New technique measures mass of exoplanets
Method will help scientists determine the mass of exoplanets that are not measurable in any other way. To date, scientists have confirmed the existence of more than 900 exoplanets circulating outside our solar system. To determine if any of these far-off worlds are habitable requires knowing an exoplanet's mass - which can help tell scientists whether the planet is made of gas or rock and other life-supporting materials.

Neanderthal genome shows evidence of early human interbreeding, inbreeding
Neanderthal genome shows evidence of early human interbreeding, inbreeding
The most complete sequence to date of the Neanderthal genome, using DNA extracted from a woman's toe bone that dates back 50,000 years, reveals a long history of interbreeding among at least four different types of early humans living in Europe and Asia at that time, according to University of California, Berkeley, scientists.

Duck-billed dino’s fleshy top a historic find
UAlberta team says discovery of "mummified" dinosaur head crest offers new insight into dino appearance, behaviour. Artist's conception showing the newly discovered fleshy crest atop the head of an Edmontosaurus (Image: Julius Csotonyi) University of Alberta scientists have unearthed an exceptionally well-preserved fossil that yields new clues about the appearance and behaviour of duck-billed dinosaurs.

First Rock Dating Experiment Performed on Mars
First Rock Dating Experiment Performed on Mars
Although researchers have determined the ages of rocks from other planetary bodies, the actual experiments-like analyzing meteorites and moon rocks-have always been done on Earth. Now, for the first time, researchers have successfully determined the age of a Martian rock-with experiments performed on Mars.

Ancient fresh water lake on Mars could have sustained life
Ancient fresh water lake on Mars could have sustained life
Scientists have found evidence that there was once an ancient lake on Mars that may have been able to support life. It is exciting to think that billions of years ago, ancient microbial life may have existed in the lake's calm waters, converting a rich array of elements into energy.

New light on the functional importance of dinosaur beaks
Why beaks evolved in some theropod dinosaurs and what their function might have been is the subject of new research by an international team of palaeontologists published this week in PNAS (Proceedings of the National Academy of Sciences). Beaks are a typical hallmark of modern birds and can be found in a huge variety of forms and shapes.

Great Barrier Reef memories: First deepwater fossil study reveals reef’s past and future
26 November 2013 Many people look back at their time on the Great Barrier Reef by viewing holiday snaps. Scientists have taken an even longer look back at the Great Barrier Reef via another image caught in time - deepwater fossils - which reveal the important role the deepwater reef plays in the health of the whole reef.

Methane Emissions in California and U.S. 1.5 Times Greater Than Expected
Methane Emissions in California and U.S. 1.5 Times Greater Than Expected
Current official inventories of methane emissions, a potent greenhouse gas released from landfills, livestock ranches and oil and gas facilities, may be underestimated both nationally and in California by a factor of about 1.5, according to new research from the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and others.

Asteroids’ close encounters with Mars
Scientists find that Mars, not Earth, shakes up some near-Earth asteroids. For nearly as long as astronomers have been able to observe asteroids, a question has gone unanswered: Why do the surfaces of most asteroids appear redder than meteorites - the remnants of asteroids that have crashed to Earth?

UT Researchers Use Simple Scaling Theory to Better Predict Gas Production in Barnett Shale Wells
AUSTIN, Texas — Researchers at The University of Texas at Austin have developed a simple scaling theory to estimate gas production from hydraulically fractured wells in the Barnett Shale. The method is intended to help the energy industry accurately identify lowand high-producing horizontal wells, as well as accurately predict how long it will take for gas reserves to deplete in the wells.

Amber Provides New Insights Into the Earth's Atmosphere
Amber Provides New Insights Into the Earth’s Atmosphere
An international team of researchers led by Ralf Tappert, University of Innsbruck, reconstructed the composition of the Earth's atmosphere of the last 220 million years by analyzing modern and fossil plant resins. The results suggest that atmospheric oxygen was considerably lower in the Earth's geological past than previously assumed.

Buried leaves reveal precolonial eastern forests and guide stream restoration
Red Oak (left), American Beech (center), Sweet Birch (right). These are fossil leaves removed from the Denlinger Mill study site. UNIVERSITY PARK, Pa. Sediment behind milldams in Pennsylvania preserved leaves deposited just before European that provide a glimpse of the ancient forests, according to a team of geoscientists, who note that neither the forests nor the streams were what they are today.

'Tiger stripes' underneath Antarctic glaciers slow the flow Posted November 7, 2013; 04:15 p.m. by Catherine Zandonella, Office of the Dean for Research Narrow stripes of dirt and rock beneath massive Antarctic glaciers create friction zones that slow the flow of ice toward the sea, researchers at Princeton University and the British Antarctic Survey have found.

Gas Injection Probably Triggered Small Earthquakes Near Snyder, Texas
Gas Injection Probably Triggered Small Earthquakes Near Snyder, Texas
AUSTIN, Texas - A new study correlates a series of small earthquakes near Snyder, Texas between 2006 and 2011 with the underground injection of large volumes of gas, primarily carbon dioxide (CO2) - a finding that is relevant to the process of capturing and storing CO2 underground.

Pinpointing the timing of sudden climate change
Pinpointing the timing of sudden climate change
A team of scientists has shown that during a 1000-year cold period at the end of the Ice Age, known as the Younger Dryas, the climate started to recover in Germany 120 years before Norway. The researchers looked at changes in the sediment of a lake in Germany and compared it to lake sediment records of a Norwegian lake.

Scientists digitally reconstruct giant steps taken by dinosaurs
Scientists digitally reconstruct giant steps taken by dinosaurs
30 Oct 2013 One of the world's largest dinosaurs has been digitally reconstructed by experts from The University of Manchester allowing it to take its first steps in over 94 million years. The Manchester team, working with scientists in Argentina, were able to laser scan a 40 metre-long skeleton of the vast Cretaceous Argentinosaurus dinosaur.

Reading ancient climate from plankton shells
Climate changes from millions of years ago are recorded at daily rate in ancient sea shells, new research shows. For slow-growing plankton it opens the way to seeing seasonal variations in ocean temperatures Simon Redfern A huge X-ray microscope has revealed growth bands in plankton shells that show how shell chemistry records the sea temperature.

Quake-triggered landslides a significant hazard in Seattle
Quake-triggered landslides a significant hazard in Seattle
The next big earthquake on the Seattle fault could trigger destructive landslides in the city, potentially affecting a much larger area than previously thought, and in areas outside those currently considered to be landslide prone, a new University of Washington-led study shows. "A major quake along the Seattle fault is among the worst-case scenarios for the area, since the fault runs just south of downtown.” said Kate Allstadt, a UW doctoral student in Earth and space sciences.

Archaeologists rediscover the lost home of the last Neanderthals
Archaeologists rediscover the lost home of the last Neanderthals
A record of Neanderthal archaeology, thought to be long lost, has been re-discovered by UCL scientists working in the Channel island of Jersey. The study, published in the Journal of Quaternary Science, reveals that a key archaeological site has preserved geological deposits which were thought to have been lost through excavation 100 years ago.
