Liver tells all and reveals truth about fat
Researchers from the University of Melbourne and Austin Health have come one step closer to understanding how our bodies regulate fat and weight gain. Barbara Fam from the University's Molecular Obesity Laboratory group at Austin Health with Associate Professor Sof Andrikopoulos have discovered that the liver can directly talk to the brain to control the amount of food we eat.

Fever study benefits African infants
Thousands of African children at high risk of infection for an endemic disease could soon benefit from treatment. Researchers tested hundreds of children aged between one and five in countries in sub-Saharan Africa where snail fever - also known as bilharzia or schistosomiasis - is endemic.

Changes in genetic function in the brain linked to Alzheimer’s
ANN ARBOR, Mich.-Changes in the epigenome, a structure that controls the function of genes, were found in the brains of Alzheimer's patients. These epigenetic changes can be caused by exposure to environmental toxicants or lifestyle behaviors, according to a study out of the University of Michigan School of Public Health.

Landmark breast cancer study
A new study could revolutionise the way women with breast cancer will be diagnosed and treated in the future by reclassifying the disease into 10 completely new categories based on the tumour's genetic 'fingerprint'. The study suggests that doctors could one day predict survival more accurately based on these new categories or subtypes, and better tailor treatment to the individual patient.

Pinpointing how antibiotics work
Team uncovers mechanism that produces fatal DNA damage in bacteria. Penicillin and other antibiotics have revolutionized medicine, turning once-deadly diseases into easily treatable ailments. However, while antibiotics have been in use for more than 70 years, the exact mechanism by which they kill bacteria has remained a mystery.

Researchers on the trail of possible SLE explanation
In the rheumatic disease SLE, the body is attacked by its own immune system, but until now no-one has been able to explain why. Researchers at Lund University in Sweden could now be on the trail of an explanation. When the body is affected by serious infections, the immune system is activated. Some of the immune system's cells throw out a net of DNA and proteins, known as neutrophil extracellular traps (NET), to neutralise foreign bacteria and viruses.

Possible new cancer treatment identified
New research findings show how it may be possible to render cancer tumours harmless without affecting the other cells and tissues in the body. The findings apply to cancers including breast, lung and bowel cancer. The study was carried out at Lund University in Sweden. Many of the most common chemotherapy drugs used to treat cancer have serious side effects because they not only affect the cells in the cancer tumour, but also the cells in the rest of the body.

Study sparks health fears for IVF children
By Professor David Celermajer. First published in The Sydney Morning Herald. April 2012 The first IVF birth worldwide was in 1978, and so the oldest IVF children are now adults. Will they have the same health outcomes as those conceived "naturally"? IVF (In Vitro Fertilisation) has brought the miracle of childbirth to hundreds of thousands; indeed it is now estimated that one percent to three percent of all births in developed nations involve IVF.

Using maths to feed the world
In the race to breed better crops to feed the increasing world population, scientists at The University of Nottingham are using maths to find out how a vital plant hormone affects growth. Gibberellin is a hormone which plays a key part in development throughout the plant, from the root to the flowers and leaves.

Raising the pulse to beat teenage blues
A unique study to test the effectiveness of personally tailored exercise programmes on young people with depression has been launched by researchers at The University of Nottingham. The power of exercise in helping people with depression is well-documented in studies looking into adult populations but not in young people.

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.

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.
