NASA and other U.S. agencies and space science institutions, along with international partners, will participate in a 'tabletop exercise' that will play out a realistic -- but fictional -- scenario for an asteroid on an impact trajectory with Earth.
Ancient fire remains provide evidence of Neanderthal group mobility and settlement patterns and indicate specific occupation episodes, according to a new study.
Biologists show that evolution is driven by dependency on other species within ecological communities - testing a long-held idea of the late, great George Gaylord Simpson.
A new study has unraveled the four decade long mystery surrounding the occurrence of a mid-sea Polynya -- a body of unfrozen ocean that appeared within a thick body of ice during Antarctica's winter almost two years ago.
Elevated concentrations of carbon dioxide in air flowing out to sea from Silicon Valley and the Salinas Valley could increase the amount of carbon dioxide dissolving in Monterey Bay waters by about 20 percent.
Researchers have found a variety of diseases and other health problems in the second- and third-generation offspring of rats exposed to glyphosate, the world's most popular weed killer. In the first study of its kind, the researchers saw descendants of exposed rats developing prostate, kidney and ovarian diseases, obesity and birth abnormalities.
Scratching the skin triggers a series of immune responses culminating in an increased number of activated mast cells -- immune cells involved in allergic reactions -- in the small intestine, according to research conducted in mice. This newly identified skin-gut communication helps illuminate the relationship between food allergy and atopic dermatitis (a type of eczema), a disease characterized by dry, itchy skin.
A recent discovery explains a new family of gravitational instabilities in granular particles of different densities that are driven by a gas-channeling mechanism not seen in fluids. The team observed an unexpected Rayleigh-Taylor (R-T)-like instability in which lighter grains rise through heavier grains in the form of 'fingers' and ''granular bubbles, similar to the bubbles that form and rise in lava lamps.
ECCITE-seq (Expanded CRISPR-compatible Cellular Indexing of Transcriptomes and Epitopes by sequencing) allows researchers to perform high-throughput measurements of multiple modalities of information from single cells. The technique profiles different types of biomolecules from thousands of single cells in parallel, offering a breadth of information that can be used as readout in CRISPR-based pooled genetics screens.
The gap between the economic output of the world's richest and poorest countries is 25 percent larger today than it would have been without global warming, according to new research.
