Morpheus lander crashes, burns and explodes in untethered flight test, NASA remains optimistic

As noisy as we found Project Morpheus’ tethered flight test, its untethered follow-up was far, far louder. Yesterday, the experimental lander suffered a hardware component failure, which NASA says “prevented it from maintaining stable flight.” This caused it to crash into the ground and well, explode. On the upside, the space agency says that these kinds of failures were anticipated, stating that they are a normal part of the development process and will be used to build better systems moving forward. You didn’t think Curiosity made its touchdown on Mars without learning from a few mistakes, did you? Click onwards to check out the test — and its aftermath — in 5, 4, 3, 2, er…

Disney creates Botanicus Interacticus multi-touch plants

The last thing in the world I would’ve ever believed could be turned into a touch sensor would be a plant. However, that is exactly what Disney’s Pittsburgh research center has done in a project called Botanicus Interacticus. I can only imagine a full-size attraction at Disneyland or Disneyworld packed with touch sensitive plants.

This may well be the first step to creating something along the lines of the plants in the science-fiction film Avatar that create a light show when touched. Disney plans to pair the touch-sensitive plants with a visual display to allow input to be projected back to the user in a visual form. Disney created the interactive plants by embedding an electronic sensor into the soil of a normal plant.

The researchers then recorded the interruption of electric signals that occur when people touch the plant. After scrutinizing the readings from the sensor embedded in the dirt, the team was able to recreate the living plants as artificial plants with the exact same conductive properties of the real version. Turning the real plants into artificial plants would be a necessity because real plants would be unable to withstand constantly being poked, prodded, and squeezed by people at an exhibit.

You can check out both of the videos below to see the Botanicus Interacticus plants in action. This is a very cool invention. I wonder if this technology might be viable for security systems where plants would be able to alert a homeowner or business to intruders on their property when the plants are touched.

Chemical sensors could detect plants’ cries for help, reduce need for pesticides

Image

It’s a terrifying thought, but science suggests that when under attack, plants cry for help. Invisible and, often odorless, green leaf volatiles emitted from vegetation act as a defense mechanism, communicating to other foliage that danger is near. One researcher at the University of Georgia, however, is developing a chemical sensor to use these distraught emissions for good. Working in a similar fashion detecting glucose in the blood, the sensor would be able to alert farmers to when crops are under attack from pests, allowing them to trigger defenses reactively, and in a localized area. The net result being less chemicals on our food, and potentially lower costs for producers. Other suggested uses include helping us keep our produce at home fresher for longer by — literally — weeding out bad apples in a bag, before they affect the others. The technology is still being optimized for field use, but a testing device should follow once complete. In the meantime, we’ll never feel the same about mowing the lawn again.

Paleontologists Discover fossils believed to be from two new pre-human species

A team of paleontologists led by Meave Leakey has found some facial bones coming from one creature and jawbones from two others in a Kenyan dig. The fossils go back almost 2,000,000 years, and the paleontologists believe that these bones will confirm the theory that there were two additional pre-human species other than the one they believe led to modern humans.

The paleontologists believe that the bone shows that early human ancestors had company from other human-like species. The scientists say that the bones found would not be of the Homo erectus, Homo erectus is believed to be the direct ancestor of modern humans. The new bones go back further in time, and the scientists believe the bones showed the new creature and Homo erectus shared an ancient common ancestor. The scientists say that the recently discovered fossils would be more akin to very distant cousins to Homo erectus.

However, not all experts on the matter agree. Other experts believe that Leakey and her team are jumping to conclusions based on limited evidence. However, Leakey and her team maintain that none of the new fossils discovered are a match for Homo erectus and therefore have to be from another flat-faced, large species with big teeth.

Interestingly, the newly discovered bones did match old fossils that Meave Leakey, and her husband, helped discover in 1972. The new skull fragments match another skull called 1470. That particular skull caused a controversy in the paleontology community when it was ruled that the skull had been incorrectly dated. The 1972 skull was originally dated at more than 2.5 million years old and was later found to be more than 2 million years old. Other evidence leads the Leakeys to believe that there were three living Homo species between 1.8 and 2 million years ago including Homo erectus, the 1470 species, and a third branch with smaller heads.

Gartner: HP Keeps Its PC Lead As European Market Drops 2.4%, Apple Cracks Top 5 In UK

Image (1) hp_3d_laptop.jpg for post 178938

Tablets and smartphones may be gradually ushering us into a post-PC world, but for now the bigger machines continue to dominate the market. Figures out today from Gartner, focusing on PCs in Europe, note that shipments in the economically-troubled region declined by 2.4% to 13.6 million units in Q2, in a wider global market where growth was flat. Within that, HP kept its lead as the biggest PC maker, while Apple has managed to crack into the top-five PC makers in one market, the UK.

The wider trend seems to be that even in PCs, people are gravitating towards smaller machines. Gartner notes that desk-based units were down by 12.8 percent, but mobile PC shipments (laptops, netbooks) went up by 4%. Similarly, you can see the effects of consumerization at play here: the “professional” PC market is down by 5.3%, while consumer PCs saw a sliver of growth: 0.4%.

Europe accounts for about 16% of the global market for PCs (globally there were 87.5 million PCs shipped in the quarter). In the region, HP currently controls 20% of the market, down from 23 percent in Q2 a year ago. It shipped 2.8 million units, 13% less than last year, while Acer, Asus and Lenovo all grew their shares, with Asus posting the most impressive increase at 42%. HP retained the lead in all individual markets except for Germany, where it dropped to third and Acer now leads. (HP will be reporting quarterly earnings later in the month and that will give us a more accurate picture of what is going on.)

Gartner notes that Dell declined the most among the top-five vendors. It dropped down for third-largest to fourth-largest PC maker, with a share of 8.7 percent (1.2 million units, a decline of 13.6%).

Asus’s rise, Gartner notes, was down to the company offering a wide range of devices between mobile and desktop PCs, as well as Ultrabooks and tablets, “all of which are marketed at attractive prices,” according to Meike Escherich, principal analyst at Gartner. Dell’s decline is partly attributed to how it has largely started to pull away from PC maker to professional services supremo — although it seems to be doing that bang off trend, given the decline in the professional market. (In the UK market, its shift saw Dell lose some 40 percent share in consumer PCs, Gartner pointed out.)

Given that there will be a wave of new machines coming on the market with Windows 8 in the lead-up to the holiday season, if sales don’t pick up now, you may start to see some real bargains on the market. The knock-on effect will be tricky for Microsoft and Windows 8. As a result of the price cut on older machines, “challenges may arise in selling new products into the channel in the third quarter of 2012,” she noted.

As for how individual markets are performing, the rankings are largely a reshuffling of the European top-five, with one notable exception. In the UK, Apple and Toshiba are part of the mix, and Lenovo and Asus are not.

HP retained the top position in the UK, but Apple squeezed in at fifth position with 187 million units sold, for a 7.4% share of the market. Toshiba, meanwhile, saw a very healthy growth of 51.6% for a 0.4 share of the market (238 million units).

Still, the UK was “very weak” in Q2 with an overall decline of 7.6 percent, beating the European average and well below the state of the global market.

And with the move to smartphones and tablets particularly strong in the country — it was one of the first developed markets to have a majority-smartphone penetration among mobile users — PCs might continue to fare poorly even when economic conditions get better:

“The real worry for the UK PC market is whether it will ever return to solid growth,” writes Ranjit Atwal, a Gartner research director. “Windows 8 and Ultrabooks now look even more important. However, messages emerging from the PC supply chain remain inconsistent and largely uninspiring.” He notes that in the UK, the PC channel will be ”holding back on new shipment orders” until Q4 2012 to try to shore up demand.


iPad estimated to be cornering nearly 73% of Chinese tablet market

iPad estimated cornering nearly 73% of Chinese tablet market

We’re used to seeing tablet market share illustrated on the world stage. China, however, has usually been untouched. Analysys International has taken a crack at decoding the market and has bucked a few expectations in the process: according to its estimates, the iPad’s lead is even larger in China than it is worldwide. About 72.7 percent of all tablets sold in the country during the second quarter were Apple-flavored, while homegrown hero Lenovo was a distant second at 8.4 percent. Everyone else had to contend with less than four percent and reflected the more diverse Chinese technology sphere — relative heavyweights like Acer, ASUS and Samsung had to hob-nob with brands that have little recognition elsewhere, such as Eben and Teclast.

The researchers credit Apple’s lead, a 7.8-point gain, to a combination of the new iPad and a price-cut iPad 2. We’d add that Analysys’ figures might not tell the whole story, though: China is well-known for its thriving shanzhai market, where legions of KIRFs and very small (usually Android-based) brands likely slip under an analyst group’s radar. That said, it’s still an illustration of how Apple’s influence in tablets is a distinct reversal of its much smaller smartphone share, even in a nation that’s a hotbed of Android activity.

Scientists generate 281-gigapixel cell map using electron microscope

Scientists generate 281gigapixel cell map using electron microscope

Electron microscopes can produce incredibly detailed and even 3D views of sub-cellular structures, but often at the cost of losing the bigger picture. Researchers at Leiden University in the Netherlands, however, have leveraged a technique called virtual nanoscopy that enables researchers to observe the whole of a cell and its intricate details in a single image. With the method, the team stitches together nanometer resolution photographs of what’s gone under the scope to create a map with adjustable zoom a la Google Maps. Their study created a 281-gigapixel image (packed with 16 million pixels per inch) of a 1.5-millimeter-long zebrafish embryo. If you’d like to take a gander at the ultra-high resolution fish or read up on the group’s findings for yourself, check out the source links below.

NASA’s Morpheus lander detects hazards, noisily passes tethered flight test (video)

Morpheus lander gets demoed,

While it’s not landing on Mars any time soon, NASA took a breather from Curiosity’s adventures to showcase the Morpheus Lander. The prototype went through its first (tethered) flight test at the Kennedy Space Center just before the weekend, showcasing its methane-powered rocket system. It’s this rocket setup which could make the Morpheus Lander a strong candidate for future landings. It’s both safer than rocket fuel and NASA suggests that methane gas discarded from the International Space Station could be enough to top up the lander’s fuel tanks without necessitating a visit back to Earth. Morpheus’ built-in guidance system also reduces the amount of input needed from mission control — the pod has been practicing hard on its own hazard field near the Space Center. After passing the test with its training wheels on, the first free flight descent has been tentatively penned in for later today. Crank the volume low — it gets loud — and watch Morpheus test those right rockets after the break.

Georgia Tech models swimming, cargo-carrying nanobots

Georgia Tech models swimming, cargocarrying nanobots

The nanobot war is escalating. Not content to let Penn State’s nanospiders win the day, Georgia Tech has answered back with a noticeably less creepy blood-swimming robot model of its own, whose look is more that of a fish than any arachnid this time around. It still uses material changes to exert movement — here exposing hydrogels to electricity, heat, light or magnetism — but Georgia Tech’s method steers the 10-micron trooper to its destination through far more innocuous-sounding flaps. Researchers’ goals are still as benign as ever, with the goal either to deliver drugs or to build minuscule structures piece-by-piece. The catch is that rather important mention of a “model” from earlier: Georgia Tech only has a scientifically viable design to work from and needs someone to build it. Should someone step up, there’s a world of potential from schools of tiny swimmers targeting exactly what ails us.

NASA Curiosity landing video: Relive the peanuts moment

NASA’s Curiosity rover may be getting to grips with its new home, but if you didn’t stay up (or get up) to watch the momentous “Seven Minutes of Terror” landing then here’s the video you need to see. The culmination of a 39-week journey from Earth to Mars, the descent was completely programmed as, thanks to time-delays of around fourteen minutes between NASA control and the Curiosity lander and Skycrane itself, there was no way it could be actively remote controlled. Cue several nail-biting minutes as NASA’s Jet Propulsion Laboratory stayed glued to its telemetrics.

In fact, those telemetrics were of a journey that had already begun and ended: by the time the first signs of Curiosity hitting Mars’ upper atmosphere appeared on their screens, the condition of the landing – safe or otherwise – had already been decided. That certainly explains the anxious faces and – eventual – glee of the team when the numbers begin to come through.

Confused by the “peanuts tradition” references you may have heard about the landing? Apparently the good-luck practice began after the first successful Ranger program to land on the moon, which coincided with a Jet Propulsion Laboratory team member eating peanuts. Now, every mission begins with some peanuts to keep channeling that track record.

Curiosity landing video:

Since Curiosity and the Skycrane couldn’t beam back their own footage, NASA’s own renderings of the landing process gives more details on the challenge the JPL team undertook. There are images from the first batch beamed back to Earth from Curiosity here.
