Manta5 pedal-electric hydrofoil takes to the lake – or sea

The Manta5 reportedly has a bit of a learning curve, but can easily be mastered

You could say that the the aquatic equivalent of the car is the motorboat, and the aquatic equivalent of the motorcycle is the Jet Ski – but what about the equivalent of the e-bike? That's what New Zealand outdoors entrepreneur Guy Howard-Willis wondered back in 2010, when he conceived of the Manta5. In the years since, bicycle designer Roland Alonzo brought the concept to life, in the form of an electric-assist pedal-powered hydrofoil bike. Now, it's just about ready to enter the market.

Blue Origin fires up its next big rocket engine for the first time

For the first time, Blue Origin successfully fired up its BE-4 rocket engine, a crucial piece of hardware the company has been working on for the last six years. Blue Origin tweeted out a video today of the test, known as a “hot fire,” which was conducted at the company’s test facility in Texas. It’s a major stepping stone in the development of the engine, which is slated to play a key role in Blue Origin’s economic future.

The BE-4 is slated to play a key role in Blue Origin’s future

Without the BE-4, Blue Origin’s future rocket wouldn’t fly. Currently, the company is developing a new reusable orbital rocket, called New Glenn, which is meant to be powered by seven main BE-4 engines at its base. Together, the engines will create a total...

We Have Found Ultra Rare Footage Showing A B-2 Spirit Stealth Bomber Dropping A 30,000-Pound Bunker Buster Bomb

This Is Probably The First Clip Showing The B-2 As It Drops The GBU-57 Massive Ordnance Penetrator. The B-2 Spirit stealth bomber is the only aircraft in the U.S. Air Force inventory currently capable to operationally drop the massive 30,000-lb (14,000 kg) GBU-57 Massive Ordnance Penetrator (even though the testing of the MOP involved a […]

Elon Musk gets permission to begin Boring Co. digging in Maryland

 Elon Musk’s week is going pretty great thus far, between meeting the creators of Rick & Morty and now gaining permission to dig even more tunnels — besides the one he already got the OK to begin digging closer to home in Hawthorne. Read More

Google officially flips on Project Loon in Puerto Rico


Puerto Rico is in trouble. Approximately 3 million of its residents are still without electricity after the island was devastated by Hurricane Maria, and 30% lack access to drinkable water. Exacerbating the process of recovery is the fact that communication infrastructure in general, and the internet specifically, is experiencing trouble across the U.S. territory.

Enter Alphabet's Project Loon, which on October 20 announced that it had officially switched on its balloon-powered internet for some Puerto Rican residents. That's right giant balloons are providing digital connectivity for some people who might otherwise go without.  Read more...

One of the great challenges in visualizing fluid flows is the...


One of the great challenges in visualizing fluid flows is the freedom of movement. A fluid particle – meaning some tiny little bit of fluid we want to follow – is generally free to move in any direction and even change its shape (but not mass). This makes tracking all of those changes difficult, and it’s part of why there are so many different techniques for flow visualization. The technique an experimenter uses depends on the information they hope to get. 

Often a researcher may want to know about fluid velocity in two or more directions, which can require multiple camera angles and more than one laser sheet illuminating the flow. An alternative to such a set-up is shown above. The injected fluid – known as a rheoscopic fluid – contains microscopic reflective particles, in this case mica, that are asymmetric in shape. Imagine a tiny rod, for example. By illuminating the rod from different directions with different colors of light, you can determine the particle’s orientation based on the color it reflects. Since the orientation of the particle depends on the surrounding flow, you can infer how the flow moves. (Image credit and submission: J. C. Straccia; research link: V. Bezuglyy et al.)

Apple Store Opens in Chicago

Today the Apple Michigan Avenue store opens to the public. Designed by Norman Foster, the store replaces the older Bohlin Cywinski Jackson store a few blocks up Michigan Avenue. Like other recent Apple stores around the world, this one is more lightweight, transparent and outwardly simpler than older stores.

The store is also a symbol of Chicago's move toward the river, something it has been doing with the Chicago Riverwalk (south side of the river, roughly between Michigan Avenue and Lake Street) and projects like this one on the north side of the river and the new CAF location opening across the river from Apple next year.


Although I've yet to see the completed store in person, these photos give the impression that the building is a good neighbor, both in the way it knits and visually connects the plaza at Pioneer Court to the riverwalk below, and in the way the construction fits into the Miesian tradition in Chicago. The latter is most pronounced in the way surfaces appear continuous from inside to outside through the super-clear laminated glass walls, particularly the steps and the wood ceiling. The photos give the impression that it feels like an Apple store, but at the same time it's a very site-specific way of inserting one into the city.

iOS 11 Installed on Almost 55% of Devices One Month After Launch

One month after its official public release, iOS 11 has been installed on 54.49 percent of devices, according to data collected by analytics company Mixpanel.

iOS 11 was first released on September 19, and while adoption has been rather slow compared to iOS 10 adoption, it is steadily picking up. At the one week mark, iOS 11 was installed on 25 percent of devices, and at two weeks, installation climbed to 38.5 percent of devices.

At three weeks, iOS 11 adoption reached 47 percent, successfully overtaking iOS 10, and the gap between the two operating systems has continued to widen. With iOS 11 on nearly 55 percent of devices, iOS 10 is now installed on just 39.17 percent of devices. 6.34 percent of devices continue to run an older version of iOS.

Apple has released three minor updates to iOS 11 so far to address bugs and issues discovered since the launch of the new operating system. The most recent update, iOS 11.0.3, fixed an issue with haptic feedback and unresponsive displays, while iOS 11.0.2 addressed an irritating problem that caused the iPhone 8 and 8 Plus earpiece to crackle on phone calls.

iOS 11 adoption is likely to increase significantly when iOS 11.1 is released, if past iOS launches are any indication. Major .1 releases often spur people to update, and iOS 11.1 introduces new emojis and may include Apple Pay Cash, Apple's peer-to-peer Apple Pay feature. In past years, new emoji have had a noticeable impact on upgrade rates.

The iOS 11.1 update also fixes some lingering bugs, including one that caused Reachability to work improperly, and it addresses a serious WPA2 Wi-Fi vulnerability. It's not yet clear when Apple plans to release iOS 11.1, but there have been three betas thus far.
