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 ...

Is it too late to halt climate change? No, no, and no.

Disheartened, many are convinced there's no fighting climate change at this point. There's no single on/off switch, however, so we can still lessen its effects. It's up to us to make the crisis our leaders' priority. With unprecedented extreme weather buffeting basically everyone everywhere, with places like idyllic Kirbati disappearing beneath the rising seas, and with Australia on fire for goodness sake, it's easy to get the feeling that humanity has already failed to meet the greatest chal...

‘PigeonBot’ brings flying robots closer to real birds

Try as they might, even the most advanced roboticists on Earth struggle to recreate the effortless elegance and efficiency with which birds fly through the air. The “PigeonBot” from Stanford researchers takes a step toward changing that by investigating and demonstrating the unique qualities of feathered flight. On a superficial level, PigeonBot looks a bit, shall we say, like a school project. But a lot of thought went into this rather haphazard-looking contraption. Turns out the way birds fly ...

Scientists Have Been Talking About Climate Change for More Than a Century. Here’s Why It Took So Long for the World to Listen

This post is in partnership with the History News Network, the website that puts the news into historical perspective. A version of the article below was originally published at HNN. The girl got up to speak before a crowd of global leaders. “Coming here today, I have no hidden agenda. I am fighting for my future. Losing my future is not like losing an election or a few points on the stock market. I am here to speak for all generations to come.” She continued: “I have...

Stanford researchers manage to put a particle accelerator on a silicon chip

In scientific pursuits, like the search for dark matter, researchers sometimes use high-power particle accelerators. But these giant machines are extremely expensive and only a handful of them exist, so teams must travel to places like the SLAC National Accelerator Laboratory in Menlo Park, California, where Stanford University operates at two-mile-long particle accelerator. This may change, though. Researchers believe they have developed an alternative: a laser-driven particle accelerator that ...

This particle accelerator fits on the head of a pin

If you know nothing else about particle accelerators, you probably know that they’re big — sometimes miles long. But a new approach from Stanford researchers has led to an accelerator shorter from end to end than a human hair is wide. The general idea behind particle accelerators is that they’re a long line of radiation emitters that smack the target particle with radiation at the exact right time to propel it forward a little faster than before. The problem is that depending on the radiation yo...

How to recognize an alien when you see one

What would convince you that aliens existed? The question came up recently at a conference on astrobiology, held at Stanford University in California. Several ideas were tossed around – unusual gases in a planet’s atmosphere, strange heat gradients on its surface. But none felt persuasive. Finally, one scientist offered the solution: a photograph. There was some laughter and a murmur of approval from the audience of researchers: yes, a photo of an alien would be convincing evidence, the holy gra...

Super-soldier T-cells fight cancer better after a transformational DNA delivery

I enjoy online shopping. However, I often find myself fussing about the delivery options during checkout. This is because not all delivery services are equally efficient and stress-free. This personal experience has also inspired my research. As a postdoctoral scholar at Stanford University, I have engineered tiny nano-materials – objects about 10,000 times smaller than a grain of rice – to better deliver DNA into white blood cells called T-cells that defend us against cancer. My method – which ...

In a first for cell biology, scientists observe ribosome assembly in real time

A team of scientists from Scripps Research and Stanford University has recorded in real time a key step in the assembly of ribosomes -- the complex and evolutionarily ancient 'molecular machines' that make proteins in cells and are essential for all life forms. They reveal in unprecedented detail how strands of RNA are 'chaperoned' by ribosomal proteins into folding properly; the findings overturn the longstanding belief that ribosomes are assembled in a tightly controlled, step-wise process.

Study suggests AI’s disruptive effect on jobs will hit higher on economic and education scales

When experts talk about the disruptive effects of artificial intelligence, they tend to focus on low-paid laborers — but a newly published study suggests higher-paid, more highly educated workers will be increasingly exposed to job challenges. The study puts Seattle toward the top of the list for AI-related job disruption. The analysis, which draws on work by researchers at Stanford University and the Brookings Institution, makes use of a novel technique that connects AI-related patents with the...

Scientists find promising drug combination against lethal childhood brain cancers

Researchers have devised a new, promising plan of attack against deadly childhood brain cancers called diffuse midline gliomas (DMG). NCATS and Stanford University scientists and their colleagues showed that combining two drugs killed DMG patient cells grown in the laboratory and in animal models. The drugs countered the effects of a genetic mutation that causes the diseases. Their studies also uncovered an unrecognized vulnerability in the cancer cells that scientists may be able to exploit.

Want to run more efficiently? Tie your feet together, say scientists

It used to be that tying someone’s shoes together was a nasty prank, but now it’s a performance-enhancing feat of bio-mechanical engineering. A team of researchers and engineers at Stanford University have developed a radical new method to increase the running efficiency of humans: they put a rubber band between a pair of shoes. This might not sound like a feat of modern technology, but the science behind it is actually quite interesting. According to the team’s research paper, we’re poorly engi...

Stanford’s Doggo is a petite robotic quadruped you can (maybe) build yourself

Got a few thousand bucks and a good deal of engineering expertise? You’re in luck: Stanford students have created a quadrupedal robot platform called Doggo that you can build with off-the-shelf parts and a considerable amount of elbow grease. That’s better than the alternatives, which generally require a hundred grand and a government-sponsored lab. Due to be presented (paper on arXiv here) at the IEEE International Conference on Robots and Automation, Doggo is the result of research by the Stan...

Scientists developing blood test for chronic fatigue syndrome

US scientists at Stanford University are developing a blood test using a biomarker that allows doctors to diagnose chronic fatigue syndrome. Chronic fatigue syndrome (CFS) is expressed through a feeling of profound fatigue, but also with headaches, difficulties concentrating or sleeping, and joint pain. "When individuals with chronic fatigue syndrome seek help from a doctor, they may undergo a series of tests that check liver, kidney and heart function, as well as blood and immune cell counts.

Libor's Looming Demise Is a Mammoth Financial Engineering Task

Darrell Duffie, a finance professor at Stanford University, has also underscored the risks involved with shifting away from a set of benchmarks that underpin some $200 trillion in dollar-denominated instruments. “This is the largest financial engineering project the world has ever seen,” Duffie said on a conference call hosted by financial-technology firm GLMX on Thursday. The ARRC is backing SOFR, but the new benchmark developed by the New York Fed and the U.S. Treasury still has yet to fully...

This self-driving AI faced off against an champion racer (kind of)

Developments in the self-driving car world can sometimes be a bit dry: a million miles without an accident, a 10 percent increase in pedestrian detection range, and so on. But this research has both an interesting idea behind it and a surprisingly hands-on method of testing: pitting the vehicle against a real racing driver on a course. To set expectations here, this isn’t some stunt, it’s actually warranted given the nature of the research, and it’s not like they were trading positions, jockeyin...

Stanford scientists convert seawater to hydrogen fuel

Using solar power, electrodes, and saltwater from the San Francisco Bay, a team of research scientists at Stanford University managed to generate hydrogen fuel, a fuel option that doesn't emit carbon dioxide. This approach creates hydrogen fuel from the San Francisco Bay's saltwater, whereas traditional methods rely on impractical amounts of purified water to have significant real-life application.

You Might Be a Robot. This Is Not a Joke.

As some see it, the rise of artificial intelligence will make humans obsolete — or at least force people to think more like machines. As the Stanford University legal scholars Bryan Casey and Mark Lemley put it provocatively in the title of a new paper forthcoming in the Cornell Law Review, “You Might Be a Robot.” They don’t mean that literally, but they’re completely serious.

More than just memories: a new role for the hippocampus during learning

Without an intact hippocampus, forming new memories is impossible. Researchers from Arizona State University and Stanford University found an equally important role for the hippocampus: feeding information to brain areas responsible for learning. Using fMRI, the research team found it was the hippocampus that encoded associations between relevant features of the environment during learning and that the associations encoded in the hippocampus were used by brain systems responsible for learning.
