Nanoparticles Found in Everyday Items Can Inhibit Fat Storage: Gold Nanoparticles Accelerate Aging

Apr. 18, 2013 — New research reveals that pure gold nanoparticles found in everyday items such as personal care products, as well as drug delivery, MRI contrast agents and solar cells can inhibit adipose (fat) storage and lead to accelerated aging and wrinkling, slowed wound healing and the onset of diabetes. The researchers, led by Tatsiana Mironava, a visiting assistant professor in the Department of Chemical and Molecular Engineering at Stony Brook University, detail their research in the journal Nanotoxicology.

Smoking from Hookah Not a Harmless Alternative to Cigarettes

Apr. 18, 2013 — Smoking tobacco through a hookah is a pastime gaining popularity among the college crowd, but many of them mistakenly believe that using the fragrant water pipe is less harmful than smoking cigarettes.

Why Do Babies Calm Down When They Are Carried?

Apr. 18, 2013 — Parents know that crying babies usually calm down when they are picked up and carried, but why is that? In a study published today, researchers from the RIKEN Brain Science Institute show that human babies and mouse pups alike automatically relax deeply when they are carried.

Gravação magnética quântica é 1.000 vezes mais rápida

Redação do Site Inovação Tecnológica - 22/04/2013

Como a gravação é feita com os pulsos de laser ainda interagindo com os momentos magnéticos, a comutação magnética é gerada quantum-mecanicamente - não termicamente. Isto abre a possibilidade de criar memórias na faixa dos terahertz.[Imagem: Ames Laboratory]

Parents Can Help Their Children Avoid Alcohol Pitfalls During Transition from High School to College

Apr. 16, 2013 — Prior research has shown that the transition from high school to college is a particularly vulnerable time, associated with increased alcohol use and risk of negative alcohol-related consequences. While studies have examined the effectiveness of prevention programs to address this problem, few have examined which students may benefit the most. A study of student characteristics has found that parent-based interventions (PBIs) can be effective even among those students feeling high peer pressure to drink alcohol.

Memory, the Adolescent Brain and Lying: The Limits of Neuroscientific Evidence in the Law

Apr. 16, 2013 — rain scans are increasingly able to reveal whether or not you believe you remember some person or event in your life. In a new study presented at a cognitive neuroscience meeting today, researchers used fMRI brain scans to detect whether a person recognized scenes from their own lives, as captured in some 45,000 images by digital cameras. The study is seeking to test the capabilities and limits of brain-based technology for detecting memories, a technique being considered for use in legal settings.
