Saturn’s moon Dione harbors a subsurface ocean

more »
A subsurface ocean lies deep within Saturn's moon Dione, according to new data from the Cassini mission to Saturn. Two other moons of Saturn, Titan and Enceladus, are already known to hide global oceans beneath their icy crusts, but a new study suggests an ocean exists on Dione as well.

Hidden stars revealed by dustbuster

more »
In a new image captured by the nebula Messier 78, young stars cast a bluish pall over their surroundings, while red fledgling stars peer out from their cocoons of cosmic dust. To our eyes, most of these stars would be hidden behind the dust, but ESO's Visible and Infrared Survey Telescope for Astronomy (VISTA) sees near-infrared light, which passes right through dust. The telescope is like a giant dustbuster that lets astronomers probe deep into the heart of the stellar environment.

2-D boron may be best for flexible electronics

Though they're touted as ideal for electronics, two-dimensional materials like graphene may be too flat and hard to stretch to serve in flexible, wearable devices. "Wavy" borophene might be better, according to scientists.

Ukraine becomes an associate member of CERN

Today, Ukraine becomes an associate member State of CERN. This follows official notification to CERN that Ukraine’s Parliament has ratified the agreement, signed with CERN in October 2013.

"Our hard and consistent work over the past two decades has been crowned today by a remarkable event - granting Ukraine the status of CERN associate member. It is an extremely important step on the way of Ukraine's European integration," said Yurii Klymenko, Ukraine’s Ambassador to the UN in Geneva.

"It is a great pleasure to warmly welcome Ukraine into the CERN family. The laboratory has worked closely with Ukrainian colleagues over many years, and we look forward to strengthening this collaboration in the framework of associate membership," said CERN Director General, Fabiola Gianotti.

Ukraine and CERN signed a cooperation agreement in 1993, and a joint declaration in 2011, setting priorities in scientific-technical cooperation. Ukraine’s relationship with CERN dates back much further, principally through CERN’s cooperation with the Joint Institute of Nuclear Research (JINR) in Dubna, Russia, of which Ukraine is a member.

Ukraine has been a long-time contributor to the ALICECMS and LHCb experiments at the LHC, and to research and development on new accelerator technologies. Ukraine also operates a Tier-2 computing centre in the World-wide LHC Computing Grid (WLCG) to help to process and analyse the massive amounts of data generated by the LHC experiments.

The associate membership of Ukraine strengthens the long-term partnership between CERN and the Ukrainian scientific community. Associate membership allows Ukraine to participate in the governance of CERN, through attending the meetings of the CERN Council. It also allows Ukrainian scientists to become members of CERN staff, and to participate in CERN’s training and career-development programmes. Finally, the Ukrainian industry can now bid for CERN contracts, thus opening up opportunities for industrial collaboration in areas of advanced technology.

New classes of electron orbits discovered

more »
Phenomena like solar flares and auroras are consequences of magnetic reconnection in the near-Earth space. These "magnetic reconnection" events are akin to magnetic explosions that accelerate particles as they rapidly change the topology of the magnetic field lines. Researchers have used a new Particle-In-Cell (PIC) simulator to understand how magnetic reconnection works for the tenuous plasma surrounding our Earth and have identified new classes of electron orbits that help scientists understand the characteristics of the fast jets of electrons that stream from the reconnection region.
