Scientists at the Large Hadron Collider have announced the discovery of a new particle called the pentaquark.
It was first predicted to exist in the 1960s but, much like the Higgs boson particle before it, the pentaquark eluded science for decades until its detection at the LHC. The discovery, which amounts to a new form of matter, was made by the Hadron Collider's LHCb experiment.
The findings have been submitted to the journal Physical Review Letters.
Large Hadron Collider discovers new pentaquark particle
Perpetual war creates endless consequences
When the outgoing chairman of the Joint Chiefs of Staff, Gen. Martin Dempsey, began this month by issuing a farewell report on U.S. military strategy, the gist was hardly big news. “Dempsey to Pentagon: Prepare for the Never-Ending War” read the headline on the cover page of the National Journal.
The “war on terror” now looks so endless that no one speculates anymore about when it might conclude. “This war, like all wars, must end,” President Barack Obama declared in a major speech more than two years ago. “That’s what history advises. That’s what our democracy demands.” But midway through 2015, this war seems as interminable as ever.
'One of the largest human experiments in history' was conducted on unsuspecting residents of San Francisco
San Francisco's fog is famous, especially in the summer, when weather conditions combine to create the characteristic cooling blanket that sits over the Bay Area.
But one fact many may not know about San Francisco's fog is that in 1950, the US military conducted a test to see whether it could be used to help spread a biological weapon in a "simulated germ-warfare attack." This was just the start of many such tests around the country that would go on in secret for years.
Psychologists Shielded CIA Torture
The Central Intelligence Agency’s health professionals repeatedly criticized the agency’s post-Sept. 11 interrogation program, but their protests were rebuffed by prominent outside psychologists who lent credibility to the program, according to a new report.
The 542-page report, which examines the involvement of the nation’s psychologists and their largest professional organization, the American Psychological Association, with the harsh interrogation programs of the Bush era, raises repeated questions about the collaboration between psychologists and officials at both the C.I.A. and the Pentagon.
After 54 years, Confederate flag removed from Statehouse
The Confederate flag was lowered from the grounds of the South Carolina Statehouse on Friday, ending its 54-year presence there and marking a stunning political reversal in a state where many thought the rebel banner would fly indefinitely.
The turnabout seemed unthinkable before the June 17 massacre of nine black parishioners — including a state senator — at a Charleston church during a Bible study. Dylann Roof, a white man who was photographed with the Confederate flag, is charged in the shooting deaths, and authorities have called the killings a hate crime.
The massacre reignited calls to remove Confederate flags and symbols across the South and around the nation.
New Horizons snaps Pluto from eight million km
New Horizons has acquired yet another stunning view of Pluto.
The US space agency probe captured the latest image on Tuesday when it was just under eight million km from the dwarf world.
As of Thursday, New Horizons had moved to within six million km, heading for its historic flyby next week.
US allows cruises to Cuba; Carnival plans trips from Miami in May
The U.S. has authorized the first cruise service to Cuba in half a century.
Cruise giant Carnival Corp. announced Tuesday that it has received U.S. government licenses to offer "purposeful" cruises from the U.S. to Cuba for people-to-people, humanitarian and other exchanges.
Pending approval from Cuban authorities, Carnival aims to offer seven-day trips from Miami to several Cuban ports starting in May on its new "fathom" brand, which offers travel for social causes such as volunteer work and cultural immersion.
Alex Baer: Ka-Boom -- Happy Hangover Day.
July Fifth: July Fourth, plus one, and counting. Happy Hangover Day, gunpowder aficionados.
(I'll bet many of you are thinking that the rest of us are admiring the many black marks of your scorched-earth policies on the sidewalks and roadways of our Freedom. Actually, we are not. No, we're frankly puzzled, looking down at those gunpowdered starbursts, how it is that primates have toddled and dawdled along this far. We're amazed that this universe has treated so well the unlikely equation of Curiosity + Opposable Thumbs + Tool-making Ability, and how it got us this species, ourselves, us -- how it got us anywhere at all, let alone not having gotten us smeared, long ago, across the landscape of our own night terrors.)
And now, an update on terrorism:
Russian craft delivers long-awaited cargo to space station
An unmanned Russian cargo ship has docked successfully at the International Space Station, where it was anxiously awaited by the U.S.-Russian crew after the successive failures of two previous supply missions.
The Progress M-28M ship, which is carrying 2.5 metric tons of fuel, oxygen, water, food and other supplies, was launched into orbit on Friday from the Baikonur launch pad in Kazakhstan. Russian Mission Control said it docked successfully Sunday in the automated mode at the orbiting space station.
