Impact-absorbing DCLR8 is like a rear crumple zone for helmets

Although helmets are required for many sports, Canadian materials engineering technologist Albert Beyer believes that they don’t provide enough protection to the back of the head. His solution to that problem is a “crumple zone for helmets” known as th… Continue reading Impact-absorbing DCLR8 is like a rear crumple zone for helmets

Smart hockey helmet assesses players’ knocks to the noggin

While all team sports can be rough, hockey poses a particularly high risk of brain injuries. A new high-tech helmet is designed to warn of such injuries, by detecting and reporting on knocks to its wearer’s head.Continue ReadingCategory: Health & W… Continue reading Smart hockey helmet assesses players’ knocks to the noggin

“Ultra-shock-absorbing” foam packs a plethora of carbon nanotubes

Carbon nanotubes have found use in everything from heart-rate-monitoring shirts to smart bandages to more efficient solar cells. Now, scientists at the University of Wisconsin-Madison have used them in a helmet lining foam that offers better impact pro… Continue reading “Ultra-shock-absorbing” foam packs a plethora of carbon nanotubes

Huge potentially hazardous asteroid discovered hiding in Sun’s glare

Astronomers have discovered a trio of new near-Earth asteroids (NEAs), including the closest known to the Sun. Another is one of the largest known asteroids considered potentially hazardous to Earth, measuring almost a mile wide with an orbit that may … Continue reading Huge potentially hazardous asteroid discovered hiding in Sun’s glare

Wild simulations of cosmic collisions show the Moon forming in just hours

It’s believed that the Moon formed billions of years ago, from debris from a cosmic collision with Earth. New high-resolution simulations not only illustrate the idea in stunning detail, but reveal that the Moon’s birth might have taken mere hours.Cont… Continue reading Wild simulations of cosmic collisions show the Moon forming in just hours

Newly discovered crater suggests multiple asteroids killed dinosaurs

The Earth still bears the scar of the gigantic asteroid impact that wiped out the dinosaurs, along with three quarters of all life – but a new study suggests that killer rock wasn’t alone. Scientists have discovered a new crater in the seabed of the No… Continue reading Newly discovered crater suggests multiple asteroids killed dinosaurs

The tense journey from “riskiest asteroid in a decade” to no threat

Astronomers had a tense few days in January, as a newly discovered space rock became the riskiest asteroid in a decade – and then hid behind the Moon for a week. Thankfully, further observations have now found that it poses no risk to Earth when it swi… Continue reading The tense journey from “riskiest asteroid in a decade” to no threat
