The Great Cancer Cell Mix Up

The Great Cancer Cell Mix Up

Under a microscope many cancer cells look the same. And since cell lines used in cancer research are anonymous, often shared informally between labs, the only way to definitively know where they came from is with DNA. But many scientists don't do this.

Science on the SPOT: Shadows and Spiders– A Secret Cave in California

Science on the SPOT: Shadows and Spiders– A Secret Cave in California

The rural foothills along the Santa Cruz County Coast hold an ancient secret. Deep below the redwoods, White Moon Cave extends for nearly a mile — making it one of the longest caves in California. But few people have ever been in it. Join the KQED Science team as we squeeze through the narrow clandestine entrance, and meet the uncanny cave inhabitants to bring new light to this hidden realm.

Turkey Trouble: Genetics Gone Too Far?

Turkey Trouble: Genetics Gone Too Far?

No, this isn’t a blog about genetically modified organisms — that has been argued enough lately! Instead, in honor of Thanksgiving, I want to talk about regular old selective breeding and the monsters it can create.

Trophy Hunting: For the Love of Blood and Money

Trophy Hunting: For the Love of Blood and Money

Trophy hunters routinely pay thousands of dollars for the chance to kill big game like caribou, moose, black bear and especially grizzly bear. Trophy hunting narratives boast a love of nature. But some sociologists find a different story.

New Clues to Our Ancestors' Mobility

New Clues to Our Ancestors' Mobility

Australopithecus afarensis (the species of the well-known “Lucy” skeleton) was an upright walking species, but the question of whether it also spent much of its time in trees has been hotly debated for 30+ years, partly because a complete set of A. afarensis shoulder blades has never before been available for study.

Frankenstein vs. Godzilla:  What’s in Your Cereal Bowl?

Frankenstein vs. Godzilla: What’s in Your Cereal Bowl?

In all of the recent discussion about genetically modified (GM) foods here in California, we’ve overlooked regular foods and how new traits are found (or created) in them. There isn’t usually a monk lovingly breeding peas in the Austrian countryside somewhere. Instead, more often than not, there is someone blasting a seed with radiation and/or harmful chemicals.

Playing Whack-a-Mole with Flame Retardants

Playing Whack-a-Mole with Flame Retardants

Countless consumer products sold in California contain a flame retardant flagged as a possible carcinogen nearly 35 years ago. As of this week, finally, they must carry a warning that the chemical causes cancer. But is it enough when manufacturers simply replace one toxic chemical with another?

Creepy Yet Compelling: Blood Vessels Blown in Glass

Creepy Yet Compelling: Blood Vessels Blown in Glass

Halloween means time for gore! Blood, bones, brains and more! Severed fingers, severed toes, eyeballs and organs galore! But how accurate are all these loose bits of human anatomy in our front yards, costumes and punch bowls? Can we use that skeleton in the corner to bone up for a biology exam–or are we missing out on a tremendous opportunity to learn medical science?

Science Behind Vampire Myths

Science Behind Vampire Myths

Why have people around the world always been fascinated by vampires? Did vampire tales begin as a way to explain frightening phenomena actually witnessed? Although there is no scientific evidence for vampires, there is some scientific basis for vampire folklore.

Be HEARD: A Rare Disease Science Challenge To Find Cures

Be HEARD: A Rare Disease Science Challenge To Find Cures

Curing or even finding treatments for rare diseases is hard. Not necessarily because these diseases are any more complex than more common ones. It has more to do with the fact that there is very little profit to be made in helping people with these diseases.

Vaccine Waivers, Informed Consent and Public Health

Vaccine Waivers, Informed Consent and Public Health

Starting in 2014, California will require parents to see a health practitioner to learn the risks and benefits of vaccination before opting out of the state's immunization requirements. Public health officials hope that when parents learn the difference between science-based evidence and the uninformed myths so prevalent online and in the mainstream media, they'll decide to protect their children from the real risks of infectious disease, rather than worry about unfounded theoretical risks.

Saving Bighorn Sheep, One Mural At a Time

Saving Bighorn Sheep, One Mural At a Time

Sierra Nevada bighorn sheep are animals worth seeing. With their bright white rumps and the rams' remarkable headgear, they bound and leap over seemingly impassable alpine terrain. But you may have a tricky time spotting one–there are only about four hundred in existence.

Who is Qualified to Decide Scientific Matters?

Who is Qualified to Decide Scientific Matters?

In November, California voters need to decide whether or not GM foods should be labeled as such. They are making this decision even though a recent study shows that 49% of the people surveyed think that GM foods have genes whereas regular foods do not. Is this any way to run a democracy?

Think Pink? I’d Rather Raise a Stink

Every October, high-profile outlets from Ace Hardware to the NFL sell pink products to raise awareness and money for Breast Cancer Awareness Month. Critics of "pinkwashing" urge consumers to ask just how much of that money goes to support breast cancer programs–and challenge us to move beyond awareness to action.

Illustrating Science: Translating Knowledge Into Pictures

Allison Bruce has a wonderful job: she spends all day making pictures for scientists. Bruce started out in science herself, earning a chemistry degree from UC Davis. After college, she worked in an environmental lab, but she didn't enjoy it and turned to art classes "to keep from losing my mind," she says.
