Big power from tiny wires: Carbon nanotubes can produce powerful waves that could be harnessed for new energy systems
|
Scientists have discovered a previously unknown phenomenon that can cause powerful waves of energy to shoot through minuscule wires known as carbon nanotubes. The discovery could lead to a new way of producing electricity, the researchers say.

Low oxygen levels in body linked to cancer-aiding protein
|
A professor of biochemistry who was researching protein kinase C gamma in the lens of the human eye found her work taking a fascinating turn when she discovered a correlation between the protein Coonexin46 and hypoxia -- a deficiency of oxygen which kills normal tissue cells. The researcher believes the findings will lead to serious advancements in treating retinoblastoma, a cancer that forms in the tissue of the retina.

Ever-changing Earth: How the atmosphere can affect planet's shape, rotation, gravitational field
|
Researchers in Austria are investigating the effects of the Earth's atmosphere on our planet's shape, its rotation and its gravitational field. The researchers' aim is to develop a better understanding of the Earth's system and to support the development of the Global Geodetic Observing System (GGOS).

Cotton is the fabric of your lights, your MP3 player, your cell phone
|
Consider this T-shirt: It can monitor your heart rate and breathing, analyze your sweat and even cool you off on a hot summer's day. Or a solar-powered dress that can charge your MP3 player? This is not science fiction -- this is cotton in 2010.

Life is shorter for men, but sexually active life expectancy is longer
|
At age 55, men can expect another 15 years of sexual activity, but women that age should expect less than 11 years, according to a new study. Men in good or excellent health at 55 can add 5 to 7 years to that number. Equally healthy women gain slightly less, 3 to 6 years.

Scientists discover 'catastrophic event' behind the halt of star birth in early galaxy formation
|
Scientists have found evidence of a catastrophic event they believe was responsible for halting the birth of stars in a galaxy in the early universe. The researchers observed the massive galaxy as it would have appeared just three billion years after the Big Bang when the Universe was a quarter of its present age.

New study questions benefits of elective removal of ovaries during hysterectomy
|
Removal of the ovaries (bilateral oophorectomy) while performing a hysterectomy is common practice to prevent the subsequent development of ovarian cancer. This prophylactic procedure is performed in 55% of all U.S. women having a hysterectomy, or approximately 300,000 times each year. A new article suggests that this procedure may do more harm than good.

Chemical competition: Research identifies new mechanism regulating embryonic development
|
A research team has discovered that protein competition over an important enzyme provides a mechanism to integrate different signals that direct early embryonic development. The work suggests that these signals are combined long before they interact with the organism's DNA, as was previously believed, and also may inform new therapeutic strategies to fight cancer.

Hemoglobin A1c outperforms fasting glucose for risk prediction
|
Measurements of hemoglobin A1c (HbA1c) more accurately identify persons at risk for clinical outcomes than the commonly used measurement of fasting glucose, according to a new study. HbA1c levels accurately predict future diabetes, and they better predict stroke, heart disease and all-cause mortality as well.

Future of broadband: Where data is broadcast using desk lamps
|
In the future, getting a broadband connection might be as simple as flipping on a light switch. In fact, according to a group of researchers from Germany, the light coming from the lamps in your home could one day encode a wireless broadband signal.

Acts of kindness spread surprisingly easily: just a few people can make a difference
|
For all those dismayed by scenes of looting in disaster-struck zones, whether Haiti or Chile or elsewhere, take heart: good acts -- acts of kindness, generosity and cooperation -- spread just as easily as bad. And it takes only a handful of individuals to really make a difference.

Lizard moms choose the right genes for the right gender offspring
|
Brown anole lizards make an interesting choice when deciding which males should father their offspring. The females of this species mate with several males, then produce more sons with sperm from large fathers, and more daughters with sperm from smaller fathers. The researchers believe that the lizards do this to ensure that the genes from large fathers are passed on to sons, who stand to benefit from inheriting the genes for large size.

'The Rosenfeld' named after California's godfather of energy efficiency
|
Pioneering French physicists Marie and Pierre Curie have the curie, a unit of radioactivity, named after them. Renowned inventor Nikola Tesla is honored with the tesla, which measures a magnetic field. And now, the Rosenfeld, proposed as a unit for electricity savings, will be named after the man seen by many people as the godfather of energy efficiency, Arthur Rosenfeld.
