...utor of these cells to researchers," he said. "The center is the source of the stem cells we use. "All of their donors are adults between the ages of 19 and 49. Essentially, each donor undergoes a medical procedure in which a small amount of bone marrow is extracted from his or her pelvic bone." Within th...

What can change in the brain? Electrical synapses, research shows

...he thalamus. The thalamus is a small region in the center of the brain responsible for relaying sensory information to the cerebral cortex, where it is transformed into memories and emotions, speech and movement. The thalamic reticular nucleus' role as a sort of switch, starting or stopping the flow of sen...

Anyway you slice it, tomatoes cut through drought with new gene

... Vegetable and Fruit Improvement Center. "Our center is good at moving genes into the different plants," Hirschisaid. "Dr. Park's job was to move this gene into the tomato." Hirschi, who's main research focus is "boosting nutrients in plants tomake them more nutritional for children," said the stud...

Engineers discover why toucan beaks are models of lightweight strength

...only very insignificant mechanical stresses in the center of the beak at the position of the hollow areas," said Meyers. "This is why I jokingly tell my students that toucans have a deep knowledge of mechanics. They don't bother adding structural support in a part of the beak that doesn't really need it." ...

UC Berkeley researchers create a biologically-inspired artificial compound eye

...es pierce the resin at angles that head toward the center of the dome, just like the converging ommatidia of an insect eye. Because the microlenses create the waveguides, each microlens is perfectly aligned with its waveguide. The self-alignment, self-writing processes are crucial to the creation of the ar...

Low-cost drug gaining favor for use in HIV-infected children in poor countries

...ghlights strong results from a single study at the center of mounting support for worldwide use of the low-cost drug Bactrim to help HIV-infected children in poor countries. The reviewers surveyed medical literature on the preventive use of Bactrim -- one of several brand names for the generic medicine cot...

Researchers reverse juvenile diabetes in animal model

...a federally funded national bone marrow HLA typing center within his lab.With this funding, Dr. Trucco and his team are able to continue their landmark research into improving the prediction of type 1 diabetes and understanding and managing its complications. Building on his discovery in 1994 that type 1 di...

Invasive species harms native hardwoods by killing soil fungus

...Harvard Forest, Harvard's ecology and conservation center in Petersham, Mass. "In North America, thousands of nonnative plants and animals have become established since European settlement and many more continue to be introduced. Some alien species cause little harm, while others can become very aggressive ...

World faces challenge as life expectancies lengthen, scientist says

... Current worries over the fate of Social Security center on the impending retirement of the Baby Boom generation. By 2035, the U.S. dependency ratio is projected to double from approximately 1:5 to just above 2:5. Increased boomer lifespans will add an alarming extra weight to an already sagging system. Fa...

How the brain learns to become addicted

... important regulatory peptides released by a brain center called the lateral hypothalamus. It was also known that orexins tend to activate circuitry in a region called the ventral tegmental area (VTA), known to be a critical site of neural adaptation, or plasticity, induced by addictive drugs. However, it w...

In the mind's eye: How the brain makes a whole out of parts

...pe, neurons in various areas of the brain's visual center respond to different components of that shape, almost instantaneously fitting them together like a puzzle to create an image that the individual then "sees" and understands, researchers at The Johns Hopkins University report. A team from the univers...

International HIV/AIDS trial finds continuous antiretroviral therapy superior to episodic therapy

Stem cell study for patients with heart attack damage seeks to regenerate heart muscle

...diac Catheterization Laboratory. Rush is the only center in Illinois participating in the trial. There are 15 other sites nationwide participating in the study. He explained that mesenchymal stem cells (MSC) are found in the adult bone marrow and have the potential to develop into mature heart cells and n...

Engineered mouse mimics cognitive aspects of schizophrenia

...irectly influencing the prefrontal cortex, a major center for cognitive function. To mimic the hyperactive dopamine machinery, the researchers created a genetically altered mouse strain in which dopamine receptors were overexpressed only in the striatum. What's more, they engineered the mouse strain so tha...

Aggression-related gene weakens brain's impulse control circuits

...tion-related brain structures, a hyperactive alarm center and under-active impulse control circuitry. The study identifies neural mechanisms by which this gene likely contributes to risk for violent and impulsive behavior through effects on the developing brain.
