NASA will hold a news conference at 10 a.m. PST (1 p.m. EST) Wednesday, Feb. 22, to present new findings on planets that orbit stars other than our sun, known as exoplanets. The event will air live on NASA Television and the agency's website. Details of these findings are embargoed by the joual Nature until 10 a.m. PST (1 p.m. EST). Media and the public also may ask questions during the briefing on Twitter using the hashtag #askNASA. The briefing participants are: • Thomas Zurbuchen, associate administrator of the Science Mission Directorate at NASA Headquarters in Washington • Michael Gillon, astronomer at the University of Liege in Belgium • Sean Carey, manager of NASA's Spitzer Science Center at Caltech/IPAC, Pasadena, Califoia • Nikole Lewis, astronomer at the Space Telescope Science Institute in Baltimore • Sara Seager, professor of planetary science and physics at Massachusetts Institute of Technology, Cambridge A Reddit AMA (Ask Me Anything) about exoplanets will be

Thought your Inteet speeds were slow? Try being a space scientist for a day. The vast distances involved will throttle data rates to a trickle. You're lucky if a spacecraft can send more than a few megabits per second (Mbps). But we might be on the cusp of a change. Just as going from dial-up to broadband revolutionized the Inteet and made high-resolution photos and streaming video a given, NASA may be ready to undergo a similar "broadband" moment in coming years. The key to that data revolution will be lasers. For almost 60 years, the standard way to "talk" to spacecraft has been with radio waves, which are ideal for long distances. But optical communications, in which data is beamed over laser light, can increase that rate by as much as 10 to 100 times. High data rates will allow researchers to gather science faster, study sudden events like dust storms or spacecraft landings, and even send video from the surface of other planets. The pinpoint precision of laser

DNA replication is an extraordinarily complex multi-step process that makes copies of the body’s genetic blueprint. It is necessary for growth and essential to life. Now researchers at the Califoia Institute of Technology (Caltech) and Vanderbilt University have found evidence that one of those steps may involve the telephone-like transmission of electrical signals regulated by a chemical “switch.” Conventional telephones convert sound waves into electrical signals that can be transmitted vast distances through wire, and which are then converted back into audible sound at the receiving end. A similar form of communication may be required to achieve DNA replication. Only in this case the telephone wire is DNA and the telephones are unique clusters of four iron and four sulfur atoms within the multi-protein “machines” that copy it in a highly coordinated fashion. This model of replication has not yet been proven. But in a report published this week by the joua

Subject: Intl School on Hypercomplex Numbers, Lie Groups and Applications Dear Colleague, It is my pleasure to inform you about the Intl Summer School on Hypercomplex Numbers, Lie Groups, and Applications to be held in Vaa, June 9-12, 2017. For more detail, please visit the webpage of the meeting at http://www.bio21.bas.bg/conference/school Besides the Lectures Corses that will be delivered by the wellknown experts, there would be some slots for talks by the participants. We plan also to publish as a separate volume both the Lecture Courses and the contributed Talks before the end of this year. Registered participant will receive this volume for free. Details about the Registration are given on the webpage of the School. Please, notice that the School will be preceded by the XIX-th Edition of the aual Conference on Geometry, Integrability and Quantization which will take place in June 2-7, 2017. see http://www.bio21.bas.bg/conference Looking forward

Dear colleagues We would like to remind you about the summer school 'QCD Masterclass', that will take place on 18-24 of June 2017 in Saint-Jacut-de-la-Mer (west of France). The school is aimed in priority at Ph.D. students and postdocs in theoretical high energy physics, but senior researchers can also apply. All interested candidates should apply via the pre-registration form _before March 15, 2017_ at https://indico.ce.ch/event/547800/registrations/ The candidates are expected to apply for the complete duration of the school. Successful applicants will be notified shortly after the deadline for application. The registration fee is fixed to 400 euros and includes the full board accommodation from June 18 (evening) to June 24 (moing). The fee will be waived for selected participants from CNRS. The program of the QCD Masterclass consists in four topical lectures in QCD (~6-8 hours each) given from Monday to Friday. Topics and lecturers are: Resummation in QCD - Eric Laene

In the small affinity limit, the influence of an exteal white noise on the formation of Tsallis' velocity distribution function is studied through molecular dynamics simulation. The characteristic length of the noise is much smaller than the system size that causes a number of subs

The quantum structure of space-time at the Planck scale and quantum fields ,Sergio Doplicher, Klaus Fredenhagen, John E. Roberts (Submitted on 5 Mar 2003) We propose uncertainty relations for the different coordinates of space-time events, motivated by Heisenberg's principle and by Einstein's theory of classical gravity. A model of Quantum Space-time is then discussed where the commutation relations exactly implement our uncertainty relations. We outline the definition of free fields and interactions over QST and take the first steps to adapting the usual perturbation theory. The quantum nature of the underlying spacetime replaces a local interaction by a specific nonlocal effective interaction in the ordinary Minkowski space. A detailed study of interacting QFT and of the smoothing of ultraviolet divergences is deferred to a subsequent paper. In the classical limit where the Planck length goes to zero, our Quantum Spacetime reduces to the ordinary Minkowski spac
