You may have heard that dollar bills harbor trace amounts of drugs.
But those greenbacks in your wallet are hiding far more than cocaine and the flu. They're teeming with life.
Each dollar bill carries about 3,000 types of bacteria on its surface, scientists have found. Most are harmless. But cash also has DNA from drug-resistant microbes. And your wad of dough may even have a smudge of anthrax and diphtheria.
In other words, your wallet is a portable petri dish.
Documents obtained by a group opposed to hydrofracking in New York show that the Cuomo Administration is conducting a thorough and comprehensive health study on the controversial natural gas drilling process. The Finger Lakes-based organization is wondering, why then, the review has been conducted almost entirely in secret.
Young adults who smoke marijuana at least once a week showed changes in the size and shape of two key brain regions, according to a new study of 20 pot smokers and 20 non-pot smokers between 18 and 25.
This is the first time recreational marijuana use has been connected to significant brain changes.
The findings, a collaboration between Northwestern University and Massachusetts General Hospital/Harvard Medical School, were published in The Journal of Neuroscience.

Thousands of Massachusetts residents are being surveyed as part of multi-year, multi-million dollar research project on the social and economic impacts of introducing casino gambling to the state.
The members of the UMass Amherst led research team say initial results will be reported to the Massachusetts Gaming Commission in September. These findings will be the baseline that will be used to measure changes in problem gambling, domestic violence, housing prices and a host of other socio-economic factors as casinos open over the next one to three years.
This week, scientists at the Smithsonian's National Museum of Natural History will start unpacking some rare and precious cargo. It's something the Smithsonian has never had before — a nearly complete skeleton of a Tyrannosaurus rex.
When I had a second baby earlier this year, my three-year-old suddenly seemed enormous. "Check out the size of those feet!" I marveled. She seemed so heavy, so tall, so substantial.
She even seemed more capable, more robust. Images of airborne cookware and toppling bookshelves faded. The staircase didn't seem quite so treacherous. Instead, I trusted in her basic competence to scale the kitchen stools without incident and to keep (most) sharp-and-pointy things beyond the envelope of her person.
It wasn't just me: my husband reported the same experience.
Advanced sciences like astronomy require years of study and graduate degrees. And the soaring cost of college can be a heavy obstacle for low-income and minority students hoping to break into those fields.
A program at the City University of New York hopes to lift that burden by providing scholarships and one-on-one mentoring to underrepresented students.
The report details recent impacts of climate-related extremes such as wildfires, droughts and floods and predicts the vulnerability of human and natural resources, including a stress on crops and water resources.
Recent observations of so-called "gravitational waves" are providing astronomers with the strongest confirmation yet of cosmic inflation, a theory that says the universe rapidly expanded following the Big Bang.
Why, exactly, did the universe balloon by 100 trillion trillion times, in less than the blink of an eye, 13.8 billion years ago?

Pediatricians often recommend some mental health counseling for children who have behavior problems like defiance and tantrums. But counseling can be hard to find. Children are much more likely to get help if the counselor is right there in the doctor's office, a study finds.
The children in the study had behavior problems, and many also had attention deficit hyperactivity disorder or anxiety. They were 8 years old, on average, and two-thirds were boys.
Researchers at Yale have identified what they say is a more efficient way to screen thousands of spider neurotoxins against different pain receptors in the body. Above, the Peruvian Green Velvet tarantula.
Drug companies like operating in the shadows, but a recent move by Johnson and Johnson may change all that. In collaboration with Yale University's Open Data Access Project (YODA), the pharmaceutical giant will now share its clinical trial data with researchers.
The actresses Teri Garr and Annette Funicello, the television hosts Montel Williams and Neil Cavuto, the writer Joan Didion, Ann Romney, the wife of the presidential candidate Mitt Romney, the comedian Richard Pryor. These are some of the people that you quote-unquote know that have, or in Pryor's case had, Multiple Sclerosis.
Researchers used medical record data for more than 61,000 patients from 2005 to 2011. They studied more than 20 common problems patients typically encounter after admission to a hospital -- things like drug reactions, bed sores, and infection.

Think about your fifth-birthday party. Maybe your mom carried the cake. What did her face look like? If you have a hard time imagining the way she looked then rather than how she looks now, you're not alone.
The brain edits memories relentlessly, updating the past with new information. Scientists say that this isn't a question of having a bad memory. Instead, they think the brain updates memories to make them more relevant and useful now — even if they're not a true representation of the past.
At Able Care Pharmacy and Medical Supplies in Enfield, Ashraf Moustafa often tries to avert disasters involving drugs displayed on his store’s shelves.
Moustafa, the pharmacy manager, recently spoke to an elderly woman seeking ways to treat dark blue patches on her arms. Instead of suggesting any remedies, he asked the woman what medicines she was taking, and discovered that she was dangerously mixing over-the-counter anti-inflammatory drugs with aspirin and the prescription blood thinner Plavix. He sent the woman to the hospital, fearing that she was suffering from internal bleeding.
“People have the impression that if a drug is approved for over-the-counter use, then it must be much safer than prescription medicine,” Moustafa says. “That’s when trouble happens.”
