Quickies: Tardigrades, editing DNA, and “failed marriages”
- Angelina’s divorce shows how “failed marriages” are failing us – “With longer lives, people and their priorities change. If you can only count to living well until 40, then getting hitched at 25 means that your sense of self doesn’t have that much room to change. But today, says Pinsof, your sense of your “relational future” at 35 or 50 is way different than it was before the 20th century.” From Amy.
- The world’s hardiest animal has evolved a radiation shield for its DNA – Tardigrades: endlessly cool.
- Breaking taboo, Swedish scientist seeks to edit DNA of healthy human embryos – “Lanner is attempting to edit genes in human embryos to learn more about how the genes regulate early embryonic development. He hopes the work could lead to new ways to treat infertility and prevent miscarriages. He also hopes to help scientists learn more about embryonic stem cells so they can someday use them to treat many diseases.”
- The muddled link between booze and cancer – “The public health community is split among people who think alcohol has its benefits and those who caution against its risks. The WHO’s designation puts alcohol in the same category as processed meats and sunlight: They’re carcinogenic, but that label doesn’t tell you how much is how carcinogenic.”
