Tumor-seeking salmonella treats brain tumors

Wed, 11/01/2017 - 3:29pm
Genetic tweaks to salmonella turn the bacteria into cancer-seeking missiles that produce self-destruct orders deep within tumors. Tests in rat models with extreme cases of the disease showed a remarkable 20 percent survival rate over 100 days -- roughly equivalent to 10 human years -- with the tumors going into complete remission.

A novel cancer immunotherapy shows early promise in preclinical studies

Wed, 11/01/2017 - 3:29pm
Scientists report that GARP, a TGF-beta cell surface receptor, could be a novel diagnostic marker for breast, colon, and lung cancer. An antibody-based therapy targeting GARP prevented metastasis to the lung in a mouse model of breast cancer. Targeting GARP with an antibody could represent a novel addition to established immunotherapies that 'wake up' the immune system so that it can fight cancer.

Surprise advance in the treatment of adult cancers

Wed, 11/01/2017 - 3:29pm
An epigenetic modification that might be the cause of 15% of adult cancers of the throat linked to alcohol and tobacco use was identified. This discovery was unexpected since it seemed highly improbable that this kind of alterations of the epigenome found in children could also target an epithelial tumor like throat cancer that occurs only in adults.

Updated classification system captures many more people at risk for heart attack

Wed, 11/01/2017 - 3:29pm
Experts have published a suggested new plan for a five-stage system of classifying the risk of heart attack in those with heart disease, one they say puts much-needed and long-absent focus on the risks faced by millions of Americans who pass so-called stress tests or have less obvious or earlier-stage danger signs.

Nature's weaving formula used to engineer advanced functional materials

Wed, 11/01/2017 - 3:29pm
For the first time, biomedical engineers have woven a 'smart' fabric that mimics the sophisticated and complex properties of one nature's ingenious materials, the bone tissue periosteum. Having achieved proof of concept, the researchers are now ready to produce fabric prototypes for a range of advanced functional materials that could transform the medical, safety and transport sectors.

Psychology: Playful people are at an advantage

Wed, 11/01/2017 - 3:28pm
Adults can positively utilise their inclination towards playfulness in many situations. They are good at observing, can easily see things from new perspectives, and can turn monotonous tasks into something interesting. At the same time, playfulness should not be equated with humor. Instead we need a new vocabulary to describe it, write psychologists.

Looking for life in all the right places, with the right tool

Wed, 11/01/2017 - 3:28pm
Researchers have invented a range of instruments from giant telescopes to rovers to search for life in outer space, but so far, these efforts have yielded no definitive evidence that it exists beyond Earth. Now scientists have developed a new tool that can look for signs of life with 10,000 times more sensitivity than instruments carried on previous spaceflight missions.

Testing breast milk for cannabinoids

Wed, 11/01/2017 - 3:28pm
With the legalization of medical and recreational marijuana spreading across the country, the drug's use is reportedly increasing among pregnant women. It stands to reason that many of these women will continue to use marijuana after they give birth. Now researchers have developed a new method to help determine what this means for infants' potential exposure to the active compounds in marijuana in breast milk.

First ever perched landing performed using machine learning algorithms

Wed, 11/01/2017 - 3:28pm
The very first unmanned aerial vehicle (UAV) to perform a perched landing using machine learning algorithms has been developed by researchers. The revolutionary development of a fixed wing aircraft that can land in a small or confined space has the potential to significantly impact intelligence-gathering and the delivery of aid in a humanitarian disaster.

Researchers find a potential target for anti-Alzheimer treatments

Wed, 11/01/2017 - 2:35pm
Scientists have identified a gene that may provide a new starting point for developing treatments for Alzheimer’s disease (AD). The USP9 gene has an indirect influence on the so-called tau protein, which is believed to play a significant role in the onset of Alzheimer’s disease. This discovery may open a new door to developing active ingredients to treat Alzheimer’s disease.

Conifer cones bear their ages well, and still move it

Wed, 11/01/2017 - 2:35pm
Fossil conifer cones can still move their individual seed scales after millions of years, biologists have found. The cones analyzed in a new study represent the oldest known plant structures that are still capable of movement and can also serve as a model for bioinspired technical applications with low maintenance requirements.

Remembering where to get high

Wed, 11/01/2017 - 2:35pm
Addiction-related memories are exceptionally strong and stable, suggesting that addictive drugs remodel the brain’s circuitry in a prominent and lasting way. In the past decade, researchers have used mouse models to unravel how cellular changes in the nucleus accumbens (NAc), a brain structure involved in action selection associated with arousal and reward, may contribute to addiction-related behavior. Whereas neuronal remodeling in the NAc explains a wide range of addictive behaviors, it is not required for all of them, according to a study.

'Gene-silencing' technique is a game-changer for crop protection

Wed, 11/01/2017 - 2:34pm
Ground-breaking research based on nanotechnology promises to help conquer the greatest threat to global food crops – pests and diseases in plants, report scientists who have developed a non-toxic, degradable spray which is capable of disabling specific genes in plant. ‘BioClay’ spray protects plants from disease-causing pathogens without altering their DNA, they report.

Manager, are you aware of beliefs guiding your actions?

Wed, 11/01/2017 - 2:34pm
A new study explores managers' perceptions on firm performance. According to the study, managers approach firm performance differently. One managing director emphasizes partnership with customers, where as other emphasize fine tuning in production. Various things influence managers' perceptions. For instance, different management tools like Balanced scorecard and demands from customer firms influence the perceptions.

Blood test may help predict confusion after surgery

Wed, 11/01/2017 - 2:34pm
Many people experience an extended period of confusion when they awake after surgery. This acute confusional state, called delirium, particularly affects older adults and poses an important clinical challenge as it can lead to greater postoperative complications and may extend hospitalization.
