LHC experiments bring new insight into matter of the primordial universe
Experiments using heavy ions at CERN's Large Hadron Collider (LHC) are advancing understanding of the primordial universe. The ALICE, ATLAS and CMS collaborations have made new measurements of the kind of matter that probably existed in the first instants of the universe. They will present their latest results at the Quark Matter 2012 conference, which starts today in Washington DC. The new findings are based mainly on the four-week LHC run with lead ions in 2011, during which the experiments collected 20 times more data than in 2010.

Meddling With Male Malaria Mosquito 'Mating Plug' to Control an Epidemic
Using information about the unique mating practices of the male malaria mosquito - which, unlike any other insect, inserts a plug to seal its sperm inside the female - scientists are zeroing in on a birth-control drug for Anopheles mosquitoes, deadly carriers of the disease that threatens 3 billion people, has infected more than 215 million and kills 655,000 annually.
They reported on August 19 at the 244th National Meeting & Exposition of the American Chemical Society in Philadelphia on development of an approach for screening substances that could prevent formation of the plug, thus preventing mosquitoes from reproducing and spreading malaria.

Dog stumbles upon 300 million-year-old fossil
A family and their dog named Kitty have stumbled upon one of the most significant fossil finds ever in Nova Scotia.
The reptile fossil, affectionately nicknamed "Superstar," is the first of its kind to be found in the province. While out walking along Nova Scotia's fossil-rich Northumberland shore, Patrick Keating, his family, and their dog, Kitty, found a fossilized rib cage, backbone and partial sail. When they went back to the same area a week later, they found the creature's fossilized skul. |  |
How Domed Dinosaurs Grew Up
The history of pachycephalosaurs is mostly a story of domes. Even though some skeletons have been uncovered over the years, the most commonly-found part of these bipedal Cretaceous herbivores is the thickened, decorated skull. As a result, much of what we know about these dinosaurs comes from skull fragments, and this can sometimes seed confusion about which fossils represent new species and which are individuals of already-known dinosaurs.
Neanderthal and Human Matings Get a Date
Two years ago the analysis of the Neanderthal genome revealed modern humans carry Neanderthal DNA, implying our ancestors mated with Neanderthals at some point in the past. Scientists only found genetic traces of Neanderthals in non-African people, leading to the conclusion that Neanderthal-human matings must have occurred as modern humans left Africa and populated the rest of the world. A new paper (PDF) posted on arXiv.org puts a date on those matings: 47,000 to 65,000 years ago—a time that does indeed correspond with human migrations out of Africa.
Skull pushes back clock on early human migration
CHICAGO — An ancient skull discovered in a cave in Laos has pushed back the clock on human migration to Southeast Asia by as much as 20,000 years, a study has found.
The skull discovered in the Annamite Mountains in northern Laos is the oldest modern human fossil found in Southeast Asia and is believed to be between 46,000 and 63,000 years old. The find also reveals that early humans did not simply follow the Asian coast as they migrated from Africa to Australia, as some researchers have argued, but that some also moved inland into unfamiliar terrain. |  |
NASA wants to measure 'Marsquakes'
WASHINGTON: Just 10 days after NASA's Curiosity rover sent back its first color photos of the Martian landscape, the US space agency said on Monday it wants in 2016 to take a better look at what's happening beneath the Red Planet's surface.
"Does Mars have fault lines like the Earth does? How extensive are those? What kinds of 'marsquakes' are there?"
These, NASA official Lindley Johnson told reporters on a conference call, are some of the important questions the project hopes to answer.

Earthlings Look for Signs in New Photos of Mars
For more than two weeks, retired sculptor George J. Haas has been glued to his computer, watching as NASA's "Curiosity" rover returns its first photographs from the surface of Mars.
Mr. Haas and a small group of dedicated colleagues have pored over other images from the red planet for decades, looking for features that could have been created by intelligent beings. Over the years, among other things, they have seen a face they describe as half-human, half-feline. And a parrot-shaped feature on a mound of rock with "17 points of anatomical correctness.". |  |
