Male northern quolls are what’s known as “suicidal reproducers,” which means they die after a single mating season, or about one year. The cause of this untimely demise was previously unknown. But now scientists believe they have the answer: sleep...

True to its name, the death cap is one of the world’s most lethal mushrooms. Each year in the United States, it kills one or two people and sickens many more, mostly those who mistake it for something edible. Its numbers also seem to be increasing; over the past few decades, the species has swept across North America, becoming particularly widespread along the West Coast, and it shows...

Human actions are changing the environment at an unprecedented rate. Plant and animal populations must try to keep up with these human-accelerated changes, often by trying to rapidly evolve tolerance to changing conditions.

Waaahhh! While babies have a natural mechanism for alerting their parents that they need a diaper change, a new sensor developed by researchers at Penn State could help workers in daycares, hospitals and other settings provide more immediate care to their charges.

A new study offers a science-based method to assess protection levels in marine protected areas (MPAs) when information on regulated human activities is limited. The study, recently published in the journal Marine Policy, provides a new technique to inform progress towards international conservation goals, including protecting 30 percent of marine areas by 2030, which was adopted in Dec. 2022 at...

A study conducted by scientists from the University of Liège and the HEDERA-22 spin-off on moon milk—a mineral deposit found in caves and used for its curative properties—has led to the discovery of a cryptic compound active against bacteria that are multi-resistant to antibiotics. This discovery is the subject of a technology transfer and a publication in the International Journal of...

Induced Pluripotent Stem Cell (iPSC) lines have become essential for determining the underlying genetic drivers of human disease. Genomes of iPSCs can be easily edited using the bacteria-based CRISPR/Cas9 technology to introduce or correct disease-associated variants.

Researchers from Princeton University have uncovered the physics of a cellular process linked to aggregation diseases, including Huntington's disease, paving the way to a deeper understanding of neurodegenerative disorders at the molecular level.

How do plants defend themselves against pathogenic microorganisms? This is a complex puzzle, of which a team of biologists from the University of Amsterdam has solved a new piece. The team, led by Harrold van den Burg, discovered that while the water pores (hydathodes) in leaves provide an entry point for bacteria, they are also an active part of the defense against these invaders. The team's...

Arginine is an amino acid naturally produced by our bodies and plentiful in the fish, meat, and nuts that we eat. But as recent research in Science Advances reveals, arginine is an essential nutrient for cancer cells too. And starving them of it could potentially render tumors more vulnerable to the body's natural immune response.

The education gap between spouses shapes wives' long-term income trajectories, but the impact varies depending on the couple's race, according to a new Western study.

Efforts to fight disease-causing bacteria by harnessing their natural predators could be undermined when multiple species occupy the same space, according to a study by Dartmouth College researchers.

Trees living in conditions where carbon dioxide (CO2) levels have been artificially elevated are likely to become more efficient in conserving water.

Some past research has suggested that falsehoods travel more quickly online than the truth and are more popular with the public, but a new study gives a more hopeful view.

Between frightening movies like "Jaws" and tales about deadly animal encounters, some fear the wild animal kingdom because of potential danger.

A new study tracked what happens in the brains of rats in real time in the brain when presented with glucose, a type of sugar, labeled with a tracer. The tracer allowed the researchers to measure this new sugar in the brain.

Scientists have discovered a new form of ice that more closely resembles liquid water than any other and may hold the key to understanding this most famous of liquids.

A team of researchers have now begun to document the actual impact of electric vehicle adoption in the first study to use real-world data to link electric cars, air pollution and health. Leveraging publicly available datasets, the researchers analyzed a 'natural experiment' occurring in California as residents in the state rapidly transitioned to electric cars, or light-duty zero emissions...

Around 12,000 years ago, the Neolithic revolution radically changed the economy, diet and structure of the first human societies in the Fertile Crescent of the Near East. With the beginning of the cultivation of cereals -- such as wheat and barley -- and the domestication of animals, the first cities emerged in a new social context marked by a productive economy. Now, a study analyses the...

Sometimes, the most complex problems can be solved with the simplest approaches. Such was the case for researchers as they tried to resolve a longstanding issue of fluid friction -- the resistance between an object moving through fluid, or conversely, a stationary object with fluid flowing around or through it. It's also known as drag.

Researchers have used single carbon atom doping to form four chemical bonds in one step. Gamma-lactams (cyclic molecules that are common in antibiotics) were easily synthetically accessible from alpha, beta-unsaturated amides (an important molecule in cancer progression). The team chemically modified an anti-seizure medication in 96% yield, highlighting the work's utility to otherwise...

An international team of researchers has developed a technique that uses liquid metal to create an elastic material that is impervious to both gases and liquids. Applications for the material include use as packaging for high-value technologies that require protection from gases, such as flexible batteries.
