Dalai Lama, top scientists to discuss science & clinical applications of meditation

...de an opportunity for scientists whose research is focused on basic mind-brain-body interactions to learn more about meditation and to contribute to an ongoing dialogue about the mechanisms by which meditation may influence physical and mental health," Engle added. This event also provides medical professio...

Many smokers fail to quit after cancer diagnosis

...pse. Treatment for this addiction has largely been focused on healthy smokers and is critically dependent on smoker motivation. The diagnosis of cancer, according to research, is a strong motivator for many smokers and thus, provides a window of opportunity to begin treatment for smoking addiction. Led by E...

Prenatal exposure to marine toxin causes lasting damage

...man consumption. Earlier studies in animals have focused on lethal and highly toxic doses of domoic acid. Such exposures cause extensive damage to the hippocampus, a part of the brain involved in learning and memory. More recent reports examining the effects of a range of doses have found highly reproducib...

A bug's life: Exceptional genomic stability yet rapid protein evolution in a carpenter ant mutualist

...st can live without the other. Wernegreen's group focused on the bacterium Blochmannia, which has lived inside Camponotus and related ant genera for the past 30 million years or more. The bacteria may utilize the ant host for basic metabolic functions, including the initiation of DNA replication. In turn, t...

Chernobyl: The true scale of the accident

...sed emergency personnel. The Report also calls for focused screening of children exposed to radioiodine for thyroid cancer and highly exposed clean-up workers for non-thyroid cancers. However, existing screening programs should be evaluated for cost-effectiveness, since the incidence of spontaneous thyroid c...

UT Southwestern researchers unravel control of growing blood vessels

... in Pediatric Oncology. He and fellow researchers focused on a molecule called Foxo4, to see whether it might control myocardin; they found that it turns off myocardin, thus allowing smooth muscle cells to stop contracting and grow. The level of Foxo4, in turn, increases or decreases depending on what kind ...

Einstein scientists discover how protein crucial for motion is synthesised at the right place in the cell

...nger and Dr Stefan Huettelmaier, the research team focused on migrating fibroblast cells important in wound healing. To move towards a wound, these cells manufacture the protein actin, which polymerizes into long filaments that push the cell's membrane outward to form protrusions. The team's previous work ...

Restoring silenced suppressor gene kills lung-cancer cells

... strategy for treating the disease. The research focused on a gene known as WWOX, which is lost or silenced in a large majority of lung cancers, and in cancers of the breast, ovary, prostate, bladder, esophagus and pancreas. The work was led by scientists at The Ohio State University Comprehensive Cancer C...

Researchers offer proof-of-concept for Altered Nuclear Transfer

...Alexander Meissner, a graduate student in his lab, focused on a gene called Cdx2, which enables an embryo to grow a placenta. In order to create a blastocyst that cannot implant in a uterus, the researchers disabled Cdx2 in mouse cells. They accomplished this with a technique called RNA interference, or RN...

Researchers identify molecular anchor that allows bacterial invasion of central nervous system

...eningitis." Doran and Nizet noted that the study focused on how bacteria can begin the invasion process, and that additional Streptococcus toxins and the body's own immune response also contribute to the development of meningitis. In their ongoing efforts, the researchers are looking at all of these factor...

A new window into structural plasticity in the adult visual cortex

... circuits under normal conditions. The authors focused on the surface layers of the neocortex. To allow d...hysical changes in the neurons. Many studies have focused on pyramidal neurons--excitatory neurons that promote neuron firing--but few have focused on the pos...

University of Delaware researchers develop cancer 'nanobomb'

...to treat human beings. "Make no mistake, we are focused on eradicating cancer," Panchapakesan said, explaining that the nanobombs are the result of work over the past two years with carbon nanotubes, which are atoms of carbon arranged in tubular form. Originally, he said, the research team was looking ...

MIT researcher finds neuron growth in adult brain

Science's Breakthrough of the Year: Watching evolution in action

...he seasonal development of flowers. Other research focused on a gene involved in stimulating flowering, and another study highlighted a surprising cache of RNA. The Nature of Neutron Stars: In 2005, new instruments yielded vivid insights into the most violent behaviors of neutron stars. A short, intense pul...

New study examines how sense of smell affects mating and aggression in mice

...es behaviors in humans," he adds. The UCSF study focused on the sexual and aggressive behaviors triggered by the rodent's olfactory system. The findings are published in the December issue of Nature Neuroscience. According to Shah, researchers traditionally have thought rodents detect pheromones throug...

Sperm stem cells closer to being like embryonic stem cells

...similar to embryonic stem cells. That's what we're focused on now." Pluripotent cells have the potential to change into many other types of cells in the body, such as liver cells and brain cells. Their potential use in humans to treat diseases like diabetes and Parkinson's is controversial because current...

Islands in the Genome Promote Speciation

...l differences in mosquitoes. Turner and colleagues focused on two forms, A. gambiae M and A. gambiae S, that sometimes mate and create hybrid forms in nature. While it's unclear whether the forms can produce fertile hybrid offspring in the wild, the progeny of lab matings appear to have no problems with fert...

Adult stem cells aid recovery in animal model of cerebral palsy
