Boosting a single molecule in the brain can change "dispositional anxiety," the tendency to perceive many situations as threatening, in nonhuman primates, researchers from the University of California, Davis, and the University of Wisconsin-Madison have found. The molecule, neurotrophin-3, stimulates neurons to grow and make new connections.
A new species of giant penguin - about 1.6 meters tall - has been identified from fossils found in Waipara, North Canterbury.
Over the past several years, microplastic particles have repeatedly been detected in sea-water, drinking water, and even in animals. But these minute particles are also transported by the atmosphere and subsequently washed out of the air, especially by snow - and even in such remote regions like the Arctic and the Alps. This was demonstrated in a study conducted by experts at the Alfred Wegener Institute and a Swiss colleague, recently published in the journal Science Advances.
An interdisciplinary team comprising members of Arts & Sciences and the McKelvey School of Engineering at Washington University in St. Louis has recently uncovered a mechanism by which a plant can be affected in a myriad of ways based on the presence of the same hormone.
Few people get their level of uric acid, a breakdown product of metabolism, measured in their blood. Based on Buck research published August 15 in PLOS Genetics, it might be time to rethink that, given that 20 percent of the population have elevated levels of uric acid, increasing their risk for gout, kidney stones, metabolic syndrome, obesity, diabetes, and early death.
Research conducted at the University of Hawaiʻi (UH) at Mānoa School of Ocean and Earth Science and Technology (SOEST) on a marine sponge in Kāneʻohe Bay, O?ahu revealed a unique feeding strategy, wherein the sponge animal acquires important components of its diet from symbiotic bacteria living within the sponge.
Artificial intelligence-powered tools are rapidly becoming more accessible, including for people in the more remote corners of the globe. This is good news for smallholder farmers, who can use handheld technologies to run their farms more efficiently, linking them to markets, extension workers, satellite images, and climate information. The technology is also becoming the first line of defense against crop diseases and pests that can potentially destroy their harvests.
Chickadees can smell! That is the news from a study out of Lehigh University, the first to document naturally hybridizing songbirds' preference for the scent of their own species.
The largest study ever conducted of its kind has identified where and how to save coral reef communities in the Indo-Pacific, according to an international group of scientists from WCS (Wildlife Conservation Society) and other conservation NGOs, government agencies, and universities. The study outlines three viable strategies that can be quickly enacted to help save coral reefs that are threatened by climate change and human impacts.
For centuries, the mental world of the mind and the physical world were treated as utterly distinct. While the movement of inanimate objects could be measured and ultimately predicted with the help of mathematics, the movement of organisms - their behavior - appeared to be shaped by different forces, under the control of the will.
ST. LOUIS - During the mating season, male treehoppers--small plant feeding insects--serenade potential mates with vibrational songs sent through plant stems. If a female treehopper's interest is sparked, a male-female duet ensues until mating occurs.
Destruction of tropical rainforests reduces many unprotected habitats to small fragments of remnant forests within agricultural lands, and to date, these remnant forest fragments have been largely disregarded as wildlife habitat.
Rivers and lakes cover just about one percent of Earth's surface but are home to one-third of all vertebrate species worldwide. At the same time, freshwater life is highly threatened.
The Devonian period, which was 419 million to 359 million years ago, is best known for Tiktaalik, the lobe-finned fish that is often portrayed pulling itself onto land.
