New System Improves Minimally Invasive Surgery?

New System Improves Minimally Invasive Surgery?

Johns Hopkins researchers have devised a computerized process that could make minimally invasive surgery more accurate and streamlined using equipment already common in the operating room.   In a report published recently in the journal Physics in Medicine and Biology, the researchers say initial testing of the algorithm shows that their image-based guidance system is [...]

Smart Tag Shows When Food Has Gone Bad

Smart Tag Shows When Food Has Gone Bad

A color-coded smart tag could tell consumers whether a carton of milk has turned sour or a can of green beans has spoiled without opening the containers, according to researchers. The tag, which would appear on the packaging, also could be used to determine if medications and other perishable products were still active or fresh, [...]

Physics of Curly Hair: First Detailed Model

Physics of Curly Hair: First Detailed Model

The heroes and villains in animated films tend to be on opposite ends of the moral spectrum. But they’re often similar in their hair, which is usually extremely rigid or — if it moves at all — is straight and swings to and fro. It’s rare to see an animated character with bouncy, curly hair, [...]

Fever-Reducing Meds May Help Spread the Flu

Fever-Reducing Meds May Help Spread the Flu

Contrary to popular belief, fever-reducing medication may inadvertently cause more harm than good.   New research from McMaster University has discovered that the widespread use of medications that contain fever-reducing drugs may lead to tens of thousands more influenza cases, and more than a thousand deaths attributable to influenza, each year across North America. These [...]

Gimball: A Crash-Happy Flying Robot

Gimball: A Crash-Happy Flying Robot

Gimball bumps into and ricochets off of obstacles, rather than avoiding them. This 34 centimeter in diameter spherical flying robot buzzes around the most unpredictable, chaotic environments, without the need for fragile detection sensors. This resiliency to injury, inspired by insects, is what sets it apart from other flying robots. Gimball is protected by a [...]
