Controversial comet theory struck by two new retractions In a now-retracted paper, the authors report they found shocked quartz formed by an airburst from clouds of comet fragments that hit earth more than 12,000 years ago. Source PLOS One has retracted …

Two more YDIH papers bite the dust.

I really don't understand the framing of this. Even if the local sea level deviates from the geoid, this doesn't make the risks of sea level rise worse, since sea level rise is not a function of sea level.

In situ cosmogenic 10Be and 26Al reveal the complex exposure and erosion history of the landscape once covered by the Quebec-Labrador Ice Dome Abstract. The rate at which ice sheets erode rock and produce sediment is poorly known. Here, we use paired cosmogenic nuclides in both deglacial and modern sediment to understand better the efficacy ...

Guess what. Glaciers aren't as good at eroding the landscape as we might have thought. New paper with collaborators from Quebec, France, and across the US. Internationalism lives on at least in science!

I think it is mistake to think that social media is a good place to advertise creative work like journalism. It is a place where people share their feelings and reactions. I usually only post about science, but despite 3000 followers, rarely do things I post get more than a few retweets.

At this point, I will really only accept review requests for short form Nature/Science/Geology/GRL papers, because I can't justify reviewing a big 10,000 word manuscript, especially if I have to review it twice. I am not secure enough in my employment situation for that.

It is especially frustrating when after the second round of review, the paper is rejected. What a way to waste my time.

It doesn't help that almost every time, the paper is sent back for re-review after revisions. The editor really needs to read the response themselves and make a judgement of whether or not the authors sufficiently answered the review. For long papers, it is a lot of work to review twice!

Maybe OrcID could provide a service like that. Maybe not even a full on email service, but an address that would forward emails to whatever email you have linked to your account.

I would still use Gmail for any correspondence that might continue after the contract is over. If they didn't like it, I would make them guarantee access to email after the contract is over (in writing). My old ANU account is still accessible, it is possible to do that.

Is that a new thing? When I was at AWI, there were no restrictions like that (or at least they didn't tell me anything to that extent). Maybe the rules were different because I was a post-doc.

Those cracks in the bottom right are opening up fast!

One thing I have learned over the years is to only use institutional email addresses for institution business. Anything outside of that, including correspondence with colleagues and submitting papers, should be done with Gmail or similar service.

A nice reminder that 1) some impact records are, in fact, real and 2) they can get published in legit journals.

I’ve watched Next Goal Wins and so I am probably qualified for this job at the University of the South Pacific. plusportal.perrettlaver.com/VacancyDetai...

Apparently, a dyke injection event is ongoing near Irabu Knoll, at the southern Okinawa Trough back-arc basin. (Hypocenters: JMA; Bathymetry: GEBCO, JAMSTEC, Japan Coast Guard)

I just started up writing a second manuscript. Can I finish both manuscripts this month? It would be a good conclusion to all the work I have done in my spare time during the past two years.

I saw some posts about Homo Erectus, and it got me thinking. How did Homo Erectus get out of Africa? The ice sheets in the Early Pleistocene were not as big as the Middle and Late Pleistocene, so sea level would not have dropped as much.

The Kamchatka earthquake last year could apparently be felt here in Kyushu, but I was on a bus when it arrived. Similar distance!

Sounds like a situation where adding more buses would make sense? How does raising the fees help?
