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. ...

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 ...

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. ...

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 ...

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 ...

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 ...

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, ...

A massive global genetics study is reshaping how we understand mental illness--and why diagnoses so often pile up. By analyzing genetic data from more than six million people, researchers uncovered deep genetic connections across 14 psychiatric ...

Scientists have precisely measured two unstable atomic nuclei that play a crucial role in explosive X-ray bursts on neutron stars. The results reveal faster nuclear reactions than previously thought, reshaping how we understand element formation in . ...

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 ...
