A new University of Michigan study finds that teens using marijuana for medical reasons are 10 times more likely to say they are hooked on marijuana than youth who get marijuana illegally.
The study is the first to report on a nationally representative sample of 4,394 high school seniors and their legal or illegal medical marijuana use as it relates to other drug use. In the study, 48 teens had medical marijuana cards, but 266 teens used medical marijuana without a card.
But unfortunately, the standards of animal care vary greatly across countries and even across research institutes. The time has come to overhaul this system and replace it with globally enforced rules.-->
“I saw a werewolf with a Chinese menu in his hand,
Walkin' through the streets of Soho in the rain,
He was lookin' for the place called Lee Ho Fooks,
Gonna get a big dish of beef chow mein.”

" I saw Joe Mercola with the New York Times in his hand,
Looking for some way to explain,-->
What if I told you that half of the studies published in scientific journals today – the ones upon which news coverage of medical advances is often based – won’t hold up under scrutiny? You might say I had gone mad. No one would ever tolerate that kind of waste in a field as important – and expensive, to the tune of roughly US$30 billion in federal spending per year – as biomedical research, right? After all, this is the crucial work that hunts for explanations for diseases so they can better be treated or even cured.-->
Researchers studying wild banded mongooses in Uganda have discovered that these small mammals have either cooperative or selfish personalities which last for their entire lifetime.
The researchers investigated the selfish behavior of mongoose mate-guarding - where dominant males guard particular females - and the cooperative behavior of 'babysitting' and 'escorting' the young.
They found that cooperative mongooses that helped out with offspring care did so consistently over their whole lifetime but those that put in little effort never increased their workload.
Similar consistent behavior was found in mongooses that selfishly guarded mates for their entire life.
Antonio Aledo, Professor of Sociology at the University of Alicante, warns that "because of real estate speculation and the management of public budgets based on income from the real estate business, seismic risk has been forgotten."
As an example, he used the town of Torrevieja, where one of the biggest earthquakes in the province of Alicante took place in 1829 with more than 389 dead and 209 wounded. And things would not be much better now.
The rate of Australians dying from cancer is on a steady, downhill trajectory, thanks to powerful advances made in prevention, diagnosis and treatment of the disease. New data from the Australian Institute of Health and Welfare shows a promising outlook for those diagnosed with cancer.
Deaths from all cancers combined fell from 199 per 100,000 people in 1968, to 167 per 100,000 in 2012 - a decline of 2.6 deaths per 100,000 people per year.
“This confirms that we are steadily making improvements in most cancers, in terms of survival,” said Professor Timothy Hughes, Cancer Theme Leader at SAHMRI.
“And it’s coming from better prevention, better screening and better therapy.”-->
The discovery of unusual foraging activity in bacteria species populating our gut may explain how conditions like Inflammatory Bowel Disease (IBD) link to changes in the populations of bacteria in our gut. IBD affects 1 in every 250 people but its causes are unknown. Studies have shown that IBD patients have a different profile of gut microbes, which is called dysbiosis.
All of us have trillions of beneficial bacteria in our gut, but the combination of different species, known as the microbiome, varies. A crucial question has been whether IBD causes our microbiome to change, or whether an imbalanced microbiome could be triggering IBD. And exactly how does one affect the other? We need to study these interactions to define new targets for therapeutics.
A new small goby fish differs from its relatives not only in its size and colors, but also in the depth of its habitat (70-80 m) in the southern Caribbean. The scientists gave it the name Coryphopterus curasub in recognition of the Curasub submersible that was used in their deep-reef exploration.
Marine biodiversity inhabiting shallow Caribbean coral reefs has been studied for more than 150 years, but much less is known about what lives at depths just below those accessible with conventional SCUBA gear.
Thanks to the availability of a privately owned, manned submersible on the island of Curacao, the Curasub, scientists are now able to intensively study depths to 300 m (1,000 ft).
We also found that there is shared genetic influence across a range of subjects, even after controlling the exam results for general intelligence.-->
All those leftover pizza crusts you snatch from your kids' plates add up. Men gain weight after they become fathers for the first time whether or not they live with their children, reports a large, new study that tracked the weight of more than 10,000 men from adolescence to young adulthood.
Lightweight composite metal foams are effective at blocking X-rays, gamma rays and neutron radiation, and are capable of absorbing the energy of high impact collisions, and a new finding means the metal foams hold promise for use in nuclear safety, space exploration and medical technology applications.
Researchers conducted multiple tests to see how effective it was at blocking X-rays, gamma rays and neutron radiation. She then compared the material's performance to the performance of bulk materials that are currently used in shielding applications. The comparison was made using samples of the same "areal" density - meaning that each sample had the same weight, but varied in volume.
Both prescription and illegal drugs that are abused have been found in Canadian surface waters. New research shows that wastewater discharges flowing downstream have the potential to contaminate sources of drinking water with these drugs at relatively low concentrations.
The concentrations of cocaine, morphine, and oxycodone did not decline with distance downstream from the wastewater treatment plant discharge, and many of the drugs were not removed effectively by drinking water treatment plants.
The research is part of a special section on pharmaceuticals in the journal Environmental Toxicology & Chemistry.
10 percent of health care providers write an antibiotic prescription for nearly all (over 95 percent) of patients who walks in with a cold, bronchitis or other acute respiratory infection (ARI), according to a new study.
The figure is at one end of a spectrum showing the remarkable variation in how providers use antibiotics. At the low end, 10 percent of providers prescribe antibiotics during 40 percent or fewer patient visits.
