The journal Ethology is the first to adopt the guidelines, aimed at clarifying experimental design and the potential biases within.

A study of people in Sierra Leone suggests that the virus can lie in hiding from the immune system before re-emerging later and sparking a new response—although researchers didn’t examine whether this could make people infectious again.

Scientists across the world are closely tracking the spread of mutations in the coronavirus and investigating whether they could render current vaccines less effective.

As politicians try to schedule an end to the pandemic, scientists say the virus will stick around as an endemic disease similar to the common cold.

New data suggest that the company’s approved COVID-19 vaccine protects against different virus variants, but could be less effective against the one that originated in South Africa.

In addition to being more transmissible, the variant now dominant in the UK may be about 30 percent more deadly than previous strains, but much uncertainty remains.

An analysis of museum data and naturalists' observations finds that the number of bee species recorded has been declining since the 1990s. The first global, long-term study of bee trends adds to mounting evidence that the pollinators are in trouble worldwide.

A preprint casts doubt on vaccine effectiveness in light of certain mutations in the 501Y.V2 variant that emerged from South Africa.

Host vouchering, the practice of preserving species known to harbor infectious diseases, can be used to help determine a pathogen’s source, scientists say.

Knocking out the receptor for a lipid that causes inflammation rejuvenates macrophage metabolism and restores cognitive function in an Alzheimer’s disease model.

Autopsy studies have yet to find clear evidence of destructive viral invasion into patients’ brains, pushing researchers to consider alternative explanations of how SARS-CoV-2 causes neurological symptoms.

It’s too early to know whether the L452R version of SARS-CoV-2 is highly infectious like the B.1.1.7 UK variant that is also spreading around the US.
