Researcher creates a controlled rogue wave in realistic oceanic conditions
Potentially extremely dangerous realistic rogue waves can now be controlled and generated at will in laboratory environments, in similar conditions as they appear in the ocean. This will help to predict oceanic extreme events and to design safer ships and offshore rigs. Newly designed vessels and rig model prototypes can be tested to encounter in a small scale, before they are built, realistic extreme ocean waves. (2016-10-03)

Safer shipping by predicting sand wave behavior
Dutch researcher Joris van den Berg has developed a mathematical model to predict the movement of sand waves. Sand waves are formed by an interaction between the tidal current and sand. They are larger than sand ripples on the beach but smaller than sandbanks. Sand waves largely determine the shape of the sea floor in the southern part of the North Sea. A good predictive computer model would be a valuable tool for shipping and designers of offshore infrastructures. (2007-07-12)

Taming plasmas: Improving fusion using microwaves
We all know microwaves are good for cooking popcorn, but scientists have recently shown they can also prevent dangerous waves in plasmas and help produce clean, nearly limitless energy with fusion. Fusion takes place when fast moving atomic particles slam into each other and stick together. The particles need to be so hot that atoms break down, leaving a gas of charged particles called a plasma. (2018-11-05)

The storm that never was: Why the weatherman is often wrong
Have you ever woken up to a sunny forecast only to get soaked on your way to the office? On days like that it's easy to blame the weatherman. But BYU engineering professor Julie Crockett doesn't get mad at meteorologists. She understands something that very few people know: it's not the weatherman's fault he's wrong so often. (2013-01-24)

Magnetoacoustic waves: Towards a new paradigm of on-chip communication
Researchers have observed directly and for the first time magnetoacoustic waves (sound-driven spin waves), which are considered as potential information carriers for novel computation schemes. These waves have been generated and observed on hybrid magnetic/piezoelectric devices. The experiments were designed by a collaboration between the University of Barcelona (UB), the Institute of Materials Science of Barcelona (ICMAB-CSIC) and the ALBA Synchrotron. The results show that magnetoacoustic waves can travel over long distances -up to centimeters- and have larger amplitudes than expected. (2020-04-06)

Rocket to measure auroral waves
University of Alaska Fairbanks Poker Flat Research Range will open its 2003 launch season today with a single-rocket mission designed to measure high-frequency wave signals in connection with the aurora.

URI oceanography student uses crashing waves on shorelines to study Earth's interior
Scientists have long used the speed of seismic waves traveling through the Earth as a means of learning about the geologic structure beneath the Earth's surface, but the seismic waves they use have typically been generated by earthquakes or man-made explosions. A URI graduate student is using the tiny seismic waves created by ocean waves crashing on shorelines around the world to learn how an underwater plateau was formed 122 million years ago.

Towards mastering terahertz waves?
Terahertz waves allow for the detection of materials that are undetectable at other frequencies. However, the use of these waves is severely limited by the absence of suitable devices and materials allowing to control them. Researchers at UNIGE working with the ETHZ have developed a technique based on the use of graphene, which allows for the potentially very quick control of both the intensity and the polarization of terahertz light. (2017-03-07)

Microscopic deformation of a neutron star inferred from a distance of 4500 light-years
Gravitational waves, which are ripples in spacetime, have recently provided a new window to the universe. But continuous gravitational waves, for example from a slightly deformed and spinning neutron star, a star which is incredibly dense, have so far not been detected. A recent research work by Prof. Sudip Bhattacharyya has inferred continuous gravitational waves from a neutron star and has estimated the stellar microscopic deformation from a distance of about 4500 light-years.

RUDN mathematicians confirmed the possibility of data transfer via gravitational waves
RUDN mathematicians analyzed the properties of gravitational waves in a generalized affine- metrical space (an algebraic construction operating the notions of a vector and a point) similarly to the properties of electromagnetic waves in Minkowski space-time. It turned out that there is the possibility of transmitting information with the help of nonmetricity waves and transferring it spatially without distortions. The discovery can help the scientists master new means of data transfer in space, e.g. between space stations. (2018-10-10)
