The Weight Of A Med Student's Subconscious Bias

Joe Palca — Thu, 23 May 2013 22:03:00 +0000

Quite a few medical school students have something against obese people, and most of those who have such a bias are unaware of it.

That's the conclusion of study appearing in the July issue of Academic Medicine. It was conducted at the Wake Forest School of Medicine in Winston-Salem, N.C.

Atop A Hawaiian Mountain, A Constant Sniff For Carbon Dioxide

Climate scientists have a good reason to want to get away from it all. To get an accurate picture of the amount of carbon dioxide in the Earth's atmosphere, you have to find places where the numbers won't be distorted by cities or factories or even lots of vegetation that can have a major local impact on CO₂ concentrations.

Starting in 1958, scientists from the Scripps Institution for Oceanography have been using an instrument on the top of the Mauna Loa volcano in Hawaii to measure CO₂ in the atmosphere.

Wake Up And Smell The Tuna? Sunrise At Honolulu's Fish Auction

If you are up at 5 in the morning in Honolulu and are wondering what to do, I have a suggestion: Head over to Pier 38 and watch the Honolulu Fish Auction. It's quite a scene.

Getting up at 5 may seem a bit extreme, but for recent arrivals to Hawaii from the East Coast of the mainland — as I was last Friday — the six-hour time difference makes waking up early easy, if not inevitable.

The auction takes place in a low-slung single-story building toward the end of the pier. At about 1 a.m., fishing boats start bringing in their catch.

Envisioning The Future With Cori Lathan

Computers were created to be useful tools, but all too often it's still a chore to get technology to do our bidding.

Corinna Lathan imagines a future that's no longer a chore, where computers understand our wants and needs so well that we don't even have to think about telling them what to do. She's an inventor who has started her own company, AnthroTronix, to make that kind of intuitive technology part of our lives.

Kepler Telescope Spots 3 New Planets In The 'Goldilocks Zone'

Joe Palca — Thu, 18 Apr 2013 19:26:00 +0000

Astronomers have found three planets orbiting far-off stars that are close to Earth-sized and in the "habitable zone": a distance from their suns that makes the planets' surfaces neither too hot nor too cold, but just right.

One of the three planets orbits a star with the prosaic name Kepler-69.

"Kepler-69 is a sun-like star," says Thomas Barclay, a research scientist at the Bay Area Environmental Research Institute who uses the Kepler space telescope, which is on a mission to search for Earth-lik

Wanna Play? Computer Gamers Help Push Frontier Of Brain Research

People can get pretty addicted to computer games. By some estimates, residents of planet Earth spend 3 billion hours per week playing them. Now some scientists are hoping to make use of all that human capital and harness it for a good cause.

Right now I'm at the novice level of a game called EyeWire, trying to color in a nerve cell in a cartoon drawing of a slice of tissue.

Cheesecake Factory, IBM Team Up To Crack The Code Of Customer Bliss

Consider the following entirely fictitious but totally plausible scenario:

A diner at the Kuwait City branch of The Cheesecake Factory restaurant chain complains to his waiter that the pickles in his Americana Cheeseburger (American and cheddar cheese, crunchy potato crisps, lettuce, tomato, grilled onions, pickles and secret sauce) had a funny texture.

Scientists Pass The Hat For Research Funding

When the X-ray was invented, people clamored to get one. Not for any medical reason, but just to see what was typically hidden inside their bodies.

Something like that seems to be happening with DNA sequencing technology. First it was companies offering to sequence people's genomes. Now it's learning all about your microbiome, the collection of microorganisms living on and in your body.

People's fascination with their inner workings may provide a new way for scientists to raise money for basic research.

Small Meals, Big Payoff: Keeping Hunger And Calories In Check

When presented with a tempting buffet of French food, not overeating can be a challenge. But a new study by researchers in Lyon suggests there are strategies that will help people resist temptation.

People trying to keep off excess weight are frequently told that it's better to eat small amounts of food frequently during the day, rather than the typical breakfast, lunch and dinner.

Drug Fulfills Promise Of Research Into Cystic Fibrosis Gene

Joe Palca — Wed, 02 Jan 2013 20:04:00 +0000

The promise of genetic medicine is beginning to be fulfilled, but it's been a long, hard slog.

Take the story of Kalydeco. It's designed to treat people with a lung disease called cystic fibrosis. While not quite a cure, the drug is extremely effective for some CF patients.

But the success of Kalydeco has been more than two decades in the making.

A good starting point for the story is Aug. 24, 1989. That's the day scientists from the U.S. and Canada announced the discovery of the gene associated with the disease.

The Quest For The Perfect Toothbrush

There are some consumer products where every year brings new innovations. Computers get faster, cellphones get lighter, cars get new bells and whistles.

It's easy to imagine why inventors are drawn to redesigning these products — the technology for making them is changing all the time.

But what about consumer products that have been around for a long time? For the toothbrush, the answer is a resounding yes.

According to the U.S. Patent and Trademark Office website, as of Christmas Day there were 138 patents with the word toothbrush in the title issued this year.

Building A Rover Of The Edible Kind

Joe Palca — Tue, 18 Dec 2012 20:59:00 +0000

The folks at the California Institute of Technology have built another Mars rover, but this one will never get to leave Earth. Not surprising, really, since it's made of gingerbread.

I first learned about the new rover from my colleague Nina Gregory at NPR West, who spotted it in LA Weekly's restaurant blog.

NASA Scientists 'Very Careful' With New Mars Data

Joe Palca — Mon, 03 Dec 2012 22:23:00 +0000

NASA is finally receiving data on Martian soil samples from Curiosity, its rover currently traversing the red planet. The results from the soil samples hint at something exciting, but rover scientists are making very sure not to raise expectations.

NASA had always planned to present early results from the mission this week at a press conference.

Signs Of Life On Mars? Not Exactly

Joe Palca — Sun, 02 Dec 2012 20:30:00 +0000

The director of NASA's Jet Propulsion Laboratory said last week that preliminary data showed the possibility that the agency's Mars Science Laboratory – the six-wheeled rover that landed on Mars in August — had found signs of carbon-containing molecules.

According to a JPL news release, however, there will be no major announcements Monday, when scientists take part in a news conference at the annual meeting of American Geophysical Union.
