Research demonstrates that the hormone PYY can inhibit eating in the morning, but not in the evening
Research at the Oregon National Primate Research Center (ONPRC) at Oregon Health & Science University has demonstrated that a hormone found naturally in the body has the ability to cause limited weight loss. Specifically, the research revealed that peptide YY (PYY) can reduce food consumption in the morning, leading to a mild level of weight loss in the short term. The research is
Tips from Harvard Health publications
Halloween is an exciting time for kids, and we can all help to make sure that children have a safe and fun holiday with the following tips from Harvard Health Publications, the publishing group at Harvard Medical School.
Candy
Kids will be less likely to overload on candy if they eat something before they go out. And they’ll be more likely to do that if you make it fun. One idea: Host a make-your-own-jack-o’
Published Oct. 20 in the online edition of the peer-reviewed journal Health Services Research, the study finds that the average $1,583 cost of substance abuse treatment is offset by monetary benefits such as reduced costs of crime and increased employment earnings totaling $11,487.
The researcher team used detailed data from 2,567 clients admitted to 43 treatment providers in 13 California counties during 2000 and 2001. The information was gathered via an automated system operated
Results from experiments conducted at the University of California, Santa Barbara may lead to profound changes in optical communications. The discovery is reported in the October 28th edition of the journal Science.
Physicist Mark Sherwin at UCSB explained that as information technology advances, scientists are intent on transmitting information much more quickly. “We are working toward sending information 100 times faster than it can be sent now,” he said. His research group h
New research in monkeys suggests that, although living in an “enriched” environment can make someone less vulnerable to abusing cocaine, once started, extended drug abuse can eliminate the social advantage the abuser originally had.
However, the research also shows that prolonged abstinence from drug use can give the recovering addict another chance, and that environment again becomes a major factor influencing the success of the recovery.

Scientists are one step closer to unraveling the complex mechanisms in the brain that regulate body weight. Working with mice — whose appetites are controlled by systems very similar to those in humans – they have identified a specific type of neuron that is essential for feeding behavior. Without these neurons, adult mice stop eating and undergo rapid weight loss.
Remarkably, the researchers found that absence of these neurons only influenced eating behavior when they were remov
A gene involved in B-cell development might play a role in multiple sclerosis. The results of a large study published today in the open access journal BMC Neurology reveal that multiple sclerosis (MS) patients are more likely to carry two specific genetic variations in the Early B-cell factor gene (EBF-1), than healthy individuals.
These variations – or polymorphisms – could play a causative role in MS or be located near other polymorphisms that do play a causative role in the disorder.
People living in deprived areas or working in manual occupations are less likely to receive cholesterol and blood pressure-lowering treatment than more affluent people
People living in deprived areas or working in manual occupations are less likely to receive cholesterol and blood pressure-lowering treatment than more affluent people, according to a paper published today [28 October] in the November issue of the British Journal of General Practice.

Undiscovered protein may help identify those whose disease will progress rapidly
Researchers have discovered a combination of tests that can more accurately predict who will develop type 1 diabetes. In the process, they’ve also uncovered signs of a new protein that may forecast a more rapidly developing form of the disease. Together, these findings could help researchers screen patients for clinical trials that eventually may lead to a vaccine or cure for type 1 diabetes.
Discovery could lead to prostate-cancer-specific diagnostic test and more effective treatment
Scientists at the University of Michigan Medical School, in collaboration with researchers at Harvard’s Brigham and Women’s Hospital, have discovered a recurring pattern of scrambled chromosomes and abnormal gene activity that occurs only in prostate cancer.
In a paper being published in the Oct. 28 issue of Science, the research team indicates that these chromosomal rea
A study by a group of Belgian investigators assessed the effects of aerobic exercise on various psychological dimensions, including well-being.
The first objective of this study was to compare the changes in physical self-concept, global self-esteem, depression and anxiety after participation in one of two 16-week psychomotor therapy programs for nonpsychotic psychiatric inpatients. The second objective was to study the relationship between changes in these variables.
A far reaching analysis of the potential futures faced by Europe’s information communication technologies (ICT) sector in a global context is laying detailed and incisive groundwork for policy makers to improve Europe’s situation by guiding ICT developments over the medium to long term.
“FISTERA aimed to investigate long-term trends in ICT to make a foresight analysis of changes in information communication technologies and uses by 2020,” says Ramón Compañó, of the Institute fo
Far from being a ‘throwaway society’, most of us go to considerable lengths to pass on unwanted household items to others, according to new research sponsored by the ESRC. And when it comes to making our mark in society, it is not just what we acquire but what we decide to get rid of that is important to us, says the study by researchers at Sheffield and Nottingham Universities.
The project examined how households in the Midlands and North-East got rid of ordinary, everyday consumer items
Today, most computer and consumer electronic devices require wires to record, play or exchange data. UWB (Ultra Wide Band) eliminates the need for such wires freeing people to perform activities such as remotely connecting their mobile PC to a printer, streaming audio from an MP3 player to speakers, or wirelessly transferring digital pictures to a photo print kiosk.

Three new Research Units, located in Bochum, Constance and Berlin, were approved for funding by the Joint Committee of the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) at its meeting on 20 October 2005. The DFG’s Research Units programme promotes interdisciplinary cooperation between outstanding scientists and researchers working on a specific research topic. The programme, which provides funding for a period of six years, is also intended to contribute to the establishment of n
Researchers from Imperial College London believe that when species become asexual they could be on their way to extinction.
The research, published in PLoS Pathogens, looks at the genetic structure of Penicillium marneffei, an asexual fungus. The researchers found that although P. marneffei spores were able to spread over large distances on currents of air, they were not able to ‘invade’ the new environments in which they landed.
P. marneffei is a fungus which causes di
