Study marks major milestone for Louisiana coastal plan

A nearly $2 billion plan to divert water and sediment from the Mississippi River to rebuild land in southeastern Louisiana—considered the cornerstone of the state's efforts to protect its rapidly eroding coast—has passed a major milestone with the publication of the long-awaited Army Corps of Engineers environmental impact study.

Deeper understanding of host-dependent long-distance movement of viruses in plants

Some plant viruses systemically infect plants and cause huge losses in yield though our understanding of how systemic infections occur is largely unknown. A new study from the College of Biological Sciences at China Agricultural University provides extends our understanding of how virus-host interaction determines the systemic spread of a virus in different plant hosts.

"Magic sand" might help us understand the physics of granular matter

Tokyo, Japan - Researchers from Tokyo Metropolitan University have studied the properties of mixtures of silicone-coated "magic sand", a popular kid's toy, and normal sand. Silicone-coated sand particles were found to interact with each other only, and not with other sand particles. The team discovered that adding silicone-coated sand beyond a certain threshold leads to an abrupt change in...

One size doesn't fit all when it comes to products for preventing HIV from anal sex

After 'trying on' three placebo methods for the delivery of a rectal microbicide, study participants said they could see all of them - a douche, rectal suppository and fast-dissolving rectal insert - fitting into their daily lives. These results, which also identified the product attributes most important to participants, underscore the importance of developing a range of HIV prevention products...

Study shows cactus pear as drought-tolerant crop for sustainable fuel and food

Could cactus pear become a major crop like soybeans and corn in the near future, and help provide a biofuel source, as well as a sustainable food and forage crop? According to a recently published study, researchers from the University of Nevada, Reno believe the plant, with its high heat tolerance and low water use, may be able to provide fuel and food in places that previously haven't been able...

Small volcanic lakes tapping giant underground reservoirs

In its large caldera, Newberry volcano (Oregon, U.S.) has two small volcanic lakes, one fed by volcanic geothermal fluids (Paulina Lake) and one by gases (East Lake). These popular fishing grounds are small windows into a large underlying reservoir of hydrothermal fluids, releasing carbon dioxide (CO2) and hydrogen sulfide (H2S) with minor mercury (Hg) and methane into East Lake.

Covid fightback: the critical role of HIV experts

The speed and cooperation of the Covid response has been honed by decades of dealing with ‘the biggest pandemic the world has ever seen’When Dr Anthony Fauci spoke at the 20th International Aids Conference in Melbourne in 2014, his appearance garnered little media attention.Nearly seven years later, the HIV expert and director of the US National Institute of Allergy and Infectious Diseases has...

Uncovering hidden forever chemicals

Researchers found large quantities of previously undetectable compounds from the family of chemicals known as PFAS in six watersheds on Cape Cod using a new method to quantify and identify PFAS compounds. Exposures to some PFAS, widely used for their ability to repel heat, water, and oil, are linked to a range of health risks including cancer, immune suppression, diabetes, and low infant birth...
