Topological Matter in Optical Lattices. Comet Collisions Fuel Star's Oddly Young Look. A cosmic mystery around the star named 49 CETI has puzzled astronomers nearly two decades, but it may finally be solved.
At 40 million years old, the star is quite ancient, and yet it's surrounded by a tremendous amount of gas — a signature feature of young stars that usually fades within 10 million years, scientist say. So what keeps 49 CETI looking young?
Joem 4. Joem 3. Rare Particle Find May Cast Doubt on Popular Physics Theory. An extremely rare particle measurement from the world's largest atom smasher could cast doubt on a popular theory about the fundamental building blocks of the universe, including dark matter.
Physicists from the Large Hadron Collider (LHC) in Switzerland have measured a particular type of particle transformation for the first time, and found that it happens just about as often as predicted by the dominant theory of particle physics, called the Standard Model. The measurement is just preliminary — the researchers haven't collected enough data to be positive what they're seeing isn't just a random occurrence. Still, the fact that the initial observations correspond so well with the Standard Model predictions isn't a hopeful sign for what scientists call "new physics," such as new particles not predicted by the Standard Model.

Are Humans Losing Their Smarts? Humans may be gradually losing intelligence, according to a new study.
The study, published today (Nov. 12) in the journal Trends in Genetics, argues that humans lost the evolutionary pressure to be smart once we started living in dense agricultural settlements several thousand years ago. "The development of our intellectual abilities and the optimization of thousands of intelligence genes probably occurred in relatively non-verbal, dispersed groups of peoples [living] before our ancestors emerged from Africa," said study author Gerald Crabtree, a researcher at Stanford University, in a statement. Since then it's all been downhill, Crabtree contends. Are Humans Becoming Less Intelligent? Humans may be gradually losing intelligence, according to a new study.

Since then it's all been downhill, Crabtree contends. The theory isn't without critics, with one scientist contacted by LiveScience suggesting that rather than losing our smarts, humans have just diversified them with various types of intelligence today.

Private Deep Space Asteroid Telescope Mission to be Unveiled June 28. UPDATE: The B612 Foundation has revealed the details of their asteroid-hunting Sentinel Space Telescope to the world.
See the full story, plus images and a gallery, here: World's 1st Private Deep-Space Telescope to Hunt Dangerous Asteroids A group of scientists will unveil an audacious plan for the first privately funded deep space telescope next week - a mission that aims to map the inner solar system for potentially dangerous asteroids. On June 28, members of the B612 Foundation will discuss plans to build, launch and operate the Sentinel Space Telescope Mission during a press conference at the Morrison Planetarium at the California Academy of Sciences in San Francisco. Misbehaving Particles Poke Holes in Reigning Physics Theory. The reigning theory of particle physics may be flawed, according to new evidence that a subatomic particle decays in a certain way more often than it should, scientists announced.
This theory, called the Standard Model, is the best handbook scientists have to describe the tiny bits of matter that make up the universe. But many physicists suspect the Standard Model has some holes in it, and findings like this may point to where those holes are hiding. Inside the BaBar experiment at the SLAC National Accelerator Laboratory in Menlo Park, Calif., researchers observe collisions between electrons and their antimatter partners, positrons (scientists think all matter particles have antimatter counterparts with equal mass but opposite charge).
When these particles collide, they explode into energy that converts into new particles. Science Fiction or Fact: Will Teleporters Ever Beam Us Up? In this weekly series, Life's Little Mysteries rates the plausibility of popular science fiction concepts.
Want to get from here to there in an instant, even if "there" is miles and miles away? If some science fiction tales have it right, all you'll have to do is flip a switch and presto, you will teleport to your destination. Perhaps the most famous example of teleportation technology is the transporter on the TV show "Star Trek. " The original series' creators devised this shimmery special effect because they didn't have the budget to show a spaceship landing on various planets.
Icy Antarctica Once Ringed With Carpet of Lush Flora. The few plants that live in Antarctica today are hardy hangers-on, growing just a few weeks out of the year and surviving poor soil, lack of rain and very little sunlight.
But long ago, some parts of Antarctica were almost lush. New research finds that between about 15 million and 20 million years ago, plant life thrived on the coasts of the southernmost continent. Ancient pollen samples suggest that the landscape was a bit like today's Chilean Andes: grassy tundra dotted with small trees. This vegetated period peaked during the middle Miocene, when atmospheric carbon dioxide levels were around 400 to 600 parts per million. (Today, driven by fossil fuel use, atmospheric carbon dioxide has climbed to 393 parts per million.)
As a result, global temperatures warmed. NASA's Juno Mission to Probe Jupiter's Biggest Secrets. ANCHORAGE, Alaska — A NASA probe that is traveling through space on its way to Jupiter is expected to help astronomers unlock mysteries about the largest planet in our solar system when it arrives there in 2016.
NASA's Juno mission was launched in August 2011 to study how Jupiter formed and evolved. After a five-year journey, the spacecraft is expected to arrive at the gas giant planet in August 2016.

Interstellar Gas Molecule Mystery Revealed. Scientists have untangled the structure of an elusive space molecule that may help astronomers better understand the vast clouds of interstellar gas across our Milky Way galaxy. Unable to directly detect the coldest clouds of the most plentiful molecule in the universe, astronomers must rely on its interactions to find it. The search should become easier with an improved understanding of the compound H2-CO, frequently used as a tracer chemical. After obtaining a very accurate reading of the most plentiful variety of this compound, an international team of scientists was able to map its distribution across space.
