For decades geoscientists have been trying to detect the influence of climate on the formation of rivers, but up to now there has been no systematic evidence.
A new study, led by scientists from the University of Bristol and published today in the journal Nature, discovers a clear climatic signature on rivers globally that challenges existing theories.
New Haven, Conn. - A key question for climate scientists in recent years has been whether the Atlantic Ocean's main circulation system is slowing down, a development that could have dramatic consequences for Europe and other parts of the Atlantic rim. But a new study suggests help may be on the way from an unexpected source -- the Indian Ocean.
Think of it as ocean-to-ocean altruism in the age of climate change.
Swedish and Chinese scientists have developed organic solar cells optimised to convert ambient indoor light to electricity. The power they produce is low, but is probably enough to feed the millions of products that the internet of things will bring online.
In line with the fight against climate change and the search for a sustainable future, the idea appears of a future society based on hydrogen used as a fuel. This biofuel of the future could be what cars and engines run on (they actually already do), but without pollution and the issue of batteries, since it is much easier to store than electrical energy.
In a recent study, an international team of researchers analyzed fish bones excavated from the Early Neolithic Jiahu site in Henan Province, China. By comparing the body-length distributions and species-composition ratios of the bones with findings from East Asian sites with present aquaculture, the researchers provide evidence of managed carp aquaculture at Jiahu dating back to 6200-5700 BC.
BROOKLYN, New York, Monday, September 16, 2019 - Invasive species control is notoriously challenging, especially in lakes and rivers where native fish and other wildlife have limited options for escape.
Later during this century, around 2060, a paradigm shift in global energy consumption is expected: we will spend more energy for cooling than for heating. Meanwhile, the increasing penetration of cooling applications into our daily lives causes a rapidly growing ecological footprint. New refrigeration processes such as magnetic cooling could limit the resulting impact on the climate and the environment. Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and the Technische Universität Darmstadt have taken a closer look at today's most promising materials.
WASHINGTON--Valley fever is endemic to hot and dry regions like the southwestern United States and California's San Joaquin Valley, but a new study predicts climate change will cause the fungal infection's range to more than double in size this century, reaching previously unaffected areas across the western U.S.
Irvine, Calif., Sept. 16, 2019 - Valley fever is endemic to hot and dry regions such as the southwestern United States and California's San Joaquin Valley, but scientists at the University of California, Irvine predict that climate change will cause the fungal infection's range to more than double in size this century, reaching previously unaffected areas across the western U.S.
A source of embarrassment to some, or pure comedy to others, flatulence and the gases of the intestines are increasingly seen as playing an important role in our digestive health.
A paper led by UNSW Sydney and published in Nature Reviews Gastroenterology & Hepatology has examined all available literature on gastrointestinal gases, their interactions with the microbiome of the gut, their associated disorders and the way that they can be measured and analysed.
Communities across the United States are working with scientists to respond to climate change impacts, shows a new report and multimedia resources developed by the American Association for the Advancement of Science (AAAS). How We Respond shares details and perspectives from 18 communities using scientific information to adapt to climate change impacts and/or reduce greenhouse gas emissions.
HANOVER, N.H. - September 16, 2019 - A team from Dartmouth College and MIT has designed and conducted the first lab test to successfully detect and characterize a class of complex, "non-Gaussian" noise processes that are routinely encountered in superconducting quantum computing systems.
The characterization of non-Gaussian noise in superconducting quantum bits is a critical step toward making these systems more precise.
The fate of the world's coral reefs could depend on how well the sea creatures equip their offspring to cope with global warming.
About half the world's coral has been lost due to warming seas that make their world hostile. Instead of vivid and floral, coral bleach pale as temperatures rise. This happens because the peculiar animal cohabitates with algae, which expel under stress. When that happens, coral lose their color and a life partner that sustains them, so they starve.
When it comes to the impact of climate change on ecosystems, we still have large knowledge gaps. Most experiments are unrealistic because they do not correspond to projected climate scenarios for a specific region. As a result, we lack reliable data on what ecosystems might look like in the future, as a team of biodiversity researchers from Central Germany show in the journal "Global Change Biology". The team reviewed all experimental studies on the topic. The researchers are now calling for the introduction of common protocols for future experiments.
Achieving strength and extensibility at the same time has so far been a great challenge in material engineering: increasing strength has meant losing extensibility and vice versa. Now Aalto University and VTT Technical Research Centre of Finland researchers have succeeded in overcoming this challenge, inspired by nature.
