The European Space Agency’s Rosetta mission is currently exploring comet 67P/Churyumov-Gerasimenko, returning incredible views of this tiny frozen world. The Rosetta mission is a hugely ambitious endeavour – the first spacecraft to orbit a comet and follow it on its journey towards the Sun, accompanied by its lander, Philae, which made the first ever landing on a comet in November 2014. Observatories across the planet are supporting this mission, and the ING is playing an important part in this – especially in providing unique observations this year as the comet passed its closest point to the Sun and highest level of activity.
One of the key goals of the ground-based observation campaign that supports Rosetta is to understand the comet on the largest scales (the coma fills a volume tens of thousands of km across) while the spacecraft explores the very inner region (normally within 300 km of the 4 km long nucleus). To do this, observations need to look at both the shape of the coma via wide field imaging and the chemical composition of the coma gases. The gases reflect sunlight at different wavelengths, allowing them to be identified and measured using spectrograph instruments.

While the flux capacitor still conjures sci-fi images, capacitors are now key components of portable electronics, computing systems, and electric vehicles.

Iranian researchers from Tarbiat Modarres University designed a biosensor that enables the early diagnosis of leukemia in the test sample by using naked eyes. The biosensors have been produced at low cost, and they enjoy high sensitivity, selectivity and speed.

NASA, through its Jet Propulsion Laboratory (JPL) in Pasadena, California, has issued a call to American industry for innovative ideas on how the agency could obtain a core advanced solar electric propulsion-based spacecraft to support the Asteroid Redirect Robotic Mission (ARRM).

Quantum information can be sent optically, that is to say, using light, and the signal is comprised of photons, which is the smallest component (a quantum) of a light pulse. Quantum information is located in whichever path the photon is sent along -- it can, for example, be sent to the right or to the left on a semi-transparent mirror. It can be compared to the use of bits made up of 0s and 1s in the world of conventional computers. But a quantum bit is more than a classical bit, since it is both a 0 and a 1 at the same time and it cannot be read without it being detected, as it is only a single photon. In addition, quantum technology can be used to store far more information than conventional computer technology, so the technology has much greater potential for future information technology.

Airplane accidents are especially dangerous because jet fuel is highly flammable under crash conditions. On impact, jet fuel is dispersed in the air as a fine mist, which triggers a sequence of events that can lead to a fire engulfing an entire plane.

A nano-coil made of graphene could be an effective solenoid inductor for electronic applications, according to researchers at Rice University.

The secret is in a spiral form of atom-thin graphene that, remarkably, can be found in nature, according to Rice theoretical physicist Boris Yakobson and his colleagues.
