Why I Do Science: Danielle Reed

Why I Do Science: Danielle Reed

If you can't abide Brussels sprouts and broccoli, your genes may be to blame. Geneticist Danielle Reed of the Monell Chemical Senses Center in Philadelphia studies differences in our perception of taste and smell. A small blip in DNA might determine if you're bitter blind or have a sweet tooth.

Sniffing Out Mr. Right

Sniffing Out Mr. Right

Biology may have made it so that women prefer the smell of men with different immune systems from their own. Disturbingly, the pill may turn this on its head so that women like the way men with similar immune systems smell.

Will He Have My Nose?

I get these kinds of questions all the time. And except for a few traits, I have to pretty much say I don’t know.

Sequencing Within Reach

Sequencing Within Reach

The cost of figuring out what someone’s DNA looks like is dropping like a stone. For casual consumers, though, affordable DNA sequencing can be less than useful. In fact, it might even make a difficult situation worse.

Turning Chickens into Dinosaurs

Turning Chickens into Dinosaurs

If we are ever going to resurrect dinosaurs, it probably won't be like in the movie Jurassic Park. Instead, we'll have to throw evolution into reverse and turn a bird back into a dinosaur.

How Neanderthal are You?

Graduate students at Stanford have created a tool called the Interpretome that lets you plug in your genome so you can figure out how Neanderthal you are.

New Study Suggests Autism More Tightly Linked To Environment Than Genetics

New Study Suggests Autism More Tightly Linked To Environment Than Genetics

The scientists estimate that environmental factors common to twins explains 55% of susceptibility to autism, whereas genetics accounts for only 37%.

Patient-Specific DNA Sequencing Finally Paying Off

Patient-Specific DNA Sequencing Finally Paying Off

Here Dr. Starr talks about three patients who have dramatically improved lives because scientists sequenced their DNA and correctly interpreted the results. The dream of helping individual patients using data from the human genome project is finally being realized.

The Cloud in the Silver Lining

The Cloud in the Silver Lining

There are no free lunches in genetics. Having a certain version of a gene may protect you from one thing, but make you susceptible to another.

Osama’s Sister’s Brother

Osama’s Sister’s Brother

Scientists could definitely get DNA results from Osama bin Laden in less than 24 hours. And they could conclude with high certainty that the man killed was Osama bin Laden.

Better Left Unknown?

Better Left Unknown?

Just because we can find out about some of our genetic information, should we? Even though the results are often not very useful or even very informative, they can sometimes be a real burden.

DNA Diving for Alzheimer’s

DNA Diving for Alzheimer’s

I was able to figure out my APOE status and so one of my key risk factors for developing late onset Alzheimer's from my 23andMe test even though 23andMe doesn't officially report any results for Alzheimer's.

Missing Gene Suggests Rodents Aren't The Best Model For Diabetes Research

Missing Gene Suggests Rodents Aren't The Best Model For Diabetes Research

Rodents and other mammals might not be ideal for studying type 2 diabetes because of a gene that was deleted from the human genome millions of years ago.

Tracing Bad (and Dangerous) Internet Science

A dangerous rumor has been spreading across the web that people with Rh negative blood are resistant or even immune to getting AIDS. They’re not. This is the “everyone is an expert” ethos of the web at its worst.

Reporter's Notes: Backyard Seed Banks

Reporter's Notes: Backyard Seed Banks

Today, most backyard gardeners opt for buying seed packets or seedlings at the garden store. But a handful of Bay Area groups are working to create local seed saving networks, where local gardeners can learn to save seeds and share them.
