April 20 (UPI) -- Scientists have adapted an optics technique used by astronomers to render biological processes at both the cellular and sub-cellular level in unprecedented detail.Researchers at the Howard Hughes Medical Institute, Boston Children's Hospital and Harvard Medical School worked together to build a next-generation microscope powered by "guide star" technology."For the first time, we are seeing life itself at all levels inside whole, living organisms," Tom Kirchhausen, a professor of cell biology and pediatrics at Harvard Medical School and a researcher at Boston Children's Hospital, said in a news release.The new microscope can be used to study almost any biological process or system in any kind of living organism.

Science
April 10 (UPI) -- Scientists at Johns Hopkins University have successfully recorded the brain activity of free flying bats.The breakthrough, detailed in the journal eLife, could help scientists study the brains of animals as they behave naturally -- untethered and free of cumbersome equipment."If you want to understand how the brain operates in the real world, you have to have the animal moving through the world in a natural way," Melville Wohlgemuth, a postdoctoral fellow at Johns Hopkins, said in a news release. "This idea of recording the brain without wires is brand new. And no one has used it to understand how an animal senses the world and reacts to that information."Until now, scientists have only been able to study the brain activity of animals as they perform basic -- and often co...

Even if you're traveling for business, it can be easy to adopt a vacation-mode mentality, dropping your usual healthy eating habits or over-eating out of boredom or travel anxiety.That'll probably lead to regrets later in the day: Opting for unhealthy snacks can result in GI upset or feeling hangry (thanks, sugar crash), points out Ginger Hultin, RDN, a Seattle-based Arivale coach.
