Even in stringent times, it seems like a good idea to do some science to find out what the world is made of and how it works.

Honey bee brains could soon be helping robots act more independently. The way that bees smell and see is being studied in a £1m project to produce a simulation of the insect’s sensory systems. The simulated bee brain will then be used by a flying robot to help it make decisions about how to navigate…
Childhood abuse and maltreatment can shrink important parts of the brain, a new study of adults suggests. Reduced brain volume in parts of the hippocampus could help to explain why childhood problems often lead to later psychiatric disorders, such as depression, drug addiction and other mental health problems, the researchers say. This link could help…
A consortium of scientists announced they had made major progress in deciphering the genome of bread wheat, a vital crop whose DNA is notoriously complex. Publishing in the journal Nature, they said they had analysed between 94,000 and 96,000 genes in bread wheat (Triticum aestivum). The plant’s genome is nearly five times as big as…
The early Earth flipped back and forth between a hydrocarbon-free atmosphere and a hydrocarbon-rich one similar to that of Saturn’s moon, Titan. This ‘see-sawing’ atmosphere over 2.5 billion years ago was the result of intense microbial activity, say Newcastle University scientists, and would have had a profound effect on the climate of the Earth system….
Murder is contagious and may spread like the flu, new research suggests. The researchers relied on the same techniques public-health officials use to track the spread of diseases, but applied them to the spread of homicide in Newark, N.J., over a 26-year span from 1982 to 2008. And just as in other epidemics, certain neighborhoods…
Researchers from the University of Chicago and several international institutions found that several groups of genes in humans and dogs—including those related to diet and digestion, neurological processes, and disease—have been evolving in parallel for thousands of years. This parallel evolution was likely driven by the shared environments of humans and dogs, wrote the authors…
