Team Sports May Deter Both Bullying And Violence

Science2.0 - May 6, 2013 - 11:17am

Bullying and violence are the latest cultural magnet for administrators in schools around the country, but the solution may not be paid commercials, more books or talks in the gym - it may be as simple as embracing team sports again.

At the Pediatric Academic Societies (PAS) annual meeting in Washington, D.C., researchers discussed their analysis of data from the 2011 North Carolina Youth Risk Behavior Survey to see if athletic participation was associated with violence-related behaviors, including fighting, carrying a weapon and being bullied. A representative sample of 1,820 high school students in the state completed the survey, which also asked adolescents whether they played any school-sponsored team sports (e.g., football) or individual sports (e.g. track).

Brighter Clouds: Organic Vapors Linked To Climate Cooling

Science2.0 - May 6, 2013 - 10:16am

Natural emissions and man-made pollutants have an unexpected effect; they make clouds brighter and have a cooling effect on the world's climate.

A quick primer: Clouds are made of water droplets, condensed on to tiny particles suspended in the air. When the air is humid enough, the particles swell into cloud droplets. It has been known for some decades that the number of these particles and their size control how bright the clouds appear from the top, controlling the efficiency with which clouds scatter sunlight back into space. A major challenge for climate science has been trying to understand and quantify these effects, which have a major impact in polluted regions.

MGE: Brain Cells Transplant Cures Epilepsy In Mice

Science2.0 - May 6, 2013 - 1:54am

Researchers were able to controll seizures in epileptic mice with a one-time transplantation of medial ganglionic eminence (MGE) cells into the hippocampus, which inhibit signaling in overactive nerve circuits.

Cell therapy has become a focus of epilepsy research, in part because current medications, even when effective, only control symptoms and not underlying causes of the disease, according to Scott C. Baraban, PhD of UC San Francisco, who led the new study. In many types of epilepsy, he said, current drugs have no therapeutic value at all.

Fat Cells Change Colour In Response To Temperature

Science2.0 - May 5, 2013 - 8:24pm
Mammals have the ability to adapt to a range of the temperature. While physiological homeostasis has a lot to do with this, part of the reason why mammals can adapt to cold temperatures is the presence of energy-burning brown fat cells. Unlike the large fat storage units in white fat cells (the cell type responsible for obesity), brown fat cells have the capacity to generate heat and provide insulation from cold. Recently, scientists discovered a population of fat cells with the properties of brown and white fat cells, a population dubbed the beige (brite cells) that emerges in mammalian fat as a result of cold adaptation.

Study Says Cigarettes Are Gateway To Marijuana

Science2.0 - May 5, 2013 - 5:00pm

Since marijuana is fast becoming legal again in America, it seems strange to be calling cigarettes a 'gateway' to it, but anti-smoking campaigns are almost as large a business as tobacco and so a paper at the Pediatric Academic Societies (PAS) annual meeting in Washington, D.C., today supports the notion that cigarettes are a gateway to marijuana. 

And, like everyone who picks a position and then wants data to support it, they used surveys of students. They found that students who smoked marijuana smoked more cigarettes than those who just smoked cigarettes. Cigarettes are so demonized a successful public relations campaign against drugs might be that it leads to more smoking. That will likely work far better than a fried egg in a television commercial.

London Murders: Stats Theory Shows Numbers Are Predictable

Science2.0 - May 4, 2013 - 7:42pm

Leading statistician Professor David Spiegelhalter claims today that the number of murders in London last year was not out of the ordinary and followed a predictable pattern. Spiegelhalter's report, published today in Significance, the magazine of the Royal Statistical Society, argues that shocking headline numbers are not as surprising as one might think.

Violence in London attracts headlines. After four people were murdered in separate incidents in London on July 10th, 2008, BBC correspondent Andy Tighe said "To have four fatal stabbings in one day could be a statistical freak." But could it? On July 28th thelondonpaper had the front-page headline: "London's murder count reaches 90". But Professor Spiegelhalter states that this number was predictable.

Link Between Religious Coping And Aggressive Treatment In Terminally Ill Cancer Patients

Science2.0 - May 4, 2013 - 7:42pm

BOSTON ––– In a new study of terminally ill cancer patients, researchers at Dana-Farber Cancer Institute found that those who draw on religion to cope with their illness are more likely to receive intensive, life-prolonging medical care as death approaches –– treatment that often entails a lower quality of life in patients' final days.

Previous research has shown that more religious patients often prefer aggressive end-of-life (EOL) treatment. The new study –– to be published in the March 18 issue of the Journal of the American Medical Association –– examined whether these patients actually receive such care. The study's findings suggest that physicians tend to comply with religious patients' wishes for more aggressive care.

Animal Families With The Most Diversity Also Have Widest Range Of Size

Science2.0 - May 4, 2013 - 7:42pm

DURHAM, N.C. -- Somewhere out there in the ocean, SpongeBob SquarePants has a teeny-tiny cousin and a humongous uncle.

That's just what one would expect from a new analysis of body sizes across all orders of animal life that was conducted by researchers at the National Evolutionary Synthesis Center (NESCent), in Durham, N.C. and the University of North Carolina, Chapel Hill.

Researchers Craig McClain and Alison Boyer created a giant database on body sizes across all orders of animal life and found that phyla -- families of animals grouped together by a similar body plan -- with the greatest diversity of species were also those with the largest range of body sizes.

Historical Increase In Corn Yield -- It's In The Roots

Science2.0 - May 4, 2013 - 7:42pm

Madison, WI, March 16, 2009 -- One of the most significant developments in agricultural growth in modern times has been the continuous and substantial increase in corn yield over the past 80 years in the U.S. Corn Belt.

This extraordinary yield advance has been associated with both breeding of improved hybrids and the ability to grow them at increased density. In a new study, published in the January-February issue of Crop Science, researchers have investigated the importance of the effects of leaves and roots on this dramatic increase in yield in the U.S. Corn Belt, and have found that the root structure may be the key to understanding how these crops have grown so efficient.

Squid Fishing Fight Not 'David Vs Goliath' But More Like 'Boy Who Cried Wolf'

Science2.0 - May 4, 2013 - 5:00pm
Is a David and Goliath battle brewing in commercial squid fishery, with larger purse seiners robbing "scoop" fishermen of their livelihoods, sometimes illegally?

That is what Virginia Hennessey wrote in the Monterey Herald. Hearing claims of three squid brail (smaller boat) fishermen, one might think that the larger seine vessel squid fishermen are illegally catching all of the allowable quota.

But that’s just not the case. In fact, not only is there an abundance of squid in California’s waters – more than enough to go around – most of the brail-boat fishing fleet have no problem with the current management structure.

What’s The Point Of Demarcation Projects?

Science2.0 - May 4, 2013 - 3:48pm
Readers of this blog know very well by now that, despite (or is it because of?) being both a scientist and a philosopher, I have often defended the idea that science and philosophy are distinct disciplines, and I am critical in particular of those who I think display a scientistic (i.e., intellectually imperialistic) attitude in wanting to expand the scope of science to pretty much everything that is worth knowing, usually at the expense of humanistic disciplines, philosophy in particular.

Disparity In Maternity Care: Lawyer Blames Government Budgets

Science2.0 - May 3, 2013 - 6:45pm

In the UK, health care is nationalized but a trial lawyer for maternity cases says that has made money a bigger concern in deciding who gets quality medical care. 

A report by The Royal College of Obstetricians and Gynaecologists (RCOG) said there was enormous disparity in the quality of care patients received across the country. It looked at the performance of maternity units in England during 2011/12 and found that rates of inductions, emergency cesareans and assisted deliveries were twice as high in some hospitals as others.

Bird Flu: H7N9 Infection Risk Mapped

Science2.0 - May 3, 2013 - 3:13pm

A map of avian influenza (H7N9) risk is now available. The map is comprised of bird migration patterns, and adding in estimations of poultry production and consumption, which are used to infer future risk and to advise on ways to prevent infection.

As of today, there have been 127 confirmed cases of H7N9 in mainland China with 27 deaths. A lack of information about the virus and its mode of transmission has led to public concerns that H7N9 could be a pandemic waiting to happen.
