One of the most efficient means of transporting freight is by ship. However, many of the ships sailing today are powered by ageing diesel motors fitted with neither exhaust cleaning equipment nor or modern control systems. Three years ago the University of Birmingham initiated an ambitious trial, converting an old canal barge to use hydrogen fuel. The old diesel motor, drive system and fuel tank were removed and replaced with a high efficiency electric motor, a battery pack for short-term energy supply and a fuel cell with a hydrogen storage system to charge the batteries. ...

Population movements in the wake of disasters make it difficult to deliver the right amount of humanitarian aid to the right places. During the earthquake and ensuing cholera epidemic in Haiti, researchers at Karolinska Institutet, Sweden, and Columbia University, USA, developed a new method for solving this problem – they monitored the continual movements of two million anonymous mobile phones and reported directly to the humanitarian relief organisations on the ground. The method, which is now presented in the scientific journal PLoS Medicine, may have a major impact ...

Philadelphia, PA, August 31, 2011 - Does Dad's stress affect his unborn children? According to the results of a new study in Elsevier's Biological Psychiatry, it seems the answer may be "yes, but it's complicated". The risk of developing depression, which is significantly increased by exposure to chronic stress, is influenced by both environment and genetics. The interplay of these two factors is quite complex, but in fact, there is even a third factor that most of us know nothing about – epigenetics. Epigenetics is the science of changes in genetic expression that are ...

An article in the current issue of Global Change Biology Bioenergy examines the carbon sequestration potential of Miscanthus plantations on commercial farms. Researchers evaluated Miscanthus plantations in Ireland, where planting has been subsidized by the government. Carbon sequestration is expected to vary among different farming practices and soil characteristics. They found significant soil carbon sequestration under Miscanthus on both former tilled land and former grasslands after only two years of planting with little evidence that its introduction contributes to ...

Scientists have discovered a genetic cause of extreme thinness for the first time, in a study published today in the journal Nature. The research shows that people with extra copies of certain genes are much more likely to be very skinny. In one in 2000 people, part of chromosome 16 is duplicated, making men 23 times and women five times more likely to be underweight. Each person normally has a copy of each chromosome from each parent, so we have two copies of each gene. But sometimes sections of a chromosome can be duplicated or deleted, resulting in an abnormal 'dosage' ...

Washington, DC, August 31, 2011 – More than 60 percent of hospital nurses' and doctors' uniforms tested positive for potentially dangerous bacteria, according to a study published in the September issue of the American Journal of Infection Control, the official publication of APIC - the Association for Professionals in Infection Control and Epidemiology.

(Providence, R.I.) – The journal Radiology will publish in its September issue an article written by Damian E. Dupuy, M.D., director of tumor ablation at Rhode Island Hospital, supporting the use of ablation procedures for the treatment of lung cancer. The article, "Image-guided Thermal Ablation of Lung Malignancies," reviews the results of nearly 100 studies conducted between 1991 and 2011 that conclude that image-guided ablation for lung cancer is a successful alternative for patients who cannot withstand surgery due to advanced age or medical comorbidities. Percutaneous ...

As a crippling drought grips much of the Southern and Southwestern United States, the population continues to grow and water resources become scarcer. One way to address the problem is by a combination of modern engineering and ancient social principles, outlined in a new paper on rainwater harvesting that will be presented at the 2011 ASME International Mechanical Engineering Congress and Exposition. Author John Whear, biomedical engineer at the Cancer Therapy & Research Center at The University of Texas Health Science Center at San Antonio, examines how to manage rainwater ...

Thanks to advances in experimental design, physicists at the National Institute of Standards and Technology (NIST) have achieved a record-low probability of error in quantum information processing with a single quantum bit (qubit)—the first published error rate small enough to meet theoretical requirements for building viable quantum computers. A quantum computer could potentially solve certain problems that are intractable using today's technology, even supercomputers. The NIST experiment with a single beryllium ion qubit, described in a forthcoming paper,* is a milestone ...

It's not often that someone can claim that going from a positive to a negative is a step forward, but that's the case for a team of scientists from the National Institute of Standards and Technology (NIST) and private industry. In a recent paper,* the group significantly extended the reach of their novel microfluidic system for analyzing the chemical components of complex samples. The new work shows how the system, meant to analyze real-world, crude mixtures such as dirt or whole blood, can work for negatively charged components as well as it has in the past for positively ...

Much like a meteor impacting a planet, highly charged ions hit really hard and can do a lot of damage, albeit on a much smaller scale. And much like geologists determine the size and speed of the meteor by looking at the hole it left, physicists can learn a lot about a highly charged ion's energy by looking at the divots it makes in thin films. Building upon their work for which they were recently awarded a patent,* scientists at the National Institute of Standards and Technology (NIST) and Clemson University have measured the energy of highly charged ion impacts on a ...

Solar power is not all sunshine. It has a dark side—particularly in developing countries, according to a new study by a University of Tennessee, Knoxville, engineering professor. A study by Chris Cherry, assistant professor in civil and environmental engineering, found that solar power heavily reliant on lead batteries has the potential to release more than 2.4 million tons of lead pollution in China and India. Lead poisoning causes numerous adverse health effects, including damage to the central nervous system, the kidneys, the cardiovascular system, and the reproductive ...

In an effort to understand what happens in the brain when a person reads or considers such abstract ideas as love or justice, Princeton researchers have for the first time matched images of brain activity with categories of words related to the concepts a person is thinking about. The results could lead to a better understanding of how people consider meaning and context when reading or thinking. The researchers report in the journal Frontiers in Human Neuroscience that they used functional magnetic resonance imaging (fMRI) to identify areas of the brain activated when ...

With a nod to biology, scientists at the National Institute of Standards and Technology (NIST) have a new approach to the problem of safely storing hydrogen in future fuel-cell-powered cars. Their idea: molecular scale "veins" of iron permeating grains of magnesium like a network of capillaries. The iron veins may transform magnesium from a promising candidate for hydrogen storage into a real-world winner. Hydrogen has been touted as a clean and efficient alternative to gasoline, but it has one big drawback: the lack of a safe, fast way to store it onboard a vehicle. ...

Bethesda, MD—A new research report published in The FASEB Journal (https://www.fasebj.org) will help ophthalmologists and scientists better understand a rare genetic disease that causes increased susceptibility to blue light, night blindness, and decreased vision called Enhanced S-Cone Syndrome or Goldman-Favre Syndrome. In the report, scientists found that the expression of genes responsible for the healthy renewal of rods and cones in the retina was reduced and that this problem originates in the photoreceptors themselves rather than in the adjacent retinal pigment epithelial ...

A new study shows that donations collected by check boxes on state income tax forms, fees from license plates and revenue from state lottery tickets have raised millions for breast cancer research and prevention programs across the country, according to researchers at Washington University in St. Louis. "We found that revenue-generating breast cancer initiatives can be a successful strategy for states to raise funds, or 'pink ribbon dollars,' for prevention and early detection programs," says Amy A. Eyler, PhD, research associate professor at the Brown School of Social ...
