This is a drawing of what the edge of the solar system might look like, as envisioned by plasma physicist Merav Opher. One of the few women in this field, Opher is also one of the top scientists, of any gender, studying what happens at the edges of space. John Rennie has written a great profile of Opher and her work. You really should read it. I like Rennie's work a lot. He's one of those amazing writers who can make abstract, theoretical physics feel as immediate, intense, and important as it actually is. To wit:
“The edge of the solar system” is more than a turn of phrase. A tenuous, invisible wind of ionized gas billows off the sun at a million miles per hour, carrying with it the sun’s magnetic field. It does not radiate out infinitely: far beyond Pluto’s orbit, this solar wind abruptly slams into the thin interstellar medium and the scattered gaseous remnants of exploded stars. That border defines what astronomers call the heliosphere.
Just a few years ago, Opher played a key role in explaining why the heliosphere is unexpectedly lopsided and off-kilter. Now an assistant professor in Boston University’s astronomy department, Opher is interpeting data that suggests that part of the heliosphere’s edge may be a churning magnetic froth, which could have broad implications for astrophysics.

Scott Pruitt, the Trump administration’s top environmental official, privately met with the CEO of Dow Chemical just before reversing the EPA’s efforts to ban a widely used Dow pesticide. Multiple scientific studies showed chlorpyrifos can damage the brains of children. Today’s Associated Press story is a clear case for why the Environmental Protection Agency and […]
The YouTube channel HooplaKidzLab demonstrates some awesome science experiments you can try with your kids this summer. Here’s another video from the channel about how to make a robotic arm out of popsicle sticks:
Scientists discovered this new species of “glass frog” in Ecuador’s Amazon lowlands. Hyalinobatrachium yaku’s belly is so transparent that you can clearly see its kidneys, bladder, and beating heart. From Science News: Yaku means “water” in Kichwa, a language spoken in Ecuador and parts of Peru where H. yaku may also live. Glass frogs, like […]
Despite the upfront cost, electric toothbrushes are much better at removing plaque than those freebies from the dentist’s office. For those who struggle to fill the American Dental Association’s recommended two minutes of brushing time, or anyone with limited dexterity, a sonic toothbrush can give your oral care routine a boost.To keep your chops healthy […]
Learning a new language will give your resume an upgrade, sure, but it will also provide a huge cognitive boost for mental tasks outside of translation and conversation. Bilingual brains have been shown to be better at handling multiple concurrent tasks, and gaining fluency in a new tongue is an amazing way to improve memory, […]
If you struggle to get a good night’s rest, consider replacing your pillows before dropping hundreds on a new mattress. You can give your tired neck a break with a 2-pack of memory foam pillows, available now in the Boing Boing Store.Each of these pillows is stuffed with cooling polyurethane foam that molds to your […]
