A new method boosts wind farms' energy output, without new equipment      (via sciencedaily.com) 

Engineers have developed a method to increase wind farms' energy output. Whereas individual turbines are typically controlled separately, the new approach models the wind flow of the entire collection of turbines and optimizes the control of individual units.

All the better to better eat you with -- dinosaurs evolved different eye socket shapes to allow stronger bites      (via sciencedaily.com) 

Large dinosaur predators, such as Tyrannosaurus rex, evolved different shapes of eye sockets to better deal with high bite forces, new research has shown.

Hubble sees red supergiant star Betelgeuse slowly recovering after blowing its top      (via sciencedaily.com) 

The star Betelgeuse appears as a brilliant, ruby-red, twinkling spot of light in the upper right shoulder of the winter constellation Orion the Hunter. But when viewed close up, astronomers know it as a seething monster with a 400-day-long heartbeat of regular pulsations. This aging star is classified as a supergiant because it has swelled up to an astonishing diameter of approximately 1 billion miles. If placed at the center of our solar system it would reach out to the orbit of Jupiter. The star's ultimate fate is to explode as a supernova.

Safe havens for cooperation      (via sciencedaily.com) 

Whether networks with a high level of cooperation emerge in a community depends on how quickly individuals leave -- for example, because they are exploited by others. Researchers investigated this problem by modeling a well-known cooperation game. They consider a spatial network, where players can relocate between different patches if they judge the local conditions to be unfavorable.

Astronomers confirm star wreck as source of extreme cosmic particles      (via sciencedaily.com) 

NASA's Fermi Gamma-ray Space Telescope confirms one supernova remnant as a launch site for some of our galaxy's highest-energy protons.

First stars and black holes      (via sciencedaily.com) 

Just milliseconds after the universe's Big Bang, chaos reigned. Atomic nuclei fused and broke apart in hot, frenzied motion. Incredibly strong pressure waves built up and squeezed matter so tightly together that black holes formed, which astrophysicists call primordial black holes. Did primordial black holes help or hinder formation of the universe's first stars, eventually born about 100 million years later?

One more clue to the Moon's origin      (via sciencedaily.com) 

Researchers discover the first definitive proof that the Moon inherited indigenous noble gases from the Earth's mantle. The discovery represents a significant piece of the puzzle towards understanding how the Moon and, potentially, the Earth and other celestial bodies were formed.

Extreme heat and drought events require more systematic risk assessment      (via sciencedaily.com)     Original source 

Simultaneous extreme heat and drought events have consequences in a variety of areas -- for example the economy, health and food production. In addition, due to complex socio-economic connections, such extreme events can cause knock-on effects, researchers have shown. More systematic risk assessments are needed to make affected regions more resilient.

Prehistoric podiatry: How dinos carried their enormous weight      (via sciencedaily.com) 

Scientists have cracked an enduring mystery, discovering how sauropod dinosaurs -- like Brontosaurus and Diplodocus -- supported their gigantic bodies on land.

Building on the moon and Mars? You'll need extraterrestrial cement for that      (via sciencedaily.com) 

Researchers are exploring ways to use clay-like topsoil materials from the moon or Mars as the basis for extraterrestrial cement that could be used by astronauts to create building materials for life in outer space. Scientists have converted simulated lunar and Martian soils into geopolymer cement, which is considered a good substitute for conventional cement.

Local renewable energy employment can fully replace U.S. coal jobs nationwide, study finds      (via sciencedaily.com) 

Across the United States, local wind and solar jobs can fully replace the coal-plant jobs that will be lost as the nation's power-generation system moves away from fossil fuels in the coming decades, according to a new study.

How a harmful fungus renders its host plant defenseless      (via sciencedaily.com) 

The fungus Ustilago maydis attacks corn and can cause significant damage to its host. To do this, it first ensures that the plant offers little resistance to the infection. The surgical precision it applies is shown by a new study.

Nearly a hundred genes have been lost during the woolly mammoth's evolution      (via sciencedaily.com) 

A new study shows that 87 genes have been affected by deletions or short insertions during the course of the mammoth's evolution. The researchers note that their findings have implications for international efforts to resurrect extinct species, including the woolly mammoth.

Evidence that giant meteorite impacts created the continents      (via sciencedaily.com)     Original source 

New research has provided the strongest evidence yet that Earth's continents were formed by giant meteorite impacts that were particularly prevalent during the first billion years or so of our planet's four-and-a-half-billion year history.

CT scanner captures entire woolly mammoth tusk      (via sciencedaily.com) 

Researchers successfully captured CT images of an entire woolly mammoth tusk. Researchers were able to do a full scan of the tusk in its entirety -- or in toto -- using a newer clinical CT scanner. The new technology allows for large-scale imaging without having to do multiple partial scans.
