A big step toward producing rhino gametes

To save the northern white rhinoceros from extinction, the BioRescue team is racing to create lab-grown egg and sperm cells of the critically endangered subspecies. The team has now reported a milestone in Science Advances: they have generated primordial germ cells from stem cells – a world’s first. Thirty-three-year-old Najin and her daughter Fatu are the […]

Sound reveals ‘Ocean giants’ dance with wind to find food

A study by MBARI researchers and their collaborators published today in Ecology Letters sheds new light on the movements of mysterious, endangered blue whales. The research team used a directional hydrophone on MBARI’s underwater observatory, integrated with other advanced technologies, to listen for the booming vocalizations of blue whales. They used these sounds to track the movements […]

Clarifying the chaos of narwhals behavior; what are narwhals, how they help [Details]

Researchers have used the mathematical equations of chaos theory to analyse the data from long-term monitoring of an electronically tagged narwhal. They have extracted previously undetected diurnal patterns within what initially appeared to be irregular diving and surface resting behavior, using records extending across 83 days. “While animal-borne ocean sensors continue to advance and collect […]

More than 1.1 million sea turtles poached over last three decades: Study

One of the most serious threats to wildlife biodiversity, in addition to the climate crisis, is the illegal killing and trafficking of animals and plants. Despite many laws against the black-market wildlife trade, it is considered to be one of the most lucrative illicit industries in the world. Animals, especially endangered and threatened species, are […]

Crocodiles Set to Face Extinction, Says Australian Researcher

Many of the world’s 27 species of crocodylians will soon be either totally or locally extinct due to human population expansion and intensive land-use for agriculture depleting the water bodies, which provide succour to crocs, said a University of Queensland researcher. Emeritus Professor Gordon Grigg of UQ says the fact that these reptiles had survived millions […]
