“A bromance can be a good thing,” said lead author Elizabeth Kirby, who started work on the study while a doctoral student at UC Berkeley and continued it after assuming a postdoctoral fellowship at Stanford. “Males are getting a bad rap when you look at animal models of social interactions, because they are assumed to be instinctively aggressive. But even rats can have a good cuddle – essentially a male-male bromance – to help recover from a bad day.”
Stress can have a negative influence on the human brain, but increasingly it is the ability to withstand severe stress that is the focus of research.
To determine the course and source of the virus’s spread around the globe, a UC Berkeley researcher Michael Boots, professor of integrative biology, collaborated with colleagues at Exeter University in the UK to analyze the genomes of viruses collected from around Europe, Asia, Australia and North America.
“The key insight of our work is that the global virus pandemic in honeybees is manmade not natural,”
“What’s impressive about these cockroaches is that they can run as fast through a quarter-inch gap as a half-inch gap, by reorienting their legs completely out to the side,” said study leader Kaushik Jayaram, who recently obtained his Ph.D. from UC Berkeley and is now a postdoctoral fellow at Harvard University. “They’re about half an inch tall when they run freely, but can squish their bodies to one-tenth of an inch — the height of two stacked pennies.”
While health monitors have exploded onto the consumer electronics scene over the past decade, researchers say this device, reported in the Jan. 28 issue of the journal Nature, is the first fully integrated electronic system that can provide continuous, non-invasive monitoring of multiple biochemicals in sweat.
Paul Fine, a tropical biologist at the University of California, Berkeley, approached Biotropica with the idea for the special issue after helping organize a symposium at a 2013 meeting ATBC held in Costa Rica on white-sand forest ecology and evolution and coming away impressed by the breadth of the talks.
Scientists have found an abrupt change about 6,000 years ago in how terrestrial plant and animal species coexisted, right about the time human populations were ballooning and agriculture was spreading around the world.
The simplicity of CRISPR-Cas9 gene editing will soon make studying the genes of any organism, from the simplest slime mold to the octopus, as easy as it now is to study the genes controlling development in standard lab animals such as nematodes, fruit flies, frogs and mice.
$1.76 million over three years for a Conservation Genomics Network, led by UCLA and involving UC Berkeley’s Rasmus Nielsen as co-principal investigator and Michael Nachman, Steven Beissinger and Erica Rosenblum as co-investigators. The goal is to develop a revolutionary bioinformatics toolkit to understand changes in gene expression and how threatened populations respond to changes in their habitats and in the climate.
In 2012, UC Berkeley paleontologist Anthony Barnosky and 20 co-authors published a dire paper warning that Earth’s climate is approaching a tipping point that could irrevocably drive the planet into a scary and uncertain future.
