Researchers have developed a molecular system for controlled release of iron. They integrated ferrocene, a molecular sandwich that encloses an iron atom, with a carbon 'nanohoop'. As a result, the system allows for the release of Fe2+ ions upon activation with benign green light. Read more ›

Getting zapped with millions of volts of electricity may not sound like a healthy activity, but for some trees, it is. A new study reports that some tropical tree species are not only able to tolerate lightning strikes, but benefit from them. The trees may have even evolved to act as lightning rods. Read more ›

Scientists have created a smart insoles prototype that can accurately measure the body's interaction with the ground, which has the potential to help athletes avoid injuries, or even assist doctors in monitoring recovery. Read more ›

Los Angeles has some of the strictest tree planting rules in the nation. These policies limit tree growth, worsen shade disparities and don't improve safety, researchers found. When researchers modeled looser planting restrictions in a lower-income neighborhood, potential tree space increased by nearly 26%. But narrow sidewalks and dense infrastructure still limited where larger, shade trees could thrive. Many of L.A.'s strict tree-spacing rules are internal guidelines -- not laws... Read more ›

People with autism are typically diagnosed by clinical observation and assessment. To deconstruct the clinical decision process, which is often subjective and difficult to describe, researchers used a large language model (LLM) to synthesize the behaviors and observations that are most indicative of an autism diagnosis. Their results show that repetitive behaviors, special interests, and perception-based behaviors are most associated with an autism diagnosis. These findings have potential to improve... Read more ›

Evolving roughly 27 different times in the long history of fish, bioluminescence -- the biological production of light -- is one of the flashier survival tools used for luring prey, communication, and recognizing potential mates among various species. In a new study a team of researchers studied the organs that produce light in Vinciguerria mabahiss, a rare species of fish from the Red Sea. This paper marks the first-ever close... Read more ›

Humans are having a highly detrimental impact on biodiversity worldwide. Not only is the number of species declining, but the composition of species communities is also changing. This is one of the largest studies ever conducted on this topic. Read more ›

Many obese people report losing pleasure in eating rich foods -- something also seen in obese mice. Scientists have now discovered the reason. Long-term high-fat diets lower levels of neurotensin in the brain, disrupting the dopamine pleasure network and decreasing the desire to eat high-fat foods. Raising neurotensin levels in mice brings back the pleasure and aids weight loss. Bringing back the pleasure could help people break the habit of... Read more ›

The body's cells respond to stress -- toxins, mutations, starvation or other assaults -- by pausing normal functions to focus on conserving energy, repairing damaged components and boosting defenses. If the stress is manageable, cells resume normal activity; if not, they self-destruct. Scientists have believed for decades this response happens as a linear chain of events: sensors in the cell 'sound an alarm' and modify a key protein, which then... Read more ›

Researchers have solved a cellular mystery that may lead to better therapies for colorectal and other types of cancer. A professor of pediatrics-developmental biology and an assistant professor of molecular, cellular, and developmental biology have shown the importance of the H3K36 methylation process in regulating plasticity and regeneration in intestinal cells.

By watching the ebb and flow of the brain's chemical signals, researchers are beginning to disentangle the molecular mechanisms underlying the intrinsic motivation to learn. In a new study of zebra finches, researchers show that a hit a dopamine tells baby birds when their song practice is paying off. The findings suggest that dopamine acts like an internal 'compass' to steer their learning when external incentives are absent. Read more ›

Interferometers, devices that can modulate aspects of light, play the important role of modulating and switching light signals in fiber-optic communications networks and are frequently used for gas sensing and optical computing. Now, applied physicists have invented a new type of interferometer that allows precise control of light's frequency, intensity and mode in one compact package. Read more ›

In 2010, a researcher was pouring over research data when he discovered something he thought was odd: His data showed that at 6 months of age, formula-fed babies born of mothers who were categorized as medically obese weighed about 5% units less fat than breastfed babies in the same dataset. That discovery struck him as unusual and led him on a research journey to better understand breast milk. Now, he's... Read more ›

Even with significant expansion in the global market for antibodies used in clinical care and research, scientists recognize that there is still untapped potential for finding new antibodies. Many proteins group together in what are called protein complexes to carry out biological functions. The traditional method of generating antibodies by immunizing animals struggles to make antibodies related to these protein complexes. Scientists have now demonstrated that fusing protein complexes together... Read more ›

Researchers explored how the characteristics of communication networks in groups (i.e., density and centralization) affected the development of shared social identity and, as a result, group performance. The study's findings can help managers and other business leaders develop strategies to enhance the performance of their teams. Read more ›
