Sputnik... A mobile phone microscope capable of detecting and quantifying parasites in a drop of blood has been developed by a group of scientists led by a team at the University of California, Berkeley, media reports said. "We previously showed that mobile phones can be used for microscopy, but this is the first device that combines the imaging technology with hardware and software automation to create a complete diagnostic solution," according to Daniel Fletcher of UC Berkeley. He explained that "with one touch of the screen, the device moves the sample, captures video and automatically analyses the images." The CellScope system includes a modified smartphone with ...

Musk Pushes Utility Industry One Step Closer to Doomsday Wednesday, 06 May 2015 07:00 AM By Patrick Watson No one likes utility companies. Most are monopolies and it shows in their customer service. You pay a lot and you get whatever they feel like giving you. I wrote back in February (see Clock Ticking Down for Electric Utilities) that serial entrepreneur Elon Musk had a plan to change all this. Last week, he unveiled the last missing link. In theory, solar energy is an ideal way to provide electricity for homes and businesses. Prices for rooftop panels dropped sharply the last few years. Amortized over a decade or two, the price is considerably lower than what your regulated ...
Is having a loving family an unfair advantage?

Plato famously wanted to abolish the family and put children into care of the state. Some still think the traditional family has a lot to answer for, but some plausible arguments remain in favour of it. Joe Gelonesi meets a philosopher with a rescue plan very much in tune with the times. So many disputes in our liberal democratic society hinge on the tension between inequality and fairness: between groups, between sexes, between individuals, and increasingly between families. The power of the family to tilt equality hasn’t gone unnoticed, and academics and public commentators have been blowing the whistle for some time. Now, philosophers Adam Swift and Harry Brighouse have felt ...

ScienceAlert... NASA engineers have successfully flown an unmanned aircraft that can takeoff, land and hover like a helicopter, and fly horizontally like a fixed-wing plane. The team's battery-powered aircraft uses a system of 10 engines on tilted wings to achieve vertical takeoff and landing. During recent test flights near Langley Research Centre in the US, the prototype - known as Greased Lightning, or GL-10 - successfully transitioned to horizontal flight. You can watch the flight test in the above video. "During the flight tests we successfully transitioned from hover to wing-borne flight like a conventional airplane then back to hover again. So far we have done this on ...

ScienceDaily... Are patents primarily a rearrangement of words and ideas? Credit: © Feng Yu / Fotolia Most new patents are combinations of existing ideas and pretty much always have been, even as the stream of fundamentally new core technologies has slowed, according to a new paper in the Journal of the Royal Society Interface by Santa Fe Institute researchers Hyejin Youn, Luis Bettencourt, Jose Lobo, and Deborah Strumsky. Youn and colleagues reached those conclusions sifting through the records of the United States Patent and Trademark Office. Dating back to 1790, the records feature an elaborate system of technology codes -- a vocabulary of sorts, in which any new invention is a ...

Want... China is leading the global race in the development of metamaterials, spearheading a new trend that is revolutionizing technology in fields ranging from telecommunications to aerospace, reports the overseas edition of the Communist Party mouthpiece People's Daily. Metamaterials are defined as materials engineered to have properties that have not yet been found in nature. They are made from complex assemblies of multiple elements fashioned from conventional materials and derive their properties from their designed structure — such as shape, geometry, size, orientation and arrangement — as opposed to the properties of the base materials. Appropriately designed ...

Sputnik... Scientists at Johnson Space Center, successfully tested the EM drive in a vacuum, yielding results that "defy classical physics” expectations that such a closed (microwave) cavity should be unusable for space propulsion because of the law of conservation of momentum," NASA announced Wednesday. The idea that the NASA Eagleworks propulsion research group has been working on — as it was proposed in 2001 — is that such a device, operating in such a cavity would convert electrical energy directly into motion (thrust) without requiring fuel. — Aaron Linde (@aaronlinde) April 30, 2015 Scientists had generally thought propellant expulsion was needed to ...

Beyond genes: Are centrioles carriers of biological information?
Post Date: 2015-05-02 03:12:42 by Tatarewicz
0 Comments
ScienceDaily... EPFL scientists discover that certain cell structures, the centrioles, could act as information carriers throughout cell generations. The discovery raises the possibility that transmission of biological information could involve more than just genes. Centrioles are barrel-shaped structures inside cells, made up of multiple proteins. They are currently the focus of much research, since mutations in the proteins that make them up can cause a broad range of diseases, including developmental abnormalities, respiratory conditions, male sterility and cancer. Publishing in the Nature journal Cell Research, EPFL scientists show that the original centrioles of a fertilized egg, ...
New origin theory for cells that gave rise to vertebrates

ScienceDaily... The vivid pigmentation of zebras, the massive jaws of sharks, the fight or flight instinct and the diverse beaks of Darwin's finches. These and other remarkable features of the world's vertebrates stem from a small group of powerful cells, called neural crest cells, but little is known about their origin. Now Northwestern University scientists propose a new model for how neural crest cells, and thus vertebrates, arose more than 500 million years ago. The researchers report that, unlike other early embryonic cells that have their potential progressively restricted as an embryo develops, neural crest cells retain the molecular underpinnings that control pluripotency ...

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 ...
Origin of life: Chemistry of seabed's hot vents could explain emergence of life

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 ...

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 ...
