Professor Guillermo Bazan and a team of postgraduate researchers at UC Santa Barbara's Center for Polymers and Organic Solids today announced a major advance in the synthesis of organic polymers for plastic solar cells.

Migraine sufferers more prone to hangover headache
Migraine sufferers, beware. You may be more prone to an alcohol-induced headache after a night of drinking, according to researchers from the Jefferson Headache Center.

Performance reviews are raising council standards, say researchers
Performance assessment schemes aimed at making local authorities into more effective organisations are having the desired effect, according to new research released by the Economic and Social Research Council.

Fracture zones endanger tombs in Valley of Kings
Ancient choices made by Egyptians digging burial tombs may have led to today's problems with damage and curation of these precious archaeological treasures, but photography and detailed geological mapping should help curators protect the sites, according to a Penn State researcher.

Metals could forge new cancer drug
Drugs made using unusual metals could form an effective treatment against colon and ovarian cancer, including cancerous cells that have developed immunity to other drugs, according to research at the University of Warwick and the University of Leeds in the UK.

U of C chemists discover recipe to design a better type of fuel cell
University of Calgary chemists Jeff Hurd and George Shimizu have taken the science behind a specific type of fuel cell towards a higher level of design.

APP -- Good, bad or both?
New data about amyloid precursor protein, or APP, a protein implicated in development of Alzheimer's disease, suggests it also may have a positive role -- directly affecting learning and memory during brain development.

A major step in making better stem cells from adult tissue
A team led by scientists from the Scripps Research Institute has developed a method that dramatically improves the efficiency of creating stem cells from human adult tissue, without the use of embryonic cells.

What caused implantable venous access device failure in cancer patients?
A totally implantable venous access device (TIVAD) is necessary for cancer patients who require long-term intravenous chemotherapy.

Small mechanical forces have big impact on embryonic stem cells
Applying a small mechanical force to embryonic stem cells could be a new way of coaxing them into a specific direction of differentiation, researchers at the University of Illinois report.

Geologists point to outer space as source of the Earth's mineral riches
According to a new study by geologists at the University of Toronto and the University of Maryland, the wealth of some minerals that lie in the rock beneath the Earth's surface may be extraterrestrial in origin.

Exercise can aid recovery after brain radiation
Exercise is a key factor in improving both memory and mood after whole-brain radiation treatments in rodents, according to data presented by Duke University scientists at the Society for Neuroscience meeting on Oct.

What's the clonality status and allelotype of focal nodular hyperplasia?
Focal nodular hyperplasia (FNH) is considered a hyperplastic lesion found in an otherwise normal liver, its clonality status has not been elucidated and the development of hepatocyte nodules within the involved parenchyma needs to be explained.

Fine-tuning treatments for depression
New research clarifies how neurotransmitters like norepinephrine, serotonin, and dopamine, are regulated -- a finding that may help fine-tune therapies for depression.

Stanford study identifies cellular mechanism that causes lupuslike symptoms in mice
Macrophages, the scavenger cells of the body's immune system, are responsible for disposing of dying cells.

Violence between couples is usually calculated, and does not result from loss of control
Violence between couples is usually the result of a calculated decision-making process and the partner inflicting violence will do so only as long as the price to be paid is not too high.

New chromosomal abnormality identified in leukemia associated with Down syndrome
Researchers identified a new chromosomal abnormality in acute lymphoblastic leukemia that appears to work in concert with another mutation to give rise to cancer.

Neuroscience 2009 highlights new research on exercise, music and the brain
Research presented today at Neuroscience 2009, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news about brain science and health, provides a better understanding of the brain, nervous system, and related disorders.

Treatment for inflammatory bowel disease increases the risk of infection-related cancers
Patients with Crohn's disease or ulcerative colitis (collectively referred to as inflammatory bowel disease) regularly receive treatment with thiopurine drugs to maintain remission.

Fate Therapeutics announces creation of small molecule platform for commercial-scale reprogramming
Fate Therapeutics announced today the generation of human induced-pluripotent stem cells using a combination of small molecules that significantly improves the speed and efficiency of reprogramming.

Angiochem crosses BBB, shows safety, efficacy in Phase 1/2 brain cancer studies
Angiochem Inc. developing drugs uniquely capable of crossing the blood-brain barrier, announced today that its lead drug candidate, ANG1005, has demonstrated a favorable safety and efficacy profile in more than 100 patients with brain cancer from two separate Phase 1/2 clinical studies in patients with progressive gliomas, including recurrent glioblastoma, and in patients with progressive brain metastases.

Time in a bottle: Scientists watch evolution unfold
A 21-year Michigan State University experiment that distills the essence of evolution in laboratory flasks not only demonstrates natural selection at work, but could lead to biotechnology and medical research advances, researchers said.

Study predicts seabed response to climate change
CSIRO scientists have produced the first preliminary predictions of the potential impact of climate change on the Australian seabed.
