produce imperfect results. The use of an NGC however can improve results, as its framework of tubes guide nerve ends to toward each other for natural repairs. Some are already used in surgery, but they are limited in design and materials, which naturally restricts the injuries they can be used to treat. By using Computer Aided Design (CAD) and a form of 3D printing (laser direct writing) the Sheffield researchers are able to craft NGCs for any kind of nerve damage, and even tailor designs for specific patients.

The researchers have tested their NGCs using a novel mouse model and shown that they were able demonstrate a repair over an injury gap of 3 mm in just three weeks. With more work the printed NGCs could be made to repair larger injuries, and be made from biodegradable materials.
