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
