Can we solve the riddle of the coral reef halos?

Coral reefs worldwide are threatened by a variety of human impacts. Fishing is among the most pressing threats to reefs, because it occurs on most reef systems and fundamentally alters food webs. Meanwhile, observing coral ...

Atomic beams shoot straighter via cascading silicon peashooters

To a non-physicist, an "atomic beam collimator" may sound like a phaser firing mystical particles. That might not be the worst metaphor to introduce a technology that researchers have now miniaturized, making it more likely ...

Scientists create first billion-atom biomolecular simulation

Researchers at Los Alamos National Laboratory have created the largest simulation to date of an entire gene of DNA, a feat that required one billion atoms to model and will help researchers to better understand and develop ...

New sensor detects rare metals used in smartphones

A more efficient and cost-effective way to detect lanthanides, the rare earth metals used in smartphones and other technologies, could be possible with a new protein-based sensor that changes its fluorescence when it binds ...

Microbial contaminants found in popular e-cigarettes

Popular electronic cigarette (e-cigarette) products sold in the U.S. were contaminated with bacterial and fungal toxins, according to new research from Harvard T.H. Chan School of Public Health.

Scientists create international database of women scientists

A database of women scientists that was created a year ago by a team led by a CU School of Medicine postdoctoral fellow has grown to list more than 7,500 women and is featured in an article published today in PLOS Biology.

Research on disk galaxies sheds light on movement of stars

University of Arkansas astrophysicists have taken an important step toward solving the mystery of how disk galaxies maintain the shape of their spiral arms. Their findings support the theory that these arms are created by ...

Proofreading the book of life: Gene editing made safer

The advance of science is something like the wandering of an explorer through an uncharted jungle. Often, the dense undergrowth can seem impenetrable, but at certain privileged moments, a clearing opens, and an entirely new ...

The buzz about bumble bees isn't good

While many scientists are focused on the decline of honey bees, relatively few study bumble bees. The good news is that a new study provides an estimate on bumble bee population and distributions across Michigan in the past ...

An ecological tale of two scavengers

Two species of vulture—the turkey vulture and the black vulture—are able to coexist because their respective traits reduce the need for them to compete for nutritional resources, according to a study by University of ...
