Eight pigeons stood in little boxes for weeks, looking at mammograms, pecking at the screen to diagnose whether breast masses are malignant or benign. Using the flock’s aggregate intelligence, they reached accuracies of 99 percent in picking out the most dangerous tumors.
As Halloween approaches, you may be watching more horror flicks. The fear you feel as you watch a victim die, the screams you make when the killer jumps out on screen--these responses are surprisingly similar to those of the poor victim in the movie.
In 1939, a Russian engineer proposed a “flying submarine” -- a vehicle that can seamlessly transition from air to water and back again. Engineers have been trying to design functional aerial-aquatic vehicles for decades with little success. Now, engineers may be one step closer to the elusive flying submarine.
Soft robots can bend, walk and grip. And, unlike their rigid counterparts, some can get flattened and bounce back into shape. Now scientists report a new advance: a way to make elastic material for soft robots that changes color when it stretches.
Inspired by a naturally occurring material found in marine mussels, researchers have created a new flame retardant to replace commercial additives that are often toxic and can accumulate over time in the environment and living animals, including humans.
The first reptile to exhibit biofluorescence has been discovered in one of the rarest species on the planet – the hawksbill sea turtle. A marine biologist stumbled upon the glowing sea turtle while filming biofluorescent coral reefs on a night dive off the Solomon Islands.
For the first time, scientists have made tire-grade rubber without the processing step — vulcanization — that has been essential to inflatable tires since their invention. The resulting material heals itself and could potentially withstand the long-term pressures of driving.
Two filmmakers drove 600 miles to the vast dry lake bed of Black Rock Desert in Nevada and built a first-of-its-kind, to-scale simulated solar system. Wiley Overstreet and Alex Gorosh, with the help of a few friends, measured precise distances using GPS coordinates, traced orbits and set up a time-lapse video from atop a mountain - all within 36 hours.
A helium balloon floated nearly 100,000 feet above the Earth, taking pictures with a GoPro, before the atmosphere popped the balloon, sending the camera plummeting. The student-scientists back on the ground waited to receive a cell-phone signal to recover the instrument, but there was only silence. Two years later, a hiker in the Arizona desert came upon the camera.
Is there anything better than a bouquet of fresh flowers? Well, as it turns out, you're not the only one who likes the smell of posies --- some flowers use their aroma to attract pollinators. Find out how airborne volatile organic compounds are involved in characteristic aromas.
Recently, Forensic Magazine sat down with John Walsh, host and creator of "America's Most Wanted," about his new show on CNN called "The Hunt." Walsh said his team have already captured four dangerous fugitives--three are now deceased--and the second season is about to begin.
Cannabis has had a tumultuous history in the United States. But, in the past few years, several states have decriminalized the plant and made it legal under heavy restrictions. This legalization has a big impact on the analytical testing industry, with labs now tasked to provide methods for cannabis potency, residual solvents, heavy metals, pesticides and more.
Astronauts living in space have objects zooming around them at 22,000 miles per hour like rogue super-bullets. Although shields and fancy maneuvers could help protect space structures, scientists have to prepare for the possibility that debris could pierce a vessel. Now, researchers are reporting on a new material that heals itself within seconds and could prevent structural penetration from being catastrophic.
Earlier this month, the FDA approved the first drug manufactured via 3-D printing. Spritam, from Aprecia Pharmaceuticals, is a drug for certain epilepsy cases. The biggest difference between this drug and others more conventionally made is the 3-D printing platform produces a drug that dissolves much faster than current fast-melt technologies. Watch how it works and hear from Aprecia's Jennifer Zieverink on why Spritam is important.
