Friday coffee break

Every Friday at Nothing in Biology Makes Sense! our contributors pass around links to new scientific results, or science-y news, or videos of adorable wildlife, that they’re most likely to bring up while waiting in line for a latte.

From Devin: What Nature has to say about Canadian scientific funding protests.

If the Harper government has valid strategic reasons to undermine vital sectors of Canadian science, then it should say so — its people are ready to listen. If not, it should realize, and fast, that there is a difference between environmentalism and environmental science — and that the latter is an essential component of a national science programme, regardless of politics.

Also from Devin: Questions regarding peer-review and how cross-review can help.

How many scientific results published today in peer-reviewed journals would melt equally fast if subjected to thorough scrutiny by so many peers? How many of those faulty papers will never be challenged? How many of those will be used, as references counted but never read, to justify research grants and appointments for years to come, displacing others?

From Amy: Who would swerve to hit a turtle?

From Jonathan: “The costs of healthcare and over-testing” or “Will someone just fix this poor girl’s ankle?

Five months after twisting an ankle, my otherwise healthy daughter limped out of the radiology office carrying X-rays of her hands. “Mom,’’ she said, “my ankle still hurts.”

From Noah: Genetics confirms what linguists knew 90 years ago. (Yes, that is two links!)

GENETICS LINK: North and South America were first populated by three waves of migrants from Siberia rather than just a single migration, say researchers who have studied the whole genomes of Native Americans in South America and Canada.

LINGUISTICS LINK: The bottom line is that this three-way distinction was known linguistically since the 1920s (for example, Sapir 1921). Basically, it’s a division among the Eskimo-Aleut languages, which straddle the Bering Straits even today, the Athabaskan languages (which were discovered to be related to a small Siberian language family only within the last few years, not by Greenberg as Wade suggested), and everything else.

From Sarah: 97% of the surface of Greenland’s massive ice sheet melted! (And then mostly refroze.)

What was so unusual was the extent of the melting. It was even taking place near the highest point in Greenland, around Summit Station which is 3.2 km (2 miles) above sea level, which hardly ever melts.

Finally, an irresistibly titled link on an observation of bizarre human behavior: Man in goat suit seen living among goats in Utah mountains.

The goat man then put his mask back on, Creighton said, got back down on his hands and knees and scurried to catch up with the herd.  “We were the only ones around for miles,” Creighton said. “It was real creepy.”

Friday coffee break

Coffee flasks

Siphoned coffee.

Every Friday at Nothing in Biology Makes Sense! our contributors pass around links to new scientific results, or science-y news, or videos of adorable wildlife, that they’re most likely to bring up while waiting in line for a latte.

From Devin: A new service, Peerage of Science, which conducts peer review of scientific articles independently of any single journal, is evaluated in the pages of Trends in Ecology and Evolution; see also the response by Peerage of Science.

First, PoS aims to enhance the quality of reviewing by encouraging non-anonymous review, introducing ‘peer review of peer review’, providing the possibility for reviewers to publish their review as a ‘Peerage Essay’ (PE) and to build a ‘referee factor’. Previous attempts at non-anonymous review have discovered, however, that most reviewers prefer anonymity. Peer review of peer review and the implementation of a referee factor are certainly good ideas, but reviewers who want to remain anonymous would waste their time writing a PE. Additionally, it will not always be possible to have an original insight and bring new perspectives to every evaluated paper, and the PE could become outdated after manuscript revision. A solution could be to let the comments to authors be assessed by the other reviewers and make the writing of a PE optional. [In-text citations removed.]

(Jeremy also notes that PoS is either an unfortunate, or a brilliant, abbreviation for a peer review system.)

From Sarah: For the week of Valentine’s Day, Paleontology writer Bryan Switek considers what we know about the mating habits of dinosaurs.

Rather than simply leaning straight against the top of a female like an elephant or rhinoceros does, a male sauropod would probably have to rear up at a relatively oblique angle, and the female would have to assist by moving her tail (which is also a way in which female dinosaurs could have exerted mate choice and confounded any hot-under-the-collar males they would rather not mate with).

From Jon: New research finds that interval training—exercise in a series of brief bursts—can improve fitness faster than more time spent in sustained exertion.

Several years ago, the McMasters scientists did test a punishing workout, known as high-intensity interval training, or HIIT, that involved 30 seconds of all-out effort at 100 percent of a person’s maximum heart rate. After six weeks, these lacerating HIIT sessions produced similar physiological changes in the leg muscles of young men as multiple, hour-long sessions per week of steady cycling, even though the HIIT workouts involved about 90 percent less exercise time.

From Jeremy: Documents leaked from a conservative think-tank with ties to companies like GM and Microsoft reveal plans to excise climate change from basic science education.

One thing I want to point out right away which is very illuminating, if highly disturbing, about what Heartland allegedly wants to do: they are considering developing a curriculum for teachers to use in the classroom to sow confusion about climate change. I know, it sounds like I’m making that up, but I’m not. In this document they say:

[Dr. Wojick‘s] effort will focus on providing curriculum that shows that the topic of climate change is controversial and uncertain – two key points that are effective at dissuading teachers from teaching science.
