Some recent claims have warned about a link between eating red and processed meat and the risk of developing cancer.  While vegetarians unleashed their confirmation bias in full force, they were happy to ignore the uncertainties in the evidence.

As often happens, concerns about reports, rather than data, lead to action and there have been called for new nutritional recommendations cautioning people to limit their intake of red and processed meats. A recent review in Meat Science examines the evidence and seeks to improve the foundation for future recommendations on the intake of red meat.

The Hubble Space Telescope has captured a never-before-seen break-up of an asteroid,  P/2013 R3, which has fragmented into as many as ten smaller pieces.

Although fragile comet nuclei have been seen to fall apart as they approach the Sun, nothing like the breakup of P/2013 R3 has ever been observed before in the asteroid belt.

In the War On Smart Kids Department, tiger mom mentalities may cause ethnic outcasts, say sociologists.

Smart Asian kids will be shunned for being too smart? of course not. Instead, the scholars argue, the children who don't achieve might be.  Sociologists Jennifer Lee of UC Irvine Min Zhou of Nanyang Technological University in Singapore detail in Race and Social Problems their weak observational study based on a small sample to make their headline-grabbing conclusion.

The data was surveys of 82 adult children of Chinese and Vietnamese immigrants, who were randomly selected from the survey of Immigration and Intergenerational Mobility in Metropolitan Los Angeles.

Researchers from North Carolina State University have developed a new technique that uses existing technology to allow researchers and natural resource managers to collect significantly more information on water quality to better inform policy decisions.

"Right now, incomplete or infrequent water quality data can give people an inaccurate picture of what's happening – and making decisions based on inaccurate data can be risky," says Dr. François Birgand, an assistant professor of biological and agricultural engineering at NC State and co-author of a paper describing the work. "Our approach will help people get more detailed data more often, giving them the whole story and allowing them to make informed decisions."

The banana variety Yangambi km5 produces toxic substances that kill the nematode Radopholus similis, a roundworm that infects the root tissue of banana plants – to the frustration of farmers worldwide. The finding bodes well for the Grande Naine, the export banana par excellence, which is very susceptible to the roundworms.

Scientists in Freiburg may have discovered a fundamental aggravating factor in autoimmune diseases. If B-lymphocytes lack the protein PTP1B, the cells will become hyperactive for stimulatory signals and can thus promote an autoimmune attack. This study offers an additional explanation to how B-cells regulate an immune response.

Beer drinkers know that hops are what gives the drink its bitterness and aroma. Recently, scientists reported that the part of hops that isn't used for making beer contains healthful antioxidants and could be used to battle cavities and gum disease.

A new identified some of the substances that could be responsible for these healthful effects. 

How do researchers know what color ancient fossils were when they lived?

Paleontologists studying fossilized feathers have proposed that the shapes of certain microscopic structures inside the feathers can reveal the color of ancient birds but new research finds that it is not yet possible to tell if these structures – thought to be melanosomes – are what they seem, or if they are merely the remnants of ancient bacteria.

Synthetic spider silk of fantastical, superhero strength is finally speeding toward commercial reality.

The material, which is five times stronger than steel, could be used in products from bulletproof vests to medical implants, according to an article in Chemical&Engineering News (C&EN).
