There are at least 12 kinds of rainbows, a new study reveals, and some skip a color or two. Since the 1950s, rainbow classification has been based on the size of the raindrops that create them. The bigger the drops, the more vivid the colors. Another attempt organized them by the height of the sun Read more about Some Rainbows Don’t Have Every Color of the Rainbow: there are 12 types[…]
The plan is to implant up to 11 small tiles, each loaded with 43 electrodes, into areas of the brain that deal with vision. When these areas are stimulated, people report seeing flashes of light. Lowery believes that each electrode could create a dot of light that is similar to seeing one pixel. In total, Read more about Bionic eye will send images direct to the brain to restore sight via 500 pixel “display”[…]
The Chinese scientist behind the world’s biggest cloning factory has technology advanced enough to replicate humans, he told AFP, and is only holding off for fear of the public reaction. Boyalife Group and its partners are building the giant plant in the northern Chinese port of Tianjin, where it is due to go into production Read more about China ‘clone factory’ scientist eyes human replication[…]
Turns out that companies have been writing information that makes US citizens not believe in climate change science. “The comprehensive data include all individual and organizational actors in the climate change countermovement (164 organizations), as well as all written and verbal texts produced by this network between 1993–2013 (40,785 texts, more than 39 million words). Read more about Corporate funding and ideological polarization about climate change[…]
As described in a paper posted online and submitted to Physical Review Letters (PRL), researchers from NIST and several other institutions created pairs of identical light particles, or photons, and sent them to two different locations to be measured. Researchers showed the measured results not only were correlated, but also—by eliminating all other known options—that Read more about NIST team proves ‘spooky action at a distance’ is really real[…]
The most surprising finding? “Our e-skin picked up sound better than the mic on a smartphone.” Ko says that exactly how the pressure, texture, temperature, and acoustic signals will be transmitted into the brain is his next challenge. Source: New artificial fingerprints feel texture, hear sound
The researchers observed the atoms under a microscope by illuminating them with a separate imaging laser. A light microscope can’t see individual atoms, but the imaging laser causes them to fluoresce, and the microscope captured the flashes of light. When the imaging laser was off, or turned on only dimly, the atoms tunneled freely. But Read more about ‘Zeno effect’ verified, Heisenberg uncertainty principle controlled: Atoms won’t move while you watch[…]
Researchers at the University of Groningen in the Netherlands have created a process that can manufacture 3D-printed teeth and braces which are actually good for your other teeth, and dental health in general. Source: 3D-printed teeth can kill 99% of bacteria
A 28-year-old who has been paralyzed for more than a decade as a result of a spinal cord injury has become the first person to be able to “feel” physical sensations through a prosthetic hand directly connected to his brain, and even identify which mechanical finger is being gently touched.The advance, made possible by sophisticated Read more about Prosthetic hands can now feel[…]
Yet again a major study looks at reproducing results (in this case only in psychological studies) and finds that the strength of the results is much lower than published. Expect this to happen for economics, political science, etc as well. Reproducibility is a defining feature of science, but the extent to which it characterizes current Read more about Estimating the reproducibility of psychological science – not doing too well…[…]
Well it kind of looks that way – when you train their network to recognise stuff it can add items to pictures. Source: Research Blog: Inceptionism: Going Deeper into Neural Networks
Scientists Have Made a Möbius Strip Out of Light for the First Time.
Scientists have discovered an antibiotic capable of fighting infections that kill hundreds of thousands of people each year, a breakthrough that could lead to the field’s first major new drug in more than a quarter-century.The experimental drug, which was isolated from a sample of New England dirt, is called teixobactin. It hasn’t yet been tested Read more about Antibiotic Pulled From Dirt Ends 25-Year Drug Drought – Bloomberg[…]
Scientists at the University of B.C. searching for ways to slow the deterioration of blood vessels may have stumbled on to the key to youthful skin. While exploring the effects of the protein-degrading enzyme Granzyme B on blood vessels during heart attacks, professor David Granville couldn’t help noticing that mice engineered to lack the enzyme Read more about Rresearchers may have stumbled upon the secret to youthful skin[…]
Users of Watson Analytics feed in their own raw data, say, in the form of a spreadsheet, which the service then crunches with its own statistical analysis to highlight associations between different variables. It saves execs from needing to know how to write their own scripts or understand statistics in order to derive meaning from Read more about IBM’s Watson Analytics enters public beta | ZDNet[…]

We show that non-ionizing, low-power laser (LPL) treatment can instead be used as a minimally invasive tool to activate an endogenous latent growth factor complex, transforming growth factor–β1 (TGF-β1), that subsequently differentiates host stem cells to promote tissue regeneration. LPL treatment induced reactive oxygen species (ROS) in a dose-dependent manner, which, in turn, activated latent Read more about Regrow your teeth with lasers![…]

Doctors in UPMC Presbyterian Hospital in Pittsburgh, Pennsylvania are now waiting for a patient to show up with a gaping chest wound, who’s lost around 50% of his / her blood so they can replace the entire blood supply with a cold saline solution, which rapidly cools the body and stops almost all cellular activity. Read more about Gunshot victims to be suspended by replacing their blood[…]

After years of research and hours of gruelling surgery, scientists have successfully attached sensors from a prosthetic hand to human nerve tissue to allow the device to give its wearer a sense of touch. via First man/machine nerve grafts restore amputee's sense of touch • The Register.
In the PNNL process, a slurry of wet algae is pumped into the front end of a chemical reactor. Once the system is up and running, out comes crude oil in less than an hour, along with water and a byproduct stream of material containing phosphorus that can be recycled to grow more algae. http://phys.org/news/2013-12-algae-crude-oil-million-year-natural.html
A team of physicists has provided some of the clearest evidence yet that our Universe could be just one big projection. In 1997, theoretical physicist Juan Maldacena proposed1 that an audacious model of the Universe in which gravity arises from infinitesimally thin, vibrating strings could be reinterpreted in terms of well-established physics. The mathematically intricate Read more about Simulations back up theory that Universe is a hologram – and it seems that wormholes can be created using entanglement[…]
Experiments showed that a traumatic event could affect the DNA in sperm and alter the brains and behaviour of subsequent generations. A Nature Neuroscience study shows mice trained to avoid a smell passed their aversion on to their “grandchildren”. The animals were trained to fear a smell similar to cherry blossom. The team at the Read more about evidence of transgenerational epigenetic inheritance: ‘Memories’ pass between generations[…]
Using inexpensive materials configured and tuned to capture microwave signals, researchers at Duke University’s Pratt School of Engineering have designed a power-harvesting device with efficiency similar to that of modern solar panels. The device wirelessly converts the microwave signal to direct current voltage capable of recharging a cell phone battery or other small electronic device, Read more about Wireless Device Converts “Lost” Energy such as WiFi signals into Electric Power[…]
