Meteorite crater discovered in French winery      (via sciencedaily.com) 

Countless meteorites have struck Earth in the past and shaped the history of our planet. It is assumed, for example, that meteorites brought with them a large part of its water. The extinction of the dinosaurs might also have been triggered by the impact of a very large meteorite. It turns out that the marketing 'gag' of the 'Domaine du Météore' winery is acutally a real impact crater. Meteorite craters which are still visible today are rare because most traces of the celestial bodies have long since disappeared again.

James Webb spots super old, massive galaxies that shouldn't exist      (via sciencedaily.com) 

A team of international researchers have identified six candidate galaxies that existed roughly 500 to 700 million years after the Big Bang and are about as big as the modern Milky Way Galaxy -- a feat that scientists didn't think was possible.

Sheep can benefit urban lawn landscapes and people      (via sciencedaily.com) 

About 25 woolly sheep who seasonally -- for the past two years -- leave barns to nibble on lawns at various central campus locations, are doing much more than mowing, fertilizing and improving the ecosystem. The sheep also are improving people's mental health.

Researchers map mosquito cells that may help the insects choose tastiest humans      (via sciencedaily.com) 

In a bid to understand why mosquitoes may be more attracted to one human than another, researchers say they have mapped specialized receptors on the insects' nerve cells that are able to fine-tune their ability to detect particularly 'welcoming' odors in human skin.

Noble false widow spider found preying on pygmy shrew      (via sciencedaily.com) 

Scientists have published the first record of a noble false widow spider feeding on a pygmy shrew, a species of tiny mammal protected in Ireland. The pygmy shrew -- a protected mammal -- was captured on spider's web on a bedroom window, then paralyzed and hoisted to its doom by the invasive spider.

Geckos know their own odor      (via sciencedaily.com) 

Geckos can use their tongue to differentiate their own odor from that of other members of their species, as researchers have shown in a new experimental study. The findings show that geckos are able to communicate socially, meaning that they are more intelligent than was previously assumed.

How the fastest fish hunts its prey      (via sciencedaily.com) 

Scientists have designed a novel electronic tag package incorporating high-tech sensors and a video camera in order to document a detailed view of exactly how sailfish behave and hunt once they are on their own and out of view of the surface.

Kangaroo fecal microbes could reduce methane from cows      (via sciencedaily.com) 

Baby kangaroo feces might help provide an unlikely solution to the environmental problem of cow-produced methane. A microbial culture developed from the kangaroo feces inhibited methane production in a cow stomach simulator. After researchers added the baby kangaroo culture and a known methane inhibitor to the simulated stomach, it produced acetic acid instead of methane. Unlike methane, which cattle discard as flatulence, acetic acid has benefits for cows as it aids muscle growth.

Rats trade initial rewards for long-term learning opportunities      (via sciencedaily.com) 

Scientists have provided evidence for the cognitive control of learning in rats, showing they can estimate the long-term value of learning and adapt their decision-making strategy to take advantage of learning opportunities.

Scientists find world's oldest European hedgehog      (via sciencedaily.com) 

The world's oldest scientifically-confirmed European hedgehog has been found in Denmark by a citizen science project involving hundreds of volunteers. The hedgehog lived for 16 years, 7 years longer than the previous record holder.

Creating 3D objects with sound      (via sciencedaily.com) 

Scientists have created a new technology to assemble matter in 3D. Their concept uses multiple acoustic holograms to generate pressure fields with which solid particles, gel beads and even biological cells can be printed. These results pave the way for novel 3D cell culture techniques with applications in biomedical engineering.

Cockatoos know to bring along multiple tools when they fish for cashews      (via sciencedaily.com) 

Goffin's cockatoos have been added to the short list of non-human animals that use and transport toolsets. Researchers show that the cockatoos carry multiple tools to their worksite when the job calls for it. This behavior has only been previously reported in chimpanzees, our closest relatives.

'It's me!' Fish recognizes itself in photographs, say scientists      (via sciencedaily.com)     Original source 

Scientists have demonstrated that fish think 'it's me' when they see themselves in a picture. The researchers found that the determining factor was not the fish seeing their own body but seeing their face.

HETDEX reveals galaxy gold mine in first large survey      (via sciencedaily.com) 

The Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) announced their first publicly released catalog of astronomical objects. Over 200,000 astronomical objects including distant stars and galaxies have been mapped in 3D for the first time. Astronomers will use the data to better determine the Hubble constant, used to gauge the expansion of the universe. Possible 'naked black hole' early highlight of science results from HETDEX survey. TACC systems Corral, Stampede2, and Maverick were used in the data analysis and storage. Data publicly available through JupyterHub notebooks.

Scientists develop new index based on functional morphology to understand how ancestors of modern birds used their wings      (via sciencedaily.com) 

Scientists have compared the relationship among the strength of flight bones, body mass, and the way modern birds fly to better understand the evolution of flight in birds and extinct animals, such as the Pteranodon.

Whiskers help nectar-eating 'acro bats' hover like hummingbirds      (via sciencedaily.com) 

A new study found that nectar-feeding bats evolved extra-long whiskers unlike those of any other bat species that allow them to hover as they feed on flowers, much like hummingbirds. The researchers used high-speed cameras to capture how the forward-facing whiskers provide enhanced spatial information for fast, precise flight maneuvers.

Footprints of galactic immigration uncovered in Andromeda galaxy      (via sciencedaily.com) 

Astronomers have uncovered striking new evidence for a mass migration of stars into the Andromeda Galaxy. Intricate patterns in the motions of stars reveal an immigration history very similar to that of the Milky Way.
