Arctic fox amazes scientists with 2,000 mile trek in 76 days – CNN

The fox was fitted with a transmitter so researchers could track its movements.
It covered an average of 46.3 km (28.8 miles) per day, and amazingly traveled 155 km (96.3 miles) in just one day as it crossed the Greenland ice sheet.
This is the fastest rate recorded for this species, 1.4 times faster than the previous known record held by an adult male Arctic fox that was tracked in Alaska.
The Arctic fox broke the record for the longest distance covered by the species in one day.
Scientists believe the fox may have sped up as it crossed the ice sheet due to limited foraging opportunities.
However it slowed down significantly on two occasions, covering less than 10 km (6.2 miles) per day for 48 hours.
This may be due to physical barriers on the sea ice, bad weather, or good feeding opportunities.
Experts have previously speculated that the Arctic fox may eat crustaceans from open water.
The fox left Spitsbergen on 26 March 2018 and arrived in Canada just over two months later.
Its current whereabouts is unknown as the transmitter stopped working on 6 February 2019.
The Arctic is undergoing important changes as warming temperatures affect the ice.
It is heating up twice as fast as the global average, causing massive melting of sea ice and opening up the area to exploration.
Russia is set to tow a floating nuclear power plant to the Arctic port town of Pevek next month as part of plans to expand its interests in the region.
These plans have sparked concerns in the US, which also sees economic opportunities as Arctic sea ice melts.

Scientists may have found a better way to spot early signs of dementia: our eyes

Bild
As our body’s central control center, the brain has to keep going at all costs. It makes sense that it’s surrounded by biological safeguards: a bony skull, a sack of tissue, and blood vessels that filter out most infectious bugs. When neurons start to decline—as some do naturally with age—the brain can even quickly rewire networks before we notice anything is amiss. But these same safeguards are a huge obstacle for scientists trying to study the brain’s decline—specifically dementia. Grey matter is excellent at adapting to the slow buildup of abnormal proteins, the cause of several forms of dementia , and it lacks the same pain receptors as the rest of our body. So by the time a patient starts becoming forgetful, or having trouble concentrating, the cellular damage is already substantial—and usually irreversible. In order to slow or prevent dementia, scientists will have to be able to spot it before cognitive systems collapse. Current diagnostic tools for Alzheimer’s, the most com...

Here’s a better way to convert dog years to human years, scientists say | Science | AAAS

A biological clock governs aging in dogs just as in humans. Here’s a better way to convert dog years to human years, scientists say By Virginia Morell Nov. 15, 2019 , 3:42 PM Our Scotch collie, Buckaroo, is just shy of 14 years old. Following the long-debunked but still popular idea that one dog year equals seven human years, he’s almost a centenarian. (This “formula” may be based on average life spans of 10 and 70 years for dogs and people, respectively.) Now, researchers say they have a new formula (see calculator below)  to convert dog years to human years—one with some actual science behind it. The work is based on a relatively new concept in aging research: that chemical modifications to a person’s DNA over a lifetime create what is known as an epigenetic clock. Scientists have built a case that one such modification, the addition of methyl groups to specific DNA sequences, tracks human biological age—that is, the toll that disease, poor lifestyle, and genetics take on our...

Granny killer whales pass along wisdom—and extra fish—to their grandchildren | Science | AAAS

A young killer whale swims between two older ones. Granny killer whales pass along wisdom—and extra fish—to their grandchildren By Eva Frederick Dec. 9, 2019 , 4:30 PM Many human grandmothers love to spoil their grandchildren with attention and treats, and for good reason: Studies have shown that having a living grandmother increases a child’s chance of survival. Now, new research shows the same may be true for killer whales. By providing young animals with some freshly caught salmon now and then—or perhaps with knowledge on where to find it—grannies increase their grand-offspring’s chance of survival. The new study is the first direct evidence in nonhuman animals of the “grandmother hypothesis.” The idea posits that females of some species live long after they stop reproducing to provide extra care for their grandchildren . “It’s very cool that these long-lived cetaceans have what looks like a postfertile life stage,” says Kristen Hawkes, an anthropologist at the University of Ut...
