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.
DASH eating plan lowers long-term heart attack risk, especially among African-Americans
The DASH eating plan, known to reduce blood pressure and bad cholesterol, also reduces the 10-year risk of heart attack, especially among African-Americans, according to research reported in Circulation: Cardiovascular Quality and Outcomes, an American Heart Association journal.
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.
Free as a bird? Researchers find that man-made development affects bird flight patterns and populations
It may seem like birds have the freedom to fly wherever they like, but researchers at the University of Missouri have shown that what's on the ground has a great effect on where a bird flies. This information could be used by foresters and urban planners to improve bird habitats that would help maintain strong bird populations.
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...
High-fat diet during puberty linked to breast cancer risk later in life
Girls eating a high-fat diet during puberty, even those who do not become overweight or obese, may be at a greater risk of developing breast cancer later in life, according to Michigan State University researchers.
Home-based intervention may provide some benefit to patients with dementia and their caregivers
An intervention that targeted modifiable stressors in the home of patients with dementia resulted in better outcomes for the patients and their caregivers at 4 months, but not at 9 months, although the caregivers perceived greater benefits, according to a study in the September 1 issue of JAMA.
Hooked on Headphones? Personal Listening Devices Can Harm Hearing
Personal listening devices like iPods have become increasingly popular among young - and not-so-young - people in recent years. But music played through headphones too loud or too long might pose a significant risk to hearing, according to a 24-year study of adolescent girls.
Hourly workforce carries burden during recession
The United States workforce, battered by an economic slowdown, now includes a record number of workers who are involuntarily working part-time due to reduced hours or the inability to find a full-time job.
NASA's Terra Satellite captures 3 tropical cyclones in the northwestern Pacific Ocean
NASA's Terra satellite flew over the Northwestern Pacific Ocean at 10:30 p.m. EDT Aug. 30 and captured Tropical Storm Lionrock, Tropical Storm Namtheun, and Typhoon Kompasu in one incredible image. Two of these tropical cyclones are expected to merge, while the other is headed for a landfall in China.
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.
Prophylactic surgeries associated with lower risk of cancer for women with BRCA1/2 gene mutations
Women at increased risk of breast and ovarian cancer because of inherited mutations of the BRCA1 or BRCA2 genes who had prophylactic mastectomy or salpingo-oophorectomy (removal of the fallopian tubes and ovaries) had an associated decreased risk of breast cancer and ovarian cancer, according to a study in the September 1 issue of JAMA.
Species cooperate out of self-interest rather than to be mutually beneficial, study says
(PhysOrg.com) -- Applying employment contract theory to symbiosis, a new paper suggests that the mutually beneficial relationships that species create are maintained because of simple self-interest, with partners benefiting from healthy hosts, much as employees benefit from robust employers.
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.
Stem cell ruling puts researcher's project in limbo
(PhysOrg.com) -- Promising work by Joanna Wysocka, PhD, has been thrown into an uncertain limbo by a recent injunction suspending federal funding for human embryonic stem cell research.
Students create web site to track historic twitter trends

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.
