Phys.org / 'Speed scanner' can test thousands of plant gene switches at once
Agriculture, from the outset, has been made possible by humans tweaking the genes of plants to make them grow faster, produce more of what we want, and survive drought, pests, and infection. For millennia, we did it with ...
Phys.org / Light-controlled cholesterol 'look-alikes' point toward smarter drug delivery
High levels of cholesterol are linked to heart disease, stroke, and many other health problems. However, this complex and vital fatty, water insoluble molecule—a lipid—is found in every cell of the body and is not all ...
Phys.org / Enzyme shape-shifting captured in real time during catalysis
Researchers have captured real-time "molecular movies" showing how an enzyme changes shape during catalysis. The study was published in Nature Communications.
Phys.org / Improved tracer labeling expands PET imaging possibilities
Imagine being able to watch organs and tissues work in real time. That's the power of Positron Emission Tomography (PET) imaging, a technology that gives physicians and researchers a window into cellular processes.
Phys.org / Key proteins reveal how evolution of locomotion shapes bone remodeling processes
An international collaboration study reveals how evolution and locomotion patterns, such as bipedalism, shaped bone structures through proteins present in the bone matrix. The findings of the study, led by researchers from ...
Phys.org / Cell death discovery could aid cancer treatments
La Trobe researchers have made a discovery about the way dying cells are cleared from our bodies, which could have important impacts on recovery from diseases including cancer infection and inflammatory diseases.
Phys.org / Public seed banks can fast-track corn quality research
University of Illinois Urbana-Champaign corn breeders know profitability is about more than yield. By tweaking kernel composition, they can tailor corn for lucrative biotech applications, industrial products, overseas markets, ...
Phys.org / Ancient hunter-gatherer DNA may explain why some people live to 100 years or more
Our hunter-gatherer ancestors have given us many things. They passed down mastery of fire for cooking and early survival technologies, such as stone tools. They may also have given us the secret to a long life. A new study ...
Phys.org / Physicists push superconducting diodes to high temperatures
For the first time, researchers in China have demonstrated a high-temperature superconducting diode effect, which allows a supercurrent to flow in both directions. Published in Nature Physics, the team's result could help ...
Phys.org / Saturn's rings extend further above and below the ring plane, forming a 'halo'
The Cassini probe took its final orbits, referred to as the Grand Finale Orbits (GFOs), in 2017, before launching itself into Saturn's atmosphere. During these GFOs, the probe collected samples of dust above and below Saturn's ...
Phys.org / How a new diet of penguins is changing puma behavior and social lives in Patagonia
Penguins in the coastal steppes of Argentina have a new enemy to worry about: the increasing numbers of pumas in Monte León National Park (MLNP). These powerful mountain cats were once on the brink of disappearing from this ...
Phys.org / Subtle twist in materials prompts surprising electromagnetic behavior
Materials react differently to electric and magnetic fields, and these reactions are known as electromagnetic responses. In many solid materials, unusual electromagnetic responses have been known to only emerge when specific ...
