Archaeopteryx 'flew in bursts like a pheasant', scientists say

By
Archaeopteryx, one of life on Earth’s first stabs at building a bird, evaded predators and cleared obstacles on the ground by bursting into flight like a startled pheasant, a new analysis suggests.

High-resolution x-ray images of the creature’s skeleton reveal tell-tale similarities with the bones of birds that cannot glide or soar but instead take to the air in frenetic, flapping bounds, scientists say.

The findings add to a debate that has surrounded the Late Jurassic beast since the first fossilised remains were recovered from a limestone quarry in Bavaria in the 19th century. While Archaeopteryx definitely sported an elaborate plumage, how and even whether it flew was far from clear.

FIA’s Jean Todt defends Halo F1 system from ‘childish’ Toto Wolff criticism

By
The president of the FIA, Jean Todt, has issued a robust defence of his organisation’s decision to impose the Halo cockpit protection system on Formula One this season. Todt dismissed criticism from the Mercedes executive director, Toto Wolff, as “childish” and stressed that the FIA would not shy away from making difficult decisions in the interests of safety. The Halo device will make its race debut at the opening round in Melbourne but has attracted criticism on aesthetic grounds and because it is in contradiction of the spirit of an open-cockpit series.
