Jeff sez, "Researchers often use Photoshop to clean up the images they produce in the laboratory. If the experiment didn't go quite right, a bit of tampering can make a gel look like things did work. Editors at Science, Nature, and other journals are turning into detectives, using new tools to hunt for fraudulent images."
And the level of tampering they find is alarming. "The magnitude of the fraud is phenomenal," says Hany Farid, a computer-science professor at Dartmouth College who has been working with journal editors to help them detect image manipulation. Doctored images are troubling because they can mislead scientists and even derail a search for the causes and cures of disease.
Ten to 20 of the articles accepted by The Journal of Clinical Investigation each year show some evidence of tampering, and about five to 10 of those papers warrant a thorough investigation, says Ms. Neill. (The journal publishes about 300 to 350 articles per year.)
Ant Lab's Adrian Smith (previously) writes, "No one had ever filmed how ants inject venom when they sting something. I study ants and I make videos, so I went to work on getting that footage. It involved filming something smaller than a human hair moving faster than the blink of an eye. But, I got […]

Above is a three-millimeter long maggot launching itself into the air for a distance of up to 36 times its body length. Researchers from Duke University and their colleagues studied how these larvae of gall midges leap between plants with the greatest of ease, even rivaling some jumping insects with legs. Their research could have […]
Want to keep the dentist away? A little tooth care at morning and night isn’t bad, but it won’t keep the stains from smoking or fried foods at bay for long. If you enjoy your food and want to avoid the consequences, an upgrade from that old analog toothbrush can make a huge difference. Among […]
If your office works at all, it uses Microsoft Office. Those icons for Word, PowerPoint, and Outlook are as familiar around some workplaces as the coffee machine. So familiar, in fact, that they get taken for granted – and rarely used to their full potential. Whether you need a crash course in the essential tools […]
It’s a great time to be a maker. 3D printers are on store shelves for anyone to buy, and coder kits like Arduino and Raspberry Pi are letting kids as young as 9 or 10 dive into the Internet of Things. Here are a few examples of our favorite tech toys, all priced low enough […]
