LIVERMORE, Calif. -- Large-scale storage of low-pressure, gaseous hydrogen in salt caverns and other underground sites for transportation fuel and grid-scale energy applications offers several advantages over above-ground storage, says a recent Sandia National Laboratories study sponsored by the Department of Energy's Fuel Cell Technologies Office. Geologic storage of hydrogen gas could make it possible to produce and distribute large quantities of hydrogen fuel for the growing fuel cell electric vehicle market, the researchers concluded. Geologic storage solutions ...

Neuro-rehabilitation (physical therapy, occupational therapy, etc.) helps hemaparetic stroke patients confronted with loss of motor skills on one side of their body, to recover some of their motor functions after a cerebrovascular accident. One of the most promising tracks in neuro-rehabilitation consists in amplifying the motor learning ability after a stroke, in other words how to learn (again) how to make movements with the parts of the human body impacted after a stroke. Pilot studies have shown at this matter that tDCS (transcranial direct current stimulation) - ...

Nidelric pugio fossil dates to half a billion years ago and teaches us about the diversity of life in Earth's ancient seas In life the animal was a 'balloon' shape and was covered in spines, but the squashed fossil resembles a bird's nest Named in honour of Professor Richard Aldridge from the University of Leicester A rare 520 million year old fossil shaped like a 'squashed bird's nest' that will help to shed new light on life within Earth's ancient seas has been discovered in China by an international research team - and will honour the memory of a University of ...

Montreal, Canada, November x, 2014 - Angiochem, a clinical stage biotechnology company creating and developing drugs that cross the blood-brain barrier, today announced the publication in Molecular Cancer Therapeutics demonstrating that ANG4043, a peptide-monoclonal antibody (mAb) conjugate, entered the brain at therapeutic concentrations, resulting in significantly prolonged survival in mice. The antibody is directed against HER2, which is the protein targeted by Herceptin®. Because the mAb is conjugated to Angiopep-2, it is recognized by the LRP1 receptor and takes ...

Phoenix, AZ (December 9th, 2014) - Healthy, elderly research participants who report being more sleepy and less rested have higher levels of amyloid deposition in regions of the brain that are affected in Alzheimer's disease, according to a report presented today at the American College of Neuropsychopharmacology annual meeting in Phoenix (Arizona). If sleep disturbance is a cause of amyloid accumulation, it may be an early target for intervention to prevent the progression of cognitive deficits in late life. Numerous studies have shown the importance of sleep and the ...

Phoenix, AZ (December 9th, 2014) - Abnormalities in the prefrontal cortex and related brain areas are observed in adolescents who have attempted suicide, according to a report today at the American College of Neuropsychopharmacology annual meeting in Phoenix Arizona. The study suggests that deficits in frontal systems may be associated with risk for suicide attempts in youths with mood disorders. Most suicide attempts occur in the context of mood disorders, including bipolar disorder and major depressive disorder. Bipolar disorder has a prevalence of 3-4% in the U.S. population, ...

A multicenter phase 1 trial of the immune checkpoint blocker ipilimumab found clinical benefit in nearly half of blood cancer patients who had relapsed following allogeneic stem cell transplantation, according to investigators from Dana-Farber Cancer Institute, who developed and lead the study. The study reported at the American Society of Hematology annual meeting is the first in which ipilimumab was given in multiple doses over an extended time period, the researchers said. At a median follow-up time of six months, "We have seen less toxicity than expected and a strong ...

Opposing views on the potential impact of electronic cigarettes on public health are published in the open access journal BMC Medicine. The commentaries, by two experts, differ in their views on the topic but are united in their call for a rational discussion based on evidence. The authors examine the WHO's recommendations earlier this year. One recommendation was that smokers should not use e-cigarettes and has now been withdrawn, and the other is that policymakers should implement their strict regulation, which is still in force. In one of the commentaries, Peter ...

Sophia Antipolis, 09 December 2014: Heart disease patients have been advised to avoid being outside during rush hour traffic in a paper published today in European Heart Journal.1 The position paper on air pollution and cardiovascular disease was written by experts from the European Society of Cardiology and also recommends decreasing the use of fossil fuels. Professor Robert F. Storey, corresponding author of the paper, said: "More than 3 million deaths worldwide are caused by air pollution each year. Air pollution ranks ninth among the modifiable disease risk factors, ...

There is no need to spray insecticide on walls for malaria control when people sleep under treated bed nets, according to new research. Use of insecticide sprayed on internal walls, when combined with insecticide-treated bed nets in homes, does not protect children from malaria any more effectively than using just insecticide-treated bed nets, the research led by Durham University and the Medical Research Council's Unit in The Gambia found. The researchers said this was important as insecticide-treated nets and insecticide sprayed on walls are commonly used for controlling ...

The system that allows patients rapid access to expensive new treatments lacks transparency and penalises small and low-income countries unable to negotiate lower prices with pharmaceutical manufacturers. Writing in the Journal of the Royal Society of Medicine, the authors of an essay on market-access agreements for anti-cancer drugs, say that while the underlying strategy is to help reduce the likelihood of health systems paying for treatments that turn out not to be cost-effective, the agreements can also be seen as an opportunistic way for pharmaceutical manufacturers ...

Donald Trump's ego may be the size of his financial empire, but that doesn't mean he's the picture of mental health. The same can be said about the self-esteem of people who are living from paycheck to paycheck, or unemployed. New research from the University of California, Berkeley, underscores this mind-wallet connection. UC Berkeley researchers have linked inflated or deflated feelings of self-worth to such afflictions as bipolar disorder, narcissistic personality disorder, anxiety and depression, providing yet more evidence that the widening gulf between rich and ...

The combined use of spraying insecticide inside homes and insecticide-treated bed nets is no better at protecting children against malaria than using bed nets alone, a study in The Gambia suggests. The findings, published in The Lancet, should encourage donors to invest their limited resources in additional bed nets, the more cost-effective solution to tackling malaria*. Lead author Professor Steve Lindsay, a disease ecologist at Durham University in the UK explains, "Our findings do not support any universal recommendation for indoor residual spraying as an addition ...

The mass die-off of nerve cells in the brains of people with Alzheimer's disease may largely occur because an entirely different class of brain cells, called microglia, begin to fall down on the job, according to a new study by researchers at the Stanford University School of Medicine. The researchers found that, in mice, blocking the action of a single molecule on the surface of microglia restored the cells' ability to get the job done -- and reversed memory loss and myriad other Alzheimer's-like features in the animals. The study, to be published online Dec. 8 in ...

1. Breast density notification laws substantially increase costs yet save few lives Laws requiring women to be notified of their breast density so that they may discuss supplemental screening options, including ultrasound, with their health care providers would substantially increase costs and save relatively few lives, according to an article published in Annals of Internal Medicine. More than 40 percent of women between the ages of 40 and 74 have dense breast tissue, which puts them at increased risk for breast cancer and affects how well a mammogram can detect abnormalities. ...

In the most comprehensive look yet at the safety of abortion, researchers at UC San Francisco have concluded that major complications are rare, occurring less than a quarter of a percent of the time, about the same frequency as colonoscopies. The study, published online on Monday, Dec. 8, 2014, in Obstetrics & Gynecology, analyzed data from more than 50,000 women enrolled in the Medi-Cal fee-for-service program who obtained abortions from 2009 to 2010, and looked for complications that occurred within six weeks of the procedure. The rate is similar to what has been ...

Glucose is a component of carbohydrates, and the main energy source used by brain cells. By studying rats, a team at Imperial College London identified a mechanism that appears to sense how much glucose is reaching the brain, and prompts animals to seek more if it detects a shortfall. The researchers believe it may play a role in driving our preference for sweet and starchy foods. The study, funded by the Biotechnology and Biological Sciences Research Council, is published in the Journal of Clinical Investigation. Dr James Gardiner, from the Department of Medicine, ...

Patients with plasma cell dyscrasis have high amounts of an abnormal immunoglobulin, called a paraprotein, in their blood. While many patients have no outward symptoms, paraproteins can impair immune function, thicken blood, and damage organs. Plasma cell dyscrasis may be inherited, but risk factors for this disease are poorly understood. A new study in the Journal of Clinical Investigation suggests that the presence of a modified host protein is associated with plasma cell dyscrasis risk. Michael Pfreundschuh and colleagues evaluated paraproteins in blood from patients ...

Glucose is the primary fuel for the brain. Therefore, it has been proposed that the brain must sense glucose and promote eating behaviors when levels are low. A new study in the Journal of Clinical Investigation reveals that activation of an enzyme, glucokinase, in a region of the hypothalamus called the arcuate nucleus specifically increases glucose uptake. Steve Bloom and colleagues at Imperial College London determined that glucokinase levels in the arcuate nucleus are dramatically increased in fasted rats. In their rodent models, activation of glucokinase in the acruate ...

Saturn's largest moon, Titan, is one of the few solar system bodies - and the only planetary moon - known to have fields of wind-blown dunes on its surface. (The others are Venus, Earth and Mars.) New research, using experimental results from the high-pressure wind tunnel at Arizona State University's Planetary Aeolian Laboratory, has found that previous estimates of how fast winds need to blow to move sand-size particles around on Titan are about 40 percent too low. A team of scientists led by Devon Burr of the University of Tennessee, Knoxville reported the findings ...

An enormous spectrum of light streams from the sun. We're most familiar with the conventional visible white light we see with our eyes from Earth, but that's just a fraction of what our closest star emits. NASA regularly watches the sun in numerous wavelengths because different wavelengths provide information about different temperatures and processes in space. Looking at all the wavelengths together helps to provide a complete picture of what's occurring on the sun over 92 million miles away - but no one has been able to focus on high energy X-rays from the sun until recently. In ...

COLUMBUS, Ohio - When it comes to specialized cancer surgery, it's generally true that the more experienced the surgeon, the better the outcome. The same might hold true for radiation therapy used to treat head and neck cancer, according to a new study led by researchers Evan Wuthrick, MD, assistant professor of radiation oncology at The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC - James), and Maura Gillison, MD, PhD, professor of internal medicine and epidemiology at the OSUCCC - ...

A team of researchers at Dartmouth College and University of Pittsburgh found respondents who had smoked water pipe tobacco but not smoked cigarettes were at increased risk of cigarette smoking two years later as recently published online in JAMA Pediatrics. The study followed 2,541 adolescents and young adults for two years. Samir Soneji, PhD, a tobacco regulatory control researcher at Dartmouth and lead author on the study said, "We found hookah smoking increased the probability of trying cigarette smoking over the next two years by 19%." This longitudinal study ...
