Geologists determined the original orientation of many of the Mars bedrock samples collected by the Perseverance rover. The findings can give scientists clues to the conditions in which the rocks originally formed.

A comprehensive study of high-temperature superconducting magnets confirms they meet requirements for an economic, compact fusion power plant.

A vaccine against Zika virus is safe and effective when administered both before and during pregnancy, according to new research.

Childhood lead exposure, primarily from paint and water, is a significant health concern in the United States, but a new study has identified a surprising additional source of lead exposure that may disproportionately harm children: firearms. A team found an association between household firearm ownership and elevated lead levels in children's blood in 44 states, even when controlling for other major lead exposure sources.

A team has collected dozens of samples from across southeastern Colorado, and their results could help to answer an enduring mystery: What made Colorado's High Plains so high?

In a discovery that opens the door to a less invasive way of treating some serious disorders before birth, UC San Francisco scientists have found that delivering medicine through amniotic fluid is as effective as delivering it to the fetal brain via cerebrospinal fluid. The experiment was done in mice with a genetic disorder called Angelman syndrome.

Falling from the tip of a brush suspended in mid-air, an ink droplet touches a painted surface and blossoms into a masterpiece of ever-changing beauty. It weaves a tapestry of intricate, evolving patterns. Some of them resemble branching snowflakes, thunderbolts or neurons, whispering the unique expression of the artist's vision.

A perplexing problem for people with recurring urinary tract infections (UTIs) is persistent pain, even after antibiotics have successfully cleared the bacteria. Now researchers have identified the likely cause -- an overgrowth of nerve cells in the bladder.

After one of the most intense cyclones in world history tore through the Pacific island of Tanna in Vanuatu, new research showed the resilience of the island's forests.

The same weather system that led to the spread of the devastating Labor Day wildfires in 2020 brought record-breaking cold and early-season snowfall to parts of the Rocky Mountains. Now, new research is shedding light on the meteorology behind what happened and the impacts of such an extreme weather event.

An orca (killer whale) has been observed, for the first-ever time, individually consuming a great white shark -- and within just two minutes.

A research team has developed an AI technique capable of expediting the identification of materials with desirable characteristics. Using this technique, the team was able to discover high-performance water electrolyzer electrode materials free of platinum-group elements -- substances previously thought to be indispensable in water electrolysis. These materials may be used to reduce the cost of large-scale production of green hydrogen -- a next-generation energy source.

Galvanized steel containers and surfaces are used for harvested produce because of their durability, strength and lower cost compared to stainless steel. However, bacteria residing in storage containers can cause corrosion. The new coating will reduce corrosion by at least 70 percent, researchers say.

T follicular helper cells (Tfh) are essential for strong antibody-mediated reactions of our immune system during infections and vaccinations. However, if they get out of control, this can cause diseases such as autoimmunity, allergies or cancer. Researchers have investigated the underlying mechanisms of Tfh cell development in a mouse model and thus decoded their internal networking. They hope that this will lead to new strategies for the development of highly effective vaccines and new therapies to combat various diseases.

Results from a new US nationwide cohort study show that, despite strong recommendations in favor of consuming omega-3 fatty acids for optimal pregnancy outcomes and offspring health, 25% of participants reported rarely, or never eating fish during pregnancy, with fewer taking omega-3 supplements.

In a recent study, 151 human participants were pitted against ChatGPT-4 in three tests designed to measure divergent thinking, which is considered to be an indicator of creative thought.

Scientists have been examining the relationship between childhood adversity, and psychiatric decline as well as adult adversity and psychiatric and cognitive decline.

Research unearthed new information to help scientists better understand circulation patterns of ocean water around glaciers. In the summers of 2014 and 2019, a group of pioneers in glacial research attached GPS devices to 13 icebergs and tracked hourly changes in their positions as they passed through Greenland's Ilulissat Icefjord toward the ocean. Study results showed circulation in the primary fjord is greatly affected by freshwater flow from connecting tributary fjords, which is critically important to consider in circulation models.

Participants in the Framingham Heart Study who achieved higher levels of education tended to age more slowly and went on to live longer lives as compared to those who did not achieve upward educational mobility.

Putting off a burdensome task may seem like a universal trait, but new research suggests that people whose negative attitudes tend to dictate their behavior in a range of situations are more likely to delay tackling the task at hand.
