Just in time for the holidays, Google is throwing its money, brain power and technology at the humble spoon. Of course these spoons (don't call them spoogles) are a bit more than your basic utensil: Using hundreds of algorithms, they allow people with essential tremors and Parkinson's disease to eat without spilling.
New computer models that show how microtubules age are the first to match experimental results and help explain the dynamic processes behind an essential component of every living cell, according to Rice Univ. scientists. The results could help scientists fine-tune medications that manipulate microtubules to treat cancer and other diseases.
Conventional treatment seeks to eradicate cancer cells by drugs and therapy delivered from outside the cell, which may also affect (and potentially harm) nearby normal cells. In contrast to conventional cancer therapy, a Univ. of Cincinnati team has developed several novel designs for iron-oxide based nanoparticles that detect, diagnose and destroy cancer cells using photo-thermal therapy (PTT).
How does glass transition from a liquid to its familiar solid state? How does this common material transport heat and sound? And what microscopic changes occur when a glass gains rigidity as it cools? A team of researchers at New York Univ.'s Center for Soft Matter Research offers a theoretical explanation for these processes in Proceedings of the National Academy of Sciences.
One of the most mysterious forms of life may turn out to be a rich and untapped source of antibacterial drugs. The mysterious life form is Archaea, a family of single-celled organisms that thrive in environments like boiling hydrothermal pools and smoking deep sea vents which are too extreme for most other species to survive.
Powered lower limb prosthetics hold promise for improving the mobility of amputees, but errors in the technology may also cause some users to stumble or fall. New research examines exactly what happens when these technologies fail, with the goal of developing a new generation of more robust powered prostheses.
Scientists at SLAC National Accelerator Laboratory are combining the speed and precision of robots with one of the brightest x-ray lasers on the planet for pioneering studies of proteins important to biology and drug discovery. The new system uses robotics and other automated components to precisely maneuver delicate samples for study with the x-ray laser pulses at SLAC’s Linac Coherent Light Source.
Scientists from Lawrence Berkeley National Laboratory have learned new details about how an important tumor-suppressing protein, called p53, binds to the human genome. As with many things in life, they found that context makes a big difference. The researchers mapped the places where p53 binds to the genome in a human cancer cell line.
Farmers interested in bioenergy crops now have a resource to help them determine which kind of bioenergy crop would grow best in their regions and what kind of harvest to expect. Researchers at the Univ. of Illinois have published a study identifying yield zones for three major bioenergy crops.
Researchers at Nano-Meta Technologies Inc. have shown how to overcome key limitations of a material that could enable the magnetic storage industry to achieve data-recording densities far beyond today's computers. The new technology could make it possible to record data on an unprecedented small scale using tiny "nanoantennas" and to increase the amount of data that can be stored on a standard magnetic disk by 10 to 100 times.
Rice Univ. is preparing to offer its researchers who deal in “big data” the opportunity to compute in the cloud with fewer barriers. Rice is installing the Big Research Data Cloud (BiRD Cloud), which will allow for cloud bursting. That means data-intensive tasks can spill over into outside cloud-computing systems when necessary, essentially providing unlimited computing capacity.
Scientists at the Canadian Light Source are on the forefront of battery technology using cheaper materials with higher energy and better recharging rates that make them ideal for electric vehicles (EVs). The switch from conventional internal combustion engines to EVs is well underway. However, limited mileage of current EVs due to the confined energy storage capability of available battery systems is why these vehicles aren't more common.
Scientists at The Scripps Research Institute (TSRI) have discovered how one gene is essential to hearing, uncovering a cause of deafness and suggesting new avenues for therapies. The new study, published in Neuron, shows how mutations in a gene called Tmie can cause deafness from birth. Underlining the critical nature of their findings, researchers were able to reintroduce the gene in mice and restore the process underpinning hearing.
Using ocean observations and a large suite of climate models, Lawrence Livermore National Laboratory (LLNL) scientists have found that long-term salinity changes have a stronger influence on regional sea level changes than previously thought.
In a study that identifies a new, "direct fingerprint" of human activity on Earth, scientists have found that agricultural crops play a big role in seasonal swings of carbon dioxide in the atmosphere. The new findings from Boston Univ., the Univ. of Michigan and other institutions reveal a nuance in the carbon cycle that could help scientists understand and predict how Earth's vegetation will react as the globe warms.
Researchers at Massachusetts Institute of Technology say they have carried out a theoretical analysis showing that a family of 2-D materials exhibits exotic quantum properties that may enable a new type of nanoscale electronics. These materials are predicted to show a phenomenon called the quantum spin Hall (QSH) effect, and belong to a class of materials known as transition metal dichalcogenides, with layers a few atoms thick.
Researchers from North Carolina State Univ. have developed a technique that allows ultrasound to penetrate bone or metal, using customized structures that offset the distortion usually caused by these so-called “aberrating layers.” The researchers addressed this problem by designing customized metamaterial structures that take into account the acoustic properties of the aberrating layer and offsetting them.
Enzymes carry out fundamental biological processes such as photosynthesis, nitrogen fixation and respiration, with the help of clusters of metal atoms as "active" sites. But scientists lack basic information about their function because the states thought to be critical to their chemical abilities cannot be experimentally observed.
A potential path to identify imperfections and improve the quality of nanomaterials for use in next-generation solar cells has emerged from a collaboration of Univ. of Oregon and industry researchers. To increase light-harvesting efficiency of solar cells beyond silicon's limit of about 29%, manufacturers have used layers of chemically synthesized semiconductor nanocrystals.
New findings by a Johns Hopkins Univ.-led team reveal long unknown details about carbon deep beneath the Earth’s surface and suggest ways this subterranean carbon might have influenced the history of life on the planet. The team also developed a new, related theory about how diamonds form in the Earth’s mantle.
Recent studies showing acid ceramidase (AC) to be upregulated in melanoma, lung and prostate cancers have made the enzyme a desired target for novel synthetic inhibitor compounds. In Angewandte Chemie, scientists with the Univ. of California, Irvine School of Medicine and the Italian Institute of Technology describe the very first class of AC inhibitors that may aid in the efficacy of chemotherapies.
