Skin is remarkably resistant to tearing and a team of researchers from the Univ. of California, San Diego and the Lawrence Berkeley National Laboratory now have shown why. Using powerful x-ray beams and electron microscopy, researchers made the first direct observations of the micro-scale mechanisms that allow skin to resist tearing.
Few among us may know what magnetic domains are, but we make use of them daily when we email files, post images or download music or video to our personal devices. Now a team of researchers at Lawrence Berkeley National Laboratory has found a new way of manipulating the walls that define these magnetic domains and the results could one day revolutionize the electronics industry.
An international team of nuclear physicists announced the first scientific results from the Cryogenic Underground Observatory for Rare Events (CUORE) experiment. CUORE is designed to confirm the existence of the Majorana neutrino, which scientists believe could hold the key to why there is an abundance of matter over antimatter. Or put another way: why we exist in this universe.
A great deal of public attention in the past couple of years has been showered on complexes of bacterial proteins known as “CRISPR-Cas” for their potential use as a tool for editing DNA. Now, researchers with the Lawrence Berkeley National Laboratory are reporting that CRISPR-Cas complexes could also serve as an engineering tool for RNA, the molecule that translates DNA’s genetic instructions into the production of proteins.
Scientists at Lawrence Berkeley National Laboratory have published the world’s largest set of data on the complete elastic properties of inorganic compounds, increasing by an order of magnitude the number of compounds for which such data exists.
Tropical forests play major roles in regulating Earth’s climate, but there are large uncertainties over how they’ll respond over the next 100 years as the planet’s climate warms. An expansive new project led by scientists from Lawrence Berkeley National Laboratory aims to bring the future of tropical forests and the climate system into much clearer focus.
When weighing the pluses and minuses of your skin add this to the plus column: Your skin, like that of all vertebrates, is remarkably resistant to tearing. Now, a collaboration of researchers at Lawrence Berkeley National Laboratory and the Univ. of California, San Diego, has shown why.
In the first study of its kind, scientists at Lawrence Berkeley National Laboratory quantitatively show that electric vehicles (EVs) will meet the daily travel needs of drivers longer than commonly assumed. Many drivers and much prior literature on the retirement of EV batteries have assumed that EV batteries will be retired after the battery has lost 20% of its energy storage or power delivery capability.
In the on-going search for a better understanding of how the brain and central nervous system develop, a potentially powerful new tool could soon be available. Researchers at Lawrence Berkeley National Laboratory have discovered a light-sensitive opsin protein that plays a surprising and possibly critical role in neuron maturation and circuit formation.
There’s a carbon showdown brewing in the Arctic as Earth’s climate changes. On one side, thawing permafrost could release enormous amounts of long-frozen carbon into the atmosphere. On the opposing side, as high-latitude regions warm, plants will grow more quickly, which means they’ll take in more carbon from the atmosphere. Whichever side wins will have a big impact on the carbon cycle and the planet’s climate.
A means by which the removal of carbon dioxide from coal-fired power plants might one day be done far more efficiently and at far lower costs than today has been discovered by a team of researchers with the Lawrence Berkeley National Laboratory. By appending a diamine molecule to the sponge-like solid materials known as MOFs, the researchers were able to more than triple the carbon dioxide-scrubbing capacity of the MOFs.
If advanced biofuels are to replace gasoline, diesel and jet fuel on a gallon-for-gallon basis at competitive pricing, we’re going to need a new generation of fuel crops. Researchers with the Joint BioEnergy Institute have demonstrated the power of a new ally in this effort: proteomics.
Scientists from Lawrence Berkeley National Laboratory have uncovered new clues about the risk of cancer from low-dose radiation, which in this research they define as equivalent to 100 millisieverts or roughly the dose received from ten full-body CT scans. They studied mice and found their risk of mammary cancer from low-dose radiation depends a great deal on their genetic makeup.
When it comes to boiling water, is there anything left for today’s scientists to study? The surprising answer is, yes, quite a bit. How the bubbles form at a surface, how they rise up and join together, what are the surface properties, what happens if the temperature increases slowly versus quickly. While these components might be understood experimentally, the mathematical models for the process of boiling are incomplete.
Researchers with the Energy Biosciences Institute have found a way to increase the production of fuels and other chemicals from biomass fermented by yeast. By introducing new metabolic pathways into the yeast, they enable the microbes to efficiently ferment cellulose and hemicellulose, the two major families of sugar found in the plant cell wall, without the need of environmentally harsh pre-treatments or expensive enzyme cocktails.
As everyone who lives in the San Francisco Bay Area knows, the Earth moves under our feet. But what about the stresses that cause earthquakes? How much is known about them? Until now, our understanding of these stresses has been based on macroscopic approximations.
A powerful genome editing tool may soon become even more powerful. Researchers with the Lawrence Berkeley National Laboratory have unlocked the key to how bacteria are able to “steal” genetic information from viruses and other foreign invaders for use in their own immunological memory system.
Scientists have captured the first detailed microscopy images of ultra-small bacteria that are believed to be about as small as life can get. The existence of ultra-small bacteria has been debated for two decades, but there hasn’t been a comprehensive electron microscopy and DNA-based description of the microbes until now.
Scientists have observed an increase in carbon dioxide’s greenhouse effect at the Earth’s surface for the first time. The researchers, led by scientists from Lawrence Berkeley National Laboratory, measured atmospheric carbon dioxide’s increasing capacity to absorb thermal radiation emitted from the Earth’s surface over an eleven-year period at two locations in North America.
In March, when researchers flip the switch to the world’s largest, most powerful particle accelerator, scientists from all over the world will be watching. Physicists expect the refurbished, higher-energy Large Hadron Collider (LHC) will build on the 2012 discovery of the Higgs particle and crack open even more mysteries of the universe.
When electronic states in materials are excited during dynamic processes, interesting phenomena such as electrical charge transfer can take place on quadrillionth-of-a-second, or femtosecond, timescales. Numerical simulations in real time provide the best way to study these processes, but such simulations can be extremely expensive.
Imagine thousands of copies of a single protein organizing into a coat of chainmail armor that protects the wearer from harsh and ever-changing environmental conditions. That is the case for many microorganisms. In a new study, researchers with Lawrence Berkeley National Laboratory have uncovered key details in this natural process that can be used for the self-assembly of nanomaterials into complex 2- and 3-D structures.
Lawrence Berkeley National Laboratory battery scientist Nitash Balsara has worked for many years trying to find a way to improve the safety of lithium-ion batteries. Now he believes he has found the answer in a most unlikely material: a class of compounds that has mainly been used for industrial lubrication.
Metamaterials offer tantalizing future prospects such as high-resolution optical microscopes and superfast optical computers. To realize the vast potential of metamaterials, however, scientists will need to hone their understanding of the fundamental physics behind them. This will require accurately predicting nonlinear optical properties.
Univ. of California, Berkeley scientists have found the mechanism by which titanium, prized for its high strength-to-weight ratio and natural resistance to corrosion, becomes brittle with just a few extra atoms of oxygen. The discovery has the potential to open the door to more practical, cost-effective uses of titanium in a broader range of applications.
