The US Is Finally Trying to Unlock the Power of Wave Energy

Their energy potential is astonishing—researchers estimate that waves off the coasts of the United States could generate as much as 2.64 trillion kilowatt-hours annually, equivalent to 64 percent of the country’s total electricity generation in 2019.But capturing the immense power radiating across our oceans’ surfaces is no easy feat—wave energy technology is challenging to engineer, startup costs are high, and testing in open ocean waters is a regulatory nightmare.

The Secret Ingredient That Powers Supernovas

Whenever theorists tried to model these intricate particle motions and interactions in computer simulations, the supernova’s shock wave would stall and fall back on itself.Only in the last few years, with the growth of supercomputers, have theorists had enough computing power to model massive stars with the complexity needed to achieve explosions.

Looking for Gravitons? Check for the ‘Buzz’

Dyson’s 2013 calculation convinced many people that gravitational wave detectors were, at best, impractical probes for learning about quantum gravity.“There’s a kind of default consensus that it’s a waste of time to think about quantum effects and gravitational radiation,” said Frank Wilczek, a Nobel Prize-winning physicist at MIT who was a coauthor with Parikh on the new paper.

What Singapore Can Tell the World About Personal Liberty

On the back of Wired, CNN, and Time praising Singapore’s response in early March, the Singapore government made moves which political commentators have read as suggesting the possibility of snap elections, including announcing the new electoral boundaries on March 13, as if to leverage goodwill in the midst of crisis to solidify political power.

Scientists Are Getting Better at Predicting Killer Heat Waves

Scientists Are Getting Better at Predicting Killer Heat Waves

For now, they’re looking back in time, working to see how accurately their model captures heat waves globally and in the various seasons, and whether it accurately represents the high and low pressure systems created by the MJO.In North America, says Julie Caron, an associate scientist at the center’s Climate and Global Dynamics Lab, the oscillation causes high-pressure systems that block the movement of cooler air from the Arctic or the Pacific Ocean.

The Secret to Soap Bubbles' Iridescent Rainbows

When it comes to reflected light, you get a half wavelength phase shift if it reflects off a material with a higher index of refraction. As the film thickness changes, different wavelengths of light achieve constructive interference.

Get Ready For Gravitational Waves All Day, Every Day

For example, multiple signals of the same gravitational wave allow you to pinpoint more precisely where it originated, much like GPS uses multiple satellites to locate your position, says Jo van den Brand of VU Amsterdam, who leads an Italy-based gravitational wave observatory known as Virgo.

Why a Grape Turns Into a Fireball in a Microwave

A common misconception is that the microwave acts on the grape from the outside in, like frozen meat defrosting, says physicist Pablo Bianucci of Concordia University, who worked on grape simulations included in a paper that appears today in the Proceedings of the National Academy of Sciences .

Melting glaciers increasing risk of landslide-triggered tsunamis, study reveals

Melting glaciers could be triggering a ripple effect of natural disasters that culminates in massive tsunamis, according to new research. This problem is likely to be exacerbated along the icy coastlines of Greenland, Patagonia and Norway, where huge chunks of rock smashing into the water can create towering waves.
