>Don't be a 'hot-head'
Working in hot temperatures is already known to cause hyperthermia – a rise in body temperature – which can cause physical exhaustion.
But now scientists say prolonged exposure of the head to the sun also affects the brain's ability to function properly.
A study by university teams in Denmark and Greece provides evidence that direct exposure to sunlight – especially to the head – impairs motor and cognitive performance.
The decline in motor and cognitive performance was observed at 38.5 degrees.
Researchers said those exposed to sunlight for long periods should cover their heads.


>Couple spend lockdown in castle
A young British couple have spent coronavirus lockdown in a medieval castle with a spa, cinema, and 83 guest rooms.
Laura Jamieson and Michael Smith have been the sole occupants of an 800-year-old five-star hotel, Ashford Castle in Ireland, for nine weeks.
They moved into the castle when lockdown began to maintain its buildings and 350-acre estate until the time comes for tourists to be allowed to visit.
Laura said, "It's been surreal. We've been incredibly fortunate that we were able to have this experience."
But they admitted it's not all as glamorous as it may sound.
They are responsible for keeping the massive property clean - vacuuming, flushing 160 toilets and dusting chandeliers.



>'Mommy brain' does not last
"Mommy brain" is a long-held perception that mothers are more forgetful and less attentive.
"In most studies, however, attention and memory tests are given to mothers very early postpartum," said Valerie Tucker Miller, a PhD student in Purdue University's Department of Anthropology.
"There are a few issues with that," she added. "When you first have a child, you have a cascade of hormones and sleep deprivation that might be affecting attention and memory processes in the brain."
In a new study, Miller compared reaction times among 60 mothers, all of whom were at least one year postpartum, and 70 non-mothers.
The results show that mothers performed equally as well or better compared with women who had never been pregnant or had children.
"We wanted to see the long-term effects of maternity," Miller said. "Overall, moms did not have significantly different attention than non-mothers, so we did not find evidence to support 'mommy brain' as our culture understands it. It's possible, if anything, that maternity is related to improved, rather than diminished, attentiveness."

>Plastic straws to be phased out
The Shanghai-headquartered McDonald's China said on Tuesday that it has decided to phase out the use of plastic straws in China, which will reduce plastic consumption by an estimated 400 tons each year. Diners can enjoy cold drinks directly through McDonald's new type of cup lids. The new initiative has been launched in nearly 1,000 McDonald's outlets in Beijing, Shanghai, Guangzhou, and Shenzhen, starting from Tuesday, and is expected to cover other outlets across the Chinese mainland by 2020, the company said. McDonald's has been contributing to plastic reduction since 2007 by using paper takeout bags, paper McFlurry cups, and smaller cutlery.
