Eight of the top 10 U.S. cities that have seen an increase in so-called "nuisance flooding"- which causes such public inconveniences as frequent road closures, overwhelmed storm drains and compromised infrastructure- are on the East Coast. This nuisance flooding, caused by rising sea levels, has increased on all three U.S. coasts, between 300 and 925 percent since the 1960s.
The federal government is planning to use sound blasting to conduct research on the ocean floor...
Norwegian explorer Roald Amundsen became the first man to reach the South Pole in December of...
Dinosaurs might have survived the asteroid strike that wiped them out if it had taken place slightly earlier or later in history, scientists say. A fresh study using up-to-date fossil records and improved analytical tools has helped palaeontologists to build a new narrative of the prehistoric creatures' demise, some 66 million years ago.
In the first broad-scale estimate of air pollution removal by trees nationwide, U.S. Forest Service scientists and collaborators calculated that trees are saving more than 850 human lives a year and preventing 670,000 incidences of acute respiratory symptoms.
Climate models can recreate the slowdown in global warming since 1998, as long as they correctly factor in crucial variables such as the state of the El Niño system. The discovery vindicates the models against the accusation that they failed to predict the “alleged hiatus” in surface warming.
Scientists have long been concerned that global warming may push Earth’s climate system across a “tipping point,” where rapid melting of ice and further warming may become irreversible – a hotly debated scenario with an unclear picture of what this point of no return may look like. A newly published study probed the geologic past to understand mechanisms of abrupt climate change.
A new study finds more than 75 percent of the water loss in the drought-stricken Colorado River Basin since late 2004 came from underground resources. The extent of groundwater loss may pose a greater threat to the water supply of the western United States than previously thought.
The U.S. Food and Drug Administration isn't required to hold public hearings to evaluate the health risks of widespread use of antibiotics in animal feed, a federal appeals court ruled Thursday. The decision by the 2nd U.S. Circuit Court of Appeals reversed a ruling in 2012 by a district court that sided with several health and consumer organizations that sued the FDA after the agency decided against holding the hearings.
Surprisingly, cloud cover increases when more dust blows off the west coast of Africa. Researchers calculated more clouds as more dust flowed from Africa over the Atlantic Ocean.
Imagine a smog-free Los Angeles, where electric cars ply silent freeways, solar panels blanket rooftops and power plants run on heat from beneath the earth, from howling winds and from the blazing desert sun. A new study finds that it is technically and economically feasible to convert California’s all-purpose energy infrastructure to one powered by clean, renewable energy.
Small-scale advances in fluid physics, materials engineering and nanoscience have brought scientists one step closer to mimicing the way a desert beetle collects and drinks water. Understanding how liquids interact with different materials can lead to more efficient, inexpensive processes and products, and might even lead to airplane wings impervious to ice and self-cleaning windows.
An interdisciplinary team of researchers examined how wildlife decline can result in loss of food and employment, which in turn engenders increased crime and fosters political instability.
The planet's current biodiversity is the highest in the history of life. But it may be reaching a tipping point. In a new review of scientific literature and analysis of data, an international team of scientists cautions that the loss and decline of animals is contributing to what appears to be the early days of the planet's sixth mass biological extinction event.
Repeated freezing and thawing might not be good for the average steak, but each fall it might help wood frogs prepare to survive Alaska’s winter cold. Frogs prevent the freeze-pop effect by packing their cells with glucose, a kind of sugar that reduces drying and stabilizes cells, a process scientists call cryoprotection.
Strengthening community forest rights is an essential strategy to reduce billions of tons of carbon emissions, making it an effective way for governments to meet climate goals, safeguard forests and protect the livelihoods of their citizens, according to a major new report.
New research shows that urban “heat islands” are slowly killing red maples in the southeastern United States. One factor is that researchers have found warmer temperatures increase the number of young produced by the gloomy scale insect – a significant tree pest – by 300 percent, which in turn leads to 200 times more adult gloomy scales on urban trees.
According to the World Health Organization, 3.4 million people die from water-related diseases every year. A research team spent a year researching a membrane filter and developing a prototype. What makes the DrinkPure filter unique is that you can screw it on to virtually any plastic bottle. It doesn't require a pump or a reservoir.
A 2 C increase in temperature around the world by 2050, according to one of the scenarios predicted by the Intergovernmental Panel on Climate Change, may be advantageous to the physiology and the biochemical and biophysical processes involved in the growth of forage plants such as Stylosanthes capitata Vogel, a legume used for livestock grazing in tropical countries like Brazil.
The popular culinary herbs oregano and rosemary are packed with healthful compounds, and now lab tests show they could work in much the same way as prescription anti-diabetic medication. Scientists found that how the herbs are grown makes a difference, and they also identified which compounds contribute the most to this promising trait.
Scientists attached radio-frequency identification (RFID) tags to hundreds of individual honey bees and tracked them for several weeks. The effort yielded two discoveries: Some foraging bees are much busier than others; and if those busy bees disappear, others will take their place.
British supermarket Sainsbury's has announced plans for one of its grocery stores to come off the national grid. Industry partners Biffa and Sainsbury's have developed an innovative facility that will allow Sainsbury’s Cannock store to run on power generated solely from the supermarket’s own food waste.
Scientists are looking for ways to turn bamboo into a construction material more akin to wood composites, like plywood. The idea is that a stalk, or culm, can be sliced into smaller pieces, which can then be bonded together to form sturdy blocks—much like conventional wood composites.
Using the second fastest supercomputer in the world, a scientist at the U.S. Department of Energy’s Ames Laboratory is attempting to develop a more efficient process for purifying rare-earth materials.
The globe is on a hot streak, setting a heat record in June. That's after the world broke a record in May. The National Oceanic and Atmospheric Administration announced that last month's average global temperature was 61.2 degrees, which is 1.3 degrees higher than the 20th century average.
A new device, based on a fly's freakishly acute hearing, may find applications in futuristic hearing aids and military technology.
Federal wildlife refuges in the Northwest and Hawaii will phase out a class of pesticides that are chemically similar to nicotine because they pose a threat to bees and other pollinators key to crop growth.
Research shows ancient mammoths and mastodons enjoyed the now-Greater Cincinnati area so much they likely were year-round residents and not nomadic migrants as previously thought. Findings indicate each species kept to separate areas based on availability of favored foods at the southern edge of the Last Glacial Maximum's major ice sheet.
