UPDATE on Abused Horse
This is April Foster...she was arrested yesterday for punching a police horse during last weekend's Trump rally.
PETA has responded to an incident involving Donald Trump protester April Foster, who was arrested Friday in Kansas City after she was seen beating a police horse.
“All animals feel pain, stress and fear just like we do, and they deserve our respect and protection,” said PETA Senior Vice President Tommi Uk in a statement on the incident. “Horses are highly sensitive prey animals, and this poor horse was without a doubt already under a tremendous amount of stress as a result of the chaos, the crowds, the deafening noise of the angry protesters, and more.”
PETA commends the person who called the tip line so that this woman’s apparent cruelty to this horse does not go unpunished,” the PETA statement said. " This reporter spoke to April as she was handcufffed .."the horse said something dirty to me and tried to snort up where it had no business! That fat cop riding him should be arrested too for cruelty ...look at him" Replay of the several cameras did not reveal anything unusual however..
In Foster’s Instagram bio (now deleted), the individual (who apparently identifies as ‘transgender’) describes him/herself as a “commie feminist”.

Higgs' Big Brother??
Here we go again! I'm getting another headache!
Bump in Large Hadron Collider data has physicists electrified
Date: March 21, 2016 Source: Fermi National Accelerator Laboratory (Fermilab)
In December, the ATLAS and CMS experiments presented a sneak peek of the new data collected during the first few months of the Large Hadron Collider's enormously energetic second run. Both experiments reported a small excess of photon pairs with a combined mass around 750 GeV. This small excess could be the first hint of a new massive particle that spits out two photons as it decays, or it might be a coincidental fluctuation that will disappear with more information.
Now, physicists are presenting their latest analyses at the Moriond conference in La Thuile, Italy, including a full investigation of this mysterious bump. After carefully checking, cross-checking and rechecking the data, both experiments have come to the same conclusion -- the bump is still there.
"We've re-calibrated our data and made several improvements to our analyses," says Livia Soffi, a postdoc at Cornell University. "These are the best, most refined results we have. But we're still working with the same amount of data we collected in 2015. At this point, only more data could make a significant difference in our ongoing research."
LHC physicists wield a myriad of powerful tools to investigate the mysteries of the universe: a 17-mile-long particle accelerator; huge and intricate particle detectors; a worldwide network of computing centers. But from all these resources, there's one tool that can make or break any potential discovery -- statistics.
In 2015, LHC scientists recorded data from 20 trillion proton-proton collisions. A few tens of thousands of these collisions simultaneously produced a high-energy and clean pair of photons. Around 1200 of these photon pairs have a combined energy of 125 GeV (scientists now know that Higgs Bosons spat-out about 100 of them. The other 1100 were produced by normal and well known processes.) Moving towards higher energies, the spectrum starts to fluctuate more and more as there are fewer and fewer pairs recorded. At around 750 GeV, scientists observed only a few dozen photon pairs, and a handful more than predicted.
But whether this extra handful is evidence of a new particle or just another normal statistical fluctuation is essentially a coin toss.
"In physics we sometimes see excesses due to statistical fluctuations as we go up to higher and higher energies," says Massimiliano Bellomo, a postdoc at the University of Massachusetts, Amherst. "We're currently at the very edge of our sensitivity and cannot confirm or exclude any of the bumps we're watching until we have much more data."
On its own, one small bump means nothing. But excitement builds when independent experiments start to see the same bump popping up over and over again.
"I saw this fluctuation while doing my PhD thesis with CMS data from Run 1 and didn't think anything of it," Soffi says. "Now CMS and ATLAS have both seen it again in the new data. This could easily be a coincidence. But if it keeps showing up, then we might have something."
For their new analysis, the CMS experiment incorporated about 20 percent more data -- data that was recorded during Run 2 when the CMS magnet was turned off. They also recalculated the energies of particles recorded by the detector using more refined calibrations. After integrating these two improvements into their analysis, CMS is still seeing the bump; and it's slightly more pronounced than before.
ATLAS scientists are also delving deeper into this mystery. This week they re-examined data collected from the first run of the LHC to see if this recalcitrant bump would make yet another appearance. Scientists performed two independent searches, each employing a slightly different method to classify and separate the photon pairs. In one analysis, scientists again saw a small excess of photons pairs at 750 GeV. But in the other analysis, they saw nothing out of the ordinary. A further investigation of the 13 TeV data from 2015 shows that the bump is still there, but still not significant.
"The bottom line is that we can't say anything definitive until we have more data," says Beate Heinemann, a researcher at the US Department of Energy's Berkeley Laboratory and deputy spokesperson for the ATLAS experiment. "Therefore we are now focusing on getting ready to record and analyze the large amount of data that the LHC will deliver this year."
Even with the limited amount of data, physicists are already looking ahead and speculating what this little bump could be if it grows over time. A popular and emerging theory is that it could be the first glimpse of a heavier cousin of the Higgs boson.
"We have discovered one Higgs boson with a mass of 125 GeV," says Andrei Gritsan, a professor of physics at Johns Hopkins University. "We are trying to understand this boson deeper, but at the same time we are looking for other possible Higgs bosons with higher masses. We are excited about the excess at 750 GeV in one decay channel, but we need to establish if this signal is real and if it appears anywhere else before we can say something about it. All we can do today is hypothesize and speculate."
