Technology That Helps Cars And Pedestrians See Each Other

Honda is using existing vehicle-to-vehicle systems to create a network in which data broadcast and received by both cars and pedestrians will help prevent accidents.

What's the Latest Development?

Using existing technology built to allow its cars to recognize each other, Honda is extending its communications network to include pedestrians. The Vehicle-to-Pedestrian (V2P) automatic safety system takes advantage of hardware already included in smartphones, such as GPS and accelerometers, to make people on the street "visible" to its cars. It also lets the car know whether the person is paying too much attention to their phone -- texting or listening to music, for example -- and not enough attention to the road. If the person is about to step in front of the car, an audio and visual warning is sent to both.

What's the Big Idea?

Given the increase in incidents of phone-obsessed people walking into traffic, and the growing interest in vehicle-to-vehicle communications, Honda's forward-thinking approach could help save lives in more ways than one. For example, because the car receives smartphone signals from multiple directions, it can "see" when a person is moving behind it, or is hidden between other vehicles. The automaker is developing similar technology that will enable communication between cars and motorcycles and send warnings to both in case of a possible collision.

Surprising Science

While the demise of the dinosaurs gets more attention as far as mass extinctions go, an even more disastrous event called "the Great Dying” or the “End-Permian Extinction” happened on Earth prior to that. Now scientists discovered how this cataclysm, which took place about 250 million years ago, managed to kill off more than 90 percent of all life on the planet.

Why we're so self-critical of ourselves after meeting someone new

A new study discovers the “liking gap” — the difference between how we view others we’re meeting for the first time, and the way we think they’re seeing us.

Surprising Science

We tend to be defensive socially. When we meet new people, we’re often concerned with how we’re coming off. Our anxiety causes us to be so concerned with the impression we’re creating that we fail to notice that the same is true of the other person as well. A new study led by Erica J. Boothby, published on September 5 in Psychological Science, reveals how people tend to like us more in first encounters than we’d ever suspect.

NASA launches ICESat-2 into orbit to track ice changes in Antarctica and Greenland

Using advanced laser technology, scientists at NASA will track global changes in ice with greater accuracy.

Firing three pairs of laser beams 10,000 times per second, the ICESat-2 satellite will measure how long it takes for faint reflections to bounce back from ground and sea ice, allowing scientists to measure the thickness, elevation and extent of global ice

Leaving from Vandenberg Air Force base in California this coming Saturday, at 8:46 a.m. ET, the Ice, Cloud, and Land Elevation Satellite-2 — or, the "ICESat-2" — is perched atop a United Launch Alliance Delta II rocket, and when it assumes its orbit, it will study ice layers at Earth's poles, using its only payload, the Advance Topographic Laser Altimeter System (ATLAS).
