    Professor fatally stabbed on USC campus, student arrested

    A graduate student arrested on suspicion of stabbing to death the professor who oversaw his work at the University of Southern California was being held on $1 million bail Saturday as their shocked colleagues began processing the news. David Jonathan Brown, a 28-year-old brain and cognitive science student, was arrested in the Friday afternoon attack in the heart of the Los Angeles campus. Brown was among just five students who worked in Tjan's lab that studied vision loss.

    Buzz Aldrin: Altitude Sickness Forced South Pole Evacuation

    Buzz Aldrin said he was evacuated from the South Pole last week because he became short of breath and began showing signs of altitude sickness. The 86-year-old adventurer, who was the second man to walk on the moon, released details on Sunday of his dramatic medical evacuation from Antarctica. He is continuing to recuperate in a hospital in Christchurch, New Zealand. Because of the thick ice that blankets Antarctica, the South Pole sits at an elevation of 2,835 meters (9,300 feet). Aldrin said in a statement he still has some congestion in his lungs and so has been advised to rest in New Zealand until it clears up and to avoid the long flight back to the U.S. for now. Aldrin, his son Andrew and

    A 58-story skyscraper in San Francisco is sinking — here's why it probably won't fall

    On November 25, new satellite images revealed that San Francisco's Millennium Tower can be seen sinking from space. Recent data provided by the European Space Agency suggests the building will continue to sink at a rate of two inches per year. The building's developers, Millennium Partners, hired engineers to drill holes around the building in order to test soil samples and figure out why the tower is sinking and what can be done to prevent it from sinking further.

    Four New Super-Heavy Elements Have Now Been Officially Christened

    Ununtrium, ununpentium, ununseptium, and ununoctium — these were the temporary names given to four new super-heavy elements by the International Union of Pure and Applied Chemistry (IUPAC) back in December. Now, a year later, these elements have been bestowed official names and have earned their spots in the periodic table. Earlier this week, the IUPAC — the organization in charge of naming and categorizing elements, among other things — revealed the official names of the four elements — nihonium (Nh), moscovium (Mc), tennessine (Ts), and oganesson (Og). The four elements, which have atomic numbers of 113, 115, 117 and 118, respectively, do not occur naturally and were created in labs. Once created,

    Editorial: Crime labs needs oversight

    Police and prosecutors call it “the CSI effect”: The unrealistic portrayal of forensic science in television dramas has conditioned jurors to expect — and give great credence to — crime-scene evidence tied to the accused through high-tech analysis. Sometimes, the key to identifying a murderer — and sending him to prison or death — is only few fibers, or maybe a single hair, blood patterns, a trace of poison, a boot mark or a tire track. “Wow,” says the viewer. “That’s unbelievable.” And, in real life, it might be: Forensic science is under attack as highly flawed, according to a recent Dispatch article. A lack of standards, training and verification of results is partly to blame. Other times,

    7 Ways That 'Star Trek' Changed the World

    The idea that Star Trek has changed the world might sound as farfetched as some of the USS Enterprise’s spacefaring missions, but the truth is that the science fiction series has directly or indirectly impacted both our present and future. It seems like an absurd statement — when creator Gene Roddenberry was first kicking around the idea in 1964, he probably never imagined that Star Trek would still be around in 2016 with reboots in the pipeline. Here are seven ways that Star Trek changed the world. 1.

    Scientists have long feared this ‘feedback’ to the climate system. Now they say it’s happening  |  Peak Oil News and Message Boards

    At a time when a huge pulse of uncertainty has been injected into the global project to stop the planet’s warming, scientists have just raised the stakes even further. In a massive new study published Wednesday in the influential journal Nature, no less than 50 authors from around the world document a so-called climate system “feedback” that, they say, could make global warming considerably worse over the coming decades. It has long been feared that as warming increases, the microorganisms living in these soils would respond by very naturally upping their rate of respiration, a process that in turn releases carbon dioxide or methane, leading greenhouse gases. “Our analysis provides empirical support for the long-held concern that rising temperatures stimulate the loss of soil C to the atmosphere, driving a positive land C–climate feedback that could accelerate planetary warming over the twenty-first century,” the paper reports.

    Human ancestor "Lucy" was a tree climber, evidence suggests

    She was discovered 42 years ago, but the 3-million-year-old human ancestor dubbed “Lucy” is still providing new insights on the human origin story. Now, new research suggests this predecessor to modern humans was an adept tree climber.  The evidence of Lucy’s tree-climbing habits was found in high-resolution CT scans of her fossilized bones, according to scientists from the Johns Hopkins University and the University of Texas at Austin. Those CT scans were intricately 3D printed, allowing for direct comparisons to the bones of early hominids, modern humans, and modern chimpanzees. The researchers’ work was published this week in the journal PLOS ONE.  Lucy’s arms were heavily toned, supporting

    Plans to Restore NASA Mission Control Room Remain in Limbo

    Plans to restore the NASA mission control room that served as the nerve center when man first reached the moon have been discussed for more than 20 years, but its restoration and preservation remain in limbo. Officials at Johnson Space Center in Houston say the restoration of Mission Operation Control Room 2 is a priority, but note that NASA has other priorities too. The room was designated a National Historic Landmark in 1985 and retired seven years later. The Houston Chronicle ( http://bit.ly/2g87794 ) reports that last month, Gene Kranz, a flight director during NASA's Gemini and Apollo missions, told a group of preservationists touring the room that it has been "worn of its heart and soul."

    Let’s Fight Back Against Poachers with a Robotic Rhino

    Since 2010, poachers in South Africa have killed more than 5,000 rhinos. In Asia, two rhino species—Javan and Sumatran—are critically endangered. According to the World Wildlife Foundation, poachers eager to reap their horns use helicopters and veterinary drugs to track and attack the animals. To save these animals’ lives, I propose the Ramakera: a robotic rhinoceros designed to monitor and protect the herd from poachers. I recently met with Canadian photographer and filmmaker Gregory Colbert, who gave me the idea of creating a biomimetic robot capable of protecting animals in the wild. The Ramakera would run on a long-lasting hydrogen fuel cell, and use hydraulics and servomotors to move its

    World's first polluted river flowed through Jordan 7,000 years ago

    Pollution today exists on a global-industrial scale, but a site in Jordan might be where it all began approximately 7,000 years ago, before the dawn of the Bronze Age, reports Phys.org. Researchers have uncovered evidence of what might have been history's first polluted river, a now-dry riverbed in the Wadi Faynan region of southern Jordan that appears to have flowed with slag, a waste product from smelting. "These populations were experimenting with fire, experimenting with pottery and experimenting with copper ores, and all three of these components are part of the early production of copper metals from ores," explained Russell Adams, from the Department of Anthropology at the University of Waterloo.

    Three bizarre (and potentially brilliant) ideas about music and health from TEDMED

    As it turns out, the theme of this year's TEDMED conference, an offshoot of the famous TED Talks, is “what if,” and all the attendees were walking around with name tags where they were asked to complete the question with their potentially world-changing thoughts. On stage at the conference, Jay Walker, chairman of TEDMED, delivered an absolutely fascinating walk-through of some of the rare manuscripts and books that he has in his personal Library of the History of Human Imagination. Through one of those artifacts — a journal containing data tables of deaths at a hospital in the 1840s — Walker told the tale of Ignaz Semmelweis, the guy who first imagined that caregivers at hospitals were spreading invisible germs to each other and other patients, leading to more disease.

    The Death Star would cost $7.8 octillion a day to run

    The British energy supplier Ovo has put some very well-spent hours into a comprehensive calculation of the operating costs of the Death Star, which will return to the spotlight in the December 16th movie Rogue One. To put that absurdly large number in perspective, $7.8 octillion is more than 100 trillion times the $70 trillion annual global economic activity of Earth, or 30 trillion times the roughly $200 trillion in wealth on our little blue planet. Ovo’s analysis, conducted in collaboration with physics blogger Stephen Skolnick and Dartmouth mathematics Professor Alexander Barnett, approaches the granularity of a good business model (if your business is blowing up planets to intimidate a rebellious populace).

    Why seabirds can’t stop eating plastic

    Photos of dead albatrosses filled to bursting with bright-colored bottle caps and knickknacks have become iconic in recent years, and one study even projected that nearly 99 percent of all seabirds will have eaten plastic by 2050. New research from the University of California Davis’s Bodega Marine Lab gives an explanation: Some seabird species may be gobbling up ocean plastics because they smell appetizing. “Before this, we sort of assumed that it was accidental ingestion,” said Lindsay Young, a wildlife biologist in Honolulu and the executive director of Pacific Rim Conservation. In a natural scenario, DMS gets released into the water when zooplankton or other forces break down microscopic marine plants, called phytoplankton.

Splurging on a vacation or other experience, on the other hand, may provide lasting happiness. Gilovich and his co-researchers, Amit Kumar and Jesse Walker, conducted several experiments to better understand how spending money in different ways affected a person’s emotions and behavior toward others.

    South Pole Noctilucent Cloud Season Begins Earlier Than Usual

    Every year, high in Earth’s atmosphere, wispy tendrils of noctilucent, or night-shining, clouds appear above the South Pole. Observations made using NASA’s Aeronomy of Ice in the Mesosphere (AIM) spacecraft have revealed that this year, the noctilucent cloud season in the Antarctic began earlier than usual — an observation that some scientists believe is a sign of the impact the inexorable build-up of greenhouse gases is having on Earth’s climate. This year the noctilucent cloud season began on Nov. 17, which ties with the earliest start yet in the AIM record of the Southern Hemisphere.

    Skywatch: Stars and planets brighten dark December days

    The luminous Venus starts December at a magnificent -4.2 magnitude (very bright), and you’ll find this picturesque planet in the southwestern heavens at dusk in the Sagittarius constellation now. By mid-month, the bubbly Venus appears to scoot rapidly toward the constellation Capricornus, and by the end of December, our neighboring planet becomes even brighter at -4.3 magnitude. After midnight, the large Jupiter now rises about 2:35 a.m. in the east and loiters in the eastern heavens until the rising morning sun washes this giant planet out of view. You’ll notice that Jupiter, which is -1.8 magnitude and quite bright, gets even brighter by mid-December as it rises in the east starting at 2 a.m. By the new year, this king of the planets rises at 1 a.m.
