Blueberries' health benefits better than many perceive Posted: 17 Jun 2016 09:07 AM PDT Consumers know some of the benefits blueberries provide, but they're less aware of the advantages of reverting aging, improving vision and memory, a new study shows. Researchers surveyed more than 2,000 people in 31 states – mostly on the East Coast and in the Midwest – to see what they know about the health benefits of blueberries.

A deadly delivery for triple-negative breast cancer tumors Posted: 17 Jun 2016 08:40 AM PDT Zinc oxide (ZnO) nanoparticles may help destroy difficult-to-treat triple-negative breast cancer tumors.

The dopamine advantage Posted: 17 Jun 2016 08:38 AM PDT The junctions between nerve cells responsible for releasing and receiving dopamine in the brain are a surprising mismatch that gives this chemical a strong competitive advantage, report researchers.

Potential drug target identified for Zika, similar viruses Posted: 17 Jun 2016 08:37 AM PDT A single gene pathway that is vital for Zika and other flaviviruses to spread infection between cells has now been identified by researchers. Further, they showed that shutting down a single gene in this pathway -- in both human and insect cells -- does not negatively affect the cells themselves and renders flaviviruses unable to leave the infected cell, curbing the spread of infection.

Fetal BPA exposure in mice linked to estrogen-related diseases after adolescence Posted: 17 Jun 2016 08:36 AM PDT The genome is permanently altered in the uterus of mice that had been exposed to BPA during their fetal development, new research indicates.

Exercise may have therapeutic potential for expediting muscle repair in older populations Posted: 17 Jun 2016 08:36 AM PDT Here's another reason why you should hit the gym regularly as you grow older: a new report shows that regular exercise plays a critical role in helping muscles repair themselves as quickly as possible after injury. After only eight weeks of exercise, old mice experienced faster muscle repair and regained more muscle mass than those of the same age that had not exercised.

New imaging method reveals nanoscale details about DNA Posted: 17 Jun 2016 08:34 AM PDT A new enhanced DNA imaging technique has been developed that can probe the structure of individual DNA strands at the nanoscale. Since DNA is at the root of many disease processes, the technique could help scientists gain important insights into what goes wrong when DNA becomes damaged or when other cellular processes affect gene expression.

Smoking can hamper common treatment for breast cancer Posted: 17 Jun 2016 07:50 AM PDT We know that individuals who smoke take major health risks. Now a new research study shows that common treatment for breast cancer works less well in patients who smoke, compared to non-smokers.

Scientists discover mechanism of thalidomide Posted: 17 Jun 2016 07:49 AM PDT In the 1950s, thalidomide (Contergan) was prescribed as a sedative drug to pregnant women, resulting in a great number of infants with serious malformations. Up to now, the reasons for these disastrous birth defects have remained unclear. Researchers have now at last identified the molecular mechanism of thalidomide. Their findings are highly relevant to current cancer therapies, as related substances are essential components of modern cancer treatment regimens.

Multicolor super resolution imaging Posted: 17 Jun 2016 07:49 AM PDT Researchers have developed a new method, using super-resolution microscopy, to determine the length of stretched proteins in living cells, and monitor the dynamic binding of proteins, at sub-second timescales.

PI3K protein: Potential new therapeutic target in pancreatic neuroendocrine tumors Posted: 17 Jun 2016 07:49 AM PDT Researchers have demonstrated that selective inactivation of the p110&alpha, PI3K isoform is sufficient to block tumor progression and metastasis in a mice model of PanNETs

X-ray-free electron laser reveals radiosensitizing effects at molecular level Posted: 17 Jun 2016 07:49 AM PDT Researchers shed light on the molecular mechanisms behind radiation-based cancer therapies, through new study.

New research paves way for improved individual treatment of patients with cancer Posted: 17 Jun 2016 07:49 AM PDT A new study has found new molecular sub-groups in early stages of bladder cancer. This improves the understanding of why some tumors develop aggressively and this discovery may lead to optimized treatment.

New mechanism activates the immune system against tumor cells Posted: 17 Jun 2016 07:49 AM PDT It is currently one challenge in cancer research to activate the body's natural defenses to eliminate tumor cells. A research team has now discovered with her team a surprising new function for the signalling molecule STAT1 in immune cells. This previously unknown feature could pave the way to a new therapeutic approach to immunological cancer therapy.

How your parenting style affects your child's future Posted: 17 Jun 2016 05:25 AM PDT Scientists have released survey results showing that children who receive positive attention and care from their parents tend to have high incomes, high happiness levels, academic success, and a strong sense of morality.

Cholera vaccine study in Haiti suggests problems with current booster regimen Posted: 16 Jun 2016 12:07 PM PDT Cholera outbreaks are on the rise. To prevent and control them, three oral cholera vaccines are currently approved by WHO. A study examining the immune response to one of them in Haitian adults finds that while the first vaccine round elicits a strong cholera-specific response in the mucosa (the first point of contact with the cholera pathogen), the booster dose after 2 weeks does not appear to stimulate the immune system further.

Mosquito saliva increases disease severity following dengue virus infection Posted: 16 Jun 2016 12:07 PM PDT Insects transmit diseases when, probing for blood vessels, they inject saliva together with viral, bacterial, or parasitic pathogens into the skin of mammalian hosts. A study in mice suggests a critical role of mosquito saliva in the outcome of dengue virus infection.

Genetic mutation causes ataxia in humans, dogs Posted: 16 Jun 2016 11:07 AM PDT Cerebellar ataxia is a condition of the cerebellum that causes an inability to coordinate muscle movements. A new study describes a new genetic mutation as an additional cause of ataxia in humans and mice. The mutation, in the gene CAPN1, affects the function of the enzyme calpain-1 and causes abnormal brain development. The same genetic mutation is also associated with ataxia in Parson Russell terrier dogs.
