A new biomarker test developed by researchers at Georgetown Lombardi Comprehensive Cancer Center and their colleagues can help predict, with up to 90 percent certainty, which chemical compounds can cause DNA damage that could lead to cancer. The study was published early online the week of December 4, 2017, in PNAS.

Timing is critical for playing a musical instrument, swinging a baseball bat, and many other activities. Neuroscientists have come up with several models of how the brain achieves its exquisite control over timing, the most prominent being that there is a centralized clock, or pacemaker, somewhere in the brain that keeps time for the entire brain.

Agriculture is the economic engine that powers the Great Plains, the vast stretch of treeless prairie that covers parts of 10 states – and where the next drought can appear with little warning.

Now there’s a powerful new tool to help provide farmers and ranchers in the arid western United States critical early indications of oncoming droughts, and its name is EDDI.

Tropical Depression Dahlia was weakening into a remnant low pressure area when the Global Precipitation Measurement mission core satellite or GPM analyzed the storm's precipitation. GPM found the center devoid of rainfall and light rainfall to the east of center.  

The first clinical study of a low-cost, hand-held jaundice detector invented by Rice University students couldn’t have come at a better time for NEST360°, an international team of scientists, doctors and global health experts preparing for a Dec. 11 competition for $100 million from the MacArthur Foundation. The money would allow the team to carry out its visionary plan to halve the number of newborn deaths in African hospitals within 10 years.

Researchers at Oxford University have discovered that peregrine falcons steer their attacks using the same control strategies as guided missiles.

NASA's Terra satellite passed over the Arabian Sea on Dec. 4 and found Tropical Cyclone Ockhi moving north as desert dust pushed into the region north of the storm.

The arrival 36 years ago of a strange bird to a remote island in the Galápagos archipelago has provided direct genetic evidence of a novel way in which new species arise.

On Nov. 23 in the journal Science, researchers from Princeton University and Uppsala University in Sweden report that the newcomer belonging to one species mated with a member of another species resident on the island, giving rise to a new species that today consists of roughly 30 individuals.

Foraging is a centuries-old practice, but many of the mushrooms in British Columbia are just now being identified through DNA sequencing and the enthusiasm of amateur collectors.

It’s no surprise that chemicals in smoke cause cancer, but a new study published in the Archives of Toxicology shows that some chemicals in cigarette smoke and industrial processes may be more dangerous than previously thought. Though most “low molecular weight polycyclic aromatic hydrocarbons” (LMW PAHs) have not been shown to cause cancer alone, the study shows that in common combinations, these chemicals can help to spark the disease.
