Quantum batteries are theoretically awesome, practically non-existent

Today’s dose of overly ambitious tech research comes from the physics lab over at the University of Illinois at Urbana-Champaign, in a proposal titled “Digital quantum batteries: Energy and information storage in nano vacuum tube arrays.” It’s like a who’s who of undelivered promises got together and united to form one giant and impossible dream, but it’s one we’d prefer to believe in regardless. Aiming to improve battery performance by “orders of magnitude,” the project’s fundamental premise is that when capacitors — and we’re talking billions of them — are taken to a small enough scale and packed to within 10nm of one another, quantum effects act to prevent energy loss. The projected result is a wonderful world of rapid recharges and storage of up to ten times the energy current lithium-ion packs can hold, as well as the potential for data retention. The only problem? It would take a year just to build a prototype, meaning we can expect market availability somewhere between a score from now and just prior to the underworld morphing into an ice rink.

Watch a Volcano Erupt Deep Beneath the Ocean

When an undersea volcano erupted this past May near Samoa, researchers captured video of the blast. Now they’ve released the footage, giving the rest of the world its first look at the deepest underwater eruption ever caught on film.

The West Mata undersea volcano, located 200 kilometers from Samoa, erupted in May. Researchers with the National Oceanic and Atmospheric Administration sent the remotely operated underwater vehicle Jason to record the explosive action. In addition to tossing up lava and chunks of rock, West Mata also released a significant amount of sulfuric acid into the water, rendering its acidity somewhere between battery acid and stomach acid. The research team collected various samples and is analyzing them and the footage to better understand these deep sea eruptions and the life that exists around these deep underwater volcanoes. Meanwhile, we get a spectacular view of the eruption itself.

Mars Phoenix Lander May Become Undead

NASA_Phoenix_Mars_Lander.jpg

NASA’s Phoenix Mars lander, which was originally created from the ashes of a failed Mars mission that never got off the ground, could soon itself rise from the dead, Space.com reports.

Scientists may have figured out how to establish contact with the electronic systems of the now-dormant Phoenix. The craft had essentially frozen solid near the end of 2008 during the Mars winter season, which is normally good for an average temperature of minus 195 degrees Fahrenheit.

It turns out Lockheed Martin Space Systems, which built the lander, included a secret ninja Lazarus Mode that could re-energize Phoenix. If scientists can re-establish contact, and this hidden mode actually works, the only obstacle remaining would be whether the solar panels had survived.

If NASA manages to bring Phoenix back to life, they could salvage several important systems, including the various cameras, an analyzer that measures atmospheric gases, and a complete stationary weather station. Here’s hoping.

Ten Science Stories That Changed Our Decade

There is no doubt that science has become more like science fiction in the past decade, with amazing innovations and discoveries that increased our understanding of the universe. We list ten of the biggest science stories from the past decade.

This was the decade of the first face transplant, the first extinct species brought back from the dead, and printable human tissue; a decade that brought us closer to synthetic life forms and the invisibility cloak. But we’ve whittled it down to ten of the decade’s biggest science stories, with discoveries, advances, and topics that are sure to change our lives in the next ten years.

It’s Full of Planets: This was a big decade for planets, and not just because Pluto got a downgrade. In 2005, astronomers discovered Eris, a dwarf planet larger Pluto (as well as smaller dwarf planets Haumea and Makemake). Eris’ discovery prompted the International Astronomical Union to actually define the term planet, leading to Pluto’s demotion to dwarf planet. But the discovery of Eris after all this time suggests there is still a lot to learn about our solar system.

We also got our first direct look at exoplanets, worlds outside our solar system, thanks to the Hubble Telescope. In 2008, astronomers at the Keck and Gemini captured the first images of planets orbiting distant stars. And the planetary discoveries just keep getting more exciting; just this week, astronomers announced that they had observed a super-Earth that might be made largely of liquid water.

Water, Water Everywhere: The world watched on as the Phoenix Lander dug through the Martian terrain for signs of water on the Red Planet. In the summer of 2008, NASA announced it had found definitive proof of water ice on Mars. More recently, scientists discovered that large deposits of water ice exist beneath the planet’s surface. This fall, the moon became the center of our watery attention when astronomers found evidence of water throughout the moon’s surface. Although the supervillainous plot to bomb the moon didn’t seem as initially impressive as we had hoped, the probe did confirm researchers’ suspicions that the moon does, in fact, contain a significant amount of frozen water. These discoveries not only reveal more about our solar system, they indicate that, should humans try to colonize Mars or the moon, there will be resources to make survival a little easier.

Shaking Up the Human Family Tree: Humanity got a new great-great-grandmother (or perhaps she’s our great-great-great-aunt) in Ardi, a fossilized hominid skeleton found in Ethiopia. Granted, Ardipithecus ramidus was discovered in 1992, but it wasn’t until 2009 that she was revealed as a significant addition to our family tree. Although there’s technically no “missing link” because humans didn’t evolve from chimpanzees, Ardi is, so far, our closest link to chimps, and brings us closer to the common human-chimp ancestor than ever before. Analysis of Ardi’s skeleton and probably anatomy reveals just how unlike either chimps that common ancestor is bound to be. One of the Ardi researchers even quipped that when we find that common ancestor, it might look less like we evolved from a chimp-like creature and more like chimps evolved from creatures more like us.

The Book of Life Recorded: Our understanding of human genetics reached a new milestone with the mapping of the human genome. The Human Genome Project announced a rough draft of the human genome in 2000, followed by a more complete version in 2003; the sequence of the last chromosome was published in 2006. Though the genome hasn’t been 100 percent mapped, the Human Genome Project has completed its mapping goals. We still have to interpret the sequences we have recorded, but hopefully as we translate the book of our genetic lives, we will get a better understand of how our genes interact and improve our treatment of genetic diseases. Plus, the project has paved the way for sequencing other critters and plants, and, just this week, the lung cancer and melanoma genomes were sequenced.

Changing Your Genes: The promises of genetic engineering have really begun to bear fruit in the last few years, in ways far beyond Alba, the glowing transgenic bunny that grabbed headlines in 2000. In 1999, an 18-year-old with a, inherited liver disease died during a gene therapy trial, after suffering an unanticipated immune reaction to a viral vector. But in more recent years, gene therapy and genetic engineering have shown their promise. In 2000, scientists reported the first gene therapy success, having provided a patient with severe combine immunodeficiency (commonly known as “Bubble Boy” syndrome), though SCID gene therapy treatments were halted when patients developed leukemia. This year, gene therapy successfully treated children with a congenital form of blindness, giving them the ability to see for the first time in their lives. Meanwhile, genetic engineering experiments on animals have cured color blindness in monkeys, created super-strong monkeys, created drug-producing rats, and enabled animals to pass their altered genes to their offspring.

Stem Cells Grow Up: Embryonic stem cells have been a source of contention for years, but in 2007, Shinya Yamanaka helped sidestep that issue when he found a way to reprogram adult skin cells into induced pluripotent stem cells. Stem cells themselves have continued to aid important medical advances. In 2008, researchers generated motor neurons from elderly patients with ALS, an advance that could help researchers better understand the disease. A newly released study has suggested that a mini stem cell transplant could reverse sickle cell disease, and stem cell research has lead to advances in HIV research and the treatment of heart disease.

Climate Change Takes Center Stage: One of the biggest science stories of the decade has been less about scientific advances than about how the public responds to scientific research. Reports that the glaciers are melting faster than expected, a decade of record warmth, and Al Gore’s Nobel Prize have all been part of the conversation on climate change and to what extent humans are responsible.

Commercial Spacecrafts Prepare to Take Flight: Amidst NASA budget cuts, commercial spaceflight has come to the forefront. The Ansari X Prize, first offered in 1996 for the first private enterprise that could fly a three-passenger vehicle 100 kilopmeters into space twice in one week. In 2004, the prize was finally won by Mojave Aerospace Ventures’ SpaceShipOne. That same year, Virgin Galactic was founded to further space tourism. The company recently unveiled SpaceShipTwo, the first commercial spacecraft. 2004 also saw the certification of the Mojave Air and Space Port, the first licensed facility for horizontal launches of reusable spacecraft in the US. In anticipation of the spaceflight business, one company claims it’s readying a space hotel.

Our Cyborg Present: In the last decade, humans and machines have gotten closer than ever. We have machines that can read our memories, computers that let us type with our brains, and robotic arms controlled by monkey minds. Perhaps the most impressive cyborg advances have come in the last few months, with researchers hooking amputees up to robotic arms that not only respond to electrical signals from the human brain, but also provide tactile feedback.

The LHC Comes Online: The Large Hadron Collider has just begun colliding proton beams, but its construction represents one of the most ambitious scientific undertakings ever. The immense particle accelerator will hopefully give us first-hand observations of aspects of the universe that have been, thus far, the realm of theoretical physics. Despite fears from doomsayers that the LHC would destroy the world and a series of mishaps that led to claims that the device was being sabotaged from the future, the LHC came online this year and quickly got to smashing protons at record-breaking speeds.

Scientists May Have Found Dark Matter in Minnesota Mine

CDMS_zip_detector.jpg

Scientists believe they have found evidence of dark matter, the invisible substance believed to comprise three-quarters of the matter in the universe, in a defunct iron mine in northern Minnesota. The tentative detection of two dark-matter particles, known as weakly interacting massive particles (WIMPs) for their tendency to pass unimpeded through ordinary matter, was made by the Cryogenic Dark Matter Search (CDMS) project and announced by several laboratories, partners in a consortium that manages the project.

 Despite the announcement, project scientists acknowledge that there is still about a 25 percent chance that the detections were caused by some other unrelated effect, and that they will need at least five detections before they can definitively state they have found this mysterious form of matter.

University of Tokyo Unveils Flexible Organic Flash Memory

Flexible_Memory.jpgThe photo to the left shows an example of non-volatile, flexible organic flash memory developed at the University of Toyko–something that could lead the way to a slew of flexible computing gadgets, such as large-area sensors and electronic paper devices, Engadget reports.

The design uses a polyethylene naphthalate (PEN) resin sheet arrayed with memory cells, the report said; data can be written to it and erased over 1,000 times. The university claims it can be bent up to six millimeters without any degradation.

So far, it only retains data for about a day–but researchers expect to improve that drastically over time.

Flexible, organic flash memory on tap at the University of Tokyo

If the University of Tokyo has its way, we could be seeing an onslaught of flexible computing devices sooner than you think! Earlier this year the school made some noise with its stretchable OLED prototype and now a research group led by Takeo Someya and Tsuyoshi Sekitani has developed a non-volatile, flexible organic flash memory that may someday be used for large-area sensors, electronic paper devices, and non-volatile memory. Using a polyethylene naphthalate (PEN) resin sheet arrayed with memory cells, the memory can be bent until its curvature radius reaches 6mm without causing mechanical or electrical degradation. As it stands now, the device has a memory retention time of one day — but the team maintains that this can be “drastically improved by reducing the size of the element and employing an SAM with a long molecular length.” Piece of cake, right?

UCLA nanowire discovery could lead to faster, stronger, smaller electronics

Advancements in silicon-germanium have been going on for years now, but a team at UCLA is convinced that their discovery really is “the next big thing.” For scores now, microchip makers have struggled with miniaturizing transistors as the public at large demands that things get smaller and smaller. Thanks to researchers at the aforesaid university, it’s looking like silicon-germanium nanowires could be the key to making the process a whole lot easier. According to study co-author Suneel Kodambaka, the new nanowires could “help speed the development of smaller, faster and more powerful electronics,” also noting that they’re so small that they can be “placed in virtually anything.” Which is great, because the Adamo XPS is just entirely too pudgy.

NASA Launches WISE Infared Telescope

NASA_WISE_Telescope.jpgNASA has launched a new infrared space telescope that will scan the cosmos for asteroids and comets that could threaten our planet, CNN reports.

The Wide-field Infrared Survey Explorer (WISE) spacecraft lifted off at 9:09 am ET Monday from Vandenberg Air Force Base in California mounted to a Delta II rocket.

The telescope features an infrared camera for finding light- and heat-emitting objects that optical telescopes like Hubble could miss. WISE will orbit 326 miles above Earth for nine months. The report said its lens will eventually cover the entire sky one and a half times, snapping photos every 11 seconds.

WISE joins two other infrared telescopes, NASA’s Spitzer Space Telescope and the ESA’s Herschel Space Observatory, in orbit, though WISE is the only scope of the three mapping the entire sky.

NASA Resurrects Mars Orbiter

NASA_Mars_Reconnaissance_Orbiter.jpg

NASA has revived the $720 million Mars Reconnaissance Orbiter from its months-long slumber following a computer glitch, Space.com reports.

The MRO has unexpectedly rebooted several times over the past year. Back in August, the MRO fell into safe mode once again. But rather than rebooting it right away, NASA engineers spent the past several months figuring out what the root cause of the problem was. In the meantime, the craft’s safe mode preserved it from additional damage.

“The patient is out of danger, but more steps have to be taken to get it back on its feet,” said Jim Erickson, the spacecraft’s project manager at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, Calif., in the article.

NASA repaired the orbiter by uploading a software upgrade that patched a “potentially mission-killing scenario” in the spacecraft’s computer: back-to-back reboots.
