KNOWLEDGE CAPSULE: A new kind of monkey

Scientists have identified a new species of African monkey whose colouring “is unlike anything I’ve ever seen,” as one of them put it.

Scientists have identified a new species of African monkey whose colouring “is unlike anything I’ve ever seen,” as one of them put it.

The monkey,known by people in the Democratic Republic of Congo as the lesula,has a blond chin and upper chest,in contrast to its dark limbs. It has a reddish-coloured lower back and tail.

“And adult males have a huge bare patch of skin in the buttocks,testicles and perianal area,” said John A. Hart,the researcher who described the colouring. “It’s a brilliant blue,really pretty spectacular.”

The researchers found that the monkeys live in Congo and have a range of about 6,500 square miles.

The first lesula seen by researchers was the pet of a schoolgirl. It bore a strong resemblance to another species,the owl-faced monkey,but the unusual colouring made the researchers suspect it was something new.

They were able to identify more lesulas in the wild and find hunters with specimens of the monkey. But John Hart warned,“Under the current trends of uncontrolled bush-meat hunting,it could become very endangered.”

Does adding milk to tea destroy its antioxidants?

Next to water,tea is the most widely consumed beverage in the world. Chock-full of antioxidants,vitamins and other compounds,tea has been linked in a variety of studies to stronger immune function and reduced cell damage. Some research suggests tea may prevent cavities,improve blood sugar levels and perhaps provide cardiovascular benefits.

In many parts of the world,the custom is to serve tea with milk. But lately researchers have been surprised to find that adding milk may strip tea of some of its beneficial effects.

In a study published in The European Heart Journal,researchers had 16 healthy adults drink cups of freshly brewed black tea,black tea mixed with a small amount of skim milk,or boiled water. Then the scientists measured the effects on vascular function.

Compared with water,black tea “significantly improved” arterial function,the researchers found,“whereas addition of milk completely blunted the effects of tea.”

A study published this year looked at whether the effect was limited to dairy products. It was not: Proteins in soy milk had the same effect as regular milk on antioxidants in tea.
