Researchers looked at climate models to see how aerosolized fossil fuels could be changing rainfall patterns and causing droughts.
For when you want to visit space, but you don't want to do all that astronaut training.
California's vast San Joaquin Valley, the country's most productive farming region, is engulfed by some of the nation's dirtiest skies, forcing the state's largest air district to spend more than $40 billion in the past quarter-century to enforce hundreds of stringent pollution rules. The investment has steadily driven down the number of days with unhealthy air — but on hot, windless days, a brown haze still hangs overhead, sending wheezing people with tight chests to emergency rooms and hundreds each year to an early grave. Despite the air district's efforts, the valley's air still violates federal standards for sooty pollution that comes from industry, businesses and vehicles.
This week, the surrealist painter Salvador Dali is being exhumed from his grave in Figueres, northeastern Spain, where he has lain beneath the stage of a museum since his death in 1989. Researchers hope to collect DNA from his skeleton in order to settle a paternity suit brought by a tarot card reader named Pilar Abel, who claims that her mother had an affair with the artist while working as a maid in the seaside town where the Dalis vacationed. If the claim is substantiated, Abel may inherit a portion of the $325 million estate that Dali, who was thought to be childless, bequeathed to the Spanish state upon his death. The grave opening may seem like a fittingly surreal turn of events, but advances in DNA research and other scientific techniques have recently led to a rise in exhumations.
A look at some of the state-of-the-art features in the USS Gerald Ford, the latest warship to join the Navy’s impressive fleet
No modern American president has been more hostile to federal support for the sciences than Donald Trump. In the six months since he became president, he’s fired scientists, removed scientific data from federal websites, proposed a budget that deeply cuts research and appointed science skeptics to head the Environmental Protection Agency and the Department of Energy. But what actually happens when a government systematically withdraws support -- financial, institutional and even rhetorical -- from the scientific community? Beginning 10 years ago, in an eerily familiar experiment, Canada under Conservative Prime Minister Stephen Harper embarked on just such an assault, muzzling scientists, gutting
The discovery of globally significant artifacts in Australia has ignited the world’s imagination about what life was like 65,000 years ago. Previously it was thought the continent was inhabited by megafauna — huge kangaroos that towered over humans and wombats the size of rhinos — but items found in an archaeological site in the Northern Territory show humans may have lived alongside these massive animals for at least 20,000 years. One of the researchers who helped find and date the items, Professor Zenobia Jacobs of the University of Wollongong said the findings published in the journal Nature this week were of global significance. Researchers found more than 10,000 artefacts buried in what they call the basal (or first occupation) layer under a rock shelter called Madjedbebe near Kakadu National Park.
In a potentially historic move, the coastal Californian counties of Marin and San Mateo, together with the City of Imperial Beach, have each filed a lawsuit against 20 of the world’s largest fossil fuel producers. The claims allege that by extracting, marketing and distributing oil, coal and gas, the companies have engaged in conduct that has and will continue to cause rising sea levels. The claims say the resulting floods interfere with public and private property and affect the rights of coastal residents in the US state to health, safety, peace, comfort
From capturing planets in various angles to exploring the infinite space, and even landing on Moon, mankind’s fascination and curiosity for the mysteries of the universe has lead to several path-breaking discoveries. Starting right from the launch of Sputnik, in 1957, space agencies have managed to explore many parts of the universe and still continue to do so.
According to NASA, experiencing a total solar eclipse where you live happens about once in 375 years. So, unless modern medicine advances considerably in the next few years, you might not make it to the next one. The last time anyone in the United States witnessed a solar eclipse was almost 40 years ago, on February 26, 1979. It's been even longer -- 99 years -- since a total solar eclipse crossed the country from the Pacific to the Atlantic. The total eclipse on June 8, 1918, passed from Washington to Florida. You can set your clock to it, even to the precise second. Make your plans now. If you are reading this at work and want to ask for the day off, you will soon find that all of your science
The painstaking search for missing flight MH370 has uncovered a previously unknown undersea world of volcanoes, deep valleys and soaring ridges, according to detailed maps released by Australia. Although no trace of the Malaysia Airlines plane was found during the search in the southern Indian Ocean -- the most expensive ever of its kind -- large volumes of data showing a detailed picture of the sea floor had to be collected to guide the probe. "It is estimated that only 10 to 15 percent of the world's oceans have been surveyed with the kind of technology used in the search for MH370," Geoscience Australia's environmental geoscience chief Stuart Minchin said late Wednesday.
First there was Cecil, a Zimbabwean lion whose allegedly illegal killing by an American hunter in 2015 ignited international outrage. Now Cecil's son Xanda has been legally killed in the same area, bringing fresh scrutiny on the "trophy" hunting of a species whose numbers in the African wild have plummeted. Some conservation groups denounced 6-year-old Xanda's killing, saying commercial hunting bans and robust wildlife tourism in countries such as Kenya and Botswana are among the best ways to protect threatened species.
The closer that economists look at the rise in income inequality, the more they find one cause may be the rise of another inequality: The least productive firms are falling further behind the most productive firms. This point was made in a recent study spanning 16 countries by the Paris-based Organization for Economic Cooperation and Development. It found the “productivity gap” between firms in the top 10 percent by productivity and those in the bottom 10 percent rose by about 14 percent from 2001 to 2012.
The House of Lords has launched a public inquiry into advances in the field of artificial intelligence (AI). Well-known scientists and entrepreneurs such as Stephen Hawking and Elon Musk have warned about the potential dangers superintelligent AI presents. Is the current level of excitement surrounding artificial intelligence warranted?
Groups that represent industries from farming to fracking are supporting a legislative push to rewrite how government handles science when drawing up regulations. And the whole effort has scientists worried. Consider, for example, the Honest and Open New EPA Science Treatment Act, or HONEST Act, which passed the House in the spring and now is with the Senate. Just how "honest" it is depends on whom you ask. The HONEST Act says the EPA can't take a particular action based on scientific research unless that research is "publicly available online in a manner than is sufficient for independent analysis and substantial reproduction of research results." Trouble is, making all that data widely available
Yesterday, the Trump administration formally named its candidate for the Department of Agriculture's undersecretary of research, education, and economics, a post that serves as the agency's chief scientist. Its choice? Sam Clovis, who has no scientific background but is notable primarily for having been a conservative talk-radio host. If approved by the Senate, the US' attempts to understand climate change's impact on agriculture will be led by someone who called climate research "junk science." Clovis, who has also taught economics and management at an Iowa liberal arts college, was an early supporter of Trump's candidacy. He's been working at the USDA as a White House advisor since shortly
July 20, 1969 — Neil Armstrong and Buzz Aldrin descended from the Apollo 11 capsule to become the first humans to ever walk on the moon. On Sept. 9, 2002, Buzz Aldrin decide he had finally had enough of Bart Sibrel's moon landing hoax conspiracies and punched Sibrel right in the face.
Peruvian authorities have revealed the reconstructed face of the Lord of Sipan, a pre-Columbian ruler whose remains were discovered in 1987 and hailed as one of the country's most stunning archaeological finds. A full body representation of the ancient ruler, believed to have died around the year 250, was unveiled Thursday at the Museum of the Royal Tombs of Sipan in the northern city of Chiclayo. Peruvian Culture Minister Salvador del Solar traveled to Chiclayo for the unveiling, which marks the 30th anniversary of the tomb's discovery.
On August 21, the continental United States will see its first total solar eclipse in 38 years. The shadow of the moon will cross the country, touching land in Oregon and leaving from South Carolina, providing an opportunity for what may be an unprecedented number of people to witness this extraordinary natural phenomenon. Total solar eclipses are a big deal not because of how infrequent they are — there’s a total solar eclipse every 18 months on average — but because of how little of the Earth’s surface falls in the path of any given eclipse shadow. The next total solar eclipse to visit the US will be in 2024. If an eclipse happens to come to your town, you’re lucky. Any given location will
Deep under Shanghai, workers on a flood-lit construction rig carefully install massive concrete wall sections for a new subway tunnel, adding metre-by-metre to the world's longest metro system. In 2001, four mainland Chinese cities including Beijing and Shanghai had rather limited networks. State media reports say Chinese spending on subway construction could top 2 trillion yuan ($295 billion) from 2016-2020 alone.
Wildlife researchers in Cambodia have found a breeding location for the masked finfoot, one of the world's most endangered birds, raising hopes of its continuing survival. The New York-based Wildlife Conservation Society said Thursday its scientists, along with conservationists from Cambodia's Environment Ministry and residents along the Memay river in the Kulen Promtep Wildlife Sanctuary, discovered the only confirmed breeding location in Cambodia for the very rare species. The International Union for Conservation of Nature has placed the bird on its red list of globally endangered species because its worldwide population of less than 1,000 is declining at an alarming rate.
In my previous blog post we considered the general weighted moving average. In this post we aim to give an overview of some specific types of moving averages. Specifically, we cover “ordinary” moving averages and mention some examples of exotic moving averages.
Jude Sparks was out on a family hike in the desert near Las Cruces, N.M., testing walkie-talkies, when the then-9-year-old boy tripped over a rocky protrusion. When Jude got up again, he examined what appeared to be two large, fossilized teeth jutting out from the terrain. Farther up, he spotted what looked like a tusk, he added. Jude was intrigued. But Jude's brother Hunter, who had been running behind him, didn't seem too impressed with whatever Jude had found. “Hunter said it was just a big, fat rotten cow,” Jude told KVIA News, which first reported the story. “I didn't know what it was. I just knew it wasn't usual.” The boys' parents photographed the curious mass, then helped Jude look up
Fox Firepower: The US Air Force celebrated its 70th Birthday at the 2017 RIAT event, showing off a wide range of outstanding aircraft including the B-52 Stratofortress, B-2 bomber and the U-2 spy plane
The “national security space structure is broken,” declared Rep. Mike Rogers (R-Alabama; no relation), whose proposal to create a U.S. Air Force “space corps” recently passed the House Armed Services Committee by a vote of 60-1. Rep. Rogers argued that the Pentagon’s space activities should not be led by officers and executive staff who “get up each morning thinking about fighters and bombers…you cannot organize, train, and equip in space the way you do a fighter squad.” Perhaps, a true statement. On a more bureaucratic level, he echoed a recent Government Accountability Office report that lamented “DOD’s culture has generally been resistant to changes in space acquisition approaches and that fragmented responsibilities have made it difficult to coordinate and deliver interdependent systems.” Here too I would not necessarily disagree. If the Department of Defense and Air Force were idle, perhaps such sweeping legislatively driven reform would be necessary.
