Tackling coral reefs’ thorny problem: Crown-of-thorns starfish

Researchers have revealed the evolutionary history of the crown-of-thorns starfish — a predator of coral that can devastate coral reefs. Their findings shed light on how the populations of these starfish have changed over time and could potentially help reduce their ecological destruction.

The battle to stop global warming is increasingly being fought in the courtroom – The Japan Times

LONDON/WASHINGTON/GENEVA – Climate change may be having its day in court. With the slow pace of international climate negotiations, lawyers from Switzerland to San Francisco are increasingly filing lawsuits demanding action. And they are getting creative — using new legal…

Mini-‘Marsquakes’ measured by InSight lander show effects of sun and wind

(Kyushu University, I2CNER) Analysis of seismometer data from the InSight Martian lander revealed that different types and frequencies of ambient low-magnitude “microtremors” on Mars were associated with different sources, and some reflected daily variations in wind and solar irradiance, either in distant locations or near the lander. These findings will contribute to future projects seeking to model and monitor the Martian subsurface.

A shake-up in cell culturing: Flame sterilization may affect the culture

(University of Tsukuba) Researchers from the University of Tsukuba have found that flame-sterilizing shake-flasks, to avoid introducing microbial contaminants, considerably increases the carbon dioxide concentration in the flasks. This enhanced carbon dioxide concentration affects the growth of some microbial species, which may affect the quantity of vaccines or other valuable substances produced by the microbes.

Bleaching affects aquarium corals, too

(ARC Centre of Excellence for Coral Reef Studies) A world-first study examines the temperature thresholds of Australian aquarium corals and finds they are at risk under climate change.

Tiny Japanese dinosaur eggs help unscramble Cretaceous ecosystem

A research team has excavated over 1300 eggshell fossils from the Lower Cretaceous Ohyamashimo Formation of Hyogo Prefecture, Japan. Over 96% of these fossils, including numerous fragments, four partial and almost complete eggs in an in situ nest, belonged to a new ootaxon the authors named Himeoolithus murakamii, attributed to a small non-avian theropod dinosaur. The remaining eggshell fragments, belonging to five additional small theropod ootaxa, showed notable biodiversity.
