Astronomers with the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX), have used data from the project to make the largest, most accurate 3D map yet of the light emitted by excited hydrogen in the early universe, 9 billion to 11 billion years ago. This specific form of light, called Lyman alpha, is emitted in large quantities when hydrogen atoms are exposed to a star’s energy. That makes it a great tool for finding bright galaxies in this far-off time, which experienced a rash of star creation. However, the locations of fainter galaxies and gas, which also emit Lyman alpha, have remained largely unknown. “Observing ...

Pre-teens who struggle to control their video gaming habits are more likely to have psychotic-like experiences a year later, a new study has found. McGill University researchers and colleagues at Maastricht University found that 12-year-olds who showed signs of problematic gaming were more likely to experience mild paranoia, unusual beliefs or disturbed perceptions at age 13. “Problematic gaming means having difficulty controlling one’s amount of gaming, leading to distress or problems at school or in relationships,” said ...

WASHINGTON, March 3, 2026 — When you reach the bottom of a container of milk or honey, you might be tempted to tip the container over to get that last pesky little bit out. After all, you only need another teaspoon for that recipe, and you’re sure it’s in there! In Physics of Fluids, by AIP Publishing, researchers from Brown University present two related studies about thin film fluid flows in the kitchen: one about the relationship between how long it takes to tip the remaining liquid out of a container and its viscosity, and the other about the ideal time to wait before dumping ...

WASHINGTON, March 3, 2026 — If you’re diagnosed with breast cancer, what should you eat to ensure the best prognosis? In APL Bioengineering, by AIP Publishing, a multidisciplinary team of researchers at Princeton University conducted a study to find out. “We took the approach of building identical engineered tumors and culturing them in conditions that mimic the blood composition of patients under different dietary states,” author Celeste M. Nelson said. “We were hoping to identify dietary conditions that would slow tumor growth. Instead, we found one dietary ...

About The Study: In this cohort study of preschoolers in Canada, higher ultraprocessed foods (UPF) intake was associated with adverse behavioral and emotional symptoms by age 5. These findings suggest that replacing UPF with minimally processed foods (MPF) during the preschool years may support healthier behavioral development, with potential benefits for long-term mental health. These findings also support ongoing policy actions that promote MPF and underscore the need for early-life dietary interventions.  Corresponding Author: To contact the corresponding author, Kozeta Miliku, MD, PhD, email kozeta.miliku@utoronto.ca.

There is a clear correlation between health professionals’ use of alcohol and drugs and how they perceive that their substance use affects their work. The more they use, the worse they believe they are at taking care of their patients. Asked 3300 professionals about their substance use The research is based on data from almost 3300 doctors and nurses in Sweden, who reported having a problematic relationship with alcohol and illegal drugs. The participants were asked about their use of alcohol, cannabis and psychostimulants, ...

Tiny life forms tucked into debris from an asteroid hit could catapult to other planets – including Earth – and survive, a new Johns Hopkins University study finds. The work demonstrates that a certain hardy bacterium easily withstands extreme pressure comparable to an ejection from Mars after an asteroid hit, as well as the inhospitable conditions it would face during the ensuing interplanetary journey. The study, published today in PNAS Nexus, suggests that microorganisms can survive remarkably more extreme conditions than expected, and raises questions about origins of life. The work ...

As members of the public increasingly turn to AI chatbots to understand their world, even subtle latent biases in the underlying models could affect public understanding of the present—and past. Daniel Karell and colleagues explored the effects of both unintentional and intentional political biases in LLMs by asking 1,912 research participants to read GPT-4o and Wikipedia summaries of two 20th century historical events: the 1919 Seattle General Strike and the 1968 Third World Liberation Front student ...

Children with prenatal opioid exposure face struggles in health, education, and social well-being throughout their childhoods and teenage years, even when sociodemographic factors are factored out. The global opioid crisis has largely been viewed as a crisis of adult users, but it has also led to a rise in children exposed to opioids before birth, only some of whom are diagnosed with neonatal abstinence syndrome—essentially, withdrawal. In 2023, approximately 95,000 American infants may have been exposed to opioids in utero. Gaëlle Simard-Duplain and Jonathan Zhang analyzed two decades of linked administrative data in British Columbia for 897,668 births ...

Dogs come in all shapes and sizes: from giant fluffy Newfoundlands to tiny short-haired Chihuahuas. And many furry companions like to spend their days inside near their humans. An initial study published in ACS’ Environmental Science & Technology reports that dogs — both big and small — impact indoor air quality. The researchers found that small active dogs produced more airborne particles, but larger animals released more microbes into the air than people did. “Pets are part of our indoor environment. By quantifying what dogs add to indoor air, we can build more realistic indoor air quality and ...

It’s encouraging news for people trying to lose weight safely, especially older adults who want to drop pounds without losing bone or muscle mass.  The study, “Does time spent upright moderate the influence of a weighted vest on change in bone mineral density during weight loss among older adults,” appears in the peer-reviewed journal Frontiers in Aging. Weighted vests can provide an external load equal to the amount of weight lost. Replacing that weight by wearing a vest can:  Help the body prevent metabolic slowdown, assisting with weight-loss ...

The extremophile bacterium Deinococcus radiodurans can survive the pressures developed during ejection from Mars as a result of massive asteroid impact. Craters on the Moon and Mars show how frequently bodies in our solar system are hit by incoming material, and impacts are an important process in planetary history. Lily Zhao, K. T. Ramesh, and colleagues simulated the conditions under which a microbe might be hurled into space by the force of an impact, subjecting Deinococcus radiodurans to pressures of up to 3 GPa (30,000 times atmospheric pressure) by putting the ...

To uncover the history of our solar system, it is necessary to study the dynamic evolution of the ancient solar nebula materials. These materials interacted and coevolved with the weak but widespread magnetic field of the solar nebula, which was generated by the weakly ionized nebular gas in the protoplanetary disk. During the formation or alteration, the magnetization of these materials can become locked in for billions of years, a phenomenon known as natural remanent magnetization (NRM). NRM measurements of primordial ...

A new study details how fecal transplants from older female mice significantly improve ovarian function and fertility in young mice. The surprising results reveal a direct link between the microbiome (the collection of all bacteria and other microbes present) of the gut and ovarian health and function. “These findings suggest that there is two-way communication between the ovary and the microbiome and that this communication changes throughout life with age,” said USC Leonard Davis School of Gerontology Associate Professor Bérénice Benayoun, the study’s senior author. The study, which ...

Osaka, Japan – Diastereomers are structurally identical molecules that are not mirror images of each other. Diastereomers can have different biological activities, potencies or toxicities, which means they can influence biological systems, be separated from one another and more. To fully unlock their potential in organic chemistry, it is important to create the necessary diastereomer, but their creation is a key problem in organic synthesis. However, a team of researchers at The University of Osaka has found a novel method for creating a diastereomer not typically produced in high quantities from traditional chemical reactions. This exciting discovery ...

The devastating wildfires in northern Canada in recent years have climate consequences that go far beyond smoke and carbon dioxide released into the atmosphere, according to a new study co-authored by two NAU researchers.  The study, which looked at the various effects of fire in northern Canada and Alaska, wasn’t all bad news: The researchers found fires in Canada, when coupled with snowpack, have a net cooling effect. That cooling, however, isn’t enough to outweigh the warming effects of permafrost carbon released into the atmosphere from fires in Alaska.  The study, which NAU professor Scott Goetz called ...
