TEHRAN (FNA)- Researchers have designed a recyclable plastic that, like a Lego playset, can be disassembled into its constituent parts at the molecular level, and then reassembled into a different shape, texture, and color again and again without loss of performance or quality Light yet sturdy, plastic is great -- until you no longer need it. Because plastics contain various additives, like dyes, fillers, or flame retardants, very few plastics can be recycled without loss in performance or aesthetics. Even the most recyclable plastic, PET -- or poly(ethylene terephthalate) -- is only recycled at a rate of 20-30%, with the rest typically going to incinerators or landfills, where the ...

For years, João Duarte has puzzled over a seemingly boring underwater expanse off the coast of Portugal. In 1969, this site spawned a massive earthquake that rattled the shore and sparked a tsunami. But you would never know why just from looking at the broad, featureless surface of the seabed. Duarte, a marine geologist from the Instituto Dom Luiz at the University of Lisbon, wanted to find out what was going on. Now, 50 years after the event, he may finally have an answer: The bottom of the tectonic plate off Portugal's coast seems to be peeling away from its top. This action may be providing the necessary spark for one plate to start grinding beneath another in what's ...

For the first time in decades, it's hard to ignore the threat of nuclear war. But as long as you're far from the blast, you're safe, right? Wrong. In this sobering talk, atmospheric scientist Brian Toon explains how even a small nuclear war could destroy all life on earth -- and what we can do to prevent it. A professor in the Department of Atmospheric and Oceanic Sciences at the University of Colorado-Boulder, Brian Toon investigates the causes of the ozone hole, how volcanic eruptions alter the climate, how ancient Mars had flowing rivers, and the environmental impacts of nuclear war. He contributed to the U.N.’s Nobel Peace Prize for climate change and holds numerous ...
Engineers Make Injectable Tissues a Reality

TEHRAN (FNA)- A simple injection that can help regrow damaged tissue has long been the dream of physicians and patients alike. A new study from researchers at UBC Okanagan moves that dream closer to reality with a device that makes encapsulating cells much faster, cheaper and more effective. "The idea of injecting different kinds of tissue cells is not a new one," says Keekyoung Kim, assistant professor of engineering at UBC Okanagan and study co-author. "It's an enticing concept because by introducing cells into damaged tissue, we can supercharge the body's own processes to regrow and repair an injury." Kim says everything from broken bones to torn ligaments ...
World In Midst of Carbon Drought (w/ Prof. William Happer, Princeton University)

We’re in a carbon drought. That is according to Professor William Happer of Princeton University. The renowned physicist says when it comes to carbon dioxide, there’s more good than bad. He goes on to say most of carbon dioxide’s effect has already happened. He points to the logarithmic dependence of temperature on carbon dioxide levels. Happer says the unique properties of carbon dioxide mean that current levels would need to double for another one-degree increase in temperature and they’d have to double again for another one degree rise. --- Simon Fraser University’s Centre for Dialogue presents Conversations That Matter.

Using a special gene-editing technique they developed, the Chinese researchers were able to “enhance” the brain capacity of rhesus macaques monkeys, making them more “human-like” by adding an extra infusion of smarts, as well as enhanced memory capabilities. Known as MCPH1, the altered gene reportedly caused the monkeys’ brains to develop in a more human-like manner, with results that included improved reaction times, better short-term memory, and other human-like abilities. Following the success of this experiment, the research team decided to clone MCPH1 in order to produce a total of 11 transgenic rhesus monkeys – the goal being to create a practical ...

US F-22s came face-to-face with Russia's top fighter near Alaska and were at a major disadvantage US F-22 stealth fighter jets intercepted Russian Tu-95 bombers and Su-35 fighters that approached Alaska on Tuesday, and it highlights a downside to the US's top fighter jets. The F-22, with its incredible acrobatic abilities in the air and all-aspect stealth cloaking it from enemies at a distance, is the US's most lethal combat plane. While the F-35 was built as a flying quarterback that can dogfight, bomb ground targets, gather intelligence, or conduct surveillance, the F-22 specializes in one thing: air-to-air combat. But with today's rules of engagement, the F-22's ...

When he refused to surrender, the soldiers set the barn on fire, before shooting at him as he moved about inside. Booth, a famous stage actor admired across the country, was fatally wounded in the neck and dragged from the barn, dying three hours later, aged 26. Or at least that is how history has recorded the fate of the man who assassinated America’s most ...

A new study published by Germany’s leading publicly-funded economic think-tank has proven electric cars are overall increase CO2 emissions and leave far more damaging waste products than traditional vehicles—showing that even this demand for “green” energy is a hoax. The report, prepared and published by researchers at the Ifo Institute for Economic Research at the University of Munich, said that when the CO2 emissions resulting from the production of the batteries and the electrical generation required to power these vehicles are taken into account, an e-car will increase damage to the environment by up to 28 percent more than a diesel engine.

Sleep scientist Matthew Walker has observed that “human beings are the only species that deliberately deprive themselves of sleep for no apparent gain.” We stay up late to watch our favorite TV shows. We wake up early to get to work or school on time. And twice a year we change our clocks, to the bewilderment of our circadian rhythms. We also set up conflicts between our natural and social clocks in other, less obvious ways, a fact underscored in research published this month in the Journal of Health Economics. It turns out, the study found, that living on the wrong side of a time zone’s boundary can have negative consequences on a person’s health and wallet. The ...

ECNS...Chinese scientists have found a cheaper way to produce hydrogen energy by developing a new catalyst. The catalyst was developed by scientists from the University of Science and Technology of China, who used an alloy to improve the activity and stability of a kind of precious metal catalyst. The new catalyst can greatly cut the cost of hydrogen production through electrolysis of water compared with Iridium dioxide, a catalyst that is widely used in production, according to the researchers. As a clean energy, hydrogen has huge potential in industries including new energy vehicles and electricity generation. The research on the catalyst provides a new direction for other similar ...

Just about every two years, the planet Mars makes its closest approach to Earth... around 36 million miles. That's when we pack our robotic emissaries off to the Red Planet, timing their launches to spend the least effort to get there. Some fly around it... snapping pictures... Others land ... to sample its surface.... ...a few to crawl around its canyons and craters. These probes may pave the way for human explorers... and, perhaps permanent settlers... who'll dig deeper still... in search of answers to our most pressing question: Did Mars develop far enough -- and stay that way long enough -- for life to arise? And, if so, does anything live now within Mars' dusty ...
