Phys.org / How flexible protein regions retain their function via motifs and chemical context
A new LMU study shows how proteins function reliably even without a stable 3D structure—and the crucial importance not only of short sequence motifs, but also of chemical characteristics.
Phys.org / Why swimmers still dive in: Research shows how UK communities navigate polluted waters
More than 7.5 million people immerse themselves in lakes, rivers, seas and lidos every year in the UK. But getting in the water means getting in pollution too for most outdoor swimmers. Raw sewage was discharged into UK waters ...
Medical Xpress / How the menstrual cycle can make or break an athlete's performance
As soccer's Women's Asian Cup continues in Australia, much analysis will inevitably focus on the physical: the speed of Mary Fowler, the power of Sarina Bolden, the endurance of Yui Hasegawa and Ellie Carpenter.
Phys.org / Ultrasound-based approach to delivering potent drugs into cancer cells shows promise in benchtop experiments
Engineers at Duke University have demonstrated a technique that uses microbubbles and ultrasound to help relatively large cancer drugs enter tumor cells and cause them to self-destruct. Dubbed "Sonoporation-assisted Precise ...
Medical Xpress / How the brain can selectively focus attention on one voice among others in a noisy environment
MIT neuroscientists have figured out how the brain is able to focus on a single voice among a cacophony of many voices, shedding light on a longstanding neuroscientific phenomenon known as the "cocktail party problem."
Phys.org / Comprehensive digital materials ecosystem can perform 'sanity check' to guide design
There is a near-infinite number of material candidates out there—and simply not enough time to hunker down in the lab and test them all. Thankfully, researchers have a variety of tools (such as AI) at their disposal to ...
Medical Xpress / Lost under stress? Study shows cortisol can scramble the brain's internal map
The stress hormone cortisol disrupts the brain's navigational system. It impairs the function of the grid cells that play a crucial role in orientation. This has been verified by researchers from Ruhr University Bochum, Germany, ...
Phys.org / Scientists confirm existence of molecule long believed to occur in oxidation
In the journal Science Advances, scientists in Sweden and the U.S. report the first-ever direct observation of a type of short-lived molecule that has shaped decades of thinking in atmospheric chemistry, combustion research ...
Medical Xpress / How the brain filters out 'expected' sounds: Orbitofrontal cortex study offers new insight
Humans and other animals gradually learn what sounds or other sensory cues in their surroundings are meaningful or potentially threatening. Via a process known as habituation, they gradually learn to ignore non-threatening ...
Phys.org / Urban park soil microbes reveal function–evolution trade-off
Urban parks are a vital component of urban ecosystems and provide distinctive habitats for soil microorganisms. Yet scientists have questioned whether—and how—the functional diversity and evolutionary potential of microbial ...
Phys.org / In a South Carolina swamp, researchers uncover secrets of firefly synchrony
In the middle of the old-growth forests of Congaree National Park in South Carolina, fireflies put on an otherworldly display every May. Thousands of male insects belonging to the species Photuris frontalis flash together ...
Medical Xpress / Research reveals how blood flow directs vessel health at the molecular level
How do blood vessels stay strong, flexible, and responsive to the body's changing need for oxygen and nutrients? The answer lies not only in biology—but also in physics. Researchers at Åbo Akademi University and the InFLAMES ...
