Fidget spinner as medical diagnostic centrifuge. Some clever Koreans have figured out how to combine a fidget spinner with a microfluidic chip to get a centrifuge good enough for fast medical diagnoses that requires only hand power.

Blacktip sharks swim into shallow waters to escape an even larger predator, the great hammerhead shark. This was thought to be the case but now drones unobtrusively observing the sharks from the air have confirmed it.

"Studying mice infected with the common parasite Toxoplasma, the team discovered that sperm of infected fathers carried an altered 'epigenetic' signature which impacted the brains of resulting offspring. Molecules in the sperm called 'small RNA' appeared to influence the offspring's brain development and behaviour."

"Toxoplasma is one of the world's most common parasites, estimated to be carried by between 25 and 80 per cent of the global population." They've switched from talking about mice to people here.

"Toxoplasma infections have been shown to cause long-term epigenetic changes in a range of cells around our body. These are changes that do not alter the genetic sequence of DNA, but influence gene expression -- that is, which genes are switched on or off."

"Professor Hannan said this was the first time it had been shown that an infection in a male can result in epigenetic changes being transmitted to subsequent generations."

In case you're wondering what difference in "behavior" they're talking about, they found the toxoplasma mice behaved differently in a series of tests: an open field test (time mice spend in the center of an open field), a forced swim test, a "y-maze" test, a novel object recognition test, a sociability test, and a social recognition test.

Offspring may inherit legacy of their father's Toxoplasma infection

Introverts like mountains while extroverts like the flatlands, according to this research that graphs out flatness and extroversion by state and shows a relationship. Also they say extroverts like beaches while introverts like mountains.

I'm half-n-half -- neither introvert nor extrovert. (Apparently there's a word for this: "ambivert".) I land in the middle on the "introvert-extrovert" scale on Big 5 and Myers-Briggs personality tests, and it seem to fit as I can be by myself for hours and I don't mind and I can be with other people for hours and that's fine, too.

Having said that, the flatlands vs mountains theory is new to me and makes no sense. It seems like, some people, like my mom, like the "big sky" feeling that you get in a place that's very flat. Others like the scenic feeling from mountains. When you get very high up the scenery becomes quite dramatic.

My mom grew up in west Texas and I've been there many times to visit my grandparents and it is the flattest place I've ever been. The graph shows North Dakota as the flattest state, and I guess the problem here is they're using whole states and some like Texas are pretty big. Texas has some hills on it's eastern side where it borders Louisiana. But on the western side, well, I've been to both North Dakota and west Texas and I can tell you west Texas is flatter.

I live in Denver and maybe Denver is the perfect place for the half-n-half ambiverts who are neither introvert nor extrovert, but something in the middle. Look east, and you're on the flatlands. Look west and you're in the mountains.

Extroverts Prefer Plains, Introverts Like Mountains

Favorite science news stories of the decade from the journal Science. Of the decade! I forgot we're at the end of a decade. "Superaccurate clocks confirm your hair is aging faster than your toenails" (things closer to the ground experience time more slowly due to Einstein's relativity), "Old termites blow themselves up to protect the nest", "Microbes survive, and maybe thrive, high in the atmosphere", "How to survive a nuclear explosion", "Even in the wild, mice run on wheels", "Want to influence the world? Map reveals the best languages to speak", "How long would it take you to fall through Earth?", "'Undead' genes come alive days after life ends", "Why do shoelaces untie themselves?", "This ocean path will take you on the longest straight-line journey on Earth."
