Research released this week supports the House of Commons vote to make all workplaces smoke free, including pubs and bars.
A team of researchers visited 64 pubs across the north west of England. They measured air quality using a portable monitor for at least 30 minutes in an area of the pub where smoking was allowed. They found very poor air quality with high levels of particles (PM2.5), particularly in pubs serving more deprived populations. These particles are breathed into the lungs and have been associated with harm to health in humans.
There is no UK air quality standard for PM2.5 particles. However, the average particle levels observed, particularly in pubs serving deprived populations, were well above levels which the US Environmental Protection Agency labels as ‘very unhealthy’ and ‘hazardous’. Average levels of particles in the pubs were about ten times higher than those typically found next to heavily trafficked roads in the UK and in four pubs were about 40 times higher.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.
The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
