Science X Newsletter Week 39

Dear Reader ,

Here is your customized Science X Newsletter for week 39:

	Iron nanoparticles make immune cells attack cancer Stanford researchers accidentally discovered that iron nanoparticles invented for anemia treatment have another use: triggering the immune system's ability to destroy tumor cells.
	Quantum computing advances with control of entanglement When the quantum computer was imagined 30 years ago, it was revered for its potential to quickly and accurately complete practical tasks often considered impossible for mere humans and for conventional computers. But, there was one big catch: Tiny-scale quantum effects fall apart too easily to be practical for reliably powering computers.
	Scientists find evidence for alternate theory of how life arose A new study led by scientists at The Scripps Research Institute (TSRI) offers a twist on a popular theory for how life on Earth began about four billion years ago.
	Making space rocket fuel from water could drive a power revolution on Earth Researchers led by NASA's former chief technologist are hoping to launch a satellite carrying water as the source of its fuel. The team from Cornell University, guided by Mason Peck, want their device to become the first shoebox-sized "CubeSat" to orbit the moon, while demonstrating the potential of water as a source of spacecraft fuel. It's a safe, stable substance that's relatively common even in space, but could also find greater use here on Earth as we search for alternatives to fossil fuels.
	Reservoirs play substantial role in global warming Washington State University researchers say the world's reservoirs are an underappreciated source of greenhouse gases, producing the equivalent of roughly 1 gigaton of carbon dioxide a year, or 1.3 percent of all greenhouse gases produced by humans.
	World's deepest underwater cave found in the Czech Republic (Update) A team of explorers say they've discovered that a cave in the eastern Czech Republic is the world's deepest flooded fissure, going at least 404 meters (1,325 feet) deep.
	Quantum computing a step closer to reality Physicists at the Australian National University (ANU) have brought quantum computing a step closer to reality by stopping light in a new experiment.
	Giant dinosaur footprint discovered in Mongolia desert One of the biggest dinosaur footprints ever recorded has been unearthed in the Gobi Desert, researchers said Friday, offering a fresh clue about the giant creatures that roamed the earth millions of years ago.
	Room-temp superconductors could be possible Superconductors are the holy grail of energy efficiency. These mind-boggling materials allow electric current to flow freely without resistance. But that generally only happens at temperatures within a few degrees of absolute zero (minus 459 degrees Fahrenheit), making them difficult to deploy today. However, if we're able to harness the powers of superconductivity at room temperature, we could transform how energy is produced, stored, distributed and used around the globe.
	First quantum photonic circuit with an electrically driven light source Whether for use in safe data encryption, ultrafast calculation of huge data volumes or so-called quantum simulation of highly complex systems: Optical quantum computers are a source of hope for tomorrow's computer technology. For the first time, scientists now have succeeded in placing a complete quantum optical structure on a chip, as outlined Nature Photonics. This fulfills one condition for the use of photonic circuits in optical quantum computers.
	Rubidium pushes perovskite solar cells to 21.6 percent efficiency EPFL scientists have stabilized perovskite solar cells by integrating rubidium into them. The innovation pushes power-conversion efficiency to 21.6%, ushering a new generation of perovskite solar cells.
	Scientists investigate unidentified radio sources (Phys.org)—A team of researchers led by Andrea Maselli of the Institute of Space Astrophysics and Cosmic Physics of Palermo, Italy, has conducted an observational campaign of a group of unassociated radio sources with NASA's Swift space observatory. The observations were aimed at revealing the true nature of these so far unidentified sources. The results were published Sept. 23 in a paper on arXiv.org.
	Game theory research reveals fragility of common resources New research in game theory shows that people are naturally predisposed to over-use "common-pool resources" such as transportation systems and fisheries even if it risks failure of the system, to the detriment of society as a whole.
	Scientists visualise quantum behaviour of hot electrons for first time Scientists have, for the first time, identified a method of visualising the quantum behaviour of electrons on a surface. The findings present a promising step forward towards being able to manipulate and control the behaviour of high energy, or 'hot', electrons.
	Elon Musk envisions 'fun' but dangerous trips to Mars (Update 4) SpaceX chief Elon Musk unveiled on Tuesday ambitious plans to establish a Mars colony by sending 100 humans at a time on massive spacecraft, possibly costing as low as $100,000 per person.
	Biologist comments on a startling new finding in climate change research The steady march of global warming over the past century has led to the thawing of permafrost—a layer of subsurface soil in the Arctic that usually remains frozen year-round. While that's troubling for local ecosystems, it could have disastrous global impacts as well. As this permafrost melts, it sets off a biochemical chain reaction in the soil that could dramatically increase the emission of greenhouse gases into the atmosphere, accelerating further climate change. San Diego State University biologist Donatella Zona wrote about this issue in a commentary article this week in the journal Nature.
	Parkinson's disease protection may begin in the gut: Intestinal cells' immune response protects vital neurons Your gut may play a pivotal role in preventing the onset of Parkinson's disease. And the reason may be its knack for sleuthing.
	Photons do the twist, and scientists can now measure it Researchers in the University of Minnesota's College of Science and Engineering have measured the twisting force, or torque, generated by light on a silicon chip. Their work holds promise for applications such as miniaturized gyroscopes and torsional sensors to measure magnetic field, which can have significant industrial and consumer impact.
	Creating antimatter via lasers? Dramatic advances in laser technologies are enabling novel studies to explore laser-matter interactions at ultrahigh intensity. By focusing high-power laser pulses, electric fields (of orders of magnitude greater than found within atoms) are routinely produced and soon may be sufficiently intense to create matter from light.
	A rule of chemistry suppressed: Promising new ways to look inside cells, make LEDs Glow-in-the-dark stickers, weird deep-sea fish, LED lightbulbs—all have forms of luminescence. In other words, instead of just reflecting light, they make their own.
