New research, led jointly by the University of Massachusetts Amherst and the University of North Texas, advances our understanding of how the wood in our homes and offices can release formaldehyde, a potent carcinogen, at levels that can exceed certain health limits. The findings, published recently in Green Chemistry, promise to advance public health. Their solution, for which the team has filed a patent, is an effective, low-cost way to mitigate the damage wrought by formaldehyde.

Physicists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have proposed the source of the sudden and puzzling collapse of heat that precedes disruptions that can damage doughnut-shaped tokamak fusion facilities. Coping with the source could overcome one of the most critical challenges that future fusion facilities will face and bring closer to reality the production on Earth of the fusion energy that drives the sun and stars.

For Arizona State University's Ph.D. recent graduate Julie Bethany Rakes, it all started as a failed experiment that ended up being an impactful discovery for the microbiology community. Recently in Nature Communications, Rakes and Regents' Professor Ferran Garcia-Pichel reported on a new bacterium that preys on soil cyanobacteria in biocrusts. In this publication, they describe the newly discovered predator's life cycle, attack mechanism and its ecological impact.

A new global survey of city leaders underscores pressing challenges facing municipalities, including rising inequality, extreme heat and flood risks exacerbated by climate change, and a need to rebalance transportation systems that overly favor private automobiles.

New Jersey Institute of Technology (NJIT) researchers have unveiled a new lab technique they say represents a "paradigm shift" in how pharmaceutical laboratories test and produce new protein-based drugs, such as therapeutic monoclonal antibodies being developed to treat a variety of diseases, from cancers to infectious diseases.

A new study by a research team from Arizona State University has found that climate change will dramatically increase the intensity of locust swarms, resulting in even more crops lost to insect pests and threatening food security.

NASA's moon rocket returned to the safety of its hangar Tuesday as Hurricane Ian approached Florida, its launch now unlikely before mid-November.

Soon to be in the teeth of a monster storm, anxious Tampa residents were making final preparations Tuesday ahead of potentially catastrophic Hurricane Ian, which is forecast to slam Florida's west coast with a ferocity unseen here in decades.

Every modern mammal, from a platypus to a blue whale, is descended from a common ancestor that lived about 180 million years ago. We don't know a great deal about this animal, but the organization of its genome has now been computationally reconstructed by an international team of researchers. The work is published Sept. 30 in Proceedings of the National Academy of Sciences.

At the nanoscale, the laws of classical physics suddenly become inadequate to explain the behavior of matter. It is precisely at this juncture that quantum theory comes into play, effectively describing the physical phenomena characteristic of the atomic and subatomic world. Thanks to the different behavior of matter on these length and energy scales, it is possible to develop new materials, devices and technologies based on quantum effects, which could yield a real quantum revolution that […]

Cells are constantly making decisions that lead to differentiation. For instance, cells in an embryo make a series of decisions that determine whether they will become neurons in some cases and muscle cells in others. How do cells make these decisions?

Every summer, weather forecasters blast news about African dust plumes crossing the southern United States. And to most people, it's just dust, but to researchers at Texas A&M University, it's much more.

Researchers have developed a metasurface device that can display three types of images depending on the illumination light. The three-channel device could be used as an anticounterfeiting measure or offer a new way to securely deliver encrypted information.

A study conducted at the State University of Campinas (UNICAMP) in Brazil has identified orphan genes in wild sugarcane (Saccharum spontaneum), a species with exceptional resistance to biotic stresses such as nematodes, fungi, bacteria and other pests and diseases, and abiotic stresses such as cold, drought, salinity and nutritionally deficient soil.

It's commonly said that the druids built Stonehenge. But is there any truth to this assertion?

Excessive clustering of tree species in urban forests and overreliance on introduced species may make urban forests more vulnerable to pests or disease and reduce their ecosystem benefits, a study published today in eLife shows.

Many people—including public figures such as Nobel Laureate Günter Grass, former West German chancellor Helmut Schmidt, and trade union leader Claus Weselsky—choose not to read their Stasi files. How can this behavior be explained? And what are the implications for the collective approach to remembrance and transparency in post-dictatorial societies? A study by the Max Planck Institute for Human Development and the Technical University of Dresden provides insights into these questions.

Trapped inside the shoreline of a bay, the resonant interactions of a tsunami with regular waves can prolong the tsunami disturbance. For the 2021 magnitude 7 Acapulco, Mexico earthquake and tsunami, edge waves in the bay and the short continental shelf also had a surprisingly significant effect on the tsunami's duration, according to a new study published in the Bulletin of the Seismological Society of America.

Lagria beetles have developed unusual physical traits to protect their progeny: Small invaginations on the backs of the larvae are inhabited by defensive bacteria.

The backbone or spine (or the vertebral column) can be divided into four major curves. The shapes of these curves allow our bodies to properly distribute weight in different positions and conditions, such as when sitting or bending down. However, certain spine malformations can cause these curves to deviate significantly, which may lead to chronic pain or serious disabilities.

Police in the U.S. deal with more diverse, distressed and aggrieved populations and are involved in more incidents involving firearms, but they average only five months of classroom training—the briefest among 18 countries examined in a Rutgers study.

Urban gardens and farms are on the rise in the U.S., but urban soils are sometimes contaminated from legacy pollution and industrial use. Despite this risk, there is little guidance for people growing food in urban soils on what levels of lead are safe, and existing policies vary widely between cities and states, as a new study highlights.

We all look in the mirror at least once a day to see our reflection. Mirrors are used not only in daily life but also in cutting-edge technologies such as semiconductor processing and high-resolution displays. Recently, a powerful Bragg reflection mirror based on high-index metamaterials has been developed that only reflects desired light.
