We’ve seen interactive rings that receive alerts from your smartphone and even rings that will give you the current time in a unique way, but a new ring leapfrogs the rest by acting as a full-on control mechanism.
On its exterior, Logbar’s Ring device looks like nothing more than a silver ring, but packed inside the device are electronics that allow it to recognize your finger gestures and control any number of devices.
Logbar CEO Takuro Yoshida gave a detailed demonstration of the silver interactive device last year in San Francisco, and now Ring is available for purchase through a Kickstarter campaign.
Some people claim that they have experienced out-of-body experiences—aka “astral trips”—floating outside of their bodies and watching themselves from the outside. A team of scientists found someone who says she can do this at will and put her into a brain scanner. What they discovered was surprisingly strange.
Andra M. Smith and Claude Messierwere from the University of Ottawa described this subject’s ability in their paper, published in Frontiers of Human Neuroscience:
She was able to see herself rotating in the air above her body, lying flat, and rolling along with the horizontal plane. She reported sometimes watching herself move from above but remained aware of her unmoving “real” body. The participant reported no particular emotions linked to the experience.

Behold the mighty mushroom. Neither plant nor animal, the mysterious fungus is a class, or kingdom, of its own, and has fascinated cultures around the world for centuries. But while they do make a tasty omelette filling, does the real magic of mushrooms lie not in their flavour, but in their potential to combat one of our biggest killers – cancer?
The ancient Egyptians believed eating mushrooms brought long life. While their scientific method was perhaps not entirely sound, modern scientists investigating the medicinal properties of the organism are beginning to produce some fascinating results. There are thousands of species of mushroom growing in the wild, but most studies have focused on three main varieties – reishi, maitake and shiitake.
Reishi, otherwise known as ganoderma, has been used in Chinese medicine for 2,000 years and numerous studies have investigated its much-vaunted anti-cancer and immune-boosting properties. In a paper published last year in the US’s Proceedings of the National Academy of Sciences (PNAS) journal, a team of scientists linked its use to cancer-cell death. The team, from the Taiwanese research centre Academia Sinica, found that F3 polysaccharides, a type of carbohydrate molecule found in reishi mushrooms, can induce antibodies to recognise and kill antigens associated with tumours or cancer cells.
This is amazing news: NASA is sending a mission to Europa! If everything goes well, a robotic submarine may be landing on Jupiter’s moon—the world that scientists believe is the most likely to contain life in the Solar System—by 2030, a real space odyssey. This has the potential to change the world.
“Attempt no landings there,” the aliens said at the end of 2010, a warning that Adam Steltzner—the guy who spent nine years of his life putting the rover Curiosity on Mars in the most spectacular NASA mission since the Apollo program—doesn’t care about. This is his dream mission and the dream mission of every space scientists now at NASA, as he said back in August 2012, after Curiosity’s successful landing on Mars.
Adam: The site in the solar system that we believe that is the most likely to contain life today is Europa. I want to lead a team to go under the ice, into the ocean of the moon Europa.
Reporter: Get a submarine up there.
Phlebotomy. Even the word sounds archaic—and that’s nothing compared to the slow, expensive, and inefficient reality of drawing blood and having it tested. As a college sophomore, Elizabeth Holmes envisioned a way to reinvent old-fashioned phlebotomy and, in the process, usher in an era of comprehensive superfast diagnosis and preventive medicine.
That was a decade ago. Holmes, now 30, dropped out of Stanford and founded a company called Theranos with her tuition money. Last fall it finally introduced its radical blood-testing service in a Walgreens pharmacy near company headquarters in Palo Alto, California. (The plan is to roll out testing centers nationwide.) Instead of vials of blood—one for every test needed—Theranos requires only a pinprick and a drop of blood. With that they can perform hundreds of tests, from standard cholesterol checks to sophisticated genetic analyses. The results are faster, more accurate, and far cheaper than conventional methods.
The implications are mind-blowing. With inexpensive and easy access to the information running through their veins, people will have an unprecedented window on their own health. And a new generation of diagnostic tests could allow them to head off serious afflictions from cancer to diabetes to heart disease.
In what seems like a plot straight out of a low-budget science-fiction film, scientists have revived a giant virus that was buried in Siberian ice for 30,000 years — and it is still infectious. Its targets, fortunately, are amoebae, but the researchers suggest that as Earth’s ice melts, this could trigger the return of other ancient viruses, with potential risks for human health.
The newly thawed virus is the biggest one ever found. At 1.5 micrometres long, it is comparable in size to a small bacterium. Evolutionary biologists Jean-Michel Claverie and Chantal Abergel, the husband-and-wife team at Aix-Marseille University in France who led the work, named it Pithovirus sibericum, inspired by the Greek word ‘pithos’ for the large container used by the ancient Greeks to store wine and food. “We’re French, so we had to put wine in the story,” says Claverie. The results are published in Proceedings of the National Academy of Sciences.
Claverie and Abergel have helped to discover other so-called giant viruses — including the first, called Mimivirus, in 2003, and two others, known as Pandoraviruses, last year. “Once again, this group has opened our eyes to the enormous diversity that exists in giant viruses,” says Curtis Suttle, a virologist at the University of British Columbia in Vancouver, Canada, who was not involved in the work.
Two years ago, Claverie and Abergel’s team learned that scientists in Russia had resurrected an ancient plant from fruits buried in 30,000-year-old Siberian permafrost. “If it was possible to revive a plant, I wondered if it was possible to revive a virus,” says Claverie. Using permafrost samples provided by the Russian team, they fished for giant viruses by using amoebae — the typical targets of these pathogens — as bait. The amoebae started dying, and the team found giant-virus particles inside them.
Under a microscope, Pithovirus appears as a thick-walled oval with an opening at one end, much like the Pandoraviruses. But despite their similar shapes, Abergel notes that “they are totally different viruses”.
Harvard bioengineers say they have taken a big step toward using 3-D printers to make living tissue. They’ve made a machine with multiple printer heads that each extrudes a different biological building block to make complex tissue and blood vessels.
Their work represents a significant advance toward producing living medical models upon which drugs could be tested for safety and effectiveness.
It also advances the ball in the direction of an even bigger goal. Such a machine and the techniques being refined by researchers offer a glimpse of the early steps in a sci-fi healthcare scenario: One day surgeons might feed detailed CT scans of human body parts into a 3-D printer, manipulate them with design software, and produce healthy replacements for diseased or injured tissues or organs.
“This is the foundational step toward creating 3-D living tissue,” said Jennifer Lewis, senior author of the study published Feb. 18 in the journal Advanced Materials, in a university release.
An 82-foot telescope boasting ten times the resolution of the Hubble Space Telescope has successfully passed design reviews and is ready to be constructed.
The Giant Magellan Telescope will use a light-collecting mirror surface more than six times the area of current instruments to hunt for distant, potentially habitable planets and let astronomers time travel back to a billion years after the Big Bang.
Huge improvements in resolution are expected from the telescope’s adaptive optics system, which will flex secondary mirrors to compensate for atmospheric turbulence that normally distorts starlight.
An international consortium managing the project has chosen a remote Andean mountaintop in Chile to build the telescope. Technicians have already begun fabricating three of the device’s seven primary mirrors at a lab in Arizona.
“I am delighted with the very positive results of the design and the cost reviews,” said Wendy Freedman, director of the Carnegie Institution for Science observatories and chair of the board overseeing the project, in a statement. “Along with the successful casting of the first three 8.4-meter primary mirrors and the leveling of the mountaintop in Chile, each step brings us closer to construction.”
Backers of the telescope, which is expected to begin operating in a decade, say it will usher in a revolution in human knowledge about the universe.
Move over, copper wires. The next generation of electricity cables may well be made from lettuce, based on the innovation of a U.K. researcher. The advance could pave the way to biological computers and bio-robots of the future.
Computer scientist Andrew Adamatzky of the University of West England did a series of tests with four-day-old lettuce seedlings. To create bio-wires, he bridged two electrodes made from conductive aluminum foil with a seedling that was placed onto the electrodes in drops of distilled water.
Next, he applied electrical potential between electrodes ranging from 2 to 12 volts, and calculated the seedling’s so-called potential transfer function that shows output potential as a fraction of input potential — the amount of energy produced relative to energy put in.
He found that resistance of the seedling repetitively changed with time, or oscillated. He determined that, roughly, the output potential was 1.5-2 V less than the input potential, “so by applying 12 V potential we get 10 V output potential,” he said.
AN award-winning professor from the University has followed in the footsteps of Indiana Jones by cracking the code of a 600 year old manuscript, deemed as ‘the most mysterious’ document in the world. Stephen Bax, Professor of Applied Linguistics, has just become the first professional linguist to crack the code of the Voynich manuscript using an analytical approach. The world-renowned manuscript is full of illustrations of exotic plants, stars, and mysterious human figures, as well as many pages written in an unknown text.
Up until now the 15th century cryptic work has baffled scholars, cryptographers and codebreakers who have failed to read a single letter of the script or any word of the text. Over time it has attained an infamous reputation, even featuring in the latest hit computer game Assassin’s Creed, as well as in the Indiana Jones novels, when Indiana decoded the Voynich and used it to find the ‘Philosopher’s Stone’. However in reality no one has come close to revealing the Voynich’s true messages.
Many grand theories have been proposed. Some suggest it was the work of Leonardo da Vinci as a boy, or secret Cathars, or the lost tribe of Israel, or most recently Aztecs … some have even proclaimed it was done by aliens! Professor Bax however has begun to unlock the mystery meanings of the Voynich manuscript using his wide knowledge of mediaeval manuscripts and his familiarity with Semitic languages such as Arabic. Using careful linguistic analysis he is working on the script letter by letter.
In what could prove to be a major breakthrough in quantum memory storage and information processing, German researchers have frozen the fastest thing in the universe: light. And they did so for a record-breaking one minute.
It sounds weird and it is. The reason for wanting to hold light in its place (aside from the sheer awesomeness of it) is to ensure that it retains its quantum coherence properties (i.e. its information state), thus making it possible to build light-based quantum memory. And the longer that light can be held, the better as far as computation is concerned. Accordingly, it could allow for more secure quantum communications over longer distances.

After 26 years of workdays spent watching bacteria multiply, Richard Lenski has learned a thing or two.
He’s learned that naturalist Charles Darwin was wrong about some things. For one, evolution doesn’t always occur in steps so slow and steady that changes can’t be observed.
Lenski also learned that a laboratory freezer can function as a time machine.
A professor at Michigan State University, Lenski has watched E. coli bacteria multiply through 59,000 generations, a span that has allowed him to observe evolution in real time. Since his Long-Term Experimental Evolution Project began in 1988, the bacteria have doubled in size, begun to mutate more quickly, and become more efficient at using the glucose in the solution where they’re grown.
More strikingly, however, he found that one of the 12 bacterial lines he has maintained has developed into what he believes is a new species, able to use a compound in the solution called citrate—a derivative of citric acid, like that found in some fruit—for food.
Some people recall a dream every morning, whereas others rarely recall one. A team led by Perrine Ruby, an Inserm Research Fellow at the Lyon Neuroscience Research Center, has studied the brain activity of these two types of dreamers in order to understand the differences between them. In a study published in the journal Neuropsychopharmacology, the researchers show that the temporo-parietal junction, an information-processing hub in the brain, is more active in high dream recallers. Increased activity in this brain region might facilitate attention orienting toward external stimuli and promote intrasleep wakefulness, thereby facilitating the encoding of dreams in memory.
The reason for dreaming is still a mystery for the researchers who study the difference between “high dream recallers,” who recall dreams regularly, and “low dream recallers,” who recall dreams rarely. In January 2013, the team led by Perrine Ruby, Inserm researcher at the Lyon Neuroscience Research Center, made the following two observations: “high dream recallers” have twice as many time of wakefulness during sleep as “low dream recallers” and their brains are more reactive to auditory stimuli during sleep and wakefulness. This increased brain reactivity may promote awakenings during the night, and may thus facilitate memorisation of dreams during brief periods of wakefulness.

but by making the darkness conscious.”
