Personality influences placebo response

Researchers have found that resilient, altruistic, and straightforward individuals are significantly more likely to respond to a sham painkilling or placebo injection than those who are angry and hostile.

Synthetic membrane channels can be constructed through DNA nanotechnology

As reported in the journal Science, physicists at the Technische Universitaet Muenchen (TUM) and the University of Michigan have shown that synthetic membrane channels can be constructed through "DNA nanotechnology."

New pathway appears to play a major role in information processing in the brain

Scientists at The Scripps Research Institute (TSRI) have identified a new pathway that appears to play a major role in information processing in the brain. Their research also offers insight into how imbalances in this pathway could contribute to cognitive abnormalities in humans.

UCI study reveals novel immune system response to bacterial infections

UC Irvine biologists have discovered that fats within cells store a class of proteins with potent antibacterial activity, revealing a previously unknown type of immune system response that targets and kills bacterial infections.

Communications down in anesthetized brain

Two studies indicate that inhaled anesthetics disrupt communication between distant cortical areas before directly activating sleep-inducing neuronal circuitry.

Selective blocking of HDAC11 inhibitor would act exclusively on tumor cells

Several substances inhibiting so-called HDAC enzymes have been studied in trials searching for new anti-cancer drugs in recent years. "Trials have shown that HDAC inhibitors are very effective in arresting growth of cultured cancer cells. But apart from a very rare type of lymphoma, these drugs unfortunately do not clinically affect malignant tumors," says Prof. Dr. Olaf Witt, who heads a research department at DKFZ and is pediatrician at the Center for Child and Adolescent Medicine of Heidelberg University Hospital.

Researchers unlock complex cellular mechanics that instruct glial progenitor cells to divide

In a new study appearing this month in the Journal of Neuroscience, researchers have unlocked the complex cellular mechanics that instruct specific brain cells to continue to divide. This discovery overcomes a significant technical hurdle to potential human stem cell therapies; ensuring that an abundant supply of cells is available to study and ultimately treat people with diseases.

STAT3 transcription factor remains in the axon of nerve cells to help prevent neurodegeneration

A study in The Journal of Cell Biology shows how a transcription factor called STAT3 remains in the axon of nerve cells to help prevent neurodegeneration. The findings could pave the way for future drug therapies to slow nerve damage in patients with neurodegenerative diseases.

Researchers identify genes linked to serous endometrial cancer

Researchers have identified several genes that are linked to one of the most lethal forms of uterine cancer, serous endometrial cancer.

Idea of nuclear reprogramming holds promise for repairing damaged tissue

The idea of taking a mature cell and removing its identity (nuclear reprogramming) so that it can then become any kind of cell, holds great promise for repairing damaged tissue or replacing bone marrow after chemotherapy.

Researchers use baker's yeast to identify new therapies for Lou Gehrig's disease

Amyotrophic lateral sclerosis, also called Lou Gehrig's disease, is a devastatingly cruel neurodegenerative disorder that robs sufferers of the ability to move, speak and, finally, breathe.

Researchers investigate unique features of arcuate neurons in the hypothalamus

Maintaining a healthy body weight may be difficult for many people, but it's reassuring to know that our brains and bodies are wired to work together to do just that-in essence, to achieve a phenomenon known as energy balance, a tight matching between the number of calories consumed versus those expended. This careful balance results from a complex interchange of neurobiological crosstalk within regions of the brain's hypothalamus, and when this "conversation" goes awry, obesity or anorexia can result.

UNM Cancer Center scientist to continue histone modification study

While every one of our cells contains all of our genetic information, each type of cell uses only specific parts of that information to make its proteins. Uncovering more about the mechanism that directs which particular pieces of genetic information the cell uses is the research focus of Mary Ann Osley, PhD, University of New Mexico Professor of Molecular Genetics and Microbiology and Co-Leader of the Cancer Biology and Biotechnology Program at the UNM Cancer Center.

Study to examine possible link between mitochondrial DNA and ovarian cancer

Ovarian cancer is a deadly disease. With no overt symptoms and no screening tests to catch it early, ovarian cancer is often detected at stage 3 or later. By then, it can be very aggressive and may have spread beyond the ovaries into other organs. Many women eventually succumb to it; the five-year survival rate for a stage 3 ovarian cancer diagnosis is only 34 percent.

Research team identifies turbo switch in the vital calcium pump in our body's cells

A Danish-British research team has discovered a turbo switch in the vital calcium pump in our body's cells. In studies at the X-ray source DORIS at Deutsches Elektronen-Synchrotorn DESY in Hamburg and the European Synchrotron Radiation Facility ESRF in Grenoble the team discovered that the on-off switch of the pump has a previously unknown third position, which switches the pump into a turbo gear.

Stem cell study may help to unravel how genetic mutation leads to Parkinson's symptoms

By reprogramming skin cells from Parkinson's disease patients with a known genetic mutation, researchers at the Salk Institute for Biological Studies have identified damage to neural stem cells as a powerful player in the disease.

Study shows children with low levels of gene activity develop anxious dispositions

Decreased activity of a group of genes may explain why in young children the "fear center" of the anxious brain can't learn to distinguish real threats from the imaginary, according to a new University of Wisconsin study.

New book focuses on Wnt signaling

Wnt proteins are signaling molecules that play critical roles during embryonic development and in the regeneration of adult tissues. They bind to Frizzled and LRP family receptors on the cell surface, triggering a series of events that cause beta-catenin to enter the nucleus and activate transcription factors that control cell fate and cell proliferation. Mutations in components of the Wnt pathway lead to developmental defects and are common in cancer.

Salk findings on cold virus proteins may spur new cancer treatments

Cold viruses generally get a bad rap----which they've certainly earned----but new findings by a team of scientists at the Salk Institute for Biological Studies suggest that these viruses might also be a valuable ally in the fight against cancer.

Mephedrone and memory loss: an interview with Craig Motbey

Mephedrone is a fairly new designer drug which has been around for a few years. It exploded in popularity in Europe (and particularly in the UK) before it started to spread in a major way elsewhere.
