Researchers are using computer simulations to investigate how ultrasound and tiny bubbles injected into the bloodstream might break up blood clots, limiting the damage caused by a stroke in its first hours. Strokes are the most common cause of long-term disability in the U.S. and the third most common cause of death.
The worldwide market for portable electronic devices is quickly growing. These devices are predominantly battery-driven, and a challenge looms for maintaining, charging and disposing of these millions of batteries. Lawrence Berkeley National Laboratory’s Bacteriophage Power Generator offers a potential alternative.
A new theory by fluid dynamics experts at the Univ. of California, Berkeley, shows how “zombie vortices” help lead to the birth of a new star. In a recent report, a UC Berkeley-led team shows how variations in gas density lead to instability, which then generates the whirlpool-like vortices needed for stars to form.
Engineers at the Univ. of California, Berkeley have built a device that could speed up medical imaging without breaking the bank. The key ingredient? An engine lubricant called molybdenum disulfide, or MoS2, which has been sold in auto parts shops for decades.
Low-cost solar power could supply more than a third of all energy needs in the western U.S., if the nation can hit its targets for reducing the cost of solar energy, according to a new study by researchers at the Univ. of California, Berkeley. The researchers used a detailed computer model they developed of the west’s electric power grid to predict what will happen if the U.S. Dept. of Energy succeeds with its SunShot Initiative.
Researchers from NIST and the Univ. of California, Berkeley have discovered a way to create simultaneous images of both the magnetic and the electric domain structures in ferromagnetic/ferroelectric multilayer materials. By combining these two types of materials, it is possible to create low-power magnetic devices, including memory that can be controlled by electric fields instead of less energy-efficient magnetic fields.
Researchers in California have demonstrated that indium phosphide, a III-V compound, can be grown on thin sheets of metal foil in a process that is faster and cheaper than traditional methods, yet still comparable in optoelectronic characteristics. Indium phosphide is among the high-performance solar converter, but has been up to 10 times as expensive as silicon to integrate in photovoltaic cells.
A research team led by Ali Javey of the Univ. of California, Berkeley, has created the first user-interactive sensor network on flexible plastic. The new electronic skin, or e-skin, responds to touch by instantly lighting up. The more intense the pressure, the brighter the light it emits.
A team of scientists led by researchers at Lawrence Berkeley National Laboratory and the Univ. of California, Berkeley, have recently used a combination of Fourier transform infrared spectroscopy and X-ray computed tomography at the Advanced Light Source to find that vitamin D deficiency speeds the aging process of bone and reduces its quality.
Antimatter is strange stuff. It has the opposite electrical charge to matter and, when it meets its matter counterpart, the two annihilate in a flash of light. Four University of California, Berkeley, physicists are now asking whether matter and antimatter are affected differently by gravity as well. Could antimatter fall upward—that is, exhibit anti-gravity—or fall downward at a different rate?
Scientists at the University of California, Berkeley, have discovered that when we embark on a targeted search, various visual and non-visual regions of the brain mobilize to track down a person, animal, or thing. That means that if we're looking for a youngster lost in a crowd, the brain areas usually dedicated to recognizing other objects shift their focus and join the search party.
Much research has demonstrated that chronic stress elevates levels of glucocorticoid stress hormones, which impairs memory. And stress is associated with a lot of other physical ailments. But less is known about the effects of acute stress, and studies have been conflicting. Recent work shows that intense, short-lived stress causes the proliferation of new neurons, improving mental performance.
Scientists at Lawrence Livermore National Laboratory and the University of California, Berkeley have discovered new materials to capture methane, the second highest concentration greenhouse gas emitted into the atmosphere. The research team performed systematic computer simulation studies on the effectiveness of methane capture using two different materials—liquid solvents and nanoporous zeolites.
A unique atomic-scale engineering technique for turning low-efficiency photocatalytic “white” nanoparticles of titanium dioxide into high-efficiency “black” nanoparticles could be the key to clean energy technologies based on hydrogen. Samuel Mao leads the development of a technique for engineering disorder into the nanocrystalline structure of the semiconductor titanium dioxide.
Like finally seeing all the gears of a watch and how they work together, researchers from the University of California, Los Angeles and the University of California, Berkeley have, for the first time ever, solved the puzzle of how the various components of an entire telomerase enzyme complex fit together and function in a 3D structure.
Two California urban areas have the dubious distinction of being tied for second-worst traffic in the country. Commuters spend 61 hours per year being stuck in traffic in the Bay Area and in Los Angeles. A new project called Connected Corridors, led by University of California, Berkeley, is developing new technologies that will help Caltrans gather and analyze traffic data to make real-time whole-system traffic management recommendations
Atomic collapse, a phenomenon first predicted in the 1930s based on quantum mechanics and relativistic physics but never before observed, has now been seen for the first time in an “artificial nucleus” simulated on a sheet of graphene. The observation not only provides confirmation of long-held theoretical predictions, but could also pave the way for new kinds of graphene-based electronic devices, and for further research on basic physics.
Chemists have recently shown that conditions in space are capable of creating complex dipeptides—linked pairs of amino acids—that are essential building blocks shared by all living things. The discovery opens the door to the possibility that these molecules were brought to Earth aboard a comet or possibly meteorites, catalyzing the formation of proteins (polypeptides), enzymes and even more complex molecules, such as sugars, that are necessary for life.
Ancient languages hold a treasure trove of information about the culture, politics and commerce of millennia past. Yet, reconstructing them to reveal clues into human history can require decades of painstaking work. Now, scientists at the University of California, Berkeley, have created an automated “time machine,” of sorts, that will greatly accelerate and improve the process of reconstructing hundreds of ancestral languages.
The connection between poor sleep, memory loss and brain deterioration as we grow older has been elusive. But for the first time, scientists at the University of California, Berkeley, have found a link between these hallmark maladies of old age. Their discovery opens the door to boosting the quality of sleep in elderly people to improve memory.
Lawrence Berkeley National Laboratory and University of California, Berkeley researchers have discovered that the transcription factor protein TFIID co-exists in two distinct structural states, a key to genetic expression and TFIID’s ability to initiate the process by which DNA is copied into RNA.
Ever since he was a kid growing up in Germany, Holger Müller has been asking himself a fundamental question: What is time? That question has now led Müller, today an assistant professor of physics at the University of California, Berkeley to a fundamentally new way of measuring time. Taking advantage of the fact that, in nature, matter can be both a particle and a wave, he has discovered a way to tell time by counting the oscillations of a matter wave.
Researchers from Canada, California, and Poland have devised a straightforward way to test an intriguing idea about the nature of dark energy and dark matter. A global array of atomic magnetometers—small laboratory devices that can sense minute changes in magnetic fields—could signal when Earth passes through fractures in space known as domain walls. These structures could be the answer to the universe’s darkest mysteries.
