PressTV... Theoretical physicist and cosmologist Stephen Hawking warns that if the human race does not leave the planet and start to live in space, humanity will die out. The renowned British scientist made the comments while giving a holographic speech at the Sydney Opera House in Australia, the Independent reported on Monday. "We must continue to go into space for the future of humanity," Hawking said, "I don't think we will survive another 1,000 years without escaping beyond our fragile planet." The eminent scientist used holographic technology to give the speech from his office in Cambridge, England. Stephen Hawking’s hologram and physicist Paul Daviesto ...

ScienceDaily... Hot vents on the seabed could have spontaneously produced the organic molecules necessary for life, according to new research by UCL chemists. The study shows how the surfaces of mineral particles inside hydrothermal vents have similar chemical properties to enzymes, the biological molecules that govern chemical reactions in living organisms. This means that vents are able to create simple carbon-based molecules, such as methanol and formic acid, out of the dissolved CO2 in the water. The discovery, published in the journal Chemical Communications, explains how some of the key building blocks for organic chemistry were already being formed in nature before life emerged -- ...

Science Alert... More evidence that the disease is much more than a mood disorder. Researchers from the UK have found evidence that depression doesn't just change our brains, it can also alter our DNA and the way our cells generate energy. A team from the Wellcome Trust Centre for Human Genetics investigated the genomes of more than 11,500 women, with the hopes of finding genes that might contribute to the risk of depression. But instead, they stumbled across a signature of metabolic changes in their cells that appears to have been triggered by the disease. The most notable discovery was that women who had stress-related depression - depression that's associated with some kind ...

Sputnik... The information necessary to hack a military drone is freely available to the public, in academic publications and online documents, according to an Israeli defense manufacturer. One such paper was published just a month before Iran claimed it downed a CIA stealth drone in 2011, Esti Peshin said Monday at the Defensive Cyberspace Operations and Intelligence conference in Washington DC. Peshin is the director of cyber programs for Israel Aerospace Industries. A 2011 study, titled "The Requirements for Successful GPS Spoofing Attacks," explains how to fool GPS sensors like those in drones by mimicking GPS signals. There's no way to know, Peshin said, if this report ...
Is the universe a hologram?

Summary: The 'holographic principle,' the idea that a universe with gravity can be described by a quantum field theory in fewer dimensions, has been used for years as a mathematical tool in strange curved spaces. New results suggest that the holographic principle also holds in flat spaces. Our own universe could in fact be two dimensional and only appear three dimensional -- just like a hologram. Credit: At first glance, there is not the slightest doubt: to us, the universe looks three dimensional. But one of the most fruitful theories of theoretical physics in the last two decades is challenging this assumption. The "holographic principle" asserts that a mathematical ...

The FBI faked an entire field of forensic science. For more stories like this, like Slate on Facebook and follow us on Twitter. The Washington Post published a story so horrifying this weekend that it would stop your breath: “The Justice Department and FBI have formally acknowledged that nearly every examiner in an elite FBI forensic unit gave flawed testimony in almost all trials in which they offered evidence against criminal defendants over more than a two-decade period before 2000.” What went wrong? The Post continues: “Of 28 examiners with the FBI Laboratory’s microscopic hair comparison unit, 26 overstated forensic matches in ways that favored prosecutors in ...

Pravda.Ru Purpose of the experiment with attaching the head to new body is immortality-transplantologist. 55014.jpeg The Italian transplantologist who has claimed that he could transplant a man's head onto a donor's body has said that he could do much of the procedure in less than an hour. The procedure - which Canavero has admitted is just a first step towards his ultimate aim of creating immortality - will see a man's head removed and placed on a donor's body. That will see the man's head get cooled down - as it is when doctors operate on some parts of the brain - and switched onto the different body. Doctors will then have a few minutes to attach the blood ...
Did NASA Mistakenly Create a Warp Field?

Space geeks are freaking out because NASA may have accidentally discovered a warp field, an avenue down which spaceships can travel faster than the speed of light – something that, to date, has only existed in science fiction. Warp drive was long the stuff of Star Trek fantasy – “Warp speed, Mr. Sulu,” is the command often given by James Kirk, captain of the fictional Starship Enterprise. But in the 1990s, physicist Miguel Alcubierre proposed the idea of a wave that would cause the space ahead of a spacecraft to contract, while the space behind it expands. This distortion would create a warp bubble, in which a ship would travel while itself remaining stationary. The ...

Study: Global Warming Has Slowed But Could Heat Up Again Friday, 24 Apr 2015 10:18 AM By Andrea Billups A study led by Duke University of 1,000 years of temperature records has shown that global warming is not occurring as fast as some have suggested, the U.K.'s Daily Mail reported. "Based on our analysis, a middle-of-the-road warming scenario is more likely, at least for now," Patrick Brown, a doctoral student in climatology at Duke University, said of the analysis of the research. "But this could change." The analysis, which compared results with scenarios suggested by the Intergovernmental Panel on Climate Change, and relied on observed data, not climate ...
Large reservoir of hot, partly molten rock discovered beneath Yellowstone

A big reservoir of hot, partly molten rock has been discovered beneath the famed Yellowstone National Park in the United States, but researchers said Thursday there is no added risk of volcanic eruption. The findings in the journal Science show for the first time that the amount of magma beneath the surface is far bigger than previously thought. The reservoir lies 12 to 28 miles (19 to 45 kilometers) beneath the Yellowstone supervolcano and is more than four times bigger than the magma chamber that is already known to exist. “For the first time, we have imaged the continuous volcanic plumbing system under Yellowstone,” said co-author Hsin-Hua Huang, a post-doctoral researcher ...

The early Greeks had a better, more basic understanding of weather and climate than the people involved in the Intergovernmental Panel on Climate Change (IPCC). Indeed, the word climate derives from the Greek word klima, meaning inclination, referring to the climate conditions created by the angle of the Sun. They paid great attention to the wind, realizing its role in creating local, regional and seasonal conditions. They even erected a tower to the wind in Athens (Figure 1) with sculptures representing each major compass direction. Click for Full Text!

Neuroanatomical Correlates of the Income-Achievement Gap www.amren.com/news/2015/0...correlates-of-the-income- achievement-gap/ In the United States, the difference in academic achievement between higher- and lower-income students (i.e., the income-achievement gap) is substantial and growing. In the research reported here, we investigated neuroanatomical correlates of this gap in adolescents (N = 58) in whom academic achievement was measured by statewide standardized testing. Cortical gray-matter volume was significantly greater in students from higher-income backgrounds (n = 35) than in students from lower-income backgrounds (n = 23), but cortical white-matter volume and total cortical ...

Sputnik... The only thing more terrifying than a US military drone? One that doesn’t need to stop for gas. The Navy’s bat-wing drone, the first capable of launching from an aircraft carrier, can now also refuel in midair. The X-47B test UAV has completed the first-ever autonomous aerial refueling. Developed by Northrop Grumman, the drone received over 4,000 pounds of fuel from a tanker jet just off the coast of Virginia. "What we accomplished today demonstrates a significant, groundbreaking step forward for the Navy," Captain Beau Duarte, program manager for the Navy’s unmanned carrier aviation program, said in a statement. "The ability to autonomously ...

A ‘dirty bomb’ of pseudo-science wrapped up nearly 268 cases – perhaps hundreds more. Now begins the ‘herculean effort to right the wrongs’ In 2013, the FBI admitted that the foundations of what it called ‘hair comparison evidence’ were scientifically invalid George Perrot has spent almost 30 years in prison thanks to a single hair. It was discovered by an FBI agent on the bedsheet of a 78-year-old woman who had been raped by a burglar in her home in Springfield, Massachusetts, in 1985. Perrot, then 17, was put on trial, despite the absence of physical evidence tying him to the crime scene. There was no semen. There was no blood. And so there was no way ...

NBC NEWS During an hours-long national call-in program, Russian President Vladimir Putin said his country is planning to create its own orbital space station by 2023, just as the operational life of the current International Space Station is due to wind down. It was only the latest in a string of contradictory statements about how Russia sees life in space after the ISS. Putin said a national space station was an economic necessity. "We use the ISS actively for science and the economy, but from the ISS only 5 percent of the area of Russia can be seen," he said Thursday. "From a national station, of course, we will be able to see the whole territory of our vast country." ...

ScienceDaily... Genetically engineered fibers of the protein spidroin, which is the construction material for spider webs, has proven to be a perfect substrate for cultivating heart tissue cells, MIPT researchers found. They discuss their findings in an article that has recently come out in the journal PLOS ONE. The cultivation of organs and tissues from a patient's cells is the bleeding edge of medical research -- regenerative methods can solve the problem of transplant rejection. However,it's quite a challenge to find a suitable frame, or substrate, to grow cells on. The material should be non-toxic and elastic andshould not be rejected by the body or impede cell growth.

They believe people should be punished for being climate skeptics Adam Weinstein, of the Gawker, has added his voice to the growing list of greens, who demand a brutal authoritarian response to the vexing problem of people who have a different opinion. According to Weinstein; Man-made climate change happens. Man-made climate change kills a lot of people. It’s going to kill a lot more. We have laws on the books to punish anyone whose lies contribute to people’s deaths. It’s time to punish the climate-change liars. This is an argument that’s just being discussed seriously in some circles. It was laid out earlier this month, with all the appropriate caveats, by Lawrence ...

Summary: Mars has distinct polar ice caps, but Mars also has belts of glaciers at its central latitudes in both the southern and northern hemispheres. A thick layer of dust covers the glaciers, so they appear as surface of the ground, but radar measurements show that underneath the dust there are glaciers composed of frozen water. New studies have now calculated the size of the glaciers and thus the amount of water in the glaciers. Click for Full Text!
