Award-winning photographer Josh Dury captured this stunning picture of the Milky Way over Easter Island and some of its famous Maoi. From his Instagram post: "A truly unforgettable night from one of the darkest places on Earth, surrounded by a place and a community that is close to my heart. One of the most powerful, emotional moments of my life."

Research on how bacteria and archaea interact with other members of the plankton food-web is much more advanced in #ocean systems compared to freshwaters, but still very much unknown. They are food, but we also know of many cases of apparent symbiosis between #bacteria and organisms, with bacteria providing bioluminescence, energy via photosynthesis, or B vitamins, but how common is this?

Just finished this biography of George Beadle, written by Paul Berg and Maxine Singer. Rare to find a biography of an amazing scientist written by two other very accomplished scientists.
Lots of fascinating stories about early genetics research.
There are many valid reasons to be skeptical of geoengineering & still a lot of opportunities to address #ClimateChange that don’t involve the uncertainty of tinkering with the planet.
Lumping geoengineering skepticism with conspiracy theorists in a headline is terrible framing.

A newly discovered bacterium, Uabimicrobium helgolandensis, eats other bacteria and is a kind of 'bacteria of prey,' that should not even exist based on previous concepts about microbial cells. It could be a kind of microbial missing link, researchers suggest.

#PPOD: This stunning photograph captures the most violent moment during an eruption of the Calbuco volcano in Chile. Volcanic lightning occurs in the plumes of eruptions when volcanic ash particles collide, generating static electricity. Additionally, water vapor in the plume condenses and freezes as it rises, adding ice to the mix. And voila! The eventual electrical discharge causes lightning.

A team of scientists from the University of Bristol recently released research that pushed the date of our Last Universal Common Ancestor (LUCA) back to about 4.2 billion years ago.
This suggests that the life that is in each of us, and in each of the organisms that make up our very large extended family, runs in an unbroken chain backward for 4.2 billion years.
That’s a pretty considerable investment by the universe in every living thing.
Perhaps we should reflect on that a little more as we continue to muck around on this planet.
It might be time to start fitting in.

#Copepod #zooplankton are the most numerous metazoans on the planet, and some have evolved into fantastical forms. Take Calocalanus pavo, the beautiful "peacock copepod", which has amazingly plumed antenna and caudal rami. It is small, ~1mm long, and uses the plumes to slow its sinking for feeding in the upper #ocean. It is famous for being very prominent in Ernst Haeckel's Kunstformen der Natur (1904) plate 54 #watercolour paintings of copepoda.

But with statements like “This time of year, managing heat is on everyone’s mind.” you have to wonder.

Born in 1805 in Jamaica, Mary Seacole was a pioneering nurse.
As a child, Mary learned traditional healing methods from her mother. Her mixed race family had few civil rights & could not vote, hold public office or enter many professions.
Known as 'Mother Seacole’ during the Crimean War, Mary helped wounded soldiers heal & find comfort.
In 1857, she published her memoirs, 'The Wonderful Adventures of Mrs Seacole in Many Lands'. https://www.maryseacoletrust.org.uk/learn-about-mary/ #HistoryRemix #history #science

Latest comic: The Supreme Court ruling overturning the Chevron doctrine was largely overlooked in the wake of the debate, but possibly even more apocalyptic.
