How humans develop larger brains than other apes

A new study is the first to identify how human brains grow much larger, with three times as many neurons, compared with chimpanzee and gorilla brains. The study identified a key molecular switch that can make ape brain organoids grow more like human organoids, and vice versa.

Cephalopods: Older than was thought?

Earth scientists have discovered possibly the oldest cephalopods in Earth's history. The 522 million-year-old fossils from Newfoundland (Canada) could turn out to be the first known form of these highly evolved invertebrate organisms. In that case, the find would indicate that the cephalopods evolved about 30 million years earlier than has been assumed.

Penguin hemoglobin evolved to meet oxygen demands of diving

Webbed feet, flipper-like wings and unique feathers all helped penguins adapt to life underwater. But by resurrecting two ancient versions of hemoglobin, a research team has shown that the evolution of diving is also in their blood, which optimized its capture and release of oxygen to ensure that penguins wouldn't waste their breath while holding it.

Tropical species are moving northward in U.S. as winters warm

Climate change is reducing the number of sub-freezing days over much of the American South, providing an opportunity for cold-sensitive tropical species -- mammals, reptiles, amphibians, insects, trees, shrubs and grasses -- to move northward, potentially displacing temperate species. Mosquitoes could bring infectious diseases farther north. The southern pine beetle is already moving north and devastating pine forests. While some may welcome manatees and sea turtles, few look forward to the spread of Burmese pythons.

Scientists stunned to discover plants beneath mile-deep Greenland ice

Scientists found frozen plant fossils, preserved under a mile of ice on Greenland. The discovery helps confirm a new and troubling understanding that the Greenland Ice Sheet has melted entirely during recent warm periods in Earth's history -- like the one we are now creating with human-caused climate change. The new study provides strong evidence that Greenland is more sensitive to climate change than previously understood -- and at risk of irreversibly melting.

Astronomers have discovered and studied in detail the most distant source of radio emission known to date. The source is a 'radio-loud' quasar -- a bright object with powerful jets emitting at radio wavelengths -- that is so far away its light has taken 13 billion years to reach us. The discovery could provide important clues to help astronomers understand the early Universe.

How fast is the universe expanding? Galaxies provide one answer

Among the methods astronomers have found to measure the expansion rate of the local universe, the Hubble constant, surface brightness fluctuations is potentially one of the most precise. Scientists have now published the first good SBF estimate of the Hubble constant, pegging it at 73.3 km/s/Mpc: in the ballpark of other measurements of the local expansion, including the gold standard using Type Ia supernovae. The new estimate highlights the mismatch with estimates from the early universe.

Woolly mammoths may have walked the landscape at the same time as the earliest humans in what is now New England, according to a new study.

This date may overlap with the arrival of the first humans in the Northeast, who are thought to have arrived around the same time.
