New sugar a treat for diabetes treatment
New sugar a treat for diabetes treatment
Researchers from The Australian National University have discovered a new treatment for Type-1 diabetes - an autoimmune disease which currently affects some 130,000 Australians. Charmaine Simeonovic and Professor Christopher Parish from The John Curtin School of Medical Research have identified a previously unknown process which causes destruction of the insulin-producing beta cells in the pancreas.

Statins may reduce mortality in influenza patients, team finds
The two most common weapons to fight influenza are an annual immunization and the use of antiviral drugs. A team of investigators has found that statins - a drug widely used to lower cholesterol - may offer additional benefits that complement these approaches and reduces mortality among patients with influenza.

Lower classes quicker to show compassion in the face of suffering
Emotional differences between the rich and poor, as depicted in such Charles Dickens classics as "A Christmas Carol" and "A Tale of Two Cities," may have a scientific basis. Researchers at the University of California, Berkeley, have found that people in the lower socio-economic classes are more physiologically attuned to suffering, and quicker to express compassion than their more affluent counterparts.

Starving cancer
Starving cancer
A research group has developed a new strategy to fight cancer. Blood vessels in the environment of tumours are killed with a new molecule which leads to the "starvation" of the tumour. Compared to currently applied treatments, this new strategy has a series of advantages. Modern cancer therapeutics produced by biotechnological methods, often are based on antibodies.

Researchers Create Living ’Neon Signs’ Composed of Millions of Glowing Bacteria
In an example of life imitating art, biologists and bioengineers at UC San Diego have created a living neon sign composed of millions of bacterial cells that periodically fluoresce in unison like blinking light bulbs. Their achievement, detailed in this week's advance online issue of the journal Nature, involved attaching a fluorescent protein to the biological clocks of the bacteria, synchronizing the clocks of the thousands of bacteria within a colony, then synchronizing thousands of the blinking bacterial colonies to glow on and off in unison.

Penicillin study
Penicillin doses for children should be reviewed, say experts A team of scientists and clinicians, led by researchers at King's College London and St George's, University of London, are calling for a review of penicillin dosing guidelines for children, that have remained unchanged for nearly 50 years.

Targeting protein critical to cell division stops cancer cells from proliferating and kills them
Suppressing a newly identified protein involved in regulating cell division could be a novel strategy for fighting certain cancers because it stops the malignant cells from dividing and causes them to die quickly, according to a study by researchers at UCLA's Jonsson Comprehensive Cancer Center. During the five-year study, designed to seek new targets for anti-cancer therapies, researchers discovered that depleting the protein, called STARD9, also helped the commonly used chemotherapy drug Taxol work more effectively against certain cancers.

Superior drug combo for difficult-to-control epilepsy
A combination of two common drugs, lamotrigine and valproate, is more effective in treating difficult-to control epilepsy than other anti-epileptic regimens, according to a University of Washington report to be published online this week in Neurology, the journal of the American Academy of Neurology.

Pathogen causes speck disease in tomatoes
Researchers have discovered how the structure of a protein allows a certain bacteria to interfere with the tomato plant's immune system, causing bacterial speck disease. The work helps explain how Pseudomonas syringae, a bacterial pathogen, has evolved to cause disease and may open the door to breeding tomato varieties that are resistant to speck disease, which can prompt costly losses in tomato crops.

Human hairs help stop the bed bugs biting
Human hairs help stop the bed bugs biting Hairy humans do not let the bed bugs bite according to research at the University of Sheffield which shows how hair helps us defend against and detect bloodthirsty invaders on our bodies. Sensitive, fine hairs which cover our bodies allow us to feel parasitic insects on our skin as well as creating a natural barrier to stop them biting us.

Scanning strategy could help heart disease
Patients with life-threatening heart valve disease could be helped with alternative scanning techniques that provide greater insight into the condition. University researchers used an imaging technique that could help predict which patients will need open heart surgery to replace their heart valves.

Antimalarial drugs appear safe in early pregnancy
Antimalarial drugs appear safe in early pregnancy
Malaria in early pregnancy significantly increases the risk of miscarriage, but taking antimalarial drugs is relatively safe and reduces this risk. That's the finding of the largest ever study to assess the effects of malaria and its treatment in the first trimester of pregnancy. Despite the risks of malaria for pregnant women, there is very little published evidence on the effects of malaria and taking antimalarial drugs during the first trimester of pregnancy.

Research gives insights into rare bone disorder
New research by two University of Toronto professors and a post-doctoral fellow, in collaboration with a colleague at the Ontario Cancer Institute, explains the molecular basis for cherubism, a bone development disorder, and may lead to the development of new drugs to treat cancer. Cherubism is characterized by abnormal bone tissue in the lower part of the face.

Scientists identify gene that controls the spread of melanoma
Yale Cancer Center researchers have identified a gene in melanoma that can dramatically affect the spread of the disease. The study, published in the journal Cancer Cell, provides new insight into how melanoma metastasizes in patients with advanced disease, and which organs are most likely to be affected.

Tanning beds linked to skin cancer in young people
The first rigorous study of an increasingly common form of skin cancer in young people finds that indoor tanning significantly increases the risk. This new study by Yale Cancer Center researchers finds that people who used indoor tanning beds are at a significantly higher risk of developing basal cell carcinoma (BCC) before the age of 40 than people who never used indoor tanning beds.

DNA damage across a cellular barrier depends on barrier thickness
DNA damage across a cellular barrier depends on barrier thickness
The use of nanoparticles in medicine is ever increasing and it is important to understand the effects these particles might have on human tissues and health in general. Scientists have shown that signalling molecules that damage the DNA of cells grown underneath a barrier are transmitted only when the barrier is more than one layer thick and DNA damage and cytokine release is signalled across the barrier.

Step forward in foot-and-mouth disease understanding
Scientists have discovered a mechanism they believe may play a key role in the spread of foot-and-mouth disease in animals. Researchers at the University of Leeds have been studying an enzyme - called 3D - which plays a vital role in the replication of the virus behind the disease. They have found that this enzyme forms fibrous structures (or fibrils) during the replication process.
