    Elon Musk discusses his vision for how he plans to colonize Mars

    Musk said a crewed mission to Mars could happen in 10 years, "if things go super well." The sources of funding for this endeavor will include private sector and government investors, profits from servicing the international space station and launching satellites, and Musk's own money, among others. "The reason I am personally accumulating assets is to fund this," Musk said. And once there, there would be no shortage of jobs, since "Mars would have a labor shortage for some time," he said. The ship would depart every 26 months, when the distance between Earth and Mars is closest. It would be made in large part of carbon fiber and fueled by methane, which can be synthesized using elements available

    Pillar of Obama climate plan has its day in court

    The cornerstone of President Barack Obama's drive to fight global warming underwent close scrutiny Tuesday in a high-stakes day in court. The so-called Clean Power Plan, approved last year, sets state-by-state emissions targets for existing power plants and aims to reduce America's output of CO2 by nearly a third by 2030 as compared to 2005 levels. The court's action raised doubts about America's contribution to a historic accord to fight global warming, reached in December in Paris, and infuriated environmentalists around the world.

    Asia's poor choking on filthy air

    Polluted air is a "public health emergency", the World Health Organization said Tuesday, adding nine out of 10 people globally breathe bad air that is blamed for more than six million deaths a year. Southeast Asia and the Western Pacific region -- including China -- are the hardest hit, the data showed. South Asia is also badly affected, with the WHO saying poor air quality is responsible for the deaths of more than 600,000 people in India and 37,000 people in Bangladesh every year.

    Meet the nuclear cattle of Fukushima

    Nuclear Cattle On March 11 2011, a 15-meter tsunami triggered by a 8.9-magnitude earthquake, disabled the Fukushima Daiichi nuclear power plant in Fukushima, causing a nuclear accident. Residents within a 20 km radius of the facility were forced to evacuate their homes and leave behind their livelihoods and possessions. Before leaving, some farmers released their cows so they could roam free and survive in the nuclear fallout-affected area. 1,400, however, died from starvation, while the government euthanized 1,500 more. Since 2011, Matsubara has documented both the relationship six farmers have with their surviving herds as well as an ongoing study examining the effects radiation has on large

    One of the original 'power posing' researchers now says its effects aren't real

    Authored by Dana Carney and Andy Yap, then of Columbia University, as well as Amy Cuddy of Harvard, the study suggested that standing like Wonder Woman for two minutes could raise testosterone levels and reduce stress hormone levels temporarily. Cuddy gave a TED talk on power posing in 2012 that has been viewed 46 million times, and she's built a lucrative business based partly on the research that power posing works. Dana Carney, who today serves as a professor at the Haas School of Business at the University of California, Berkeley, recently published a report renouncing the effects of power posing.

    A Rare Black Moon Will Rise In the Sky on Friday Night

    When it comes to rare lunar events, September 2016 seems to be the month that keeps on giving: This Friday, September 30, a Black Moon will rise in the skies of the Western Hemisphere, a phenomenon we haven't seen since March 2014. The Black Moon, which will occur at 8:11 p.m. ET on Friday, will only be happening in the Western Hemisphere because, technically, the new moon will happen on October 1 for the Eastern Hemisphere (they'll be getting their Black Moon at the end of next month). The next time we'll see a second new moon in a single calendar month in the Americas will be July 2019.

    Study May Give New Respect to Our Milky Way Neighborhood

    Our corner of the Milky Way galaxy may be a bigger deal than scientists thought. The galaxy is shaped like a disk, with four major arms of stars, dust and gas spiraling out from the center. Our solar system lies at the edge of what's called the Local Arm, which resembles a separate piece of an arm. Historically, the Local Arm "didn't get much respect.... People thought it was just a tiny little thing," says Mark Reid of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts. But a new paper he co-authored concludes it is bigger than scientists thought. Researchers calculated that it stretches more than 20,000 light-years long, maybe about four times what scientists had thought

    Cave fires and rhino skull used in Neanderthal burial rituals

    BURNING through the darkness, the fires would have lit up the cave around where the young child lay. The remains of a series of small fires discovered within a dolomite hillside 93 kilometres north of Madrid, Spain, could be the first firm evidence that Neanderthals held funerals. The blackened hearths surround a spot where the jaw and six teeth of a Neanderthal toddler were found in the stony sediment. Puzzlingly, within each of these hearths was the horn or antler of a herbivore, apparently carefully placed there. In total, there were 30 horns from aurochs and bison as well as red deer antlers, and a rhino skull nearby. Archaeologists believe the fires may have been lit as some sort of funeral

    Over 90% of world breathing bad air: WHO

    Nine out of 10 people globally are breathing poor quality air, the World Health Organization said Tuesday, calling for dramatic action against pollution that is blamed for more than six million deaths a year. New data in a report from the UN's global health body "is enough to make all of us extremely concerned," Maria Neira, the head of the WHO's department of public health and environment, told reporters. Poorer countries have much dirtier air than the developed world, according to the report, but pollution "affects practically all countries in the world and all parts of society", Neira said in a statement.

    Big Earthquakes May Be More Likely During New and Full Moons

    Every two weeks, on the full and new moons, the sun, moon and Earth fall along a nearly straight line. The combination of gravitational forces in this arrangement creates large swings in the tides. But the celestial alignment affects more than the oceans—it also tugs on Earth’s crust, adding to the stress on faults. This makes it more likely that major earthquakes will strike at these times, according to a new study. The idea isn’t new, but scientists have had a hard time testing the earthquake-tide relationship. For instance, three of the largest earthquakes in recent years happened when tidal stress was high. But those big ones are rare and the link seems to break down for smaller events. So

    Scientists fix fractures with 3D-printed synthetic bone

    By Kate Kelland LONDON (Reuters) - Scientists in the United States have successfully treated broken spines and skulls in animals using 3D-printed synthetic bone, opening the possibility of future personalized bone implants for humans to fix dental, spinal other bone injuries. Unlike real bone grafts, the synthetic material - called hyper-elastic bone - is able to regenerate bone without the need for added growth factors, is flexible and strong, and can be easily and rapidly deployed in the operating room. Giving details in a teleconference, the scientists said the results of their animal trials - published on Wednesday in the Science Translational Medicine journal - were "quite astounding".

    Evolution of large dinosaurs linked to development of bony cranial ornaments

    London –  The evolution of gigantic theropod dinosaurs such as "Tyrannosaurus rex" was linked to the development of exaggerated cranial ornaments such as crests and horns, a study published Tuesday said. Researchers from the University of North Carolina concluded in a study published in "Nature Communications" magazine that non-avian theropod species possessing ornaments developed larger body sizes than unadorned lineages. Phyletic giantism _ an evolutionary trend toward large size _ can thus be linked to the possession of cranial ornamentation, the study said. The paper found a clear correlation between the evolution of large-sized bodies and the appearance of osseous ornaments, whose "origin and influence across macroevolutionary time scales remains poorly understood for virtually all animals," according to the study.

    As drought grips Iran, farmers lament loss of a way of life

    Watermelons once sprung from this soil, the giant striped fruit dotting the arid landscape like mushrooms after a rain. “It was such a garden,” farmer Hossain Mirakhouri, 45, recalled of his childhood on this sun-scorched plateau east of Tehran. Now nothing remains of his family’s patch of watermelon, a water-hungry crop that Mirakhouri can no longer afford to grow in increasingly dry conditions. He and his brothers, who farm a 2-acre homestead by hand much as their ancestors did, have switched to growing barley and genetically modified cotton, which they say have lower water requirements.  “The amount of land that is cultivable shrinks year in, year out,” said Mirakhouri, sweat beading on his

    Have CO2 levels reached a point of no return?

    Earth may have passed a significant symbolic threshold as the global climate continues to grow warmer. Usually, September marks a low in the amount of carbon dioxide (CO2) in the atmosphere. This concentration sets the bar over which levels of the greenhouse gas will fluctuate throughout the next year. But this September, CO2 levels are staying high, at around 400 parts per million, and many scientists think that we will not see levels of the greenhouse gas drop below that threshold within our lifetimes. Earth has been steadily building up CO2 in the atmosphere since the Industrial Revolution, but the 400 ppm landmark is creating a new normal that hasn't been seen on this planet for millions

    WSU research leads to algae treatment for blindness

    In a coup for Wayne State University’s reputation as a research center, a small eye-care company that uses green algae genes to treat a type of human blindness has sold for $60 million. The company, RetroSense Therapeutics, which is now based at the Ann Arbor SPARK business accelerator, was acquired this month by Allergan, a $4 billion-a-year maker of skin and eye care products. The company's treatment uses a virus to deliver a photoreceptor gene from the algae into a human patient's eye. The research, which aims to cure an inherited disease that causes people to slowly go blind, has shown promise. The Federal Drug Administration gave permission for a clinical trial.

    Materials programmed to shape shift

    Scientists have pre-programmed materials to change their shape over time. Previous shape-shifting materials have needed some external trigger to tell them to transform, like light or heat. Now, a US-based team has encoded a sequence of shape transformations into the very substance of a polymer, with each change occurring at a pre-determined time. Details appear in Nature Communications journal. The principles could be applied in implants that deliver medicine from within the human body and the technology could also see use in heavy industry. Professor Sergei Sheiko from the University of North Carolina at Chapel Hill, and colleagues introduced two types of chemical bond to their polymer: permanent

    Elon Musk outlines Mars colonization plan

    By Irene Klotz GUADALAJARA, Mexico (Reuters) - SpaceX is developing a massive rocket and capsule to transport large numbers of people and cargo to Mars with the ultimate goal of colonizing the planet, company chief and tech billionaire Elon Musk said on Tuesday. Musk outlined his plans for the Mars rocket, capable of carrying 100 passengers plus cargo per voyage, even as SpaceX is still investigating why a different rocket carrying a $200 million Israeli satellite blew up on a launch pad in Florida earlier this month. "You can't create a self sustaining civilization if the ticket price is $10 billion per person," he said during a presentation at the International Astronautical Congress meeting in Guadalajara.
