Phys.org / Not a cheetah: Ancient DNA reveals the surprising Arctic life of extinct North American cat
A new study led by researchers at the University of California, Santa Cruz, has overturned decades of assumptions about Miracinonyx trumani, the extinct predator popularly known as the American cheetah. By analyzing nuclear ...
Phys.org / Pair of white dwarfs locked in 6-minute orbit might one day be observed by gravitational waves
Current gravitational-wave observatories aren't sensitive enough to capture the gravitational waves of binary stars. They can only see the gravitational chirps of black holes just as they are merging. But that will change ...
Medical Xpress / Diabetes drug metformin could be repurposed to help slow aging mechanisms
Metformin, a widely prescribed, safe and inexpensive drug for type 2 diabetes, is a first-line treatment that lowers blood sugar and improves the body's response to insulin. The drug appears to trick cells into sensing an ...
