A tree that produces 40 types of fruit

Science Alert reports: [edited]

In 2008, Van Aken learned that an orchard at the New York State Agricultural Experiment Station was about to be shut down due to a lack of funding. This single orchard grew a great number of heirloom, antique, and native varieties of stone fruit, and some of these were 150 to 200 years old. To lose this orchard would render many of these rare and old varieties of fruit extinct, so to preserve them, Van Aken bought the orchard, and spent the following years figuring out how to graft parts of the trees onto a single fruit tree.

Working with a pool of over 250 varieties of stone fruit, Van Aken developed a timeline of when each of them blossom in relationship to each other and started grafting a few onto a working tree’s root structure. Once the working tree was about two years old, Van Aken used a technique called chip grafting to add more varieties on as separate branches. This technique involves taking a sliver off a fruit tree that includes the bud, and inserting that into an incision in the working tree. It's then taped into place, and left to sit and heal over winter. If all goes well, the branch will be pruned back to encourage it to grow as a normal branch on the working tree.

After about five years and several grafted branches, Van Aken's first Tree of 40 Fruit was complete. It looks like a normal tree for most of the year, but in spring it reveals a stunning patchwork of pink, white, red and purple blossoms, which turn into an array of plums, peaches, apricots, nectarines, cherries and almonds during the summer months, all of which are rare and unique varieties.

Not only is it a beautiful specimen, but it’s also helping to preserve the diversity of the world’s stone fruit. Stone fruits are selected for commercial growing based first and foremost on how long they keep, then how large they grow, then how they look, and lastly how they taste. This means that there are thousands of stone fruit varieties in the world, but only a very select few are considered commercially viable, even if they aren't the best tasting, or most nutritious ones.

Van Aken has grown 16 Trees of 40 Fruit so far, and they’ve been planted in museums, community centres, and private art collections around the US. He now plans to grow a small orchard of these trees in a city setting. Of course, the obvious question that remains is what happens to all the fruit that gets harvested from these trees? Van Aken told Lauren Salkeld at Epicurious:

"I've been told by people that have a tree at their home that it provides the perfect amount and perfect variety of fruit. So rather than having one variety that produces more than you know what to do with, it provides good amounts of each of the 40 varieties. Since all of these fruit ripen at different times, from July through October, you also aren't inundated."

Panasonic Lumix DMC-FZ1000

Digital Photography Review has published a full review of Panasonic's premium superzoom.

Snippets from the conclusion follow:

"The DMC-FZ1000 is one of the most exciting 'compact' cameras to come along in some time. The combination of a 1"-type sensor and bright 25-400mm lens make the FZ1000 a compelling choice for both the traveler and someone who wants a camera that does both stills and video very well."

"The FZ1000 is the first compact camera to support 4K video recording (at an impressive 100Mbps bit rate), so it's ready for the next generation of televisions."

"Exposure is generally accurate, with highlight clipping not being a huge issue. Colours have a nice vivid look to them, without being over-the-top like some other consumer-level cameras."

"Panasonic has taken a relatively conservative approach to noise reduction, leaving more grain than the Sony RX10, which tends to brush away fine detail. The FZ1000 maintains fine detail until about ISO 3200 and you can comfortably shoot a stop higher, after which you'll want to downsize or switch to Raw."

W"hile image quality is close to that of interchangeable lens cameras at their base ISOs, the FZ1000 falls behind relatively quickly due to its smaller sensor. That said, no ILC offers the same combination of size, video, and price as the FZ1000."

"Video quality is excellent. 4K video also allows one to capture 8 megapixel stills, which look very good. The 1080p video is top-notch."

"The FZ1000 is one of the most responsive compacts we've seen, whether it's startup speed, autofocus, or the user interface. The autofocus speed is what really stands out, regardless of the lighting condition. The FZ1000 has an available electronic shutter, which allows for silent shooting. You can compose your photos and movies on either a fully articulating 921k dot LCD or via a gorgeous XGA electronic viewfinder."

Bacteria that lives on electricity

Engadget reports: [edited]

All life is ultimately powered by electricity, albeit indirectly, since most organisms consume sugars that produce electrochemical reactions. Several types of bacteria are known to skip the sweets and go straight for the electrons, however - and researchers have discovered that they may be everywhere.

New Scientist reported that biologists have grown bacteria (Mariprofundus ferrooxydans PV-1) that harvest electrons directly from iron electrodes. Several species were teased out of soil from a seabed floor and deep well in Death Valley, California, just by applying a charge to the ground. In a lab environment, a separate team found that they can be kept alive exclusively with electricity.

Scientists found that up to eight species may eat and excrete electrons, including some with remarkable properties. For instance, hundreds of thousands of bacteria can form daisy-chained "wires" an inch or so long, and tap seawater oxygen for energy. Such filaments can hold soil together and conduct electricity about as well as standard copper wire. Those properties could lead to interesting practical applications, like "SPUDs" or self-powered useful devices that clean up pollution, or bacteria that create electric "biocable" networks in the soil.

New Tooth Decay Treatment

The Guardian reports: [edited]

Scientists have developed a new pain-free filling that allows cavities to be repaired without drilling or injections. The tooth-rebuilding technique developed at King's College London does away with fillings and instead encourages teeth to repair themselves.

Tooth decay is normally removed by drilling, after which the cavity is filled with a material such as amalgam or composite resin. The new treatment, called Electrically Accelerated and Enhanced Remineralisation (EAER), accelerates the natural movement of calcium and phosphate minerals into the damaged tooth.

A two-step process first prepares the damaged area of enamel, then uses a tiny electric current to push minerals into the repair site. It could be available within three years. Professor Nigel Pitts, from King's College London's Dental Institute, said: "The way we treat teeth today is not ideal. When we repair a tooth by putting in a filling, that tooth enters a cycle of drilling and refilling as, ultimately, each 'repair' fails.

"Not only is our device kinder to the patient and better for their teeth, but it's expected to be at least as cost-effective as current dental treatments. Along with fighting tooth decay, our device can also be used to whiten teeth."

LG G Watch Review

Wired has published a review of LG's Android smartwatch.

Snippets follow:

"The company’s new G Watch is the first of three Android Wear smartwatches — the other two being the Motorola Moto 360 and Samsung Gear Live. It comes with an always-on, 1.65-inch LCD display and a 1.2 GHz Snapdragon processor with 4 GB of memory."

"the G Watch feels like the worst parts of your smartphone strapped to your wrist, plus Google Now and some third-party app integration."

"the G Watch comes with a 280 x 280 pixel resolution LCD display that’s bright and clear, although it’s unreadable in bright sunlight. A replaceable 22mm synthetic band straps that LCD watch face to your wrist. The band, inlaid with shallow diamond-shaped indentations on the inside, feels very thick. It never blends seamlessly into your daily experience — you’re aware there’s a watch there. Its rectangular face measures approximately 38mm x 47mm x 10mm."

"While Android Wear has promise — the user interface is clean and intuitive, and there’s a clear, easy way for third party developers to get their apps onboard — it’s hardly a saviour for our smartphone woes. In fact, the watch is mostly a hell of constant, vibrating notifications. You can cease the constant buzzing by going into the Android Wear app and selecting which ones you don’t want notifications from; you can also temporarily silence the watch. But in both cases, it silences indiscriminately."

Luckily there’s far more to the watch than just Gmail notifications. Android Wear’s third party app ecosystem promises to open up infinitely more use cases. After granting developers access to its API on the 7th, there are currently 33 Android Wear-optimised apps, including software from entities like Pinterest, Runtastic, Eat24, and BandsInTown."

"One thing LG’s G Watch does do well is voice control. You don’t even have to hold the watch up to your face, a simple utterance of “OK Google” instantly brings up the voice command interface, letting you record a note, set an alarm, make a simple query, search directions on Google Maps, and more. When you get a text or Hangout, you can dictate and send a reply straight from the watch. It does a stellar job of interpreting what you say so long as you’re in a reasonably quiet location."

"The G Watch is water and sweat resistant, but it isn’t truly waterproof. It charges in a small cradle that the watch face magnetically snaps into. You can easily use 80 to 100 percent of its battery in a day, so you’ll want to keep this charging cradle at your office desk or by your bedside."

"The goal of wearables, smartwatches in particular, is to free you from your smartphone dependence. “Look, now you don’t need to pull your phone out of your pocket to check what that notification was. A discreet glance at your wrist will let you know if it’s important or not!” False. When your wrist is vibrating constantly it’s both irritating and distracting for you and everyone else around you. And unlike a smartphone tucked away in a bag or pocket, you can’t ignore it."

IBM investing 3 billion dollars in graphene chip research

The Register reports: [edited]

IBM's big blue scientists have been given the money to solve a problem that lurks not so far in our future. That problem is the imminent breakdown in conventional chip operation and chip materials as we shrink transistor gates from today's 14nm process size to 10nm and 7nm.

At around 7nm, which most industry observers expect we will hit in the early 2020s, more and more jostling electrons will jump in and out of gates, leading to a frustrating problem known as gate current leakage.

The company sees carbon nanotubes (CNT) as a good candidate for the replacement of silicon as they are "three to ten times better than silicon tech on a [process] node-to-node basis". Production of CNT at mass scale is ramping up as well, he said: "You have to make carbon nanotubes with purity levels that are six nines. Today we are at four nines and over a year ago [we were] at 98.5 percent."

Alongside CNT, IBM is also working on III-V MOSFETs, which are transistors designed to better cope with the aforementioned leakage problems.

Enabling Email Send Undo in Gmail

osxdaily reports: [edited]

If you’ve ever sent an email that you immediately realised wasn’t complete, contained errors, or, even worse, was to the wrong person, you know that feeling of dread. For web-browser Gmail users, an optional setting offers a layer of forgiveness to those situations, providing the ability to recall a sent email.

Go to and log in to your Google account as usual.

Click on the gear icon/settings button in the upper right corner of the Gmail inbox window, then choose the “Settings” option from the pulldown menu.

Select the “Labs” tab. Locate “Undo Send” by ‘Yuzo F’, check the “Enable” radio box and click 'Save Changes' at the bottom of the window.

Next, go to the “General” tab within Gmail Settings, locate the “Undo Send” option and adjust your recall email/undo send cancellation period. Again scroll to the bottom and select “Save Changes”.

To use the feature, send any email, and you’ll find an “Undo” option available next to the “Your message was sent” box that shows up in yellow at the top of the screen.

When you click “Undo” the email becomes unsent, returns and becomes a draft, allowing you to amend and resend the message.

Toyota Free Piston Engine

Road & Track reports: [edited]

Electrically driven cars are the future. But until we have cheap, 1000-mile batteries, we still need range-extending fossil-fuel engines. The simple solution is to strap a generator to a piston engine, as BMW did with the two-cylinder range extender in its i3 EV. But if the engine never turns a wheel, there's no need for it to rotate anything. Why not cut out the middleman and use the piston's reciprocating motion to generate electricity? That obviates camshafts and most other rotating parts, too.

Toyota recently showed a prototype engine that does just that. It's called the Free Piston Engine Linear Generator (FPEG). "Free" refers to the fact that the piston isn't attached to a crankshaft; instead, as the piston is forced downward during its power stroke, it passes through windings in the cylinder to generate a burst of three-phase AC electricity. The FPEG operates like a two-stroke engine but adds direct gasoline injection and electrically operated valves. It can also be run like a diesel, using compression rather than a spark plug to ignite its fuel mixture.

Toyota says this mechanically simple engine achieves a claimed thermal-efficiency rating of 42 percent in continuous use. Only the best, most complicated, and most expensive of today's gas engines can come close to that number, and only in specific circumstances. Even better, a two-cylinder FPEG is inherently balanced and would measure roughly 8 inches around and 2 feet long. An engine of that size and type could generate 15 hp, enough to move a compact electric vehicle at highway speed after its main drive battery has been depleted.

Sony Cyber-shot DSC-RX100 III Review

Digital Photography Review has published a full review of the latest incarnation of Sony's premium compact camera.

A précised version of the 'final word' follows:

The RX100 III provides better image quality than any camera its size ever has. Add to this an impressive and comprehensive feature set and it looks like the very definition of a stand-out camera.

In terms of shooting experience, the RX100 III continues to feel more like a camera that will somewhat grudgingly let you take control, rather than an enthusiast camera designed for the committed photographer from the ground up.

However, the breadth of its capabilities, from its bright, flexible lens and handy viewfinder, through to its class-defining image quality and well-supported, high-quality video capture mean there's nothing to really match it. And if you mainly shoot in P or Auto mode, you may never experience our frustrations about the handing.

The RX100 series has always been technically impressive, but the addition of the brighter lens, viewfinder and ND filter extend its utility to a huge degree. Owners of its predecessors should seriously consider upgrading unless they need more zoom reach.
