Canon develops world's largest CMOS image sensor, with ultra-high sensitivity

Canon Inc. announced today that it has developed the world's largest CMOS image sensor, with a chip size measuring 202 x 205 mm. Because its expanded size enables greater light-gathering capability, the sensor is capable of capturing images in one one-hundredth the amount of light required by a professional-model digital SLR camera.

Developments in nanobiotechnology point to medical applications

Two new groundbreaking scientific papers by researchers at UC Santa Barbara demonstrate the synthesis of nanosize biological particles with the potential to fight cancer and other illnesses. The studies introduce new approaches that are considered "green" nanobiotechnology because they use no artificial compounds.

Epson launches volume production of world's first reflective HTPS panels

Seiko Epson today announced that it has developed and begun volume production of the world's first reflective high-temperature polysilicon (reflective HTPS) TFT liquid crystal panels for 3LCD projectors. The new panels, which measure 0.74 inches on the diagonal, support full high-definition (1920 x 1080 pixels) content.

GOES-13 catches 3 tropical cyclones thrashing through the Atlantic

Powerful Hurricane Earl, growing Tropical Storm Fiona and fading Danielle were all captured in today's visible image from the GOES-13 satellite. The Geostationary Operational Environmental Satellite called GOES-13 captured an image of the busy Atlantic Ocean at 1145 UTC (7:45 a.m. EDT) on August 31. In the visible image, was the large and powerful Hurricane Earl passing Puerto Rico, Tropical Storm...

Off-the-shelf dyes improve solar cells

Like most technologies, work on solar devices has proceeded in generational waves. First came bulk silicon-based solar cells built with techniques that borrowed heavily from those used to make computer chips. Next came work on thin films of materials specifically tailored to harvest the sun's energy, but still more or less borrowed from the realm of microelectronics manufacturing. Then came the...

Phenomenon of plate tectonics explained

Transform faults subdivide the mid-ocean ridge into segments. Up until now, it was thought that these faults were ruptures that formed in less stable crust areas. Taras Gerya has recorded a model of the dynamics that lead to the transform faults, which shows that what were assumed to be ruptures are in fact structures that have grown naturally.

Preventive cancer surgeries save women's lives

A new study underscores the importance for women with a family history of breast or ovarian cancer to get genetic counseling and testing for the BRCA1 and BRCA2 genes that make them more likely to develop lethal breast or ovarian cancer, says a Northwestern Medicine oncologist.

Staples to sell Amazon's Kindle

Staples will begin selling Amazon's Kindle electronic book reader this year, making the US office supply chain the second brick-and-mortar store to offer the device.

Study discovers why females fare better than males after traumatic injury

A study published in the September 2010 issue of SHOCK by Dr. Ed W. Childs and colleagues at Scott & White Healthcare looks at how female versus male rats fared after suffering a trauma and subsequent hemorrhagic shock who were given Estradiol (estrogen). In the study, the Estradiol prevented vascular permeability following hemorrhagic shock.

Thinnest eggs belonged to largest Moas

(PhysOrg.com) -- In a detailed online study published by the Proceedings of the National Academy of Sciences on August 30th, scientists investigate questions surrounding New Zealand's moa eggs and the results are mystifying.

FDA looks to curb abuse of cough medicine

(AP) -- Federal health regulators are weighing restrictions on Robitussin, NyQuil and other cough suppressants to curb cases of abuse that send thousands of people to the hospital each year.
