From there I headed to a lively discussion about the ethics of gene editing. I found one speaker’s comparison of IVF treatment and gene therapy very compelling. I next found myself listening to Daniel Nocera talk about the chemistry behind his artificial leaves that can turn sunlight, water, and carbon dioxide into fuel. I had to pull on all of my old high school chemistry lessons but I followed the discussion enough to be very impressed with the idea.
I especially enjoy the astronomy panels at every AAAS meeting, and usually come away counting down the months until a favored project launches. This year I was introduced to a coming exploration of Europa, one of Jupiter’s moons. Europa has an ocean over a rocky sea bed that is covered by a thick sheet of ice. Those rocks and water make it a good candidate for having some sort of life. NASA is planning for 20 days of battery life on the surface while carrying 42 kg of scientific instruments. The mission is currently planned for 2024–25.
With my head full of space dreams, I found a seat at Naomi Oreskes’s Plenary lecture titled “The Scientist as Sentinel” and listened to her history of scientists as political activists. I was thinking about the good timing of that lecture as I followed a group of young scientists out into the hallway and heard them making plans for the protest on Sunday.
