Algorithms 'consistently' more accurate than people in predicting recidivism, study says

In a study with potentially far-reaching implications for criminal justice in the United States, a team of California researchers has found that algorithms are significantly more accurate than humans in predicting which defendants will later be arrested for a new crime. The researchers -- from Stanford University and the University of California, Berkeley -- found that risk assessment tools approached 90% accuracy in predicting which defendants might be arrested again, compared to about 60% for ...

California unveils early warning earthquake app

The app, created by the University of California, Berkeley, and unveiled on the 30th anniversary of the deadly Loma Prieta quake, uses ground motion sensors located across the state to detect the start of earthquakes before humans can feel them. "Nothing can replace families having a plan for earthquakes and other emergencies," Governor Gavin Newsom said in unveiling the warning system.

Watching Nature Documentaries Can Produce “Real Happiness,” Finds a Study from the BBC and UC-Berkeley

Hollywood science fiction films imagine future humans in worlds that are no longer green, or never were—from Soylent Green’s dying Earth to that of Interstellar. And from Soylent Green to Ad Astra, humans in the future experience plant and animal life as simulations on a screen, in hyperreal photography and video meant to pacify and comfort. Maybe we live in that world already, to some extent, with apocalyptic films and science fiction expressing a collective mourning for the extinctions...

Scientists uncover 1,000-year-old shamanic pouch containing ancient hallucinogens

The remains of a fox-snout pouch believed to have been owned by a South American shaman a thousand years ago has revealed traces of powerful hallucinogenic drugs.The ancient find indicates people were not only using single plants known to produce hallucinations, but were blending various plants to create potent compounds which could result in lengthier and more powerful trips.Anthropologists made the rare find in the now-dry Sora River valley in southwestern Bolivia in 2010. The area has evidenc...

Offerings to Supernatural Deities Discovered in Lake Titicaca in the Andes

A team of archaeological divers has uncovered dazzling treasures at the bottom of Lake Titicaca, including a puma carved out of the blue gemstone lapis-lazuli, gold medallions and a turquoise stone pendant.These riches were likely offered to supernatural deities hundreds of years ago by elite people from the Tiwanaku culture, which established the first large state in the Andes Mountains from about 500 to 1100, the researchers said.But these swanky goods weren't the only lavish aspect of the...

Physicists May Have Found a Way to 'Untangle' Information Trapped in a Black Hole

Black holes are gravitational monsters, squeezing gas and dust down to a microscopic point like great cosmic trash compactors. Modern physics dictates that, after being consumed, information about this matter should be forever lost to the universe. But a new experiment suggests that there might be a way to use quantum mechanics to gain some insight into the interior of a black hole."In quantum physics, information cannot possibly be lost," Kevin Landsman, a physics graduate student at the Joint ...

How a Distant Alien World Was Saved from an Interstellar Exile

A distant alien world that was potentially on its way into exile in interstellar space was rescued by the gravitational pull of a passing pair of stars, a new study argues.These findings support arguments that close stellar misses help sculpt planetary systems, the researchers said.Although Earth and most of its sibling planets have relatively circular orbits around the sun's equator, Pluto and many other dwarf planets have more elongated, tilted orbits. Previous research suggested these dis...

Solar Wind Leaves 'Sunburn' Scars on Lunar Surface, NASA Missions Reveals

People on Earth who've gotten sunburns are familiar with the sun's powerful rays -- but the moon suffers from sunburn, too. Some regions of the lunar surface exhibit a distinctive pattern of darker and lighter swirls. Using NASA's ARTEMIS mission -- which stands for Acceleration, Reconnection, Turbulence and Electrodynamics of the Moon's Interaction with the Sun -- astronomers have revealed new clues about the origin of these swirls. The sun releases a constant flow of charged pa...

As the climate warms, there may be a slight increase in male newborns

Scientists have long theorized that temperature has some effect on the sex ratios of populations.Recent research shows links between rising temperatures and increases in the ratio of male newborns.Nobody can say exactly whether temperature causes changes in sex ratio, however it's likely that climate change will force humans to adapt in ways we can't yet anticipate. None The United Nations' top climate science panel warned, in October, of the disastrous consequences around the world if temperat...

If Aliens Are Causing Weird Dimming of 'Tabby' Star,' They Aren't Using Lasers to Do It

The evidence for aliens around one of the weirdest stars in our galaxy -- Boyajian's star -- is not looking promising. The star's unusual dimming events have garnered some bizarre theories: One of them speculates that an alien megastructure is responsible for the light anomalies. But, a new study searching for signs of extraterrestrials has not turned up any evidence to back up that theory. Such an alien civilization, capable of building a starlight-blocking megastructure, would possib...

Is habitat restoration actually killing plants in the California wildlands?

New work by a University of California, Berkeley team shows for the first time just how widespread and deadly the threat of pathogens from restoration nurseries may be to natural forests. The team surveyed five native plant nurseries in Northern California and found that four harbored exotic, or non-native, Phytophthora pathogens. New management techniques, coupled with new methods for detecting pathogens, can help these nurseries limit the spread of exotic pathogens into the wild.

The Bacteria in Your Gut Produce Electricity

Some types of bacteria that are either commonly consumed or already found in our guts can create electricity, according to a new study published Wednesday (Sept. 12) in the Journal Nature. Electricity-generating, or "electrogenic," bacteria aren't something new — they can be found in places far away from us, like at the bottom of lakes, said senior author Daniel Portnoy, a microbiologist at the University of California, Berkeley. But until now, scientists had no idea that bacteria found in dec...

We Pay Attention Four Times Per Second

Two new studies in the scientific publication Neuron—authored by research teams from Princeton University and the University of California-Berkeley—posit that attention does not hone in like a spotlight, rather, it strobes in and out four times per second. “Perception is discontinuous,” says Sabine Kastner of Princeton Neuroscience Institute, but it is not flickering on and off entirely. Rather, we cycle between “periods of maximum focus and periods of …
