Curvy mountain belts

Updated: 2012-06-29 21:30:03

Boulder, Colorado, USA – Mountain belts on Earth are most commonly formed by collision of one or more tectonic plates. The process of collision, uplift, and subsequent erosion of long mountain belts often produces profound global effects, including changes in regional and global climates, as well as the formation of important economic resources, including oil and gas reservoirs and ore deposits. Understanding the formation of mountain belts is thus a very important element of earth science research. read more

Caffeine boosts power for elderly muscles

Updated: 2012-06-29 02:30:18

A new study to be presented at the Society for Experimental Biology meeting on 30th June has shown that caffeine boosts power in older muscles, suggesting the stimulant could aid elderly people to maintain their strength, reducing the incidence of falls and injuries. For adults in their prime, caffeine helps muscles to produce more force. But as we age, our muscles naturally change and become weaker. read more

Saving the Baltic Sea

Updated: 2012-06-28 15:00:58

Over the last decade, an average of 60,000 km2 of the Baltic Sea bottom has suffered from hypoxia without enough oxygen to support its normal ecosystem. Several large-scale geo-engineering interventions are currently on the table as proposed solutions to this problem. Researchers from Lund University are calling for geo-engineering efforts that mix oxygen into the Deep Baltic to be abandoned. read more

Space tornadoes power the atmosphere of the Sun

Minneapolis, MN—27 June, 2012—What do Avatar, The Chronicles of Narnia, X-Men, Harry Potter, and Pirates of the Caribbean have in common? Simulated physics. That's right. Making visual effects real for movie audiences—be it Avatar's vast ocean surface or rising water levels in The Deathly Hallows—requires quite a bit of physics and math. Physical equations and scientific computations are generated behind the scenes to ensure that the elements you see on the big screen obey the same laws of physics as their real counterparts.read more

Greenland ice may exaggerate magnitude of 13,000-year-old deep freeze

Updated: 2012-06-25 22:00:15

MADISON -- Ice samples pulled from nearly a mile below the surface of Greenland glaciers have long served as a historical thermometer, adding temperature data to studies of the local conditions up to the Northern Hemisphere's climate. But the method -- comparing the ratio of oxygen isotopes buried as snow fell over millennia -- may not be such a straightforward indicator of air temperature.read more

Significant sea-level rise in a 2-degree warming world

Updated: 2012-06-24 19:00:08

The study is the first to give a comprehensive projection for this long perspective, based on observed sea-level rise over the past millennium, as well as on scenarios for future greenhouse-gas emissions. "Sea-level rise is a hard to quantify, yet critical risk of climate change," says Michiel Schaeffer of Climate Analytics and Wageningen University, lead author of the study. "Due to the long time it takes for the world's ice and water masses to react to global warming, our emissions today determine sea levels for centuries to come."read more
