Striking difference between neurons of humans and other mammals
Human neurons have a lower density of ion channels than expected, compared to neurons of other mammals, according to a new study. The researchers hypothesize that a lower channel density may have helped the human brain evolve to operate more efficien.....»»
Scientists discover crude oil decimates sea otter buoyancy
Sea otters are famed for their luscious pelts, but the fur almost led to their extinction. By 1938, only a tiny population of ~50 remained clinging to the central California coast. Since then, the mammals have battled back. However, the charismatic c.....»»

Online dating sites: The size of the potential dating pool makes all the difference
Online dating sites have become one of the more popular means for people to meet each other and explore the potential for a romantic relationship. But did you know that it's the size of the online dating pool that could make or break your own quest f.....»»
Carbohydrate polymers could be a sweet solution for water purification
Water polluted with heavy metals can pose a threat when consumed by humans and aquatic life. Sugar-derived polymers from plants remove these metals but often require other substances to adjust their stability or solubility in water......»»

Cloud atlas of Mars showcases array of atmospheric phenomena
Cloud enthusiasts have a new tool to investigate striking formations in the skies above the red planet. A browsable database of 20-years-worth of images of clouds and storms, created by the German Aerospace Centre (DLR) in Berlin, is helping scientis.....»»
Thanks to humans, Salish Sea waters are too noisy for resident orcas to hunt successfully
The Salish Sea—the inland coastal waters of Washington and British Columbia—is home to two unique populations of fish-eating orcas, the northern resident and the southern resident orcas. Human activity over much of the 20th century, including red.....»»
Pollution of the potent warming gas methane soars and people are mostly to blame
The amount and proportion of the powerful heat-trapping gas methane that humans spew into the atmosphere is rising, helping to turbocharge climate change, a new study finds......»»
How viruses move through insects for transmission of diseases
Viruses are master parasites that have adapted to infect many host species. Some viruses even use multiple hosts to spread their infections—such as arboviruses that use insects to move their infections to mammalian hosts like humans. Understanding.....»»
Promoting horse welfare with an intestinal disease screening method
Researchers at the University of Jyväskylä, Finland, are developing a promising method to support the diagnosis of inflammatory bowel diseases (IBD) in horses. Awareness of the prevalence of IBD in both humans and animals has increased in recent de.....»»
A roadmap for using viruses to enhance crop performance
Humans, livestock and companion animals benefit from virus-based vaccines and gene therapies, but crops do not. This paradox is highlighted by an international research group led by the Institute of Molecular and Cellular Biology of Plants (IBMCP) wi.....»»
First robot leg with "artificial muscles" jumps nimbly: Study
Researchers said on Monday they had designed the first robotic leg with "artificial muscles"—oil-filled bags allowing machines to move more like humans—that can jump nimbly across a range of surfaces......»»
Space travel comes with risk—SpaceX"s Polaris Dawn mission will push the envelope further than ever
Space is an unnatural environment for humans. We can't survive unprotected in a pure vacuum for more than two minutes. Getting to space involves being strapped to a barely contained chemical explosion......»»
