Kornmesser; Sukho Song There’s no such thing as a ‘pure’ European—or anyone elseNew studies show that there is no such thing as “pure” European—or anyone else. Almost all of us are the children of repeated ancient migrations, according to researchers who study human origins. Using revolutionary new methods to analyze DNA and the isotopes found in bones and teeth, scientists are exposing the tangled roots of peoples around the world. Few of us are actually the direct descendants of the ancient skeletons found in our backyards or historic homelands. And only a handful of groups today, such as Australian Aborigines, have deep bloodlines untainted by mixing with immigrants.Superstar surgeon fired, again, this time in Russia Click to view the privacy policy.

The Karolinska Institute in Stockholm fired him in March 2016 for multiple ethical violations, including a breach of “fundamental values” and “scientific negligence.” But Russia had long showered Macchiarini with funding and opportunities to perform his experimental surgeries to implant artificial tracheas, and it allowed him to stay. Now, a year later, his Russian refuge has ended as well.Closest alien world to our solar system could be ripe for life, models suggestCould alien life reside close to our stellar neighborhood? Astronomers are taking that question a bit more seriously as new models increasingly suggest that the closest Earth-like planet to our solar system could be habitable. One research team predicted that it would be possible for the exoplanet Proxima b—orbiting our nearest neighbor star—to harbor liquid water on its surface. Now, another team has taken a climate model designed for Earth and pasted it onto Proxima b and found an even wider range of circumstances in which Proxima b could have liquid water than the earlier study.U.S. flower sellers rush to destroy illegal GE petuniasThe U.S. Department of Agriculture announced this week that U.S. flower distributors have begun to destroy countless petunia plants after federal scientists confirmed that they were genetically engineered (GE) to produce vivid orange, red, and purple blooms. The agency says the flowers pose no risk to the environment or to human health, but GE organisms need special permits to be sold in the United States. Testing continues, but the agency says it has already confirmed nine unwelcome varieties, including ones called African Sunset, Trilogy Mango, and Sweetunia Orange Flash.Gecko-inspired gripper could help robots climb wallsIf you want a robot to pick up a coffee cup, a cherry tomato, or a bag of packaged food, you’ll have to deal with a lot of programming and quite possibly some cleanup in aisle 3. A child can handle all kinds of shapes and materials, and apply the right combination of force and delicacy when lifting them, but getting machines to reproduce these seemingly simple skills hasn’t been easy. Now, a team of researchers has developed a new way to pick up objects that solves many of these problems. Modeled on geckos’ toes, it could also help robots climb irregularly shaped walls.last_img read more

Imported wolves settle in as Lake Superior island teems with moose

first_imgA male wolf from Michipicoten, Canada, heads into its new home on Isle Royale in Michigan last month. Click to view the privacy policy. Required fields are indicated by an asterisk (*) Thirteen new radio-collared wolves are now scouting Isle Royale in Michigan and feasting on moose, whose numbers this winter reached 2060—the second highest estimate since ecologists began to study predators and prey on the island in 1958. The new wolves, imported to help restore the U.S. national park from overbrowsing by moose, are largely avoiding the territory of the remaining two wolves of the original population.Twenty female moose are also sporting radio collars, allowing biologists to watch both wolf and moose movements online. After 8 years essentially unfettered by predation because wolf numbers were so low, the moose population has been booming at 19% a year, according to data released today by Michigan Technological University (MTU) in Houghton.The new wolves are expected to check moose numbers and help restore balsam fir and other plants, according to National Park Service (NPS) planners. And the flood of GPS data is revealing “stuff we’ve never seen before,” says MTU wildlife ecologist Rolf Peterson, such as where moose congregate to feed on new spring growth. Peterson and his colleagues plan to chemically analyze the specific balsam fir trees moose eat to determine whether they choose twigs with compounds that may have anti-inflammatory properties.

These new data “will totally redirect our attention,” Peterson says.Moose in the Great Lakes region are at the southernmost edge of their range, and they are declining as the climate changes—except on Isle Royale, notes Adrian Wydeven, a wildlife biologist retired from the Wisconsin Department of Natural Resources in Cable. The new data may help scientists understand what’s behind that difference, he says. He sees the project “as more of a moose conservation effort rather than wolf conservation.”The NPS wolf relocation had a rough start, including a partial U.S. government shutdown in January, bad weather, and depleted funding. Two wolves died, one before transport, one after several weeks on the island; one imported female traveled back home when an ice bridge to the mainland formed in January.Eight wolves hail from Michipicoten Island Provincial Park in Canada across Lake Superior. (The others are from Minnesota and mainland Ontario in Canada.) Wolves on the smaller Ontario island had eliminated their chief prey, caribou, and had been subsisting mainly on beaver. These wolves appeared underfed, but they were relocated as a pack, boosting their chances of thriving on Isle Royale, Peterson says.Meanwhile, the island-born, highly inbred pair of the original population “is not giving up on each other,” says Peterson, who observed them from a spotter plane in February. As in previous mating seasons, the now 8-year-old female rebuffed the interest of the 10-year-old male, her father and half-sibling. They kept busy scent marking their territory in response to the relocated wolves as well as to tracks of other mainland wolves that apparently found their way across the ice bridge and back.The pair’s pedigree demonstrates the challenge of maintaining genetic diversity on Guam-size Isle Royale. “Inbreeding is basically inevitable due to the island’s small size,” says University of California, San Francisco, geneticist Jacqueline Robinson, who analyzed the genomes of 11 Isle Royale wolves from blood samples collected since 1988. To further diversify the population, NPS plans to import more wolves from Michigan this fall.last_img read more
