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.
As infections caused by nontuberculous mycobacteria (NTM) are rapidly increasing globally, a need exists for developing novel antibiotics and discovering the mechanism of resistance. New research reported in Zoonoses is aimed at understanding the mechanism of bedaquiline resistance in the model NTM species Mycobacterium marinum (M. marinum).
Domestic abuse allegations and convictions of parents who have perpetrated abuse are not being adequately captured by Scottish civil courts during child contact hearings, a new study by the Universities of Glasgow and Edinburgh Napier has found.
Trapped ions have previously only been entangled in one and the same laboratory. Now, teams led by Tracy Northup and Ben Lanyon from the University of Innsbruck have entangled two ions over a distance of 230 meters.
All over the world, children are being bullied by adults in school. New research now shows that these students could also be at increased risk of being bullied by their fellow students.
Planets orbiting binary stars are in a tough situation: They have to contend with the gravitational pull of two separate stars. Planetary formation around a single star like our sun is relatively straightforward compared to what circumbinary planets go through. Until recently, astronomers weren't sure they existed.
Children as young as five can display more positive associations with white children over Black children on measures of unconscious bias, and new research from York University finds this can be true even when taking into consideration kids' tendencies to favor same-gender peers. Taking an own-gender lens does, however, increase positive associations toward Black children, pointing to both the...
Small isolated wetlands that are full for only part of the year are often the first to be removed for development or agriculture, but a new study shows that they can be twice as effective in protecting downstream lake or river ecosystems than if they were connected to them.
Extreme climate events pose an ever-increasing threat to savannas around the world. However, the ability of these mixed woodland-grassland ecosystems to resist periods of drought can be improved with a higher number of browsing herbivores—i.e., animals such as kudus, springboks, and common elands that feed on woody vegetation. These help increase the amount of plant diversity and thus the...
About 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.
Hydrogen peroxide (H2O2) is an industrially important chemical with versatile applications. However, the traditional method used to produce H2O2 is energy intensive and produces significant emissions.
A new study has shown voters are more concerned about which party a politician belongs to than their position on Brexit—and this holds more sway with their future voting intentions when they encounter misinformation.
St Petersburg University scientists found an ant of the genus Manica in a piece of amber in collection of the Kaliningrad Amber Museum. Such ants had previously been found only in the mountains of Europe, the Caucasus, North America, and Japan. The scientists report that the age of the finding is about 33.9–37.8 million years. This is the most ancient and first known fossil species of this...
