Researchers discover 4 new walking sharks
[embedded content] “Jaws” portrayed sharks as man-hunting villains. “Sharknado” imagined a world where they attack from twisters. But in the real world, sharks are much more complex. Now, researchers have discovered new species of sharks that have evolved to walk,…
Doomsday Climate Predictions: Wrong Then, Wrong Now
How many doomsday predictions about the Earth’s climate must fail before they finally get broadly ignored and dismissed out of hand? Considering the track record of climate predictions that turned out to be false, we are well passed the moment…
Cyanobacteria in water and on land identified as source of methane
(Forschungsverbund Berlin) Cyanobacteria, also known as blue-green algae, are among the most common organisms on Earth. A research team led by the Leibniz-Institute of Freshwater Ecology and Inland Fisheries and Heidelberg University has now shown for the first time that Cyanobacteria produce relevant amounts of methane in oceans, inland waters and on land. Due to climate change, “Cyanobacteria blooms” increase in frequency and extent, amplifying the release of methane from inland waters and oceans to the atmosphere.
Like Adding ‘Five to Six Hiroshima Bombs of Heat Each Second,’ Study Shows Oceans Warming at Record Rate – Common Dreams
A new study published Monday shows that the Earth’s oceans reached the highest temperatures and warmed the fastest since records began, highlighting the urgent need for global action to address the climate crisis before it’s too late. The study (pdf),…
The advantage of changing sex in fish population recovery
Some fish species recover at different rates when fishing is eliminated inside MPAs. A new study explores how sex-changing fish species can actually recover faster than fixed-sex species.
Lethal algae blooms – an ecosystem out of balance
On 3 August 2014, residents of Toledo, Ohio, woke to the news that overnight their water supply had become toxic. They were advised not only to avoid drinking the water, but also touching it – no showers, no baths, not…
Climate change: The devastation of Australia’s ocean – The Independent
Even before the ocean caught a fever and reached temperatures no one had ever seen, Australia’s ancient giant kelp was cooked. Rodney Dillon noticed it the day he squeezed into a wet suit several years ago and dove into Trumpeter…
eDNA expands species surveys to capture a more complete picture
(NOAA Fisheries West Coast Region) Tiny bits of DNA collected from waters off the West Coast allowed scientists to identify more species of marine vertebrates than traditional surveys with trawl nets. They also reflect environmental shifts such as unusual ocean temperatures that affect the organisms present, new research shows.
Why you need to limit artificial light at night
It’s incredibly hard to sleep when light seeps through your curtains or your phone glows from the bedside table. But more and more research is finding that artificial light may be more than annoying. It can be seriously unhealthy, too….
