Watched chimps change their hunting habits

Watched chimps change their hunting habits

Media playback is unsupported on your device Media captionNew insight into development of chimp hunting habitsChimpanzees in Uganda may have changed their hunting strategy in response to being watched by scientists. While studying the animals, researchers documented very different hunting habits of two closely neighbouring chimp “tribes”. “Sonso” chimps hunt in small groups for colobus monkeys, while those from the “Waibira” troop hunt solo and catch “whatever they can get their hands on”. The findings show how sensitive chimp society is to human presence. They are published in the journal…

India genome plan could boost healthcare

Image copyrightGetty Images Image caption Global Gene Corp wants data from people in under-represented regions, starting with South AsiaCould an effort to gather genetic data from its population of one billion people help India take the lead in advanced healthcare? India is the land of inventors and industry, spices and spirituality – and 1.3 billion human genomes. But although the subcontinent contributes around 20% of the world’s population, the DNA sequences of its people make up around 0.2% of global genetic databases. In a similar vein, 81% of the world’s…

Why suitcases rock and fall over – puzzle solved

Why suitcases rock and fall over – puzzle solved

Image copyrightGetty Images Image caption Speeding up, rather than slowing down, may prevent the suitcase flipping overIt’s a common experience when dashing for a train or plane while lugging a two-wheeled suitcase. The bag rocks alarmingly from side-to-side and threatens to overturn. Now, scientists have investigated this conundrum of everyday physics. Speeding up rather than slowing down can solve the problem, they say. Alternatively, you can pivot the handle of the suitcase as close to the ground as possible. French scientists studied a model suitcase on a treadmill to see…

Volcanoes 'triggered dawn of dinosaurs'

Volcanoes 'triggered dawn of dinosaurs'

Image copyrightScience Photo Library Image caption Scientists say intense eruptions took place 200 million years agoA million-year-long period of extreme volcanic activity most likely paved the way for the dawn of the dinosaurs, a study suggests. Scientists have analysed ancient rocks and have found traces of emissions from huge volcanic eruptions that happened about 200 million years ago. This would have led to one of the largest mass extinctions on record, enabling dinosaurs to become dominant. The study is published in the journal PNAS. Lead author Lawrence Percival, from the…
