Scientists Develop Mathematical Index to Determine Healthy Gut Microbiome

What causes some people to develop chronic diseases such as rheumatoid arthritis, cancer and metabolic syndrome while others stay healthy? A major clue could be found in their gut microbiome, the trillions of microbes living inside the digestive system that regulate various bodily functions. To d


One of largest known T. rex skeletons up for auction at Christie’s

The British auction house Christie’s plans to sell the skeleton of one of the largest known Tyrannosaurus rexes in early October, the company said on Wednesday. The dinosaur known as “STAN,”, approximately 67 million years old, was discovered in 1987 in South Dakota by amateur p


NASA mulls possible mission to Venus after recent discovery of possible life

NASA is considering approving by next April up to two planetary science missions from four proposals under review, including one to Venus that scientists involved in the project said could help determine whether or not that planet harbors life. An international research team on Monday described e


Australia Scientists: Stinging Trees Contain 'Scorpion-like Venom'

Australia is notorious for its venomous spiders, snakes and sea creatures, but researchers have now identified "scorpion-like" toxins secreted by a tree that can cause excruciating pain for weeks. Split-second contact with the dendrocnide tree, a rainforest nettle known by its indigenous name gym


Satellites: Smoke from US Wildfires Reaches Europe

Satellite images show that smoke from wildfires in the western United States has reached as far as Europe, scientists said Wednesday. Data collected by the European Union's Copernicus Atmosphere Monitoring Service found smoke from the fires had traveled 8,000 kilometers through the atmosphere to


Girl power in the deep blue sea: World's largest fish are female

Male and female whale sharks - filter-feeding marine behemoths - grow at different rates, with females doing so more slowly but getting much larger than the guys, according to research that offers deeper insight into the biology of Earth’s largest fish. Researchers said on Wednesday they ha


Whales Stranded in Crocodile-Infested Australian River

Australia’s northern tropical rivers are renowned for being crocodile-infested, so the appearance of migrating humpback whales in one waterway has baffled marine scientists, who assume they simply took a wrong turn and got stuck. Marine ecologist Jason Fowler discovered three whales on a fi


Potential sign of alien life detected on inhospitable Venus

 Scientists said on Monday they have detected in the harshly acidic clouds of Venus a gas called phosphine that indicates microbes may inhabit Earth’s inhospitable neighbor, a tantalizing sign of potential life beyond Earth.   The researchers did not discover actual life forms, b


Dolly the Sheep scientists genetically engineer elite stud animals

Scientists have created gene-edited farm animals that could help improve food production and save endangered species. Pigs, goats and cattle have been engineered so that they become elite species which can produce sperm with traits such as disease resistance and higher meat quality. Researchers


Unique anatomy helps the African wild dog sustain its life on the run

The African wild dog distinguishes itself from rival predators like lions and hyenas by using the unique hunting style of chasing prey over long distances until the target collapses from exhaustion, instead of relying upon speed, strength or stealth. A comprehensive new anatomical study of this e


NASA sets out to buy moon resources mined by private companies

NASA on Thursday launched an effort to pay companies to mine resources on the moon, announcing it would buy from them rocks, dirt and other lunar materials as the U.S. space agency seeks to spur private extraction of coveted off-world resources for its use. NASA Administrator Jim Bridenstine wrot


Scientists confounded by new findings on universe's mysterious dark matter

 Dark matter, mysterious invisible stuff that makes up most of the mass of galaxies including our own Milky Way, is confounding scientists again, with new observations of distant galaxies conflicting with the current understanding of its nature.  Research published this week revealed an


Canadian Scientists Retrieve DNA of Extinct Animals from Soil

Researchers at McMaster University have developed a new technique to tease ancient DNA from soil, pulling the genomes of hundreds of animals and thousands of plants which many of them are long extinct. The DNA extraction method, outlined in the journal Quarternary Research, allows scientists to r


Dogs Really Love Owners, New Study Finds

Any dog owner will tell you that their pooch knows when it's time for a walk, a meal or snuggle. But new research commissioned by Canine Cottages, shows just how much dogs love their owners. During the study, special heart rate tracking collars were fitted to four different dogs and the change in


Scientific study: Hummingbirds reduce their body temperature during night hibernation

A team of researchers from the United States and South Africa discovered that several types of hummingbirds, which live in the Andes mountains, significantly reduce their body temperatures during their night hibernation. A team of researchers from the United States and South Africa discovered t


Marine Snails Have Unique Swimming Patterns, New Study

In the world's oceans, billions of tiny marine snails commute daily between surface waters, where they feed at night, to depths of several hundred meters during the day to rest. Marine snails play an important role in geochemical cycles and climate: 12-13% of the global carbonate flux occurs when


Gravitational waves could show what’s happening inside a star as it’s going supernova

It’s kind of hard to see inside a star as it’s blowing up, because of the whole “blowing up” part, but gravitational waves – tiny ripples in the fabric of spacetime itself – may help astronomers unlock how the biggest stars die. It takes a lot of raw energy to


Brain switch lets us control a kind of suspended animation in mice

Two groups of researchers have independently discovered a “brain switch” that makes starving mice enter a hibernation-like state to save energy. They hope it may be possible to induce similar states in people. “Suspended animation could transform medicine and open the door to fa
