I rarely advertise any projects. I mostly have students come through from undergraduate projects. So I know them well beforehand. I Australia we put forward students for scholarships and they are ranked by our graduate school following a set of criteria.

Does the student working for someone you already know and trust help?

Does it help if the student met you at a conference?

Any other tips for prospective students to shine in a graduate school application?

Your advice on any or all of this is greatly appreciated.

How highly do you weight undergraduate GPA?

How highly do you weight recommendation letters? What kind of stuff do you look for in a recommendation letter?
whysharksmatter.bsky.social
How do you choose who makes the short list? What skills or experience makes someone move to the top of the pile?

How much does having a publication already matter?

How much does having lab/field experience already matter?

If you have a spot for a graduate student in your lab, do you advertise it publicly, internally, or not at all?

How many people people typically apply for an advertised spot? What percentage of them are reasonably qualified?

Colleagues in ocean science academia: 🧪🦑🌎

I am working on the section of my marine biology career advice book about applying to graduate school. I have lots to say here from both my own experience and years of teaching this stuff, but I’d welcome your input on any or all of this if you’re willing.

Western Alaska was hit hard by the recent storms. Houses floated away in Kipnuk, houses flipped over, people lost everything from the flooding that came with the storms. Please donate if you can. This group has a long history of supporting AK communities.

NEW: @soleilho.com went to Portland to investigate Antifa “hellfire.”🔥 All they found was an exceptional brunch 🍳 🥐 The real terror? Having to choose between Pine State Biscuits and Mémoire Cà Phê for breakfast. (They chose both.)
Portland Is a ‘War Zone’? OK, Sure. So How’s the Food?

Offer also good for anyone else reading this.

When you visit Friday Harbor Labs, @fishguy.bsky.social always has cool fish to discuss 🐟 Last week we pondered the horned searobin (Bellator militaris), & what its spines could be for. CT scan available on MorphoSource for you to explore

We tagged it, so what? Tags reveal where sharks travel and when, giving us a glimpse into their secret lives. These insights guide better protections (and make cool squiggly lines on maps). We are so close to funding the next tag. Let’s goooo! Invite your friends!

This is a powerful account from a PhD student whose fellowship was terminated by NIH because it was part of a "diversity" program without any other considerations or understanding of what the program or the students were actually doing.

NIH Student Grant Cancellation Will Weaken Scientific Innovation
The termination of federal F31 diversity fellowships puts many graduate students in a bind — and U.S. science at risk.

Was worried that this was going to be *yet another* of the "people should all go back to Twitter" nonsense pieces, but @ianbetteridge.com's law of headlines rarely fails. The answer here is a clear "no" with good reasons:
Well – no. Bluesky may or may not be, as one centre-right friend who felt unwelcome put it, “self-righteous island”. But the idea that that is the reason why we went is nonsense. That I’ve largely stopped posting on a site that’s done more to shape my career and social circle than the rest of the internet combined is less about avoiding rival opinions (I love arguing with people who are wrong) than with the fact the site simply became unusable. It stopped generating the things (good jokes, interesting debate, clicks) I wanted; it became extremely good at generating the things (racists, pornbots, racist pornbots) I did not. Those who stayed behind have lost something, too: the ability to not have their worldview shaped by some of the maddest people on the internet. One of the Tories’ big conference announcements was the promise of an Ice-style border force that would deport [citation needed] 150,000 people a year. That mass deportations of most existing migrants is not actually popular in the UK – that such a policy places yet more distance between the Tories and the mainstream centre which deserted them last year – seems not to have occurred.

It’s hard not to connect this to the fact that much of the political class remains on a platform now dominated by the political extremes. They might do well to remember: Twitter is not the real world.

Statistics on how scientists feel about their presence on Bluesky versus Twitter. My personal experience (before closing my Twitter account in August 2023) was that engagement for my tweets had dropped to close to zero. No longer worth the effort...
