Scientists have directly demonstrated for the first time how laser beams modify the conditions of a plasma, addressing one of the challenges in the... more

A typical laser-plasma accelerator (LPA) is driven by a single, ultrarelativistic laser pulse from terawatt- or petawatt-class lasers. Recently, there has been some theoretical work on the use... more

The field of magnetic fusion research has mysteries to spare. How to confine turbulent plasma fuel in a donut-shaped vacuum chamber, making it hot and dense enough for fusion to take place, has generated questions—and answers—for decades. more

Doughnut-shaped tokamaks—facilities designed to reproduce the fusion energy that powers... more

An obstacle to generating fusion reactions inside facilities called tokamaks is that producing the current in plasma that helps create... more

Accelerated, charged particle beams do what light does for microscopes: illuminate matter. The more intense the beams, the more easily scientists can examine the object they are looking at. But... more

When sections from two separate genes merge due to various factors, such as translocation or splicing, the hybrid that is formed is called a gene fusion.... more

Migratory pelicans have long raided Israeli fish farms, which try to deter them with loudspeakers, laser beams and by firing blank rounds from rifles. more

An international group of scientists, in cooperation with a research scientist from Skoltech, has developed a model to... more

Nuclear physics usually involves high energies, as illustrated by experiments to master controlled nuclear fusion. One of the problems is how to overcome the strong electrical repulsion between atomic nuclei which requires high energies to make them fuse. But fusion... more

Image: This box of holiday cheer is actually tubes of plasma containing suspended microparticles exposed to an electrical current to form 3D crystal structures.Called Plasma Kristall-4, this ESA–Roscosmos experiment has been helping... more

Switching light beams quickly is important in many technological applications. Researchers have now developed an 'electro-opto-mechanical' switch for light beams that is considerably smaller and faster than current models. This... more

Physicists have used high-resolution computer simulations to investigate the practicality of the CHI start-up technique. The simulations show that CHI could produce the current continuously in... more

Satellites are becoming increasingly important in our lives, as they help us meet a demand for more data, exchanged at higher speeds. This is... more

White House officials said Wednesday President Donald Trump will meet with experts, advocates and industry representatives on the problem of underage vaping later this... more

New research led by the University of Bristol has found that over half of people would be willing to donate their personal data for research to... more

The sun's surface is covered by millions of enormous plasma jets known as spicules at any given moment. Now, researchers think they... more

The fate of big-eye tuna, over-fished and in decline, could be decided this week when fishing nations meet to set quotas after failing last year to agree on... more

New research has found that over half of people would be willing to donate their personal data for research to benefit the wider general public. more

Patient-reported functional outcomes vary considerably after lower (lumbar) spinal fusion surgery. But the variability mainly reflects patient characteristics, rather than differences in care provided by surgeons or hospitals,... more

With the demonstration of a sub-picosecond thin-disk laser oscillator delivering a record-high 350-W average output power, physicists set a new benchmark and pave the path towards even more powerful lasers. more

Feng Yang, Spacety CEO and founder, talked with SpaceNews about his plans for small synthetic aperture... more

Canada's projected carbon tax must be more than quadrupled over the next 10 years to meet its Paris Agreement commitment to slash CO2 pollution, economists said... more

Professional and amateur astronomers from the NASA-funded ‘Backyard Worlds: Planet 9’ project have spotted a co-moving pair of low-mass brown... more

With the demonstration of a sub-picosecond thin-disk laser oscillator delivering a record-high 350-watt average output power, physicists at ETH Zurich set a new benchmark and pave the path toward even more powerful lasers. more

Multiple myeloma is a type of blood cancer in which malignant plasma cells, a type of white blood cell, accumulate in the bone marrow. more

The terahertz region of the electromagnetic spectrum has been the least utilized owing to inadequacies of available sources. We introduce a compact, widely frequency-tunable, extremely bright source of terahertz radiation: a gas-phase molecular laser based on... more

Special light beams can be used to manipulate molecules or small biological particles. However, these optical tweezers only work with objects in empty space.... more

A new species of comma shrimp that lived during the mid-Cretaceous period, between 95 and 90 million years... more

Researchers at the Department of Energy's SLAC National Accelerator Laboratory have invented a way to observe the movements of electrons with powerful... more
