Feathered dinosaurs were even fluffier than we thought

Tue, 11/28/2017 - 21:04

Scientists have revealed new details about dinosaur feathers and enabled scientists to further refine what is potentially the most accurate depiction of any dinosaur species to date.

Trophy hunting may cause extinction in a changing environment

Tue, 11/28/2017 - 21:04

Trophy hunting and other activities involving the targeting of high-quality male animals could lead to the extinction of certain species faced with changing environmental conditions, according to new research.

Abominable Snowman? Nope: Study ties DNA samples from purported Yetis to Asian bears

Tue, 11/28/2017 - 21:04

The Yeti or Abominable Snowman -- a mysterious, ape-like creature said to inhabit the high mountains of Asia -- looms large in the mythology of Nepal and Tibet. Now, a new DNA study of purported Yeti samples from museums and private collections is providing insight into the origins of this Himalayan legend.

Dogs get the Hollywood treatment to make animal animations more realistic

Tue, 11/28/2017 - 17:00

Researchers are creating a library of movement data from different dog breeds, to make animal animations in films and video games more realistic.

There's a deeper fish in the sea

Tue, 11/28/2017 - 17:00

The ocean's deepest fish doesn't look like it could survive in harsh conditions thousands of feet below the surface. Instead of giant teeth and a menacing frame, the fishes that roam in the deepest parts of the ocean are small, translucent, bereft of scales -- and highly adept at living where few other organisms can. A new fish species, the deepest in the ocean, was just discovered.

Dogs mouth-lick to communicate with angry humans

Tue, 11/28/2017 - 10:02

New research has found that dogs lick their mouths as a response to looking at angry human faces, suggesting that domestic canines may have a functional understanding of emotional information.

A horse is a horse, of course, of course -- except when it isn't

Tue, 11/28/2017 - 07:09

Scientists have discovered a previously unrecognized genus of extinct horses that roamed North America during the last ice age. The new findings are based on an analysis of ancient DNA from fossils of the enigmatic 'New World stilt-legged horse' excavated from sites such as Natural Trap Cave in Wyoming, Gypsum Cave in Nevada, and the Klondike goldfields of Canada's Yukon Territory.

Sharks evolved aircraft-like attributes to suit habitats

Mon, 11/27/2017 - 13:20

Researchers report that shark species have evolved diverse physical attributes to help them thrive in different ocean ecosystems.

As climate warms, mice morph

Mon, 11/27/2017 - 11:58

Milder winters have led to physical alterations in two species of mice in southern Quebec in the past 50 years -- providing a textbook example of the consequences of climate change for small mammals. These findings also reveal a stark reversal in the proportions of the two mice populations present in the area, adding to evidence that warming temperatures are driving wildlife north.

Muscles can't get any faster than this ... a fundamental muscle speed limit

Mon, 11/27/2017 - 10:47

When birds sing their elaborate songs, bats echolocate, rattlesnakes rattle and toadfish hum they use so-called superfast muscles, the fastest vertebrate muscles known. New research shows that these muscles have reached a maximum speed attainable in any vertebrate muscle.

New technique can detect impurities in ground beef within minutes

Mon, 11/27/2017 - 08:59

Researchers have found a better way to identify unwanted animal products in ground beef. They used a laser-equipped spectrometer and statistical analysis to determine with 99 per cent accuracy whether ground beef samples included other animal parts. They were able to say with 80 per cent accuracy which animal parts were used, and in what concentration.

New butterfly species discovered in Russia with an unusual set of 46 chromosomes

Mon, 11/27/2017 - 08:59

Finding a new species is a rare event in easy-to-see and well-studied organisms like butterflies, especially if they inhabit well-explored areas such as Europe. Researchers have now discovered the previously unknown South-Russian blue using an array of modern research techniques. Furthermore, the new species was found to possess 46 chromosomes, just like a human, whereas its closest relative has 68 chromosomes.

Family-friendly overpasses are needed to help grizzly bears, study suggests

Mon, 11/27/2017 - 07:49

Researchers have determined how female grizzly bears keep their cubs safe while crossing the Trans-Canada Highway.

150 years of snake collections: Data bank proves rich snake diversity in the neotropics

Fri, 11/24/2017 - 06:47

An extensive database constructed for snakes of the American tropics has now been released by researchers. This database is made up of museum collections from the past 150 years and demonstrates that some Neotropical regions, such as the Cerrado in the central Brazil, contain a disproportionately high diversity. Furthermore, some other diverse regions are disproportionally under sampled, such as the Amazon.

Small but distinct differences among species mark evolution of human brain

Fri, 11/24/2017 - 06:43

The most dramatic divergence between humans and other primates can be found in the brain, the primary organ that gives our species its identity. However, all regions of the human brain have molecular signatures very similar to those of our primate relatives, yet some regions contain distinctly human patterns of gene activity that mark the brain's evolution and may contribute to our cognitive abilities, a new study has found.

New species can develop in as little as two generations, Galapagos study finds

Fri, 11/24/2017 - 06:43

A study of Darwin's finches, which live on the Galapagos Islands in the Pacific Ocean, has revealed direct genetic evidence that new species can arise in just two generations.

Radiographs of Dolly's skeleton show no signs of abnormal osteoarthritis

Thu, 11/23/2017 - 07:51

Original concerns that cloning caused early-onset osteoarthritis (OA) in Dolly the sheep are unfounded, report experts.

EU trade ban brings down global trade in wild birds by 90 percent

Wed, 11/22/2017 - 13:10

Trade of wild birds has dropped 90 percent globally since EU banned bird imports in 2005. A new study demonstrates how it decreased the number of birds traded annually from 1.3 million to 130,000. International trade of wild birds is a root cause of exotic birds spreading worldwide.

Bowhead whales come to Cumberland Sound in Nunavut to exfoliate

Wed, 11/22/2017 - 13:10

Aerial drone footage of bowhead whales in Canada's Arctic has revealed that the large mammals molt and use rocks to rub off dead skin.

Ribbed mussels could help improve urban water quality

Wed, 11/22/2017 - 11:32

Ribbed mussels can remove nitrogen and other excess nutrients from an urban estuary and could help improve water quality in other urban and coastal locations, according to a study in New York City's Bronx River. The findings are part of long-term efforts to improve water quality in the Bronx River Estuary.
