Species make comeback 30 years after rainforest devastation

Rainforest loss is fuelling a tsunami of tropical species extinctions. However, not all is doom and gloom.

A new study, conducted in the Brazilian Amazon, suggests that ecological cataclysms prompted by the fragmentation of the forest can be reverted by the regeneration of secondary forests, offering a beacon of hope for tropical forest biodiversity across the...

DNA study of cow stomachs could aid meat and dairy production

Meat and milk production from cattle could one day be boosted, thanks to analysis of microbes in cows' stomachs.

The study paves the way for research to understand which types of microbe -- such as bacteria -- are best at helping cattle to extract energy from their food, experts say.

It also identifies enzymes that are specialised...

Tracking endangered mammals with the leeches that feed on them

A broad survey conducted across southern Asia reinforces the idea that the mammal biodiversity of an area can be determined by looking at the DNA found in leeches' blood meals. The new study, led by researchers at the American Museum of Natural History, also shows for the first time that DNA found in leeches can...

Antimicrobial resistance in zoonotic bacteria still high in humans, animals and food

Bacteria from humans and animals continue to show resistance to antimicrobials, according to a new report published today by the European Food Safety Authority (EFSA) and the European Centre for Disease Prevention and Control (ECDC). The report highlights some emerging issues and confirms antimicrobial resistance (AMR) as one of the biggest threats to public health....
