Rats fed a high fat diet were less sensitive to a hormonal ’stop eating’ signal than rats on a low fat diet when they were given access to a high calorie, high fat snack that the animals find yummy.
Dr. Mihai Covasa, assistant professor of nutritional sciences and a member of the Penn State Neuroscience Institute, led the study. He says, “When we gave the rats doses of a ’stop eating’ hormone, the rats on the low fat diet significantly suppressed their intake
Recent suicide attempters treated with cognitive therapy were 50 percent less likely to try to kill themselves again within 18 months than those who did not receive the therapy, report researchers supported by the National Institutes of Health’s (NIH) National Institute of Mental Health (NIMH) and the Center for Disease Control and Prevention (CDC). A targeted form of cognitive therapy designed to prevent suicide proved better at lifting depression and feelings of hopelessness than the usua
China’s rainy season has led to serious flooding in the north-east and south of the country. A joint Chinese-European team is gathering Envisat radar imagery of the developing situation to give the authorities a way to swiftly assess affected areas and plan their responses.
Summer flooding is nothing new in these regions of the People’s Republic of China (PRC), though this year it is proving particularly severe, with more than 800 casualties countrywide and 2.45 million peop
This week scientists of the Flanders Interuniversity Institute for Biotechnology (VIB) will once again publish a breakthrough in their research regarding Alzheimer’s disease. The researchers, this time connected to the Catholic University of Leuven, discovered the function of one of the most important proteins related to Alzheimer’s disease. They have indicated that the protein stimulates the growth of nerve paths in the brain, which is essential for recovery after brain damage. The results are p
A team of researchers from the UK and France used SOHO, ACE and the four Cluster spacecraft to study a huge eruption on the Sun, tracing its progress from birth to when it reached Earth.
The team, led by scientists from University College London, identified the source of a ‘coronal mass ejection’ (CME) and analysed how its magnetic field changes on its path to Earth.
Triggered by a massive explosion on the Sun with millions of times more energy than a nuclear bomb, these
The broadband boom is creating an ever-increasing demand for more capacity and higher rates of data transfer on both fixed-line and wireless networks. Helping to meet that demand, without the need to lay costly new infrastructure, is the LABELS project.
“Consumers are soon going to want data streams of 100 megabits per second in their homes and eventually 1 gigabit per second,” says José Capmany, a researcher at Valencia Technical University in Spain and the coordinator of the IST
Researchers have obtained further evidence that one of the oldest biological laws can also be applied to bacteria living in the sump tank reservoirs of machines in an engineering workshop in Oxford, according to a paper published in Environmental Microbiology.
Scientists from the Centre for Ecology & Hydrology (CEH) in Oxford, found that the patterns of abundance and genetic diversity of bacteria living in oil-based metal-cutting fluid reservoirs were similar to those found in
One of the two Galileo satellites currently under development, GSTB-V2/A, has arrived at ESA’s European Space Research and Technology Centre to undergo testing.
Two satellites are being developed for the Galileo System Test Bed – Version 2, which will make up the first phase of in the ’in-orbit validation’ of the Galileo system.
The primary mission of the first Galileo satellites is to secure the Galileo frequency filings, validate new technologies for operational use, c
Electrical exercise system gives paralysis sufferers power to recover strength
People affected by paralysis could enjoy more independence, better health and a higher quality of life thanks to an innovative system designed to improve fitness and increase arm strength.
It uses electrical signals to stimulate movement in arm muscles where function has been lost, making it possible to work an arm-exercise machine (similar to an exercise bike but worked by the arms).
What young people say at the age of 11 about their intentions to stay at school post-16 is a good predictor of whether or not they will actually stay in post-compulsory education, according to a major study at the University of Reading.
Research conducted by Professor Paul Croll, and funded by the Economic and Social Research Council (ESRC), looked at the intentions of young people expressed through their years in secondary school and compared these with their behaviour at th
A new theory that explains why the language of our genes is more complex than it needs to be also suggests that the primordial soup where life began on earth was hot and not cold, as many scientists believe.
In a paper published in the Journal of Molecular Evolution this week, researchers from the University of Bath describe a new theory which they believe could solve a puzzle that has baffled scientists since they first deciphered the language of DNA almost 40 years ago.
One of the biggest obstacles facing computer systems today is the problem of memory latency, the time a computer must wait to access the data stored in memory despite faster processor speeds. Two demonstrators reveal that optoelectronics may offer solutions.
“Your domestic PC these days can have a processor of two GHz and faster – this is quite common – but the processor power will often be wasted because the real bottleneck in computer processing is the memory.” That is John Sn
Research published in the journal Space Weather warns that massive gaps in our understanding and monitoring of space weather will effectively block US plans for a manned mars space mission. The study, led by University of Warwick researcher Dr Claire Foullon, draws on work that Dr Foullon and colleagues carried out for the European Space Agency on radiation hazards and space weather.
Dr Foullon points to particular concerns about the radiation dangers of Solar Proton Events (SPEs) particula
The Nuclear Physics Group at the University of Surrey has been awarded a large scale grant worth almost half a million pounds (£483k) from the UK Engineering and Physical Sciences Research Council (EPSRC) to synthesise and study the structure of the most exotic forms of nuclear matter created to date.
The Surrey collaboration, led by Dr. Paddy Regan, Reader in Nuclear Physics, has won a four-year grant to perform a series of experiments at the € 1Billion GSI-FAIR heavy-ion resear
MOBI-MAT is an extremely tough, ultra-light, non-slip ground matting developed by Deschamps of France that gives temporary and safe access to users across unstable, natural surfaces (covered with sand, mud or snow). MOBI-MAT ground cover has applications in a huge range of areas. It can be used by: holidaymakers on the beach; yachting enthusiasts and lifeguards as a boat-ramp; walkers as pathways to help protect sensitive environments; work crews as a temporary roadway; helicopter crews as a helipad
