Virginia Tech scientists have discovered that incredibly small particles of an unusual and highly toxic titanium oxide found in coal smog and ash can cause lung damage in mice after a single exposure, with long-term damage occurring in just six weeks.
LEXINGTON, Ky. (Feb. 5, 2020) - A new study by University of Kentucky Markey Cancer Center researchers suggests that targeting a protein known as heat shock protein 47 (Hsp47) could be key for suppressing breast cancer metastasis.
Metastasis is when cancer cells spread from the primary tumor to surrounding tissues and distant organs in the body and is the primary cause for breast cancer mortality. It is estimated that metastasis is responsible for about 90% of breast cancer deaths.
TAMPA, Fla. (February 5, 2020)- Hundreds of years ago, colossal oysters were commonplace across much of Florida's northern Gulf Coast. Today, those oysters have disappeared, leaving behind a new generation roughly a third smaller - a massive decline that continues to have both economic and environmental impacts on a region considered by many to be the last remaining unspoiled coastlines in the Gulf.
A nuclear war, even a relatively contained conflict, wouldn't just have devastating consequences for life on land. It could also take a toll on the oceans, according to recent research led by the University of Colorado Boulder and Rutgers University.
The new study, published recently in the journal Geophysical Research Letters, explores a previously unknown link: How a clash between modern nuclear powers might shift the chemistry of the world's seas.
CHAMPAIGN, Ill. -- In a new study, researchers report they can manipulate how the brain encodes and retains emotional memories. The scientists found that focusing on the neutral details of a disturbing scene can weaken a person's later memories - and negative impressions - of that scene.
The future of computation is bright -- literally.
Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS), in collaboration with researchers at McMaster University and University of Pittsburgh, have developed a new platform for all-optical computing, meaning computations done solely with beams of light.
Table salt is a commonplace ingredient in the kitchen, but a different kind of salt is at the forefront of chemistry innovation. Low-temperature molten salts known as ionic liquids are said to be "greener" and safer than traditional solvents. According to an article in Chemical & Engineering News, the weekly newsmagazine of the American Chemical Society, ionic liquids are on the cusp of transforming how fibers, fuels and other industrial materials are made.
EAST LANSING, Mich. - If we understood the humans behind hacking incidents - and their intent - could we stop them? Research from Michigan State University reveals the importance of factoring in a hacker's motive for predicting, identifying and preventing cyberattacks.
Most people tend to focus on how to minimize the risk of a hack, from antivirus software to regularly updating computer software. While these defenses against attacks are helpful, study author and MSU criminal justice professor Thomas Holt believes it's just as important to have a strong offense.
While a piece of paper is usually flat and floppy, the same piece of paper crumpled into a wad is stiff and round. This demonstrates that scrunching changes the texture and behavior of precisely the same material -- paper.
UPTON, NY--Engineers strive to design smartphones with longer-lasting batteries, electric vehicles that can drive for hundreds of miles on a single charge, and a reliable power grid that can store renewable energy for future use. Each of these technologies is within reach--that is, if scientists can build better cathode materials.
University of Texas at Dallas researchers are breathing new life into an old MRI contrast agent by attaching it to a plant virus and wrapping it in a protective chemical cage.
A regulator of gene expression, retinoid X receptor (RXR), can boost scavenging cells in their mission to clear the brain of dead cells and debris after a stroke, thus limiting inflammation and improving recovery, according to preclinical research led by Jarek Aronowski, MD, PhD, of The University of Texas Health Science Center at Houston (UTHealth).
The discovery of RXR as a cleanup booster suggests that the molecule activating RXR could lead to discovery of a promising new therapeutic target. The study was published online this month in Stroke.

Tourists today spend thousands of dollars to explore and enjoy the lush and thriving rainforests of Guatemala.
It's hard to believe the landscape ever looked any different. But according to new research by UNLV climate scientists, the locations where those jungles exist today likely looked very different less than 9,000 years ago - a blink of an eye by geologic standards.
DURHAM, N.C. - The water filter on your refrigerator door, the pitcher-style filter you keep inside the fridge and the whole-house filtration system you installed last year may function differently and have vastly different price tags, but they have one thing in common.
They may not remove all of the drinking water contaminants you're most concerned about.
