Although we weren’t here to observe the birth of our own solar system, astronomers have developed a relatively informed picture of how it likely happened, based on observations of our present-day home and the infant planets forming around other stars. But every so often, something throws a wrench in our theories, and that may have just happened — researchers have discovered interesting new properties of Saturn and its moons that contradict our current models for how the solar system ...read more

Buried among 77 other people from her village in western Sweden are the bones of a 20 year-old woman. Now an analysis of DNA extracted from her teeth reveals what likely killed her. An international team of researchers has discovered the woman, who died some 5,000 years ago, had the oldest known case of the plague. The finding suggests the world’s first plague epidemic took out her community and vast swaths of the Neolithic farming population in Europe. If confirmed, the notorio ...read more

Although 54 percent of adults in the United States have registered as organ donors, just one in three people die in a way that allows for organ donation. That leaves more than 100,000 people in the United States waiting for a transplant. Many will die waiting. Because demand for organs outpaces supply and probably always will, researchers have looked to xenotransplantation — placing animal organs into human bodies — as an alternative. However, getting to the point where xenotra ...read more

Moon-bound Tomorrow, at about 1:30 p.m. EST (2:30 a.m. on Dec. 8 local time), China’s robotic Chang'e-4 mission will launch on a Long March 3B rocket, headed for the lunar surface. After launching, the spacecraft will spend 27 days traveling to the moon. Upon arrival at our rocky satellite, an accompanying lander, which doubles as a rover, will descend towards the surface. The craft will touch down in the Von Kármán Crater in the South Pole‐Ait ...read more

Human tissues on a chip are headed into space. Tissue chips contain a small network of cells that work like real human organs, and are a safe, compact way for scientists to study the human body. SpaceX's Dragon resupply mission launched from Florida yesterday and is currently rocketing toward the International Space Station (ISS). On board are a few dozen chips designed to mimic the immune system — like the kidney-on-a-chip shown here. The missions is led by the National Institu ...read more

If orbiting just 4 million miles from your fiery host star wasn’t bad enough, things might have just gotten even worse. New research shows that stars emitting high levels of ultraviolet (UV) radiation could strip the atmospheres of their ultra-close exoplanets. While observing gas giants that orbit exceptionally close to their host stars, astronomers found that those bombarded with radiation were losing helium from their atmospheres. These results, which were published in multiple st ...read more

A new study shows the historical dates of key archaeological sites associated with Europeans’ first contact with indigenous communities are off by nearly 100 years. The discovery “dramatically rewrites” the history of northeastern North America, researchers report today in the journal Science Advances. “It will really change how we understand the history ... of this entire period, just before and during early contact with European civilization,” Sturt Manning, a pa ...read more

For the first time, researchers have identified blubber, and other soft tissue, preserved in an Early Jurassic ichthyosaur. The new interpretation of the 180-million-year-old fossil suggests that the extinct marine reptiles were warm-blooded. Ichthyosaurs swam the Mesozoic Era seas and were roughly contemporary with dinosaurs. They are often compared with modern toothed whales, particularly porpoises (though at least one ichthyosaur species attained blue whale-like size). Many paleont ...read more

Scientists have announced a breakthrough in stem cell research that could have major implications for medical treatments that involve regenerating human cells. And their discovery came from an unlikely source: royal jelly. It's the same substance honey bees use to turn a common bee larvae into a queen. Royal Jelly A queen bee starts her life just like any other bee – a larva in the honey bee hive, taken care of by her siblings. But when it’s time for a new queen, this larva is pulled ...read more

Nearly 25 percent of the world is anemic. Now researchers have created a smartphone app that can detect the condition with a photo. The new tech could mean diagnosing and monitoring the blood disorder without a finger poke or blood draw. “This is a way for anyone to screen themselves for anemia and all they have to do is download an app,” said Wilbur Lam, a bioengineer and pediatric hematologist at Georgia Tech and Emory University in Atlanta, who led the new research. “It doe ...read more
