Credit: CERN Atmospheric aerosol particles exert a strong net cooling effect on the climate by making clouds brighter and more extensive, reflecting more sunlight back out to space. However, how aerosol particles form in the atmosphere remains poorly understood, especially in polar and marine regions. Globally, the main…

WASHINGTON, D.C.—U.S. physicists have a bold new plan to “explore the quantum universe,” from the smallest bits of matter to the broadest reaches of the cosmos.On December 7 the Particle Physics Project Prioritization Panel (P5), a committee of experts that convenes roughly once a decade, debuted its draft report, which charts a course for U.S. particle physics across the next two decades. “What we are really after is: ‘How does the universe work?’” says Hitoshi Murayama, chair of P5 and a theorist at the University of…

Particle accelerators are hugely useful in scientific research, but – like the Large Hadron Collider (LHC) – usually take up vast amounts of room. A remarkable new system developed at the University of Texas in Austin could change this.In experiments, researchers were able to use their particle accelerator to generate an electron beam with an energy of 10 billion electron volts (10 GeV) in a chamber measuring just 10 centimeters (4 inches).The complete instrument measures 20 meters (66 feet) from end to end. In…

The USA has only two accelerators that can produce 10 billion electron-volt particle beams, and they're each about 1.9 miles (3 km) long. "We can now reach those energies in 10 cm (4 inches)," said the CEO of TAU Systems, which has built an ultra-compact accelerator. Well, that's the length of the helium-filled gas chamber where the actual acceleration occurs in the device TAU has recently tested. This compact advanced wakefield accelerator also requires a monster of a laser to run – in this case, the Texas Petawatt…

Long before symptoms of neurodegeneration appear, the brain's tissues are slowly failing under a barrage of chemical assaults.Reinforcing our nervous system against such attacks requires smuggling some kind of protection across a formidable boundary called the blood-brain barrier.A tiny particle made from compounds found in discarded coffee grinds just might be up to the job.Researchers from The University of Texas at El Paso (UTEP) demonstrated in lab tests their specially formulated material was more than capable of…

Astronomers discovered a high-energy cosmic particle named “Amaterasu,” with an unprecedented energy level of 244 EeV, using the Telescope Array experiment in Utah. This rare cosmic ray, comparable to the historic “Oh-My-God” particle, raises questions about its origin and composition.Unknown extremely energetic particle from space detected and named after Japanese myth.A high-energy particle falls from space to the Earth’s surface—it is not clear where it came from or even what it is, exactly. This may sound like…

New research highlights the risks posed by space radiation to lunar and Martian exploration, focusing on a recent Solar Energetic Particle event. It underscores the varying levels of natural protection against such radiation on Earth, the Moon, and Mars, and stresses the importance of developing effective shielding for astronaut safety in future space missions.Space radiation poses a significant challenge to humanity’s ambitions in space exploration, particularly in missions to the Moon and Mars. This radiation, primarily…

Decades ago, regulations for laboratory maintenance were not quite as stringent as they are today. This, we assume, is at least partially what led the great minds at what was then the US National Accelerator Laboratory, now Fermilab, to an ingenious solution for cleaning a particle accelerator back in 1971.It was February. The Main Ring particle accelerator at the NAL's Meson Laboratory was fresh out of the wrapper, and physicists were keen to start running it through its paces.This $250 million piece of equipment…
