• 20:05 New book tutors future presidents and public on science behind the headlines

  Read the story at PhysOrg
  In the event of a standoff between the United States and Iran over uranium enrichment, would Barack Obama, if elected president, know enough about the physics of nuclear weapons to assess the threat? In leading the nation toward reduced greenhouse gas emissions, would John McCain as president understand which technologies would best decrease America's carbon footprint?

• 20:05 New insights into centre of the Earth

  Read the story at PhysOrg
  A new observation of the very deepest part of the Earth, the solid inner core, has been reported this week in Nature. The team from the University of Bristol also observed intriguing evidence of a ‘texture` in the solid iron that may reflect the patterns left as the swirling liquid iron of the outer core freezes to form the inner core.

• 20:05 Personalized immunotherapy to fight HIV/AIDS

  Read the story at PhysOrg
  For a long time, the main obstacle to creating an AIDS vaccine has been the high genetic variability of the HIV virus. Dr. Jean-Pierre Routy and his team from the Research Institute of the McGill University Health Centre (MUHC), in collaboration with Dr. Rafick Sékaly from the Université de Montréal, have overcome this difficulty by designing a personalized immunotherapy for HIV-infected patients. The team's findings were presented on August 5 at the XVII International AIDS Conference in Mexico City.

• 20:05 Researchers to study lyme-like illness in Texas

  Read the story at PhysOrg
  Tao Lin, D.V.M., and Steven J. Norris, Ph.D., both with the Department of Pathology and Laboratory Medicine at The University of Texas Medical School at Houston, have been named grant recipients of the Norman Hackerman Advanced Research Program (ARP) by the Texas Higher Education Coordinating Board. They will receive $150,000 over two years to support their research into conflicting reports about the infectious nature and causative agent of Southern-Tick Associated Rash Illness (STARI) in Texas and other southern states.

• 20:05 Study finds way to prevent protein clumping characteristic of Parkinson's disease

  Read the story at PhysOrg
  Researchers at the University of Pennsylvania School of Medicine have identified a protein from a most unlikely source -- baker's yeast -- that might protect against Parkinson's disease. More than a million Americans suffer from Parkinson's disease, and no treatments are available that fundamentally alter the course of the condition. By introducing the yeast protein Hsp104 into animal models of Parkinson's disease, researchers prevented protein clumping that leads to nerve cell death characteristic of the disorder.

• 20:05 Study shows that surgical weight loss does not eliminate obstructive sleep apnea

  Read the story at PhysOrg
  A study in the August 15 issue of the Journal of Clinical Sleep Medicine shows that surgical weight loss results in an improvement of obstructive sleep apnea (OSA), but most patients continue to have moderate to severe OSA one year after undergoing bariatric surgery. .Results of this study suggest that it is the severity of the condition, rather than a patient's presurgical weight, that determines if OSA will be resolved.

• 20:05 True properties of carbon nanotubes measured

  Read the story at PhysOrg
  For more than 15 years, carbon nanotubes (CNTs) have been the flagship material of nanotechnology. Researchers have conceived applications for nanotubes ranging from microelectronic devices to cancer therapy. Their atomic structure should, in theory, give them mechanical and electrical properties far superior to most common materials.

• 19:00 Parents' expectations, styles can harm college students' self-esteem

  Read the story at PhysOrg
  Mom and Dad are going to flip out over my 3.3 GPA and failure to land a top internship. Such anxieties, common among college students, can harm self-esteem and make it more difficult to adjust to school. But a new University of Central Florida study has found that students' anxieties often are based on exaggerated perceptions of what their parents expect.

• 14:45 Asthma in boys may be just a phase, but for girls it may be there to stay

  Read the story at PhysOrg
  Boys may be more apt than girls to have childhood asthma, but, when compared to girls, they are also more likely to grow out of it in adolescence and have a decreased incidence of asthma in the post-pubertal years. This indicates that there may be a buried mechanism in asthma development, according to a prospective study that analyzed airway responsiveness (AR) in more than 1,000 children with mild to moderate asthma over a period of about nine years.

• 13:40 Big-brained animals evolve faster

  Read the story at PhysOrg
  Ever since Darwin, evolutionary biologists have wondered why some lineages have diversified more than others. A classical explanation is that a higher rate of diversification reflects increased ecological opportunities that led to a rapid adaptive radiation of a clade.

• 23:45 Lessons from yeast: A possible cure for Parkinson's disease?

  Read the story at PhysOrg
  Parkinson disease (PD) is a debilitating and lethal neurodegenerative disease, for which there is currently no cure. It is caused by the progressive loss of nerve cells that produce the chemical dopamine and is characterized by the accumulation of abnormal aggregates of a protein called alpha-syn in these dopaminergic nerve cells.
