High levels of biodiversity in aquatic settings offers a wide range of vitamins, minerals, and fatty acids crucial for human health, a range of nutrients that are lacking in ecosystems where the number of species have been reduced by overfishing, pollution, or climate change, researchers report April 5 in the journal Proceedings of the National Academy of Sciences.

A new Veterans Affairs study finds that combat experience is associated with a higher risk of alcohol use to cope with PTSD symptoms. But the connection is weaker when accounting for the severity of the PTSD.

The findings appeared online in the Journal of Dual Diagnosis in March 2021.

Nanographene is flexible, yet stronger than steel. With unique physical and electronic properties, the material consists of carbon molecules only one atom thick arranged in a honeycomb shape. Still early in technological development, current fabrication methods require the addition of substituents to obtain a uniform material. Additive-free methods result in flimsy, breakable fibers--until now.

Few compounds are as important to industry and medicine today as titanium dioxide. Despite the variety and popularity of its applications, many issues related to the surface structure of materials made of this compound and the processes taking place therein remain unclear. Some of these secrets have just been revealed to scientists from the Institute of Nuclear Physics of the Polish Academy of Sciences. It was the first time they had used the SOLARIS synchrotron in their research.

UConn researcher Paulo Verardi, associate professor of pathobiology and veterinary science in the College of Agriculture, Health and Natural Resources, has demonstrated the success of a vaccine against Zika virus and recently published his findings in Scientific Reports, a Nature Research publication.

Niigata, Japan - Cancer is the world's second deadliest disease which contributes towards the fatality of over 10 million people per year. Oncologists adopt a variety of treatment procedures to treat cancer cells. Among the different methods used to fight cancer, chemotherapeutic treatment is a prominent and well-adopted technique. It is a drug based method, wherein powerful chemical compounds are injected into the body to annihilate the malignant cells.

The nucleus is the headquarters of a cell and molecules constantly move across the nuclear membrane through pores. The transport of these molecules is both selective and fast; some 1,000 molecules per second can move in or out. Scientists from the University of Groningen and Delft University of Technology, both in the Netherlands, and a colleague from the Swedish Chalmers University of Technology, have developed an artificial model of these pores using simple design rules, which enabled them to study how this feat is accomplished.

Swansea University physicists, as leading members of the ALPHA collaboration at CERN, have demonstrated laser cooling of antihydrogen atoms for the first time. The groundbreaking achievement produces colder antimatter than ever before and enables an entirely new class of experiments, helping scientists learn more about antimatter in future.

Since early in the COVID-19 pandemic, parents, teachers, and school administrators have faced difficult questions regarding when and how to safely reopen for in-person learning. During the 2020-2021 fall semester, school districts around the United States navigated their reopening plans -- many opting for exclusively online learning or hybrid models -- with little data on how SARS-CoV-2 spreads among children or how in-person learning would impact transmission in the schools' communities.

A researcher from Skoltech and his German colleagues have developed a neural network-based classification algorithm that can use data from an apple orchard to predict how well apples will fare in long-term storage. The paper was published in Computers and Electronics in Agriculture.

The younger generations are willing to put their money where their mouth is when it comes to sustainable living. In a study questioning both commitment to sustainable behaviors and willingness to trade better pay to work for a more sustainable-minded company, the surveyed young adults in Japan made their preferences clear.

Japan is a country known for its continuous quality improvement (KAIZEN) in manufacturing. Now doctors are bringing this philosophy to the medical field. In pediatric intensive care units (PICU), quality improvement (QI) is needed to ensure complex medical care is provided to critically ill patients in a timely manner.

LOS ALAMOS, N.M., March 29, 2021—A first-of-its-kind instrument that samples smoke from megafires and scans humidity will help researchers better understand the scale and long-term impact of fires—specifically how far and high the smoke will travel; when and where it will rain; and whether the wet smoke will warm the climate by absorbing sunlight.

In a joint effort, researchers from the Humboldt-Universität (Berlin), the Max Born Institute (Berlin) and the University of Central Florida (USA), have revealed the necessary conditions for the robust transport of entangled states of two-photon light in photonic topological insulators, paving the way the towards noise-resistant transport of quantum information. The results have appeared in Nature Communications.

A study examining bean productivity among smallholder farmers in Tanzania, has found that on average, yields are 6% lower among female than male farmers. Women are often 'invisible' in agriculture, researchers say, due to social structural barriers and national agricultural policies, which do not address discriminatory land rights; education and agricultural information and decision making, which must be tackled to reverse this trend.
