Scripps-developed Landers Provide New View of Ocean Floor
One of the challenges James Cameron faces in exploring the Mariana Trench is that no light is able to penetrate its extreme depths. That's where the engineering know-how of Kevin Hardy and other Scripps researchers comes into play. Hardy, a Scripps research engineer, has developed telephone-booth-size landers that are dropped to the seafloor.

Fibre protects against cardiovascular disease – especially in women
Foods high in fibre provide good protection against cardiovascular disease, and the effect is particularly marked in women. This is shown in a new study from Lund University in Sweden. The study, which was recently published in the scientific journal PLOS One, involved the study of the eating habits of over 20 000 residents of the Swedish city of Malmö, with a focus on the risk of cardiovascular disease.

How common is off-label drug prescription?
McGill team examines the practice of prescribing medications for indications that have not received regulatory approval from Health Canada A new McGill University study evaluating off-label prescribing of medications by primary care physicians in Quebec suggests the practice is common, although it varies by medication, patient and physician characteristics.

Pain could be a good thing for heart attack patients
Pain could be a good thing for heart attack patients
Feeling the pain of a heart attack could actually help the heart minimise damage, say academics in the University of Bristol's School of Clinical Sciences. The study, co-funded by the British Heart Foundation (BHF) and the European Union, showed that during a heart attack - when a blood clot blocks an artery serving the heart with oxygen - pain signals from cardiac nerves may help attract stem cells to the site of the blockage to repair some of the damage.

Discovery of genes underlying fracture susceptibility and osteoporosis
According to a study published , variants in 56 regions of the genome have been discovered to influence the Bone Mineral Density (BMD) of individuals. Fourteen of these variants were also found to increase the risk of bone fracture. Three researchers at Umeå University are involved in this study. Osteoporosis is a frequent and devastating age-related disease: 50% of subjects that fracture their hip after age 80 years die within 12 months after the event.

International team uncovers new genes that shape brain size, intelligence
UCLA-launched partnership identifies genes that boost or lessen risk of brain atrophy, mental illness, Alzheimer's disease In the world's largest brain study to date, a team of more than 200 scientists from 100 institutions worldwide collaborated to map the human genes that boost or sabotage the brain's resistance to a variety of mental illnesses and Alzheimer's disease.

Scans could aid delivery decisions
Scientists are using MRI scans to see if they can determine when best to deliver babies that are not growing as fast as they should in the womb. The University study aims to see if changes to the placenta can indicate when babies that are not growing as fast as they should need to be delivered. These babies should be delivered to improve their survival rates.

Human cell shut down debate resolved
University of Liverpool researchers have resolved the debate over the mechanisms involved in the shut-down process during cell division in the body. Research findings, published in the journal PNAS , may contribute to future studies on how scientists could manipulate this shut-down process to ensure that viruses and other pathogens do not enter the cells of the body and cause harm.

Depressed dads more negative in talking to their babies
Depressed dads more negative in talking to their babies
Dads with 'postnatal' depression are more likely to fix on negatives and be more critical of themselves when talking to their new babies. The study by Oxford University researchers is the first to look at the speech of new fathers with depression in their early interactions with their babies.

Engineered stem cells seek out and kill HIV in living organisms
Expanding on previous research providing proof-of-principal that human stem cells can be genetically engineered into HIV-fighting cells, a team of UCLA researchers have now demonstrated that these cells can actually attack HIV-infected cells in a living organism.

Wiring the brain
Wiring the brain
Scientists have created a simple new model of the human brain which reproduces the statistics of its complex network organization. Our model hints at possible mechanisms behind schizophrenia, which will be interesting to investigate further." —Dr Petra Vertes Researchers at the University of Cambridge have developed a simple mathematical model of the brain which provides a remarkably complete statistical account of the complex web of connections between various brain regions.

Cells Distinguish Between Disease-Causing and Innocuous Invaders
Green fluorescent proteins signify the expression of immune genes in the roundworm's intestine. Credit: Troemel Lab, UC San Diego The specific mechanisms by which humans and other animals are able to discriminate between disease-causing microbes and innocuous ones in order to rapidly respond to infections have long been a mystery to scientists.

Early milk feeds best for vulnerable premature babies
The way premature babies are fed in hospitals could change following the results of an Oxford University-led study. Babies who are born premature and 'growth-restricted' would generally benefit from starting milk feeds within the first 24-48 hours after birth, the study found. High-risk premature babies are vulnerable to severe bowel problems, which has led previously to a tendency to delay the start of milk feeds.

Sensing when the brain is under pressure
New monitoring strategy forgoes surgery, could help doctors treat patients with head injuries. Brain tumors and head trauma, including concussions, can elevate pressure inside the skull, potentially crushing brain tissue or cutting off the brain's blood supply. Monitoring pressure in the brains of such patients could help doctors determine the best treatment, but the procedure is so invasive - it requires drilling a hole through the skull - that it is done only in the most severely injured patients.

Siblings of stroke patients more likely to have a stroke themselves
Siblings of stroke patients more likely to have a stroke themselves
New findings from Karolinska Institutet show that individuals with a sibling who has had a stroke have an increased risk of having one themselves  and often around the same age as their brother or sister. According to the researchers, this new knowledge further emphasizes the importance of health professionals paying attention to their patients family history to prevent stroke.

Autism by the numbers: Yale researchers examine impact of new diagnostic criteria
Getting an autism diagnosis could be more difficult in 2013 when a revised diagnostic definition goes into effect. The proposed changes may affect the proportion of individuals who qualify for a diagnosis of autism spectrum disorder, according to a study by Yale Child Study Center researchers published in the April issue of the Journal of the American Academy of Child & Adolescent Psychiatry.
