Just goes to show you how utterly insignificant we are as a species.  We could wipe ourselves out and from a historical standpoint, we'd barely register as a blip on the cosmological radar.  The good news is the planet would heal quickly and move on quite nicely without us.

So...

Go Earth!

Physicists smoke a ton of weed, attempt to prove the universe is a computer simulation

QuoteTechnology Review explains that "the problem with all simulations is that the laws of physics, which appear continuous, have to be superimposed onto a discrete three dimensional lattice which advances in steps of time."

What that basically means is that by just being a simulation, the computer would put limits on, for instance, the energy that particles can have within the program.

These limits would be experienced by those living within the sim - and as it turns out, something which looks just like these limits do in fact exist.

For instance, something known as the Greisen-Zatsepin-Kuzmin, or GZK cut off, is an apparent boundary of the energy that cosmic ray particles can have. This is caused by interaction with cosmic background radiation. But Beane and co's paper argues that the pattern of this rule mirrors what you might expect from a computer simulation.

Naturally, at this point the science becomes pretty tricky to wade through - and we would advise you read the paper itself to try and get the full detail of the idea.

Electric underwear? They're for bedsores

For those immobilized in a hospital bed, pressure sores can bring pain, slow recovery and require medical attention.
"Pressure ulcers can be terribly debilitating," Robyn Rogers, a research nurse at the University of Calgary, told BBC News. "Their incidence has not changed since the 1940s, indicating that the current methods of prevention simply are not working."
Hence a new, well-named idea: The Smart-e-Pants system.
Researchers at the university developed and tested boxer shorts with two pads of electrodes, one for each butt cheek. Twenty-three patients wore them, got 10 seconds of electrical stimulation at 10-minute intervals, 12 hours a day during the four-week test.
The mild current mimicked fidgeting, preventing the development of pressure sores, which arise when people are stuck in one position for too long, compressing the skin and cutting off the blood supply. Elderly patients are particularly susceptible because of their poor circulation.
The findings were reported at the annual meeting of the Society for Neuroscience in New Orleans on Monday.
Sean Dukelow, who led the study, said the pants worked so well in the small trial that none of the patients involved got pressure ulcers for the month of the experiment. "Most of them wanted to keep the device after they were done," he told The Guardian.

At least until it either flops or gets bought out by an oil company and we never hear another word about it.

Some of you are going to get to talk to cops more often.

QuoteNidhi Subbaraman of MIT Review reports that scientists are working on infrared facial recognition algorithms that will map the heat along the surface of the face.
Drunks, it turns out, have certain patterns of heat along their faces. As Liat Clarke of Wired put it, the scientists found that "when inebriated, an individual's nose tends to become warmer while their forehead remains far cooler."

MIT's artificial leaf is ten times more efficient than the real thing

QuoteWith a single gallon of water, Nocera says, the chip could produce enough electricity to power a house in a developing country for an entire day. Provide every house on the planet with an artificial leaf and we could satisfy our 14 terrawatt need with just one gallon of water a day.

Only because the house in a developing country doesn't have anything that requires electricity.
