Last month the extent of sea ice covering the Arctic Ocean declined to the second-lowest extent on record. Satellite data from NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado in Boulder showed that the summertime sea ice cover narrowly avoided a new record low.
The time it takes for new products to come to market is getting ever shorter. As a consequence, goods are being produced using manufacturing facilities and IT systems that were designed with completely different models in mind. Fraunhofer developers want to make factories smarter so they can react to changes of their own accord.
A NASA-led study has documented an unprecedented depletion of Earth's protective ozone layer above the Arctic last winter and spring caused by an unusually prolonged period of extremely low temperatures in the stratosphere.
Forest Service Southern Research Station (SRS) scientists recently used long-term data from the Coweeta Hydrological Laboratory (Coweeta) in Western North Carolina to examine the feasibility of managing forests for water supply under the changing weather conditions forecast for the future.
The ability of forests, plants and soil to suck carbon dioxide (CO2) from the air has been under-estimated, according to a study on Wednesday that challenges a benchmark for calculating the greenhouse-gas problem.
The Obama administration cut corners before concluding that climate-change pollution can endanger human health, a key finding underpinning costly new regulations, an internal government watchdog said Wednesday.
Metazoan-dominated reefs only took 1.5 million years to recover after the largest species extinction 252 million years ago, an international research team including paleontologists from the University of Zurich has established based on fossils from the Southwestern USA.
Changing human activities coupled with a dynamic environment over the past few centuries have caused fluctuating periods of decline and recovery of corals reefs in the Hawaiian Islands, according to a study sponsored in part by the Institute for Ocean Conservation Science at Stony Brook University. Using the reefs and island societies as a model social-ecological system, a team of scientists reconstructed 700 years of human-environment interactions in two different regions of the Hawaiian archipelago to identify the key factors that contributed to degradation or recovery of coral reefs.
Much of what we write about here at GeekMom is high tech gadgetry, so when I say 'solar' you might think of any number of modern solar powered electrical systems. What you probably didn't think about is the super low tech but incredibly brilliant solar bottle bulb developed by students from the Massachusetts Institute of Technology (MIT).
Deforestation in the rainforests of West Africa reduces rainfall over the rest of the forest, according to new University of Leeds research published in Geophysical Research Letters.
Auburn University researchers said oil mats submerged in the seabed more than a year after the biggest oil spill in U.S. history pose long-term threats to coastal ecosystems across the northern Gulf of Mexico.
The study, released on Tuesday by the school's engineering department, showed that tarballs churned to the surface by Tropical Storm Lee and deposited along Alabama beaches this month had "essentially identical" chemical composition as samples taken from mats after the Deepwater Horizon oil spill.
"Our interpretation of these observations is that submerged tar mats buried offshore of this coastline are breaking apart to yield these tar balls," the study reads, estimating the tarballs in question contained about 17 percent oil by mass.
Megacities offer the enticing prospect of employment and the benefits of an urban infrastructure - but they also expose their inhabitants to high levels of air pollution. Together with an Indian Partner Group of the Max Planck Institute for Chemistry in Mainz, Bhola Ram Gurjar is analyzing this pollution and how badly it is affecting the health of city dwellers.
The website titled "Visualizing Our Future Selves"[news21.com] attempts to answer the question how the dramatically aging demographics in the US will change over the next 40 years.
It is an example of a 'personalized' visualization of sorts, in that users are asked to submit their personal demographic data, such as birth year, race, state, living situation and gender. The resulting diagrams then reveals country-wide statistical information in the context of one's own situation, divided into 4 different groups: Population, State, Health and Finances. Accordingly, the application shows an animated population pyramid, a population age density map of the US, a disease (e.g. cancer, heart disease, diabetes) prevalence forecast, and an income versus expenditure comparison filtered by several demographic variables.
In the next 20 years, more than 590,000 square miles of land globally - more than twice the size of Texas - will be gobbled up by cities, a trend that shows no signs of stopping and one that could pose threats on several levels, says a Texas A&M University geographer who is part of a national team studying the problem.
A recent study of the Catalina Eddy performed by Kanamitsu. The figure shows the 3-hourly evolution of the eddy during two days. Kanamitsu discovered that the eddy disappears during 00Z and 03Z, which had never been reported before. This was due to the lack of high time-resolution observations. This kind of analysis is only possible using the dynamically downscaled analysis
In an attempt to mimic the photosynthetic systems found in plants and some bacteria, scientists have taken a step toward developing an artificial light-harvesting system (LHS) that meets one of the crucial requirements for such systems: an approximately 100% energy transfer efficiency. Although high energy transfer efficiency is just one component of the development of a useful artificial LHS, the achievement could lead to clean solar-fuel technology that turns sunlight into chemical fuel.
The U.S. Department of Energy's (DOE) National Renewable Energy Laboratory (NREL) has produced and made available a rich data set showing what happens, second-by-second, when clouds pass over a solar power installation.
Examples of the damages caused by these so-called "invasive species" are seemingly as endless as the amount of battles waged against them.
But are all non-native species bad?
Biologist Mark Davis says no. Davis, a professor from Macalester College in St. Paul, Minnesota, believes it's time to raise the white flag against non-native species. Most non-native species, he said, are harmless -- or even helpful.
In a letter published in the journal Nature this past June, Davis and 18 other ecologists argued that these destructive invasive species -- or those non-native species that cause ecological or economic harm -- are only a tiny subset of non-native species, and that this tiny fraction has basically given all new arrivals a bad name.
Mount Sinai School of Medicine researchers have found that climate change may lead to more asthma-related health problems in children, and more emergency room (ER) visits in the next decade.
It has all the appearances of a breakthrough in battery technology, except that it's not a battery. Researchers at Nanotek Instruments, Inc., and its subsidiary Angstron Materials, Inc., in Dayton, Ohio, have developed a new paradigm for designing energy storage devices that is based on rapidly shuttling large numbers of lithium ions between electrodes with massive graphene surfaces. The energy storage device could prove extremely useful for electric vehicles, where it could reduce the recharge time from hours to less than a minute. Other applications could include renewable energy storage (for example, storing solar and wind energy) and smart grids.
