Nature and nurture have found a new companion — historical context.
A new study has produced the best evidence yet that the role of genetics in complex traits, including obesity, varies over time. Both the era in which scientific research is conducted and the era in which subjects were born may have an impact on the degree to which genetic factors are present in scientific data. (more…)
Study results could foreshadow earth’s future climate, MU researcher says
COLUMBIA, Mo. – For years, scientists have thought that a continental ice sheet formed during the Late Cretaceous Period more than 90 million years ago when the climate was much warmer than it is today. Now, a University of Missouri researcher has found evidence suggesting that no ice sheet formed at this time. This finding could help environmentalists and scientists predict what the earth’s climate will be as carbon dioxide levels continue to rise.
“Currently, carbon dioxide levels are just above 400 parts per million (ppm), up approximately 120 ppm in the last 150 years and rising about 2 ppm each year,” said Ken MacLeod, a professor of geological sciences at MU. “In our study, we found that during the Late Cretaceous Period, when carbon dioxide levels were around 1,000 ppm, there were no continental ice sheets on earth. So, if carbon dioxide levels continue to rise, the earth will be ice-free once the climate comes into balance with the higher levels.” (more…)
PASADENA, Calif. — NASA’s Mars rover Curiosity now has a view of a patch of exposed bedrock scientists selected for a few days of close-up study, the first such study since the rover began its long trek to Mount Sharp two months ago.
Curiosity reached the crest of a rise informally called “Panorama Point.” From Panorama Point, the rover took photographs of a pale-toned outcrop area that the team chose earlier as “Waypoint 1” on the basis of imagery from NASA’s Mars Reconnaissance Orbiter. (more…)
Environmental conditions have a much stronger influence on the mix of microbes living in various parts of your body than does competition between species. Instead of excluding each other, microbes that fiercely compete for similar resources are more likely to cohabit in the same individual.
This phenomenon was discovered in a recent study of the human microbiome – the vast collection of our resident bacteria, fungi, and other tiny organisms. (more…)
PASADENA, Calif. – Detailed analysis and review have borne out researchers’ initial interpretation of pebble-containing slabs that NASA’s Mars rover Curiosity investigated last year: They are part of an ancient streambed.
The rocks are the first ever found on Mars that contain streambed gravels. The sizes and shapes of the gravels embedded in these conglomerate rocks — from the size of sand particles to the size of golf balls — enabled researchers to calculate the depth and speed of the water that once flowed at this location.

Microsoft: Working with automotive industry to design an updateable car that’s easier to use and responds to the driver’s needs.
Microsoft’s Pranish Kumar and his team work to develop reliable in-car experiences, not by sitting at a desk but by working behind the wheel of a fleet of test vehicles. (more…)
The behaviour of seabirds during migration – including patterns of foraging, rest and flight – has been revealed in new detail using novel computational analyses and tracking technologies.
Using a new method called ‘ethoinformatics’, described as the application of computational methods in the investigation of animal behaviour, scientists have been able to analyse three years of migration data gathered from miniature tracking devices attached to the small seabird the Manx Shearwater (Puffinus puffinus).

South Korea’s most powerful data storage system helps tackle weather’s data deluge
Seoul, SOUTH KOREA – 27 Feb 2013: South Korea’s Meteorological Administration (KMA) and IBM today announced a project to help KMA and its affiliate, the National Meteorological Satellite Center (NMSC), tackle Big Data for better, more accurate and predictive environmental forecasting.
As South Korea’s national meteorological organization, KMA’s mission is to protect citizens’ lives and property from natural disasters and support economic activities sensitive to environmental conditions. (more…)
