Breaking Down the (Fire) Wall in Iran

Friday, June 26, 2009

Call it the Iranian two-step. The government has done its most to throw up an internet firewall, staring on the day of the election. Reports are that connections are slow, emails are slower, and in some cases the internet has shut down entirely. How were the Iranians able to throw up a firewall so quickly, and how are scores of people getting around it? Cyber Security Expert Rafal Rohozinski joins The Takeaway with answers.

A New Look at Brain Injuries in Soldiers and Athletes

Tuesday, June 23, 2009

In the past, athletes involved in high-impact sports such as boxing or football would refer to the periods their brains went dim as "punch drunk." They'd find themselves thinking slowly, forgetting directions, suffering headaches. Now researchers think the symptoms may be indicative of a greater problem: the rare disease chronic traumatic encephalopathy. Athletes may not be the only victims— soldiers are also vulnerable. Joining The Takeaway with more is Chris Nowinski, director of the Sports Legacy Institute, a Boston-based nonprofit that has partnered with Boston University to study the long term affects of brain injuries like concussions on athletes and soldiers.

A 'Corpse Flower' with the Smell of Death

Tuesday, June 16, 2009

It has deep red flesh. It measures more than six feet high. It blooms only about once a decade. But the most memorable thing about the "Corpse Flower" at the Huntington Botanical Garden is that it gives off the stench of rotting flesh. The Takeaway is joined by Garden Director Jim Folsom, who's in San Marino, California, with the flower, Amorphophallus titanium.

South Africa: HIV Infections May Be Declining At Last

Friday, June 12, 2009

The news out of South Africa this week indicates there's something for the HIV-stricken country to celebrate. A new report says that HIV infections among young teens are down. In addition, the Western Cape is seeing fewer transmissions because more males are using condoms, and in the last three years the number of HIV infections has stabilized. Is the march of HIV slowing down?

The Takeaway is joined by Dr. Ernest Darkoh, a global health expert known for revolutionizing Botswana's HIV treatment program, to deconstruct the data. Click through for the full transcript of the interview.

Doctors to Schools: It's Your Job to Prevent Bullying

Tuesday, June 09, 2009

In July, the American Academy of Pediatrics will come out with a new statement on how to prevent childhood bullying. They suggest that schools adopt a program in which children are encouraged to reach out to victims and isolate bullies. Can schools really make bullying uncool? Dr. Robert Sege, one of the lead authors on the policy, joins The Takeaway with his big ideas.

For parents and teachers looking for advice on how to deal with bullying, head to today's New York Times to read Perri Klass's article, At Last, Facing Down Bullies (and Their Enablers).

Can Yogurt Slow the Spread of HIV?

Monday, June 08, 2009

HIV is sometimes referred to as a disease of the gut because of the voracity with which it attacks a victim's gastrointestinal tract. As researchers look at ways to limit the disease's affect on the body, a simple, stomach soothing solution came to mind: yogurt. More precisely, yogurt infused with friendly bacteria. Scientist Gregor Reid joins The Takeaway to talk about his work with HIV patients in Africa. There, in Tanzania, he has helped teach a group of "yogurt mamas" how they might serve up disease protection one cup at a time.

For more information, head to the pilot yogurt program's website, Western Heads East. Read more about the group, as well as other probiotic research, by checking out the article, A cultured response to HIV, in the June 2009 issue of the journal Nature Medicine.

We've Looked at Clouds From Both Sides Now

Tuesday, June 02, 2009

The skies are changing. Cloud enthusiasts in the United Kingdom believe they have found a new genus of cloud to put on the typical cloud list we all learn as children (you know: cirrus, nimbus, cumulus, stratus, and more). The enthusiasts are petitioning for the creation of a new cloud category. This kind of cloud appears to be thick and stormy; experts at the Royal Meteorological Society want to officially name it "Asperatus," after the Latin word meaning rough. Gavin Pretor-Pinney, founder of the Cloud Appreciation Society and author of The Cloudspotter's Guide joins The Takeaway to talk about cloud enthusiasts.

Could Mosquitoes Bring Disease to Galapagos Reptiles?

Tuesday, June 02, 2009

Biologists have discovered that mosquitoes on the Galapagos have evolved to pierce the skin of reptiles, including iguanas and endangered tortoises. The mosquitoes daily reptilian snack brings a threat of transferring vector-borne disease to the animals. Leaving scientists to ask the question: how can we keep the Galapagos as pristine as when Darwin first found them? Evolutionary biologist Simon J. Goodman joins The Takeaway with more.

Goodman is co-author of the research article, "Natural colonization and adaptation of a mosquito species in Galapagos and its implications for disease threats to endemic wildlife," which was published in this week's issue of the journal the Proceedings of the National Academy of Sciences.

How To Catch A Liar

Tuesday, May 12, 2009

Duped. Tricked. Hornswoggled. Deceived. How can you tell if someone is fooling you? According to a new article out in today's Science Times, it's all in how they tell the story. The new focus on interview content grows in part out of a frustration with previous methods that studied behavior — averted eyes, fidgeting, or sweating—and a lack in helpful technological advances. The more important point: How much detail does someone give you when they tell their story? Joining The Takeaway with more on this story is New York Times science reporter Benedict Carey. Listen in, and then try the technique out on a con-artist (or first date) near you.

Benedict Carey's article is part of the Science Times' special Forensics section. Read his article, "Judging Honesty By Words, Not Fidgets," and check out the rest of The New Forensics issue.

Also, if lying appeals to you, listen to Radio Lab's show on Deception.

Beating a polygraph test may not get you in the clear if you're lying. But just in case, watch this video for pointers.

I Am The Virus

Wednesday, May 06, 2009

Ever since this whole "swine flu" thing erupted it's been nothing but talk about humans, humans, humans. But what's it been like to be a virus these last few weeks? Today, we shrink down to take a look at life from the point of view of one of the world's smallest biological toxins. How, really, do viruses get out of one organism and travel to another? (Warning: It's pretty gross.) What perils face a virus that ventures outside the human body? Our microscopic tour guide is The Takeaway's favorite virus hunter, Dr. Susan P. Fisher-Hoch, an epidemiologist at the University of Texas School of Public Health and co-author of Level 4: Virus Hunters of the CDC.

If you want to see the view of the body a virus sees, all you have to do is watch Fantastic Voyage, a 1966 classic in which "four men and a beautiful lady" were shrunk down and sent into the bloodstream on a submarine (it was not yellow):

Hitting harder than a fist: Childhood bullying linked to teen psychosis

Tuesday, May 05, 2009

Bullying causes more than tears, according to new research. Scientists reporting in the May issue of the journal Archives of General Psychiatry say that childhood bullying can lead to teenage psychotic episodes such as delusions and paranoia. Here to tell us more is study co-author Dieter Wolke, a professor of developmental psychology and individual differences at the University of Warwick, England.
"If they're in a class they're going to pick on every child. Then they're going to hone in on the child that shows a reaction — for example cries or runs away — and has very little support."
—University of Warwick professor Dieter Wolke on bullying among children

Virus hunters chase down the swine flu

Wednesday, April 29, 2009

The world has found a new strain of flu, so now what? Enter the virus hunters. This pack of epidemiologists, virologists, and infectious disease experts (sounds like a fun party) are fast on the bug's tail, looking for answers that may help us control its spread. What are they trying to figure out? How long will it take to rustle up some answers? And when you're an epidemiologist chasing down a flu virus, what do you do in your lab all day? The Takeaway is joined by Dr. Susan P. Fisher-Hoch, an epidemiologist at the University of Texas School of Public Health and co-author of the book, Level 4: Virus Hunters of the CDC. ,br/>
"It's a very bad idea just to go to the doctor's with a mild fever because that's the place to get infected because everybody will go there with their infected kids and their infected older people."

Can we make a vaccine to stop swine flu?

Tuesday, April 28, 2009

Swine flu is continuing it's spread around the globe, and there's one word on everyone's lips: vaccine. Can researchers create a vaccine that will stop the virus with one quick jab of a needle? How quickly can a vaccine be created? And what can we do to prevent the spread of the flu before a vaccine is created? Dr. Anthony Fauci, director of the National Institutes of Allergy and Infectious Diseases, explains.

We were lucky enough to be able to nab Dr. Fauci by phone before he heads to Capitol Hill this afternoon, where he will testify at an emergency Senate meeting about the federal government's response to swine flu.

Putting swine flu in perspective

Tuesday, April 28, 2009

The last few days we've been inundated with numbers and swine flu facts. Eighty deaths in Mexico jumped to 100. Twenty sickened school children in Queens became 40. We know that pork's fine to eat, and that we might not want to travel south of border. But what about some of the contextual facts — are people getting sicker more quickly in this outbreak than they have in others? Will border security stations really help? Here to answer the Big Picture questions is Dr. Richard Wenzel, The Takeaway's go-to swine flu epidemiologist.
"As the numbers expand and we continue to see mild cases, then we have to turn the focus back to what's different about the patients in Mexico."

Swine flu: We know it's spreading, but not much else

Tuesday, April 28, 2009

We continue our coverage of the outbreak of swine flu that appears to be spreading rapidly across the globe. While the epicenter of the outbreak is in Mexico, there are 50 confirmed cases of people sickened from swine flu in the U.S., including 28 at one New York City school. Around the world, 6 are confirmed in Canada; 2 are confirmed in Scotland (with 7 suspected); at least 10 are suspected in New Zealand. In Spain, there is one confirmed case and 17 suspected ones; one suspected in France and one suspected in Israel. This may appear to be a fast moving story to us non-scientists, but in the medical community, they are taking things slow. The Takeaway talks to Dr. Michael Edmonds, an epidemiologist at Virginia Commonwealth University to find out why.

Also joining the conversation is Tom Skinner, the spokesperson for the Center for Disease Control and Prevention to give us the latest on the outbreak in the United States. We also will get a report from Ioan Grillo, Mexico correspondent for Time Magazine. He joins us from the heart of the outbreak in Mexico City.
"The best antidote to fear really is information, so we really do want people to be informed about what's going on and know that there really are steps that they can take to protect themselves and others."
—Tom Skinner of the Centers for Disease Control on swine flu protection

Investigation begins into death of 21 horses

Tuesday, April 21, 2009

Polo fans and equestrian-lovers watched in horror as seven horses sickened and died in front of their eyes. The horses were meant to take the field for a polo match in Wellington, Florida on Sunday afternoon. Soon seven other horses fell sick. Veterinarians rushed the fields, but were unable to save a single horse. By Monday, 21 horses, all from the same Venezuelan team, had died. Now, investigators are searching for the cause. The Takeaway turns to Brian Haas, a newspaper reporter on the ground in Florida and Dr Celeste Kunz, a horse veterinarian, to try and piece together this equine mystery.

For more, read Brian Haas' article, PBSO and state investigations launched in deaths of 21 horses in Wellington in the Sun Sentinel.
