My greatest genetic engineering fear: that we'll try to erase our flaws
I still remember the look of profound pity on the clerk’s face when I asked where the pregnancy tests were. I’m sure it all looked so obvious: the young woman standing with a young man in a dollar store in a college town. We walked in silence to the family planning section, but then I realized my mistake.
What a strange case of scientific déjà vu showed us about the dangers of plastics
Photo by freestocks.org on Unsplash New research shows that BPA-free plastic might still be harmful March 15, 2019 Plastic is everywhere: water bottles, dental sealant, the odd floating trash island. Over the years, researchers have raised the alarm about how chemicals from plastics might affect human health, often focusing on one chemical in particular: bisphenol A (BPA). BPA is used to make a hard, clear type of plastic called polycarbonate.
This is how the light from your phone breaks your internal clock
It's not just sleep: circadian rhythms influence your metabolism, circulation and psychology, too November 14, 2018 On December 30th, 1882, at twenty minutes past eight, the first electric streetlights were turned on in Los Angeles. The few lamps, placed in the center of town, cast a gentle glow that was compared to “the full moon on snow”.
What is genetic modification?
In the 1970s, the US was staring down the barrel of an insulin shortage. Diabetes, once a virtual death sentence, could be easily controlled with injections of insulin derived from the pancreas glands of pigs and cattle. But making just one pound of pure insulin required over 20,000 animals, and as the demand for insulin rose, manufacturers worried that they wouldn’t be able to keep up. The solution seemed like something straight out of science fiction.
What is genetic modification?
It's surprisingly difficult to pin down a conclusive definition July 30, 2018 In the 1970s, the US was staring down the barrel of an insulin shortage. Diabetes, once a virtual death sentence, could be easily controlled with injections of insulin derived from the pancreas glands of pigs and cattle.

Like dogs? They're genetically modified organisms (from a certain point of view)
Pull a product from the shelf of your local grocery store and you may find a label proudly proclaiming it "GMO-free." Those who support the labeling of products containing GMOs, short for genetically modified organisms, argue that people deserve to know what they're putting in their bodies. But opponents argue that these labels are essentially meaningless – the latest episode in the great American tradition of health food hoaxes.
The Incredible Evolution Of Periods – The Establishment
I n Naturalis Historia, the Roman naturalist Pliny the Elder wrote that period blood has the power to stop whirlwinds, kill bees, and drive dogs mad. If you feel compelled to chuckle, keep in mind that nearly 2,000 years later, menstruation is still shrouded in myth, taboo, and beliefs that are nearly as bizarre as what ‘ol Pliny was peddling. In fact, the actual science of why people have periods is almost stranger than the myths.
Climate change will cause food shortages. We should use genetic engineering to prevent them
Even small changes in temperature can have massive impacts on crop productivity. In the United States, a single degree of warming is expected to decrease corn yield by 10 percent. Worldwide, one degree of warming is expected to decrease crop productivity by 3-7 percent. Making matters worse, at the same time as crop yields are expected to decrease, the global population will continue to rise.
Feeding the world as the climate changes will depend on genetic engineering
CRISPR and other tech could help us produce more food, but only if we drop the GMO stigma August 30, 2017 Even small changes in temperature can have massive impacts on crop productivity. In the United States, a single degree of warming is expected to decrease corn yield by 10 percent. Worldwide, one degree of warming is expected to decrease crop productivity by 3-7 percent. Making matters worse, at the same time as crop yields are expected to decrease, the global population will continue to rise.
How scientists use light to manipulate cells with the flick of a switch
Optogenetics lets us probe the inner workings of cells with unprecedented precision August 14, 2017 Imagine how complicated it is to build an entire human body starting from a single cell. To get from one egg cell to the many trillions of cells currently making up your body, you have a lot of growing and dividing to do. Certain cells must know to become muscle – others, bone. And just as important as knowing when to grow is knowing when to stop.
