A multinational group of scientists has developed implantable shape-changing transistors that can grip nerves, blood vessels and tissues. According to the researchers, these soft electronic devices can change shape within the body, while still maintaining their electronic properties, allowing them to be used in a variety of applications and treatments.

Medical physicists at the University of Texas Southwestern Medical Center are latching on to advances in the computational speed of graphics processing units (GPUs) to drastically reduce the time required to calculate radiation therapy plans. The approach also increases the accuracy of calculations, allowing for faster, more precise, and more adaptable treatment of cancer patients. Read More
Researchers at the University of Texas have identified a star that formed in the same star cluster as our Sun. Dubbed HD 162826, the star is 15 percent more massive than the Sun and resides 110 light-years away. It's hoped the discovery of this "sibling" will help us understand more about where and how the solar system originated, and might also point us to the best candidates for finding extraterrestrial life.

Artificial muscles could find use in a wide range of applications, including prosthetic limbs, robotics, exoskeletons, or pretty much any situation in which hydraulics or electric motors just aren't a practical means of moving objects. Scientists have been working on such muscles for a number of years, using materials like vanadium dioxide, graphene, carbon nanotubes and dielectric elastomers. Now, however, some of those same scientists have discovered that very powerful artificial muscles can be made from much more down-to-earth materials – regular polymer fishing line, and metal-coated nylon sewing thread.

A team of researchers at the University of Texas At Austin's Cockrell School of Engineering has effectively disproved the adage that, “if you can hear you can be heard” by creating the world's first one-way acoustic circulator. The simple, compact device, which controls the direction of sound waves, allows the user to hear without being heard. Read More
Professor J.C. Chiao and his postdoc Dr. Smitha Rao of the University of Texas at Arlington have developed a MEMS-based nickel alloy windmill so small that 10 could be mounted on a single grain of rice. Aimed at very-small-scale energy harvesting applications, these windmills could recharge batteries for smartphones, and directly power ultra-low-power electronic devices. Read More
Proteins adopt their functional three-dimensional structure by the folding of a linear chain of amino acids. Gene mutation can cause this folding process to go awry, resulting in "misfolded" proteins that are inactive or, in worse cases, exhibit modified or toxic functionality. This is the cause of a wide range of diseases, but researchers have developed a technique that fixes these misfolded proteins, allowing them to perform their intended function, thereby providing a potential cure for a number of diseases.

Sometimes everything can seem to happen at once. The new game in town is active invisibility cloaks (AIC), which use electronics and antennas to generate a cloaking field to hide an object. Two types of active cloaks have just been revealed (excuse the pun). While being impressive feats of technology, such cloaks could easily be defeated in practice. Read More
It's often a case of swings and roundabouts. If you save money by buying a house out of town, you spend more time and money commuting. If you really measure the momentum of an electron, you have no idea where the little guy is located. And now, according to a new analysis by a pair of University of Texas electrical engineers, the better an object is hidden by an invisibility cloak at a given wavelength of light, the easier it is to see at other wavelengths. Swings and roundabouts. Read More
Civilization depends on the Global Positioning System for everything from precision armaments to finding the location of the nearest pizza shop. Indeed, access to GPS's strengths and capabilities has grown so fast that little concern about its weaknesses has penetrated the public consciousness. Fortunately, assistant professor Todd Humphreys' team at the University of Texas at Austin continues to arrange splashy demonstrations of GPS spoofing. His latest is to covertly alter the course of an oceangoing yacht. Read More
