Phys.org / Chromatin tracking reveals two motion modes that help control gene expression
Gene expression is controlled, in part, by the interactions between genes and regulatory elements located along the genome. Those interactions depend on the ability of chromatin—a mix of DNA and proteins—to move around within ...
Phys.org / Bees can detect viruses in food sources, but don't necessarily avoid them
The ability to detect viruses and other harmful pathogens is highly advantageous for animals, as it can guide their behavior and prevent them from illness, and—in severe cases—death. When it comes to species that live in ...
Phys.org / A simple filter swap could advance marine eDNA biomonitoring
Researchers at Aarhus University have demonstrated that a simple adjustment to water filtration methods can dramatically improve the detection of marine animal DNA when using advanced, PCR-free sequencing. This methodological ...
Medical Xpress / Creatine is claimed to benefit body and mind: The potential benefits and limitations of the popular supplement
Creatine, a compound often associated with gym-goers and athletes, has long been touted as a performance-enhancing supplement. But beyond the hype, what does science actually reveal about its effects on the body and mind?
Medical Xpress / One missing metabolic step can turn cancer's DNA-copying machinery into a lethal weakness
Loss of an enzyme necessary for a process called lipoylation disrupts the way cancer cells copy their DNA, increasing their vulnerability to a class of anticancer drugs known as PARP inhibitors, a study led by UT Southwestern ...
Medical Xpress / X-linked liver enzyme may explain why women and men process cholesterol differently
A new study from Karolinska Institutet shows that an enzyme in the liver may partly explain sex differences in the body's handling of cholesterol and the risk of developing atherosclerosis. The research, published in Nature ...
Science X / That split-second panic when something rushes toward you may hinge on one deceptively simple sound cue
Those jolts of terror that seem to occur whenever a noise comes closer? While we assume that this is an age-old survival reaction, modern revelations show that there may be an easier explanation for what's occurring.
Medical Xpress / FDA grants expanded access to the pancreatic cancer drug daraxonrasib
The U.S. Food and Drug Administration (FDA) has granted expanded access for the use of an experimental pancreatic cancer drug, daraxonrasib. This means the drug will be available for early access to those who previously received ...
Medical Xpress / Lithium not working? Large-scale study highlights favorable treatment strategies for bipolar disorder
Bipolar disorder is a mental health condition estimated to affect between 1% and 3% of people worldwide. Its main symptoms include extreme mood swings, ranging from periods of high activity and emotional high (i.e., mania) ...
Phys.org / What's stopping kids from learning useful skills? Short answer: Exams
Across Africa and beyond, education systems are shifting to curricula designed to build critical thinking and problem-solving skills.
Phys.org / A leading journal finds that AI is flooding academic publishing with lower quality work
Artificial intelligence can undoubtedly help scientists with their academic papers by summarizing research and helping to improve writing. However, one downside is that it has led to a wave of poorly written submissions and ...
Phys.org / Deadly droughts and floods wipe out young California salmon en route to Pacific
Salmon are becoming river "ghosts" as brutal droughts and violent floods cause unprecedented losses on their treacherous journey to the Pacific Ocean, scientists say. A study led by the University of Essex; NOAA Fisheries; ...
