Some mind-boggling details of a Martian impact crater taken by NASA's HiRISE camera onboard the Mars Reconnaissance Orbiter. This image has everything: layers, boulders, dunes, and maybe some polygonal terrain, too. The blue filter is used here to learn about morphologies, textures, and composition.
What’s the big deal about tiny devices like springs and screws? This week, Roma Agrawal shows us how the world as we know it couldn’t function without these simple, but ingenious, objects. It’s “Nuts and Bolts” on Big Picture Science.
#PPOD: This artist's concept illustrates Kepler-16b, the first planet known to definitively orbit two stars -- what's called a circumbinary planet. The planet, which can be seen in the foreground, was discovered by NASA's Kepler mission. The two orbiting stars regularly eclipse each other, as seen from our point of view on Earth.

Wie viel Wissenschaft steckt in der Netflix-SciFi-Serie "3 Body Problem"? Darüber habe ich gestern Abend drei Stunden lange mit Dr. Lisa Ringena von IsoQuant Heidelberg & @nawik und Cedric Engels aka Doktor Whatson bei ARTE #Couchwissen gesprochen.

A research team using the ChemCam instrument onboard NASA’s Curiosity rover discovered higher-than-usual amounts of manganese in lakebed rocks within Gale Crater on Mars, which indicates that the sediments were formed in a river, delta, or near the shoreline of an ancient lake. The results were published today in Journal of Geophysical Research: Planets.
"You know the toxic dust that you’re talking about? That’s my scientific research."
From October 2023. Cluster member and University of #Utah-based Kevin Perry talks about work studying the shrinking Great Salt Lake with Science Friday.
#PPOD: Rising from turbulent waves of dust and gas is the Horsehead Nebula, Barnard 33, which resides roughly 1,300 light-years away, and the NASA/ESA/CSA James Webb Space Telescope has captured the sharpest infrared images to date. Webb’s new view focuses on the illuminated edge of the top of the nebula’s distinctive dust and gas structure. Credit: NASA, ESA, CSA, K. Misselt (University of Arizona) and A.

We are still in 2004. Here is a coloured sketch of a megaraptorid walking into the ribcage of an eaten titanosaur. The predator is reflected in a pond of blood. Oh, and I know the sickle-claw shouldn't be there (I was making quite a few mistakes back in 2004).
It covers everything from the history of scicomm to press releases, #SocialMedia, #science shows, risk communication, engaging with policy makers, language, you name it... Highly recommended!

In 2004 I played with a book idea but never took it to a publisher. I did 100 draft drawings for the proposal (never completed), here is just one more: Spinosaurus (old anatomical proportions) eating a Carcharodontosaurus.

In 2004 I played with a book idea but never took it to a publisher. I did 100 draft drawings for the proposal (never completed), I'll post a few more throughout today. Third is Carcharodontosaurus playing with a baby sauropod.

We're thrilled to share that undergraduate Param Joshi from NIT Rourkela, India, collaborating with Dr. Vishal Gajjar and a team of researchers at the Allen Telescope Array of the SETI Institute, has led the discovery of a Fast Radio Bursts with the widest bandwidth. After meticulously analyzing over 200 hours of observations with a specialized machine learning algorithm, Param successfully identified eight Fast Radio Bursts.
Some Narrative Conventions of Scientific Discourse
Rom Harré, 1990
"The academic ‘we’ might seem at first glance to be just a version of the editorial ‘we’. Like the latter it is mutedly egocentric but it is not mainly used to imply teamwork. Rather, it is used to draw the listener into complicity, to participate as something more than an audience. "
"The moral status of persons determines the epistemic status of their results. This becomes entirely intelligible if we think in terms of trust rather than truth. Trust in someone’s results depends very much on our faith in that person, whereas truth, so it seems to me, ought to be tied to trust in a methodology, regardless of who uses it, provided they use it competently. " - Harré p 93.
