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...
