Scottish invention 'improves phone storage'

Scottish researchers have helped to create a device which improves memory storage for technology including MP3s, smartphones and cameras.
The device uses a tiny mechanical arm to translate data into electrical signals.
This allows faster operation and uses less energy compared with conventional memory storage products.
The Edinburgh University researchers worked with the Konkuk University and Seoul National University, in Korea.
The device records data by measuring the current passing through a carbon nanotube, and the binary value of the data is determined by an electrode that controls the flow of current.
Previous attempts to use carbon nanotube transistors for memory storage hit a stumbling block because they had low operational speed and short memory retention times.
By using a mechanical arm to charge the electrode, which operates faster than conventional memory devices, scientists have been able to overcome the problems.
'Novel approach' Prof Eleanor Campbell, from Edinburgh University's school of chemistry, said: "This is a novel approach to designing memory storage devices.
"With this device you have much faster switching on and off which you do not have with conventional memory storage devices.
"However, one of the issues with these novel devices is how easy they can be manufactured on an industrial scale, which we are yet to see."
Prof Campbell said research was continuing with colleagues in Korea on increasing the operating speed of the device even further.
The findings were published in the journal Nature Communications.

Chronology of the Press in Burma

1836 – 1846 * During this period the first English-language newspaper was launched under British-ruled Tenasserim, southern  Burma . The first ethnic Karen-language and Burmese-language newspapers also appear in this period.     March 3, 1836 —The first English-language newspaper,  The Maulmain Chronicle , appears in the city of Moulmein in British-ruled Tenasserim. The paper, first published by a British official named E.A. Blundell, continued up until the 1950s. September 1842 —Tavoy’s  Hsa-tu-gaw  (the  Morning Star ), a monthly publication in the Karen-language of  Sgaw ,  is established by the Baptist mission. It is the first ethnic language newspaper. Circulation reached about three hundred until its publication ceased in 1849. January 1843 —The Baptist mission publishes a monthly newspaper, the Christian  Dhamma  Thadinsa  (the  Religious Herald ), in Moulmein. Supposedly the first Burmese-language newspaper, it continued up until the first year of the second Angl

ARSA claims ambush on Myanmar security forces

Arakan Rohingya Salvation Army (ARSA) on Sunday claimed responsibility for an ambush on Myanmar security forces that left several wounded in northern Rakhine state, the first attack in weeks in a region gutted by violence. Rakhine was plunged into turmoil last August, when a series of ARSA raids prompted a military backlash so brutal the UN says it likely amounts to ethnic cleansing of the Muslim Rohingya minority. The army campaign sent some 650,000 Rohingya fleeing for Bangladesh, where refugees have given harrowing accounts of rape, murder and arson at the hands of security forces and vigilantes. Myanmar's military, which tightly controls information about Rakhine, denies any abuses and insists the crackdown was a proportionate response to crush the "terrorist" threat. ARSA have launched few attacks in recent months.  But the army reported that "about ten" Rohingya terrorists ambushed a car with hand-made mines and gunfire on Friday morning

Thai penis whitening trend raises eyebrows

Image copyright LELUXHOSPITAL Image caption Authorities warn the procedure could be quite painful A supposed trend of penis whitening has captivated Thailand in recent days and left it asking if the country's beauty industry is taking things too far. Skin whitening is nothing new in many Asian countries, where darker skin is often associated with outdoor labour, therefore, being poorer. But even so, when a clip of a clinic's latest intriguing procedure was posted online, it quickly went viral. Thailand's health ministry has since issued a warning over the procedure. The BBC Thai service spoke to one patient who had undergone the treatment, who told them: "I wanted to feel more confident in my swimming briefs". The 30-year-old said his first session of several was two months ago, and he had since seen a definite change in the shade. 'What for?' The original Facebook post from the clinic offering the treatment, which uses lasers to break do
