A new genetic find suggests that some people who are prone to hostility, anxiety and depression might also be hard-wired to gain weight when exposed to chronic stress, leading to diabetes and heart disease.
To protect their gut microbes during illness, sick mice produce specialized sugars in the gut that feed their microbiota and maintain a healthy microbial balance. This protective mechanism also appears to help resist or tolerate additional harmful pathogens, and its disruption may play a role in human diseases such as Crohn’s disease.
In the first months of life, when babies begin to distinguish sounds that make up language from all the other sounds in the world, they can be trained to more effectively recognize which sounds “might” be language, accelerating the development of the brain maps that are critical to language acquisition and processing.
Mobile lighting systems powered by hydrogen fuel cells are cleaner, quieter and now have a proven track record in applications such as nighttime construction, sports and entertainment events and airport operations, making them ready for commercialization and broader use.
Diazepam– used to treat anxiety and other similar conditions– has been detected in rivers across the UK and Europe, having been released from waste water treatment plants. The natural photo degradation of diazepam and similar medicines– followed by bacterial breakdown– may reduce their potentially harmful impact on the UK’s freshwater environment, a team of researchers has said.
Brine shrimp, which are sold as pets known as Sea-Monkeys, are tiny— only about half an inch long each. With about 10 small leaf-like fins that flap about, they look as if they could hardly make waves. But, get billions of similarly tiny organisms together and they can move oceans.
FEI’s Teneo VS scanning electron microscope (SEM) now offers a VolumeScope capability for life science applications. The platform integrates the company’s latest-generation SEM with VolumeScope, an in-chamber microtome analytical software, to provide fully-automated, large-volume reconstructions with improved z-axis resolution.
EDAX’s TEAM 3D IQ platform opens up the next dimension in materials characterization, allowing users to extract the maximum information from their 3-D acquisitions. Each X-ray is not only identified but also tagged with x, y and z coordinates, building a true 3-D dataset to work from.
DELMIC and Phenom-World have collaborated on the development of Delphi, an integrated correlative tabletop fluorescence and electron microscope. It is a complete solution that makes it possible to do fast correlative microscopy with unique overlay precision.
Datacolor’s CHROMACAL image calibration software now offers expanded features in delivering color accuracy for brightfield microscope images. Version 1.1 expands the software’s versatility and performance by including auto white balance, the ability to handle JPEG images and more.
Scientists have uncovered how pacemaker neurons are synchronized at dusk and dawn in order to maintain the proper functioning of their biological clocks. Their findings enhance our understanding of how sleep-wake cycles are regulated and offer promise for addressing related afflictions.
Engineers have devised a way to rapidly test hundreds of different drug-delivery vehicles in living animals, making it easier to discover promising new ways to deliver a class of drugs called biologics, which includes antibodies, peptides, RNA and DNA, to human patients.
Microsoft says the next version of its flagship operating system will be called Windows 10, as the company skips version 9 to emphasize advances it is making toward a world centered around mobile devices and Internet services.
Gov. Jerry Brown has signed legislation imposing the nation's first statewide ban on single-use plastic bags, driven to action by a buildup of litter and damage to aquatic ecosystems. A national coalition of plastic bag manufacturers immediately said it would seek a voter referendum to repeal the law, which is scheduled to take effect in July 2015.
NASA engineers are preparing to crash a former military helicopter to test how various materials affect the likelihood of injuries for occupants. A Marine helicopter has been retrofitted with three different composite subfloors for today's full-scale crash test at NASA's Langley Research Center in Hampton.
