Searching for habitable exoplanets? Look for phosphorus

Scientists develop a new way to search for potentially habitable exoplanets by measuring the amount of phosphorus in their stars. Such planets should also have abundant phosphorus – necessary for life on Earth – increasing the chances for life.

Blue whales change their tune before migrating

(Cell Press) While parsing through years of recorded blue whale songs looking for seasonal patterns, researchers were surprised to observe that during feeding season in the summer, whales sing mainly at night, but as they prepare to migrate to their breeding grounds for the winter, this pattern reverses and the whales sing during the day. This finding, published October 1 in the journal Current Biology, may explain known inconsistencies in whale song patterns.

Ice Age manatees may have called Texas home

(University of Texas at Austin) Manatees don’t live year-round in Texas, but these gentle sea cows are known to occasionally visit, swimming in for a ‘summer vacation’ and returning to warmer waters for the winter. New research has found fossil evidence for manatees along the Texas coast dating back to the most recent ice age. The discovery raises questions about whether manatees have been visiting for thousands of years, or if ice age manatees once called Texas home.

How to stop global warming? The most controversial solutions explained – Eco-Business

Depending on who you ask, geoengineering is either a threat to serious climate action, a faraway back-up plan or a necessary part of today’s climate policy. All would likely agree it is contentious. Geoengineering encompasses a broad spectrum of proposed…

Greenland is on track to lose ice faster than in any century over 12,000 years

If human societies don’t sharply curb emissions of greenhouse gases, Greenland’s rate of ice loss this century is likely to greatly outpace that of any century over the past 12,000 years, a new study concludes. Scientists say the results reiterate the need for countries around the world to take action now to reduce emissions, slow the decline of ice sheets, and mitigate sea level rise.

New study reveals how reptiles divided up the spoils in ancient seas

While dinosaurs ruled the land in the Mesozoic, the oceans were filled by predators such as crocodiles and giant lizards, but also entirely extinct groups such as ichthyosaurs and plesiosaurs. Now for the first time, researchers have modeled the changing ecologies of these great sea dragons.

Watch for Mars and the full Harvest Moon

The Northern Hemisphere’s Harvest Moon is always the full moon falling the closest to the autumnal equinox. It’s coming up in 2020 on October 1 or 2. What’s more, this Harvest Moon will be near Mars!
