Sixth grader's internet-famous science project misleadingly promoted as "new"

This is scientist Zack Jud, posing with a lionfish he caught in a estuary river in 2010 — four years before 6th grader Lauren Arrington, who is now being credited with the discovery.

When a black woman becomes a white man online

Blogger Mikki Kendall is black, female, and receives a daily deluge of violent, threatening invective. When she temporarily "became" a white man, all that changed.

How does a brain-eating amoeba eat brains?

Is "brain eating" a metaphor or exaggeration of how the amoeba works? No, actually. It really does literally eat brains. Here's how.

From the Wellcome Image Collection, this is how you pumped your breasts 150 years ago. Via the fantastic Twitter feed of Dr. Lindsey Fitzharris.

If correlation doesn't imply causation, what does?

Open science advocate Michael Nielson writes about how scientists can infer causation in situations where it's not possible to do a randomized controlled trial.

The Apollo program was not always popular

It holds a singular place in the American imagination today, but there was a lot of opposition to the Apollo program as it was happening.

How sandstone arches form


It's not caused by erosion. Instead, the rock, itself, forms the arch and the erosion just washes away everything else around it.

Giving up on saving the world

Grist has an interview with activist and writer Paul Kingsnorth, a former environmentalist who has decided that the right way to deal with the end of the world is to just accept its inevitability.

Metalhead visits neurologist

In a rare complication of being a metalhead, a 50-year-old Motorhead fan developed a brain bleed after combining enthusiastic headbanging with a benign cyst.

The limits of animal life on Tatooine

Maggie Koerth-Baker on why the megafauna of George Lucas' parched desert world makes no sense. It's not the dry heat that's the problem; it's the food supply.Read the rest

Baby blood samples stored for research without parent permission

If you had a baby in Indiana after 1991, chances are your child's blood and DNA samples are being stored by the state. Originally meant for research, no samples have been used because consent of parents was never obtained.

After smallpox find, big questions about safety in federal research labs

Popular Science has a nice follow up to the news about the discovery of decades-old smallpox samples — including the fact that scientists found 327 vials of other forgotten disease samples in the same place.

Behind the science of stress, the hand of Big Tobacco

Stress does affect the body in numerous ways. But how we think about what stress is, what it does, and its connection to pop psychology, have all been shaped by cigarette companies.

When food has an offensive name


The "kaffir" in "Kaffir lime" is actually a racial slur. At National Geographic, Maryn McKenna struggles with how to deal with foods that have offensive names.

I ran across a campaign, launched initially on Twitter, to rename the kaffir lime, a bumpy-skinned fruit from Southeast Asia with deeply perfumed leaves. “Kaffir” is a slur: In apartheid South Africa, whites hurled it against blacks. Writer Mark Mathabane, who was born in a Johannesburg shantytown during apartheid, used it to title his memoir, Kaffir Boy. In modern South Africa, uttering the word is scandalous hate speech, and defamation suits have been brought and won over it. Just this week, South Africa’s Supreme Court of Appeal upheld a man’s sentence (of a fine and a year in jail) for using it, saying in a unanimous opinion: “The word is racially abusive and offensive… its use is not only prohibited but is actionable as well.”

Modern spiders related to 500-million-year-old nightmare beasts

Anomalocarids are the ancient ancestors of spiders. They look like menu items from H.P. Lovecraft's seafood restaurant.

The horrible seating configuration Airbus wants to patent


Here's the patent application. The "good" news: It's just conceptual. Regulators wouldn't let Ryanair sell standing room tickets, so maybe this would be banned as well?

Myers-Briggs personality test isn't actually based on science

It's fun to take, but the results of a Myers-Briggs personality test are basically meaningless — inconsistent and based on unsupported, philosophical ideas about how the brain operates.

Your blood type can influence whether you get sick

Your risk of contracting norovirus — that scourge of cruise vacations — depends both on the strain of the virus and what your blood type is.

What happens in babies' brains between babbling and speech


Most babies babble by 7 months of age. Most don't start talking real words until they're a year old. What's going on in their heads in the meantime?

This is kind of your standard hook-a-baby-up-to-a-brain-scanner-and-see-what-lights-up research. But I think it is particularly interesting in the way that it emphasizes the very hard work that goes into getting the muscle movements of face, tongue, and vocal cords coordinated in just the right way in order to say what it is that you want to say. We often talk about the "can't talk yet" stage of babyhood as though the baby isn't processing speech yet and doesn't understand words. But that's not really true. At a certain point, they get the words, but can't necessarily get their bodies to repeat the words. (And, in fact, this is exactly the sort of situation that infant sign language is meant to address.)

The study has social implications, suggesting that the slow and exaggerated parentese speech – “Hiiiii! How are youuuuu?” – may actually prompt infants to try to synthesize utterances themselves and imitate what they heard, uttering something like “Ahhh bah bah baaah.”

“Parentese is very exaggerated, and when infants hear it, their brains may find it easier to model the motor movements necessary to speak,” Kuhl said.

Bonus: More photos and video of babies attached (kind of adorably, from my perspective) to brain scan equipment.

The relationship between cheese flavor and the land cows graze on

To make your cheese, cows eat and process food that we are incapable of eating and processing. This video explains how the chemistry of the land (and grass) change the flavor of the cheese we eat.

What it's like to have chronic vaginal pain

Lara Parker at Buzzfeed writes about her experience with vaginismus and vulvodynia — chronic pain conditions with no known cause, no known treatment, and a big impact on love and relationships.

The downside to being preserved for posterity

We have found only 17 mammoth specimens that are more than half complete with their soft parts preserved. All but one died a horrible death.

Scientific journal retracts 60 papers linked to sock-puppet peer review

This is just a crazy level of fraud. A Taiwanese computer scientist has been caught creating more than 100 fake email accounts that allowed him to "peer" review his own research.
