The One True Path?

The Scientist magazine, October 2010.

Endocrinologist Kevin Niswender and neuroscientist Aurelio Galli hadn’t really kept in contact since they parted ways after beginning their respective careers at Vanderbilt University in the 1990s. But about 10 years ago, Niswender, who went to medical school at Vanderbilt, and Galli, who did a postdoc there, both landed faculty positions back at the Nashville, Tennessee, university. They rekindled their friendship and often discussed their research during convivial family dinners.

Niswender, who studies diabetes and metabolism, and Galli, who specializes in the neurobiology of addiction, had never collaborated scientifically. They can’t remember the exact moment they decided to do so, but gradually they realized that some of their research interests overlapped. The pair discussed a number of clinical hints that diabetes and mood disorders are related: Defects of the insulin pathway run in families with schizophrenia, diabetics are more likely to be depressed, and insulin signaling somehow affects dopamine levels in the brain.

Dr. James’s Fever Powder, circa 1746

The Scientist magazine, October 2010.

Dr. James’s fever powder, patented by English physician Robert James, claimed to cure fevers and various other maladies, from gout and scurvy to distemper in cattle. Though its efficacy was often questioned, the powder had “a long tradition of usage,” from its introduction in 1746 well into the 20th century, says John Crellin, a professor of medical humanities at Memorial University of Newfoundland. It was even prescribed to King George III when he was suffering from cataracts, rheumatism and dementia at the end of his life. Read More >

U.S. Apologizes for Deliberately Infecting Guatemalans With Syphilis

Discover, October 1 2010.

The United States government officially apologized to Guatemala today for unethical medical experiments conducted by American researchers in the country over 60 years ago, in which unwitting subjects were deliberately infected with syphilis.

Secretary of State Hillary Rodham Clinton and Health and Human Services Secretary Kathleen Sebelius said they were, in their words, “outraged that such reprehensible research could have occurred under the guise of public health.” Read More >

Sunbather Singed by Shiny Hotel’s Reflected “Death Rays”

Discover, September 28 2010.

Poolside at Las Vegas’s Vdara hotel is a dangerous place to be. That’s according to one tourist who claims he almost had his hair singed off by a “death ray”—the term used by some hotel employees—reflected from hotel’s shiny facade.

The hotel’s spokesperson would understandably prefer to use the term “hot spot” or “solar convergence” to describe the spot near the pool where the sunlight reflects off the building’s side. Hotel guests say they have seen plastic cups and bags melt from the heat of the ray. The Review-Journal was tipped off to the problem by the story of a poolside lounger named Bill Pintas from Chicago. Read More >

It’s a Bra! It’s a Dust Mask! It’s Both! And Now, It’s for Sale

Discover, September 27 2010.

The Emergency Bra, which won both the Ig Nobel prize in public health and a spot on TIME’s list of the Worst Inventions of 2009 is now available through the website, www.ebbra.com for $29.99. CNET explains its intended use:

The bra is, of course, meant to be taken off, something most adults presumably have experience with. Once removed, it separates into two masks which, when placed over the nose and mouth, filter out particles…. Read More >

Touching a Boo-Boo Really Does Make It Feel Better

Discover, September 24 2010.

Clutching an injury does make it feel better, according to a study published in Current Biology, reducing the pain on average 64 percent. But only if the injured party is the one doing the clutching (insert your own self-touching joke here). It doesn’t work if someone else does it. Study coauthor Marjolein Kammers explained to the Daily Mail what this means:

“Pain isn’t just the signals coming from the body to the brain, but it is also the way the brain processes those signals,” she said. Read More >

The Public Speaks: Best Insulting New Names for High Fructose Corn Syrup

Discover, September 23 2010.

The New York Times’s health blog is asking scientists and readers what they would rename high fructose corn syrup, if they were given the chance. The ubiquitous sticky sweetener is considered poison by many foodies and some public health officials, who worry that HFCS-packed processed foods contribute to obesity. But the companies that make the sweetener–the Corn Refiners Group–are hoping that changing the name of the product will change its image, as their president told the New York Times:

“Clearly the name is confusing consumers,” said Audrae Erickson, president of the Washington-based group, in an interview. “Research shows that ‘corn sugar’ better communicates the amount of calories, the level of fructose and the sweetness in this ingredient.” Read More >

That’s a Relief: Ice Cream Doesn’t Cause Brain Damage

Discover, September 22 2010.

So sweet… so painful. You try to hold back, to stop yourself from over-indulging, because you know what will happen: That crippling, brain-piercing pain of the ever-feared brain freeze will ruin your ice cream love-fest.

Bjorn Carey of Popular Science discussed this terrifying condition with medical experts, seeking their opinion:

First, let’s get one thing straight. “This condition is referred to as an ‘ice-cream headache,’ ” says Stacey Gray, a sinus surgeon at the Massachusetts Eye and Ear Infirmary in Boston. “It’s a very technical term.” Read More >

Does a Common Cold Virus Boost Chances of Childhood Obesity?

Discover, September 21, 2010.

A study of children has discovered a correlation between obesity and prior infection with a cold virus, called Adenovirus 36. While the link is fairly weak, the tantalizing research suggests a new front on the war on obesity.

The study participants included 124 children between the ages of 8 and 18. Of the 67 obese children involved in the study, 15 had signs of previous infection with the AD36 virus, in comparison with only 4 of the 57 non-obese children. The study was published in the online edition of Pediatrics.

The children who had been previously exposed to the virus (which was indicated by the antibodies to the virus present in their blood) were on average 50 pounds heavier than the non-exposed children. And even within the obese group, those that had been previously exposed to AD36 were an average of 35 pounds heavier. Read More >

Surprise breast cancer source

The Scientist, September 1 2010.

Some breast cancer tumors may not originate from stem cells as previously believed, according to a study published in the September 3rd issue of Cell Stem Cell. The discovery is an important step in the development of treatments for these cancers.

“Understanding the origins of these types of breast cancer is not only critical for developing preventative strategies against the disease but also for developing new targeted therapies,” said Matthew Smalley, a mammary cell biologist at the Breakthrough Breast Cancer Centre in London and lead author on the study. Read More >
