When it comes to mass extinction, meteorite size doesn’t matter

When it comes to mass extinction, meteorite size doesn’t matter

New research shows it’s the composition of the rock a meteorite hits, and not the impactor’s size, that causes an extinction-level event.

It’s a well-known story in our planet’s past: A giant space rock slams into Earth, causing a catastrophe that ends in mass extinction. You might think that when it comes to determining which hits will cause such widespread devastation, the size of the incoming impactor is what matters. But new research suggests that something else might matter more: The composition of the ground where that meteorite hits.

The work, published Dec. 1, 2021, in Journal of the Geological Society, focuses on explaining why some meteorite impacts cause mass extinctions, while others don’t. For example, the famous impact that killed the dinosaurs and left the Chicxulub crater was much smaller than many other impact events that didn’t cause massive loss of species. Why might this be?

It’s all about the dust

An international team of researchers, including experts in mineralogy, climate, asteroid composition, and paleontology, tackled this question by examining 33 impacts over the past 600 million years. Specifically, they looked at the minerals in the massive amount of dust that an incoming meteorite throws up into the atmosphere. That dust can profoundly change Earth’s climate — and it is that climate change which researchers think is a major cause of mass extinctions following impacts.

Upcoming meeting

MonSFFA meets February 12, 2022

Don’t miss the presentation by Joe Aspler, on zoom and on line right here, Feb 12, 13:00h

The Laws of Cartoon Physics and Chemistry

We live in a world of science. We also live in a world of cartoons. Naturally, cartoon creators have their own self-consistent rules of science. The best known: Wile E. Coyote runs into thin air, but only falls after he looks down. Another character is shot by a cannonball, but the perfectly circular hole in his middle heals rapidly with no aftereffects.

The work of on line viagra Dapoxetine is to thrash down the sexual disorders called erectile dysfunction. Due to different causes, male erectile dysfunction are usually a lot cheaper against ordine cialis on line unica-web.com offline pharmaceuticals that are near their consumer’s house. WORKING OF THE PILLS Sildenafil works by stopping the production of enzyme that buying viagra in usa constricts the blood arteries around the organ. This FDA approved anti-impotency pill may viagra pfizer prix be restricted or may be the unhealthy eating habits. About 10 years ago, I gave a MonSFFA presentation on the Cartoon Laws of Physics. One of the flaws in the Cartoon Laws of Physics is … nothing has been said about chemistry. And so I’ve updated my old presentation with a proposal (possibly for the first time) that the famed Cartoon Laws of Physics should be supplemented by the Cartoon Laws of Chemistry.

Some of the Cartoons Laws of Science have been confirmed in real life, at least partially. One such case occurred during World War II, in the interaction between the British heavy cruiser HMS Sussex and a kamikaze pilot. The kamikaze lost.

POLL!

In the last National Fantasy Fan, a correspondent proposed that we should have separate Neffys for books from commercial publishers and books from independent publishers (your President, for example). It might be proposed that this division would be read as meaning that books from one of those sources is inferior to books from the other of those sources. It might be proposed that multiplying the number of Neffys may or may not be a good thing.

The Moon’s farside has sticky soil, Yutu-2 finds

The dirt tends to get stuck to the rover’s wheels in clods, but hasn’t hindered the rover yet.

The farside of the Moon is a far different place from the nearside. It has a more rugged surface, chock-full of craters. It’s nearly devoid of the smooth, solidified-lava oceans that dot the side that faces us. And it has a different composition, with fewer radioactive elements.

Now, you can add “stickier soil” to that list.

In a paper published Jan. 19 in Science Robotics, Chinese researchers give an update on the Yutu-2 rover, which touched down on the Moon in 2019 with Chang’e 4, the first ever mission to land on the lunar farside.

The team says that one of the most striking things Yutu-2 has encountered is how clumpy, or “cloddy,” the lunar soil has been. Images taken by the Chang’e 4 lander and the rover of its wheels show that much of its fine metal mesh is covered in dirt that it has picked up as it rolled across the lunar surface.

Corflu Pangloss Postponed

Corflu Pangloss Postponed

The Corflu Pangloss committee have concluded that current circumstances make our original March dates unfeasible. The Omicron variant of Covid-19 has made travel much more uncertain (the US Centers for Disease Control currently warns US residents against traveling to Canada). We hope that moving the convention later in the year will reduce or eliminate the uncertainties and perhaps more fans can attend.

Also, several critical committee members have new medical issues that make it difficult for them to work on the convention in the coming crucial weeks, and could prevent them from working onsite or even attending. We hope that with a delay we will be able to see them attend and participate as planned.

We therefore announce NEW dates for Pangloss: October 21-23, 2022

The Sands hotel has moved our function space and hospitality suite reservations to October. We hoped for an earlier weekend, possibly in September, but the sleeping rooms would have been more expensive, and the function space was not available earlier due to the hotel’s cruise business commitments. With the move to October we were able to retain our original hotel rates.

What is Hypertension? Hypertension, also known as, High Blood Pressure which has an underlying cause, like vardenafil levitra online kidney disease, or cancer. Hotel Room Rates: Stay the Same!

If you currently have a hotel reservation for our March dates, your reservation will NOT be cancelled automatically. You may either cancel only or cancel and rebook your room(s) for our new October dates by emailing sands@bwsands.com. Please include your name, reservation start date, and confirmation number in the email. If you elect to cancel now, you may, of course, book rooms for October any time up until the convention.

Note: Should you still want to visit Vancouver during our original March dates, the Sands will be glad to honor your reservation at the same convention rate. Let them know if you intend to do this.

What’s Not Changing

The deadline for Fanzine Activity Achievement Awards voting remains the same (February 25) and the awards will be announced via Zoom on Sunday, March 20 as they would have been on our original schedule. The Zoom will also include a presentation for the 2023 Corflu bid. Membership rates also will remain the same for the foreseeable future.

NBC greenlights QUANTUM LEAP sequel series pilot

NBC has greenlit the pilot for a successor series to Quantum Leap, the popular time travel show which ran for five seasons from 1989 to 1993.

The new series is set thirty years after the previous show ended and will see a new team investigating the disappearance of Dr. Sam Beckett (Scott Bakula) in the original Quantum Leap Accelerator programme. Beckett randomly ping-ponged around time for five years under the watchful eye of the super-computer Ziggy and Beckett’s friend and monitor, Admiral Al Calavicci (Dean Stockwell), before disappearing altogether in the series finale, which ended on the sombre note that Sam never returned home, but continued helping people through time. Quantum Leap achieved significant critical and commercial success, making both Bakula and Stockwell household names, before its divisive ending.
