Sanders seeks to cut $10 billion funding proposal for NASA’s new moon lander
US Senator Bernie Sanders has asked lawmakers to remove language from a bill that would fund the development of a new lunar lander for NASA, a move seen as part of the senator’s effort to cut federal funds that could go to companies owned by billionaire Jeff Bezos. The provision is part of a sweeping bill that would provide $52 billion in subsidies for semiconductor manufacturing and authorize additional funds to boost US competitiveness and scientific research.
A fifth of the world’s reptile species are threatened with extinction
About a fifth of reptile species – from the Galapagos tortoises to the Komodo dragon of the Indonesian islands, from the West African rhinoceros viper to the Indian gharial – are threatened with extinction, researchers said on Wednesday at the first overall assessment of reptile status. The study looked at 10,196 species of reptiles, including turtles, crocodilians, lizards, snakes and the tuatara, the only surviving member of a lineage dating back more than 200 million years. They found that 21% of species are critically endangered, endangered or vulnerable to extinction as defined by the International Union for Conservation of Nature (IUCN), the world’s authority on species status. They also identified 31 species that have already disappeared.

Fossils of giant marine reptiles discovered in the Swiss Alps
Fossils of some of the largest creatures to ever swim in Earth’s oceans – whale-sized marine reptiles called ichthyosaurs – have been discovered in a counterintuitive place: atop three mountains in the Swiss Alps up to 8,990 feet (2,740 meters) above sea level. Scientists on Thursday described fossil ribs and vertebrae of two ichthyosaur individuals: one about 69 feet (21 meters ) long and the other about 49 feet (15 meters). They described from a third individual the largest known tooth of any ichthyosaur with a base 2.4 inches (6 cm) wide and an estimated length of 6 inches (15 cm), suggesting a fearsome predator.
