On Aardvarchaeology, Martin Rundkvist tells the story of a 14-year old Swedish Muslim girl who also happens to be very good at karate. Recently this young woman was disqualified from a tournament because she wears a veil and the rules state "that the umpire needs to be able to watch for damage to…
On Uncertain Principles, Chad Orzel counts up toward the birthday of that most holy of men: Sir Isaac Newton. Each day Orzel will (hopefully) unveil a new gem that didn't make it into his exciting new book. On Day 1, Chad wrote about the apocryphal moment of inspiration—in a bathtub—that led the…
On Pharyngula, PZ Myers criticizes a stirring new short film imagining humanity's presence on the far-flung worlds of our solar system. PZ writes, "There’s nothing in those exotic landscapes as lovely and rich as mossy and majestic cedars of the Olympic Peninsula, or the rocky sea stacks of the…
In a phenomenon known as Peto's paradox, large mammals do not develop cancer more often than small mammals, despite having more cells that could go haywire. On Life Lines, Dr. Dolittle writes "Some researchers suggested that perhaps smaller animals developed more oxidative stress as a result of…
"Death is the only wise adviser that we have. Whenever you feel, as you always do, that everything is going wrong and you're about to be annihilated, turn to your death and ask if that is so. Your death will tell you that you're wrong; that nothing really matters outside its touch. Your death will…
A hot work environment killed at least 13 people in 2012 and 2013 (not counting cases from nineteen states, including California, that operate their own OSHA programs). On The Pump Handle, Celeste Monforton writes "the report shows the diversity of jobs and situations in which workers are at risk…
As an unprecedented outbreak of Ebola crosses borders in West Africa, people are asking new questions about the virus and its potential to turn into a global pandemic (hint: it's not gonna happen). Greg Laden writes "The disease is too hot to not burn itself out, and it has no human reservoir.…
Only 1% of the human genome codes for proteins, which might make you wonder what the rest of the nucleotide sequence is good for. In 2012 the Encyclopedia of DNA Elements (or ENCODE) announced that a full 80% of the genome played a biochemical role, interacting with proteins in some way. But a new…
Like Rocket—a genetically engineered, cybernetically enhanced raccoon—Guardians of the Galaxy is a strange beast. Wanting to make a little cash, Rocket and his talking tree-buddy Groot try to collect a bounty on that guy from Parks and Recreation (and Zero Dark Thirty [Chris Pratt]). But the human…
On Significant Figures, Peter Gleick examines the rather relaxed attitudes of some Californians to an extreme drought fostered by three years of dry weather. Gleick writes “reservoirs are at record low levels. Deliveries of surface water to some farmers are lower than at any time in recent…
With 2001 in the rear-view mirror, there have been no little green men, no meal-replacement pills, no flying automobiles, no space odysseys. But as big-budget plans to model the human brain prove, proponents of artificial intelligence remain hopeful. In its most literal sense, AI exists already:…
As our planet makes more and more noise, we can't help but wonder why no one is paying attention. Are we alone in the universe? Or alone in our desire to discover new worlds? PZ Myers says "Spaceship building is never going to be a selectively advantageous feature — it’s only going to emerge as a…
When a parent chooses not to vaccinate their child, they put many other people at risk. Some infants cannot be vaccinated due to medical complications, and even fully-vaccinated people are not always fully protected. Jessica Parsons tells the story of baby Finn on Aetiology, who was diagnosed with…
Perovskite solar cells can not only emit light, they can also emit up to 70% of absorbed sunlight as lasers.
Critical signaling molecules can be used to convert stem cells to neural progenitor cells, increasing the yield of healthy motor neurons and decreasing the time required to grow them.…
Scientists use a 'gene gun' to insert a gene from a flowering plant called rockcress into the cells of wheat seeds. The genetically modified wheat became more resistant to a fungus called take-all, which in real life can cause "a 40-60% reduction in wheat yields."
T-cells from six HIV+ patients…
For the first time, researchers have transformed induced pluripotent stem cells (iPSCs) into specialized bladder cells. Meanwhile the development of iPSCs from normal cells has been shown to depend on two proteins necessary for the induction of a glycolytic state. In order to make iPSCs,…
Do environmental factors such as toxins contribute to autism? On Respectful Insolence, Orac looks at a new study which found a correlation between birth defects and the eventual development of autism. Orac says this correlation has already been demonstrated, along with "autism and exposure to…
Testing behemoth ETS announced a re-revised SAT for 2015, trying to stay one step ahead of its rival and the legions of teenagers who game standardized tests. Suggesting the vocabulary section was intended as "a proxy test for wide reading," Chad Orzel says memorizing obscure words is "dumb…
It's been a frigid winter in much of the United States, but Greg Laden notes that the country covers only 1.5% of the Earth's surface, and overall the planet just experienced the fourth-warmest January on record. Meanwhile global warming denialists are resorting to every rhetorical trick in…
Solar cells made with bismuth vanadate achieve a surface area of 32 square meters per gram. This compound can be paired with cheap oxides to split water molecules (and make hydrogen) with record efficiency.
Short-term geoengineering could postpone global warming, only to have it happen…
Warm weather at the Winter Olympics played a major part in the $51 billion extravaganza. Greg Laden calls the Sochi games more of a "Fall Olympics" as competitors bit the slush on the slopes and the half pipe. At the Extreme Park, casualties among women outnumbered casualties among men by nearly 3…
Researchers observed tiny voids forming in silicon used for solar panels; these voids provide physical evidence of the Staebler-Wronski effect, "which reduces the solar cell efficiency by up to 15 percent within the first 1000 hours."

The story starts off predictably enough for a grandiose adventure: a wizard, a prophecy, an unwitting hero. Emmet is just a model construction worker, living his city life to the tee by following every rule in the book. He is manically happy just to be doing it right: greeting his alarm…
As an alternative to biblical creationism, Intelligent Design infers a less obtrusive God to explain life on Earth. This deity doesn't hurl bolts of lightning, unless it's with the express purpose of sparking abiogenesis in the primordial soup. On EvolutionBlog, Jason Rosenhouse dismisses…
The price of human genome sequencing has fallen spectacularly since the turn of the century; what then cost $100,000,000 is now promised for only $1000. This race toward zero makes even Moore's Law look like a snail's pace, but the $1000 price tag does come with a couple asterisks. For one,…
Ethan Siegel calls Mars "the obvious first step in our journey to the stars" and "part of our dreams for reaching out into the Universe." Last year thousands of people applied to join Mars One, a proposed colonization effort slash reality show that plans to put humans on the red planet in 2023. But…
The anti-scientific M.O. of some political conservatives was in full swing during the 'polar vortex,' as frigid weather brought south from the Arctic led many commentators to scoff, "look how cold it is, can you believe anyone thinks the Earth is getting warmer?" Coby Beck adds some perspective…
Aristotle thought that there could be no lasting void in the natural order, that any emptiness would be instantaneously filled. Of course Aristotle was full of batty ideas. But this one came to be rephrased by philosophers and Vulcans alike as "nature abhors a vacuum," enduring as a powerful…
This is a story with a happy ending, or at least a happy middle, because it isn’t over yet. Right after it began I found myself floating face down in the water, drifting very slowly with the current, trying to stand but hardly able to move my legs. Trying to swim, but unable to move my arms. …
Coldness can manifest where you least expect it: on a planet rapidly warmed by the combustion of fossil fuel, or in the heart of a star 250 times as massive as our own. On Greg Laden's Blog, Greg explains that an apparent "recovery" of Arctic sea ice from its historic low in 2012 does not…
