“Lior Shamir, a computer scientist who’s actively participated in efforts to increase participation in STEM fields, now wonders if she’s been on the wrong side.” The theme of those academic meetings has been rather consistent: we must reach out to those lost souls who chose to study the humanities or social sciences and show them…
“Kan kun være malet af en gal Mand!” (“Can only have been painted by a madman!”) appears on Norwegian artist Edvard Munch’s most famous painting The Scream. Infrared images at Norway’s National Museum in Oslo recently confirmed that Munch himself wrote this note. The inscription has always been visible to the naked eye, but the infrared images helped…
Some of Elon Musk’s stunts have caught my attention. He was involved in founding the company that became PayPal (which I use from time to time, to accept freelance payments and to pay other freelancers), and I can see a lot of people would benefit from the high-speed train systems he has advocated, but I…
It’s a bit of a stretch to call this Teddy Roosevelt quote “encoded,” but it’s still fun to notice. We’re told to be on the lookout for more surprises as the mission develops. Systems engineer Ian Clark used a binary code to spell out “Dare Mighty Things” in the orange and white strips of the…
New video from NASA’s Mars 2020 Perseverance rover chronicles major milestones during the final minutes of its entry, descent, and landing (EDL) on the Red Planet on Feb. 18 as the spacecraft plummeted, parachuted, and rocketed toward the surface of Mars. A microphone on the rover also has provided the first audio recording of sounds…
Today, February 18, 2021 at 20:44 UTC (3:44 p.m. Eastern US time), if all goes well, another robotic rover will land on the planet Mars. —Bad Astronomy
I noticed this meme a few days ago. I recognized the “friend of a friend who has insider knowledge” formula that makes people want to share a memes. I know better than to trust anonymous online sources that claim to have special knowledge, so I just re-read what the CDC says and moved on. Here…
The anti-maskers are right when they say masks aren’t 100% effective. The pro-face-touchers are right when they say not touching your face isn’t enough. The bar-hoppers and close-talkers and eaters-in-crowded-diners are right when they say social distancing alone won’t stop the spread of a pandemic. The “98.2% survival rate” crowd is right that most people…
Rewatching ST:TNG This flipside episode, told entirely from the viewpoint of a civilization on the verge of discovering warp drive technology, documents a visit from members of a federation of space-faring aliens who wear brightly colored pajamas. An ER team with serious forehead bumps admits a patient with serious head injuries. They are first confused,…
You may be surprised to learn that of the trio of long-awaited coronavirus vaccines, the most promising, Moderna’s mRNA-1273, which reported a 94.5 percent efficacy rate on November 16, had been designed by January 13. This was just two days after the genetic sequence had been made public in an act of scientific and humanitarian generosity…
I was thrilled as a middle-schooler to stay up late watching PBS coverage of science types poring over printouts of the images arriving from Voyager 1 and 2’s visits to Jupiter and Saturn in 79-81, and visits to Uranus and Neptune in the late 80s. The Star Wars and Star Trek movie franchises were in…
For more than 150 years, scientists have considered bird song to be an exclusively male trait, but female scientists have changed that. Americans often idealize scientists as unbiased, objective observers. But scientists are affected by conscious and unconscious biases, just as people in other fields are. Studies of birds’ vocal behavior clearly show how research approaches…
In the wake of the pandemic, the entertainment industry created a new position on set to help keep outbreaks at bay. […] The demands of the job are big: sanitization, testing, safety equipment and distancing. Cast and crew are split into different zones, based on the frequency of testing and ability to wear masks. The…
Bits and pieces from a news article that summarizes recent scholarly studies. Some moderately good news, and a reminder that increased testing means finding more cases, and finding them earlier, which means people get medical treatment sooner. (More testing means less suffering and fewer deaths. For those of us who care about such things.) Over…
I wish I had the time or energy to get out the telescope and camera, but I did go out for a walk in the neighborhood and got an eyeful of this in the sky.
From The Brookings Institution (non-profit, deeply sourced factual writing; has been accused of both conservative and liberal bias; is cited in Congress about equally by conservative and liberal politicians; leans a bit left in terms of loaded language): American institutions are not perfect, of course. We all should want to improve scientific practices, remove bias…
Those darned reporters. Always publishing newsworthy facts of national importance that powerful people would rather keep silent. When Hicks tested positive, she worried about others around her who might be infected, too, but the White House sought to keep that information from the public. Without Jennifer Jacobs, a dogged Bloomberg reporter who broke the story…
So negative! Why does the lying America-hating fake news media keep publishing stories that make Trump look bad? Where are the reports about superspreader events in the Obama White House? Where are the stories about Obama’s family members and staff ostentatiously refusing to take precautions that their own medical experts recommended that all Americans take?…
This is the end of the coronavirus pandemic. And this is how it could happen in the United States: By November 2021, most Americans have received two doses of a vaccine that, while not gloriously effective, fights the disease in more cases than not. Meanwhile, Americans continue to wear masks and avoid large gatherings, and…
Friday the CDC released updated guidelines that reflected recent scientific observations that the coronavirus is airborne and can transmit over a distance of more than six feet, as CNN reported. This morning the CDC reversed itself, removing the updated information. From the Washington Post: The agency had posted new guidelines suggesting the virus can…
