Printed in space

Wow. I knew the ISS now had a 3D printer, because it’s much more practical – that is, possible – to make needed equipment on board than it would be to pack all potentially needed equipment, but even knowing that, this story is very cool.

For the first time ever, hardware designed on the ground has been emailed to space to meet the needs of an astronaut. From a computer in California, Mike Chen of Made In Space and colleagues just 3D-printed a ratcheting socket wrench on the International Space Station. “We had overheard ISS Commander Barry Wilmore (who goes by “Butch”) mention over the radio that he needed one,” Chen writes in Medium this week. So they designed one and sent it up. [Read more…]

Yes that’s right, exactly like this

Siiiiigh.

At Wired, Elena Glassman, Neha Narula and Jean Yang tell us what happens when women in a STEM field talk about…oh, whatever.

“We’re 3 female computer scientists at MIT, here to answer questions about programming and academia. Ask us anything!” we wrote for our Reddit Ask Me Anything session last Friday. And then, boom:

“WHY DOES IT MATTER THAT YOU’RE FEMALE?”
“WHY DID YOU PUT GENDER IN THE TITLE?”
“WHY SHOULD YOUR GENDER MATTER IF YOU’RE TALKING ABOUT RESEARCH?”

More poor Muslims than rich westerners

Oh look. Looky there. A headline on a Guardian Comment is Free post by Ben Doherty –

Pakistan attack reveals the truth about terrorism: it kills more poor Muslims than rich westerners

Golly gee, that’s exactly what I was saying in that post on Sunday that got so many people in such a (mostly fake) rage. How shockingly ideological to make that point! Why shouldn’t terrorism kill more poor Muslims than rich westerners? Why even mention it? It’s political correctness run mad. [Read more…]

The procedure involves slicing through the cartilage and ligaments

And speaking of doing horrible things to people…The Guardian reports another one of Ireland’s grim secrets.

“Mary” was delighted to be pregnant at 23, but she was in labor for a long time, and they got worried about her heartbeat, so they called in the doctor.

When the doctor arrived, he did something Mary cannot forget. “They gave me gas and air and an injection, and took me to another room, where they tied my legs up on each side,” she recalls. “There were two nurses on each side of me. I saw this doctor at the end of my bed with a big, long silver thing. They made a hole in your private parts, and he inserted this silver thing up and cut the pubic bone and pushed it over to widen your pelvis for you to deliver your baby yourself.” [Read more…]

The next thing we knew, she was on fire

Yesterday the Telegraph reported some heart-breaking details of the slaughter at the army school in Peshawar. Be warned: they’re not happy reading.

The Taliban attackers reserved particularly horrific deaths for the adults, pouring fuel over at least three and setting them alight and killing the head, Tahira Qazi, with a hand grenade.

“Our principal showed extreme bravery,” Wasif Ali, a grade six pupil, said from his bed at the Lady Reading Hospital, where he was being treated for abdominal and head injuries. “She wasn’t afraid even when the militants were firing shots.” He said that as the firing started, she rushed from classroom to classroom, shouting at those inside to lock themselves in. Other pupils said she was trying to console them as well as protect them. [Read more…]

Self-appointed experts

NPR did a blog post about Vani Hari aka “Food Babe” the other day.

…as her profile grows, so too do the criticisms of her approach. Detractors, many of them academics, say she stokes unfounded fears about what’s in our food to garner publicity. Steve Novella, a Yale neuroscientist and prominent pseudoscience warrior, among others, has dubbed Hari the “Jenny McCarthy of food” after the celebrity known for championing thoroughly debunked claims that vaccines cause autism.

Hari is a self-styled consumer advocate and adviser on healthful eating. [Read more…]

Arctic feedback cycle

Here’s a disquieting press release from NASA:

NASA Satellites Measure Increase of Sun’s Energy Absorbed in the Arctic

NASA satellite instruments have observed a marked increase in solar radiation absorbed in the Arctic since the year 2000 – a trend that aligns with the steady decrease in Arctic sea ice during the same period.

While sea ice is mostly white and reflects the sun’s rays, ocean water is dark and absorbs the sun’s energy at a higher rate. A decline in the region’s albedo – its reflectivity, in effect – has been a key concern among scientists since the summer Arctic sea ice cover began shrinking in recent decades. As more of the sun’s energy is absorbed by the climate system, it enhances ongoing warming in the region, which is more pronounced than anywhere else on the planet. [Read more…]
