Physics news

New soliton laser pulses deliver high energy in a trillionth of a second

Scientists have developed a new type of laser that can deliver high amounts of energy in very short bursts of time, with potential applications in eye and heart surgery or the engineering of delicate materials.

Energy-recovery linear accelerator proposed for next-generation physics research

As physicists developed plans for building an electron-ion collider (EIC)—a next-generation nuclear physics facility to be built at the U.S. Department of Energy's Brookhaven National Laboratory for nuclear physics research—they explored various options for accelerating the beams of electrons. One approach, developed by scientists at Brookhaven Lab and Stony Brook University, was to use an energy-recovery linear accelerator (ERL). The ERL would bring the electrons up to the energy needed to probe the inner structure of protons and atomic nuclei, and then decelerate the electrons and reuse most of their energy. The R&D to develop the innovative ERL may end up having a major impact in a different area of physics—high-energy particle physics, where the power needs make its energy-saving features particularly attractive.

Pairing lasers with microwaves makes mind-bogglingly accurate electronic clocks

Time and frequency standards are a key part of technologies we have come to rely on in our daily lives, from GPS navigation and cellphone networks to the electrical power grid. The importance of these systems and the constant drive to improve their performance has led to the development of atomic clocks that keep time and measure frequency with incredible accuracy.

Applying physics to understanding the mystery of consciousness

An international study involving Monash physicists has cornered a new approach to measure consciousness, potentially changing our understanding complex neurological problems.

Researchers observe protons 'playing hopscotch' in a high-pressure form of ice

An international team of researchers from University College Dublin (UCD) and University of Saskatchewan, Canada, have observed 'proton-hopping' movement in a high-pressure form of ice (Ice VII lattices).

Researchers demonstrate high-efficiency emission of dispersive wave in gas-filled hollow-core photonic crystal fibers

In the past decade, anti-resonant, hollow-core photonic crystal fibers (HC-PCFs) have become excellent platforms for studying ultrafast nonlinear optics such as ultrashort pulse compression to the single-cycle regime, efficient generation of tunable dispersive wave (DW) at deep and vacuum ultraviolet wavelengths and soliton-plasma interactions.

Astronomy and Space news

Astronomers see 'cosmic ring of fire,' 11 billion years ago

Astronomers have captured an image of a super-rare type of galaxy—described as a "cosmic ring of fire"—as it existed 11 billion years ago.

Solving the space junk problem

Space is getting crowded. Aging satellites and space debris crowd low-Earth orbit, and launching new satellites adds to the collision risk. The most effective way to solve the space junk problem, according to a new study, is not to capture debris or deorbit old satellites: it's an international agreement to charge operators "orbital-use fees" for every satellite put into orbit.

Beta Cephei-type pulsations detected in V453 Cygni

Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have detected Beta Cephei-type pulsations in an eclipsing binary system known as V453 Cygni. The finding, detailed in a paper published May 15 on arXiv.org, could be helpful in improving the understanding of the structure and evolution of stars in eclipsing binaries.

Galactic crash may have triggered solar system formation

The formation of the Sun, the Solar System and the subsequent emergence of life on Earth may be a consequence of a collision between our galaxy, the Milky Way, and a smaller galaxy called Sagittarius, discovered in the 1990s to be orbiting our galactic home.

Image: Hubble sees stellar glitter in a cosmic void

Unlike a spiral or elliptical galaxy, the galaxy KK 246 looks like glitter spilled across a black velvet sheet. KK 246, also known as ESO 461-036, is a dwarf irregular galaxy residing within the Local Void, a vast region of empty space. This lonely galaxy is the only one known for certain to reside in this enormous volume, along with 15 others that have been tentatively identified.

Could theorized Planet 9 be a primordial black hole? Researchers propose method to find out

There are eight classical planets in our solar system, from speedy Mercury to distant Neptune. There are also numerous dwarf planets, such as Pluto and Ceres. While we continue to find more dwarf planets, there are some hints that another large planet could lurk far beyond Neptune. This Planet Nine is thought to be a "super-Earth," about five times the mass of our planet, which would make it about twice as large as Earth. But despite several searches for the planet, it has not yet been found.

Video: One billion stars and counting—the sky according to Gaia's second data release

Launched in 2013, ESA's Gaia satellite has been scanning the sky to measure the positions, distances and motions of more than one billion stars in our galaxy, the Milky Way. The goal of the mission is to create the most detailed galactic map ever made, in order to investigate the Milky Way's past and future history like never before.

Technology news

A model that estimates tactile properties of surfaces by analyzing images

The ability to estimate the physical properties of objects is of key importance for robots, as it allows them to interact more effectively with their surrounding environment. In recent years, many robotics researchers have been specifically trying to develop techniques that allow robots to estimate tactile properties of objects or surfaces, which could ultimately provide them with skills that resemble the human sense of touch.

Artificial intelligence for optimized mobile communication

While many European states are currently setting up the 5th generation of mobile communication, scientists are already working on its optimization. Although 5G is far superior to its predecessors, even the latest mobile communication standard still has room for improvement: Especially in urban areas, where a direct line of sight between emitter and transceiver is difficult, the radio link does not yet function reliably. Within the recently launched EU project ARIADNE, eleven European partners are researching how an advanced system architecture "beyond 5G" can be developed by using high frequency bands and artificial intelligence.
