Japan readies first robot to probe melted Fukushima reactor
(AP)—A snake-like robot designed to examine the inside of one of three melted reactors at the Fukushima Dai-ichi nuclear plant is ready to begin its expedition.
A natural radioactive tool for urban pollution studies
The amount of air pollution that city residents are exposed to depends mainly on three things: (1) how much pollution is emitted, (2) how fast it reacts or gets removed from the air, and (3) how high into ...
Satellite science improves storm surge forecasting around the world
A new online resource which will help coastguards, meteorological organisations and scientific communities predict future storm surge patterns has been created, with scientists from the National Oceanography ...
Seafloor volcano pulses may alter climate
Vast ranges of volcanoes hidden under the oceans are presumed by scientists to be the gentle giants of the planet, oozing lava at slow, steady rates along mid-ocean ridges. But a new study shows that they ...
The power of light-matter coupling
A theoretical study shows that strong ties between light and organic matter at the nanoscale open the door to modifying these coupled systems' optical, electronic or chemical properties.
Probing electron behaviour at the tips of nanocones
One of the ways of improving electrons manipulation is though better control over one of their inner characteristics, called spin. This approach is the object of an entire field of study, known as spintronics. Now, Richard ...
Randomness of megathrust earthquakes implied by rapid stress recovery after the Japan earthquake
Associate Professor Bogdan Enescu, Faculty of Life and Environmental Sciences, University of Tsukuba, collaborated with colleagues at the Swiss Federal Institute of Technology in Zurich (ETH Zurich), to show ...
Evidence from warm past confirms recent IPCC estimates of climate sensitivity
New evidence showing the level of atmospheric CO2 millions of years ago supports recent climate change predications from the Intergovernmental Panel on Climate Change (IPCC).
How will ocean acidification impact marine life?
Many marine organisms—such as coral, clams, mussels, sea urchins, barnacles, and certain microscopic plankton—rely on equilibrated chemical conditions and pH levels in the ocean to build their calcium-based ...
Mercury levels in Hawaiian yellowfin tuna increasing
Mercury concentrations in Hawaiian yellowfin tuna are increasing at a rate of 3.8 percent or more per year, according to a new University of Michigan-led study that suggests rising atmospheric levels of the toxin are to blame.
Study analyzes how manmade noise impacts bird decline
How noise can affect interactions between human and natural systems is the topic of a National Science Foundation grant awarded to researchers at Penn State and Boise State University.
Flooding could become a daily problem in North Carolina by 2045, report says
North Carolina's coast will see more frequent and more destructive floods at high tide over the next 30 years, several studies say - even on mild, sunny days - as rising sea levels shove the Atlantic Ocean higher onto our ...
New method allows for greater variation in band gap tunability
If you can't find the ideal material, then design a new one.
Measuring oxygen concentrations in sea water in the remote past
It is possible to measure oxygen concentrations in sea water in the remote past, a study published this month in Nature Geoscience demonstrates.
