Frugal microbes reduce the cost of proteins

Bacteria tend to be more frugal when constructing proteins for use outside of the cell versus internally, saving their energy for synthesizing compounds that can be recycled, according to research published in the current issue of the online journal mBio.

Helping corn-based plastics take more heat

A team of scientists from USDA and a cooperating company are working to make corn-derived plastics more heat tolerant -- research that may broaden the range of applications for which these plastics could be used as an alternative to petroleum-based plastics

Infant's gaze may be an early, but subtle, marker for autism risk

Kennedy Krieger Institute announced today new study results showing an early marker for later communication and social delays in infants at a higher-risk for autism may be infrequent gazing at other people when unprompted. Published in the September issue of the Journal of Child Psychology and Psychiatry, the study also found that six-month-old high-risk infants demonstrated the same level of...

Keeping faith -- schools must balance ethos with equality

Faith based schools are on the rise in the UK, apparently boosting educational standards. But are religious values at odds with legislation on equality? Research that appears today in the journal Education Management Administration and Leadership published by SAGE shows what happens when school values and those of the state diverge, with unfortunate consequences for gay students and staff.

NIST researchers create 'quantum cats' made of light

Researchers at the National Institute of Standards and Technology have created "quantum cats" made of photons (particles of light), boosting prospects for manipulating light in new ways to enhance precision measurements as well as computing and communications based on quantum physics.

Problem of fake medicines in developing countries could be solved

Counterfeiting of drugs is a huge industry with an annual turnover of more than SEK 500 billion. In Africa the situation is extremely serious. Half of the malaria medication sold there could be ineffective or even harmful. Researchers from Lund and the UK have now developed a technique that could resolve the situation.

Sensitivity to alcohol odors may indicate a genetic predisposition to alcohol dependence

Single nucleotide polymorphisms (SNPs) are DNA sequence variations that occur when a single nucleotide in the genome sequence is altered. Prior research suggested an association between SNPs in a gene that encodes aspects of the brain's gamma-amino butyric acid (GABA)-A receptors (the GABRA2 gene) and alcohol dependence. A study of responses to the aromas of alcoholic drinks according to...

Ten minutes could prevent one-third of road deaths

Spanish researchers have calculated the probability of dying in road accidents on the basis of the time taken for the emergency services to arrive. Their conclusions are clear - reducing the time between an accident taking place and the arrival of the emergency services from 25 to 15 minutes would cut the risk of death by one-third.

Text messages reveal the emotional timeline of September 11, 2001

The terrorist attacks of September 11, 2001 have been called the defining moment of our time. Thousands of people died and the attacks had huge individual and collective consequences, including two wars. But less is known about the immediate emotional reactions to the attacks. For a new study published in Psychological Science, a journal of the Association for Psychological Science, researchers...

The superwind galaxy NGC 4666 (w/ Video)

(PhysOrg.com) -- The galaxy NGC 4666 takes pride of place at the centre of this new image, made in visible light with the Wide Field Imager on the MPG/ESO 2.2-meter telescope at the La Silla Observatory in Chile. NGC 4666 is a remarkable galaxy with very vigorous star formation and an unusual "superwind" of out-flowing gas. It had previously been observed in X-rays by the ESA XMM-Newton space...

Violence in inner city neighborhoods contributes to trouble with asthma

Patients with asthma who are exposed to violence in their community are at an increased risk for an asthma-related hospitalization and emergency room visits for asthma or any cause, according to new research from the University Of Pennsylvania School of Medicine. Exposure to community violence has been linked to more symptoms in pediatric asthma patients; however the new research adds to this...

New perspectives and guidance for managing white pine blister rust

The August 2010 journal, Forest Pathology, provides a synthesis of knowledge on C. ribicola, identifies policy and management actions to mitigate disease impacts, and reviews future issues facing white pine management such as climate change and new pathogen introductions. Through this comprehensive and scholarly review of the literature, Shaw, Geils, and thirty-three contributing authors provide a...

New studies explain how cancer cells 'eat us alive'

Four key studies now propose a new theory about how cancer cells grow and survive, allowing researchers to design better diagnostics and therapies to target high-risk cancer patients. These studies were conducted by a large team of researchers at Thomas Jefferson University`s Kimmel Cancer Center.

Panel: India must secure elephant reserves

(AP) -- India should protect its elephant population by securing its wildlife reserves, curbing poaching and restricting development in the corridors they use to travel between forested areas, a panel recommended.

Study finds therapeutic targets for rare cancer in children

The first study of Ewing's sarcoma that screened hundreds of genes based on how they affect cell growth has identified two potential anti-cancer drug targets, according to a scientific paper by the Translational Genomics Research Institute (TGen) published this month in the journal Molecular Cancer.
