They may look ungainly, but the aerodynamic advantages of recumbent bikes and trikes give them an edge – especially if you throw a 4 kW wheel hub motor into the mix.
Storms brought misery to Britain last week as 90mph winds brought down trees, blocked roads and caused travel chaos.
But for those living in certain areas, the gales brought the very real headaches caused by screeching buildings and ‘singing’ skyscrapers.
A number of buildings have been heard giving off whistling noises during blustery weather, usually caused by architectural features added to the outside.
Torbay Hospital is the latest modern building to discover a ‘whistling’ problem in high winds
Torbay hospital is the latest to be added to the list, where locals noticed that a new metal facade on the building was whistling in the wind.
But the health centre is not the first to be hit by the issue. The Beetham Tower in Manchester has developed a reputation for howling, humming and whistling every time the wind picks up, prompting repeated attempts to tackle the problem.
A self-driving Tesla comes with a hefty price tag, but a college student has given his Honda Civic similar abilities for a fraction of the cost.
Brevan Jorgenson has unveiled a device that replaces the rear-view mirror, which controls the brakes, accelerator and steering – and it only cost $700 to build.
The DIY device uses the hardware design and software shared online by Comma.ai last year, which had originally planned to upgrade cars with the technology.

The camera in the iPhone 7 Plus was deemed the ‘future of photography’ – but the technology set for the 10th-anniversary is said to be ‘revolutionary’.
An analyst has revealed that Apple is planning on implementing a front-facing camera with an infrared module that senses 3D space in the iPhone 8 handset.
This system could be used for a range of applications including, snapping a selfie that would be added to an augmented world, facial recognition or iris scanning.

The latest rumor regarding Apple’s iPhone suggests it will have a front-facing camera and infrared module that senses 3D space.
The sensors in the phone are said to detect the location and depth of objects around it.
The complete 3D system would send invisible IR light signals out from the phone and then wait for them to hit objects and return using the 1.4 megapixel IR receiver.
The camera would be used for a range of applications including, placing the user’s face on a character in a game, facial recognition, iris scanning and overall improved selfies.

A recent investigation into poultry sold at major fast-food restaurants in Canada suggests that Subway’s chicken could be more accurately named “only about half chicken.”
Last month, DNA researcher Matt Harnden, who works at Trent University’s Wildlife Forensic DNA Laboratory, tested the DNA of the poultry from six popular fast-food chicken sandwiches at five different restaurants.
Firearms have come a long way from the days of the musket and flintlock, but they’re also much more complicated and involve trade offs. In preparing for missions, soldiers are often forced to choose between a close quarter or a magnified sight for their assault rifles as there’s no one-size-fits-all solution.
The ancient art of origami has been inspiring engineers and designers for decades. The principles behind this Japanese folding technique have been appropriated by everyone from solar array designers for implementation in space to medical engineers creating ingestible robotics. Now a team at Brigham Young University (BYU) has created a lightweight bulletproof shield inspired by a Yoshimura origami crease pattern.
Levitation may look like magic, but there are a number of scientific tricks behind it. Magnetic systems are usually behind gimmicky consumer products like floating lightbulbs and speakers, optical levitation turns up in more academic pursuits like quantum computing, and acoustics could help suspend tiny particles to make better drugs. These techniques only work with certain objects, but researchers at the University of Chicago have developed a method to levitate basically anything, using differences in temperature.
“Magnetic levitation only works on magnetic particles, and optical levitation only works on objects that can be polarized by light, but with our first-of-its-kind method, we demonstrate a method to levitate generic objects,” says Cheng Chin, one of the researchers on the team.
Balls of ceramic, plastic and glass, ice particles, seeds and pieces of lint have been used to demonstrate the technique, and the team found that the levitated particles could be held aloft for over an hour rather than a matter of minutes, and wouldn’t wobble around sideways.
The researchers achieved this versatile levitation through the process of thermophoresis, which manipulates particles by placing them between sources of different temperatures. In this case, the objects were placed in a vacuum between two plates – the bottom one, made of copper, was left at room temperature, while the top plate contained liquid nitrogen, cooling a stainless steel container to -300º F (-184º C). The relative heat would flow from the bottom plate toward the top one, lifting the particles along with it.
They became extinct thousands of years ago, but now scientists claim they are just two years away from bringing woolly mammoths back from the dead.
The shaggy beasts last wandered the tundra of Siberia before our human ancestors probably hunted them into extinction.
Now a project to bring back the mammoth said within two years the nearest possible thing to a mammoth could be created.
It would be a hybrid between an Asian elephant and a mammoth – perhaps you could call it a ‘mamephant’.
