The authenticity of the Shroud of Turin has been in question for centuries and scientific investigations over the last few decades have only seemed to muddle the debate. Is the revered cloth a miracle or an elaborate hoax?
Now, a study claims neutron emissions from an ancient earthquake that rocked Jerusalem could have created the iconic image, as well as messed up the radiocarbon levels that later suggested the shroud was a medieval forgery. But other scientists say this newly proposed premise leaves some major questions unanswered.
Black holes are vexing objects. Not only do they defy our everyday understanding about how the Universe should work, they confound even the most complex mathematical models. Science writers describe them as “gravitational behemoths” that warp spacetime so much that even light cannot escape the surrounding boundary, known as the “event horizon.” But what lies inside? Well, that doesn’t matter, we argue, everyday physics does not apply once you cross the event horizon.
The horribly unsatisfactory explanation has been battered in recent months when a serious physics confrontation entered the public arena. What goes on inside a black hole’s event horizon has actually caused a theoretical conflagration and now, two theoretical physicists have proposed a new idea that may marry quantum mechanics with gravity, extinguishing the tricky “firewall” and finding a solution to the “information paradox.”
Copenhagen Zoo employees on Sunday killed a young male giraffe named Marius because he wouldn’t serve as good breeding stock. On Sunday morning, the animal was fed to lions after being euthanized with a bolt gun then dissected in public. Zoo officials explained their decision on the zoo’s website and to the press. Read more
Years of planning and billions of dollars went into the 2014 Winter Olympic Games in Sochi. Selected as the venue in 2007, Russia is host to the Olympics for the first time since the break-up of the Soviet Union. The last Olympics held within its borders was the 1980 Winter Olympics in Moscow.
Despite all the time, money and effort, Russia isn’t looking all too ready for the start of competition in just a matter of days. In fact, the most expensive Olympics in history may even turn out to be a disaster. Read more
8 NFL Facts That Will Piss You Off During The Super Bowl
This Sunday, 169 million people are expected to watch Super Bowl, which will be broadcast in more than 30 languages to 180 different countries. With numbers like these, it’s no surprise that football is America’s most popular sport and the NFL is the most profitable sports league in the world.
But behind the curtain of the Big Game’s glitz and glamour is a league plagued by controversy, most notably the NFL’s refusal to acknowledge the correlation between football and brain damage. Mark Fainaru-Wada, ESPN reporter and co-author of the book “League of Denial,” which chronicled two decades of the league’s malfeasance on the issue, said he was struck by the NFL’s profound level of denial and the lengths to which it went to refuse responsibility.

A new cache of extremely well preserved, prehistoric canine fossils is shedding light on dog and wolf ancestors from 2 million years ago to today.
The fossils, described in the latest issue of the Journal of Mammalian Evolution, date to that early period and belonged to a scrappy canine carnivore known as Canis etruscus that lived near Rome, Italy.
“Canis etruscus appeared approximately 2 million years ago and is the oldest European species referred to in the genus Canis,” lead author Marco Cherin told Discovery News, adding that this species “was considerably smaller than the modern wolf.” Read more
Over the millions of years that plants have evolved, they’ve reacted to multitudes of stimuli for the sheer fact that they can’t get up and walk away. In doing so, vegetation releases tell-tale electrical signals that researchers believed can be harnessed to effectively turn plants into biosensors. Read more
Astronomers analyzing data from the now defunct Herschel infrared space observatory have made a huge discovery deep inside the asteroid belt. Dwarf planet Ceres, the largest body in the region, is generating plumes of water vapor. Read more
