Long-standing climate paradox resolved
(Phys.org) —Climate scientists have long documented the strong control of Earth's orbital variations on the waxing and waning of the great ice ages, when huge "pluvial" lakes filled the valley floors of the Great Basin. For years it was thought that Great Basin climate marched to the tune of a different drummer. This paradox arose from an iconic climate record from Devils Hole, Nev., which suggested that Great Basin climate warmed out of glacial periods before warming from changes in the earth's orbit. However, in a new study, "Orbital control of western North America atmospheric circulation and climate over two glacial cycles," published today in the online journal Nature Communications, scientists revealed a 175,000 year-long climate record from Great Basin that shows ice age temperature oscillations centered around changes in earth's orbit. The climate history was constructed from cave deposits that were collected between 2011-13 in Nevada – areas included Pinnacle Cave on Mt.
Saudi Arabia may go broke before the US oil industry buckles
King Salman bin Abdulaziz Al Saud Photo: Andrew Harnik/Reuters If the oil futures market is correct, Saudi Arabia will start running into trouble within two years. It will be in existential crisis by the end of the decade. The contract price of US crude oil for delivery in December 2020 is currently $US62.05, implying a drastic change in the economic landscape for the Middle East and the petro-rentier states. The Saudis took a huge gamble last November when they stopped supporting prices and opted instead to flood the market and drive out rivals, boosting their own output to 10.6 million barrels a day (b/d) into the teeth of the downturn.

If the aim was to choke the US shale industry, the Saudis have misjudged badly, just as they misjudged the growing shale threat at every stage for eight years. One Saudi expert was blunter. The problem for the Saudis is that US shale frackers are not high-cost.
Could Plastic “Lego” Roads Pave The Way To A Greener Future?
Some adults never “grow up,” and it seems that these engineers still have their minds in the toy box. They have designed “road blocks” that are like enormous Lego pieces, able to be snapped in and out of place easily. Even better, they're designed to be made from recycled plastic dredged from the oceans. The road to success is always under construction. The city of Rotterdam in the Netherlands is teaming up with the company VolkerWessels to create prototype plastic roads. Naturally, when designing roadways that would reasonably support hundreds or even thousands of cars a day, structural integrity would be a concern. A design of PlasticRoad. The prefabricated roads would be made in a factory, transported to the installation site and then slotted into place. This project is ambitious and it may be years before we find out if the pre-fabricated plastic is road-worthy and can replace traditional tar and asphalt roads.

How Newsweek's 'global cooling' story got its legs
Jan. 10, 2014 Nine paragraphs written for Newsweek in 1975 continue to trump 40 years of climate science. It's a record that has the author amazed. ShareThis By Doug StruckThe Daily Climate BOSTON – Temperatures have plunged to record lows on the East Coast, and once again Peter Gwynne is being heralded as a journalist ahead of his time. Gwynne, now 72, is a bit chagrinned that a long career of distinguished science and technology reporting is most remembered for this one story. Gwynne was the science editor of Newsweek 39 years ago when he pulled together some interviews from scientists and wrote a nine-paragraph story about how the planet was getting cooler. Ever since, Gwynne's "global cooling" story – and a similar Time Magazine piece – have been brandished gleefully by those who say it shows global warming is not happening, or at least that scientists – and often journalists – don't know what they are talking about. Fox News loves to cite it. Popping up - again and again Donald J.
Kinetic energy may power our home and gadgets starting in 5 years
In the next five years your shoe may be what powers the battery in your cell phone. Engineers are harnessing the power of kinetic energy and one IBM employee thinks widespread usage of the technology isn’t far off. Harry Kolar, an engineer with IBM, described harvesting energy from human movements as bodies becoming “an energy-generating machine,” in a blog post about what energy changes may occur in the next five years. In essence, we create energy from many of the little activities we do throughout the day. “This science — parasitic power collection — pulls and transmits energy created by the slightest movement.” said Kolar in the blog post. Kolar also predicts that we will figure out how to best harness wave and tidal energy. “My team is working with The Sustainable Energy Authority Ireland to use real-time streaming analytics that monitor the underwater noise and track its potential impact on the marine environment,” said Koler.
Упражнения для зрения
Слабым зрением уже никого не удивишь. С появлением телевизоров и компьютеров эта болезнь распространилась по всему земному шару, заставляя медиков и ученых придумывать всë новые методики по коррекции зрения. Однако больше всего от этой напасти страдают дети. Насмешки, обидные прозвища и ярлык «очкарик» не только ранят маленькую детскую душу, но и прививают комплексы, которые могут преследовать всю жизнь. Ежедневно выполняя эти упражнения, ты добьешься замечательных результатов уже через неделю. 1. В светлое время суток на открытом пространстве (то есть вне помещения) выбери объект для занятий. 2. Находясь вне помещения в светлое время суток, поочередно (с частотой примерно одна мишень за одну секунду) выбирай взглядом различные объекты (мишени), находящиеся на самом разном удалении (от кончика носа до горизонта). 3. 4. Прикрой глаза веками и приложи к лицу сложенные лодочками кисти рук. 5. Вне помещения в светлое время суток выбери объект для упражнения. 6. 7. 8. 9. Внимание!
