Phys.org / When a SpaceX rocket crashes into the moon, scientists will be watching
On Aug. 5, 2026, an abandoned piece of space junk is predicted to crash into the moon near a spot called Einstein Crater. Astronomers will be watching because the collision and aftermath may be visible from Earth.
Tech Xplore / Soft exosuit shows motor-free path to wearable walking assistance
Researchers in China have unveiled a new robotic exosuit driven entirely by soft artificial muscles instead of traditional motors. This technology could make it easier for older adults, injured patients or factory workers ...
Phys.org / Why some human brains can outlast other soft tissues after death
Why do some brains survive long after death when most other soft tissue decays? That's the question a research team led by Alexandra Morton-Hayward at the University of Oxford set out to answer.
Medical Xpress / A new plan for healthy aging starts before we're born
Most of us would like to hang around on the planet for as long as possible, and thankfully, lifespans in many countries are increasing. Scientists are also developing a new field known as longevity medicine, which aims to ...
Phys.org / Giving bees a probiotic diet could help protect them from extreme temperatures
Honeybees do not like cold weather. When temperatures dip, they can become sluggish and unable to fly. But no matter the conditions in the outside world, they try to keep their hives close to a comfortable 34°C–36°C (93°F–97°F). ...
Phys.org / New super strong glue grips non-stick surfaces and wipes away easily
In a research lab at the University of Tokyo, scientists have developed a new kind of glue. It's incredibly strong and highly stretchable, yet it washes away completely with a little alcohol.
Medical Xpress / New study sheds light on how Epstein-Barr virus may contribute to multiple sclerosis
Multiple sclerosis (MS) is a chronic autoimmune disorder that attacks the central nervous system. For years, Epstein-Barr virus (EBV) has been strongly linked to MS, as nearly every person diagnosed with the condition shows ...
Phys.org / Tooth enamel reveals the origins of African slaves buried on St Helena
In the mid-19th century, the remote island of St. Helena, located about 1,200 miles (1,900 kilometers) off the southwestern coast of Africa, became a receiving point for thousands of enslaved Africans rescued from illegal ...
Phys.org / Scientists invent new board games to reveal how we tackle the unknown
Playing board games can be fun, challenging, infuriating and a great way to pass the time. They can also help scientists understand how we solve new problems.
Phys.org / A new record holder for the world's oldest amber discovered in China
Paleontologists in China have discovered the oldest chemically verified amber ever found, dating to 385 million years ago. That's approximately 140 million years before dinosaurs roamed Earth. The previous record holder was ...
Phys.org / Crab-dug tunnels boost methane-eating microbes in coastal wetlands, study finds
Wetlands are a significant producer of methane, a greenhouse gas more potent than carbon dioxide. Yet not all of it escapes into the atmosphere. One reason is crabs. A study published in the journal Environmental Science ...
Phys.org / T. rex babies were born ready to run and feed themselves
Tyrannosaurus rex was a giant of the prehistoric world, standing up to 13 feet (4 meters) tall and weighing around 9 tons (8 tonnes). So you might expect that its hatchlings were also a considerable size.
Phys.org / Scientists recover sub-Saharan Africa's oldest ancient animal DNA
Ancient DNA can be a powerful tool for helping us reconstruct the long-dead past. Most surviving genetic material comes from the bones and teeth of animals that lived in cold environments, where freezing temperatures help ...
Phys.org / A new smart coating could improve the cleanup of nuclear wastewater
Scientists in China have developed a smart coating that could make it easier to remove tritium (a radioactive form of hydrogen) from nuclear power plant wastewater.
Phys.org / Why we may still be choosing our friends like it's the Stone Age
Choosing friends may involve more than clicking with others who share our interests or outlooks. According to new research, people may select friends based on traits that made them valuable survival partners in our evolutionary ...
