Media playback is unsupported on your device The secret life of the world's most trafficked mammal, the pangolin, has been caught on camera in Africa.Footage gives a rare insight into the behaviour of the giant pangolin, the largest of all the scaly animals.Observed by remote-operated cameras, a baby takes a ride on its mother's back, while an adult climbs a tree.Scientists are releasing the footage to highlight the plight of the animals, which are being pushed to extinction by illegal hunting for scales and meat.Large numbers of their scales have been seized this month alone, including Malaysia's biggest-ever interception of smuggled pangolin products.The images and video clips of giant pangolins, one of four species in Africa, were taken at ...
World's first tendril-like soft robot can curl and climb

World's first tendril-like soft robot can curl and climb

Science
Jan. 24 (UPI) -- Engineers in Italy have designed the world's first tendril-like soft robot. Like vines and other climbing plants, the slender, soft-bodied robot wraps itself around objects to pull itself higher and higher. The similarities are both external and internal. To hoist itself upward, the new robot relies on the same physical principles that govern water transport in plants. Water's movement through plant tissue is governed by the hydraulic principle of osmosis, which relies on the distribution of small particles throughout the cytosol, the liquid inside plant cells. Osmosis describes the movement of soluble particles from areas of lower to higher concentration across a semipermeable membrane. Mathematical models helped researchers at the Italian Institute of Technology replica...

World's rich grew by $2.5B a day in 2018 as poor's wealth dropped, Oxfam claims

Jan. 21 (UPI) -- The economic divide between the world's haves and have-nots widened last year, as the planet's billionaires saw their collective wealth increase by $ 2.5 billion a day while humanity's poorest half saw its wealth drop by 11 percent, a report published Monday by Oxfam showed. Published a day before the start of the World Economic Forum in Davos, Switzerland, the "Public Good or Private Wealth" report by the anti-poverty NGO states that the number of billionaires has almost doubled since the 2008 financial crisis while the world's corporations and super rich are "undertaxed." "Governments have been reducing both the top rate of personal income tax and the rate of corporate income tax over the long term," the report said, adding that if this were reversed, countries could af...
