Could key gene system discovery be suffocating corals' last gasp?

Oxygen is life, in or out of the water, raising concerns that declining ocean oxygen stores are adding an additional environmental stress to already highly vulnerable coral reef ecosystems. While the twin effects of ocean warming and acidification are well studied, until now there has been limited understanding of how the growing threat of ocean deoxygenation may impact the ability of corals to...

Researchers confirm human-to-human transmission of rare virus in Bolivia

Chapare virus, which causes haemorrhagic fevers, was transmitted to health workers in La Paz and resulted in three deaths Researchers with the US Centers for Disease Control and Prevention have discovered human-to-human transmission of a rare virus in Bolivia belonging to a family of viruses that can cause haemorrhagic fevers, such as Ebola.The news is a reminder that scientists are working to...

Biochar from agricultural waste products can adsorb contaminants in wastewater

Biochar -- a charcoal-like substance made primarily from agricultural waste products -- holds promise for removing emerging contaminants such as pharmaceuticals from treated wastewater. That's the conclusion of a team of researchers that conducted a novel study that evaluated and compared the ability of biochar derived from two common leftover agricultural materials -- cotton gin waste and guayule...

X-ray study explores potential of hepatitis C drugs to treat COVID-19

Researchers investigated the binding properties of several hepatitis C drugs to determine how well they inhibit the SARS-CoV-2 main protease, a crucial protein enzyme that enables the novel coronavirus to reproduce. Inhibiting, or blocking, the protease from functioning is vital to stopping the virus from spreading in patients with COVID-19.

Researchers quantify carbon changes in Sierra Nevada meadow soils

Meadows in the Sierra Nevada mountains are critical components of watersheds. In addition to supplying water to over 25 million people in California and Nevada, meadows contain large quantities of carbon belowground. While it has been known for some time that meadows have large quantities of soil carbon, whether meadow soils are gaining or losing carbon has remained unclear.

Solitary bees are born with a functional internal clock—unlike honeybees

Social insects like honeybees and hornets evolved from solitary bees and wasps, respectively. A common trait of many social insects is age-specific behavior: when they emerge from the pupa, workers typically specialize in around-the-clock tasks inside the darkness of the nest, starting with brood care. But they gradually shift towards more cyclic tasks away from center of the nest as they get...

Texas astronomers revive idea for 'Ultimately Large Telescope' on the moon

A group of astronomers from The University of Texas at Austin has found that a telescope idea shelved by NASA a decade ago can solve a problem that no other telescope can: It would be able to study the first stars in the universe. The team, led by NASA Hubble Fellow Anna Schauer, will publish their results in an upcoming issue of The Astrophysical Journal.

SpaceX’s Crewed Launch Continues What NASA’s Gemini Astronauts Started

We’re not sure if Jim Lovell and Buzz Aldrin were watching Sunday when SpaceX’s Crew Dragon lifted off from Pad 39A at Cape Canaveral for its first fully operational mission—but the odds are pretty good that they were. Astronauts from past eras of space travel tend to keep up with the doings in the modern one. Either way, the overall audience for the launch was...

Seafood mislabeling is having negative impacts on the marine environment

Media outlets, governments, academics, and NGOs are increasingly recognizing and documenting seafood fraud. Policies are being designed and revamped in an attempt to reduce seafood mislabeling. And, more and more groups are testing products for mislabeling. Despite the increased attention, however, we still know very little about the consequences of seafood mislabeling. Evidence for negative...

Songbird parents evict young for their own benefit

Parents, you might know the feeling. When kids get pushy and demanding, it's a tempting fantasy to shove them out of the house and let them survive on their own. Of course, we'd never put our babies in harm's way, but according to new research from the University of Illinois, many songbird parents give nestlings the boot well before they're ready.
