Genetic analysis uncovers the evolutionary origin of vertebrate limbs
Fish, mice and likely all modern-day vertebrates share genetic elements first used to develop the unpaired dorsal fin in ancient fish. They later copied these elements to produce paired appendages, like pelvic and pectoral fins, arms and legs. www.sciencedaily.com/releas...
Make way for the mini flying machines

Tiny floating robots could be useful in all kinds of ways, for example, to probe the human gut for disease or to search the environment for pollutants. In a step toward such devices, researchers describe a new marriage of materials, combining ultrathin 2-D electronics with miniature particles to create microscopic machines. www.sciencedaily.com/releas...
Democratizing science: Researchers make neuroscience experiments easier to share, reproduce
Democratizing science researchers make neuroscience experiments easier to share reproduce

Over the past few years, scientists have faced a problem: They often cannot reproduce the results of experiments done by themselves or their peers. This “replication crisis” plagues fields from medicine to physics, and likely has many causes. But one is undoubtedly the difficulty of sharing the vast amounts of data collected and analyses performed ...

These early humans survived a supervolcano eruption 74,000 years ago

Scientists analyzed the remains of two Paleolithic human campsites in South Africa (PP5-6 and VBB) to see whether there were dramatic changes after the Toba eruption 74,000 years ago in Sumatra. They found clear evidence that ash and glass from the eruption fell at these sites, and yet human habitation remained uninterrupted. (credit: Nature)

Chain reaction of fast-draining lakes poses new risk for Greenland ice sheet
Crop 63
A growing network of lakes on the Greenland ice sheet has been found to drain in a chain reaction that speeds up the flow of the ice sheet, threatening its stability.  www.cam.ac.uk/research/news...
