When news about a novel coronavirus switched from a chronicle of its progress in China to headlines about a worldwide COVID-19 pandemic, Gladstone Institutes scientist Nadia Roan, PhD, was in the midst of publishing several papers on T cells and their role in HIV spread and

NASA-NOAA's Suomi NPP satellite provided forecasters with a nighttime view of Tropical Depression 13 early on Aug. 21. By 11 a.m. EDT, it had strengthened into Tropical Storm Laura.

The eastern Arctic Ocean's winter ice grew less than half as much as normal during the past decade, due to the growing influence of heat from the ocean's interior, researchers have found.

The finding came from an international study led by the University of Alaska Fairbanks and Finnish Meteorological Institute. The study, published in the Journal of Climate, used data collected by ocean moorings in the Eurasian Basin of the Arctic Ocean from 2003-2018.

Tin monosulfide (SnS) is a promising material used for next generation solar cells because of its nontoxic characteristics and abundance, in addition to its excellent photovoltaic properties. Sakiko Kawanishi and Issei Suzuki led a team that has succeeded in growing large single crystals of SnS, which can provide a pathway for the fabrication of SnS solar cells with a high conversion efficiency.

The abrupt climate warming events that occurred in Greenland during the last glacial period occurred very close in time to other rapid climate change events seen in paleoclimate records from lower latitudes, according to a new study, which reveals a near-synchronous teleconnection of climate events spanning Earth's hemispheres. The new high-resolution paleoclimate chronology, which was derived from thin layers of sedimentary cave rocks from around the world, provides a framework to improve climate change models and constrain ice-core chronologies.

Abrupt climate changes during the Last Glacial Period, some 115,000 to 11,700 years ago, happened at the same time across a region extending from the Arctic to the Southern Hemisphere subtropics, new research has revealed.

The study, led by University of Melbourne PhD student Ellen Corrick and published today in the journal, Science, found that rapid warming events over Greenland were linked to simultaneous temperature increases across continental Europe, and changes in rainfall in the Asian and South American monsoon regions.

ITHACA, N.Y. - As with actors and opera singers, when measuring magnetic fields it helps to have range.

Cornell researchers used an ultrathin graphene "sandwich" to create a tiny magnetic field sensor that can operate over a greater temperature range than previous sensors, while also detecting miniscule changes in magnetic fields that might otherwise get lost within a larger magnetic background.

There are well documented risk factors associated with developing substance use disorder across all age groups. A recent study from IUPUI found those risk factors affect age groups differently and proposes a primary prevention strategy for substance use disorder that is individualized for people within defined age groups.

NASA provided a series of photos of Hurricane Genevieve as it affected Mexico's southern Baja California peninsula. An astronaut aboard the International Space Station provided wide-angle photos of Genevieve, showing the size of the storm. Warnings and watches are in effect on Aug. 20.

La Jolla - Scientists at Scripps Research and Calibr, the institute’s drug discovery division, have discovered a molecule that can activate a natural immune-boosting protein called STING to help patients fight cancer.

The findings, which exemplify the interplay between Calibr and the basic science that makes Scripps Research a renowned center of innovation, mark a key advance in the field of oncology, as the STING protein is known for its strong antitumor properties.

 CLEVELAND--For more than 500 years, humans have mastered the art of refracting light by shaping glass into lenses, then bending or combining those lenses to amplify and clarify images either close-up and far-off. 
 

Light is notoriously fast. Its speed is crucial for rapid information exchange, but as light zips through materials, its chances of interacting and exciting atoms and molecules can become very small. If scientists can put the brakes on light particles, or photons, it would open the door to a host of new technology applications.

It's probably quite easy to relate to. You're in a lecture or meeting, avidly taking notes and engaged in the topic. You're alert and aware of what's being discussed, keen to absorb as much as you can. And then, suddenly, your thoughts drift away. You stop hearing what's being said or seeing what's being shown. You become drowsy, your eyelids start to droop, and your mind switches off.

Researchers from Tohoku University's Graduate School of Engineering have discovered a novel iron-based superelastic alloy (SEA) capable of withstanding extreme temperatures -both high and low.

SEAs are found in a wide variety of commercial applications because of their superelasticity, allowing them to regain their original shape. Superelasticity occurs when the metal undergoes deformation at the point known as critical stress.
