The humble honeybee can use symbols to perform basic maths including addition and subtraction, shows new research published today in the journal Science Advances.
Scientists who work with live organisms often have to move them between locations. This requires knowing what conditions creatures can tolerate well, and also can involve some unusual packing challenges. Here three researchers explain how they transport butterflies, sea turtles and endangered frogs safely between labs and the outdoors.
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.
