Suicide deaths during COVID-19 stay-at-home advisory in Massachusetts

Researchers assembled suicide death data for people 10 and older from January 2015 through May 2020 in this observational study and they report stable rates of suicide deaths during the COVID-19 stay-at-home advisory in Massachusetts, a finding that paralleles others following ecological disasters.

How cells 'eat' their own fluid components

Tokyo Institute of Technology
Research News Release

Autophagy is a fundamental cellular process by which cells capture and degrade their own dysfunctional or superfluous components for degradation and recycling. Recent research has revealed that phase separated droplets have a range of important functions in cells. An international collaboration between German, Norwegian, and Japanese researchers has unravelled the mechanisms underpinning both how these droplets are captured through autophagy, as well as how droplets can serve as a platform from which structures facilitating cytosolic autophagy arise.

Common pesticides stop bees and flies from getting a good night's sleep

University of Bristol
Research News Release

Just like us, many insects need a decent night's sleep to function properly, but this might not be possible if they have been exposed to neonicotinoid insecticides, the most common form of insecticide used worldwide, suggests research by academics at the University of Bristol.

Antibiotic resistance may spread even more easily than expected

Chalmers University of Technology
Research News Release

Pathogenic bacteria in humans are developing resistance to antibiotics much faster than expected. Now, computational research at Chalmers University of Technology, Sweden, shows that one reason could be significant genetic transfer between bacteria in our ecosystems and to humans. This work has also led to new tools for resistance researchers.

Spitting Cobra venom reveals how evolution often finds the same answer to a common problem

Bangor University
Research News Release

A study of spitting cobras, published in Science (22 January 2021) reveals how a combination of venom components have evolved to create an instantly painful venom, not once, but on three separate occasions. This is the first clear example of snake venom evolving for defence, and provides a remarkable example of convergent evolution, or how natural selection can cause the same solution to a problem to evolve multiple times.
