Scientists solved a critical part of the mystery of photosynthesis, focusing on the initial, ultrafast events through which photosynthetic proteins capture light and use it to initiate a series of electron transfer reactions.
As a sixth mass extinction sends shock waves through whole categories of species, modern zoos and aquariums stand as leading sources of conservation funding and safe havens for populations deemed threatened in the wild.
Scientists at the University of Alaska Fairbanks have identified a new species of thalattosaur, a marine reptile that lived more than 200 million years ago.
An advanced imaging technology developed at UC San Diego is allowing scientists unprecedented access into brain activities during intricate behaviors. The “Flyception2” has produced the first-ever picture of what happens in the brain during mating in any organism.
A Mississippi State researcher is co-leading a new network of more than 100 wildlife scientists and land managers from across the U.S. to monitor and aid birds along the Gulf of Mexico.
A recent study by the University of Kent has called for an increase in scientific surveys and collection of specimens to confirm the extinction of ultra-rare species.
A new study from the University of Delaware found high concentrations of microplastics in so-called convergence zones, the areas where the fresher water from the Delaware River meets the saltier water of the Atlantic Ocean and the surface currents converge. They found the distribution of plastics also depends on the force of the winds.
Habitat loss, pesticide use and, artificial light are the three most serious threats endangering fireflies across the globe, raising the spectre of extinction for certain species whose features render them more vulnerable to specific threats. Impacts range from loss of biodiversity to ecotourism.
A UTSA researcher has discovered that, whether in a pair or in groups, success in primate social systems may also provide insight into organization of human social life.
The profound threat of future climate change to biodiversity demands that scientists seek ever more effective ways to identify the most vulnerable species, communities, and ecosystems. In a new study, published in Nature Climate Change, an international team of scientists has shown that the most biodiverse regions on Earth are among the most vulnerable to future climate change.
Two studies from the National University of Singapore demonstrate that insects can learn from their previous experiences and adjust their future behaviour for survival and reproduction.
Agricultural advances are primary culprit of the lost prairie
For the first time in more than 50 years, a joint team of Cuban and U.S. field scientists studied the water quality of twenty-five Cuban rivers and found little damage after centuries of sugarcane production. They also found nutrient pollution in Cuba’s rivers much lower than the Mississippi River. Cuba’s shift to conservation agriculture after the collapse of the Soviet Union—and reduced use of fertilizers on cropland—may be a primary cause.
Trees are known for their great, but not unlimited, trunk height and diameter.
A new study, lead by researchers at Stockholm university and published in Science Advances, now demonstrate that the amount of methane presently leaking to the atmosphere from the Arctic Ocean is much lower than previously claimed in recent studies.
Researchers have for the first time found a connection between the immune systems of different bird species, and the various climatic conditions in which they live.
This year’s Great Backyard Bird Count begins on Valentine's Day, Friday, February 14, and continues through Monday, February 17. Volunteers from around the world count the birds they see for at least 15 minutes on one or more days of the count, and then enter their checklists at birdcount.org.
Examining the factors that affect the number of females being harvested during the bear hunting season will help Pennsylvania wildlife officials manage population.
Scientists published the first assessment of the impact that invasive hippos imported by drug lord Pablo Escobar are having on Colombian aquatic ecosystems. The hippos are changing the area’s water quality by importing large amounts of nutrients and organic material from the surrounding landscape.
A team of scientists has observed, for the first time, the presence of warm water at a vital point underneath a glacier in Antarctica—an alarming discovery that points to the cause behind the gradual melting of this ice shelf while also raising concerns about sea-level rise around the globe.
