NASA's Aqua satellite captured an image of Tropical cyclone 02S and the visible image showed that the storm was getting better organized.
Tropical Cyclone 02A formed as a tropical depression in the Southern Indian Ocean on Dec. 4 and strengthened into a tropical storm.
Extensive evidence from HIV prevention research studies has firmly established that "Undetectable Equals Untransmittable," or U=U. This means that people living with HIV who achieve and maintain an undetectable viral load--the amount of virus in their blood--by taking antiretroviral therapy (ART) as prescribed do not sexually transmit HIV to others. The U.S.
Research from doctors at The Ohio State University Wexner Medical Center finds a new "virtual biopsy" allows them to definitively diagnose cysts in the pancreas with unprecedented accuracy. This means they can eliminate precancerous cysts and potentially save lives.
Rats exchange information about danger in a reciprocal fashion, and this information transfer is at least partially mediated by a brain region called the anterior cingulate cortex, according to a study published December 5 in the open-access journal PLOS Biology by Christian Keysers of the Netherlands Institute for Neuroscience and the University of Amsterdam, and colleagues.
Protocells -- artificial cells -- that are active and mimic living cells by moving independently and that are biocompatible and enzymatically active are now possible using an improved method developed by Penn State researchers.
Living cells are difficult to grow in the laboratory, so researchers sometimes work with synthetic cells, but these have had research limitations because they lack real cell characteristics.
NASA's Terra satellite captured an image of Tropical Cyclone Ambali and the visible image showed that the storm was rapidly intensifying.
Ambali formed as a tropical depression in the Southern Indian Ocean on Dec. 4 and quickly strengthened into a tropical storm. Today, Dec. 5, it has reached what is considered hurricane status in the Atlantic and Northeast Pacific.
WEST LAFAYETTE, Ind. -- What do bones and 3D-printed buildings have in common? They both have columns and beams on the inside that determine how long they last.
Now, the discovery of how a "beam" in human bone material handles a lifetime's worth of wear and tear could translate to the development of 3D-printed lightweight materials that last long enough for more practical use in buildings, aircraft and other structures.
HOUSTON - (Dec. 5, 2019) - If coral reefs are the canary to the ocean's coal mine, it's getting awfully bleak in the Gulf of Mexico.
A new study by Rice University Earth scientists asserts: Without a rapid and dramatic reduction of greenhouse gas emissions, fragile coral reefs in the Gulf of Mexico, like those around the world, face catastrophe.
The Parker Solar Probe spacecraft, which has flown closer to the Sun than any mission before, has found new evidence of the origins of the solar wind.
NASA's Parker Solar Probe was launched in August 2018. Its first results are published today in a series of four papers in Nature, with Imperial College London scientists among those interpreting some of the key data to reveal how the solar wind is accelerated away from the surface of the Sun.
A new discovery from a team led by Massachusetts Eye and Ear researchers may bring scientists a step closer to developing treatments that regrow the missing cells that cause hearing loss.
For years, researchers looking at seafloor sediments would find bits of black carbon along with organic carbon strewn across the ocean floor, but they couldn't say exactly where it originated. The challenge with studying deep marine carbon is that it is a mixture of fresh material delivered from the surface and an aged component, the origin of which had been previously unknown.
WASHINGTON -- For the first time, researchers have used a chip-based sensor with an integrated laser to detect very low levels of a cancer protein biomarker in a urine sample. The new technology is more sensitive than other designs and could lead to non-invasive and inexpensive ways to detect molecules that indicate the presence or progression of a disease.
In August 2018, NASA's Parker Solar Probe launched to space, soon becoming the closest-ever spacecraft to the Sun. With cutting-edge scientific instruments to measure the environment around the spacecraft, Parker Solar Probe has completed three of 24 planned passes through never-before-explored parts of the Sun's atmosphere, the corona. On Dec. 4, 2019, four new papers in the journal Nature describe what scientists have learned from this unprecedented exploration of our star -- and what they look forward to learning next.
Access to abundant, clean, water for drinking, recreation and the environment is one of the 21st century's most pressing issues. Directly monitoring threats to the quality of fresh water is critically important, but because current methods are costly and not standardized, comprehensive water quality datasets are rare. In the United States, one of the most data-rich countries in the world, fewer than 1% of all bodies of fresh water have ever been sampled for quality.
PULLMAN, Wash. - Resembling an overgrown house cat with black-tipped ears and a stubby tail, the Canada lynx, a native of North America, teeters on the brink of extinction in the U.S. The few lynx that now roam parts of Washington and the mountainous Northwest survive largely because of a network of protected landscapes that crosses the U.S.-Canada border.
Washington State University environmental researchers believe this transboundary landscape provides not only essential habitat for the wild cats but likely also vital connections with larger lynx populations in Canada.
