New technique could transform low-energy light detection
Researchers have discovered a way to use standard semiconductors to detect light over a much broader range of wavelengths. The technology, developed by a team of scientists at Georgia State University and the University of Leeds, opens new possibilities in solar power generation and low-energy light detection.

Games linked to aggression if players can't master technology
Playing electronic games can make people feel aggressive, but new research finds that the reason has little to do with violent content. Researchers from the University of Oxford in the UK and the University of Rochester in the US carried out lab tests in which volunteers played both violent and non-violent games.

Glasses strong as steel: A fast way to find the best
Glasses strong as steel: A fast way to find the best
Scientists at Yale University have devised a dramatically faster way of identifying and characterizing complex alloys known as bulk metallic glasses (BMGs), a versatile type of pliable glass that's stronger than steel. Using traditional methods, it usually takes a full day to identify a single metal alloy appropriate for making BMGs.

Ten great discoveries: A Wi-Fi virus that spreads like a cold
For National Science and Engineering Week , we are celebrating 10 great scientific advances made at the University of Liverpool. Over the 10 days of the event, we will be highlighting a different advance each day to show what science can achieve. Our eighth advance and the most recent in the series is the creation of a software virus which can spread over Wi-Fi networks.

Discovery of New Semiconductor Holds Promise for 2D Physics and Electronics
Discovery of New Semiconductor Holds Promise for 2D Physics and Electronics
From super-lubricants, to solar cells, to the fledgling technology of valleytronics, there is much to be excited about with the discovery of a unique new two-dimensional semiconductor, rhenium disulfide, by researchers at Berkeley Lab's Molecular Foundry. Rhenium disulfide, unlike molybdenum disulfide and other dichalcogenides, behaves electronically as if it were a 2D monolayer even as a 3D bulk material.

MEMO: POLARBEAR scientists available for comment on cosmic microwave background & inflation
MEMO: POLARBEAR scientists available for comment on cosmic microwave background & inflation
The expected announcement today (Monday, March 17) from Harvard's Center for Astrophysics that the BICEP2 (Background Imaging of Cosmic Extragalactic Polarization) experiment may have found proof of inflation in the early universe comes on the heels of a March 10 report from a rival group, POLARBEAR , that similar measurements of microwave background polarization can be used to map the large scale structure of the universe, and perhaps determine the masses of neutrinos.

Watch: Scientists ‘herd’ cells in new approach to tissue engineering
Videos show the effect of electric fields on the movement of epithelial cells. The first clip shows the cells migrating normally until the electric field is turned on, causing the population to move right. In the second video, the electric field causes the population of cells to make a U-turn.

Atomically Thin Solar Cells
Ultrathin layers made of Tungsten and Selenium have been created at the Vienna University of Technology. Experiments show that they may be used as flexible, semi-transparent solar cells. It does not get any thinner than this: The novel material graphene consists of only one atomic layer of carbon atoms and exhibits very special electronic properties.

Observed live with x-ray laser: electricity controls magnetism
Observed live with x-ray laser: electricity controls magnetism
Data on a hard drive is stored by flipping small magnetic domains. Researchers have now changed the magnetic arrangement in a material much faster than is possible with today's hard drives. The researchers used a new technique where an electric field triggers these changes, in contrast to the magnetic fields commonly used in consumer devices.

Future of cyber security is in the mind
The research draws on psychological studies and uses mathematical models to improve how decisions are made when dealing with complex security IT problems The University of Liverpool is developing a new tool that can protect organisations of all sizes from cyber threats. Cyber security is recognised as a serious challenge to economic and national security and it is estimated to cost the UK economy £10billion a year.

Tiny tool measures heat at the nanoscale
Tiny tool measures heat at the nanoscale
How heat flows at the nanoscale can be very different than at larger scales. Understanding how surfaces affect the transport of the fundamental units of heat, called phonons, could impact everything from thermoelectric materials to microelectronic cooling devices. Cornell researchers have developed a new way to precisely measure the extremely subtle movement of heat in nanostructures.

Wifi virus latest threat to future IT security
The researchers found the virus was able to avoid detection and identify the points at which WiFi access is least protected by encryption and passwords Researchers at the University of Liverpool have shown for the first time that WiFi networks can be infected with a virus that can move through densely populated areas as efficiently as the common cold spreads between humans.

Pinwheel ’living’ crystals and the origin of life
ANN ARBOR-Simply making nanoparticles spin coaxes them to arrange themselves into what University of Michigan researchers call 'living rotating crystals' that could serve as a nanopump. They may also, incidentally, shed light on the origin of life itself. The researchers refer to the crystals as 'living' because they, in a sense, take on a life of their own from very simple rules.

On the Road to Mottronics: Researchers at the Advanced Light Source Find Key to Controlling the Electronic and Magnetic Properties of Mott Thin Films
On the Road to Mottronics: Researchers at the Advanced Light Source Find Key to Controlling the Electronic and Magnetic Properties of Mott Thin Films
"Mottronics" is a term seemingly destined to become familiar to aficionados of electronic gadgets. Named for the Nobel laureate   Nevill Francis Mott, Mottronics involve materials - mostly metal oxides – that can be induced to transition between electrically conductive and insulating phases. If these phase transitions can be controlled, Mott materials hold great promise for future transistors and memories that feature higher energy efficiencies and faster switching speeds than today's devices.

Maths problem solved but it’s impossible to check
Dr Boris Konev and Dr Alexei Lisitsa are now running software in an attempt to find a result for discrepancy 3 University of Liverpool academics made significant progress towards solving an 80 year old maths puzzle using a computer programme, but the resulting proof is so massive it's impossible for any human to check.

MIT robot may accelerate trials for stroke medications
Robot protocol able to cut time and cost of Phase III drug trials by 70 percent. The development of drugs to treat acute stroke or aid in stroke recovery is a multibillion-dollar endeavor that only rarely pays off in the form of government-approved pharmaceuticals. Drug companies spend years testing safety and dosage in the clinic, only to find in Phase III clinical efficacy trials that target compounds have little to no benefit.

Maybe robots should, like, hedge a little
Maybe robots should, like, hedge a little
Before long, robots will be giving us helpful advice, but we don't want them to be snippy about it. Research at Cornell and Carnegie Mellon universities suggests that if they sound a little less sure of themselves and throw in a few of the meaningless words humans are fond of, listeners will have a more positive response.

Foot study may impact design of running shoes
Foot study may impact design of running shoes
New insights into how foot muscles support the arch of the foot could spark a change in the design of running shoes, following a study led by The University of Queensland. The study's findings are also expected to impact the treatment of foot conditions, the design of efficient prosthetic and robot limbs and improve understanding of how humans came to walk and run efficiently on two feet.
