Global warming predictions are overestimated, suggests study on black carbon
A detailed analysis of black carbon -- the residue of burned organic matter -- in computer climate models suggests that those models may be overestimating global warming predictions. view more (2008-11-20)
Conductive plastics made from natural, renewable, environmentally friendly soybeans
Polymer matrix composites with carbon black are very interesting materials. This is because the carbon black can be used as filler material and can beneficially modify the electrical and mechanical properties of the used matrixes. view more (2007-05-30)
Stellar explosion displays massive carbon footprint
While humans are still struggling to get rid of unwanted carbon it appears that the heavens are really rather good at it. view more (2009-06-01)
Coal and black liquor can produce energy from papermaking
Adding a little coal and processing the papermaking industry's black liquor waste into synthesis gas is a better choice than burning it for heat, improves the carbon footprint of coal-to-liquid processes, and can produce a fuel versatile enough to run a cooking stove or a truck, according to a team of Penn state engineers. view more (2007-08-21)
Study Finds Plenty of Carbon Dioxide Storage Capacity Underground in Kentucky
As concern has grown over the effects of the human release of carbon dioxide (CO2) gas into the atmosphere, so too has research into technologies to manage CO2. view more (2006-10-09)
Improved air quality during Beijing Olympics could inform pollution-curbing policies
The air in Beijing during the 2008 Olympics was cleaner than the previous year's, due to aggressive efforts by the Chinese government to curtail traffic, increase emissions standards and halt construction in preparation for the games, according to a Cornell study. view more (2009-07-27)
Black carbon pollution emerges as major player in global warming
Black carbon, a form of particulate air pollution most often produced from biomass burning, cooking with solid fuels and diesel exhaust, has a warming effect in the atmosphere three to four times greater than prevailing estimates, according to scientists in an upcoming review article in the journal Nature Geoscience. view more (2008-03-24)
Bugs expose underground carbon traffic system 10 times more important than fossil fuel burning
The flow of carbon through soil is ten times greater than the amount of carbon moved around by the burning of fossil fuel but until now how this happens was at best poorly understood. view more (2005-10-10)
From trees to high-performance ceramics
When a racing driver brakes, the discs and linings become red-hot. These parts are commonly made of carbon-fiber-reinforced carbon and are black at moderate temperatures. Car manufacturers and their suppliers would dearly like to extend the use of these special brake pads and other hard-wearing parts developed for racing vehicles to perfectly... view more...

Does racial stereotyping still occur in psychiatry?
Ten years ago, psychiatrists rated black male patients as potentially more violent than white patients. A study in this week's BMJ asks does such racial stereotyping still occur? A postal questionnaire, concerning the first presentation of a young man at casualty, was sent to 1000 British psychiatrists. It included a photograph, brief history, and... view more... (2001-10-17)
Transported Black Carbon a Significant Player in Pacific Ocean Climate
Soot and other particulate pollution from Asian sources make up more than 75 percent of black carbon transported at high altitudes, according to a Scripps Institution of Oceanography, UC San Diego-led study. view more (2007-03-15)
Ethnicity important factor in rates of gonorrhoea and chlamydia infections
Rates of gonorrhoea and chlamydia are about three times as high in black Caribbeans as they are in black Africans, shows a study in Sexually Transmitted Infections. Cases of gonorrhoea and chlamydia, recorded at 11 sexual health clinics in Lambeth, Southwark, and Lewisham Health Authority for the years 1994 and 1995, were studied. Ethnic group was... view more... (2001-02-02)
Increased atmospheric carbon dioxide promotes algal growth
It is usually thought that unlike terrestrial plants, submerged plants like algae will not show any response to an increase of atmospheric carbon dioxide. This view may be biased by a neglect of the effects of the plants themselves on the water chemistry. In the June issue of Ecology Letters, Schippers, Lürling and Scheffer of the Wageningen... view more... (2004-05-13)
Biggest 'small' black hole discovered
Discovery of the largest example of a "small" black hole - one formed from the collapse of a single massive star at the end of its lifetime - has led scientists to revaluate of how black holes come into being, according to a report in Nature. view more (2007-10-22)
Black pudding may interfere with cancer screening test
Eating black pudding may interfere with a screening test for colorectal cancer, claim researchers in this week’s Christmas issue of the BMJ. view more (2002-12-18)
Man-made soot contributed to warming in Greenland in the early 20th century
New research shows that industrial development in North America between 1850 and 1950 greatly increased the amount of black carbon--commonly known as soot-- that fell on Greenland's glaciers and ice sheets. view more (2007-08-10)

UCLA physicists create world's smallest incandescent lamp
In an effort to explore the boundary between thermodynamics and quantum mechanics - two fundamental yet seemingly incompatible theories of physics - a team from the UCLA Department of Physics and Astronomy has created the world's smallest incandescent lamp. view more (2009-05-07)
Cookie cutter in the sky
Black holes can now be thought of as donut holes. The shape of material around black holes has been seen for the first time: an analysis of over 200 active galactic nuclei-cores of galaxies powered by disks of hot material feeding a super-massive black hole-shows that all have a consistent, ordered physical structure that seems to be independent... view more...

The Last Cry Of Matter
'Black holes' are truly black. When an object gets within a certain distance from a black hole, it will get swallowed forever with no chance to escape. That includes light, which means that black holes do not shine. How do astronomers detect black holes if they are unable to see them? Well, to be precise, astronomers do not detect black holes.... view more... (2003-11-27)
