How neurons get wired Posted: 14 Aug 2013 04:22 PM PDT Scientists have discovered an unknown mechanism that establishes polarity in developing nerve cells. Understanding how nerve cells make connections is an important step in developing cures for nerve damage resulting from spinal cord injuries or neurodegenerative diseases such as Alzheimer's.

Researchers use nanoparticles to fight cancer Posted: 14 Aug 2013 04:22 PM PDT Researchers are developing a new treatment technique that uses nanoparticles to reprogram immune cells so they are able to recognize and attack cancer.

Brain scans could predict response to antipsychotic medication Posted: 14 Aug 2013 04:19 PM PDT Researchers have identified neuroimaging markers in the brain which could help predict whether people with psychosis respond to antipsychotic medications or not.

Forensic familial search methods carry risk of certain false matches Posted: 14 Aug 2013 04:19 PM PDT Forensic DNA-based familial search methods may mistakenly identify individuals in a database as siblings or parents of an unknown perpetrator, when in fact they are distant relatives, according to new research.

Facebook use predicts declines in happiness, new study finds Posted: 14 Aug 2013 04:19 PM PDT Facebook helps people feel connected, but it doesn't necessarily make them happier, a new study shows.

Potent mechanism helps viruses shut down body's defense system against infection Posted: 14 Aug 2013 04:13 PM PDT Researchers have discovered a powerful mechanism by which viruses such as influenza, West Nile and Dengue evade the body's immune response and infect humans with these potentially deadly diseases. The findings may provide scientists with an attractive target for novel antiviral therapies.

Children exposed to lead three times more likely to be suspended from school Posted: 14 Aug 2013 04:05 PM PDT Children who are exposed to lead are nearly three times more likely to be suspended from school by the 4th grade than children who are not exposed, according to a new study.

Researchers debunk myth of 'right-brained' and 'left-brained' personality traits Posted: 14 Aug 2013 04:05 PM PDT Neuroscientists now assert that there is no evidence within brain imaging that indicates some people are right-brained or left-brained. For years in popular culture, the terms left-brained and right-brained have come to refer to personality types, with an assumption that some people use the right side of their brain more, while some use the left side more. Researchers have debunked that myth through identifying specific networks in the left and right brain that process lateralized functions.

Study debunks controversial multiple sclerosis theory Posted: 14 Aug 2013 04:05 PM PDT New research found no evidence of abnormalities in the internal jugular or vertebral veins or in the deep cerebral veins of any of 100 patients with multiple sclerosis (MS) compared with 100 people who had no history of any neurological condition.

Cancer's origins revealed: Genetic imprints and signatures left by DNA-damaging processes that lead to cancer identified Posted: 14 Aug 2013 10:24 AM PDT Scientists have provided the first comprehensive genomic map of mutational processes that drive tumour development. Together, these mutational processes explain the majority of mutations found in 30 of the most common cancer types.

Targeting aggressive prostate cancer: How non-coding RNAs fuel cancer growth Posted: 14 Aug 2013 10:22 AM PDT Researchers have identified a key mechanism behind aggressive prostate cancer that spurs tumor growth and metastasis and makes cancers resistant to treatment.

Children of obese mothers at greater risk of early heart death as adults Posted: 14 Aug 2013 09:50 AM PDT Children of obese and overweight women have a higher risk of early cardiovascular death as adults, finds a new study.

A genetic answer to the Alzheimer's riddle? Posted: 14 Aug 2013 09:50 AM PDT What if we could pinpoint a hereditary cause for Alzheimer's, and intervene to reduce the risk of the disease? We may be closer to that goal, thanks to new work in Alzheimer's genetics.

Watermelon juice relieves post-exercise muscle soreness Posted: 14 Aug 2013 09:49 AM PDT Watermelon juice's reputation among athletes is getting scientific support in a new study, which found that juice from the summer favorite fruit can relieve post-exercise muscle soreness. The report attributes watermelon's effects to the amino acid L-citrulline.

Visualized heartbeat can trigger 'out-of-body experience' Posted: 14 Aug 2013 09:48 AM PDT A visual projection of human heartbeats can be used to generate an "out-of-body experience," according to new research. The findings could inform new kinds of treatment for people with self-perception disorders, including anorexia.

Two left feet? Study looks to demystify why we lose our balance Posted: 14 Aug 2013 09:47 AM PDT It's always in front of a million people and feels like eternity. You're strolling along when suddenly you've stumbled -- the brain realizes you're falling, but your muscles aren't doing anything to stop it.

How bacteria found in mouth may cause colorectal cancer Posted: 14 Aug 2013 09:43 AM PDT Gut microbes have recently been linked to colorectal cancer, but it has not been clear whether and how they might cause tumors to form in the first place. Two studies reveal how gut microbes known as fusobacteria, which are found in the mouth, stimulate bad immune responses and turn on cancer growth genes to generate colorectal tumors. The findings could lead to more effective strategies for the early diagnosis, prevention, and treatment of colorectal cancer.

Low-grade prostate cancers may not become aggressive with time -- adds support for 'watch and wait' approach Posted: 14 Aug 2013 06:56 AM PDT Prostate cancer aggressiveness may be established when the tumor is formed and not alter with time, according to a new study published.

Newly identifed molecules necessary for memory formation Posted: 14 Aug 2013 06:56 AM PDT Researchers have uncovered a cellular mechanism for memory and learning that provides one avenue for how these take place.
