Berkeley Lab scientists image cell-to-cell connections between soil microbes
The next time your Facebook stream is filled with cat videos, think about Myxococcus xanthus.The single-cell soil bacterium also uses a social network. But forget silly distractions. M. xanthus relies on its connections to avoid getting eaten and to score its next meal.
That’s the latest insight from a team of Berkeley Lab scientists. Using several imaging techniques, they saw for the first time that M. xanthus cells are connected by a network of chain-like membranes. (more…)
Dolphins can recognize their old tank mates’ whistles after being separated for more than 20 years—the longest social memory ever recorded for a non-human species.
The remarkable memory feat is another indication that dolphins have a level of cognitive sophistication comparable to only a few other species, including humans, chimpanzees and elephants. Dolphins’ talent for social recognition may be even more long-lasting than facial recognition among humans, since human faces change over time, but the signature whistle that identifies a dolphin remains stable over many decades.

UD alumna Windle sets off on professional journey with feed company
After a decade at the University of Delaware, Michelle Windle is beginning her professional career with Vita Plus, a premier agricultural feed company located in Madison, Wis. And to think that it all began with her knocking on the doors of professors in the Department of Animal and Food Sciences during her junior year as an undergraduate looking for a job.
As fate would have it, Windle ended up knocking on the door of Limin Kung Jr., the S.

I don’t know what he saw in me, but I’m glad that he did,” said Windle. (more…)
Study Finds Red Light Least Harmful, While Blue Light is Worst
COLUMBUS, Ohio –– When it comes to some of the health hazards of light at night, a new study suggests that the color of the light can make a big difference.
In a study involving hamsters, researchers found that blue light had the worst effects on mood-related measures, followed closely by white light.
But hamsters exposed to red light at night had significantly less evidence of depressive-like symptoms and changes in the brain linked to depression, compared to those that experienced blue or white light. (more…)
165 million-year-old omnivore may have had armadillo-like gait
“We finally have a glimpse of what may be the ancestral condition of all mammals, by looking at what is preserved in Megaconus. It allows us to piece together poorly understood details of the critical transition of modern mammals from pre-mammalian ancestors,” said Zhe-Xi Luo, professor of organismal biology and anatomy.
