Phys.org / Climate-risk scores guide major decisions, but underlying science is rarely open
When families decide where to buy a home, when cities approve new development, or when governments decide where to invest billions in resilience, they increasingly turn to climate-risk scores for guidance.
Phys.org / Parasite behind toxoplasmosis hides multiple distinct subtypes inside each cyst
A University of California, Riverside team of scientists has found that Toxoplasma gondii, a common parasite affecting up to one-third of the global population, is far more complex than previously believed. The findings, ...
Phys.org / A specific immune system protein may drive antibiotic tolerance
If you have had strep throat or an ear infection, there's a good chance you received amoxicillin or penicillin to effectively kill the troublesome bacteria. These drugs, which belong to a broad group of antibiotics called ...
Phys.org / How a vital DNA protection protein complex adapts to new threats without compromising its essential functions
In Lewis Carroll's "Through the Looking-Glass," Alice is stuck in a never-ending race with the Red Queen yet never gains a lead. "It takes all the running you can do to keep in the same place," the Queen says. "Though we ...
Phys.org / Trust in Ph.D. advisor can predict a good grad school experience
The advisor-advisee relationship is central to most doctoral education models. Yet not all students trust their advisors. Danfei Hu, Jonathan E. Cook and colleagues sought to examine the importance of this relationship to ...
Phys.org / Mapping cell development with mathematics-informed machine learning
The development of humans and other animals unfolds gradually over time, with cells taking on specific roles and functions via a process called cell fate determination. The fate of individual cells, or in other words, what ...
Phys.org / Spider monkeys pool their knowledge to find the best fruit
When spider monkeys want to tell others about the best fruit trees in the forest or ones they've missed, they do so by changing their social groups to share what they know, according to a new study published in the journal ...
Phys.org / Changes to cougar diets and behaviors reduce their competition with wolves in Yellowstone, study finds
A new study shows that interactions between wolves and cougars in Yellowstone National Park are driven by wolves stealing prey killed by cougars and that shifts in cougar diets to smaller prey help them avoid wolf encounters. ...
Phys.org / Aging populations could cut global water use by up to 31%, study finds
Across the world, water scarcity is emerging as one of the most pressing challenges of the 21st century. Climate change is pushing rivers and aquifers into unprecedented extremes, droughts and floods are intensifying, and ...
Phys.org / High-resolution map shows dark matter's gravity pulled normal matter into galaxies
Scientists have created the highest resolution map of the dark matter that threads through the universe—showing its influence on the formation of stars, galaxies and planets.
Phys.org / Brewing possibilities: Using caffeine to edit gene expression
What if a cup of coffee could help treat cancer? Researchers at the Texas A&M Health Institute of Biosciences and Technology believe it's possible. By combining caffeine with the use of CRISPR—a gene-editing tool known ...
Phys.org / Saltier seas in spring double the chance of extreme El Niño events, study finds
Stronger El Niño events are more likely when springtime surface waters in the western Pacific Ocean become unusually salty, a new study in Geophysical Research Letters suggests. Traditionally, scientists have focused on ...
