Classical nova explosions involve jets of oppositely directed hot gas, plasma
Scientists at the University of Oxford have discovered that classical nova explosions are accompanied by the ejection of jets of oppositely directed hot gas and plasma, and that this persists for years following the nova eruption. Previously, such je.....»»
New research employs shutter speed analogies to validate 55-year-old theory about chemical reaction rates
Chemical reactions are commonly depicted as transitions from reactants to products. However, such reactions involve many molecules, and the individual molecules themselves undergo frequently-occurring structural changes as they transform from the rea.....»»
Researchers elucidate ultrafast laser-induced solid-to-overdense-plasma transitions
The interaction of solids with high-intensity ultra-short laser pulses has enabled major technological breakthroughs over the past half-century. On the one hand, laser ablation of solids offers micromachining and miniaturization of elements in medica.....»»
How scientific conference attendees can reduce their carbon footprint
Climate researchers often emphasize the fact that reducing carbon emissions is in everyone's best interest, and should involve all of us. But how good are they at minimizing their own carbon footprint?.....»»
Using AI to speed up and improve the most computationally-intensive aspects of plasma physics in fusion

The quantum theory of gravitation, effective field theories and strings: Past and present
Gravity is one of four fundamental interactions. The most precise description of this force is still provided by Einstein's General Theory of Relativity, published in 1915, an entirely classical theory. This description sets gravity apart from the ot.....»»
Fusion record set for tungsten tokamak WEST
Researchers at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) measured a new record for a fusion device internally clad in tungsten, the element that could be the best fit for the commercial-scale machines required t.....»»
Solar orbiter takes a mind-boggling video of the sun
You've seen the sun, but you've never seen the sun like this. This single frame from a video captured by ESA's Solar Orbiter mission shows the sun looking very fluffy! You can see feathery, hair-like structures made of plasma following magnetic field.....»»

New Nevada experiments aim to improve monitoring of nuclear explosions
On an October morning in 2023, a chemical explosion detonated in a tunnel under the Nevada desert was the launch of the next set of experiments by the National Nuclear Security Administration, with the goal to improve detection of low-yield nuclear e.....»»
Researchers say nature recovery must be integrated across all sectors to bend the curve of biodiversity loss
The alarming rates of biodiversity loss worldwide have made clear that the classical way of governing biodiversity recovery based on protected areas and programs for the protection of endangered species is not enough. To tackle this, almost 200 count.....»»
Pulsed plasma rocket (PPR): Shielded, fast transits for humans to Mars
The future of a space-faring civilization will depend on the ability to move both cargo and humans efficiently and rapidly. Due to the extremely large distances that are involved in space travel, the spacecraft must reach high velocities for reasonab.....»»
