"This is the best evidence of water and waves that we've seen in the entire mission," said Ashwin Vasavada, Curiosity's project scientist at NASA's Jet Propulsion Laboratory in California.

More than half of Switzerland's native fish species are threatened with extinction or are already extinct within the country's waters, a new assessment showed Wednesday.

Out of 71 native fish and jawless fish, 34 are under threat of extinction in Swiss waters, like the critically-endangered European eel, and nine are no longer found within Switzerland, the Federal Office for the Environment (FOEN) said.

Young men rate their IQ as higher compared to age-matched women, but the reverse is true for older adults

Do the observed sex differences in self-estimated intelligence among younger adults extend to older adults as well? And what are some psychological correlates of self-estimated intelligence among older adults? These are the research questions pursued by a new paper published in Brain and Behavior. “I am interested in neuropsychological assessment in older people. For many years I was wondering if there is a correlation between actual cognitive performance/intellectual abilities and self-estimated performance in cognitive tasks – including intelligence tests – not only in older adults, but also...

Superbugs could kill 10 million people per year by 2050: UN

A new report out Tuesday from the U.N. Environment Program warns that as many as 10 million people could die from so-called "Superbugs" annually by 2050 as the result of antimicrobial resistance driven by environmental pollution and irresponsible practices from a range of industries.

The report, titled Bracing for Superbugs, explains how pollution from hospital wastewater, sewage discharged from pharmaceutical production facilities, and run-off from animal and plant agriculture can be rife with "not only resistant microorganisms, but also antimicrobials, various pharmaceuticals, microplastics, metals, and other chemicals, which all increase the risk of AMR [antimicrobial resistance] in the environment."

New research highlights the misinformation about misinformation research

A paper published in the journal Social Media + Society identifies six misconceptions about misinformation, highlighting some of the implicated conceptual and methodological challenges. Despite misinformation comprising a miniscule proportion of the information people consume, Americans find themselves more concerned by fake news than terrorism, online fraud and online bullying, among other issues. “I started working on misinformation during my bachelor, right after I stopped believing in various conspiracy theories,” said study author Sacha Altay, a postdoctoral researcher at the University o...

More than nine in 10 former NFL players’ brains studied at Boston University found to have CTE

More than nine in 10 brains of former NFL players examined by Boston University researchers had the harmful brain condition known as CTE, the scientists said this week. Chronic traumatic encephalopathy is a disease caused by repeated head impacts — like the ones football players experience throughout a game, season and career. It can cause memory loss, personality changes and erratic behavior among other symptoms. CTE can only be diagnosed after death. “We have 376 NFL players in the bank and we found CTE in 345, roughly 91.7 percent of them,” Dr. Ann McKee, director of the Boston University C...

Psilocybin might help reduce rumination and suppressive thoughts in depressed patients

Many doctors treat depression with SSRIs, but could psychedelic medication be more effective? A study published in BJ Psych Open suggests that psilocybin, a psychedelic substance found in “magic” mushrooms, may be more beneficial than certain antidepressants for helping improve depressive symptoms related to thought suppression and rumination. Depression is a challenging and debilitating mental illness that affects many people worldwide. Depression is characterized by many difficult symptoms and maladaptive coping mechanisms, including rumination and negative thought suppression. The most comm...

NASA prepares for what could go wrong when Artemis astronauts return to Earth

KENNEDY SPACE CENTER — The 5,000 mph reentry was a rough one and one of the four astronauts who just spent a week orbiting the moon has a spinal injury. “Backboard!” screams one of the rescue crew venturing into the Orion capsule floating in the water. That was the scenario being practiced by NASA’s Landing and Recovery team for Artemis II, which plans to fly humans beyond low-Earth orbit for the first time in more than 50 years as the first crewed mission of the Artemis program, an orbital trip around the moon and back. The launch is not slated until 2024, but teams are already prepping for a...

Chickadees, titmice and nuthatches flocking together benefit from a diversity bonus – so do other animals, including humans

Carolina chickadees are small, boisterous year-round residents of the southeastern United States. They are regularly found with much larger tufted titmice, white-breasted nuthatches and various woodpecker species.

In these mixed flocks, chickadees are almost always the subordinate individuals, outcompeted by their larger flockmates. Why, then, do chickadees regularly join these flocks? Might they have a symbiotic relationship with other species in these flocks?

Children of mothers who use cannabis are much more likely to die in the first year of life

A new analysis of hospital discharges in California showed that 1% of children whose mothers were diagnosed with the cannabis use disorder died in the first year of life. This percentage was 0.4% for mothers without this disorder. The study was published in Drug and Alcohol Dependence. Cannabis use disorder is a problematic pattern of using cannabis that leads to clinically significant impairment or distress. It is defined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) as a condition in which individuals continue to use cannabis despite experiencing negative consequences,...

Fossils in a northern Alberta riverbed may reveal new facts about dinosaur evolution

Alberta has been ground zero for dinosaur discoveries in Canada since the 1880s, when several Geological Survey of Canada expeditions collected dinosaur bones from the southern part of the province.

The most significant specimens tended to come from the badlands along the Red Deer River, including the highly productive ones in what is now aptly called Dinosaur Provincial Park.
