Mutations in same gene allow two different groups of humans to thrive at extreme altitudes
The high life is a lot harder than it sounds. Most people are accustomed to living at low elevations and struggle to breathe at high altitudes. But thin air isn’t a problem for the Quechua people of Peru, who have survived—and thrived—high in the Andes Mountains for more than 10,000 years.
Now, the authors of a new study published in
Science Advances
have
pinpointed a genetic variant that may have helped this population adapt to life at extraordinary heights
. Tibetans in the Himalayas possess a different mutation in the same gene, suggesting both groups independently evolved similar adaptat...

Clownfish might be counting their potential enemies' stripes
At least, that's what a group of researchers at the Okinawa Institute of Science and Technology Graduate University thinks. The team recently published a study in the journal Experimental Biology suggesting that Amphiphrion ocellaris, or clown anemonefish, may be counting. Specifically, the authors think the fish may be looking at the number of vertical white stripes on each other as well as other anemonefish as a way to identify their own species. Not only that — the researchers think that the fish are noticing the minutiae of other anemonefish's looks because of some fishy marine geopolitics. Questions, comments or tho...

Rare fossil reveals weird early tree
The earliest trees, from nearly 400 million years ago, are known mostly from fossils of their trunks; their leaves and canopy shapes have remained a mystery. A newly reported, 350-million-year-old tree found in Canada provides a vivid answer for one such primordial species: As if having a perpetual bad hair day,
a thick crown of spiky leaves stuck out perpendicularly from the trunk
. Scientists named the tree
Sanfordiacaulis densifolia
, after the owner of the New Brunswick quarry where they found five specimens. The fossils, amo...

Why NASA ’ s New Climate Satellite is Studying Clouds and Phytoplankton
If you’re trying to spot a phytoplankton, it pays to get exceedingly close. Among the smallest life forms inhabiting both fresh and marine water, phytoplankton can measure as little as one micrometer—or one millionth of a meter. But little things can have a big impact. Blooms of phytoplankton, which are actually a form of microalgae, can spread hundreds of square miles, sometimes doing disastrous damage to fisheries, beaches, drinking water supplies, and entire aquatic ecosystems. To track so sprawling a scourge, you want to stand at a distance—675 km (420 mi.) worth of distance. That’s the altitude...
