Breathing easy while sleeping could combat symptoms of altitude sickness

By - April 14, 2014 1 Picture
Headaches, nausea, weakness and dizziness, combined with a feeling that you just can’t get enough oxygen with each breath are just some of the signs of altitude sickness. Researchers have now found a link between the abnormal breathing patterns experienced while sleeping at altitude and the symptoms of altitude sickness, particularly headaches. The finding suggests that finding a way to breath normally while sleeping could provide a way to combat such symptoms. Read More

New Bosch system shuts off coasting cars' engines

By - January 8, 2014 1 Picture
Cars don't need to have their engines running when they're stopped at red lights. That's why a number of automakers have developed start-stop systems, which stop a car's engine when the vehicle comes to a halt, and start it again as soon as the gas pedal is pressed. Bosch, however, is taking things farther. Its new start-stop system shuts the engine off not only at stops, but also whenever the car is coasting. Read More

Smart door seal keeps conference rooms from getting stuffy

If you’re in a confidential meeting with the boardroom door closed, the air can get stale pretty fast. Should it be too cold outside to crack any windows, or if the room simply has no windows, then opening those isn’t a choice. That’s why Germany’s Fraunhofer Institute for Microelectronic Circuits and Systems has teamed up with the Athmer Company to create an “intelligent door seal system.” Read More

Simpler, cheaper way to make liquid methanol fuel using CO2 and sunlight

Most previous methods of producing methanol from carbon dioxide have involved lots of electricity, high pressures and high temperatures, and used toxic chemicals or rare earth elements like cadmium or tellurium. A team of researchers at the University of Texas at Arlington (UTA) has developed a new method they claim is safer, less expensive, and simpler than current approaches and can be scaled up to an industrial scale to allow some of the CO2 emitted from electrical power plants to be captured and converted into a useful fuel.

Genetically modified microorganism could convert atmospheric CO2 into fuel

By - March 29, 2013 1 Picture
While much research is being done on capturing carbon dioxide emissions at their source to reduce the amount expelled into the atmosphere, researchers at the University of Georgia’s Bioenergy Systems Research Institute have taken a different approach to tackle the problem. Taking a leaf out of the process used by plants to convert CO2 into something useful, they have uncovered a way to take CO2 from the atmosphere and transform it into useful industrial products, including, potentially, fuel.

Researchers develop more energy efficient carbon capture material

By - March 11, 2013 1 Picture
Carbon capture is one of the many solutions proposed to curb emissions of CO2. But, so far, methods being used require a great deal of energy to release the captured carbon from the capture material for storage. Now researchers at the University of South Florida (USF), in a partnership with King Abdullah University of Science and Technology (KAUST), have announced what they claim is a more energy-efficient alternative in the shape of a cheaper, more efficient and reusable material for CO2 capture and separation.

Carbon-capture material releases trapped CO2 when exposed to sunlight

By - February 13, 2013 1 Picture
Amidst concerns over the accumulation of atmospheric greenhouse gases, many research institutes have been looking into methods of carbon sequestration – the capture, storage and even possible reuse of carbon dioxide emissions. Unfortunately, some of the approaches require a considerable input of power, in order to release the captured CO2. A new material developed at Australia’s Monash University, however, requires nothing but sunlight. Read More

Sea urchins reveal promising carbon capture alternative

By - February 4, 2013 1 Picture
Carbon capture and sequestration in underground reservoirs isn’t the most practical or cost effective way to reduce atmospheric CO2 levels. It would be much simpler if CO2 could be quickly and cheaply converted into a harmless, solid mineral before it is released into the atmosphere. A team from the U.K.’s Newcastle University may have stumbled across a way to achieve this thanks to the humble sea urchin. Read More
