Asian elephants work out we’re paying attention to them by observing how our face and body are oriented: www.nature.com/articles/s41...

Two images sit side by side: one shows a TV screen with the word “Netflix” on it with a male viewer in the foreground and a brick wall in the background, while the other shows an advancing Asian elephant with vegetation in the background. Each has the caption: “big, long memory, knows when you’re watching”.

The mystery of medical diagnosis!

Anyone: Why are there suddenly so many AHDH diagnoses?
Dr. Jen: Same reason there are suddenly more stars after we built telescopes.

Big congratulations to Chunk for taking the crown as this year's #FatBearWeek winner! Today feels like as good a day as any to tell you all about a little trick that bears have to ensure pregnancy takes place during OPTIMAL FATNESS.

A very fat bear standing in a river. He is brown and furry, with a broken jaw which makes his tongue stick out.

Gustav Holst was the school music teacher of Cecilia Payne, who discovered the chemical composition of the stars. He tried to get her to become a musician but she ignored him. She went on to write the most important astrophysics PhD of the 20th century and become the first woman professor at Harvard

#classicalmusic #opera When I see "Gustav Holst" I can't help but wishing that he had stopped writing "The Planets" long before he got to Neptune. 🤮

#OTD 19 September 1991, walkers in the high Ötztal alps on the Italian border, found a body melting out of the ice. It turned out to be the remains of a c.5200 year old man preserved with all his kit.
Of course, it was essential to replicate him in Playmobil.

💫 Who taught us that the calcium in our bones and the iron in our blood were born in stars — and then fought to open observatories to women?

Born #OTD in 1919, Eleanor Margaret Burbidge changed both science and who gets to do it. 🔭🧪 #Astronomy #WomenInScience

Astronomical Society of the Pacific @astrosociety.org · Aug 12

Born #OTD in 1919 Margaret Burbidge helped reveal one of the great truths of the cosmos — that the atoms of life were forged in the hearts of stars. She then broke barriers to ensure women could study them.

We are made of starstuff & all deserve the chance to discover it. #Astronomy #WomenInScience

Some lives leave constellations in their wake.

Born on this day in 1919, Eleanor Margaret Burbidge helped reveal one of the great truths of the cosmos — that the atoms of life were forged in the hearts of stars. Her work on stellar nucleosynthesis, through the landmark B²FH paper, showed how hydrogen and helium became the oxygen we breathe, the calcium in our bones, the iron in our blood.

But Margaret’s legacy is not only written in the language of the stars. She fought to open observatory doors to women, challenged the limits society placed on who could do science, and inspired generations to follow curiosity wherever it leads.

Today, we remember not just her science, but her courage — and the truth she embodied: we are made of starstuff, and we all deserve the chance to discover it.

#Onthisday in 1888, Bertha Benz took the first ever long-distance car journey.

She solved snags as they arose, using a hat pin to clear a blockage, and replacing the brake blocks with leather, effectively inventing brake pads.

A crudely assembled image of an old motor car, which looks like little more than two bicycles with a seat in the middle, upon a background of a rolling German countryside with different trees. In the foreground is an autobahn sign along with another sign that reads “Nope no autobahn yet. Come back in 40+ years. Danke.”

Hahaha! This preprint! 🔭🧪

Chance of event happening to you or the planet, and if so, chance it will be lethal?

Turns out .... we are more likely to be hit by an impactor 140m and greater than:

- being struck by lightning
- getting killed by elephants and coyotes

arxiv.org/abs/2508.02418

Plot that shows a one-in-X chance of an event occuring to someone or the planet over a human lifetime on x-axis and then the one in X chance of a fatality if that event occurs. Several events are plotted such as contracting rabies, influenze, being hit by a car, being attacked by a coyote or elephant, being struck by lighting, carbon monoxide poisinging and the Earth being struck by an impactor greater than 140m in diameter

Controversial ‘arsenic life’ paper retracted after 15 years — but authors fight back

The journal Science retracts a headline-grabbing study, but the authors vigorously defend their data and say the retraction is unwarranted.

Painters often prime a canvas with a layer of white to make it smoother, stronger and to enhance the colours they will later layer on, but it seems this is a mechanism that birds were using long before humans picked up paintbrushes.

The secret to what makes colours pop on dazzling songbirds

Hidden layers of colour in the plumage of tanagers and some other songbirds explain what makes them so eye-catching
