Culture

People--who get lost easily in the extraordinary darkness of a tropical forest--have much to learn from a bee that can find its way home in conditions 10 times dimmer than starlight. Researchers at the Smithsonian Tropical Research Institute's (STRI) research station on Barro Colorado Island in Panama and the University of Lund in Sweden reveal that sweat bees (Megalopta genalis), find their way home based on patterns in the canopy overhead using dorsal vision.

Bacteria do not sexually reproduce, but that does not stop them from exchanging genetic information as it evolves and adapts. During conjugal transfer, a bacterium can connect to another bacterium to pass along DNA and proteins. Escherichia coli bacteria, commonly called E. coli, can transfer at least one of these gene-containing plasmids to organisms across taxonomic kingdoms, including to fungi and protists.

Osaka, Japan - A team of scientists headed by SANKEN (The Institute of Scientific and Industrial Research) at Osaka University demonstrated that single virus particles passing through a nanopore could be accurately identified using machine learning. The test platform they created was so sensitive that the coronaviruses responsible for the common cold, SARS, MERS, and COVID could be distinguished from each other. This work may lead to rapid, portable, and accurate screening tests for COVID and other viral diseases.

SINGAPORE, 17 June 2021 - New details on the structure and function of a transport protein could help researchers develop drugs for neurological diseases that are better able to cross the blood-brain barrier. The findings were published in the journal Nature by researchers at Columbia University Vagelos College of Physicians and Surgeons, Duke-NUS Medical School, Weill Cornell Medicine and colleagues.

Ikoma, Japan - The katana, a Japanese sword, may be thought of solely as a weapon used by the samurai. But researchers from Japan have discovered that not only do plants wield their own katanas within their cells, they recruit them to specific locations within those cells to do their work.

Bottom Line: Genetic mutations indicative of DNA damage were associated with high red meat consumption and increased cancer-related mortality in patients with colorectal cancer.

NEW YORK (June 17, 2021)--New York City neighborhoods that had higher levels of socioeconomic disadvantage experienced more COVID-19 infections and deaths, according to Mount Sinai scientists who created a neighborhood-level COVID-19 inequity index.

The unique mechanical and optical properties found in the exoskeleton of a humble Asian beetle has the potential to offer a fascinating new insight into how to develop new, effective bio-inspired technologies.

Pioneering new research by a team of international scientists, including Professor Pete Vukusic from the University of Exeter, has revealed a distinctive, and previously unknown property within the carapace of the flower beetle - a member of the scarab beetle family.

The fast-food industry spent $5 billion on advertising in 2019, and the advertisements disproportionately targeted Black and Hispanic youth, according to new research published today by the Rudd Center for Food Policy and Obesity at the University of Connecticut. The new report, Fast Food FACTS 2021, finds that the industry's annual ad spending in 2019 increased by over $400 million since 2012, and that children and teens were viewing on average more than two fast food TV ads per day.

ANN ARBOR, Mich. - The price tag for giving birth in America may bring some families sticker shock - even for those with private insurance.

And when delivering moms require caesarians or their newborns need neonatal care, some families may spend as much as $10,000 out-of-pocket, according to a new Michigan Medicine-led study.

SPOKANE, Wash. - Many people likely lost sleep over COVID-19. A study of twins led by Washington State University researchers found that stress, anxiety and depression during the first few weeks of the pandemic were associated with less and lower quality sleep.

Ireland, June 17 2021: Popular video games have the potential to provide low-cost, easy access, effective and stigma-free support for some mental health issues, researchers at Lero, the Science Foundation Ireland Research Centre for Software, have found.

The team at Lero, a world leader in connected-health research, said video games could be used where conventional therapies are not available because of cost or location, or as an addition to traditional therapeutic treatments for depression or anxiety.

Although plexiglass barriers are seemingly everywhere these days -- between grocery store lanes, around restaurant tables and towering above office cubicles -- they are an imperfect solution to blocking virus transmission.

New York, NY (June 16, 2021) -- Immune cells that normally repair tissues in the body can be fooled by tumors when cancer starts forming in the lungs and instead help the tumor become invasive, according to a surprising discovery reported by Mount Sinai scientists in Nature in June.

It sounds like a plot from a Quentin Tarantino movie -- something sets off natural killers and sends them on a killing spree.

But instead of characters in a movie, these natural killers are part of the human immune system and their targets are breast cancer tumor cells. The triggers are fusion proteins developed by Clemson University researchers that link the two together.
