Nasa 'will need more astronauts'

Nasa does not have enough astronauts, even though the space shuttle programme has ended, a report says.
The National Research Council, a non-profit group advising on science policy, said Nasa should increase the size of its space-flying crew.
It said astronauts were needed to staff the International Space Station (ISS) and pave the way for new exploration.
American astronauts currently have to travel on Russian spacecraft in order to reach the ISS.
The US space shuttle programme ended in July, after 30 years.
'No flexibility' After many American astronauts retired or quit this year, there are only 60 left, down from a peak of 149 a decade ago.
Wednesday's report warns that Nasa's current projected astronaut corps size of 55-60 could pose a risk to crew replacements in case of illness or injury.
It said: "The committee concluded that the currently projected minimum staffing target size for the active astronaut corps poses a risk to the US investment in human spaceflight capabilities."
It added: "Given the range of potential crew assignment constraints and uncertainty in future requirements, the astronaut corps appears to be sized below the minimum required.
"The current plan for the size of the astronaut corps does not have the flexibility to accommodate commercial, exploration, and new mission development tasks, or unexpected increases in attrition."
The committee that worked on the report for Nasa was made up of 13 experts, including five former astronauts.
US astronauts currently fly on Russian Soyuz capsules to reach the ISS. A planned mission to the space station is on hold after a failed launch of cargo in August.
The station will become vacant temporarily at the end of November if Nasa cannot launch a new crew by then.

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...

Ancient Rakhine City of Mrauk-U Proposed for UNESCO World Heritage Site

The Irrawaddy YANGON—Myanmar’s Ministry of Religious Affairs and Culture submitted the final draft of its nomination for Mrauk-U to become a World Heritage Site to UNESCO on Monday, four months after the ministry submitted the first draft of its nomination in September 2019. If the application succeeds, Mrauk-U will be the third place in Myanmar to be inscribed as a UNESCO World Heritage Site, after the ancient cities of Bagan and Pyu. Mrauk-U is located in northern Rakhine State, around 60 km from the state capital of Sittwe. The ancient city was the seat of Arakanese kings from the 1400s until the late 1700s.

Much of the city’s remains are well-preserved and some 380 historic temples are scattered between the lush hills of northern Rakhine. Mrauk-U Heritage Trust chairwoman Daw Khin Than told The Irrawaddy on Tue...
