Lovely examples of how BUTTONS used to be made from the nacreous layer of these bivalves! Just take "hole punches" through the shells! #molluscmonday

Clams + other inverts can serve as records of temperature and salinity, via ratio of oxygen-18 and 16 in their shells. A new study uses records from ocean quahogs and bittersweet clams to show that Atlantic overturning current may be reaching a climate tipping point (290) bsky.app/profile/cezz...

Tiny fossils called foraminifera lie buried in marine sediments.
Their shells display astonishing diversity from spiraling forms to chambered clusters and even architectures that resemble miniature buildings.
But what if this morphological variety could be explained by only a few simple rules? 1/n

It has now been 2 years since my book, Microbiology for Earth Scientists, was published online. It has been downloaded in over a hundred countries worldwide! Very happy to see that it is being found and hopefully serving as a helpful resource! #openaccess

Microbes are collectively one of the biggest forces shaping Earth, and yet undergraduate #geology students typically receive little training in microbiology. My new open access textbook seeks to help. “Microbiology for Earth Scientists” is freely available here newprairiepress.org/ebooks/53/

“..NSF has only allowed students to apply once during graduate school, and many are given advice to wait until their second year when their applications will be stronger.”

I have a student who waited. It is competitive and a long shot, but being able to try still matters.

Science Magazine @science.org · 12d

NSF today released instructions for the next round of applicants to its Graduate Research Fellowship Program. A key group—second-year Ph.D. students—is no longer eligible, and students who are still able to apply will face an unusually narrow timeframe. https://scim.ag/3KlQkQk

‘Completely shattered.’ Changes to NSF’s graduate student fellowship spur outcry

The announcement comes months later than usual, leaving many would-be applicants stranded

Announcing such a major change to NSF GRFP this late in the cycle is incredibly cruel. 2nd yr students (mine included) have been working so hard on their proposals despite ongoing uncertainty. They are driven and passionate about being outstanding scientists and helping those coming up behind them.

This means individuals in the following statuses at the time of application are eligible:

Undergraduate in the final (senior) year of a bachelor’s degree program
Bachelor’s degree-holder with NO enrollment in a graduate degree program (non-degree graduate coursework allowed)
Individual enrolled in a joint bachelor’s-master’s degree program with at least three undergraduate years completed
First-year graduate student in their first graduate degree program with less than one academic year completed in the degree program (according to institution’s academic calendar)
Individuals enrolled in joint bachelor’s-master’s degree programs are considered graduate students. For GRFP, joint bachelor’s-master’s degrees are defined as degrees concurrently pursued and awarded.
Not be a current NSF employee.

Applications that do not meet eligibility requirements will be returned without review as being ineligible for a fellowship.

These later ended up in the Paleontology Research Labs at South Dakota School of Mines and Technology where they are in prominent display. Note is from the department’s 2010 newsletter.

I was asked yesterday to post a walkthrough of Life Over Time, the shortest-lived and generally weirdest iteration of the Field Museum’s fossil halls. If you visited between 1994 and 2004, this is the version you saw. I’ve got some time, so let’s do this.

A carnival-like exhibit entrance with a dinosaur skull, coelacanth model, and pantodont skeleton in cases under freak show-style banners labeling them as "Mesozoic terror" and "the fish that wouldn't die'

Elevated temperatures do all sorts of weird things to organisms, usually bad things. Foraminifera, for example, sometimes shrink in size. The interesting bit is, when they do that, their shell becomes tougher. 🧪🌊

Outputs of FEA models showing the von Mises stress on shells under loads of 20 kPa with current and future shell parameters. The models represent current size based on average diameter and volume of shells from the control stations, and future size is reduced by 56% as indicated by shells from the warm stations.
