An atomic-level look at an HIV accomplice
Since the discovery in 2007 that a component of human semen called SEVI boosts infectivity of the virus that causes AIDS, researchers have been trying to learn more about SEVI and how it works, in hopes of thwarting its infection-promoting activity.   view more (2009-11-20)

Antifibrotic effects of green tea

Vibrations key to efficiency of green fluorescent protein
University of California, Berkeley, chemists have discovered the secret to the success of a jellyfish protein whose green glow has made it the darling of biologists and the subject of the 2008 Nobel Prize in Physiology or Medicine.   view more (2009-11-12)

Early life on Earth may have developed more quickly than thought
The Earth's climate was far cooler - perhaps more than 50 degrees - billions of years ago, which could mean conditions for life all over the planet were more conducive than previously believed, according to a research team that includes a Texas A&M University expert who specializes in geobiology.   view more (2009-11-12)

Reducing greenhouse gases may not be enough to slow climate change
Because land use changes are responsible for 50 percent of warming in the US, policymakers need to address the influence of global deforestation and urbanization on climate change, in addition to greenhouse gas emissions.   view more (2009-11-11)

Does green tea prevent cancer? Evidence continues to brew, but questions remain
Although scientists are reluctant to officially endorse green tea as a cancer prevention method, evidence continues to grow about its protective effects, including results of a new study published in Cancer Prevention Research, a journal of the American Association for Cancer Research, which suggests some reduction in oral cancer.   view more (2009-11-05)

Green tea shows promise as chemoprevention agent for oral cancer, M. D. Anderson study finds
Green tea extract has shown promise as cancer prevention agent for oral cancer in patients with a pre-malignant condition known as oral leukoplakia, according to researchers at The University of Texas M. D. Anderson Cancer Center.   view more (2009-11-05)

Hoping to keep the flu at bay? A strong immune system helps. Enjoying the bounty of colorful fruits and vegetables available right now can be an important step toward supporting your family's immune system this cold/flu season.   view more (2009-11-04)

Sneezing in times of a flu pandemic
The swine flu (H1N1) pandemic has received extensive media coverage this year. The World Health Organization, in addition to providing frequent updates about cases of infection and death tolls, recommends hyper vigilance in daily hygiene such as frequent hand washing or sneezing into the crook of our arms.   view more (2009-11-03)

NIH-funded researchers transform embryonic stem cells into human germ cells
Researchers funded in part by the National Institutes of Health have discovered how to transform human embryonic stem cells into germ cells, the embryonic cells that ultimately give rise to sperm and eggs.   view more (2009-10-29)

Boston University scientists first to see RNA network in live bacterial cells
Scientists who study RNA have faced a formidable roadblock: trying to examine RNA's movements in a living cell when they can't see the RNA. Now, a new technology has given scientists the first look ever at RNA in a live bacteria cell-a sight that could offer new information about how the molecule moves and works.   view more (2009-10-23)

Penn team uses self-assembly to make molecule-sized particles with patches of charge
Physicists, chemists and engineers at the University of Pennsylvania have demonstrated a novel method for the controlled formation of patchy particles, using charged, self-assembling molecules that may one day serve as drug-delivery vehicles to combat disease and perhaps be used in small batteries that store and release charge.   view more (2009-10-21)

Small mechanical forces have big impact on embryonic stem cells
Applying a small mechanical force to embryonic stem cells could be a new way of coaxing them into a specific direction of differentiation, researchers at the University of Illinois report. Applications for force-directed cell differentiation include therapeutic cloning and regenerative medicine.   view more (2009-10-19)
