Rethinking biosecurity governance

Perhaps the most important lesson we can learn from the current coronavirus pandemic is how to learn future lessons without having to experience a pandemic, whether natural in origin or made by humans. To do so, we need to ...

Research sheds light on how silver ions kill bacteria

The antimicrobial properties of silver have been known for centuries. While it is still a mystery as to exactly how silver kills bacteria, University of Arkansas researchers have taken a step toward better understanding the ...

Stuttering DNA orchestrates the start of the mosquito's life

All organisms have DNA, the genetic material that provides a blueprint for life. The long double-helix-shaped DNA molecules in the body's cells are first translated into RNA molecules and then translated into proteins that ...

How do mantis shrimp find their way home?

Mantis shrimps have earned fame for their powerful punching limbs, incredibly unusual eyes, and vivid exoskeletons. And, it turns out, they're also really good at finding their way home. Through a series of painstaking experiments ...

Coronavirus: A map of Sars-CoV-2 activated proteins

What happens when the pathogen responsible for the Covid-19 pandemic, the coronavirus Sars-CoV-2, makes contact with a human bronchial cell? A group of researchers from the Universities of Bologna and Catanzaro (Italy) mapped ...

Cellular factor helps package flu genome

The viral genome of influenza A—the primary cause of seasonal flu epidemics—is composed of eight RNA segments that are each encapsulated by many copies of viral nucleoprotein (NP).

Global warming to cause 'catastrophic' species loss: study

Global warming will cause "catastrophic" biodiversity loss across the world if greenhouse gas emissions aren't curbed, with some ecosystems liable to collapse as soon as 2030, according to new research into where and when ...

Risk aversion as a survival strategy in ants

Ants are excellent navigators and always find their way back to the nest. But how do they react when an obstacle or a predator blocks their path?

Fungus application thwarts major soybean pest, study finds

The soybean cyst nematode sucks the nutrients out of soybean roots, causing more than $1 billion in soybean yield losses in the U.S. each year. A new study finds that one type of fungi can cut the nematodes' reproductive ...

New coronavirus (SARS-CoV-2) mapped out

Jean and Peter Medawar wrote in 1977 that a virus is "simply a piece of bad news wrapped up in proteins." The 'bad news' in the SARS-CoV-2 case is the new coronavirus carries its mysterious genome in the form of a very long ...
