Watch Live: Higgs Boson Announcement

Officials at CERN will finally be revealing their latest results in the search for the Higgs boson during a talk starting at midnight PT (3 a.m. ET) on July 4.

Physicists have been eagerly waiting for this announcement, with hopes running high that the new data will pin down Higgs boson with enough precision to consider it discovered. Previously, LHC results have strongly signaled the existence of a Higgs with a mass of 125 gigaelectronvolts (GeV), or roughly 125 times more massive than the proton. More recently, rumors have been flying that suggest this talk will be the definitive announcement of the long-sought boson’s discovery.

Every physicist in the world — and likely thousands of interested laypeople — will be watching to see what CERN scientists announce. On his blog, physicist Tommaso Dorigo, who works with one of the main Higg-hunting experiments at the LHC, described the scene in the lecture hall the day before the talk:

“Analyzers are feverishly giving the last touches to the most important graphs, unfortunately exactly the ones that took the most time to put together. Conveners are busy producing text for the press conferences and interviews, and translating them to all known languages on Earth. Spokespersons are overburdened with the task of producing well-balanced talks which will be broadcasted worldwide and which will probably make history.”

Much of the talk will be presented in dense jargon, accessible only to particle physicists. If you need help unpacking it all, check out the physicists liveblogging the event, including Aidan Randle-Conde from Southern Methodist University and Sean Carroll from Caltech. Randle-Conde will also be giving a post-talk wrap-up with physicist Stephen Sekula. And if you just need a yes or no answer after all this anticipation, check out havewefoundthehiggsyet.com.

 

Watch a Livestream of the Higgs Boson Announcement Tonight

Update: The live feed is now available.

Scientists at CERN will announce their most recent results in the search for the Higgs boson early on July 4 — with many speculating that the discovery of the long-sought particle will finally be official.

Join us here for a live feed from Europe of the event starting at 11 p.m PT tonight (2 a.m. ET). The announcement of results is expected to begin at midnight PT, featuring spokesmen from the Large Hadron Collider’s two Higgs-hunting experiments, ATLAS and CMS, followed by a press conference and question-and-answer session.

Rumors have been flying for weeks already on what the LHC has found, with most pointing to a discovery of the Higgs boson with a mass of 125 gigaelectronvolts (GeV).

Peter Higgs and several other physicists theorized about the Higgs boson in the 1960s, though it is only in recent decades that machines powerful enough to search for it have been built. If the particle is discovered, it will be the final piece of the Standard Model of physics, which describes the interactions of all particles and forces.

Many physicists are hoping that the Higgs announcement will include details about its properties and why it doesn’t exactly fit in with the Standard Model’s predictions. If so, it could point to new physics beyond the Standard Model, such as supersymmetry, though thus far no firm evidence for this has been observed. It may take several more years of searching at high energies to confirm or exclude different advanced theories.

Several physicists will be liveblogging the announcement with commentary for those in need of help following the convoluted jargon, including Aidan Randle-Conde from Southern Methodist University and Sean Carroll from Caltech. Randle-Conde will also be giving a post-talk wrap-up with physicist Stephen Sekula.

Leaked Video Appears to Accidentally Announce Higgs Boson Discovery

                    

A video accidentally published on the CERN website appears to leak the long-awaited discovery of the Higgs boson that is rumored to be officially announced early tomorrow morning.

“We’ve observed a new particle. We have quite strong evidence that there’s something there. Its properties are still going to take us a little bit of time,” Joe Incandela, spokesman for the CMS experiment, one of the main Higgs-searching experiments at CERN’s Large Hadron Collider, said in the video. “We think this is pretty darned significant.”

Incandela stops short of calling the new particle the Higgs in the video, saying the results are preliminary. And a CERN press officer told the Telegraph that the video is merely one of several videos made for different possible outcomes in preparation for their big announcement, scheduled for 12 a.m. PDT tomorrow morning. The video has since been removed from the website.

But the buzz surrounding the announcement, coupled with Fermilab announcing its final Higgs search results from the Tevatron yesterday, the fact that six physicists who theorized about the Higgs particle back in the 1960s – including the particle’s namesake, Peter Higgs –  were invited by CERN to attend the announcement, and now the leaked video, strongly suggest that the Higgs discovery is finally about to be unveiled.

If the particle Incandela mentions is indeed the Higgs boson, physicists will be most excited to learn if its properties are those predicted under the Standard Model, or if they indicates the presence of new physics. Regardless of what it is, the finding seems to have physicists all fired up.

“I think this video is very exciting, though we’ll get more details when the data comes out,” said theoretical physicist Mark Wise from Caltech.

Exposure to Dogs Could Protect Kids From Asthma

By Liat Clark, Wired UK

Babies exposed to certain microbes carried by dogs may build up immunity against asthma, according to research by a team of biologists from the University of California.

Wired U.K.
The hypothesis was announced at the General Meeting of the American Society for Microbiology. Having already proven that the microbiome of dust from homes that have pets is distinct from dust in pet-free homes, the biologists decided to find out if this knowledge had any practical applications.

After exposing mice to dust from homes that have dogs, then to the respiratory syncytial virus (RSV) — a virus common in infants and associated with a high risk of developing asthma in childhood — the team found that the mice were immune to the virus. The biologists used three test groups in the study — mice exposed to RSV, mice exposed to RSV and house dust and mice exposed to neither.
