As a devout Epicurean, I wish they posted the actual text.


The text is thought to be a previously unknown work on pleasure by Philodemus, an Epicurean philosopher who lived in Herculaneum.
 
A moon of Saturn that resembles the Death Star from Star Wars because of a massive impact crater on its surface has a hidden ocean buried miles beneath its battered crust, researchers say.

The unexpected discovery means Mimas, an ice ball 250 miles wide, becomes the latest member of an exclusive club, joining Saturn’s Titan and Enceladus and Jupiter’s Europa and Ganymede as moons known to harbour subterranean oceans.

“It’s quite a surprise,” said Valéry Lainey, an astronomer at the Observatoire de Paris in France. “If you look at the surface of Mimas, there’s nothing that betrays a subsurface ocean. It’s the most unlikely candidate by far.”


Peculiarities in Mimas’s orbit had led astronomers to entertain two possibilities: either it contained an elongated core shrouded in ice, or an internal ocean that allowed its outer shell to shift independently of the core.

By analysing thousands of images from Nasa’s Cassini mission to Saturn, Lainey and his colleagues reconstructed the precise spin and orbital motion of Mimas as it looped around the gas giant. Their calculations showed Mimas must possess a hidden subsurface ocean to move the way it does.

“There is no way to explain both the spin of Mimas and the orbit with a rigid interior,” Lainey said. “You definitely need to have global ocean on which the icy shelf can slip.”

Their calculations suggest an ocean 45 miles deep lurks beneath Mimas’s 15-mile-thick icy shell, with temperatures near the sea floor reaching tens of degrees celsius. The ocean would account for more than half of Mimas’s volume. Details are published in Nature.……

 
After a decades-long and largely fruitless hunt for drugs to combat Alzheimer’s disease, an unlikely candidate has raised its head: the erectile dysfunction pill Viagra.

Researchers found that men who were prescribed Viagra and similar medications were 18% less likely to develop the most common form of dementia years later than those who went without the drugs.

The effect was strongest in men with the most prescriptions, with scientists finding a 44% lower risk of Alzheimer’s in those who received 21 to 50 prescriptions of the erectile dysfunction pills over the course of their study.


While the findings are striking, the observational study cannot determine whether Viagra and similar pills protect against Alzheimer’s or whether men who are already less prone to the condition are simply more likely to use the tablets.

“We can’t say that the drugs are responsible, but this does give us food for thought on how we move into the future,” said the lead author Dr Ruth Brauer at University College London. “We now need a proper clinical trial to look at the effects of these drugs on Alzheimer’s in women as well as men.”………

So if they start prescribing this as an Alzheimer medication, will "Prolonged Erections" be listed as a side effect?
 
It would be amazing if one of the worst disasters in human history led to a cure for cancer


Mutant wolves that roam the human-free Chernobyl Exclusion Zone have developed cancer-resilient genomes that could be key to helping humans fight the deadly disease, according to a study.

As someone who finds Chernobyl absolutely fascinating, this is some spectacular news.
 
Whether it is a simple handshake or a full-body hug, the warmth of another person adds a human touch to social interactions. Now researchers have created a device that allows people with amputations to experience such natural temperature sensations using their prostheses.

The team say the innovation is a first and paves the way for integrating a host of sensations into artificial limbs.

Prof Solaiman Shokur, a senior author of the research at the Swiss Federal Institute of Technology Lausanne, said it was known that boosting sensory feedback from a prosthesis could help people feel an artificial limb was part of their body.

“To give a natural sensation, you cannot do it without temperature,” he said.

Shokur added that the approach could also enable people with artificial limbs to perceive whether an object was dangerously hot and help them distinguish between different materials.

“Beyond that it opens a window to the more social aspect of touch,” he said.……

 
A stone age wall discovered beneath the waves off Germany’s Baltic coast may be the oldest known megastructure built by humans in Europe, researchers say.

The wall, which stretches for nearly a kilometre along the seafloor in the Bay of Mecklenburg, was spotted by accident when scientists operated a multibeam sonar system from a research vessel on a student trip about 10km (six miles) offshore.

Closer inspection of the structure, named the Blinkerwall, revealed about 1,400 smaller stones that appear to have been positioned to connect nearly 300 larger boulders, many of which were too heavy for groups of humans to have moved.


The submerged wall, described as a “thrilling discovery”, is covered by 21 metres of water, but researchers believe it was constructed by hunter-gatherers on land next to a lake or marsh more than 10,000 years ago.

While the purpose of the wall is hard to prove, scientists suspect it served as a driving lane for hunters in pursuit of herds of reindeer.…..

 

Artificial intelligence helps predict whether antidepressants will work in patients​


This could help my family out so much. We often struggle to find the right meds to help medicate my two sons with their autism. It’s heart breaking watching them struggle through it. This could possibly help them and others like them so much. Fingers crossed
