Australia’s ‘punk turtle’ on endangered list, risks being last of the Mohicans

Australia’s Mary River Turtle, which has green Mohican-style hair, was recently ranked 29th on the Zoological Society of London’s Evolutionary Distinct and Globally Endangered list, triggering calls for better protection of the reptile found in a remote part of Australia’s east coast.

A handout picture released by the Zoological Society of London (ZSL) on April 12, 2018, shows the Australian Mary River turtle, Elusor macrurus, a native of Queensland, Australia. Its distinctive hairdo is actually algae that grow on its head.(AFP/ ZSL / CHRIS VAN WYK)

Jesus Christ’s ‘crown of thorns’ tree may help fight climate change: Scientists

Researchers believe the Thorn Jujube is a “pioneer species” in the fight against desertification because its hardiness makes it resilient to rising temperatures and aridity. It also retains the ability to photosynthesise even when exposed to high temperatures and solar radiation

NASA to ‘read light’ in search for planets orbiting stars beyond solar system

NASA’s Transiting Exoplanet Survey Satellite, or TESS, will use a detection method called transit photometry, which looks for periodic, repetitive dips in the visible light from stars star caused by planets passing, or transiting, in front of them.

TESS, the Transiting Exoplanet Survey Satellite, is shown in this conceptual illustration obtained by Reuters on March 28, 2018. NASA plans to send TESS into orbit from the Kennedy Space Center in Florida aboard a SpaceX Falcon 9 rocket set for blastoff sometime between April 16 and June on a two-year mission.(Reuters)
