The UK could generate almost half its energy needs from biomass sources, including household waste, agricultural residues and home-grown biofuels by 2050, new research suggests. Scientists from the Tyndall Centre for Climate Change Research at The University of Manchester found that the UK could produce up to 44% of its energy by these means without the need to import. The study, published in Energy Policy journal, highlights the country's potential abundance of biomass resources that are currently underutilised and totally overlooked by the bioenergy sector. Instead, ...

The debut of cyborgs who are part human and part machine may be a long way off, but researchers say they now may be getting closer. In a study published in ACS' journal Nano Letters, they report development of a coating that makes nanoelectronics much more stable in conditions mimicking those in the human body. The advance could also aid in the development of very small implanted medical devices for monitoring health and disease. Charles Lieber and colleagues note that nanoelectronic devices with nanowire components have unique abilities to probe and interface with living ...

This news release is available in German. Geckos outclass adhesive tapes in one respect: Even after repeated contact with dirt and dust do their feet perfectly adhere to smooth surfaces. Researchers of the KIT and the Carnegie Mellon University, Pittsburgh, have now developed the first adhesive tape that does not only adhere to a surface as reliably as the toes of a gecko, but also possesses similar self-cleaning properties. Using such a tape, food packagings or bandages might be opened and closed several times. The results are published in the "Interface" journal of ...

The chemical leak that contaminated drinking water in the Charleston, W.Va., area last month put in sharp relief the shortcomings of the policies and research that apply to thousands of chemicals in use today. An article in Chemical & Engineering News (C&EN), the weekly magazine of the American Chemical Society, delves into the details of the accident that forced 300,000 residents to live on bottled water for days. A team of C&EN reporters and editors note that the main chemical that leaked into the water supply is an obscure one called 4-methylcyclohexanemethanol, or ...

Electronics are getting smaller all the time, but there's a limit to how tiny they can get with today's materials. Researchers now say, however, that they have developed a way to shrink capacitors — key components that store energy — even further, which could accelerate the development of more compact, high-performance next-gen devices. The study appears in the journal ACS Nano. Takayoshi Sasaki and colleagues point out that many recent improvements have already downsized capacitors significantly. But current technology has almost reached its limit in terms of materials ...

Washington, DC (February 19 2014) – The lifelong debate of nature versus nurture continues—this time in what your children watch. A recent paper published in the Journal of Communication found that a specific variation of the serotonin-transporter gene was linked to children who engaged in increased viewing of violent TV and playing of violent video games. Sanne Nikkelen, Helen Vossen, and Patti Valkenburg of the University of Amsterdam's School of Communication Research, in collaboration with researchers at the Erasmus University Medical Centre in Rotterdam, analyzed ...

While taking in the scenery during long road trips, passengers also may be taking in potentially harmful ultrafine particles (UFPs) that come into the car through outdoor air vents. Closing the vents reduces UFPs, but causes exhaled carbon dioxide to build up. Now, scientists report in the ACS journal Environmental Science & Technology that installing a newly developed high-efficiency cabin air filter (HECA) could reduce UFP exposure by 93 percent and keep carbon dioxide levels low. Yifang Zhu and Eon Lee explain that most modern cars come with cabin air filters, but ...

New technology to capture the kinetic energy of our everyday movements, such as walking, and to convert it into electrical energy has come a step closer thanks to research to be published in the International Journal Biomechatronics and Biomedical Robotics. Researchers have for many years attempted to harvest energy from our everyday movements to allow us to trickle charge electronic devices while we are walking without the need for expensive and cumbersome gadgets such as solar panels or hand-cranked chargers. Lightweight devices are limited in the voltage that they ...

1. Scientists at A*STAR's Institute of Molecular and Cell Biology (IMCB) have identified the precise role of the protein, SNX27, in the pathway leading to memory and learning impairment. The study broadens the understanding of the brain's memory function and could be used to explain defects in the cognitive development of those with Down's syndrome. The newly established knowledge could potentially facilitate exploration of strategies to improve memory and learning abilities in Down's syndrome. 2. Down's syndrome is a genetic condition characterized by the presence ...

BOSTON — A new bioprinting method developed at the Wyss Institute for Biologically Inspired Engineering at Harvard University and the Harvard School of Engineering and Applied Sciences (SEAS) creates intricately patterned 3D tissue constructs with multiple types of cells and tiny blood vessels. The work represents a major step toward a longstanding goal of tissue engineers: creating human tissue constructs realistic enough to test drug safety and effectiveness. The method also represents an early but important step toward building fully functional replacements for injured ...

Feb. 19, 2014 (Toronto) - An antidepressant medication has shown potential in treating symptoms of agitation that occur with Alzheimer's disease and in alleviating caregivers' stress, according to a multi-site U.S.- Canada study. "Up to 90 per cent of people with dementia experience symptoms of agitation such as emotional distress, restlessness, aggression or irritability, which is upsetting for patients and places a huge burden on their caregivers," said Dr. Bruce G. Pollock, Vice President of Research at the Centre for Addiction and Mental Health (CAMH), who directed ...

New research from psychologists at the universities of Kent and Limerick has found that music that is felt to be 'beautiful but sad' can help people feel better when they're feeling blue. The research investigated the effects of what the researchers described as Self-Identified Sad Music (SISM) on people's moods, paying particular attention to their reasons for choosing a particular piece of music when they were experiencing sadness - and the effect it had on them. The study identified a number of motives for sad people to select a particular piece of music they perceive ...

With its narrow connection to the North Sea, strong currents, a large number of river estuaries and a bottom profile marked by ridges, basins and troughs, the Baltic represents an inland sea with highly different water qualities. The fact that these morphological and hydrographic conditions can also influence the fate of fish stocks has now been shown by a team of fisheries biologists from GEOMAR Helmholtz Centre for Ocean Research Kiel and the National Institute of Aquatic Resources (DTU Aqua) at the Technical University of Denmark. For their publication in the international ...

New research from the University of Adelaide has delved into the reasons why some people are unable to break free of their delusions, despite overwhelming evidence explaining the delusion isn't real. In a new paper published in the journal Frontiers in Psychology, University of Adelaide philosopher Professor Philip Gerrans says dreams and delusions have a common link – they are associated with faulty "reality testing" in the brain's higher order cognitive systems. "Normally this 'reality testing' in the brain monitors a 'story telling' system which generates a narrative ...

A proposal for reformulating the foundations of biology, based on the 2nd law of thermodynamics and which is in sharp contrast to the prevailing genetic view, is published today in the Journal of the Royal Society Interface under the title "Genes without prominence: a reappraisal of the foundations of biology". The authors, Arto Annila, Professor of physics at Helsinki University and Keith Baverstock, Docent and former professor at the University of Eastern Finland, assert that the prominent emphasis currently given to the gene in biology is based on a flawed interpretation ...

Butterflies are probably best-loved insects. As such, they are relatively well studied, especially in the United States. Eastern parts of the country are explored most thoroughly. First eastern US butterfly species were described by the father of modern taxonomy Carl Linnaeus himself, over 250 years ago. For the last two and a half centuries, naturalists have been cataloguing species diversity of eastern butterflies, and every nook and cranny has been searched. Some even say that we learned everything there is to know about taxonomy of these butterflies. Discovery of ...

Researchers at Women & Infants Hospital of Rhode Island have developed a biologic drug that would prevent the production of a protein known to allow ovarian cancer cells to grow aggressively while being resistant to chemotherapy. This would improve treatment and survival rates for some women. The work coming out of the molecular therapeutic laboratory directed by Richard G. Moore, MD, entitled "HE4 (WFDC2) gene overexpression promotes ovarian tumor growth" was recently published in the international science journal Scientific Reports, a Nature publishing group. "We ...

DURHAM, N.H. – By the time most people are 25, they have made the most important memories of their lives, according to new research from the University of New Hampshire. Researchers at UNH have found that when older adults were asked to tell their life stories, they overwhelmingly highlighted the central influence of life transitions in their memories. Many of these transitions, such as marriage and having children, occurred early in life. "When people look back over their lives and recount their most important memories, most divide their life stories into chapters ...

When they're not hanging upside down, stick insects don't need to stick. In fact, when moving upright, sticking would be a hindrance: so much extra effort required to 'unstick' again with every step. Latest research from Cambridge's Department of Zoology shows that stick insects have specialised pads on their legs designed to produce large amounts of friction with very little pressure. When upright, stick insects aren't sticking at all, but harnessing powerful friction to ensure they grip firmly without the need to unglue themselves from the ground when they move. ...

BOWLING GREEN, O.—They keep tanning, even after turning a deep brown and experiencing some of the negative consequences. Skin cancer is among the most common, preventable types of the disease, yet many continue to tan to excess. Research from Lisham Ashrafioun, a Bowling Green State University Ph.D. student in psychology, and Dr. Erin Bonar, an assistant professor of psychiatry at the University of Michigan Addiction Research Center and a BGSU alumna, shows that some who engage in excessive tanning may also be suffering from obsessive-compulsive (OCD) and body dysmorphic ...

A paper published in EPJ H provides the first English translation and an analysis of one of Albert Einstein's little-known papers, "On the cosmological problem of the general theory of relativity." Published in 1931, it features a forgotten model of the universe, while refuting Einstein's own earlier static model of 1917. In this paper, Einstein introduces a cosmic model in which the universe undergoes an expansion followed by a contraction. This interpretation contrasts with the monotonically expanding universe of the widely known Einstein-de Sitter model of 1932. The ...

New research has revealed that exposure to common family problems during childhood and early adolescence affects brain development, which could lead to mental health issues in later life. The study led by Dr Nicholas Walsh, lecturer in developmental psychology at the University of East Anglia (UEA), used brain imaging technology to scan teenagers aged 17-19. It found that those who experienced mild to moderate family difficulties between birth and 11 years of age had developed a smaller cerebellum, an area of the brain associated with skill learning, stress regulation ...
