Gas vesicles are among the largest known protein nanostructures produced and assembled inside microbial cells. These hollow, air-filled cylindrical nanostructures found in certain aquatic microbes have drawn increasing interest from scientists due to their potential for practical applications, including as part of novel diagnostic and therapeutic tools. However, producing gas vesicles is a hard ask for cells in the lab, hindering the development of applications. In a recent study published in Nature Communications, a team of researchers led by Rice University bioengineer George Lu reports the development of a new genetic regulatory system to improve cell viability during the production ...

MIAMI — Scientists have created an AI model that forecasts moderate heat stress — a major precursor to coral bleaching — at sites along Florida’s Coral Reef up to six weeks ahead, with predictions generally accurate within one week. The study presents a site-specific, explainable machine-learning framework to support coral scientists and restoration practitioners with local reef management and emergency response planning. “This model gives coral scientists and resource managers advance notice of whether heat stress is likely to occur in a season — and, more importantly, ...

Scientists at Institute of Science Tokyo (Science Tokyo) have successfully realized the highly selective asymmetric 1,6-addition of aliphatic Grignard reagents to α,β,γ,δ-unsaturated carbonyl compounds. This new methodology employs an iron catalyst in combination with a chiral N-heterocyclic carbene ligand, which suppresses undesired side reactions and drives highly regio-, stereo-, and enantioselective alkyl migration. The achievement represents a major advance in organic synthesis, offering new opportunities for drug discovery, materials chemistry, and the fine-chemical sector.   In organic chemistry, ...

A study by UC Riverside and USC education scholars found that Black and Latino teens are significantly more adept than their white peers at detecting online disinformation—particularly content related to race and ethnicity. These youth are not only quicker to identify false claims and racist propaganda, but also more likely to verify posts with credible sources and respond with corrective, fact-based content,      the study found. According to the researchers, these skills are not being taught.  “This ...

As we age, we begin to lose the connections that wire up our brains—and neuroscientists aren’t sure why.  It is increasingly clear, though, that the loss of synapses—the flexible and adaptive relay stations central to our brains’ ability to think, learn, and remember—is central to the rise of cognitive decline and dementia in old age. Now, researchers supported by the Knight Initiative for Brain Resilience have discovered clues that may tie synapse loss to another hallmark of brain aging: the declining ability of brain cells to break down and recycle damaged proteins. Published January 21, 2026, in Nature, the study shows ...

Key Takeaways Harvard SEAS researchers have developed a mathematical framework for optimizing the design of rolling contact joints, which are made of rolling surfaces and flexible connectors. To demonstrate their method, they developed a knee-like joint that reduced misalignment by 99% compared with standard mechanisms, and a robotic gripper that could hold three times the weight of a conventionally designed gripper.  Consider the marvelous physics of the human knee. The largest hinge joint in the body, it has two rounded bones held together ...

  Prior to the establishment of the Environmental Protection Agency in 1970, Americans lived in communities awash with lead from industrial sources, paint, water supply pipes and, most significantly, tailpipe emissions. A dangerous neurotoxin that accumulates in human tissues and is linked to developmental deficits in children, environmental lead levels have come way down in the years since, and so have human exposures. The proof is in your hair. An analysis of hair samples conducted by University of Utah scientists show precipitous reductions in lead levels since 1916. “We were able to show through our hair samples what the lead concentrations ...

Markus Knaden's Odor-guided Behavior research group at the Max Planck Institute for Chemical Ecology has been studying the effects of ozone on chemical communication in insects for some time. The research team was able to show that increased ozone levels alter the mating signal in fruit flies because ozone breaks down the carbon-carbon double bonds in the insects' sex pheromones. After male flies were exposed to ozone, they were no longer able to distinguish females from other males (see press release Air ...

You check into a hotel and toss and turn all night, but your sleep improves the following night. Scientists at Nagoya University wanted to understand why this happens. Working with mice, they have identified a group of neurons that become active when an animal enters a new environment. These neurons release a molecule called neurotensin that maintains wakefulness. The effect protects them from potential dangers in unknown surroundings. The study was published in Proceedings of the National Academy of Sciences. This discovery may explain the "first ...

Some tropical land regions may warm more dramatically than previously predicted, as climate change progresses, according to a new CU Boulder study that looks millions of years into Earth’s past. Using lake sediments from the Colombian Andes, researchers revealed that when the planet warmed millions of years ago under carbon dioxide levels similar to today’s, tropical land heated up nearly twice as much as the ocean. The study was published February 2 in the Proceedings of the National Academy of Sciences.  “The tropics are ...

FOR IMMEDIATE RELEASE Researchers at the Johns Hopkins Kimmel Cancer Center have developed a novel liquid biopsy approach to identify early-stage cancers by measuring the random variation in DNA methylation patterns, rather than the absolute level of those patterns as in other liquid biopsies. The method, which utilizes a new metric called the Epigenetic Instability Index (EII), successfully distinguished — with high accuracy — patients with early-stage lung and breast cancers from healthy individuals. ...

The familiar labels “night owl” and “early bird,” long used in sleep research, don’t fully capture the diversity of human internal clocks, a new study has found. The McGill University-led study published in Nature Communications found the two sleep-wake patterns, called chronotypes, contain a total of five distinct biological subtypes, each associated with different patterns of behaviour and health. A chronotype is based on the parts of a 24-hour period when a person naturally feels most alert or ready to sleep. Previous research has linked late chronotypes to worse health outcomes, but results have often been inconsistent. ...

Current school-based mental health support for children from multilingual backgrounds can be “lost in translation” because it is reliant on good proficiency in English, a new study warns. Alongside language barriers, cultural differences and mental-health related stigma mean some aspects of the psychological therapies children can access in schools may be less effective and inaccessible for those who speak English as an additional language, The study says greater linguistic flexibility, including more ...

Moths are under threat from increasing light pollution: streetlights and other artificial light sources in cities and populated areas disrupt the orientation of these nocturnal insects, which reduces their chances of mating. Scientists have been studying the effects of streetlights on moths for years but remain largely in the dark about the underlying mechanisms. The Lightstar project aims to provide new insights. “We want to create a more detailed database on how light pollution affects the ...

Physical Chemistry applies the principles and concepts of physics to understand the basics of chemistry and explain how and why transformations of matter take place on a molecular level. One of the branches of this field focusses on understanding how molecules change in the course of a chemical reaction or process. Understanding the interactions of chiral molecules with water is crucial, given the central role that water plays in chemical and biological processes. Chiral molecules are those that, despite comprising the same atoms, cannot ...

The loss of social connectedness as people age increases the odds of cognitive-related disorders and can worsen health outcomes in older populations. But is there a direct relationship between social behavior and cognition? Subhadeep Dutta Gupta, Peter Rapp, and colleagues, from the National Institute on Aging, developed a rat model to probe social cognition in the aging brain.   As presented in their eNeuro paper, the researchers used 169 young and aged male rats to discover that while older ...

New in JNeurosci, Mary Schneider and Alexander Converse, from the University of Wisconsin-Madison, led an interdisciplinary study to explore how prenatal alcohol and stress exposure affect rhesus monkey offspring in adulthood.  Pregnant rhesus monkeys either drank moderate amounts of alcohol, experienced mild stress, or both. The researchers later assessed changes to the brain’s dopamine system and alcohol drinking in adult offspring. Prenatal stress and alcohol influenced the dopamine ...

A prevention strategy developed by Canadian researchers can reduce the risk of the most common and deadly form of ovarian cancer by nearly 80 per cent, according to a new study published today in JAMA Network Open by researchers at the University of British Columbia (UBC).  The strategy, known as opportunistic salpingectomy (OS), involves proactively removing a person’s fallopian tubes when they are already undergoing a routine ...

The idea Improvements in public health have allowed humankind to survive to older ages than ever before, but, for many people, these added golden years are not spent in good health. Aging is a natural part of life, but it is associated with a greatly increased incidence of most chronic diseases, including various cancers, diabetes, and Alzheimer’s disease. The laboratory of Kris Burkewitz, assistant professor of cell and developmental biology, wants to figure out if there is a way to break the links between the aging process and disease so that we can stay healthy longer, allowing ...

Toronto, ON, February 2, 2026 — A new study suggests that people born more recently are being diagnosed with psychotic disorders (e.g., schizophrenia) more often and at younger ages compared with people born earlier.   The study included over 12 million individuals who were born between 1960 and 2005 and followed them for new diagnoses of a psychotic disorder between 1993 and 2023. Over the study, 152,587 individuals were diagnosed with a psychotic disorder. Researchers from ICES, North York General, The Ottawa Hospital, and Bruyère Health Research Institute found that the rate of new diagnoses of psychotic disorders ...
