Why? Start Quiz Pigeons 18,500 years old. In a find that’s igniting controversy in the field, archaeologists working near the southern tip of Chile have uncovered what they say are the oldest stone tools in the Americas—a set of 39 artifacts including a stone “chopper.” If verified, the finding would push back the earliest evidence for the peopling of the Americas by nearly 4000 years. You Create a TNT-sensing earthworm Pigeons. It may sound like a bird-brained idea, but scientists have trained pigeons to spot cancer in images of biopsied tissue. Individually, the avian analysts can’t quite match the accuracy of professional pathologists. But as a flock, they did as well as trained humans, detecting cancerous cells 99% of the time, according to a new study. But that doesn’t mean you’ll see them wearing white coats any time soon—in addition to missing out on some important clinical knowledge, they also seem to be lacking a certain bedside manner. Time’s Up! Make an electricity-conducting rose Click to enter Zebra tomatoes Standardized testing A leaked memo that came to light last week revealed that the U.S. National Institutes of Health (NIH) is effectively ending support for research on this animal: Which animal has been shown to spot cancer as well as human experts? Bumblebees Increase agressiveness Atlantic salmon What working tissue have scientists grown in the lab for the first time? In a GMO workaround, Swedish researchers used organic electronics to do what? Make an electricity-conducting rose. A group of Swedish researchers last week said they had hijacked the vascular transplant system of a rose to craft a flexible electronic circuit. This “flower power,” which doesn’t have to clear the same regulatory hurdles as genetic engineering, is still young. But eventually such circuitry may help farmers eavesdrop on their crops and even control when they ripen. And if that isn’t creepy enough (for the plants, that is), the advance could one day allow people to harness energy from shrubs and trees by plugging directly into their photosynthesis machinery. Spider monkeys Average Chimpanzees. Since the NIH announced it would phase out most chimpanzee research in 2013, not a single scientist has applied to use the remaining 50 research chimps kept by the agency. That was a deciding factor behind the decision to retire the chimps, says NIH head Francis Collins. “Given this complete absence of interest in a space now approaching 3 years, I think it’s fair to say the scientific community has come up with other ways to answer the kinds of questions they used to ask with chimpanzees.” An error occurred loading the Quiz.

What the URL-snatchers are after is worth more than a little bit of notoriety: A growing slice of the $10 billion academic publishing pie comes from “gold” open-access publishing, in which authors of accepted papers pay up front for their publication. Several of the 24 hijacked sites were charging would-be authors for publication and would-be subscribers for access, whereas others were advertising payday loans and cures for baldness. The takeaway for publishers? Stop being careless about website administration and security. Dogs Chimpanzees Beefalo How did you score on the quiz?

Increase fertility. Parasitic worms bore into our organs, steal our nutrients, and sup on our blood—but their effects aren’t all harmful. A new study of people living in the Amazon rainforest suggests that certain intestinal worms can increase the number of babies women give birth to. How? By tweaking the immune system much like a human fetus, one species of roundworm reduces inflammation in its host, promoting conception and implantation of the embryo in the womb, scientists say.

Learn More Atlantic salmon. A fast-growing salmon developed by AquaBounty Technologies became the first genetically modified animal to win the blessing of FDA last week. Its approval, nearly 20 years after the biotech company first approached the agency, marks the end of a long struggle for the right to sell the fish in grocery stores. But it probably doesn’t mark the end of a contentious debate over its safety. Research has shown that it doesn’t pose a threat to human health, but many stores—including Target, Trader Joe’s, and Whole Foods—have said the “Frankenfish” won’t be gracing their shelves any time soon. 5500 years old mason01/iStockphoto Promotion of payday loans Toads. In a major coup, scientists have eliminated a deadly fungus on the Spanish island of Mallorca. Chytrid fungus, which has killed off amphibians all over the world, was set to annihilate the endangered Mallorcan midwife toad. But by applying high-strength disinfectants and airlifting tadpoles to safety over 5 years, biologists eradicated the fungus from the mountain ponds where the species has been clinging to survival. Though repeating the victory may not be easy, or even possible, the findings offer rare good news in the fight against a pathogen that has been a worldwide catastrophe. Cockatoos More flexible brain genetics. Compared with most other animals, chimpanzees are incredibly intelligent: They work with tools, communicate with complex vocalizations, and are good problem-solvers. But as smart as chimps are, their brain power pales in comparison with our own. A multitude of factors help makes the human brain superior to the chimps’, but new research indicates that looser genetic control of brain development in humans allows us to learn and adapt to our environment with more flexibility than our primate cousins.

For the first time, scientists have created vocal cord tissue made with cells from actual human vocal cords. When tested in the lab, the bioengineered tissue vibrated—and even sounded—similar to the natural thing. What’s more, researchers were able to create nearly 170 artificial cords of different sizes using cells from just five sets of real cords. The development could one day help those with severely damaged vocal cords regain their lost voices. Still unknown is whether it can help the likes of Justin Bieber.
