Genetic Abnormalities Identified in Pluripotent Stem Cell Lines
By Debra Kain A multinational team of researchers led by stem cell scientists at the University of California, San Diego School of Medicine and Scripps Research Institute has documented specific genetic abnormalities that occur in human embryonic (hESC) and induced pluripotent stem cell (iPSC) lines.

Faulty 'off-switch' stops children with ADHD from concentrating
Faulty ’off-switch’ stops children with ADHD from concentrating
PA 04/11 Brain scans of children with attention-deficit/hyperactivity disorder (ADHD) have shown for the first time why people affected by the condition sometimes have difficulty in concentrating. The study, by experts at The University of Nottingham, may explain why parents often say that their child can maintain concentration when they are doing something that interests them, but struggles with boring tasks.

Advance makes MRI scans more than seven times faster
BERKELEY — An international team of physicists and neuroscientists has reported a breakthrough in magnetic resonance imaging that allows brain scans more than seven times faster than currently possible. In a paper that appeared Dec. 20 in the journal PLoS ONE , a University of California, Berkeley, physicist and colleagues from the University of Minnesota and Oxford University in the United Kingdom describe two improvements that allow full three-dimensional brain scans in less than half a second, instead of the typical 2 to 3 seconds.

Findings could lead to new test for Obsessive Compulsive Disorder (OCD)
Researchers from the University of Sydney's Centenary Institute have identified gene mutations that impair kidney function leading to a rare kidney disorder known as dicarboxylic aminoaciduria (DA). The same gene, which is also crucial for normal brain function, has been connected with obsessive compulsive-disorder (OCD).

Untreated ADHD common amongst male convicts
Men serving long prison sentences surprisingly often have a history of unrecognised and untreated ADHD, despite having had considerable problems since childhood. This according to a recent study published by a team of researchers from Karolinska Institutet in the scientific journal BMC Psychiatry. Working with the Swedish Prison and Probation service, the researchers conducted a comprehensive survey of the inmates of Norrtälje prison in order to ascertain the extent of ADHD and prepare the ground for trials of effective therapies.

Left wing or right wing It’s written in the brain
If you listen to Radio 4's Today Programme on any given day, you'll inevitably hear a spectrum of politic views from socialist through liberal to conservative. You may find yourself agreeing with the interviewee or irked by their politics depending on your own political persuasion. Liberals and conservatives may find themselves disagreeing on issues as wide-ranging as the future of the NHS, the UK's involvement in Afghanistan and whether students should pay tuition fees at university, but could these differences be a result of different brain structures?

Paternal Diet Can Affect Genes And Health Of Offspring, Research Suggests
Dec. AUSTIN, Texas — Environmental influences experienced by a father can be passed down to the next generation, "reprogramming" how genes function in offspring, scientists at The University of Texas at Austin and the University of Massachusetts Medical School (UMMS) have discovered. A new study published this week in Cell shows environmental cues — in this case, diet — influence genes in mammals from one generation to the next, evidence that until now has been sparse.

Brain gene makes a female develop as a male
Australian scientists have discovered that changes to a gene involved in brain development can lead to testis formation and male genitalia in an otherwise female embryo. Lead researcher Professor Andrew Sinclair of the University of Melbourne and the Murdoch Childrens Research Institute said the breakthrough would improve diagnosis and clinical management of patients with disorders of sex development (DSD).

Scientists reveal how biological activity is regulated in fruit fly and roundworm genomes
Scientists today published an almost complete catalog of the fruit fly and roundworm's functional elements ' sequences in the genome that carry out the instructions in the genome and determine which genes are turned on and off at various times in different cells. Scientists can now study functional elements in the fruit fly and roundworm that are also present in the human genome to better understand human medical conditions.

Alzheimer's changes detectable in healthy elderly
Alzheimer’s changes detectable in healthy elderly
A team of UCL researchers, part-funded by the Alzheimer's Research Trust, has discovered that combining spinal fluid testing with MRI scans could provide an early indication of a person's risk of developing Alzheimer?s. The approach could allow scientists to test treatments or preventions far earlier in the disease, when experts believe they could be more effective.

Countering memory loss in the immune system
After recovering from a cold or other infection, your body's immune system is primed to react quickly if the same agent tries to infect you. White blood cells called memory T cells specifically remember the virus or bacterium and patrol the body looking for it. Vaccines work on the same principle: Harmless fragments of a virus or bacterium provoke the immune system to generate memory T cells that can attack the real thing later on.

Chronic Fatigue Syndrome not caused by XMRV
Chronic Fatigue Syndrome not caused by XMRV
Links: Wellcome Trust Professor Greg Towers Wellcome Trust Sanger Institute A virus previously thought to be associated with chronic fatigue syndrome is not the cause of the disease, a detailed study led by UCL scientists has shown. The research shows that cell samples used in previous research were contaminated with the virus identified as XMRV and that XMRV is present in the mouse genome.

How the eye builds circuits to detect motion
Scientists could explain how the eye creates circuits to analyze motion. The detection of motion in the retina is based on circuit asymmetry, a fundamental computational principle in the brain.

Emotional intelligence peaks as we enter our 60s, research suggests
BERKELEY — Older people have a hard time keeping a lid on their feelings, especially when viewing heartbreaking or disgusting scenes in movies and reality shows, psychologists have found. But they're better than their younger counterparts at seeing the positive side of a stressful situation and empathizing with the less fortunate, according to research from the University of California, Berkeley.

Sticking to dietary recommendations could save 33,000 lives a year
Science | Health 16 Dec 10 If everyone in the UK ate their 'five a day' and kept to recommended levels of salt and unhealthy fats, 33,000 deaths could be prevented or delayed every year, an Oxford University study has found. The research, co-funded by the British Heart Foundation (BHF), highlights the difference getting your five a day could make to the nation's health.

Cancer patients five times more likely to develop listeria
University of Manchester and Health Protection Agency researchers have shown that cancer patients have a five-fold increased risk of developing listeria than people with other underlying conditions. The study, published in the journal Emerging Infectious Diseases today (Wednesday), also showed that those with cancers of the blood have the greatest risk .

Garlic could protect against hip osteoarthritis
Researchers at King's College London and the University of East Anglia have discovered that women who consume a diet high in allium vegetables, such as garlic, onions and leeks, have lower levels of hip osteoarthritis. The findings, published in the BMC Musculoskeletal Disorders journal, not only highlight the possible effects of diet in protecting against osteoarthritis, but also show the potential for using compounds found in garlic to develop treatments for the condition.

Zebrafish ’window on cancer’ shows birth of tumour - and body’s response
Scientists using translucent zebrafish as a "window on cancer” have been able to see in real time how tumour cells are born – and immediately attract cells from the immune system. This inflammatory response seems to both attack and aid the cancer cells and the balance between the two provides a new therapeutic target for cancer researchers.
