>Post-Covid-19 fatigue investigated
Most people experience COVID-19 as a short-term illness: Once the infection has been fought off, they bounce back to health.
But evidence is emerging of a significant minority who struggle with long-term fatigue syndrome for a month or longer.
Scientists are only just beginning to investigate the potential causes of enduring fatigue, but say that there are likely to be a wide variety of reasons why some people face a longer road to recovery.
Those who have suffered severe illness in the acute phase, including admission to intensive care, typically experience muscle loss, which can result in direct physical fatigue.
Others are left with lung damage, including scarring that can cause breathlessness, leaving people feeling tired.
A study taken by Chris Brightling, a professor of respiratory medicine at the University of Leicester, will track about 10,000 patients who were admitted to the hospital with COVID-19.
This will allow scientists to assess what proportion of patients end up with which long-term health impacts, and what the risk factors are for different symptoms.
>First gold-plated hotel opens
Dolce Hanoi Golden Lake, the world's first self-proclaimed gold-plated hotel, is open for business in Vietnam - and its owners insist they have the Midas touch despite the cramping of global travel during the coronavirus pandemic.
The hotel cost $200 million to construct with 24-carat plating across lobbies, an infinity pool and rooms with even cutlery, cups, shower heads and toilet seats receiving the golden treatment.
While expensive for ordinary Vietnamese at $250 a night, it is not prohibitive for wealthy locals craving a guilty pleasure.
>Red light can boost eyesight
A few minutes of looking into a deep red light could have a dramatic effect on preventing eyesight decline as we age, according to a new study published this week in The Journals of Gerontology.
The science works, said Glen Jeffery, a professor of neuroscience at University College London's Institute of Ophthalmology, because the light stimulates the health of mitochondria, which are like batteries in our cells.
And because mitochondria are implicated in a broad range of diseases, insights like these could help lead to new treatments for diseases, including Parkinson's and diabetes.
"The retina ages faster than any other organ in your body," Jeffery said. "From an evolutionary perspective, we fundamentally have never lived past 40."
Now, of course, we regularly live well beyond that age, and need ways to nurture the organs that for millennia have been the most likely to wear out earliest in life.
>UK offers discount for eat-out
Britain launched a $625 million "Eat out to help out" discount strategy to boost spending at restaurants, cafes and pubs that have been crippled by COVID-19, offering half-priced meals from Monday to Wednesday to get people spending again.
For the month of August, the scheme will entitle diners to a 50 percent discount of up to 10 pounds per head on their meal, Finance Minister Rishi Sunak said. The discount can be used unlimited times in August.
But it will not apply to alcohol.
Sunak also announced a temporary cut in VAT sales tax from 20 percent to 5 percent for eat-in or hot takeaway food from restaurants, cafes and pubs.
