Exoplanet Extravaganza

“It isn’t only the beauty of the night sky that thrills me. It’s the sense I have that some of those points of light are the home stars of beings not so different from us, daily cares and all. who look across space with wonder, just as we do.” -Frank Drake What is it that…

As more and more exoplanets (at first) and earth-like exoplanets (eventually) have been discovered, the way thy are described to us has become increasingly sophisticated. Below are embeds of diverse video descriptions that have been very quickly developed and distributed given the freshness of this latest scientific discovery. Note that the practice of very clearly…

Exoplanet hunters have discovered a cache of rocky planets orbiting a star called TRAPPIST-1 only forty light-years away. Compared to our sun, TRAPPIST-1 is tiny, and all its planets orbit closer than Mercury orbits Sol. But three of them are still in the Goldilocks zone that could be just right for life, and all seven planets could theoretically hold liquid water. While Ethan Siegel introduces the neighboring star system with spectacular illustrations from NASA and ESO, Greg Laden says that the practice of saying these images are artistic interpretations "has largely fallen by the wayside." Instead, scientific outreach has turned to storytelling in order to capture public interest.

Life Science

A new study shows that globally, spiders consume 400-800 million tons of prey each year. That’s roughly more than double the amount of fish and meat that humans consume. Impressive…yet creepy at the same time. I suppose we should thank them for their pest control efforts. Sources: M Nyffeler, K Birkhofer. An estimated 400–800 million tons of prey…

Monarchs and Milkweed: A Migrating Butterfly, a Poisonous Plant, and Their Remarkable Story of Coevolution by Anurag Agrawal is a fantastic, readable, scientifically rich, detailed monograph about – you guessed it – the monarch butterfly and the milkweed plant. The monarch butterfly begins a springtime northward migration by flying a good ways north, where females…

Water bears, aka tardigrades, are resilient little creatures. These microscopic animals can survive both freezing and boiling temperatures, radiation, high pressure, starvation, the vacuum of space and even desiccation. This last ability caught the attention of a team of researchers interested in how they are able to survive for years despite being completely dried out, an ability known…

Physical Science

I mentioned in passing in the Forbes post about science funding that I’m thoroughly sick of hearing about how the World Wide Web was invented at CERN. I got into an argument about this a while back on Twitter, too, but had to go do something else and couldn’t go into much detail. It’s probably…

“The creation of something new is not accomplished by the intellect but by the play instinct acting from inner necessity. The creative mind plays with the objects it loves.” -Carl Jung 13.8 billion years ago, the Universe as we know it came into existence. Today, the part we can observe is 46 billion light years…

“For me, it is far better to grasp the Universe as it really is than to persist in delusion, however satisfying and reassuring.” -Carl Sagan The President of the United States just released his proposed budget for the next fiscal year, and there are some big losers in the scientific world. The EPA, the NIH,…

Media Matters has an amazing and rather depressing report out on the way broadcast media in the US covered climate change. I’m going to give you a handful of bullet points that reflect only some of the results of this detailed study, then you go read it. Bottom line: Coverage in 2016 was a fraction…

The Great Persuasion: Reinventing Free Markets since the Depression is a history by Angus Burgin of… well, you can read the potted summaries there, none are quite exact, I’ll off you another gross simplification: of the transition from Hayek as prophet-in-the-wilderness to the triumph of Friedman. So, this post is yet more politics, or economics,…

You all know about this: It is being said that the OK sign is used to indicated “White Power” and this use has been spotted among politicians and celebrities everywhere. Is this real? I don’t know. Is it a valid symbol for “White Power”? Certainly not. The problem with the white power symbol is that…

California farmworkers living in fear of deportation; Ontario health care workers call on officials to address violence in the workplace; West Virginia legislators consider dramatic loosening of mine safety standards; and thousands of workers get ready to strike on May 1.

“Qualitative research” seems largely to mean “anecdotal material with no statistical representativity”. I’m starting a support group for people who think the novel American Gods is not great, not bad, not particularly memorable. Woah-ho, dude. Lucid dreaming is when you train yourself to a) know that you’re dreaming, b) direct events in the dream. This…

A bunch of people in my social-media feeds are sharing this post by Alana Cattapan titled Time-sucking academic job applications don’t know enormity of what they ask. It describes an ad asking for two sample course syllabi “not merely syllabi for courses previously taught — but rather syllabi for specific courses in the hiring department,”…

Everyone knows that you never say the name “Voldemort” because it gives him power. Like this: And perhaps for this reason, many non-deplorables wish to avoid using the name of Trump. I can understand their position, and I respect their point of view. Having said that, they are totally wrong, of course. Trump isn’t just…

I’ve written before about how our vaccination rate here in Michigan are…suboptimal. Indeed, a couple of years ago, health officials were so alarmed at the increases in personal belief exemptions to school vaccine mandates that a new regulation was instituted that require parents seeking nonmedical exemptions to school vaccine mandates to travel to an office…

Out of southern California, comes a lesson that something as seemingly benign as turmeric can kill when weaponized in the hands of a quack.

The grieving widower killed the naturopath who treated his wife with cancer after telling her that “chemo is for losers.” Where I see a tragedy, naturopaths see an opportunity to argue for naturopathic licensure.

Brain & Behavior

Darwin’s Unfinished Symphony: How Culture Made the Human Mind is a new book on cultural evolution in humans from a biological perspective. This is an interesting book and a good book, and I recommend it, but I need to add a strong caveat. The author could have made a more compelling argument had he more…

via GIPHY A new article published in the Proceedings of the National Academy of Sciences presents the discovery of a species of frog with fluorescence. The South American polka dot tree frog, aka Hypsiboas punctatus is already rather cute under normal light. But when exposed to UV light, this frog really shines. It gets its glowing personality from…

I had a bunch of quarters in my pocket. About six dollars worth, along with a couple of one dollar coins. I pulled all the change out of my pocket and placed it on a desktop. I walked away. A few minutes later, I went to grab the coins so I could bring them to…

Researchers studying komodo dragons (Varanus komodoensis) at George Mason University discovered 48 previously unknown peptides in their blood that might have antimicrobial properties. Their findings were published in the Journal of Proteome Research. For the largest lizard, these peptides may help prevent the animals from getting infections from their own saliva, which is host to at least 57 species…

This is much better than the one you’ve already seen.

Drones are so early 20th century: That doesn’t actually look too hard to make. The only tricky part is how to attach it to the monkey.

OK, I admit, Friday Fun a few days late… In any case, last Friday marked the 20th anniversary of the premiere of Buffy the Vampire Slayer. Yes, March 10, 1997 marked the very first episode of one of the greatest TV shows of all time, and certainly my personal favourite. Although I didn’t start watching…

In 2015, the U.S. Environmental Protection Agency released a report finding 457 fracking-related spills in eight states between 2006 and 2012. Last month, a new study tallied more than 6,600 fracking spills in just four states between 2005 and 2014. But, as usual, the numbers only tell part of the story.

My library’s Hackfest was yesterday so I’m feeling kind of burnt out today. Today’s linked post cheers me immensely, in a side-eye, gallows humour kind of way. This recent Retraction Watch post is funny and you should read the whole thing: Got “significosis?” Here are the five diseases of academic publishing. Significosis Neophilia Theorrhea Arigorium…

President Trump’s nominee for Labor Secretary provided a peek during his confirmation hearing on his approach to running the Labor Department. Several things he said made me ask myself: “will employees at the Labor Department challenge Alex Acosta to keep his word on that?”
