If native plants are going to survive climate change, they need our help to move—here’s how to do it safely

2025-03-26
March 26, 2025 AMHERST, Mass. – Many native plants in the U.S. cannot possibly move themselves fast enough to avoid climate-change driven extinction. If these native plants are going to have any chance of surviving into the future, they’ll need human help to move into adjacent areas, a process known as “managed relocation.” And yet, there’s no guarantee that a plant will thrive in a new area. Furthermore, movement of introduced plants, albeit over much larger distances, is exactly how the problem of invasive species began—think of kudzu-choked forests, wetlands taken over by purple ...

Blue pigment improves foundation makeup shades for dark skin

Blue pigment improves foundation makeup shades for dark skin
2025-03-26
SAN DIEGO, March 26, 2025 — On the shelves of makeup counters and drugstores sits an array of foundations in various olive, ivory and fair shades. But for people with darker skin tones, finding the right foundation shade can be a challenge. Dark foundations on the market often fall flat, appearing gray-like once applied on the skin. But now, researchers report a blue cosmetic color additive that gives these foundations the warmth and depth they currently lack. Gabriella Baki, associate professor of pharmaceutics and director of the cosmetic science and formulation design undergraduate program at the University of ...

A safe nuclear battery that could last a lifetime

A safe nuclear battery that could last a lifetime
2025-03-26
SAN DIEGO, March 26, 2025 — Sometimes cell phones die sooner than expected or electric vehicles don’t have enough charge to reach their destination. The rechargeable lithium-ion (Li-ion) batteries in these and other devices typically last hours or days between charging. However, with repeated use, batteries degrade and need to be recharged more frequently. Now, researchers are considering radiocarbon as a source for safe, small and affordable nuclear batteries that could last decades or longer without charging.   Su-Il In, a professor at Daegu Gyeongbuk Institute of Science & Technology, will present his results at the spring meeting of the American Chemical ...

Making sturdy, semi-transparent wood with cheap, natural materials
2025-03-26
SAN DIEGO, March 26, 2025 — Can you imagine a smartphone with a wooden touchscreen? Or a house with wooden windows? Probably not — unless you’ve heard of transparent wood. Made by modifying wood’s natural structure, this material has been proposed as a sturdy, eco-friendly plastic alternative. But wood’s biodegradability is often sacrificed in the process. Researchers are hoping to change that by creating transparent woods from almost entirely natural materials and making them electrically conductive. The researchers will present their results at the spring ...

Tadpoles try to flee dangerous virus in their pond by growing much faster than normal

Tadpoles try to flee dangerous virus in their pond by growing much faster than normal
2025-03-26
The world’s amphibians are in trouble. Because of their sensitivity to climate change, habitat loss, and pollution, they may be the canary in the coalmine for the nascent anthropogenic mass extinction. Approximately 200 amphibian species have become extinct since the 1970s, and the International Union for the Conservation of Nature estimates that 34% of the 7,296 known remaining species are likewise at risk. Another reason why amphibians are vulnerable is their susceptibility to disease. An emerging, potentially deadly disease of frogs and salamanders is ranavirus, a genus of at least seven species within the family Iridoviridae. Ranavirus can rapidly jump ...

Designing walkable neighborhoods has gained attention as a method to increase physical activity among urban populations. Moreover, highly walkable areas stimulate increased neighborhood retail sales, higher property values, and greater urban sustainability. However, only limited methods are available for improving walkability in the urban centers of highly motorized suburban cities. In the urban areas of suburban cities, increasing land-use diversity by opening a multifunctional facility is considered one of the most effective strategies for an architecture-scale intervention. Dr. Haruka Kato, ...

New study challenges the ‘monogamy-superiority myth’, as non-monogamous people report just as happy relationships and sex lives

2025-03-26
Monogamous and non-monogamous individuals report similar levels of satisfaction in both their relationships and sex lives, according to a comprehensive new meta-analysis. Published today in The Journal of Sex Research, the peer-reviewed study debunks the prevailing belief that monogamous relationships – defined as exclusive romantic and sexual commitment to one partner – are inherently superior in fostering fulfilling relationships compared to alternative structures. While monogamy has been the predominant type of relationship in much of recent Western history, many individuals choose alternative structures. Non-monogamy includes various ...

Heart attacks occur when the heart muscle is damaged by reduced blood flow from one or more arteries. They strike more than ...

Glucose revealed as a master regulator of tissue regeneration in Stanford Medicine study

2025-03-26
The sugar glucose, which is the main source of energy in almost every living cell, has been revealed in a Stanford Medicine study to also be a master regulator of tissue differentiation — the process by which stem cells give rise to specialized cells that make up all the body’s tissues. It does so not by being catabolized, or broken down, to release the energy sequestered in its chemical bonds, but instead by binding in its intact form to proteins that control which genes in the genome are made into proteins and when. The discovery of glucose’s undercover double life was so surprising the researchers ...
