Scientists may have cracked the case of whether a seven-million-year-old fossil could walk upright. A new study found strong anatomical evidence that Sahelanthropus tchadensis was bipedal, including a ligament attachment seen only in human ancestors. Despite its ape-like
The brain constantly blends split-second reactions with slower, more thoughtful processing, and new research shows how it pulls this off. Scientists discovered that brain regions operate on different internal clocks and rely on white matter connections to share information
Scientists have developed molecular devices that can switch roles, behaving as memory, logic, or learning elements within the same structure. The breakthrough comes from precise chemical design that lets electrons and ions reorganize dynamically. Unlike conventional
Scientists and physicians can better assess precision genome editing technology using a new method made public today by St. Jude Children's Research Hospital. Significant amounts of time and resources spent improving CRISPR gene editing technology focus on identifying small
Using the Anglo-Australian Telescope (AAT), astronomers have observed a nearby galactic globular cluster known as NGC 6569. Results of the observational campaign, published December 22 on the arXiv preprint server, indicate that this galaxy is actively losing stars through
Researchers have uncovered thousands of preserved metabolic molecules inside fossilized bones millions of years old, offering a surprising new window into prehistoric life. The findings reveal animals’ diets, diseases, and even their surrounding climate, including evidence of
Time-restricted eating has been widely promoted as a simple way to boost metabolic health, but new research paints a more complicated picture. When calorie intake stayed the same, an eight-hour eating window did not improve insulin sensitivity or cardiovascular markers. What
As spinal cord injuries increasingly affect older adults, new research reveals a surprising pattern in recovery. The study shows that aging does not appear to slow the healing of nerves themselves, with older patients regaining strength and sensation at rates similar to younger
A one-dose oral drug called zoliflodacin has proven highly effective against gonorrhoea in a major international trial. The pill matched the success of current treatments while avoiding injections and complex dosing. As antibiotic resistance spreads, this new option could make
Researchers discovered that clogged brain “drains” show up early in people at risk of Alzheimer’s disease. These blockages, easily seen on standard MRI scans, are tied to toxic protein buildup linked to memory loss and cognitive decline. In some cases, they may signal
