Powerful mathematical model greatly improves predictions for species facing climate change
UCLA life scientists and colleagues have produced the most comprehensive mathematical model ever devised to track the health of populations exposed to environmental change.
The research, federally funded by the National Science Foundation, is publis…
Are doing harm and allowing harm equivalent? Ask fMRI
People typically say they are invoking an ethical principle when they judge acts that cause harm more harshly than willful inaction that allows that same harm to occur. That difference is even codified in crimin…
Abrupt permafrost thaw increases climate threat
As the Arctic warms, greenhouse gases will be released from thawing permafrost faster and at significantly higher levels than previous [...]
They call it guppy love

Homoplasy: A good thread to pull to understand the evolutionary ball of yarn
With the genetics of so many organisms that have different traits yet to study, and with the techniques for gathering full sets of genetic information from organisms rapidly evolving, the “forest” of evolution can be easily lost to the “trees”…
Redesign of US donor-liver network could boost transplants by several hundred per year
PITTSBURGH — A redesign of the nation’s donor-liver distribution network developed by University of Pittsburgh researchers could result in several hundred more people each year receiving the transplants they need.
The team reports in the jour…
Kent State geology professor and research team present findings studying drought
A group of researchers have studied the history of drought in the Pacific Northwest during the last 6,000 years, a time that spans the mid-Holocene geological epoch to the present. The goal of the research was to improve the understanding of d…
Oldest fossils of large seaweeds, worm-like animals tell story of ancient oxygen
Almost 600 million years ago, before the rapid evolution of life forms known as the Cambrian explosion, a community of seaweeds and worm-like animals lived in a quiet deep-water niche near what is now Lantian, a small village in south China.

New finding in ribosome signaling may lead to improved antibiotics
Researchers at the University of Illinois at Chicago have discovered a signaling mechanism in the bacterial ribosome that detects proteins that activate genes for antibiotic resistance.
“The ribosome is one of the most complex molecular machines i…
Gender gap: Selection bias snubs scholarly achievements of female scientists
Women scientists must confront sexism when competing for awards that recognize their research, according to a new analysis.
Research funded by the National Science Foundation and sponsored by the Association for Women in Science found that female …
