The GOES-13 satellite is watching Tropical Storm Richard work its way through the western Caribbean, and residents of eastern Honduras, Guatemala, Belize and Mexico's Yucatan Peninsula are bracing for its impacts as it is forecast to strengthen to hurricane status this weekend. Richard is going to be a big rainmaker for those countries.
Rice University has created a Green Carbon Center to bring the benefits offered by oil, gas, coal, wind, solar, geothermal, biomass and other energy sources together in a way that will not only help ensure the world's energy future but also provide a means to recycle carbon dioxide into useful products.
The annual "Euromelanoma Day" campaign is designed to prevent skin cancer among the general public. While there has been considerable interest, it has proved difficult to reach out to some of the at-risk groups. As such, new ways of encouraging these people to go to a dermatologist are being introduced, reveals research from the University of Gothenburg presented at the dermatologist conference in Sweden.
John Paoli is a researcher at the Sahlgrenska Academy and specialist at Sahlgrenska University Hospital's dermatology clinic, and one of the speakers at the conference.
URBANA – A University of Illinois study has shown for the first time that sulforaphane, the powerful cancer-fighting agent in broccoli, can be released from its parent compound by bacteria in the lower gut and absorbed into the body.
"This discovery raises the possibility that we will be able to enhance the activity of these bacteria in the colon, increasing broccoli's cancer-preventive power," said Elizabeth Jeffery, a U of I professor of human nutrition.

CAMBRIDGE, Mass. -- Most marathon runners know they need to consume carbohydrates before and during a race, but many don't have a good fueling strategy. Now, one dedicated marathoner -- an MD/PhD student in the Harvard-MIT Division of Health Sciences and Technology -- has taken a more rigorous approach to calculating just how much carbohydrate a runner needs to fuel him or herself through 26.2 miles, and what pace that runner can reasonably expect to sustain.
At the heart of the method is a so-called quantum point contact (QPC). This is a narrow conductive channel in a semiconductor circuit. The scientists created a 70-nanometer narrow channel, about as wide as the wavelength of electrons in the semiconductor. The key is that only one electron at a time will fit through the channel, making possible extremely high-precision measurements of the electric current. As described in the current publication, this method was applied to photogenerated electrons for the first time ever.
WASHINGTON, Oct. 21 – A team of scientists at Alcatel-Lucent Bell Labs have examined the energy consumption trends of communications equipment in use today and determined that gains in energy efficiency are not keeping pace with traffic growth. One consequence is that energy is going to become an increasingly important problem for communication networks.
Researchers found that the combination of computed tomography (CT), postmortem CT angiography (CTA) and biopsy can serve as a minimally invasive option for determining natural causes of death such as cardiac arrest, according to a study in the November issue of the American Journal of Roentgenology.
In the last decade, postmortem imaging, especially CT, has gained increasing acceptance in the forensic field. However, CT has certain limitations in the assessment of natural death.
RIVERSIDE, Calif. – Does the environment encountered early in life have permanent and predictable long-term effects in adulthood? Such effects have been reported in numerous organisms, including humans.
DURHAM, N.C. -- Being the right size and existing in the limbo between a solid and a liquid state appear to be the secrets to improving the efficiency of chemical catalysts that can create better nanoparticles or more efficient energy sources.
DURHAM, N.C. -- Step aside copper and make way for a better carrier of information -- light.
