Other Worlds, Other Tectonics, Other Life

Planets are warmed by their sun. Planets also has their own internal warmth that drives local volcanism and tectonics and helps keep water liquid and not frozen. Scattered around the Milky Way are stars that resemble our own sun—but a new study is finding that any planets orbiting those stars may very well be hotter and more dynamic than Earth and not due to their suns. That’s because the interiors of any terrestrial planets in these systems are likely warmer due to their radioactive composition than Earth—up to 25 percent warmer, which would make them more geologically active and more likely to retain enough liquid water to support life.

NOAA predicts sea level will rise 0.2 to 2 meters by 2100

The worst potential scenario for sea level rise around the US coastline this century is more than two meters, says an authoritative report issued today by NOAA's Climate Program Office. Regardless of how much warming occurs over the next 100 years, sea level rise is not expected to stop in 2100. More than 8 million people in the US live in areas at risk of coastal flooding. Along the Atlantic Coast alone, almost 60 percent of the land that is within a meter of sea level is planned for further development, with inadequate information on the potential rates and amount of sea level rise.

Accurate flood forecasting gets closer

Heavy rainfall and the problems of flooding in towns have never been far from peoples' minds or the news headlines over the past few weeks. Now scientists say that new research will help to accurately pinpoint which individual streets are most at risk from flooding during severe rainstorms.

Milling Chemicals with no Solvents

Traditionally new chemicals are made within a solvent solution. This aids in the active chemicals reaching one another. Solvents are flammable and often pose other hazards, For the first time, scientists have studied a milling reaction in real time, using highly penetrating X-rays to observe the surprisingly rapid transformations as the mill mixed, ground, and transformed simple ingredients into a complex product. This research, reported Dec. 2 in Nature Chemistry, promises to advance scientists' understanding of processes central to the pharmaceutical, metallurgical, cement and mineral industries – and could open new opportunities in green chemistry and environmentally friendly chemical synthesis.

Magnetic Fields from Antarctic research stations a potential problem

Antarctic research stations could be adversely affecting the local environment by emitting magnetic pollution, a new study has found. A new aerial survey is the first to research and assess the possible impact of a research station in Antarctica on magnetic fields. Estimations indicated that the station generated a magnetic field that extends up to 650 metres from the station with a peak strength of 2800 nanotesla (nT) within 100 metres from the station on the ground. This may have implications for organisms in Antarctica that are negatively affected by magnetic fields but the report's authors say further research is needed to investigate this.

Can’t Quit? Smoking Less Will Also Improve Your Health

Countless studies demonstrate the benefits of quitting smoking altogether, benefits which include lowered risk of disease, increased life expectancy, and an overall improvement in quality of life. But health professionals acknowledge that quitting altogether can be a long and difficult road, and only a small percentage succeed. A recent study at Tel Aviv University has shown that even reducing the quantity of cigarettes smoked daily has many health benefits.

Date Palm Leaves Could Improve Water Treatment Across the Middle East

Date palm leaves — currently a waste product of date farming — could be used to remove pharmaceutical chemicals and dyes from hospital wastewater, say researchers from Sultan Qaboos University (SQU) in Oman. The first hospital wastewater treatment pilot project is due to start in Oman early next year, and scientists are working to use this technology in both drinking water filters and for industrial wastewater treatment.

CO2 Output Hits Record High

Around the world, we are emitting more carbon dioxide than ever. For 2012, according to new projections by the Global Carbon Project, there is likely to be a 2.6 percent rise in global CO2 emissions from the burning of fossil fuels compared to the year before. That puts emissions of the gas at 58 percent higher than 1990 levels.

Planning for Climate Change

The Metcalf Institute at the University of Rhode Island recently held the second in series of seminars on climate change. Here are a few noteworthy points that were offered Nov. 30 by 15 scientists, engineers, planners and other experts: Snowpack in the Northeast has decreased its annual volume by 11 percent since 1900. Sea level is projected to rise between 2.5 and 6 feet by 2100. "If you want to see what 5 feet of sea level rise will look like, you look at Hurricane Sandy," said Bryan Oakley, a URI researcher and professor of earth sciences at Eastern Connecticut State University.
