Phys.org / Why some antibiotics fail in the body—pH conditions can dramatically change how bacteria respond
When researchers test whether an antibiotic will work, they usually do so in a controlled laboratory environment. But when an infection happens inside the human body, things aren't so clean and tidy. New research from the ...
Phys.org / Researchers develop AI model that maps how genes work together in human cells
Scientists at the Icahn School of Medicine at Mount Sinai have created a new artificial intelligence (AI) model that helps reveal how genes function together inside human cells, offering a powerful new way to understand biology ...
Phys.org / Cell-by-cell sodium mapping reveals astrocytes are far less uniform than believed
The element sodium plays a key role in nervous system function. An international research team headed by the Institute of Neurobiology at Heinrich Heine University Düsseldorf (HHU) has now conducted a closer examination of ...
Phys.org / Do you know how cynical your friends are?
New research from Michigan State University finds that people often project their own levels of cynicism—the belief that people are only interested in themselves and aren't sincere—onto their friends and consistently underestimate ...
Phys.org / Macrocyclic host molecules observed working together on a surface
A collaborative research team from Kanazawa University and Kyoto University reports the successful visualization of how densely assembled macrocyclic host molecules cooperatively capture guest molecules on a surface. Using ...
Phys.org / Cell movement in the embryo: Zebrafish study shows that without keratin, nothing moves
Hair, nails, and horns, all made up of keratin, are some of the hardest and most resilient structures in animals. Inside zebrafish cells, keratin plays a distinct role, giving them the strength they need to move together ...
Phys.org / When noisy decision-making becomes a strategic advantage
A new study shows that apparently erratic or "sloppy" behavior in strategic situations is not necessarily a mistake. Under certain conditions, being less sensitive to one's own gains can become a long-term advantage.
Phys.org / Uncovering the link between epigenetic modifications and chromatin structure
Certain epigenetic modifications can directly control how genetic material is packed in the nucleus, RIKEN researchers have shown. This has important implications for our understanding of how genes are expressed in different ...
Phys.org / Is organic farming the solution to enhance natural drought resilience in crops?
A study led by researchers from the Department of Microbiology at the University of Malaga has revealed how organic farming—using natural substances and processes and avoiding the use of synthetic chemicals—can, in the long ...
Phys.org / Capturing an elusive step in molecular sandwich making
Since their discovery in the 1950s, metallocenes—chemical compounds where a metal atom sits "sandwiched" between two carbon rings—have been at the heart of organometallic chemistry research, finding applications in catalysis, ...
Phys.org / Developing seed atlas uncovers active genes tied to crop resilience and nutrition
Seeds like wheat, rice, and corn are at the center of the global food supply and provide most of the daily calories consumed worldwide. But despite their importance, scientists still do not fully understand many of the basic ...
Phys.org / NASA's Fermi glimpses power source of supercharged supernovae
LSU researchers helped uncover what may be the first clear detection of gamma rays from a superluminous supernova, using data from NASA's Fermi Gamma-ray Space Telescope—a breakthrough that offers new insight into the powerful ...
