Functional Human Tissue-Engineered Liver Generated From Stem and Progenitor Cells

humanTeli-1.jpg

A research team at Children’s Hospital Los Angeles has generated functional human and mouse tissue-engineered liver from adult stem and progenitor cells. Tissue-engineered Liver (TELi) was found to contain normal structural components such as hepatocytes, bile ducts and blood vessels.

Earth-Mass Planet Right Next Door

eso1629a-small.jpg

A potentially habitable planet – Proxima Centauri b – has been found virtually next door to Earth: about four light years away. The Weizmann Institute’s Dr. Aviv Ofir is a member of the “Pale Red Dot” project; the team found that the new planet may have balmy temperatures and liquid water, albeit a fast orbit. Can it host life? Further research is underway.

Latest Research Reveals Sitting in Traffic Jams Is Officially Bad for You

122571_web.jpg

With millions of motorists set to hit the road for the bank holiday weekend, drivers have been urged to close windows and turn off fans while in traffic jams to avoid breathing in dangerously high levels of air pollution. Latest research from the University of Surrey has shown that simple adjustment to your car's ventilation system while sitting in traffic jams can greatly affect your exposure to toxic fumes by up to 76%.

The Brain Uses Backward Instant Replays to Remember Important Travel Routes

IMG_1925_sq.jpg

Neuroscientists believe they have figured out how rats solve certain navigational problems. If there’s a “reward” at the end of the trip, specialized neurons in the hippocampus of the brain “replay” the route taken to get it, but backward. And the greater the reward, the more often the rats’ brains replay it.

GBSI Antibody Validation Workshop Gathers Key Stakeholder Groups at Asilomar To Find Actionable Solutions for Improving Reproducibility in Research

antibody-validation-2.jpg

The Global Biological Standards Institute (GBSI) targets the quality of research antibodies at a workshop at Asilomar next month in its ongoing efforts to improve reproducibility in preclinical research. Antibody Validation: Standards, Policies, and Practices brings together 100 leaders representing academia, antibody producers, pharma, funders, journals and policy makers to share perspectives, build consensus and recommend actionable solutions for improving accuracy in research antibody usage and validation. It is the first convening of all such stakeholder groups with the express purpose of developing antibody standards.

THC Makes Rats Lazy, Less Willing to Try Cognitively Demanding Tasks

New research from the University of British Columbia suggests there may be some truth to the belief that marijuana use causes laziness-- at least in rats.

Green Light: USU Biochemists Describe Light-Driven Conversion of Greenhouse Gas to Fuel

122546_web.jpg

By way of a light-driven bacterium, Utah State University biochemists are a step closer to cleanly converting harmful carbon dioxide emissions from fossil fuel combustion into usable fuels. Using the phototropic bacterium Rhodopseudomonas palustris as a biocatalyst, the scientists generated methane from carbon dioxide in one enzymatic step.

Planet Found in Habitable Zone Around Nearest Star

eso1629a.jpg

Astronomers using ESO telescopes and other facilities have found clear evidence of a planet orbiting the closest star to Earth, Proxima Centauri. The long-sought world, designated Proxima b, orbits its cool red parent star every 11 days and has a temperature suitable for liquid water to exist on its surface. This rocky world is a little more massive than the Earth and is the closest exoplanet to us — and it may also be the closest possible abode for life outside the Solar System. A paper describing this milestone finding will be published in the journal Nature on 25 August 2016.

Darwin's Theory About 'Impassable' Marine Barrier Holds True for Coral Larvae in the Pacific

122447_web.jpg

MIAMI--An international team of scientists used a state-of-the-art computer model, a high-powered supercomputer, and five billion 'virtual' coral larvae to test Charles Darwin's 1880 hypothesis that marine species cannot cross the Eastern Pacific's "impassable" marine barrier. The team, which included University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science Associate Professor Claire Paris, found that Darwin's theory still hold true today even under extreme El Niño conditions known to speed up ocean currents.

Flesh-Eating Infections in Rheumatoid Arthritis Patients Spur New Discovery

Rheumatoid arthritis patients taking medications that inhibit interleukin-1beta (IL-1beta), a molecule that stimulates the immune system, are 300 times more likely to experience invasive Group A Streptococcal infections than patients not on the drug, according to University of California San Diego School of Medicine researchers. Their study, published August 19 in Science Immunology, also uncovers a critical new role for IL-1beta as the body’s independent early warning system for bacterial infections.

Research Flights Lay the Groundwork for Teaching Unmanned Aircraft to Detect and Avoid Obstacles

IMG_2750.JPG

Virginia Tech researchers and scientists from Brigham Young University have equipped an unmanned aircraft with a newly designed radar system and optical video cameras to collect data that will help aerospace engineers develop avoidance technology. This technology will enable unmanned aircraft to accurately sense and avoid obstacles like trees, power lines, and other aircraft.
