Everyone can appreciate the value of a good night's sleep. But did you know that a lack of sleep can have real consequences for your health? QUEST investigates how sleep affects our minds and bodies and uncovers why some people are genetically programmed to need less sleep than others.
Nearly all of us have had the experience of waking up and feeling as though the restorative, rejuvenating effects of a good night's sleep had passed us by.
Thanks to stem cells and other cutting-edge technologies, doctors hope they may one day be able to restore sight to people who were born without it, or lost it, later in life. But a rare case here in the Bay Area suggests that curing blindness may be more than meets the eye.
When Mike was three years old, he opened up a jar containing an explosive chemical that the miners had left behind. The accident left him nearly blind. Forty-two years later, doctors fixed one of his eyes in a series of two procedures.
This month, truckers at the Port of Oakland face new rules on diesel rigs.The rules call for expensive filters that cut down the amount of soot the trucks spew out. Many truckers say they can't afford the new gear, especially amid a recession. But treating the health effects of diesel pollution may be much more expensive.
People often think about certain versions of a gene as either good or bad. One that leads to depression is bad while one that protects you from HIV infection is good. For most genes this is almost certainly too simplistic a view. Many versions of genes can be good or bad depending on your situation.
Time recently had a great article on helicopter parents. These are the parents who hover around their kids, protecting them from any harm. They are undoubtedly doing this to ensure their kids’ success in life. I don’t want to get into the plusses and minuses of this parenting style…to each his own. What I do want to do is to warn them away from a new genetic testing company that seems designed to target them.
People with pseudobulbar affect — a neurological condition common in patients with Lou Gehrig's disease — have overwhelming emotions at inappropriate times: They laugh uncontrollably at funerals, cry even when they aren't sad. Scientists at UC San Francisco believe that by putting these people into MRI scans, they can learn more about how emotions are created and controlled in the human brain — and what happens when those systems break down.
If a DNA testing company gets bought out, what happens to their customers' DNA? Image by Molly Eyres. / CC BY 2.0 One niggling worry I had when I decided to get some genetic testing from 23andMe was what would happen to my DNA if the company failed. By all accounts, 23andMe is a very […]
Each October, within Breast Cancer Awareness Month, my friends and I get into a flurry organizing and putting on Beats for Boobs.
"Mysteries of DNA" image courtesy Mark H. Adams. Full-size version. As anyone who follows this blog knows, I recently took a 23andMe genetic test and have been blogging about it ever since. Today I thought I would focus on one of the fun parts of the service: traits. Lots of our traits are at least […]
What can genetic testing tell you? A while back I took a 23andMe genetic test that looks at over 600,000 different spots on my DNA. The last few blogs I have been going over my genetic test results with an eye on how useful they are. And how well the results are explained. Last blog […]
Luis Medellin and Karl Tupper set up a drift catcher in Lindsay, CA. My radio story on pesticide drift looks at how residents in the citrus town of Lindsay are monitoring pesticides in the air and in their bodies. They are using a device called a Drift Catcher, modeled after technology used by the California […]
