Coal-generated CO2 captured in Australia -- a first

CSIRO Energy Technology Chief, Dr David Brockway, said the milestone followed the Garnaut Report's recognition that Australia has an important role to play in developing low emission coal technologies such as PCC.

"PCC uses a liquid to capture CO2 from power station flue gases and can potentially reduce CO2 emissions from existing and future coal-fired power stations by more than 85 per cent," he said.

Brain activity encodes reward magnitude and delay during choice

Good things may come to those who wait, but research has proven that humans and animals actually prefer an immediate rather than a delayed reward. Now, a study published by Cell Press in the July 10 issue of the journal Neuron reveals how a decision-making region of the brain encodes information associated with the magnitude and delay of rewards.

Ionophore reverses Alzheimer's within days in mouse models

Scientists report a remarkable improvement in Alzheimer's transgenic mice following treatment with a new drug. The study, published by Cell Press in the July 10th issue of the journal Neuron, provides the first demonstration that an ionophore, a compound that transports metal ions across cell membranes, can elicit rapid and pronounced improvement in neuropathology and cognitive function in mouse models of Alzheimer's Disease (AD).

10 people killed by new CJD-like disease

A NEW form of fatal dementia has been discovered in 16 Americans, 10 of whom have already died of the condition. It resembles Creutzfeldt-Jakob disease - with patients gradually losing their ability to think, speak and move - but has features that make it distinct from known forms of CJD.

Avatars as communicators of emotions

Current interactive systems enable users to communicate with computers in many ways, but not taking into account emotional communication. A PhD thesis presented at the University of the Basque Country puts forward the use of avatars or virtual Internet personages as an efficient form of non-verbal communication, principally focusing on emotional aspects.

Big brains arose twice in higher primates

After taking a fresh look at an old fossil, John Flynn, Frick Curator of Paleontology at the American Museum of Natural History, and colleagues determined that the brains of the ancestors of modern Neotropical primates were as small as those of their early fossil simian counterparts in the Old World. This means one of the hallmarks of primate biology, increased brain size, arose independently in isolated groups—the platyrrhines of the Americas and the catarrhines of Africa and Eurasia.

Protein on 'speed' linked to ADHD

A genetic change in the dopamine transporter – one of the brain's dopamine-handling proteins – makes it behave as if amphetamine is present and "run backward," Vanderbilt University Medical Center investigators report this week in The Journal of Neuroscience.

IVF does not increase risk of developmental disorders in children

Does a gene variant make women more prone to alcoholism?

A particular gene variant might make women more susceptible to alcoholism. At least, a study carried out by the Universities of Bonn and Sweden's Karolinska Institute makes this a plausible conclusion. Accord-ing to this, a gene in the endorphin metabolism is altered in a typical fashion more often in women alcoholics than in healthy women. In mice too, endorphins seem to play an important role in the amount of alcohol consumed, particularly among females.

Can tomatoes carry the cure for Alzheimer's?

The humble tomato could be a suitable carrier for an oral vaccine against Alzheimer's disease, according to HyunSoon Kim from the Korea Research Institute of Bioscience and Biotechnology (KRIBB) in Korea and colleagues from Digital Biotech Inc. and the Department of Biological Science at Wonkwang University. Although their research (1), just published online in Springer's journal Biotechnology Letters, is still in the early stages, it is a promising first step towards finding an edible vaccine against the neurodegenerative disease.

UNC study ties ending moderate drinking to depression

CHAPEL HILL – Scientific evidence has long suggested that moderate drinking offers some protection against heart disease, certain types of stroke and some forms of cancer.

But new research shows that stopping drinking – including at moderate levels – may lead to health problems including depression and a reduced capacity of the brain to produce new neurons, a process called neurogenesis.

The findings from the Bowles Center for Alcohol Studies at the University of North Carolina at Chapel Hill appear online in the journal Neuropsychopharmacology.

Orange County research program aims to improve severe trauma survival rates

Irvine, Calif., July 8, 2008 — A method of resuscitation for victims of severe traumatic injury will be the subject of a clinical trial to be undertaken by a team of Orange County emergency care providers.

The Orange County Resuscitation Outcomes Consortium will include UC Irvine, Orange County Health Care Agency, Mission Hospital, Western Medical Center Santa Ana, Orange County Fire Authority, and fire departments from other Orange County cities.

Alcoholism-associated molecular adaptations in brain neurocognitive circuits

After many years of heavy drinking, alcohol produces pathological alterations in the brain. In many alcoholics these changes culminate in massive social deterioration and disorders of memory and learning. Severe cognitive impairments occur in approximately 10% of heavy drinkers. Alcoholic dementia is the second leading course of adult dementia in the Western countries, accounting for 10% of the cases, and still represents an unresolved problem. So far no effective pharmacotherapy for memory problems in alcoholics is available.

Neurogenesis in the adult brain: The association with stress and depression

The brain is the key organ in the response to stress. Brain reactions determine what in the world is threatening and might be stressful for us, and regulate the stress responses that can be either adaptive or maladaptive. Chronic stress can affect the brain and lead into depression: Environmental stressors related to job or family situation are important triggers of depressive episodes and major life events such as trauma or abuse amongst the most potent factors inducing depression.

The first autism disease genes

The autistic disorder, a neurodevelopmental disease first described in 1943, represents a challenge for treatment and a puzzle for research. Alongside Asperger syndrome, a milder form of the disorder, autism is classified in the continuum of various Autism Spectrum Disorders (ASD), all of which are characterized by deficits in language, social interaction, and a strangely restricted and repetitive behaviour (stereotypy). Disease onset occurs during the first three years of life.
