Breaks in resistance training do not impair long-term development in strength and muscle size

A study investigated how a 10-week break from resistance training affected maximum strength and muscle size. The study found that a 10-week break halfway through 20 total weeks of strength training had little effect on development. During the break, maximal strength was better preserved than muscle size.

Building safer cities with AI: Machine learning model enhances urban resilience against liquefaction

In earthquake-prone areas like Japan, there is a need for better prediction of soil stability to mitigate liquefaction risks. Towards this end, researchers have used machine learning models, including artificial neural networks and bagging techniques, to create accurate 3D maps of bearing layers using data from 433 locations in Setagaya, Tokyo. This approach can identify stable construction sites, enhance disaster planning, and contribute to safer urban development, making cities more... Read more ›

Why langurs drink salt water

A new study shows the remarkable adaptability of the critically endangered Cat Ba langurs. Despite low genetic diversity, the langurs have retained key genetic traits that help them survive in their isolated environment on Cat Ba Island in Vietnam. One of these remarkable adaptations is the ability to drink salt water. Read more ›

Dramatic drop in marijuana use among U.S. youth over a decade (2011 to 2021)

Using a national survey of 88,183 adolescents in grades nine to 12, findings show marijuana use declined from 23.1% in 2011 to 15.8% in 2021, with first-time use before age 13 dropping from 8.1% to 4.9%. In 2021, use was highest among 12th graders (22.4%) and 11th graders (18.7%). Notably, in 2021, girls (17.8%) surpassed boys (13.6%) in reported use, reversing previous trends. While Asian, Hispanic, and white adolescents saw... Read more ›

Thin skin significantly blunts injury from puncture

Thin, stretchy skin -- like that of a pig or human -- significantly lessens the underlying damage that occurs when it's punctured. Pig skin even outperforms synthetic materials that are designed to mimic skin, a new study finds. Its special qualities, in particular its ability to dissipate the energy of a puncturing object, greatly reduce the damage to deeper tissues, researchers report. Read more ›

Lab-grown pork gets support from sorghum grain

Meat grown in a lab isn't science fiction anymore. Cultured meats have existed for over a decade, and as of 2023, you might even find lab-grown chicken in restaurants (in the U.S., at least). Now, with the literal support of plant-based scaffolds, 'clean meat' options are expanding. Researchers have created a prototype cultured pork using a new material: kafirin proteins isolated from red sorghum grain. Read more ›

Pythons can swallow even bigger prey than scientists realized

Burmese pythons can consume prey even larger than scientists realized, according to a new study. That means more animals are on the menu across southern Florida, where the nonnative, invasive snakes have decimated populations of foxes, bobcats, raccoons and other animals. Read more ›

H5N1 virus isolated from infected dairy worker is 100% lethal in ferrets, but does not appear to be circulating in nature anymore

A strain of H5N1 avian influenza virus found in a Texas dairy worker who was infected this spring was able to spread among ferrets through the air, although inefficiently, and killed 100% of infected animals in studies researchers performed with the strain earlier this year. Read more ›

Genomic variants that increase risk of kidney disease are found in nearly one-third of West Africans

A study has revealed a significant genetic risk factor for kidney disease in people from Ghana and Nigeria. Their study demonstrated that having just one risk variant in a gene known as APOL1 can significantly increase the risk of developing kidney disease. APOL1 is important for the immune system and variants of the gene are linked to increased risk of chronic kidney disease. The study is published in the New... Read more ›
