A group of Mexican engineers have created technology to recover and purify, either seawater or wastewater from households, hotels, hospitals, commercial and industrial facilities, regardless of the content of pollutants and microorganisms in, incredibly, just 2.5 minutes.
Researchers have shown how air bubbles could keep sediments from obstructing bends in river...
Scientists have discovered a way to make trees grow bigger and faster, which could increase...
Humans may be able to communicate positive emotions like happiness through the smell of our sweat, according to new research that indicates we produce chemical compounds, or chemosignals, when we experience happiness that are detectable by others who smell our sweat. The study also showed that being exposed to sweat produced under happiness induces a contagion of the emotional state.
Researchers have developed a statistical model that allows them to tell where a dust sample came from within the continental U.S. based on the DNA of fungi found in the sample. The primary goal of the research was to develop a new forensic biology tool for law enforcement or archeologists. But it may also give us a greater understanding of the invisible ecosystems of microbial life.
Some consumer groups concerned about the safety of synthetic preservatives such as parabens have pushed for natural alternatives. Industry has responded with a slew of options, including preservatives from kimchi, a popular Korean staple. But scientists have found that a “natural” preservative made from radish kimchi contains synthetic ingredients.
The rainbow-hued shimmer of fish scales, bird feathers and insect bodies that change color and brightness depending on viewing angle can be mesmerizing, but biologists have long debated the purpose of the displays. New research suggests that, for some organisms, iridescence evolved as an anti-predator defense to dazzle and confuse predators with sudden shifts in color and brightness in a bid to gain a few precious moments for escape.
Monitoring Europe’s vast nature protection areas used to be extremely difficult. Thanks to computer algorithms, this can now be done using aircraft and laser technology.
Citrus fruits are among the most important commercially cultivated fruit trees in the world, yet little is known of the origin of the citrus species and the history of its domestication. Now, researchers have performed the largest and most detailed genomic analysis on 30 species of Citrus— representing 34 citrus genotypes— and used chloroplast genomic data to reconstruct its evolutionary history.
Fisheries managers have decided to call off the West Coast sardine fishing season that starts in July because of rapidly dwindling numbers, hoping to save an iconic industry from the kind of collapse that hit in the 1940s and lasted 50 years.
Scientists have found a key ingredient in aspirin and anti-pimple products, salicylic acid, is a cost-effective plant growth and survival improver during a world-first desert restoration trial in Saudi Arabia.
About 5,500 more people could survive a major tsunami hitting the Pacific Northwest if they just walk a little faster to higher ground after roads are knocked out, a new study shows. The report looked at 73 communities along 700 miles of coastline in Oregon, Washington and Northern California.
A technology has the potential to revolutionize the sourcing of renewable energy from rivers. A software app automatically selects appropriate locations in rivers to site a large range of micro renewable hydro-power turbines and determines the environmental sensitivity of the location.
A new analysis of the chemical make-up of meteorites has helped scientists work out when the Earth formed its layers. The research by an international team of scientists confirmed the Earth's first crust had formed around 4.5 billion years ago.
Frozen Arctic and sub-Arctic soil that thaws from global warming will add substantial amounts of carbon to the atmosphere in the form of greenhouse gases, accelerating climate change the rest of the century, but it won't come in a sudden burst, researchers say in a new paper.
Invertebrates perform essential functions for the smooth running of the ecosystems in tropical forests. Nearly a half of all tropical rainforests worldwide have been logged, and this often causes heavy changes to the number and type of invertebrates, with many species being lost from the ecosystem.
Traffic fumes, dirty air blown in from Europe and Sarahan dust are combining to coat parts of Britain in smog. The environment department says air pollution is "high" across much of the country Friday and could reach the top designation of "very high" in southeast England.
Consumers whose drinking water can be contaminated by the release of untreated wastewater after heavy rains face increased risk for gastrointestinal illness. “Combined” sewer systems collect both sewage and stormwater runoff on the way to treatment facilities.
What we eat has a big influence on our environment, in ways beyond the typical carbon footprint questions of local vs. imported or animal vs. vegetable. Researchers have found that what we choose to eat– and what we excrete as waste– can influence the nutrient cycle on a large scale.
California saw a record number of deaths from the West Nile virus last year, and the state's drought may have contributed to the spike in infections. Thirty-one infected people died in 2014, the most since California began recording West Nile cases in 2003.
Several members of Congress are heading to the mothballed site of a proposed radioactive waste dump in the Nevada desert amid new talk about a decades-old problem— where to dispose of spent nuclear fuel stored at commercial reactors around the U.S.
Scientists from Southern Methodist Univ. have helped a Dallas zookeeper and his five-year-old son excavate a dinosaur fossil they found behind a grocery store in the Dallas-Fort Worth area.
Shark researchers are asking for the public's help to identify and record shark sightings from around the world, using their new citizen science project, SharkBase, a new global shark encounter database established to assist in the process of mapping the distribution of sharks worldwide.
The discovery of antibiotics produced by soil fungi and bacteria gave the world life-saving medicine. But new antimicrobials from this resource have become scarce as the threat of drug resistance grows. Now, scientists have started mining lakes and rivers for potential pathogen-fighters, and they’ve found one from Lake Michigan that is effective against drug-resistant tuberculosis.
A new study has revealed that inadequate access to pollen during larval development has lifelong consequences for honey bees, leading not only to smaller workers and shorter lifespans, but also to impaired performance and productivity later in life.
An American agave's job is to flower once and then die. One of the plants that called the Univ. of Michigan home for an unexpectedly long 80 years accomplished the former last year. Today, its life came to an end.
A scientist has developed a fertilizer for palm trees that should keep them healthy and reduce water pollution. An environmental horticulture professor found that applying a palm fertilizer with no nitrogen or phosphorus could prevent the harmful effects of lawn fertilizers on palms.
Now that most consumers download and stream their movies and music, more and more CDs and DVDs will end up in landfills or be recycled. But soon these discarded discs could take on a different role: curbing the release of greenhouse gases.
