The Large Hadron Collider has been busy destroying protons by the billions. But now it’s set to do something completely different: generate miniature Big Bangs.
Scientists and researchers at CERN in Geneva are gearing up to launch experiments that attempt to recreate, as accurately as possible, the conditions immediately after the Big Bang, Discovery News reports. That could shed light on a state of matter that hasn’t existed in the known Universe for over 13.7 billion years.
Paleontologists from the United States and Canada have claimed that Tyrannosaurus Rex was a cannibal. The paleontologists analyzed marks and gouges on the fossils of the Tyrannosaurus Rex to conclude that the T-Rex was a cannibal. Researchers predicted that it was likely due to the scavenging rather than active hunting.
The T. Rex was the only large, late Cretaceous carnivore in Western North America, said the paleontologists. The findings were published in study titled “Cannibalism in Tyrannosaurus rex.” The research was done by Nicholas R. Longrich (Yale), John R. Horner (Montana State), Gregory M. Erickson (Florida State), and Philip J. Currie (University of Alberta).
New Earth-Like Goldilocks planet discovered by astronomers in alien solar system. The planet discovered is 20 light years from Earth with basic and essential conditions needed to support extraterrestrial life.
Earth-like exoplanets have been predicted for years by scientists in what is called the “habitable zone” around a star, but the identification and measurement of one has been called the beginning of a new era in the search for life beyond our galaxy.
“This is our first Goldilocks planet — just the right size and the right distance from its sun,” astronomer Paul Butler with the Carnegie Institution of Washington told The Washington Post. “A threshold has been crossed,” he said.
The new exoplanet, called Gliese 581G, is quite close at 20 light years from Earth.
Proof of extraterrestrial intelligence could come within 25 years, an astronomer who works on the search said Sunday.
“I actually think the chances that we’ll find ET are pretty good,” said Seth Shostak, senior astronomer at the Search for Extraterrestrial Intelligence Institute in Mountain View, Calif., here at the SETIcon convention. “Young people in the audience, I think there’s a really good chance you’re going to see this happen.”
SEOUL, South Korea – South Korean scientists say they have engineered four beagles that glow red using cloning techniques that could help develop cures for human diseases. The four dogs, all named “Ruppy” — a combination of the words “ruby” and “puppy” — look like typical beagles by daylight.
But they glow red under ultraviolet light, and the dogs’ nails and abdomens, which have thin skins, look red even to the naked eye.
Seoul National University professor Lee Byeong-chun, head of the research team, called them the world’s first transgenic dogs carrying fluorescent genes, an achievement that goes beyond just the glowing novelty.
“What’s significant in this work is not the dogs expressing red colors but that we planted genes into them,” Lee told The Associated Press on Tuesday.
His team identified the dogs as clones of a cell donor through DNA tests and earlier this month introduced the achievement in a paper on the Web site of the journal “Genesis.”
Since 1939, scientists have thought the “barreleye” fish Macropinna microstoma had “tunnel vision” due to eye that were fixed in place. Now though, Monterey Bay Aquarium researchers show that the fish actually has a transparent head and the eyes rotate around inside of it. From the Monterey Bay Aquarium Research Institute
(Bruce) Robison and (Kim) Reisenbichler used video from MBARI’s remotely operated vehicles (ROVs) to study barreleyes in the deep waters just offshore of Central California. At depths of 600 to 800 meters (2,000 to 2,600 feet) below the surface, the ROV cameras typically showed these fish hanging motionless in the water, their eyes glowing a vivid green in the ROV’s bright lights. The ROV video also revealed a previously undescribed feature of these fish–its eyes are surrounded by a transparent, fluid-filled shield that covers the top of the fish’s head.
Scientists believe they have cracked a long-standing mystery of evolution – how the turtle got its shell.
It follows the discovery in south west China last year of the oldest known turtle fossils, believed to date back 220 million years.
The three adult specimens were discovered remarkably intact and with characteristics never before seen in turtles – including teeth and an incomplete upper shell.
Scientists from Canada, China and the US said the half-shell provided new evidence of how it evolved, Nature magazine has reported.
Dr Xiao-chun Wu, a palaeontologist at the Canadian Museum of Nature in Ottawa, said: ‘Since the 1800s, there have been many hypotheses about the origin of the turtle shell.
CHICAGO (Reuters) – A new type of dry glue designed to mimic gecko feet is 10 times stickier than the gravity-defying lizards, and three times stickier than other gecko-inspired glues, U.S. researchers said on Thursday.
“It’s the stickiest dry glue yet,” said Liming Dai of the University of Dayton, who reported on the glue in the journal Science.
A 1-inch (2.5-cm) square of the adhesive can support the weight of a 220-pound (100-kg) man climbing up a vertical surface, but it can be easily lifted and reapplied, an ideal material for, say, a Spider-Man suit.
“That is not real. What we do is real,” said Zhong Lin Wang of Georgia Institute of Technology in Atlanta, referring to the comic book superhero’s wall-climbing prowess.
Aside from helping people walk up walls, the glue could be used in electrical components without the need for soldering, Wang and Dai said in a telephone interview.
Discovering a planet around another star is no big deal these days — dozens of them have been reported in 2008 alone, and the total count now stands at more than 300.
Of course, the burgeoning exoplanet population hasn’t stopped astronomers from looking for more of them. Big gaps remain in the sampling statistics, because the most successful techniques (radial-velocity monitoring, microlensing events, and periodic transits) favor finding large bodies close to their parent stars. Far-out planets are rarely discovered this way because they have long orbital periods and even longer odds of crossing directly in front of their stars.
But it should be possible to spot alien worlds directly by imaging very young nearby stars. This game plan assumes that any outlying gas-giant planets are still glowing warmly from their recent formation, making them relatively easy pickings at infrared wavelengths. One of these came to light in 2004, though it orbits a feebly glowing brown dwarf rather than a proper star.
