Mercury levels in tuna remain nearly unchanged since 1971, study says
Tuna is one of the most popular seafoods worldwide. But this protein-rich fish can build up high levels of methylmercury from feeding on contaminated prey, like smaller fish or crustaceans. Despite efforts to reduce mercury emissions into the environ.....»»
Rising mercury levels may contribute to declining Steller sea lion populations
A team of researchers from Texas A&M University and other institutions has made a surprising discovery about rising mercury levels in Steller sea lion pups that may have detrimental effects on the endangered species......»»
Stony coral tissue loss disease is shifting the ecological balance of Caribbean reefs
The outbreak of a deadly disease called stony coral tissue loss disease is destroying susceptible species of coral in the Caribbean while helping other, "weedier" organisms thrive—at least for now—according to a new study published in Science Adv.....»»
New study is first to use statistical physics to corroborate 1940s social balance theory
Most people have heard the famous phrase "the enemy of my enemy is my friend." Now, Northwestern University researchers have used statistical physics to confirm the theory that underlies this famous axiom. The study, "Proper network randomization is.....»»
Ice shelves fracture under weight of meltwater lakes, study shows
When air temperatures in Antarctica rise and glacier ice melts, water can pool on the surface of floating ice shelves, weighing them down and causing the ice to bend. Now, for the first time in the field, researchers have shown that ice shelves don't.....»»
Sister cities can help communities better navigate the climate crisis, research suggests
Anthropologists at Rice University suggest in a new study that establishing networks of 'sister cities' dedicated to addressing the impact of natural disasters can mitigate the devastation wrought by climate change......»»

Astronomers inspect population of young stellar objects in open cluster NGC 346
Using the James Webb Space Telescope (JWST), an international team of astronomers has explored young stellar objects (YSOs) in an open cluster known as NGC 346. The study, published April 24 on the preprint server arXiv, yields crucial information ab.....»»
"Degree of Kevin Bacon" gene provides possible basis for central players in group connectedness
A team of biologists and geneticists at the University of Toronto at Mississauga has found a possible genetic basis for a central player in group connectedness. In their study, published in the journal Nature Communications, the group conducted genet.....»»
Researchers determine large numbers of wild mountain goats are killed every year by avalanches
A multi-institutional team of animal behaviorists, snow impact specialists and biologists from Alaska, Montana, Switzerland and Canada has found that large numbers of wild mountain goats die every year in Alaska due to avalanches. For their study, th.....»»
Novel chemical tool for understanding membrane remodeling in the cell
In a study published in Proceedings of the National Academy of Sciences, Umeå researchers describe a natural product-like molecule, Tantalosin, that inhibits interaction between two proteins in complexes that reshape membranes inside the cell......»»
Study finds microbiome changes dynamically and favors important host-relevant functions
All multicellular organisms—from the simplest animal and plant organisms to humans—live in close association with a multitude of microorganisms, the so-called microbiome, which colonize their tissues and live in symbiotic relationships with the h.....»»
Novel triple drug combination effective against antibiotic-resistant bacteria
Scientists at the Ineos Oxford Institute (IOI) have found a new potential combination therapy to combat antimicrobial resistance (AMR) by targeting two key bacterial enzymes involved in resistance. The study, "The Triple Combination of Meropenem, Avi.....»»
Lego-pushing bumblebees reveal insect collaboration dynamics
A new study reveals that cooperation by bumblebees isn't simply a result of accumulated individual efforts. Rather, these miniature-brained creatures are not just hard-working pollinators, but also show signs of being master collaborators......»»
Power to the people: Aussies expect more from their local leaders
About two-thirds of Australians believe local governments should have more power than they currently do, according to a new study from The Australian National University (ANU)......»»
Positive school climate boosts high school grades, study finds
A study led by a UC Riverside graduate student has found that Latino high school students achieve higher grades when they perceive a more positive school climate and when they have a stronger sense of self-esteem......»»
Wildfires in wet African forests have doubled in recent decades, large-scale analysis finds
A new study presents the first large-scale analysis of fire patterns in West and Central Africa's wet, tropical forests. The number of active fires there typically doubled over 18 years, particularly in the Congo Basin. The increases are primarily du.....»»
Coastal hurricanes around the world are intensifying faster, new study finds
Hurricanes are among the world's most destructive natural hazards. Their ability to cause damage is shaped by their environment; conditions like warm ocean waters, guiding winds, and atmospheric moisture can all dictate storm strength......»»
Human activity is causing toxic thallium to enter the Baltic Sea, finds new study
Human activities account for a substantial amount—anywhere from 20% to more than 60%—of toxic thallium that has entered the Baltic Sea over the past 80 years, according to new research by scientists affiliated with the Woods Hole Oceanographic In.....»»
Targeting friends to induce social contagion can benefit the world, says new research
A new study co-authored by Yale sociologist Nicholas A. Christakis demonstrates that tapping into the dynamics of friendship significantly improves the possibility that a community will adopt public health and other interventions aimed at improved hu.....»»
For microscopic organisms, ocean currents act as "expressway" to deeper depths, study finds
Some of the ocean's tiniest organisms get swept into underwater currents that act as a conduit that shuttles them from the sunny surface to deeper, darker depths where they play a huge role in affecting the ocean's chemistry and ecosystem, according.....»»
