Science Sunday: Wrap-up of recent advancements in science from EurekAlert!
Animal studies suggest vegetables may reduce hardening of arteries:
New research suggests one reason vegetables may be so good for us - a study in mice found that a mixture of five common vegetables reduced hardening of the arteries by 38 percent compared to animals eating a non-vegetable diet. Conducted by Wake Forest University School of Medicine, the research is reported in the current issue of the Journal of Nutrition.
Bacterium takes a shine to metals:
Exposed metal surfaces are highly vulnerable to corrosion, but paint or other protective coatings can interfere with some uses, as well as add significant costs. An organism named Shewanella oneidensis MR-1 protected copper as well as plastic film does in tests at the USC Viterbi School of Engineering.
Cracking a virus protection shield:
Researchers from the Institut de Virologie Mol.culaire et Structurale (IVMS) and the Outstation of the European Molecular Biology Laboratory (EMBL) in Grenoble have obtained a detailed structural picture of a protein that allows the rabies virus to withstand the human immune response and survive and replicate in our cells. The study that is published in this week's online edition of Science suggests new potential drug targets in rabies and sheds light on how similar approaches can help fighting other viral diseases.
New study: Pine bark extract reduces ADHD symptoms in children:
A new study to be published in the June 17 edition of the journal of European Child & Adolescent Psychiatry shows a significant reduction of Attention-Deficit/Hyperactivity Disorder (ADHD) symptoms in children after supplementing with Pycnogenol. (pic-noj-en-all), an antioxidant plant extract from the bark of the French maritime pine tree, everyday for one month.
Northwestern team develops 'MRI' for fuel cells:
As gasoline prices top $3 a gallon in major cities, the drive toward increasing energy efficiency and reducing air pollution has accelerated, and the development of fuel cells has become a major focus worldwide. Now a research team led by a Northwestern University materials scientist has produced the first three-dimensional images of the interior of a fuel cell -- providing a new tool for the study and development of fuel cells.
Growth factor triggers growth of new blood vessels in the heart:
The newest concept for treating coronary artery disease is to induce hearts to grow their own new blood vessels to bypass damaged tissue or clogged arteries.
Researchers offer clues to how leaf patterns are formed:
Pick up a leaf and it is hard not to notice the pattern made by the veins. For years, biologists, mathematicians and even poets and philosophers have tried to decipher the rules and regulations behind those varied designs and now new research published in part at the University of Alberta offers a big clue to how those patterns are formed.
An adaptive interface for controlling the computer by thought:
Controlling a computer just by thought is the aim of cerebral interfaces. The engineer from Pamplona, Carmen Vidaurre Arbizu, has designed a totally adaptive interface that improves the performance of currently existing devices in.
Infected for life:
Researchers at the University of Pennsylvania School of Medicine have discovered part of the reason why cold sores, caused by a herpes virus, come back again and again. The new study points to a small RNA molecule, called a microRNA as the culprit that keeps the latent virus-infected cell alive. These findings could one day lead to a new way to fight the virus and offers the first target for intervention in the latent infection.
Diamond by-product of hydrogen production and storage method:
There may not be a pot of gold at the end of the rainbow, but there appears to be nanocrystalline diamonds at the end of a process to produce and store hydrogen using anthracite coal.
How plants avoid feeling the burn:
Too much sun - for plants as well as people - can be harmful to long-term health. But to avoid the botanical equivalent of "lobster tans," plants have developed an intricate internal defense mechanism, called photoprotection, which acts like sunscreen to ward off the sun's harmful rays. Now, ASU scientists have found a way to measure for the first time the electrical conductance within such an important biomolecule and produce a new discovery which shatters the prevailing view as to how photoprotection works.
