Hebes Chasma, a huge trough on Mars, reflects the Red Planet’s tumultuous and varied past. During the planet’s first billion years, the nearby Tharsis Region bulged with magma, then burst apart, forming enormous chasms such as Hebes (a majority of its 315-kilometer length shown above). More than four times as deep and wide as the Grand Canyon, Hebes may have once been filled with water; some areas have minerals that could have formed only in water’s presence. New images from the European Space Agency’s Mars Express spacecraft show that massive landslides may have shaped and widened the trench since its violent birth.
Scientists have discovered a “lost world” of unknown creatures in a remote rainforest perched on a giant boulder plateau in Queensland, Australia.
In an expedition bearing parallels to Arthur Conan Doyle’s classic novel, the team of biologists found three unidentified reptile species living on the upland plateau, which is accessible only by helicopter because of a “monstrous wall” of “millions of giant, piled up boulders the size of houses and cars”.
It is believed that the species have been isolated from their closest cousins for millions of years. “We’re talking about animals that are ancient” said Dr. Conrad Hoskin, from James Cook University. (Photo: CONRAD HOSKIN/AFP/Getty Images)
A remarkle feat of engineering now joins Europe to Asia at the Bosphorus.
It’s been a long time since Istanbul was an economic focal point between Asia and the West. But, yesterday, at the opening of the deepest underwater railway ever built, Turkish officials described their vision to “restore the Silk Road” and link London with Beijing—thanks to a Japanese-funded railway beneath the Bosphorus.

I was also intrigued by a crater shown at the 1:50 mark, which looks like it got filled by a landslide off a nearby hill. Mars isn’t what you might call geologically active, but it does commonly suffer landslides and avalanches when the frozen carbon dioxide ice under the surface sublimates (turns directly from a solid into a gas), which can dislodge material. If that happens at the top of a hill or cliff, material can cascade down dramatically. I strongly suspect that’s what we’re seeing in this video.
A 3D printed robotic prosthetic hand which is a fraction of the cost compared to current available models - video embedded below:
The Open Hand Project aims to make advanced prosthetic hands more accessible to amputees. The Dextrus hand is the realization of this goal, it’s a low-cost robotic hand that offers much of the functionality of a human hand. Ultimately, these hands will be sold for under $1000 (£630).
The Open Hand Project is open-source, which means all of the plans to make a robotic hand will be published online with no patents, anyone has the right to make their own and even sell it themselves. You’re funding the full development of the hand with the Open Hand Project, after that companies will be able to use the designs and sell the hands all over the world. This really helps get these devices out to developing countries and places where import taxes might otherwise increase the cost of distribution.
The project is looking for funding through an indiegogo campaign - more info can be found here
