A sophisticated system guides the development of our limbs. Researchers have shed new light on the genetic toolkit used during evolution to create a range of different extremities such as fins, wings, hooves, toes and fingers.
Science backs nature as key to children’s health
The presence of greenspaces near homes and schools is strongly associated with improved physical activity and mental health outcomes in kids, according to a massive review of data from nearly 300 studies.
From recycling to upcycling: A smarter way of dealing with plastic
Researchers have developed a clean and cost-effective way to upcycle used plastic, transforming it into valuable nanomaterials and high-quality fuel.
How high-fat diets allow cancer cells to go unnoticed
The immune system relies on cell surface tags to recognize cancer cells. Researchers discovered mice who ate high-fat diets produced less of these tags on their intestinal cells, suppressing the ability of immune cells to identify and eliminate intestinal tumors. The high-fat diet also reduced the presence of certain bacteria...
Zebrafish anticipate the future to avoid virtual danger
Scientists have discovered particular neurons in the brain that monitor whether predictions made by fish actually come true. By making use of a new virtual reality-outfitted aquarium where brain imaging of zebrafish can be done as they learn and navigate through virtual reality cues, researchers found neurons that allow efficient...
Two new species of large predatory dinosaur discovered on Isle of Wight, UK
Bones found on the Isle of Wight likely belong to two new species of spinosaurid, a group of predatory theropod dinosaurs closely related to the giant Spinosaurus. Their unusual, crocodile-like skulls helped the group expand their diets, allowing them hunt prey on both land and in the water.
Plasmodium falciparum evolving to escape malaria rapid diagnostics in Africa
A major tool against malaria in Africa has been the use of rapid diagnostic tests, which have been part of the 'test-treat-track' strategy in Ethiopia, the second most-populated country in Africa. But researchers studying blood samples from more than 12,000 individuals in Ethiopia now estimate these tests missed nearly 10%...
Small but mighty: Microgreens go from trendy vegetables to functional food
Starting decades ago as fashionable, high-value gourmet greens, today microgreens have gained popularity among consumers for their nutritional profile and high content of antioxidant compounds. Now, a new study suggests that the tiny plants have the potential to help provide global nutrition security.
Elephants strive to cooperate with allies, until the stakes get too high
Asian elephants are keen to cooperate with friends and have evolved strategies to mitigate competition in their social groups, but cooperation breaks down when food resources are limited, according to new research. The study sheds light on the evolution of cooperative behavior in mammals.
Reducing salt in bread without sacrificing taste
Most people in the U.S. consume too much salt; adult Americans typically eat twice the daily amount recommended by dietary guidelines. Bread may not seem like an obvious culprit; however, due to high consumption and relatively high salt content, baked goods are a major source of sodium in the diet....
