A genomic tour-de-force reveals the last 5,000 years of horse history
The findings identify two new horse lineages that are now extinct and suggest that familiar traits such as speed were only selected for more recently in their history

Human influence on global droughts goes back 100 years, NASA study finds
The study, published in the journal Nature, compared predicted and real-world soil moisture data to look for human influences on global drought patterns in the 20th century.
Radical desalination approach may disrupt the water industry
If hypersaline brines are improperly managed, they can pollute both surface and groundwater resources.
Duck-billed dinosaurs: Evolutionary bursts led to weird and wonderful head crests
Called the 'sheep of the Mesozoic'as they filled the landscape in the Late Cretaceous period, hadrosaurs walked on their hind legs and were known for their powerful jaws with multiple rows of extremely effective teeth.
They also had hugely varied head display crests that signalled which species each belonged to
Nature's dangerous decline 'unprecedented,' species extinction rates 'accelerating'
"The overwhelming evidence of the IPBES Global Assessment, from a wide range of different fields of knowledge, presents an ominous picture," said IPBES Chair, Sir Robert Watson.
Plastic gets a do-over: Breakthrough discovery recycles plastic from the inside out: Scientists have made a next-generation plastic that can be recycled again and again into new materials of any color, shape, or form
Now a team of researchers at the U.S.
Close relatives can coexist: two flower species show us how
These findings offer a different perspective on theories surrounding co-existence, and suggest a new significance for plants' ability to self-fertilize..
Arctic warming will accelerate climate change and impact global economy
A new paper in Nature Communications reveals a combination of these factors has the potential to increase the long-term economic impact of climate change by just under $70 trillion, under mitigation levels consistent with current national pledges to cut carbon emissions (5% of the estimated total cost of climate change
An evolutionary rescue in polluted waters: How genetics, resources and a long-distant relative helped one lucky fish species adapt to extreme pollution
The exceptional survivor story of the Gulf killifish was one scientists at the University of California, Davis, Baylor University and their co-authoring colleagues wanted to unveil so they could learn more about what other species may need to adapt to drastically changed environments.
The minnow-like Gulf killifish are an important
Running may have made dinosaurs' wings flap before they evolved to fly: New evidence suggests that passive wing flapping may have arisen earlier than gliding flight
The findings, published in PLOS Computational Biology, provide new insights into the origin of avian flight, which has been a point of debate since the 1861 discovery of Archaeopteryx.
New 3-foot-tall relative of Tyrannosaurus rex
The newly named tyrannosauroid dinosaur -- Suskityrannus hazelae -- stood roughly 3 feet tall at the hip and was about 9 feet in length, the entire animal only marginally longer than the just the skull of a fully grown Tyrannosaurus rex, according to Sterling Nesbitt, an assistant professor with Department
Experimental device generates electricity from the coldness of the universe
An international team of scientists has demonstrated for the first time that it is possible to generate a measurable amount of electricity in a diode directly from the coldness of the universe..
Water found in samples from asteroid Itokawa: Up to half of Earth's ocean water may have come from impacts by asteroids
The team's findings suggest that impacts early in Earth's history by similar asteroids could have delivered as much as half of our planet's ocean water.
Harnessing sunlight to pull hydrogen from wastewater

Fracking: Earthquakes are triggered well beyond fluid injection zones: Computer model and field experiment data suggest a new link between subsurface injections and earthquake swarms
The results account for the observation that the frequency of human-made earthquakes in some regions of the country surpass natural earthquake hotspots..
