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

Did Sahelanthropus, which lived 7 million years ago, walk on two legs like a modern human? It's complicated
A new study reveals that bacteria can survive antibiotic treatment through two fundamentally different "shutdown modes," not just the classic idea of dormancy. The paper is published in the journal Science Advances.
Angiosperms, also known as flowering plants, represent the most diverse group of seed plants, and their origin and evolution have long been a central question in plant evolutionary biology. Whole-genome duplication (WGD), or polyploidization, is widely recognized as a key
In recent decades, scientists have debated whether a seven-million-year-old fossil was bipedal—a trait that would make it the oldest human ancestor. A new analysis by a team of anthropologists offers powerful evidence that Sahelanthropus tchadensis—a species discovered in the
For the first time, scientists have reconstructed the ancient genomes of human betaherpesvirus 6A and 6B (HHV-6A/B) from archaeological human remains more than two millennia old. The study, led by the University of Vienna and University of Tartu (Estonia) and published in
Every day, millions of people use thermal paper without thinking about it. Receipts, shipping labels, tickets, and medical records all rely on heat‑sensitive coatings to make text appear. More specifically, heat triggers a reaction between a colorless dye and a "developer,"
A fossil belonging to an ancient hominin that lived seven million years ago bears the hallmarks of bipedalism, according to a new study
