Approximately 30 percent of CO2 emitted to the atmosphere by human activities, mainly the use of fossil fuels and deforestation, is taken up by terrestrial ecosystems such as forests and grasslands. The recent reports from the IPCC concluded that new land-use options to enhance this terrestrial carbon sink are needed to meet the goals of the Paris Agreement on Climate.
Following the accident at the Fukushima nuclear power plant in March 2011, the Japanese authorities decided to carry out major decontamination works in the affected area, which covers more than 9,000 km2.
(Boston)--Cigarette smoking changes the types of cells that are present in the respiratory track and some biological processes necessary for detoxification of cigarette smoke are restricted to specific types of cells.
Scientists from Australia and the US have discovered and identified the genetic cause of a previously unknown human autoinflammatory disease.
The researchers determined that the autoinflammatory disease, which they termed CRIA (cleavage-resistant RIPK1-induced autoinflammatory) syndrome, is caused by a mutation in a critical cell death component called RIPK1.
Generally speaking, "flue gas" refers to any gas coming out of a pipe, exhaust, chimney etc as a product of combustion in a fireplace, oven, furnace, boiler, or steam generator. But the term is more commonly used to describe the exhaust vapors exiting the flues of factories and powerplants. Iconic though they may be, these flue gases contain significant amounts of carbon dioxide (CO2), which is a major greenhouse gas contributing to global warming.
An analysis of sediment carried by glaciers in both South America and East Africa indicates that tropical glaciers not just in South America but across the tropics began to melt earlier than expected at the end of the Last Glacial Maximum (26,000-19,000 years ago), before atmospheric carbon dioxide levels began to rise. The study's authors suggest that the early melting may have been triggered by rising temperatures at the North and South Poles, which reduced a heat-driven atmospheric circulation cycle that in turn slowed the movement of heat out of the tropics.
CORVALLIS, Ore. - An international team co-led by an Oregon State University chemistry researcher has uncovered a better way to scrub carbon dioxide from smokestack emissions, which could be a key to mitigating global climate change.
Published today in Nature, the findings are important because atmospheric CO2 has increased 40 percent since the dawn of the industrial age, contributing heavily to a warming planet.
Stanford University School of Medicine investigators have succeeded in distinguishing the molecular pathway responsible for an illicit drug's abuse potential from the one behind its propensity to make people feel sociable.
The discovery, described in a study to be published Dec. 11 in Science Translational Medicine, could lead to novel treatments for psychiatric disorders marked by social awkwardness and withdrawal.
The findings were made in mouse experiments.
Police officers face well-documented risks, with more than 50,000 a year assaulted on the job in the United States.
But new research has found that the use of information technology by law enforcement agencies can significantly cut the number of police killed or injured in the line of duty, reducing violence as much as 50%.
A new study based on Veterans Affairs health records finds that non-drug therapies given to military service members with chronic pain may reduce the risk of long-term adverse outcomes, such as alcohol and drug disorder and self-induced injuries, including suicide attempts.
The findings appeared online Oct. 28, 2019, in the Journal of General Internal Medicine.
ANN ARBOR--What could Azteca ants in coffee farms in Mexico have in common with leopards' spots and zebras' stripes?
After two decades of analyzing the rise, spread and collapse of Azteca ant colonies in a coffee farm in Mexico, University of Michigan researchers have proven that the ant distributions follow a pattern named after chemist Alan Turing, who first described it in 1952, that is said to explain leopards' spots and other patterns in nature.
You're on a diet, but the aroma of popcorn in the movie theater lobby triggers a seemingly irresistible craving.
Within seconds, you've ordered a tub of the stuff and have eaten several handfuls.
Impulsivity, or responding without thinking about the consequences of an action, has been linked to excessive food intake, binge eating, weight gain and obesity, along with several psychiatric disorders including drug addiction and excessive gambling.
Researchers in Korea have found an effective and inexpensive strategy to transform solar cells from opaque to transparent. Existing transparent solar cells tend to have a reddish hue and lower efficiency, but by punching holes that are around 100 μm in diameter (comparable in size to a human hair) on crystalline silicon wafers, it allows light through without coloring. The holes are then strategically spaced, so the human eye is unable to "see" the pattern. The work appears December 11 in the journal Joule.
Underground fiber-optic cables, like those that connect the world through phone and internet service, hold untapped potential for monitoring severe weather, according to scientists at Penn State.
Researchers turned miles of cables under the University Park campus into thousands of virtual sensors capable of detecting tiny seismic events caused by thunder echoing down from the sky during a storm in April.
Scientists evaluated mouse models used for developing new treatments for mood disorders associated with Huntington's disease and recommend which are most relevant and have greater potential for success. They report their results in the Journal of Huntington's Disease.
