• 06:00 Sickle cell study boosts call for improved childhood immunization programs in Africa

  Read the story at EurekAlert
  Children in Africa with sickle cell anemia are dying unnecessarily from bacterial infections, suggests the largest study of its kind, funded by the Wellcome Trust. The results are published today in the journal the Lancet. The study has prompted calls for all children in Africa to receive vaccinations against the most common bacterial infections.

• 06:00 Small businesses would see lower costs, more comprehensive coverage from health reform

  Read the story at EurekAlert
  Small business owners and employees are among those who stand to benefit the most from provisions in some of the current health reform proposals under consideration by Congress according to a Commonwealth Fund report released today. Provisions to extend health care coverage to everyone and repair the small group insurance market would alleviate high premium costs, high broker fees, underwriting, and a lack of transparency about benefit packages that small business owners currently face.

• 06:00 Toward a nanomedicine for brain cancer

  Read the story at EurekAlert
  In an advance toward better treatments for the most serious form of brain cancer, scientists in Illinois are reporting development of the first nanoparticles that seek out and destroy brain cancer cells without damaging nearby healthy cells. The study is scheduled for the Sept. 9 issue of ACS' Nano Letters, a monthly journal.

• 06:00 UAB researchers find TB-prevention therapy is cost-effective option

  Read the story at EurekAlert
  University of Alabama at Birmingham researchers have found that the cost of preventive antibiotic tuberculosis therapy for patients infected by human immunodeficiency virus is generally less expensive than the reported cost of treating newly confirmed TB cases.

• 06:00 University of Arizona researchers seek safer cystic fibrosis test

  Read the story at EurekAlert
  Researchers from the University of Arizona colleges of pharmacy and medicine are teaming up to try to invent a novel noninvasive lung test for cystic fibrosis sufferers. The goal is to find a method that requires a patient only to breath into a machine instead of undergo an invasive procedure.

• 06:00 Virus responsible for deadly brain disease found in MS patients treated with natalizumab

  Read the story at EurekAlert
  The virus responsible for PML (progressive multifocal leukoencephalopathy), a rare brain disease that typically affects AIDS patients and other individuals with compromised immune systems, has been found to be reactivated in multiple-sclerosis patients being treated with natalizumab (Tysabri) according to new research led by scientists at Beth Israel Deaconess Medical Center.

• 06:00 Work conditions impact parents' food choices

  Read the story at EurekAlert
  How working parents cope with competing demands on their time that can compromise food choices for the family and how work conditions are related to food choice coping strategies are the subjects of a study in the September/October issue of the Journal of Nutrition Education and Behavior. Findings suggest that better work conditions may be associated with more positive strategies such as more home-prepared meals, eating with the family, keeping healthful food at work, and less meal skipping.

• 06:00 Yeast unravels effects of chemotherapy drugs

  Read the story at EurekAlert
  Until now, the mode of action of nitrogen-containing bisphosphonate (N-BP) cancer drugs, used to relieve bone pain and to prevent skeletal complications in bone metastasis, has been almost entirely unknown. Researchers writing in BioMed Central's open-access journal Genome Biology have used "barcoded" yeast mutants to identify new biological processes involved in the cellular response to N-BPs, opening up opportunities for the development of new anticancer drugs.

• 06:00 You can believe your eyes: New insights into memory without conscious awareness

  Read the story at EurekAlert
  Scientists may have discovered a way to glean information about stored memories by tracking patterns of eye movements, even when an individual is unable (or perhaps even unwilling) to report what they remember. The research, published by Cell Press in the Sept. 10 issue of the journal Neuron, provides compelling insight into the relationship between activity in the hippocampus, eye movements, and both conscious and unconscious memory.

• 06:00 'Hygiene hypothesis' challenged

  Read the story at EurekAlert
  New research hints that the common belief that kids who go to daycare have lower rates of asthma and allergy later in life might be nothing more than wishful thinking. While young children in daycare definitely do get more illnesses and experience more respiratory symptoms as a result, any perceived protection these exposures afford against asthma and allergy seem to disappear by the time the child hits the age of eight.

• 06:00 'Second hit' pushes noninvasive breast cancer towards deadly metastasis

  Read the story at EurekAlert
  A new study identifies a molecule that acts cooperatively with a well known oncoprotein to drive progression of noninvasive breast cancer to metastatic, life-threatening disease. The research findings, published by Cell Press in the September issue of the journal Cancer Cell, could have a significant impact on therapeutic decisions by facilitating identification of high risk patients.

• 06:00 Arctic oil: A boon for nest predators

  Read the story at EurekAlert
  A new study by the Wildlife Conservation Society, US Fish and Wildlife Service, and other groups reveals how oil development in the Arctic is impacting some bird populations by providing "subsidized housing" to predators, which nest and den around drilling infrastructure and supplement their diets with garbage -- and nesting birds.

• 06:00 Ben-Gurion University of the Negev develops thin films showing promise for solar applications

  Read the story at EurekAlert
  Researchers at Ben-Gurion University of the Negev have developed thin films that exhibit carrier multiplication. This development is of great interest for future solar cells. The BGU team demonstrated that for a given photon energy, carrier multiplication occurs more efficiently in bulk PbS and PbSe films than in nanocrystalline films of the same materials.

• 06:00 Care-seeking behavior associated with 'upper-GI symptoms'

  Read the story at EurekAlert
  Patients with upper gastrointestinal (GI) complaints visit their general practitioner more often than patients with other conditions. Researchers writing in the open-access journal BMC Family Practice found that people with dyspepsia, heartburn, epigastric discomfort and other upper-abdominal complaints had almost twice as many GP contacts, which were ultimately associated with problems in all organ systems. These patients were twice as frequently referred to specialist care and received twice as many prescriptions.

  Read the story at EurekAlert
  Salmonella are regarded as bad guys. Hardly a summer passes without severe salmonella infections via raw egg dishes or chicken that find their way into the media. But salmonella not only harm us -- in the future they may even help to defend us against cancer. The bacteria migrates into solid tumors, and makes it easier to destroy them. Furthermore, in laboratory mice they independently find their way into metastases, where they can also aid clearance.

• 06:00 Children with asthma more vulnerable to H1N1 virus

  Read the story at EurekAlert
  Nearly a dozen 7th graders with asthma were welcomed along with other classmates back to school today by a special guest who had a message for them about staying healthy -- Kathleen Sebelius, 21st Secretary of Health and Human Services. Secretary Sebelius met with students and their parents at Thurgood Marshall Elementary, one of 16 schools in Philadelphia that partners with the Merck Childhood Asthma Network, Inc. (MCAN) program partners to help students better manage their asthma.

• 06:00 Community gardens don't impact crime rate

  Read the story at EurekAlert
  Urban residents across the United States have dug in to create green spaces in their neighborhoods and the effects are positive -- increase in the number of owner-occupied dwellings, more personal income and rent increases in areas surrounding community gardens. But could the presence of green space contribute to lower crime levels in neighborhoods? Researchers investigated whether community gardens had an impact on reported property crimes in neighborhoods surrounding urban community gardens in Houston.
