Great Lakes water quality is focus of new $5 million grant

Great Lakes water quality is focus of new $5 million grant

ANN ARBOR, Mich.---How could climate change and our response to it affect the Great Lakes' water quality? That's the primary question a team of 27 researchers from across the University of Michigan and collaborators at other institutions will answer with a new $5-million grant from the National Science Foundation.

Report: Tsunami detection improves, but coastal areas still vulnerable

WASHINGTON — The nation's ability to detect and forecast tsunamis has improved since the 2004 Indian Ocean tsunami, but current efforts are still not sufficient to meet challenges posed by tsunamis generated near land that leave little time for warning, says a new congressionally requested report from the National Research Council. The report calls for a comprehensive national assessment of tsunami risk and improved communication and coordination among the two federal Tsunami Warning Centers, emergency managers, media, and the public.

Avoiding dangerous climate change: An international perspective

The world will need to make substantial reductions in greenhouse gas emissions below current levels over the next few decades if the worst impacts of dangerous climate change are to be avoided. This was a key conclusion from UK and US climate scientists at an international workshop on the UK AVOID program in Washington, DC exploring the most policy-relevant aspects of understanding dangerous climate change.

Pristine rainforests are 'biogeochemical reactors'

A multinational team that includes a North Carolina State University researcher has found another piece of the atmospheric puzzle surrounding the effects of aerosol particles on climate change. Their findings will contribute to our ability to more accurately measure human impact on climate, and to determine how much pollution may "mask" the actual rate of climate change.

Putting a spin on light and atoms

Putting a spin on light and atoms

Magnetometers come in many shapes and sizes – an ordinary hand-held compass is the simplest – but alkali-vapor magnetometers are extrasensitive devices that measure magnetic fields using light and atoms. They can detect archaeological remains and mineral deposits underground by their faint magnetic signatures, among a host of other scientific applications.

'Archeologists of the air' isolate pristine aerosol particles in the Amazon

'Archeologists of the air' isolate pristine aerosol particles in the Amazon

Cambridge, Mass. and Manaus, Brazil – September 16, 2010 – Environmental engineers who might better be called "archeologists of the air" have, for the first time, isolated aerosol particles in near pristine pre-industrial conditions.

Understanding behavioral patterns: Why bird flocks move in unison

Animal flocks, be it honeybees, fish, ants or birds, often move in surprising synchronicity and seemingly make unanimous decisions at a moment's notice, a phenomenon which has remained puzzling to many researchers.

New research published today, Wednesday 15 September, in New Journal of Physics (co-owned by the Institute of Physics and German Physical Society), uses a particle model to explain the collective decision making process of flocks of birds landing on foraging flights.

Women more likely than men to accept global warming

Women more likely than men to accept global warming

EAST LANSING, Mich. — Women accept the scientific consensus on global warming more than men, according to a study by a Michigan State University researcher, who published the results in the journal Population and Environment and says it challenges common perceptions that men are more scientifically literate, said sociologist Aaron M. McCright.

New current meter provides answers for lobster industry, oyster farmers, scientists

NARRAGANSETT, R.I. – September 14, 2010 – When a federal fisheries scientist sought to learn how ocean currents affect the catch rate of lobsters, he turned to a University of Rhode Island oceanographer who had developed an innovative and inexpensive meter for measuring currents near the bottom of bays, rivers and other shallow waters.

Why 'scientific consensus' fails to persuade

Suppose a close friend who is trying to figure out the facts about climate change asks whether you think a scientist who has written a book on the topic is a knowledgeable and trustworthy expert. You see from the dust jacket that the author received a Ph.D. in a pertinent field from a major university, is on the faculty at another one, and is a member of the National Academy of Sciences. Would you advise your friend that the scientist seems like an "expert"?

Research will help ID bodies left behind by Chilean earthquake, Pinochet regime

Research will help ID bodies left behind by Chilean earthquake, Pinochet regime

New research from North Carolina State University will help medical examiners and others identify human remains of those killed during the recent earthquake in Chile, as well as the bodies of the "disappeared" who were killed during the Pinochet administration.

Lead-free piezoelectric materials of the future

Washington, D.C. (September 14, 2010) -- Piezoelectric materials have fantastic properties: squeeze them and they generate an electrical field. And vice-versa, they contract or expand when jolted with an electrical pulse. With a name derived from the Greek word meaning to squeeze or press, the piezoelectric effect was just a curiosity after it was discovered in several crystals in 1880. But in 1917, a quartz piezoelectric crystal was at the heart of the world's first submarine-detecting sonar.

Improving crisis prediction, disaster control and damage reduction

Washington, D.C. (September 14, 2010) -- Some disasters and crises are related to each other by more than just the common negative social value we assign to them. For example, earthquakes, homicide surges, magnetic storms, and the U.S. economic recession are all kindred of a sort, according to a theoretical framework presented in the journal CHAOS, which is published by the American Institute of Physics.

How do your crystals grow?

Washington, D.C. (September 14, 2010) -- Because one of the main bottlenecks in determining the structure of protein molecules is producing good isolated single crystals, improved crystallization techniques would be useful in a wide range of genomics and pharmaceutical research.
