It is not just humans who respond to motivational music. Researchers in the UK have discovered that blasting beats at zinc-oxide solar cells makes them perform up to 50% better. According to the researchers, pop and rock music gets the cells going more than classical music, but they suggest that any noise with a broad range of frequencies will produce similar effects. The discovery might be exploited by placing the devices on top of buses, air-conditioning units and in other noisy spots.

Does the Positron 'excess' really Exist?
The positron “excess” measured by two independent space missions and linked by some physicists to dark matter or pulsars does not exist, according to new theoretical work done by an international team of researchers. Instead, the researchers have calculated a "robust" upper limit for the positron flux created via interactions of high-energy cosmic rays with ambient gas in the galaxy and say that the flux measured by the Payload for Antimatter/Matter Exploration and Light-nuclei Astrophysics (PAMELA) experiment and the Alpha Magnetic Spectrometer (AMS) lies below this limit.
"Oh, Really?"
These Stories I used to Post on my 'Dark Matter' Blog or as a Propeller Hat Story when Posted Here on my General Blogger Postings.

How to watch a Bose–Einstein Condensate
for a Very Long Time
A new way of making measurements on Bose–Einstein condensates (BECs) has been
proposed by physicists in the UK and Australia. Calculations made by the team suggest that the technique could allow researchers to monitor BECs over much longer timescales than the several seconds possible today. If successfully implemented in the lab, the process could increase the use of BECs in practical applications such as atomic clocks and accelerometers.
A BEC is created by holding atomic gas in a magnetic trap and cooling the gas to nanokelvin temperatures
