Colin discovered technology at an early age, pulling apart clocks, radios, and the family TV. Despite his father's remonstrations that he never put anything back together, Colin went on to become an electronics engineer. Later he decided to get a degree in anthropology, and used that to do all manner of interesting things masquerading as work. Even later he took up sculpting, moved to the coast, and never learned to surf.
Since first being synthesized by Andre Geim and Kostya Novoselov at the University of Manchester in 2004, there has been an extensive effort to exploit the extraordinary properties of graphene. However the cost of graphene in comparison to more traditional electronic materials has meant that its uptake in electronic manufacturing has been slow. Now researchers at the University of Glasgow have discovered a way to create large sheets of graphene at a fraction of the cost of current methods.
Of the many new exoplanets discovered over the past two decades, all have been identified as established, older planets. Some with incredible winds raging across their surfaceand others that may be able to support life because of their position in the habitable zone, but none have been acknowledged as newly-forming protoplanets. Now scientists working at the Keck observatory have spied just such a planet in the constellation of Taurus, some 450 light-years from Earth, that is only just beginning its life, collecting matter and spinning into a brand new world.
In what is being touted as the most complex and complete face transplant ever performed, a crew of medicos at New York University's (NYU) Langone Medical Center has replaced the entire face of 41-year-old Patrick Hardison, a volunteer firefighter who suffered catastrophic burns while on duty in 2001. The team replaced Patrick's scalp, ears and ear canals, parts of bone in the chin and cheeks, and his entire nose. He also received new eyelids and the muscles that control them.
Inspired by the water boatman bug, a team at the University of Bristol has created the Row-bot, a robot prototype that is designed to punt itself across the top of the water in dirty ponds or lakes, and "eat" the microbes it scoops up. It then breaks these down in its artificial stomach to create energy to power itself. In this way, it generates enough power to continuously impel itself about to seek out more bacteria to feed upon.
Prebiotic compounds that promote the growth of microorganisms, such as bacteria and fungi, can be traced back billions of years to their origins in the primordial goo – a rich soup of compounds from which all organic life on Earth is theorized to have begun. Now, scientists at Australia's CSIRO have discovered just how good a rich broth of these early molecules may be at improving the acceptance of implanted medical devices in the human body.
Looking more like a high-tech fighter than a light plane designed for private use, the Valkyrie from Cobalt aircraft has just been launched. With a canard front wing, sleek aerodynamic shape and a turbocharged 350 hp (260 kW) engine, the new Valkyrie is claimed to be capable of traveling at speeds of up to 260 knots (482 km/h, 300 mph) and has capacity for up to five adults and their luggage.
As energy production moves towards solar and wind-powered alternatives, battery systems to store intermittently-produced electricity have never been more important. Unfortunately, many of the materials needed to make high-performance batteries for this purpose are rapidly diminishing and becoming increasingly expensive as a result. Now researchers have created a new type of storage battery that is made from a range of cheap and abundant materials and shows promise for high-efficiency performance.
A new type of nanoparticle has been created by that converts invisible near-infrared light to higher energy blue and UV light with record-high efficiency. The multi-layered layered nanoparticle has potential for use in solar energy harvesting, bio-imaging, and light-based
Stealth aircraft like the F35 fighter generally rely on high-tech absorption materials and unusual geometries to scatter, deflect, and sponge up incoming radar signals. These techniques are exceptionally good at masking a vehicle's shape and size, particularly when swept with side-scanning radar. However, with lower-frequency, directed anti-stealth radar-targeting systems being developed, these surfaces prove much less able to hide an object. To help address this, a team of Chinese scientists has developed a thin electronic material that sheaths an object and effectively absorbs radar signals over a wide range of frequencies.
Wi-Fi connections are great when they work quickly and efficiently, but when they suddenly slow down inexplicably it can be very frustrating. Surprisingly, this isn't usually caused by a slow connection from your ISP, rather it occurs when two physically close Wi-Fi connections interfere with each other. Now researchers from the McCormick School of Engineering at Northwestern University have come up with a simple way to prevent this – and improve Wi-Fi speeds – by using Frequency Modulation (FM) and a smart time-sharing system that maximizes data throughput.
