The 2015 Nobel Prize in physics goes to Takaaki Kajita and Arthur B. McDonald for their work on neutrino oscillations. By tracking neutrinos in subterranean water tanks, the researchers watched neutrinos change flavour, in turn proving that the subatomic particles have mass.
In the 1950s, two physicists decided that they would find the elusive “neutrino” they’d heard so much about. They did find it — just not the way they first thought they would. And since they thought they would find it by exploding a nuclear bomb, that’s a good thing.
If you are using the Holborn Tube Station in England, you are getting to work via the site of an important part of physics history. It was home to an experiment that moved physics literally underground for the first time, all in the search for the elusive neutrino.
It was the heady days of the early 1900s, and radiation was all the rage. Researchers had just found a kind of radiation called "beta decay," and they discovered that it did something that seemed to smash one of the basic tenets of physics. Here's how the lowly neutrino saved the entire field.
Neutrinos are the ninjas of the universe. They don't interact with other particles very often, but when they do, they obliterate them. Until now. Scientists have observed a new way that neutrinos interact with the world.
It may seem as though every new day brings an announcement of a scientific breakthrough of the highest order. Should you freak out about every new record-breaking neutrino? In this week's "Ask a Physicist," we'll find out.
From intergalactic neutrinos and invisible brains, to the creation of miniature human "organoids," 2013 was a remarkable year for scientific discovery. Here are 17 of the biggest scientific breakthroughs, innovations and advances of 2013.
Italian physicists want to use 2,000 year-old lead ingots recovered from a Roman shipwreck to investigate the properties of dark matter and neutrinos. Roman lead is perfect for conducting such experiments owing to their purity and low levels of radioactivity. But archaeologists say it's ethically questionable research…
By drilling a 1.5 mile hole deep into an Antarctic glacier, physicists working at the IceCube South Pole Observatory have captured 28 extraterrestrial neutrinos — those mysterious and extremely powerful subatomic particles that can pass straight through solid matter. Welcome to an entirely new age of astronomy.
The title of the paper: "Can apparent superluminal neutrino speeds be explained as a quantum weak measurement?" The abstract? See for yourself:
A couple months ago, scientists with IceCube, an Antarctica-based neutrino observatory, discovered two very high-energy neutrinos — named Bert and Ernie — that appeared to have originated from beyond our solar system. This is amazing news, and we talked to the researchers about what it means.
Foolish humans. Such hubris to think that we could dethrone Einsteinian special relativity, by virtue of a single experiment. Now it's official: the notion that neutrinos could travel faster than the speed of light really was the result of a "faulty kit".
Neutrinos may not travel faster than light, but that doesn't mean they can't be put to good use. By sending encoded pulses of neutrinos on a 10,000 km shortcut directly through the Earth, financial firms and high-frequency trading companies think they can get a 44-millisecond communication advantage over their…
On the morning of September 22, 2011, OPERA spokesperson Antonio Ereditato announced to the world that members of the OPERA experiment had observed neutrinos traveling faster than the speed of light. The next day, experimental coordinator Dario Autiero presented the team's findings at an internationally broadcasted…
Every year, in memory of Isaac Asimov, the American Museum of Natural History invites leading scientists from around the world to debate the finer points of questions and problems that are emerging at the frontiers of scientific discovery.
Yesterday, rumors were circulating that last year's faster-than-light neutrino results had been undone by a simple mechanical mishap: one of the fiber optic cables connecting a GPS unit to a computer may have been loose.
This could be it, folks. Last September, physicists watching neutrinos travel from the CERN laboratory in Switzerland to Italy's Gran Sasso laboratory announced that they had detected the subatomic particles making the trip 60 nanoseconds faster than the speed of light dictates is possible. Now, rumors are flying that…
When physicists announced in September that they had observed neutrinos traveling faster than the speed of light, the scientific community was justifiably skeptical.
Amidst the dubious news of neutrinos potentially traveling faster than light, it's easy to lose sight of something even stranger: neutrinos are in a constant identity crisis, oscillating between different types. Why is this? In this week's "Ask a Physicist" we'll find out.
