Physicists overcome two key operating hurdles in fusion reactions
A team of physicists from several institutions across the U.S. working with a colleague from China, at the DIII-D National Fusion Facility, in San Diego, California, has devised a way to overcome two key hurdles standing in the way of using fusion as.....»»
Why Germany ditched nuclear before coal—and why it won’t go back
The past year has seen record renewable power production nationwide. Enlarge / Jürgen Trittin, member of the German Bundestag and former environment minister, stands next to an activist during an action of the environmental orga.....»»
Russia stands alone in vetoing UN resolution on nuclear weapons in space

New "cold war" grows ever warmer as the prospect of a nuclear arms race hots up
Champagne corks popped on December 3, 1989 as Soviet leader Mikhail Gorbachev and US president George H.W. Bush met on the cruise ship, Maxim Gorky, off the coast of Malta to declare the end of the cold war......»»
New dataset sheds light on relationship of far-red sun-induced chlorophyll fluorescence to canopy-level photosynthesis
In recent years, the scientific community has increasingly turned its attention to sustainable agriculture, aiming to maximize crop yield while minimizing environmental impact. A crucial aspect of this research involves understanding the fundamental.....»»
A NASA rover has reached a promising place to search for fossilized life on Mars
While we go about our daily lives on Earth, a nuclear-powered robot the size of a small car is trundling around Mars looking for fossils. Unlike its predecessor Curiosity, NASA's Perseverance rover is explicitly intended to "search for potential evid.....»»
Enhanced CRISPR method enables stable insertion of large genes into the DNA of higher plants
Scientists at the Leibniz Institute of Plant Biochemistry (IPB) have succeeded for the first time in stably and precisely inserting large gene segments into the DNA of higher plants very efficiently. To do this, they optimized the gene-editing method.....»»
Argentine students protest funding cuts to public universities
Tens of thousands of Argentine university students took to the streets Tuesday to protest cuts to higher public education, research and science under budget-slashing new President Javier Milei......»»
Beyond higher temperatures: Preparing for national security risks posed by climate change
When talk turns to climate change, certain images pop to mind—maybe polar bears on ever-shrinking ice floes, coral reefs drained of color, or more powerful hurricanes hitting the coast......»»
Supercomputer simulation reveals new mechanism for membrane fusion
An intricate simulation performed by UT Southwestern Medical Center researchers using one of the world's most powerful supercomputers sheds new light on how proteins called SNAREs cause biological membranes to fuse......»»
Record electron temperatures for a small-scale, sheared-flow-stabilized Z-pinch fusion device achieved
In the nine decades since humans first produced fusion reactions, only a few fusion technologies have demonstrated the ability to make a thermal fusion plasma with electron temperatures hotter than 10 million degrees Celsius, roughly the temperature.....»»
Novel method could explore gluon saturation at the future electron-ion collider
The U.S. nuclear physics community is preparing to build the electron–ion collider (EIC), a flagship facility for probing the properties of matter and the strong nuclear force that holds matter together. The EIC will allow scientists to study how n.....»»
GM posts higher Q1 profit, ups 2024 financial guidance
GM said it raised its full-year earnings guidance and set a first-quarter record for North American revenue......»»
People doubt their own ability to spot AI-generated deepfakes
23% of Americans said they recently came across a political deepfake they later discovered to be fake, according to McAfee. The actual number of people exposed to political and other deepfakes is expected to be much higher given many Americans are no.....»»
The rising influence of AI on the 2024 US election
We stand at a crossroads for election misinformation: on one side our election apparatus has reached a higher level of security and is better defended from malicious attackers than ever before. On the other side, the rise of artificial intelligence (.....»»
Beta-decay measurements in mirror nuclei pin down the weak nuclear force
The Standard Model of Particle Physics is scientists' best understanding of the forces that describe how subatomic particles interact. The Standard Model encompasses four forces: the strong nuclear force, the weak nuclear force, the electromagnetic f.....»»
Mangrove blue carbon at higher risk of microplastic pollution
Earth's oceans and coastal ecosystems are a major sink for carbon storage, known as blue carbon. Sequestration of carbon is vitally important in the fight against climate change as it 'locks away' this molecule, alleviating pressure on greenhouse gas.....»»
Merging nuclear physics experiments and astronomical observations to advance equation-of-state research
For most stars, neutron stars and black holes are their final resting places. When a supergiant star runs out of fuel, it expands and then rapidly collapses on itself. This act creates a neutron star—an object denser than our sun crammed into a spa.....»»
