For decades, parents have been told they can deter adolescent misbehavior by monitoring and setting firm limits on their children’s activities and friendships. In 2000, this assertion was challenged by papers published in the journals Child Development and Developmental Psychology. The authors of these papers cautioned parents not to assume that controlling, supervising, and monitoring their children would reduce the likelihood that adolescents would become involved in problem behavior such as drug
Chronic Fatigue Syndrome (CFS) is nearly four times as common in veterans of the first Persian Gulf War as in nonveterans, according to a new study. The study, to be published May 14, 2004 in the online edition of Muscle & Nerve, examined the possibility that genetic factors may play a role in developing the disease. The full study will be available via Wiley InterScience .

Exploring the connection
Out-of-school time can be developmentally enriching for adolescents, providing experiences that support growth in healthy behaviors and academic success, or it can be detrimental, affording opportunities for unsupervised or harmful activities that increase the likelihood adolescents will engage in delinquent activities that lead to declines in overall well-being.
For young adolescents growing up in impoverished families and communities, the need for s
Malfunction of the motor that powers sperm plays havoc with more than fertility: it may also be the root cause of the rare genetic disease Bardet-Biedl syndrome (BBS).
Reporting in the journal Cell tomorrow, researchers from the UK, US and Canada reveal they have discovered a novel gene for BBS that’s necessary for the generation of a cell’s cilia and flagella – hair like tentacles used to propel a cell or sweep substances over their exterior.
Cilia and flagella are commonly known a
At a time when football clubs are seeking to enhance revenue streams and shirt sponsors are looking to add value to their deals, selecting the right sponsorship partner and professionally managing a deal with them has never been more important.
“When football shirt sponsorship contracts are agreed, football clubs and shirt sponsors normally make announcements about their commitment to one another. The question is: what does ‘making a commitment’ actually mean?” says sports marketing expert
Throughout Europe the recovery of abandoned land known as ‘brownfield sites’ is becoming increasingly important. Former industrial or commercial properties where operations may have resulted in environmental contamination, they often impose environmental, legal and financial burdens on the surrounding communities. Left vacant, contaminated sites can threaten the economic viability of adjoining properties.
One obstacle to their re-use is the uncertainty over how blighted the land is, and sta
At a microscopic level, water molecules behave rather like the needle of a compass. Just as the needle moves when surrounded by a magnetic field (such as that of the Earth), water molecules move slightly in one direction when there is an electric field. Or at least that is what physicists thought till now. Research at the Universitat Autònoma de Barcelona has shown that, in water trapped in the bubbles of a detergent, it is not quite like that: water molecules have a surprising ability to organize th
GPS today has endless uses amongst which is the novel one for taxis in the Basque city of Donostia-San Sebastian. In order to answer customers in the quickest possible time, a GPS system has been installed in cabs belonging to the Vallina TeleTaxi company.
The new communication system for the drivers of the taxis has been installed now for two months – the radio taxi is a thing of the past.
The British company, Auriga System, was commissioned to install the GPS vehicle location sy
Animals often house substantial microbial populations within their bodies. While in some cases the microorganisms are necessary for host survival or reproduction, in the preponderance of cases they are not. It is of great interest to understand whether facultative associations with microorganisms ever benefit the host in lesser ways. Previously, a facultative symbiont was identified in pea aphid which was associated with host plant specialization – there was a dramatic increase in fecundity on clover
Browsing by mammals often has a serious impact on the growth of tree saplings and the regeneration of forests. However, there is much uncertainty with regard to effects on soil nutrient cycling and in turn, potential consequences for the growth of plants.
In a paper to be published in the June issue of Ecology Letters, researchers from Lancaster University and the Centre for Ecology and Hydrology have demonstrated a direct link between above-ground herbivory and below-ground nutrient cyclin
Extinction doesn’t just affect the species that disappears – it alters entire communities, changing both how the community as a whole and the individual species within it will respond to environmental degradation, according to results published in the May 13 issue of Nature.
With extinction continuously altering the fates of plants and animals, the researchers say it may be extremely difficult to predict which organisms will be the next to cease existing and that the wisest conservation
Concerns that resulted in moratorium on laparoscopic procedure resolved
When performed by experienced surgeons, minimally invasive laparoscopic surgery is a safe and effective alternative to standard open surgery for most patients with cancer that is confined to the colon.
That is the main finding of a seven-year international study, which will be published in the May 13 issue of the New England Journal of Medicine. The study involves 872 patients with colon cancer and is th
July 2003 saw a significant discovery in Ecuador by IRD archaeologists: 4000-year-old structures indicating the presence of one of the first great Andean civilizations in the upper Amazon Basin, where their presence had not been suspected. The site is at Santa Ana- La Florida in the south of Ecuador. Subsequent systematic excavations of other parts of the site led to the discovery of sophisticated architectural complexes. Among these are a tomb and a range of diverse vestiges: ceramic bottles, plain
Such research could offer important evolutionary insights into the nature of intelligence in primates
Until now, primatologists believed lemurs to be primitive, ancient offshoots of the primate family tree, with far less intelligence than their more sophisticated cousins, monkeys, apes and humans. But at the Duke University Primate Center, with the gentle touch of his nose to a computer screen, the ringtail lemur called Aristides is teaching psychologist Elizabeth Brannon a startling
New research shows that what was once considered a universal constant in oceanography could actually vary in the future – depending on the ecological scenarios that affect competition for resources among microscopic marine plants, which play a role in global climate.
The future of these plants, called phytoplankton, is important because they exist at the base of the marine food web and represent a large source of food for fish. Also, they affect global climate by using atmospheric carbon di
Tufts University groundbreaking research on caterpillar locomotion could pave the way to designing first flexible robot to navigate through human body, pipelines, reactors
Tufts University neurobiologist Barry Trimmer is inching his way to unlocking the secrets behind the way caterpillars maneuver and climb, and is using that knowledge to one day build flexible robots that could explore internal organs, blood vessels and the insides of pipelines.
