Green light from FDA for CT lung-imaging software Posted: 02 Dec 2014 01:13 PM PST New technology may soon help lung disease patients around the world breathe a little easier, by helping their doctors make a clearer diagnosis and more individualized treatment plan.

Lengthening life of high capacity silicon electrodes in rechargeable lithium batteries with novel rubber-like coating Posted: 02 Dec 2014 11:49 AM PST A new study will help researchers create longer-lasting, higher-capacity lithium rechargeable batteries, which are commonly used in consumer electronics. Researchers have shown how a coating that makes high capacity silicon electrodes more durable could lead to a replacement for lower-capacity graphite electrodes.

How to stop the spread of HIV in Africa Posted: 02 Dec 2014 11:47 AM PST To stop the spread of HIV in Africa, researchers, using a complex mathematical model, have developed a strategy that focuses on targeting "hot zones," areas where the risk of HIV infection is much higher than the national average.

Atmospheric carbon dioxide used for energy storage products Posted: 02 Dec 2014 11:06 AM PST Researchers have discovered a fascinating new way to take some of the atmospheric carbon dioxide that's causing the greenhouse effect and use it to make an advanced, high-value material for use in energy storage products.

A better look at the chemistry of interfaces Posted: 02 Dec 2014 10:54 AM PST SWAPPS - Standing Wave Ambient Pressure Photoelectron Spectroscopy – is a new X-ray technique that provides sub-nanometer resolution of every chemical element to be found at heterogeneous interfaces, such as those in batteries, fuel cells and other devices.

Missing ingredient in energy-efficient buildings: Trained people Posted: 02 Dec 2014 10:24 AM PST More than one-third of new commercial building space includes energy-saving features, but without training or an operator's manual many occupants are in the dark about how to use them.

Losing air: Barrage of small impacts likely erased much of the Earth’s primordial atmosphere Posted: 02 Dec 2014 10:23 AM PST Researchers believe a blitz of small space rocks, or planetesimals, may have bombarded Earth around the time the moon was formed, kicking up clouds of gas with enough force to permanently eject small portions of the atmosphere into space.

Strange galaxy perplexes astronomers: Prominent 'jets' of subatomic particles Posted: 02 Dec 2014 10:23 AM PST With the help of citizen scientists, astronomers have found an important new example of a very rare type of galaxy that may provide valuable insight on galaxy evolution in the early Universe.

Inexpensive hydrolysable polymer developed Posted: 02 Dec 2014 09:38 AM PST Through some inventive chemistry, scientists have developed a class of 'hindered urea bond-containing polymeric materials' or 'poly(hindered urea)s' -- cheap polymers that can be designed to degrade over a specified time period, making them potentially useful in biomedical and agricultural applications.

Nanotubes may restore sight to blind retinas Posted: 02 Dec 2014 09:38 AM PST Retinal degeneration is one of the most worrisome dangers in the aging process. Now researchers have made an important technological breakthrough towards a prosthetic retina that could help alleviate conditions that result from problems with this vital part of the eye.

See it, touch it, feel it: Researchers use ultrasound to make invisible 3-D haptic shape that can be seen and felt Posted: 02 Dec 2014 09:38 AM PST Technology has changed rapidly over the last few years with touch feedback, known as haptics, being used in entertainment, rehabilitation and even surgical training. New research, using ultrasound, has developed an invisible 3-D haptic shape that can be seen and felt.

Traces of Martian biological activity could be locked inside a meteorite Posted: 02 Dec 2014 09:01 AM PST Did Mars ever have life? Does it still? A meteorite from Mars has reignited the old debate. New research shows that Martian life is more probable than previously thought.

Chemists fabricate novel rewritable paper Posted: 02 Dec 2014 09:01 AM PST Chemists have fabricated novel rewritable paper, one that is based on the color switching property of commercial chemicals called redox dyes. The dye forms the imaging layer of the paper. Printing is achieved by using ultraviolet light to photobleach the dye, except the portions that constitute the text on the paper. The new rewritable paper can be erased and written on more than 20 times with no significant loss in contrast and resolution.

Fighting air pollution in China with social media Posted: 02 Dec 2014 09:00 AM PST The serious air pollution problem in China has attracted the attention of online activists who want the government to take action, but their advocacy has had only limited success, a new study has revealed.

First study of 'Golden Age' mandolins unlocks secrets of their beauty Posted: 02 Dec 2014 07:34 AM PST Analyzing varnishes and decorations could provide a new way to identify mandolin "Old Masters." Some of the most elaborately decorated instruments in history were produced in 18th century Naples. The materials for varnishes and decorations used by individual mandolin masters, honed for wealthy clients in the ancient city's labyrinthine artisan quarter, have been kept secret for over 200 years.

3-D mammography improves cancer detection in dense breasts Posted: 02 Dec 2014 05:24 AM PST A major new study has found that digital breast tomosynthesis, also known as 3-D mammography, has the potential to significantly increase the cancer detection rate in mammography screening of women with dense breasts.

Meteorology meets metrology: Climate research high up in the clouds Posted: 02 Dec 2014 05:23 AM PST Barely has the research aircraft HALO entered the kilometer-high clouds towering above the Brazilian rainforest than the researchers find themselves in a complete haze, but they can rely on the measuring instruments that are working at full capacity. HAI – a new, highly accurate hygrometer – is aboard. The shooting star among hygrometers has been developed only recently by metrologists (metrology = the science of measurement) especially for use on board aircraft and in the clouds, but it has already been used in four research campaigns and has already clocked up more than 300 hours of active use. It is the only device worldwide that can determine precisely and simultaneously how much of the water present in the atmosphere is in the form of vapour, condensation, droplets or ice.

NASA's CATS eyes clouds, smoke and dust from the space station Posted: 01 Dec 2014 04:14 PM PST To investigate the layers and composition of clouds and tiny airborne particles like dust, smoke and other atmospheric aerosols, , scientists have developed an instrument called the Cloud-Aerosol Transport System, or CATS.

Sweet smell of success: Researchers boost methyl ketone production in e. coli Posted: 01 Dec 2014 01:35 PM PST Researchers have engineered E. coli bacteria to convert glucose into significant quantities of methyl ketones, a class of chemical compounds primarily used for fragrances and flavors, but highly promising as clean, green and renewable blending agents for diesel fuel.

Saving energy with nanotechnology insulation Posted: 01 Dec 2014 01:30 PM PST Filling vacuum insulation panels with new, low-cost materials could produce hundreds of millions of dollars in energy savings, experts say.

2D images as new tool for cancer prevention Posted: 30 Nov 2014 06:38 PM PST A new method, which from images of a protein in a population of cells quantifies its distribution for that population, has been revealed by researchers. The discovery has important medical implications since the cellular location of a protein is directly linked to its function.

A numbers game: Math helps to predict how the body fights disease Posted: 27 Nov 2014 06:23 PM PST Walter and Eliza Hall Institute researchers have defined for the first time how the size of the immune response is controlled, using mathematical models to predict how powerfully immune cells respond to infection and disease.
