New Techniques Study The Brain's Chemistry, Neuron By Neuron
Researchers at the University of Illinois at Urbana-Champaign have developed tools for studying the chemistry of the brain, neuron by neuron. The analytical techniques can probe the spatial and temporal distribution of biologically important molecules, such as vitamin E, and explore the chemical messengers behind thought, memory and emotion. Minimally Invasive Solid Tumor Biopsy May Replace Surgery To Get Diagn
Inserting biopsy needles through the skin appears to be a safe and reliable alternative to surgery for obtaining diagnostic samples of a suspected solid tumor in children, according to results of a study by investigators at St. Jude Children's Research Hospital. Family News Network of the International Committee of the Red Cross: H

Cancer cells treated with carbon nanotubes can be destroyed by non-invasive radio waves that heat up the nanotubes while sparing untreated tissue, scientist have found. Laser, Machining, Used To Create Precision Parts Layer By Layer
Researchers are perfecting a technique for manufacturing parts that have complex shapes and precision internal features by depositing layers of powdered materials, melting the powder with a laser and then immediately machining each layer. The new method can be used for creating parts made of advanced materials such as ceramics, which are difficult to manufacture and cannot be machined without first using a laser to soften the material. Sex, and Sex-Ed, Doesn't Stop
New York seniors get up to speed on sexual health and safer sex practices as sex tech extends sexual function to match sexual imagination. In Sex Drive Daily. Depression, Not Antidepressants, Increases Mortality Risks In Heart Fa
People who are depressed have an increased risk of dying from heart failure, and a new study by Duke University Medical Center researchers may help explain why. Bacteria engineered to turn carbon dioxide into liquid fuel
Global climate change has prompted efforts to drastically reduce emissions of carbon dioxide, a greenhouse gas produced by burning fossil fuels. In a new approach, researchers have genetically modified a cyanobacterium to consume carbon dioxide and produce a liquid fuel precursor to isobutanol, which holds great potential as a gasoline alternative. The reaction is powered directly by energy from sunlight, or photosynthesis. Earth's Early Ocean Cooled More Than A Billion Years Earlier Than Thou
The global ocean covering the Earth 3.4 billion years ago was far cooler than has been thought, according to researchers who analyzed isotope ratios in rocks formed on that ancient ocean floor. Instead of a hot primordial soup, much more tepid temperatures prevailed. Cooler temperatures may have had effects on the evolution of the early atmosphere and could have opened the door to an earlier spread of photosynthetic life forms across the planet.
