A sulfur-oxidizing bacterial group called SUP05 will play an increasingly important role in carbon and nutrient cycling in the world's oceans as oxygen minimum zones expand, according to research published this week in the Proceedings of the National Academy of Sciences.
University of British Columbia researchers plumbed the depth of a seasonally anoxic fjord, Canada's Saanich Inlet, to chart how microbial community metabolism changes as oxygen minimum zones form.
A researcher from Moscow Institute of Physics and Technology, Prof. Vladimir Krasnopolsky, who heads the Laboratory of High Resolution Infrared Spectroscopy of Planetary Atmospheres, has published the results of the comparison of his model of Titan's atmosphere with the latest data.
FALLS CHURCH, Va. -- U.S. workplaces may need to consider innovative methods to prevent fatigue from developing in employees who are obese. Based on results from a new study published in the Journal of Occupational and Environmental Hygiene (JOEH), workers who are obese may have significantly shorter endurance times when performing workplace tasks, compared with their non-obese counterparts.
Animals can use varying sensory modalities for orientation, some of which might be very different from ours. Some bird species for example take the polarization pattern produced by sunlight in the atmosphere to calibrate their orientation systems. Now researchers from the Max Planck Institute for Ornithology in Seewiesen, Germany, and Queen's University Belfast have discovered with colleagues from Israel that a night active mammal, the greater mouse-eared bat, has the capability to orient using polarized light.
A new home-grown instrument based on bundles of optical fibres is giving Australian astronomers the first 'Google street view' of the cosmos — incredibly detailed views of huge numbers of galaxies.
Developed by researchers at the University of Sydney and the Australian Astronomical Observatory, the optical-fibre bundles can sample the light from up to 60 parts of a galaxy, for a dozen galaxies at a time.
This beautiful star cluster, NGC 3293, is found 8000 light-years from Earth in the constellation of Carina (The Keel). This cluster was first spotted by the French astronomer Nicolas-Louis de Lacaille in 1751, during his stay in what is now South Africa, using a tiny telescope with an aperture of just 12 millimetres. It is one of the brightest clusters in the southern sky and can be easily seen with the naked eye on a dark clear night.
"Astronomers have long suspected millisecond pulsars were spun up through the transfer and accumulation of matter from their companion stars, so we often refer to them as recycled pulsars," explained Anne Archibald, a postdoctoral researcher at the Netherlands Institute for Radio Astronomy (ASTRON) in Dwingeloo who discovered J1023 in 2007.
The Carlton Complex fires started on July 14, 2014, by lightning from a weather system that moved through the Methow Valley. The Carlton Complex consists of four fires: Stokes Fire, Gold Hikes Fire, French Creek Fire and the Cougar Flat. The Stokes and Gold Hikes fires are now one larger fire. The fires are burning in timber and grass and the area burning is currently over 243,000 acres in size. The present fire situation continues to rapidly change due to the high fire danger. Public and firefighter safety is the priority on the Carlton Complex fires.
Two instruments aboard NASA's Aqua satellite provided different views of Typhoon Matmo on its approach to Taiwan today, July 22.
NASA's TRMM satellite measured up Super Typhoon Rammasun's rainfall rates, rainfall totals and cloud heights providing a look at the inner workings and aftermath of the storm.
Super Typhoon Rammasun struck the southern coast of China on Friday, July 18 as a very powerful super typhoon with sustained winds estimated at 135 knots (~155 mph or equivalent to a Category 5 hurricane on the US Saffir-Simpson scale), making it the strongest typhoon to hit the area in several decades.
Infrared data gathered on the tropical low pressure area known as System 92L gave forecasters a hint that the low would become the Atlantic Ocean hurricane season's second tropical depression.
Scientists have discovered that greater mouse-eared bats use polarisation patterns in the sky to navigate – the first mammal that's known to do this.
The bats use the way the Sun's light is scattered in the atmosphere at sunset to calibrate their internal magnetic compass, which helps them to fly in the right direction, a study published in Nature Communications has shown.
Despite this breakthrough, researchers have no idea how they manage to detect polarised light.
Environment Canada has issued a high health risk warning for Yellowknife and surrounding area because of heavy smoke in the region due to forest fires. Currently 160 wildfires are burning across the region. There are no plans for evacuation since these fires are endangering people or property. Weather that has been hitting the area recently comes with mixed results. The rains help to dampen the fires, but the lightning tends to start others.
Astronomers using the NASA/ESA Hubble Space Telescope have probed the extreme outskirts of the stunning elliptical galaxy Centaurus A. The galaxy's halo of stars has been found to extend much further from the galaxy's centre than expected and the stars within this halo seem to be surprisingly rich in heavy elements. This is the most remote portion of an elliptical galaxy ever to have been explored.
It's human nature to hate losing.
Unfortunately, it's also human nature to overreact to a loss, potentially abandoning a solid strategy and thus increasing your chances of losing the next time around.
That's one conclusion of a Brigham Young University study published this week by the journal Management Science. The finding is based on an analysis of two decades of data on NBA coaching decisions.
