Astronomers suggest new telescopes could detect biomarker gasses in exoplanet atmospheres
New method of measuring the mass of supermassive black holes
(Phys.org)—A new way of measuring the mass of supermassive black holes could revolutionise our understanding of how they form and help to shape galaxies.
OSHA: Sandy contamination below permissible limits
(AP)—Tests done at Superstorm Sandy cleanup sites show that the level of contaminants does not exceed federal workplace exposure limits.
Wood-burning sets off pollution alarm bells in Athens
Air pollution in Athens has surged in recent days because of people choosing wood over more expensive fuels to heat their homes in the grips of a continuing economic crisis, the environment ministry said ...
Variable congestion charges may yield more stable air quality and improved health
Higher congestion charges in the morning and in the spring would even out the negative health effects caused by air pollution from cars in large cities.
First satellite detection of volcanogenic carbon monoxide
Measuring and tracking the gases that vent from an erupting volcano is a project wrought with potential dangers and difficulties. On the ground measurements place researchers in harm's way, as do airborne sampling surveys. ...
Astronomers discover and 'weigh' youngest still-forming planetary system yet found
Astronomers have found the youngest still-forming solar system yet seen, an infant star surrounded by a swirling disk of dust and gas more than 450 light-years from Earth in the constellation Taurus.
Even brown dwarfs may grow rocky planets
(Phys.org)—Astronomers using the Atacama Large Millimeter/submillimeter Array have for the first time found that the outer region of a dusty disc encircling a brown dwarf contains millimetre-sized solid ...
Researchers stretch C-O bond to record length
Comet collisions every six seconds explain 17-year-old stellar mystery
(Phys.org)—Every six seconds, for millions of years, comets have been colliding with one another near a star in the constellation Cetus called 49 CETI, which is visible to the naked eye.
In world's first, atomic force microscope sees chemical bonds in individual molecules (w/ video)
(Phys.org)—IBM scientists have been able to differentiate the chemical bonds in individual molecules for the first time using a technique known as noncontact atomic force microscopy (AFM).
Wetlands the primary source of Amazon Basin methane
The Amazon basin is an important sink of carbon dioxide, but it is also a substantial source of atmospheric methane. Tropical wetlands, including those in the Amazon, are one of the largest sources of biogenic methane and ...
The latest advance in imaging technology helps optimize catalysts for use in onboard fuel processing
The presence of carbon monoxide (CO) impurities in hydrogen gas (H2) can have a detrimental impact on the performance of fuel cells. Recent studies have shown that gold nanoparticles—particles less than ...
Scientists' gold discovery sheds light on catalysis
(Phys.org) -- A physicist at the University of York has played a key role in international research which has made an important advance in establishing the catalytic properties of gold at a nano level.
