Researchers describe the biology of three families of RNA viruses including Coronavirus, Ebola, and Zika and the natural products that have been shown to have capabilities to inhibit them. The review provides a guide that could accelerate drug discovery in response to future epidemics.
Hotels that promote women perceived as fairer, less discriminatory
Hotel managers have something in common beyond their reputations for charming dispositions and excellent listening skills—they're predominantly men, despite women making up the majority of the accommodations workforce. New research led by the University of Houston Conrad N. Hilton College of Hotel and Restaurant Management suggests hotel companies that promote a woman over an equally qualified...
NASA's first mission to the Trojan asteroids integrates its second scientific instrument
NASA's Lucy mission is one step closer to launch as L'TES, the Lucy Thermal Emission Spectrometer, has been successfully integrated on to the spacecraft.
Identifying Canada's key conservation hot spots highlights problem
To stop biodiversity loss, Canada recently committed to protecting 30% of its land and sea by 2030. But making conservation decisions about where to locate new protected areas is complicated. It depends on data both about biodiversity and about a range of benefits (e.g. freshwater, climate regulation, recreation) that people get from nature. Surprisingly, despite the size of the country, new...
Some English bulldogs thought to have cancer may have newly identified syndrome
Some English bulldogs diagnosed with a common cancer may instead have a newly described, non-cancerous syndrome called polyclonal B‐cell lymphocytosis. The discovery was made by Morris Animal Foundation-funded researchers at Colorado State University during a study to better understand B-cell chronic lymphocytic leukemia (BCLL). The team published their findings in the Journal of Veterinary...
Two months at sea to explore the Southern Ocean's contribution to climate regulation
A team coordinated by two CNRS researchers and involving colleagues from Sorbonne University, Toulouse III–Paul Sabatier University, the University of Western Brittany and Aix-Marseille University, will traverse the Southern Ocean from January 11 to March 8, 2021, aboard the Marion Dufresne II research vessel chartered by the French Oceanographic Fleet. Their goal is to better understand the...

The Guardian view on Boris Johnson's mutant virus plan: needs more than PR | Editorial
The prime minister aims to be credible rather than accountable in a time of Covid. That’s a mistakeIt was during the Vietnam war that the euphemism “credibility gap” was coined to describe the Lyndon Johnson administration. The phrase was used instead of saying what everyone thought – that the US government was systematically lying. The president’s team reasoned that to restore...
This avocado armchair could be the future of AI
With GPT-3, OpenAI showed that a single deep-learning model could be trained to use language in a variety of ways simply by throwing it vast amounts of text. It then showed that by swapping text for pixels, the same approach could be used to train an AI to complete half-finished images. GPT-3 mimics how humans use words; Image GPT-3 predicts what we see.
Now OpenAI has...
Routine eye scans may give clues to cognitive decline in diabetes
- ScienceDaily
- 21/1/5 19:57
As they age, people with diabetes are more likely to develop Alzheimer's disease and other cognitive disorders than are people without diabetes. Scientists now have shown that routine eye imaging can identify changes in the retina that may be associated with cognitive disorders in older people with type 1 diabetes. These results may open up a relatively easy method for early detection of cognitive...

Retracted scientific paper persists in new citations, study finds
A small portion of scientific papers are retracted for research that is in error or fraudulent. But those papers can continue to be cited by other scientists in their work, potentially passing along the misinformation from the retracted articles.
Climate change caused mangrove collapse in Oman
Most of the mangrove forests on the coasts of Oman disappeared about 6,000 years ago. Until now, the reason for this was not entirely clear. A current study of the University of Bonn (Germany) now sheds light on this: It indicates that the collapse of coastal ecosystems was caused by climatic changes. In contrast, falling sea level or overuse by humans are not likely to be the reasons. The speed...
