Turns out Summers’s attitude may be to blame, according to a new study from vocational psychologists at the University of Wisconsin-Madison. The three-year report sought to identify what encourages girls to pursue math and science, and what barriers keep them from the subjects. In the 20 years prior to the study, experts believed that girls lacked interest and tried to combat their indifference. The report revealed that a missing factor – confidence – often precedes interest....
The fire began on October 9 near Vancouver, Washington Nakia Creek Fire, ignited near Vancouver, Washington, (about 10 miles outside of Portland, Oregon) and it broke containment lines on Sunday October 16. It’s estimated that it grew from 156 acres to 2,000 acres in only a matter of hours due in large part to a combination of extremely warm temperatures, low humidity, and high wind speeds. Temperatures reached a steamy 86 degrees on Sunday, compared to the average temperatures in the low 60s this time of year....
There’s a lot on the Martian surface that is of interest to scientists, but little is known about what is happening on the inside. We don’t exactly know what the planet’s core is made of, how big it is, or how geologically active Mars might be. In order to understand these mysteries, we have to look below the surface. That’s InSight’s speciality. But first the lander has to survive the “seven minutes of terror” during atmospheric entry, descent, and landing (otherwise known as EDL)....
Now that the James Webb Space Telescope has finally launched and is in full science operation mode, the astronomical community is looking with eager anticipation to the next major launch, the Nancy Grace Roman Space Telescope. Among other directives, the Roman will be an exoplanet hunter extraordinaire, revealing key information about the formation of solar systems and planets like our own. But, initially, it looked like the mission would never happen....
The scientists behind the mission think of themselves as cosmic paleontologists, naming the mission after the renowned “Lucy” skeleton, which revealed a new chapter of human evolutionary history. The Lucy spacecraft will chase down a handful of Trojan asteroids, fossil-like fragments left over from Jupiter’s formation that the gas giant has harbored in two gravitationally protected zones for the last 4.6 billion years. From Earth, the Trojans show up only as specks of light....
But these benefits can be somewhat abstract, even if we know they exist, and that can make it challenging to argue for investing in nature itself. That’s why researchers at Griffith University in Australia wanted to quantify just how much nature helps our mental health. In a recent study, they estimated that visits to national parks generate global mental health improvements to the tune of trillions of dollars by alleviating what would be huge costs in healthcare and work productivity....
As researchers across the world call for a careful investigation into the origins of the pandemic, the findings add more clarity into how SARS-CoV-2 might have jumped from a wild population of animals into humans. “This report clearly places [SARS-CoV-2] susceptible animals smack in the middle of Wuhan,” says Robert Garry, a virologist at Tulane University who has written about the origins of the COVID-19, but was not involved in the research....
Now scientists at Harvard University have developed a prototype device that moves portable terahertz scanners a little closer to reality. Previously, the radiation sources were just too big and complex. The Harvard group used commercially-available nano-technology to develop a device that works at room temperature, and doesn’t have to be cryogenically-cooled, like previous versions. “Terahertz imaging and sensing is a very promising but relatively new technology that requires compact, portable and tunable sources to achieve widespread penetration,” says one of the lead scientists, Federico Capasso....
The slow loris may have gained popular fame through YouTube videos in which terrified lorises grasp umbrellas, but it’s actually a fascinating animal even when it’s not fearing for its life. (Yep, that’s what’s going on in those videos: when threatened, lorises become docile and passive, which is different from being friendly. Oh, and the pet trade in lorises is brutal and horrifying, just FYI.) It’s one of very few venomous mammals and even fewer venomous primates; it has a poison gland on its elbow which it licks to mix with its saliva, giving it a venomous bite....
The story goes like this. Nicolas Cage was, until recently, the owner of a Tyrannosaurus bataar skull, which he paid $276,000 for in an anonymous auction eight years ago. But a recent investigation found that that skull and several other fossils had been stolen from Mongolia’s Gobi desert. Cage immediately agreed to turn over the skull to the federal government upon learning that it was stolen. Mongolia has been struggling to get back numerous rare dinosaur fossils for years now....
Musk more than halved the company’s global workforce from 7,500 to just over 2,000 since assuming leadership, a reduction many experts and former employees warn opens up one of the world’s most popular social media platforms to numerous content, engineering, and security issues. As one ex-staffer told WaPo, among the many staff cuts and department shutterings included the resignation of “all the China influence operations and analysts,” leaving a massive blindspot across the country....
“The main way that [the new guidelines] will prevent more cancers is by facilitating screening,” says Debbie Saslow, the managing director of HPV and gynecological cancers at the American Cancer Society and one of the authors of the new report. “And by that, I mean it’s a very simplified guideline: Start at 25, get the HPV test every five years until age 65, and then stop.” HPV is the most common sexually transmitted infection in the United States....
It’s well-known that natural disasters can have devastating effects on the health of communities: They can spread disease, damage hospitals, and make accessing nutritious food and clean water difficult. However, most of what researchers know about those effects is generalized. Nogueira wanted to see how these catastrophes affect specific groups—and found, in a study published this week, that patients in treatment for non-small cell lung cancer during hurricane disasters have worse survival rates than those unaffected by hurricanes....
That seems to be for good reason. Somewhere between 500 billion and a trillion plastic bags are consumed each year across the globe—that’s 1 to 2 million a minute—and a lot of those end up polluting the environment, harming even the tiniest organisms. But an environmentally-conscious shopper might feel overwhelmed when they try to weigh the pros and cons of alternatives like polypropylene, polyester, and cotton totes. As a recent Quartz article pointed out, these options aren’t necessarily better for the environment, at least according to life cycle assessments that consider the energy and resources used to manufacture, transport, and dispose of them....

Paleontologists from the National Museum of Natural Sciences in Madrid, the Natural History Museum in London, and elsewhere recently led a dig in the Gorham and Vanguard caves on eastern Gibraltar beach, where they found some very stale left-overs. They discovered bones from monk seals and bottlenose dolphins, illegal to serve now, but apparently an epicurean treat for the Neanderthals. Most of the bones were from young mammals, suggesting that the seafood hunt occurred during breeding season, when the animals came to shore....
This polyhedron is a classic prism made from professional-grade optical crystal glass. If you’ve never used a prism before, you’ll enjoy splitting the different wavelengths that make up light into red, orange, yellow, green, blue, indigo, and violet. Hold the prism in different positions in front of your lens to get hazy, ghostly, or double exposure effects, and of course, add rainbows to your subjects. This prism is six inches by one inch and comes with a microfiber cloth bag to wipe off fingerprints (which will show up in your photo)....
Stunt driver Ben Collins and pro racer Matt Powers drove their cars on two separate racetracks in California. The layouts of the racetracks were identical–oblong shapes of flat, bland asphalt. But in their VR headsets, the landscape was transformed into a largely gray-scale world of crashing boulders, rubble, and steaming vents, and the drivers raced simultaneously. It’s the most intense game of Mario Kart ever. Watch the full video, full of thrilling cuts to transparent images of motor oil, below:

“Our study shows that daily cannabis use, especially of high potency cannabis, is strongly linked to the risk of developing psychosis,” lead author Marta Di Forti of King’s College London wrote in an email sent to Popular Science. The researchers define this as the risk of developing a psychotic disorder (it’s a technical term) such as schizophrenia and having symptoms such as hearing voices and experiencing delusions or paranoia. They studied 901 patients who experienced their first episode of psychosis and a further 1237 patients who had never had such an episode....
