Since the late Pleistocene, large-bodied mammals have been extirpated from much of Earth. Although all habitable continents once harbored giant mammals, the few remaining species are largely confined to Africa. This decline is coincident with the global expansion of hominins over the late Quaternary. Here, we quantify mammalian extinction selectivity, continental body size distributions, and taxonomic diversity over five time periods spanning the past 125,000 years and stretching approximately 200 years into the future.

NAIROBI (Xinhua) -- The Kenyan government said Tuesday it has resorted to science to help improve its national forest cover.

The African Academy of Sciences (AAS) on Wednesday launched a platform to help showcase cutting edge research that is addressing endemic challenges in the continent like diseases, hunger and climat

The present study documents the wood-boring trace fossil Asthenopodichnium from the Palaeocene sediments of the Barmer Hill Formation (BHF) in the Barmer Basin, Western Rajasthan, India. The Asthenopodichnium trace fossils are loosely to tightly packed, pouch-like burrows or almond-shaped structures identified as Asthenopodichnium lignorum, whereas lozenge and J-shaped structures are designated as Asthenopodichnium lithuanicum.

Potential risks of supply shortages for critical metals including rare-earth elements and yttrium (REY) have spurred great interest in commercial mining of deep-sea mineral resources. Deep-sea mud containing over 5,000 ppm total REY content was discovered in the western North Pacific Ocean near Minamitorishima Island, Japan, in 2013. This REY-rich mud has great potential as a rare-earth metal resource because of the enormous amount available and its advantageous mineralogical features.

India’s science and technology policies advocate increased investment in research and development. However, in 2017–18, the tax incentive for company expenditure on R&D was reduced. This is likely to have major ramifications for R&D at a time when India’s domestic research effort is already in decline.

This publication takes forward the 12 action points adopted at the First Asian Science and Technology Conference for Disaster Risk Reduction (ASTCDRR) as a contribution to the global ‘Science and Technology Roadmap’.

Dutch astronomers and ecologists are working with Leiden University on a project, MONOCLE, that allows people to measure the quality of their water, simply by taking a photo with their smartphones.

Pterosaurs were winged cousins of the dinosaurs and lived from around 200 million years ago to 66 million years ago, when the last pterosaurs disappeared during the Cretaceous-Paleogene extinction that wiped out the dinosaurs. The pterosaurs are thought to have declined in diversity before their final extinction, suggesting that gradual processes played a major role in their demise. However, pterosaur fossils are very rare, and thus, it is unclear whether pterosaurs were really low in diversity at this time or whether these patterns merely result from a paucity of fossils.
