Wave

Scientists at MIT have directly captured signs of “second sound” in a superfluid for the first time. This bizarre phenomenon occurs when heat moves like sound waves through an unusual state of matter.

Gigantic waves can seemingly come out of nowhere, threatening ships and oil rigs. Now, an AI system trained on centuries of data has been able to predict when these rogue waves will occur, revealing new insights into how they form.

With the aid of arms control technology and artificial intelligence, a team of scientists at Cardiff University's School of Mathematics has developed a method that uses underwater microphones to provide early warnings of potentially deadly tsunamis.

Much of the heat and carbon produced by humans is absorbed by the ocean. New research has shed light on the role that underwater waves play in moving that heat and carbon around our oceans, an important factor in predicting climate change.

Researchers are reporting a record-setting new example of a phenomenon known as a rogue wave, with a four-story-tall behemoth that occurred off the coast of Canada confirmed as the most extreme ever measured.

A team of researchers is proposing a radical new technique for killing cancer cells using low-intensity ultrasound waves. The work is still at an early stage but cell tests have shown sound waves can destroy cancer while leaving healthy cells intact.

URGOnight is a novel sleep training device designed to improve your ability to get to sleep, and stay asleep​, through the use of neurofeedback and brain training. The system, comprising an EEG headset and accompanying mobile app, is currently crowdfunding on Indiegogo.

​The wild waters off to the south of New Zealand have played host to record-breaking swell, with a buoy moored in the Southern Ocean picking up the largest wave ever recorded in the Southern Hemisphere.​

A new world record for the highest wave has been recorded by the World Meteorological Organization (WMO). In the freezing, turbulent waters of the North Atlantic Ocean, somewhere between Iceland and the UK, an automated buoy detected a significant wave height of 19 m (62.3 ft).

A group of scientists from the University of Miami have been tracking waves of a different breed – unseen colossal, skyscraper-tall underwater waves that are present in every one of our oceans.

A new MIT study has examined the possibility of acoustic-gravity waves – high-speed sound waves often generated by underwater earthquakes and landslides – acting as an early warning of tsunamis and rogue waves.

If you've ever tried to retrieve an object that's floating away from you, then you'll know how frustrating it can be. According to recent research, however, it's possible to move such objects in whichever direction you wish – as long as you can generate the right type of waves.
