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

- 20/11/16 22:12
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...
Novel analytic approach enhances nuclear magnetic resonance signal detection in previously 'invisible' regions
- ScienceDaily
- 20/11/16 22:12
First introduced into wide use in the middle of the 20th century, nuclear magnetic resonance (NMR) has since become an indispensable technique for examining materials down to their atoms, revealing molecular structure and other details without interfering with the material itself.
X-ray study explores potential of hepatitis C drugs to treat COVID-19

- 20/11/16 22:12
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.
Making the best decision: Math shows diverse thinkers equal better results

A researcher found that networks that consisted of both impulsive and deliberate individuals made, on average, quicker and better decisions than a group with homogenous thinkers.
Researchers quantify carbon changes in Sierra Nevada meadow soils
- ScienceDaily
- 20/11/16 22:12
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.
Fish carcasses deliver toxic mercury pollution to the deepest ocean trenches

- 20/11/16 22:12
The sinking carcasses of fish from near-surface waters deliver toxic mercury pollution to the most remote and inaccessible parts of the world's oceans, including the deepest spot of them all: the 36,000-foot-deep Mariana Trench in the northwest Pacific.
New drug can improve fertility in women with reproductive health problems

Making the best decision: Math shows diverse thinkers equal better results
Whether it is ants forming a trail or individuals crossing the street, the exchange of information is key in making everyday decisions. But new Florida State University research shows that the group decision-making process may work best when members process information a bit differently.
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...

Field research has changed, and so should ethical guidelines, professor says
The old ethics rules are no longer offering adequate protection to field research subjects, according to two leading social scientists from Brown and Pennsylvania State Universities—and as a result, individual people and even entire societies are being left vulnerable to financial ruin, emotional manipulation and more.
Ice core collection at risk of being damaged or lost
The history of the world is carefully documented and kept in a freezer at Ohio State University.

Chemical injected in town's drinking water called 'an environmental injustice'
Residents of a small town that injected an unapproved chemical into their drinking water for 10 years want the chemical manufacturer and South Carolina health regulators to pay for exposing them to the unauthorized water additive.
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...
