Phys.org / Neanderthals may have used birch tar for its anti-bacterial properties, experiments suggest
Neanderthals probably used birch tar for multiple functions, including treating their wounds, according to a study published in the open-access journal PLOS One by a team of researchers led by Tjaark Siemssen of the University ...
Phys.org / How DICER cuts microRNAs with single-nucleotide precision
A research team from The Hong Kong University of Science and Technology (HKUST) has made an advance in understanding the molecular machinery of RNA silencing. The team uncovered how the human enzyme DICER achieves highly ...
Phys.org / Researchers uncover gut-liver serotonin pathway that limits nanoparticle and viral delivery
A new study has for the first time elucidated the gut-liver immune regulatory axis jointly maintained by intestinal commensal bacteria and the intestinal endocrine system, and uncovered the fundamental mechanism underlying ...
Phys.org / Sea levels around Africa are rising faster than the global average: What's behind this alarming trend
For over three decades, satellites orbiting Earth have measured the height of the ocean surface with remarkable precision. These measurements are crucial because changes in ocean height are one of the clearest indicators ...
Medical Xpress / What to know about fatty liver disease and why it's so common
Fatty liver disease is when too much fat builds up in the liver. The liver is the body's filter. It helps clean the blood, store energy and process nutrients. If too much fat stays in the liver, it can harm the organ and ...
Medical Xpress / Safeguarding older adults: Rethinking nursing home emergency preparedness
When disasters strike, nursing homes face uniquely high stakes. Residents often depend on power, medications, mobility assistance, and continuous care—all of which can be disrupted by hurricanes, wildfires, or other emergencies. ...
Phys.org / Palm oil, cocoa, coffee… Who's going to tend to tomorrow's large tropical plantations?
Palm oil plantations, for one, are increasingly struggling with the sector's declining attractiveness, which has hardly changed since the colonial era.
Medical Xpress / Could a gut microbe influence muscle strength?
The trillions of microbes living in the human gut are increasingly recognized as important partners in human health. Scientists have linked the gut microbiome to several aspects of health, from metabolism and immunity to ...
Tech Xplore / Why you may be paying more than you need to for digital subscriptions
The way we watch TV, listen to music, order groceries and take photos has changed in the past decade or so. For many of us, all of these activities involve a monthly payment.
Dialog / Why a better-performing developing brain may be a better-tuned brain
An influential hypothesis in neuroscience is that the brain may operate near criticality, a transition zone between subcritical dynamics, associated with excessive inhibition, and super-critical dynamics, associated with ...
Medical Xpress / Physical activity reshapes neural connectivity and makes the brain more resilient after childhood trauma
New research indicates that the long-term neurological impact of childhood trauma is not permanently etched onto the brain. An analysis of brain communication patterns in a group of individuals who have experienced childhood ...
Phys.org / Why some regions are winning the fight against groundwater depletion
For half the world's population, the water in their drinking glasses comes from below them. Groundwater also supplies 40% of global irrigation projects. Alarmingly, more than a third of the planet's aquifers, or groundwater ...
