Scientific American - HealthScience news and technology updates from Scientific American For Healthy Cities, Government and Business Need to Reverse RolesFri, 03 Feb 2012 14:00:00 EST Okay, I have to be honest with you. I love a city, and a downtown with walkways and tunnels and bus stops that tell me where my buses are via GPS and everything else, but sometimes you can just have more connectivity than you need. Remember the internet-connected toaster, that singed the weather forecast into your morning toast? Well, meet the Big Belly Solar Trash Compactor, a precocious trash can that lives in Raleigh, NC. [More]More with Maryn: McKenna on Antibiotic ResistanceThu, 02 Feb 2012 22:10:08 EST Journalist and author Maryn McKenna talks about antibiotic resistance in agriculture and human health, MRSA, and a brief return to the subject of fecal transplants. [More] Concussion Is a Serious Problem for Child AthletesWed, 01 Feb 2012 08:00:00 EST The dangers of life in the National Football League made headlines in 2009, when a study commissioned by the NFL found that retired players were 19 times more likely than other men of similar ages to develop severe memory problems. The obvious culprit: continued play after repeated head injuries. Indeed, head injury can imitate many types of neurodegenerative disease, including Parkinson’s disease and, as journalist Jeffrey Bartholet reports in “The Collision Syndrome,” on page 66, perhaps even amyotrophic lateral sclerosis, commonly referred to as Lou Gehrig’s disease.

The Union of Concerned Scientists FDA at a Crossroads meeting also covered problems with drug approval. This is perhaps no better illustrated than by the disappointing decision by Secretary of Health Kathleen Sebelius to deny the emergency contraceptive, Plan B, over-the-counter status for women under the age of 17 . This was a particular disappointment to many because President Obama had promised that decisions at the FDA would be made based on science, rather than politics. Some of us, naively, hoped that change we can believe in was real, having forgotten that the Tooth Fairy wasn t.

When I was a kid, I used to spend hours listening to Adam Carolla and Dr. Drew Pinsky on their Sunday night call-in radio show Loveline . I listened so often that I began to incorporate one of their catchphrases – “good times” – into my daily conversations. Scientists have a name for this phenomenon: behavioral mimicry .

Zaki NEW YORK Sparks flew Thursday night at a New York Academy of Sciences panel discussion about whether or not certain recent research into the H5N1 avian flu virus has created a major biosecurity threat and what, if anything, to do about it. [More]Could an Infection Cause Tourette's-Like Symptoms in Teenage Girls?Thu, 02 Feb 2012 18:05:00 EST Over the weekend Erin Brockovich made the news yet again as she and her nonprofit team descended on the village of Le Roy, N.Y., determined to test for environmental toxins that might be giving the town's teenagers symptoms of Tourette's syndrome. She has reportedly been stonewalled thus far by local officials, who have already ruled out toxins as the cause of last October's sudden outbreak of tics and involuntary movements in 12 girls who attend Le Roy Junior–Senior High School. An environmental testing company surveyed the air and water and found nothing amiss, and a local neurologist concluded upon examining the girls that they had "conversion disorder," a catchall moniker for physical symptoms that originate in the mind because of stress, trauma or even mass hysteria.

It occurs when there is a sudden acceleration or deceleration of the head, a process depicted here in this animation. [More]New Map Shows that Most Lyme-Infected Ticks Are in Northeast, Northern MidwestWed, 01 Feb 2012 17:00:00 EST Female blacklegged tick courtesy of Graham Hickling/University of Tennessee Lyme disease is notoriously tough to diagnose. The symptoms often don’t appear for one or two weeks after a bite and can vary from feeling flu-ish to longer-term neurological damage. And ticks seem to lie in wait throughout much of the U.S., prepared to pounce and infect a passerby.

[More]Controversy: Can Repeat Concussions Cause Lou Gehrig's Disease? (preview)Thu, 02 Feb 2012 07:05:00 EST Kevin Turner was a premier athlete in the National Football League, a fullback who could run, catch and block. At 6' 1" and roughly 230 pounds, he was slightly undersized for his position, but he had tremendous thrust in his legs and used all of it to launch himself into players who were bigger than he was. He played for the New England Patriots from 1992 to 1994, then joined the Philadelphia Eagles, with whom he stayed until his abrupt retirement in 1999. Some called him “the Collision Expert”--a nickname he got because of the gouges he collected on his helmet.

Dozens of my new neighbors, Sierra Leone s Mende people, emerged from their thatch-roof houses, looking cross at being woken up and not exactly welcoming. We unloaded some of my gear underneath the dripping eaves, and as I tried to find something dry to wear, I realized that all my equipment: books, electronics, and gear, were soaking wet in the back of the truck. I had spent the entire day with a driver whose accent was so thick that several minutes into a conversation about cheese, I realized we were discussing chiefs, not cheddar. I had eaten entrails soup for lunch, been bounced over dirt roads for over 10 hours, and knew not a single person around me. I was suddenly glad it was dark so that nobody could see the silent tears streaming down my face.

If you didn't know better, you might assume these were extruded by a Play-Doh Fun Factory. CDC Public Health Image Library Image #11151. CDC/ Margaret Williams, PhD; Claressa Lucas, PhD;Tatiana Travis, BS In July 1976, a convention of members of the American Legion — a veterans’ group — was meeting in Philadelphia at the Belleville Stratford Hotel in honor of America’s bicentennial. Soon, 221 attendees would be sickened and 34 dead of an illness it was believed no one had ever seen before. Swine flu was suspected , as were toxic chemicals or terrorism of some sort. None of these proved to be the cause.

[More]Brain Injury Rate 7 Times Greater among U.S. PrisonersSat, 04 Feb 2012 08:00:00 EST A car accident, a rough tackle, an unexpected tumble. The number of ways to bang up the brain are almost as numerous as the people who sustain these injuries. And only recently has it become clear just how damaging a seemingly minor knock can be. Traumatic brain injury (TBI) is no longer just a condition acknowledged in military personnel or football players and other professional athletes. Each year some 1.7 million civilians will suffer an injury that disrupts the function of their brains, qualifying it as a TBI.
