How Did People Migrate to the Americas? Bison DNA Helps Chart the Way [The New York Times] “Two teams of scientists have succeeded in dating the opening of the gateway to America, only to disagree over whether the Clovis people — one of the first groups from Siberia to reach the Americas — ever used the gateway to gain access to the New World.” [more inside]
Grilling with Lava [New York Times]
This July Fourth, we offer an intense, but minimalist way to grill steak. It requires 800 pounds of Wisconsin basaltic gravel heated to 2,000 degrees. New York Times food writers have advocated cooking directly on hot coals this Fourth of July, but the truly adventurous may want to consider another approach: lava-grilled steak. The Syracuse University professors Bob Wysocki and Jeff Karson, the leaders of this minimalist technique, say the key is to start with thin-cut steaks, the more marbled the better. You then find the nearest retrofitted bronze furnace. (Very likely, that is the one the professors have built for themselves in Syracuse as part of the university’s Lava Project. When not cooking dinner with it, Mr. Wysocki, an artist, and Mr. Karson, a geologist, create lava for scientific research and sculptures.)[more inside]
When Birds Squawk, Other Species Seem to Listen by Christopher Solomon [New York Times]
A professor’s hunch is that birds are saying much more in warning of danger than previously suspected, and that other animals have evolved to understand the signals.
When words fail: women, science, and women-in-science – [Trigger warning for this and all following links] by Jacquelyn Gill (@JacquelynGill):
The seminars, workshops, blogs, op-eds, research, policy papers, luncheons, and happy hour discussions are all valuable, and important, and they need to continue. But when the beer is drunk, and the pizza gone cold, and the printed articles relegated to the recycling bin, we are left with words: words written by us and about us, spoken in confidence, tossed like poisoned barbs in the comments sections, smoldering as craters in our in-boxes, pounding in our ears when we run it out at the gym.[more inside]
I’m sorry, you guys, but words are not enough. Not anymore.
Cheetahs’ Secret Weapon: A Tight Turning Radius [New York Times]
"Anyone who has watched a cheetah run down an antelope knows that these cats are impressively fast. But it turns out that speed is not the secret to their prodigious hunting skills: a novel study of how cheetahs chase prey in the wild shows that it is their agility — their skill at leaping sideways, changing directions abruptly and slowing down quickly — that gives those antelope such bad odds."
Why are owls so wise? Perhaps it's because they're utter badasses.
Ferocity is essential for a bird whose frigid, spotty range extends across northeastern China, the Russian Far East and up toward the Arctic Circle, one that breeds and nests in the dead of winter, perched atop a giant cottonwood or elm tree, out in the open, in temperatures 30 degrees below zero Fahrenheit. Dr. Slaght’s colleague Sergei Surmach videotaped a female sitting on her nest during a blizzard. “All you could see at the end was her tail jutting out,” Dr. Slaght said.The New York Times Science section gives an update on some current owl research.

An experiment done in the 1990s exposed children to various levels of lead. The lawsuit filed in 2001 by the parents of over 100 participants accuses the Kennedy Krieger Institute that the scientists knowingly used the kids as test subjects in toxic dust control study. [more inside]
Rethinking Earthrise. On the 40th anniversary of the NASA's Apollo 8 mission [caution: weird JFK animation], which answered Stewart Brand's epochal, LSD-inspired question "Why haven't we seen a photograph of the whole Earth yet?" with an unforgettable image of a seemingly fragile and isolated blue planet, Nature editor Oliver Morton -- author of a new book on photosynthesis called Eating the Sun -- disputes the notion that the Earth is fragile and isolated. "The fragility is an illusion," he writes. "The planet Earth is a remarkably robust thing, and this strength flows from its ancient and intimate connection to the cosmos beyond. To see the photo this way does not undermine its environmental relevance -- but it does recast it."
Recent neuroscience research suggests that Democrats and Republicans are not nearly as far apart as they seem (NYT). Will an awareness that we are conning ourselves to feel alienated from each other help to close the political gap? Or, are we conned by science and the media?
Savant for a Day! NYTimes journalist Lawrence Osbourne becomes a guinea pig for a University of Sydney's professor's mind-enhancing device based on the theories of autistic "Rainman" cognition with interesting results.
DNA used to ascertain race of unidentified serial killer. Florida company DNAPrint Genomics claims their test can identify the race (ie, African, Caucasian, East Asian or American Indian) of a person from their DNA. CEO Tony Frudakis says that "of over 2,200 blind samples tested, the test is yet to get one wrong."
It's about Time this guy was recognized with accolades as the premiere whistleblower in the US. Just think of all the tax money that could be saved if everyone learned what Postol already knows!

THAT'S a speeding ticket... Scientists push light up to 300 times the SPEED OF LIGHT. I just got a floaty-glowy feeling. Some interesting interesting stuff is happening in our world.
