Algorithm predicts the Price of Bitcoin – Developers Double Their Investment in 50 Days

bitcoin

A team at MIT has developed a prediction algorithm that allows them to determine when the price of the infamous volatile cryptocurrency, Bitcoin, will drop or rise. Using this method, the researchers managed to double their initial investment in 50 days, all through an automated process that involved more than 2,800 transactions. Money forecast Since the last year or so, Bitcoin…

Tractor beam smashes existing records

Drs Shvedov (L) and Hnatovsky used a doughnut-shaped laser beam to push and pull small glass spheres

A team of scientists has managed to develop a tractor beam which can pull and push objects over 20 cm – 100 times more than previous records. There are a myriad of potential applications for this kind of research, including studying atmospheric pollutants or retrieving delicate particles of material for examination. “Recent advances in lightwave technology have already led to small-scale…

There are over 4 billion IP addresses registered all over the globe and this number is constantly growing as developing countries get wired and more people use smartphones and tablets. The internet isn’t the same all over the world (yet) and activity heavily fluctuates from day to night. A new study mapped the world’s internet activity using an extremely simple…

A team at Harvard’s Wyss Institute for Biologically Inspired Engineering demonstrated the latest advances in programmable DNA self-assembly by crystallizing 32 structures with precisely prescribed depths and complex 3D features. The DNA crystals could potentially be used as the basis of a programmable material platform that would allow scientists to build extremely precise and complex structures rivaling the complexity of…

Researchers from Columbia Engineering and the Georgia Institute of Technology report the first experimental proof of piezoelectricity and the piezotronic effect in an atomically thin material, molybdenum disulfide (MoS2), making the experimental setup, in effect, the thinnest electrical generator in the world. The resulting generator is optically transparent, extremely light, and very bendable and stretchable. In the future, such generators could be…

Houses of the future might be built with bacteria – at least partially. It may sound like science fiction, but a Spanish company located in Madrid is working to make that a concrete reality. It all starts with a common type of soil bacterium being. Put it in some soil, provide it with nutrients, and keep the temperature steady at about 30…

At MIT’s self-assembly lab, materials turn to life

carbon_fiber

A highly fascinating and, surprisingly for some, practical new line of research is concerned with programmable materials; composites designed to become highly dynamic in form and function. When subjected to certain environmental ques, like temperature or pressure, these smart materials can morph and adapt to new conditions. MIT, for instance, is working with self-transforming carbon fiber, printed wood grain, custom textile…

Magnetic Mirror reflects Light like No Other. Opens new suit of Optical Applications

In Lewis Caroll’s Through the Looking-Glass, and What Alice Found There (1871), the sequel to the classic Alice’s Adventures in Wonderland, Alice again enters a fantastical world, this time by climbing through a mirror into the world that she can see beyond it. Though far from Alice’s spectacular feat, scientists at the Sandia National Laboratories in Albuquerque, New Mexico demonstrated a new…

Developing smart cities: In the Spanish city of Santander, the walls will have ears

Image via Ear-It

Urban noise can be quite a nuisance, but it can also provide a lot of valuable information about the city’s needs. A first of its kind project in the city of Santander will check if this data can actually be used to improve the lives of citizens and develop a better, smarter city. “The EAR-IT project is an EU FP7 co-funded project…

This App Turns Your Phone Into A Cosmic Ray Detector

This is an artist's conception showing cosmic rays hitting the Earth. When they reach the Earth's atmosphere, the rays trigger showers of particles called air showers. In this illustration, the air showers are the branching, broom-tail portion of the rays. Simon Swordy, U. Chicago, NASA.

With a simple phone app you can donate your idle phone time to science; and if researchers decide to use this data in a paper, you’ll also be credited as an author. The app is called Cosmic Rays Found in Smartphones, or CRAYFIS – and all you have to do is download it, it takes care of the rest. What it does…
