    Scientists just outside Chicago have found that the mass of a sub-atomic particle is not what it should be. The measurement is the first conclusive experimental result that is at odds with one of the most important and successful theories of modern physics. The team has found that the particle, known as a W boson, is more massive than the theories predicted. The scientists at the Fermilab Collider Detector (CDF) in Illinois have found only a tiny difference in the mass of the W Boson compared with what the theory says it should be - just 0.1%. But if confirmed...

    Microplastics – tiny pieces of plastic less than 0.2 of an inch (5mm) in diameter – have been found in human blood for the first time. Scientists in the Netherlands took blood samples from 22 anonymous healthy adult donors and analysed them for particles as small as 0.00002 of an inch. The researchers found that 17 out of the 22 volunteers (77.2 per cent) had microplastics in their blood – a finding described as 'extremely concerning'.

    Kanagawa Prefecture in Japan put a batch of Moderna’s COVID-19 vaccine on hold after a pharmacist found foreign matter in one of the vials. The story: Japanese authorities reported that a pharmacist looked at the vial before administering the shot and saw several black particles. The vaccine’s domestic distributor, Takeda Pharmaceutical Co Ltd, collected the vial with the suspected contaminant and the Japanese government put the rest of the batch on hold as they investigate the case. About 3,790 people had already received the shot. The big picture: Just last week, Japan halted the use of 1.63 million doses of...

    The death of this reigning physics paradigm, the Standard Model, has been predicted for decades. There are hints of its problems in the physics we already have. Strange results from laboratory experiments suggest flickers of ghostly new species of neutrinos beyond the three described in the Standard Model. And the universe seems full of dark matter that no particle in the Standard Model can explain. But recent tantalizing evidence might one day tie those vague strands of data together: Three times since 2016, ultra-high-energy particles have blasted up through the ice of Antarctica, setting off detectors in the Antarctic Impulsive...

    NASA has shared a spectacular picture of the Northern Lights adorning the sky in Iceland - but warned that the "beauty and the beast" aurora could wreak havoc here on Earth. The image was captured by astronomer Juan Carlos Casado in 2016, and selected as NASA's Astronomy Picture of the Day on Sunday. It shows the aurora borealis over Thingvallavatn Lake in Iceland - a lake that partly fills a fault that divides Earth's large Eurasian and North American tectonic plates. "Admire the beauty but fear the beast," wrote Casado, in his picture caption. The beauty is the aurora overhead,...

    CERN wants to go super-sized. The particle physics lab near Geneva in Switzerland has just unveiled its plans for a replacement for the Large Hadron Collider (LHC). The news: CERN has released a design report for the Future Circular Collider, which would be four times as big as the LHC. Colliders send particles around a loop at incredible speeds and then let researchers analyze the fallout when they smash into one another. The design for the FCC would be some 100 kilometers (62 miles) long and, when operating at full capacity, collide particles at 10 times the energy of the...

    Cosmic rays emanating from the south polar ice cap could lead to new physics There’s something mysterious coming up from the frozen ground in Antarctica, and it could break physics as we know it. Physicists don’t know what it is exactly. But they do know it’s some sort of cosmic ray—a high-energy particle that’s blasted its way through space, into the Earth, and back out again. But the particles physicists know about—the collection of particles that make up what scientists call the Standard Model (SM) of particle physics—shouldn’t be able to do that. Sure, there are low-energy neutrinos that can...

    In this mini world, the concepts of "before" and "after" dissolve, such that two events can both precede and succeed each other. In other words, event A can occur before event B, and event B can occur before event A... This idea, called a "quantum switch," was first proposed in 2009 by another team and has since been explored both theoretically and experimentally. Previous experiments showed event A could both precede and succeed event B, but the research couldn't say that these two scenarios were happening at the same place, said Cyril Branciard, co-author of this new study and a...

    Pip-squeak particles called neutrinos are dishing out more than scientists had bargained for.A particle detector has spotted a puzzling abundance of the lightweight subatomic particles and their antimatter partners, antineutrinos, physicists report May 30 at arXiv.org. The finding mirrors a neutrino excess found more than two decades ago. And that match has researchers wondering if a new type of particle called a sterile neutrino — one even more shadowy than the famously elusive ordinary neutrinos — might be at large.Such a particle, if it exists, would transform the foundations of particle physics and could help solve cosmic puzzles like the...

    Scientists are ecstatic over the fact that they may have just discovered the fifth fundamental force of nature. The possible discovery of a previously-unknown subatomic particle looks set to finally bring the elusive dark matter into the mix. The discovery centers on a new type of boson that possesses characteristics previously unseen in particles. Furthermore, its existence casts doubt upon whether the known ‘sector’ of matter and particles exists alongside a ‘dark’ sector – both interacting with each other via another, unseen force.“If true, it's revolutionary,” said Jonathan Feng, professor of physics & astronomy at the University of California, Irvine,...

    Can you imagine a future where your car is fueled by iron powder instead of gasoline? Metal powders, produced using clean primary energy sources, could provide a more viable long-term replacement for fossil fuels than other widely discussed alternatives, such as hydrogen, biofuels or batteries, according to a study in the Dec. 15 issue of the journal Applied Energy. "Technologies to generate clean electricity -- primarily solar and wind power -- are being developed rapidly; but we can't use that electricity for many of the things that oil and gas are used for today, such as transportation and global energy...

    The gigantic accelerator in Europe has produced hints of an exotic particle that defies the known laws of physics. A little wiggle on a graph, representing just a handful of particles, has set the world of physics abuzz. Scientists at the Large Hadron Collider (LHC) in Switzerland, the largest particle accelerator on Earth, reported yesterday that their machine might have produced a brand new particle not included in the established laws of particle physics known as the Standard Model. Their results, based on the data collected from April to November after the LHC began colliding protons at nearly twice the...

    The Universe we know and love - with Einstein's General Relativity as our theory of gravity and quantum field theories of the other three forces - has a problem that we don't often talk about: it's incomplete, and we know it. Einstein's theory on its own is just fine, describing how matter-and-energy relate to the curvature of space-and-time. Quantum field theories on their own are fine as well, describing how particles interact and experience forces. Normally, the quantum field theory calculations are done in flat space, where spacetime isn't curved. We can do them in the curved space described by...

    They can theoretically carry charge 1,000 times faster than ordinary electrons. After 85 years of searching, researchers have confirmed the existence of a massless particle called the Weyl fermion for the first time ever. With the unique ability to behave as both matter and anti-matter inside a crystal, this strange particle can create electrons that have no mass. The discovery is huge, not just because we finally have proof that these elusive particles exist, but because it paves the way for far more efficient electronics, and new types of quantum computing. "Weyl fermions could be used to solve the traffic...

    The new Majorana particle showed up inside a superconductor, a material in which the free movement of electrons allows electricity to flow without resistance. The research team, led by Ali Yazdani of Princeton University, placed a long chain of iron atoms, which are magnetic, on top of a superconductor made of lead. Normally, magnetism disrupts superconductors, which depend on a lack of magnetic fields for their electrons to flow unimpeded. But in this case the magnetic chain turned into a special type of superconductor in which electrons next to one another in the chain coordinated their spins to simultaneously satisfy...

    Particle physicists at the European Organization for Nuclear Research announced 2 years ago they had discovered the Higgs particle, considered the foundation particle in the Standard Model of Particle physics, and a Nobel Prize was awarded to Peter Higgs and Francois Englert for their work on the theory of the Higgs boson. Now, though, researchers at the University of Southern Denmark's Center for Cosmology and Particle Physics Phenomenology suggest that while the CERN scientists did discover a unique new particle, there's no conclusive evidence of it being the Higgs boson. The Higgs could explain data obtained by CERN scientists using...

    Mystery Over Shiny Particles On Mars Gets More Exciting Dina SpectorOct. 17, 2012, 12:32 PM NASA NASA's Curiosity rover had been on Mars 61 days when she gathered her first scoop of soil. Before the one-ton robot could finish sifting through her first small bucket of dust, however, all the excitement shifted to a shiny object found in the sand near the rover. After reviewing images, the Curiosity team determined that the bright material was probably a piece of plastic from the rover and not material from Mars. Or so they thought. The rover collected its second scoop of Martian...

    If we have free will, so do subatomic particles, mathematicians claim to prove.“If the atoms never swerve so as to originate some new movement that will snap the bonds of fate, the everlasting sequence of cause and effect—what is the source of the free will possessed by living things throughout the earth?”—Titus Lucretius Carus, Roman philosopher and poet, 99–55 BC. Human free will might seem like the squishiest of philosophical subjects, way beyond the realm of mathematical demonstration. But two highly regarded Princeton mathematicians, John Conway and Simon Kochen, claim to have proven that if humans have even the tiniest...
