• 06:10 Social Background Weighs Heavily On Teenage Diet

  Read the story at ScienceDaily
  Teenagers' attitudes to diet and weight are shaped by their social class, according to new research. Policymakers have long insisted on the importance of understanding young people's health and eating habits but this is the first study to show how everyday practices and perceptions of different social classes contribute to variation in the diet, weight and health of teenagers.

• 06:10 'Green' Roofs Could Help Put Lid On Global Warming

  Read the story at ScienceDaily
  "Green" roofs, those increasingly popular urban rooftops covered with plants, could help fight global warming, scientists in Michigan are reporting. Their study is the first of its kind to examine the ability of green roofs to sequester carbon which may impact climate change.

• 06:10 Enzyme Is Key To Clogged Arteries, Scientists Find

  Read the story at ScienceDaily
  Scientists have made an important discovery in understanding what causes arteries to clog up. They have discovered that an enzyme called matrix metalloproteinase-8 plays a crucial role in raising blood pressure and causing abnormal build-up of cells in the arteries -- both of which increase the risk of heart disease. The scientists say that their research could lead to new drugs for treating high blood pressure and preventing heart disease.

• 06:10 Fish Fend Off Invading Germs With An Initial Response Similar To One Found In Humans

  Read the story at ScienceDaily
  A new study demonstrates that the same proteins produced by humans early during infection are also made by fish early after exposure to harmful germs. These proteins activate the fish immune system in a process that resembles that in humans. But unlike humans, the inflammatory response in young zebrafish is simple, making it easier to tease out the pathways involved in the fight against infection.

• 06:10 Detailed Glimpse Of Chemoreceptor Architecture In Bacterial Cells

  Read the story at ScienceDaily
  Using state-of-the-art electron microscopy techniques, researchers have for the first time visualized and described the precise arrangement of chemoreceptors -- the receptors that sense and respond to chemical stimuli -- in bacteria. In addition, they have found that this specific architecture is the same throughout a wide variety of bacterial species, which means that this is a stable, universal structure that has been conserved over evolutionary time.

• 06:10 Toad Venom In Cancer Treatment: Traditional Chinese Medicine Is Well-tolerated, Study Shows

  Read the story at ScienceDaily
  Huachansu, a Chinese medicine that comes from the dried venom secreted by the skin glands of toads, has tolerable toxicity levels, even at doses eight times those normally administered, and may slow disease progression in some cancer patients, say US researchers.

• 06:10 Ultrasound Can Predict Tumor Burden And Survival In Melanoma Patients

  Read the story at ScienceDaily
  Researchers have shown for the first time that patterns of ultrasound signals can be used to identify whether or not cancer has started to spread in melanoma patients, and to what extent. The discovery enables doctors to decide on how much surgery, if any, is required and to predict the patient's probable survival.

• 06:10 Use Of Statins Favors The Wealthy, Creating New Social Disparities In Cholesterol, Study Finds

  Read the story at ScienceDaily
  Since the introduction of statins to treat high cholesterol, the decline in lipid levels experienced by the wealthy has been double that experienced by the poor. Statin use may have contributed to expanding social disparities in the treatment of cardiovascular disease, according to new research.
