Physicists have placed a new limit on how big the elusive neutrino can be—one of the universe’s smallest known particles—a limit that makes other subatomic particles look as big as black holes by comparison. In a new result published this week in Science, researchers have put a new upper limit on the mass of this itsy-bitsy particle: no more than 0.45 electron volts (eV). For context, that’s less than one-millionth the mass of an electron, which clocks in at a comparatively gargantuan 511,000 e

When you swap two paraparticles, these hidden properties change in tandem. As an analogy, imagine that these properties are colors. Start with two paraparticles, one that’s internally red and another that’s internally blue. When they swap places, rather than keeping these colors, they both change in corresponding ways, as prescribed by the mathematics of the particular model. Perhaps the swap leaves them green and yellow. This quickly turns into a complex game, where paraparticles affect each ot

In particle physics, the smallest problems often require the biggest solutions. Along the border of France and Switzerland, around a hundred meters underneath the countryside, protons speed through a 27-kilometer ring—about seven times the length of the Indy 500 circuit—until they crash into protons going in the opposite direction. These particle pileups produce a petabyte of data every second, the most interesting of which is poured into data centers, accessible to thousands of physicists worl

The secret to the formation of planets may lie in ordinary static electricity—the same phenomenon that can make your hair stand on end or give you an electric shock after walking across a carpet. A new study, published in Nature Astronomy, suggests that static electricity allows tiny dust particles in protoplanetary disks—the rotating platters of gas and dust that form around young stars—to clump together into “pebbles” that are large enough to play a role in the formation of planets. The imag

To help inform our air purifier picks, we gathered 14 of the most popular models at the CNET Labs product testing facility in Louisville, Kentucky, where we put them through a rigorous set of tests. Our goal was to determine which air purifiers offered the best performance in terms of particle removal efficiency, energy consumption and quietness, while also evaluating their respective feature sets and value. The particle-removal test The air we breathe isn't just air. In truth, it's a combinat

The findings could help to explain the species’ fascinating flocking behaviour The CERN flock of sheep on site in 2017. (Image: CERN) Quantum entanglement is a fascinating phenomenon where two particles’ states are tied to each other, no matter how far apart the particles are. In 2022, the Nobel Prize in Physics was awarded to Alain Aspect, John F. Clauser and Anton Zeilinger for groundbreaking experiments involving entangled photons. These experiments confirmed the predictions for the manifes

Remote detection The ability to locate radioactive material at distances greater than the range of emitted particles could play an important role in nuclear disaster response and nuclear security. (Courtesy: Shutterstock/fewerton) Researchers have demonstrated that they can remotely detect radioactive material from 10 m away using short-pulse CO 2 lasers – a distance over ten times farther than achieved via previous methods. Conventional radiation detectors, such as Geiger counters, detect par

This week, a new technology was tested in Jõgisoo, Harju County, as part of a nearly €1.3 million research project. Using cosmic radiation and artificial intelligence, the technology aims to assess the technical condition of bridges without the need for destructive testing. Some drivers crossing the Jõgisoo Bridge this week may have wondered about the strange box placed on the structure. For those still curious, here's the answer — this was the world's first test of using cosmic radiation, spec

What is really going on in the quantum double-slit experiment? The question raised in this post’s title seems to lie at the heart of the matter. In this experiment, which I recently reviewed here, particles of some sort are aimed, one at a time, at a wall with two slits, and their arrival is recorded on a screen behind the wall. As a parade of particles proceeds, one by one, past the wall, an interference pattern somehow appears, emerging gradually like a spectre on the screen. Interference is

There's a new twist in the hunt for dark matter, the invisible substance believed to make up 85 percent of all the mass in the universe: it may actually be way lighter. In a study published in the journal Physical Review Letters, an international team of researchers propose a new form of the hypothetical substance that's lower in mass compared to other dark matter candidates, which could explain a mysterious phenomenon at the center of our Milky Way galaxy, in a region called the Central Molecu

In 2021 the Muon g-2 Experiment at Fermilab found a significant discrepancy between the theoretical prediction and the experimental measurement of the anomalous magnetic moment of the muon, indicating the existence of new physics.

By changing the composition of these materials’ building blocks, researchers can optimize properties such as hydrophobicity (ability to repel water), mechanical strength, and pH sensitivity. One property the team targeted, with an eye to using the polymer to add nutrients to food, was the ability to dissolve when exposed to acidic environments such as the stomach. The researchers showed that they could use particles of the polymer to encapsulate vitamins A, D, E, and C, as well as zinc and iron
