Toroidal modeling of interaction between resistive wall mode and plasma flow. (arXiv:1305.3721v1 [physics.plasm-ph]):

Yueqiang Liu, Youwen Sun, arxiv.org

The non-linear interplay between the resistive wall mode (RWM) and the toroidal plasma flow is numerically investigated in a full toroidal geometry, by simultaneously solving the initial value problems for the n=1 RWM and the n=0 toroidal force…

Magnetic monopoles at the LHC and in the Cosmos. (arXiv:1305.3718v1 [hep-ex]):

P. Mermod, arxiv.org

The magnetic monopole was postulated in 1931 by Dirac to explain electric charge quantisation. Searches for pair-produced monopoles are performed at accelerator facilities whenever a new energy regime is made available. In addition, monopoles with…

On the performance of Usain Bolt in the 100 metre sprint. (arXiv:1305.3947v1 [physics.pop-ph]):

J.J. Hernández Gómez, V. Marquina, R.W. Gómez, arxiv.org

A theoretical model of the performance of the 100 m world record sprint of Usain Bolt during the 2009 World Championships at Berlin is developed, assuming a drag force proportional to $v$ and to $v^2$. The resulting equation of motion is solved an…

Quantum Limits of Interferometer Topologies for Gravitational Radiation Detection. (arXiv:1305.3957v1 [gr-qc])

Quantum Limits of Interferometer Topologies for Gravitational Radiation Detection. (arXiv:1305.3957v1 [gr-qc]):

Haixing Miao, Huan Yang, Rana X Adhikari, Yanbei Chen, arxiv.org

In order to expand the astrophysical reach of gravitational wave detectors, several interferometer topologies have been proposed to evade the thermodynamic and quantum mechanical limits in future detectors. In this work, we make a systematic…

After two years of searching, the icy observatory has finally found evidence of the high-energy particles, which may have come from a distant black hole or supernova.
It looks like the IceCube Observatory neutrino detector at the South Po…

Nasa captures the moment a meteor collides with the Moon
telegraph.co.uk

A meteoroid has hit the moon’s surface triggering a bright flash which was filmed by a Nasa telescope.
The meteoroid, which weighed an estimated 40kg (88lb), was travelling at 56,000 mph when it collided with the surface of the Moon…

FYI: Do Wind Farms Make It Less Windy?
By Daniel Engber, popsci.com

Related: Do they change the surrounding temperature?
Wind turbines extract kinetic energy from the air around them, and since less energy makes for weaker winds, turbines do indeed make it less windy. Technically speaking, the climate…

David Salisbury-VU, futurity.org

VANDERBILT (US) — Physicists may have created the smallest drops of liquid ever made in the lab—only the size of three to five protons. To provide a sense of scale, that is about one-100,000th the size of a hydrogen atom or one-100,000,000t…
