Decoding cosmic evolution depends on accurately predicting the complex chemical reactions in the harsh environment of space. Traditional methods for such predictions rely heavily on costly laboratory experiments or expert knowledge, both of which are resource-intensive and limited in scope. Recently, a research team developed an innovative AI tool that predicts astrochemical reactions with high accuracy and efficiency, demonstrating that deep learning techniques can successfully address data limitations in astrochemistry. Titled “A Two-Stage End-to-End Deep Learning Approach for Predicting Astrochemical Reactions,” this research was published ...

A new analysis of the bite strength of 18 species of carnivorous dinosaurs shows that while the Tyrannasaurus rex skull was optimized for quick, strong bites like a crocodile, other giant, predatory dinosaurs that walked on two legs—including spinosaurs and allosaurs—had much weaker bites and instead specialized in slashing and ripping flesh. Reported in the Cell Press journal Current Biology on August 4, these findings demonstrate that meat-eating dinosaurs followed different evolutionary paths in terms of skull design and feeding style despite their similarly gigantic sizes.   “Carnivorous dinosaurs took very different paths as they ...

In the journal Nature Ecology & Evolution, a group of researchers reveals the culprit behind sea star wasting disease, a marine epidemic that has decimated sea star populations along the west coast of North America. Understanding the cause is essential for the recovery of sea stars and their kelp forest ecosystems.   AUGUST 4, 2025 - Today in Nature Ecology & Evolution, a group of researchers reveals the cause of sea star wasting disease (SSWD). This discovery comes more than a decade after the start of the marine epidemic that has killed billions of sea stars—representing over 20 different species from Alaska to Mexico. SSWD is considered the largest marine ...

When given nutritionally matched diets, participants lost twice as much weight eating minimally processed foods compared to ultra-processed foods, suggesting that cutting down on processing could help to sustain a healthy weight long term, finds a new clinical trial led by researchers at UCL and UCLH. The study, published in Nature Medicine, is the first interventional study comparing ultra-processed food (UPF) and minimally processed food (MPF) diets in ‘real world’ conditions, as well as being ...

About The Studies: This issue of JAMA includes three studies on colorectal cancer incidence and screening among younger U.S. adults. Colorectal Cancer Incidence in US Adults After Recommendations for Earlier Screening After a stable 15-year trend, local-stage colorectal cancer (CRC) incidence increased steeply in adults ages 45 to 49 during 2019-2022, including a 50% relative increase between 2021 and 2022. This trend contrasts with consistent increases of distant-stage diagnoses in this age group and likely reflects diagnosis of prevalent asymptomatic cancer through first-time screening due to recommendations for adults to begin ...

Researchers from University of California San Diego have found that a novel treatment called regulation of cues combined with behavioral weight loss (ROC+BWL) was more effective than standard cognitive behavioral therapy (CBT) in reducing binge eating among veterans with overweight or obesity. The benefits of the new treatment were sustained even six months after treatment ended, particularly for veterans with Binge Eating Disorder (BED). The results were published in JAMA Network Open. “The study showed that our treatment could reduce binge eating more than standard therapy even after the six-month follow up,” said Kerri Boutelle, ...

Due to rapid advancement of aerospace industry, severe aerodynamic heating phenomenon results in the service temperature of thermal insulation component above 2000°C. However, common oxide thermal insulation materials cannot survive in elevated ultrahigh temperature due to their relatively low melting points. Hence, it is urgent and necessary to develop new ultrahigh-temperature insulation materials with low density, high strength, extremely low thermal conductivity, and outstanding thermal stability. As is well known, ultrahigh-temperature ceramic (UHTC) is a series of promising ultrahigh-temperature thermal ...

Over the past decade, the number of picture books that parents can read to young children about personal boundaries and saying “no” to inappropriate touching has ballooned, as attention to preventing sexual abuse grows. But many of the books contain “key gaps” in teaching concepts experts recommend to help children begin to understand consent, according to a study by a pair of Washington State University researchers. They analyzed more than 100 picture books for children ages 3-8, comparing them against key tenets of consent education and child abuse prevention identified in past research. Most of the books conveyed messages aligned with some of those tenets, such as ...
