Raimon Guitart, lecturer in Toxicology at the UAB, and Vernon Thomas, emeritus professor of the University of Guelph, analysed in detail the environmental effects of using lead ammunition in shooting sports, in an article published in the AMBIO journal. Although the number of Olympic athletes specialising in these sports is reduced, and the ammunition is recovered and recycled after the competitions, there are many amateurs who practice this sport around the world, making it almost impossible to recover the ammunition after being used. Researchers show that for these ...

Nagoya, Japan – Professor Stephan Irle of the Institute of Transformative Bio-Molecules (WPI-ITbM) at Nagoya University and co-workers at Kyoto University, Oak Ridge National Lab (ORNL), and Chinese research institutions have revealed through theoretical simulations that the molecular mechanism of carbon nanotube (CNT) growth and hydrocarbon combustion actually share many similarities. In studies using acetylene molecules (ethyne; C2H2, a molecule containing a triple bond between two carbon atoms) as feedstock, the ethynyl radical (C2H), a highly reactive molecular intermediate ...

An educational intervention program for children between kindergarten and 10th grade, known as Fast Track, reduces aggressive behavior later in life, according to research published in Psychological Science, a journal of the Association for Psychological Science. The research, led by psychological scientist Justin Carré of Nipissing University in Ontario, Canada, indicates that dampened testosterone levels in response to social threats may account for the intervention's success in reducing aggression. The Fast Track intervention program teaches children social cognitive ...

CHAMPAIGN, Ill. — Researchers report they can generate human motor neurons from stem cells much more quickly and efficiently than previous methods allowed. The finding, described in Nature Communications, will aid efforts to model human motor neuron development, and to understand and treat spinal cord injuries and motor neuron diseases such as amyotrophic lateral sclerosis (ALS). The new method involves adding critical signaling molecules to precursor cells a few days earlier than previous methods specified. This increases the proportion of healthy motor neurons derived ...

This news release is available in German. Networked nerve cells are the control center of organisms. In a nematode, 300 nerve cells are sufficient to initiate complex behavior. To understand the properties of the networks, re-searchers switch cells on and off with light and observe the resulting behavior of the organism. In the Science journal, sci-entists now present a protein that facilitates the control of nerve cells by light. It might be used as a basis of studies of diseases of the nervous system. DOI: 10.1126/science.1249375 To switch a nerve cell with light, ...

People who are materialistic are more likely to be depressed and unsatisfied, in part because they find it harder to be grateful for what they have, according to a study by Baylor researchers. The study — "Why are materialists less happy? The role of gratitude and need satisfaction in the relationship between materialism and life satisfaction" — appears in the journal Personality and Individual Differences. "Gratitude is a positive mood. It's about other people," said study lead author Jo-Ann Tsang, Ph.D., associate professor of psychology and neuroscience in Baylor's ...

PORTLAND, Ore. — Medical researchers often presented the findings of their clinical trials in a different way on a federal government website than they did in the medical journals where their studies were ultimately published, according to an Oregon Health & Science University analysis published April 1 in the Annals of Internal Medicine. Researchers' reports in peer-reviewed medical journals often were more favorable to the drug or intervention being studied than the reports on the government website — ClinicalTrials.gov — which required data for specific categories, ...

In 1990, the Jamaican iguana was removed from the list of extinct species when a small population was re-discovered on the island. Unfortunately, the species continues to be critically endangered, with only a single location left for the recovering population, now greater than 200 individuals, in a protected area called the Hellshire Hills, part of the Portland Bight Protected Area. A recent proposal by Jamaican government officials to allow extensive development in this area is causing concern among conservationists who have been working to save this species and the wealth ...

WACO, Texas (March 31, 2014) – Early strengthening activities can lead to a decrease in cardiometabolic health risks in children and adolescents, according to results of a new study by a Baylor University professor and a team of researchers. Until recently, treatment for adolescent obesity and associated health problems has focused mostly on diet modifications and aerobic exercise such as walking or swimming. But a recent research study appearing this month in Pediatrics by Paul M. Gordon, Ph.D., professor and chair of health, human performance and recreation department ...

Conventional wisdom and scientific arguments have claimed that societies with more men than women, such as China, will become more violent, but a University of California, Davis, study has found that a male-biased sex ratio does not lead to more crime. Rates of rape, sexual assault and homicide are actually lower in societies with more men than women, the study found. And, evolutionary theories predicting that when males outnumber females, males will compete vigorously for the limited number of mates don't bear out. The study, "Too many men: the violence problem?" is ...

Does the widespread and still proliferating use of antimicrobial household products cause more harm than good to consumers and the environment? Evidence compiled in a new feature article published in the journal Environmental Science & Technology by Arizona State University professor Rolf Halden shows that decades of widespread use of antimicrobials has left consumers with no measurable benefits. Worse yet, lax regulation has caused widespread contamination of the environment, wildlife and human populations with compounds that appear more toxic than safe, according to ...

Hamilton, ON (April 1, 2014) Researchers at McMaster University have discovered a key molecule that could lead to new therapies for people with celiac disease, an often painful and currently untreatable autoimmune disorder. Celiac disease is a food sensitivity to dietary gluten contained in cereals. In people who are genetically predisposed, gluten containing food will trigger an immune response that leads to destruction of the intestinal lining, abdominal pain, changes in bowel habits, malnutrition and many other symptoms that include anemia, and neurological problems. ...

OTTAWA, Canada, April 1, 2014 — Clinical investigators at the Children's Hospital of Eastern Ontario (CHEO) have developed a new screening tool to help diagnose obstructive sleep apnea in children. Their findings are published in Pediatric Pulmonology. Evidence suggests that adults with a large neck circumference are more likely to develop obstructive sleep apnea (OSA), especially males. As neck circumference varies by age and sex, there have been no reference ranges to diagnose pediatric OSA up until now. The new evidence-based diagnostic tool includes reference ranges ...

The very earliest signs of a debilitating neurodegenerative disorder, in which physical symptoms are not apparent until the fifth decade of life, are detectable in individuals as young as 30 years old using a new, sophisticated type of neuroimaging, researchers at UC Davis, the University of Illinois and UCLA have found. People with the condition — fragile X-associated tremor/ataxia syndrome (FXTAS) — experience tremors, poor balance, cognitive impairments and Parkinsonism. The genetic condition results from a mutation in the fragile X mental retardation gene (FMR1). ...

PULLMAN, Wash. – Researchers in Washington State University's School of Electrical Engineering and Computer Science have developed a method to allow a computer to give advice and teach skills to another computer in a way that mimics how a real teacher and student might interact. Matthew E. Taylor, WSU's Allred Distinguished Professor in Artificial Intelligence, reports on his method in the journal Connection Science. The work was funded in part by the National Science Foundation (NSF). Researchers had the agents – as the virtual robots are called – act like true student ...

Researchers in China, [J. Appl. Cryst. (2014). 47, 527-531] have found a convenient way to selectively prepare germanium sulfide nanostructures, including nanosheets and nanowires, that are more active than their bulk counterparts and could open the way to lower cost and safer optoelectronics, solar energy conversion and faster computer circuitry. Germanium monosulfide, GeS, is emerging as one of the most important "IV–VI" semiconductor materials with potential in opto-electronics applications for telecommunications and computing, and as an absorber of light for use ...

A new discovery suggests it could one day be possible to chemically reprogram and repair damaged nerves after spinal cord injury or brain trauma. Researchers from Imperial College London and the Hertie Institute, University of Tuebingen have identified a possible mechanism for re-growing damaged nerve fibres in the central nervous system (CNS). This damage is currently irreparable, often leaving those who suffer spinal cord injury, stroke or brain trauma with serious impairments like loss of sensation and permanent paralysis. Published in Nature Communications today, ...

Charlottesville, VA (April 1, 2014). Researchers from Syracuse, New York, report a new, highly accurate, neuromonitoring method that can be used during thoracic spine surgery to prevent malpositioning of pedicle screws such that they enter the spinal canal and possibly cause postoperative neurological impairment. Findings of this prospective, blinded, and randomized study are reported and discussed in two companion papers published today online, ahead of print, in the Journal of Neurosurgery: Spine, specifically "Neuromonitoring with pulse-train stimulation for implantation ...

Child support in Tennessee paternity actions Article provided by Autry L. Jones, Attorney at Law Visit us at http://www.autryjones.com Tennessee law recognizes that both parents have legal duties to financially support their child, so when two parents do not live together, the law allows a Tennessee court to order child support. Child support arrangements usually involve one parent -- the one with whom the child does not live (or lives less) --paying money monthly to the custodial parent to help with the child's living expenses. While people think of child support ...
