Scientists have found remnants of small creatures in Antarctica under a deep layer of ice. The remains were found in mud that was brought up through a borehole. The findings might tell us something about the possibility of life on icy planets or moons
There is a growing global trend to consider pets as part of the family. In fact, millions of people around the world love their pets, enjoying their companionship, going for walks, playing and even talking to them. And there is evidence suggesting that attachment to pets is good for human health and even helps build community.
It’s been a good year for apples. Across Europe the apple harvest is the biggest it has been for a decade. But the handful of apple types you see on supermarket shelves only tells part of the story. There are actually 7,500 varieties of eating apple grown all over the world, and growers and scientists are making efforts to conserve and extend this.
As a graduate student in the 1970s, microbiologist Richard Blakemore probably wasn’t expecting to discover a new bacterial species with a never-before-seen ability. While studying bacteria that live in muddy swamps, he observed that some tended to swim reliably toward the same geographical direction. Even when he rotated the microscope, they persisted in wiggling toward one direction. After confirming that their swimming behaviors were unaffected by light, Blakemore suspected they might be responding to the weak magnetic fields naturally present on Earth.
Whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved. So wrote Charles Darwin, in his On the Origin of Species. The origin and evolution of animals is one of the most fascinating questions in modern biology.
The whale shark is the largest fish in the world, but much of its life cycle remains shrouded in mystery. These gentle giants gather in just a handful of places around the globe – something which has long baffled scientists – but our new research has started to explain why. Better understanding of whale shark movements could help prevent further population loss in a species that has already experienced a 63% population decline over the past 75 years.
