93 percent of homicides of US law enforcement officers result from firearms
While occupational homicides continue to decline in the US, law enforcement remains one of the deadliest jobs in America. A new study led by researchers at the Johns Hopkins Bloomberg School of Public Health The report found documents that 93 percent of homicides of law enforcement officers between 1996 and 2010 were committed with firearms. Among those homicides, 10 percent were committed using the officer's own service weapon. The findings could help develop new procedures to reduce risk to officers.

Adult stem cells could hold key to curing Type 1 diabetes
Millions of people with Type 1 diabetes depend on daily insulin injections to survive. They would die without the shots because their immune system attacks the very insulin-producing cells it was designed to protect. Now, a University of Missouri scientist has discovered that this attack causes more damage than scientists realized. The revelation is leading to a potential cure that combines adult stem cells with a promising new drug.

Team finds gene that helps honey bees find flowers (and get back home)
Honey bees don't start out knowing how to find flowers or even how to get around outside the hive. Before they can forage, they must learn to navigate a changing landscape and orient themselves to the sun. In a new study, researchers report that a regulatory gene known to be involved in the detection of novelty in vertebrates also kicks into high gear in the brains of honey bees when they are learning how to find food and bring it home.

Carnegie Mellon neuroscientists discover new phase of synaptic development
Students preparing for final exams might want to wait before pulling an all-night cram session -- at least as far as their neurons are concerned. Carnegie Mellon University neuroscientists have discovered a new intermediate phase in neuronal development during which repeated exposure to a stimulus shrinks synapses.

Travelers play valuable role assisting crew in common medical emergencies on flights
Medical emergencies during commercial airline travel can be a frightening experience, but most situations are well-treated by other passengers and flight attendants, in collaboration with consulting physicians on the ground. A University of Pittsburgh study published today in the New England Journal of Medicine found that doctors, nurses and other medical professionals on the aircraft helped to treat sick fellow passengers in three-fourths of the emergencies studied.

New Mayo Clinic approach could lead to blood test to diagnose Alzheimer's in earliest stage
Blood offers promise as a way to detect Alzheimer's disease at its earliest onset, Mayo Clinic researchers say. They envision a test that would detect distinct metabolic signatures in blood plasma that are synonymous with the disease -- years before patients begin showing cognitive decline. Their study was recently published online in the journal PLOS ONE.

Radiotherapy remains the treatment of first choice for high-risk low-grade glioma
In a large, international, randomized trial, initial radiotherapy was compared to temozolomide chemotherapy. A statistically significant difference between the two treatment strategies was not observed for progression-free survival, although radiotherapy was numerically favored. However, molecular tumor characterization may allow the treatment approach to be personalized and one or the other treatment modality to be selected.

Are children who take Ritalin for ADHD at greater risk of future drug abuse?
Children who take medication such as Ritalin and Adderall for attention-deficit hyperactivity disorder (ADHD) are at no greater risk for later taking alcohol, marijuana, nicotine and cocaine than children with ADHD who do not take the medication, report UCLA psychologists who have conducted the most comprehensive assessment ever on this question.

Wit, grit and a supercomputer yield chemical structure of HIV capsid
Researchers report that they have determined the precise chemical structure of the HIV capsid, a protein shell that protects the virus's genetic material and is a key to its virulence. The capsid has become an attractive target for the development of new antiretroviral drugs. The report appears as the cover article in the journal Nature.

Early brain responses to words predict developmental outcomes in children with autism
The pattern of brain responses to words in 2-year-old children with autism spectrum disorder predicted the youngsters' linguistic, cognitive and adaptive skills at ages 4 and 6, according to a new study. The findings are among the first to demonstrate that a brain marker can predict future abilities in children with autism.

Gene therapy gives mice broad protection to pandemic flu strains, including 1918 flu
Researchers have developed a new gene therapy to thwart a potential influenza pandemic. They demonstrated that a single dose of an adeno-associated virus expressing a broadly neutralizing flu antibody into the noses of animal models gives them complete protection and substantial reductions in flu replication when exposed to lethal strains of H5N1 and H1N1 flu virus. These were isolated from samples associated from historic human pandemics -- the infamous 1918 flu pandemic and another from 2009.

Picking up a second language is predicted by ability to learn patterns
Some people seem to pick up a second language with relative ease, while others have a much more difficult time. Now, a new study suggests that learning to understand and read a second language may be driven, at least in part, by our ability to pick up on statistical regularities.

Preventing 'traffic jams' in brain cells
Each brain cell has an internal highway system for transporting essential materials between different parts of the cell. Understanding blockages on these highways and how traffic should flow normally in healthy cells could offer hope to people with neurodegenerative diseases. Toward that end, a research team has shown that the protein presenilin plays an important role in controlling neuronal traffic on microtubule highways, a novel function that previously was unknown.

New ruthenium complexes target cancer cells without typical side effects
Pre-clinical tests conducted at UT Arlington and published in Molecular Cancer Therapeutics found two ruthenium polypyridyl complexes, or RPCs, yielded results comparable to cisplatin against human non-small cell lung cancer cells and were generally cleared from the body unchanged, without noticeable effects on metabolism or kidney function. Healthy cells could withstand almost 10 times as much exposure to the ruthenium complexes as the cancer cells and the RPCs seemed to target cells in hypoxic states.
