Crater tree rings
This feature could easily be mistaken for a tree stump with characteristic concentric rings. It’s actually an impressive birds-eye view into an ice-rich impact crater on Mars. Tree rings provide snapshots of Earth’s past climate and, although formed in a very different way, the patterns inside this crater reveal details of the Red Planet’s history, too.

The image was taken by the CaSSIS camera onboard the ESA/Roscosmos ExoMars Trace Gas Orbiter (TGO) on 13 June 2021 in the vast northern plains of Acidalia Planitia, centred at 51.9°N/326.7°E.

Why economists would publish in the health field is weird, I guess they don't have an outlet like Paul Krugman does in the NYT.

I read the opening disclaimers and abstract. The disclaimers are strong enough if you open the document, which is iffy as a citation. Reading it, you can't miss that they are economists.

The rest of the this paper goes over my head in some ways, in others it appears to me that they are acting like cold blooded capitalists who only care about the bottom line, and don't care if 1) we were/are still learning about this fucking bug and 2) all experts were guessing about the impacts. Hell, the agreement on this disease being airborne vs tactile isn't really that old, we got to that early last year and the damage to the economy was already vast.

OK, today we can agree that some of the means used to try to save lives didn't work, like sanitizing your groceries, but PEOPLE tried them, they weren't mandated, weren't the NPI's. The impact of COVID on air travel wasn't due to bans, it was due to you and me saying, no way, I'm not getting on an airplane until I know for sure it won't kill me. We all saw the pictures of empty planes in route in 2020. The knock on impact to car rental and tourism is well known, our area is a tourist destination and it really did fuck things up here for a while. I'd like to see them quantify the fear that we all went through in 2020 which propelled us to stay home, it had little to do with any lockdown, per se, we still shopped for groceries and hardware as needed, but no one knew enough to say we should do THIS and not THAT.

Fucking eggheads ...

Your opinion is topical to me today as in our local newspaper there was a lengthy Sunday article on how the latest 30 day ban on groups of 50 or more in our county "blindsided" business, hurt catering and event planners, and on and on. It could have been a press release from the Chamber of Commerce, which was quoted more than once. One mention of the possible impact of infection in our "rural county with limited medical facilities" from our local Health Officer and then on and on about the costs. It seems this is going to be rehashed again and again, armchair quarterbacks blaming the public health officials and the costs of being safe.

We keep a bucket in our kitchen sink to catch gray water. It gets soapy often. A random tests of the pH returned values of 7.5 to 8.5 which made me think this is too sweet for blueberries and the azalea. A quick check shows that many crops like lettuce, arugula, spinach, chard, kale are all OK with alkaline, so the water is being used there. Life in a severe drought sucks, but at least we learn as we conserve.

Today's release of the PROMED bulletin had these notes about the FLU:
==============================================
[1] USA (Wisconsin)
Date: Thu 17 Mar 2022
Source: Wisconsin Department of Health Services [edited]
https://www.dhs.wisconsin.gov/news/releases/031722.htm


The Wisconsin Department of Health Services (DHS) has confirmed the
deaths of 3 children under the age of 18 due to complications from
influenza. These are the first reported pediatric influenza-associated
deaths in Wisconsin for the 2021-2022 season.

"DHS is deeply saddened to report these flu deaths in Wisconsin this
influenza season," said state health officer Paula Tran. "It is
important to remember that along with COVID-19, other communicable
diseases such as flu are circulating in our communities. Each of these
alone can pose serious health risks for children, and co-infection can
occur. It is not too late for Wisconsinites to get vaccinated to
protect themselves and others."

With the number of flu cases and hospital admissions rising throughout
the state, DHS encourages Wisconsinites to get vaccinated. The flu
vaccine is the best way to prevent severe illness associated with the
influenza virus. Everyone over 6 months of age is recommended to get
the flu vaccine. Specifically, it is highly recommended for people who
are at greater risk of becoming seriously ill, such as those who are
pregnant, over age 65, and those with chronic health conditions. DHS
recommends Wisconsinites talk with a healthcare provider if they have
questions about the flu or getting vaccinated. It is never too late to
get a flu shot.

As COVID-19 continues to circulate across Wisconsin, staying up to
date on COVID-19 vaccines also remains critical. You can get your flu
and COVID-19 vaccines at the same time. Vaccine finder
(https://www.vaccines.gov/) is a free tool that can help
Wisconsinites find a vaccine provider near them.

In addition to getting vaccinated, taking everyday actions to stop the
spread of germs can help prevent the flu and other respiratory
illnesses:
- wash your hands often with soap and water;
- avoid touching your nose, eyes, and mouth;
- stay home and away from others if you feel sick;
- avoid being around others who are sick or have flu symptoms;
- cover your nose and mouth when you cough or sneeze and encourage
children to do the same.

Up-to-date information on the current flu season can be found in the
DHS Weekly Respiratory Report
(https://www.dhs.wisconsin.gov/library/p ... 021-22.htm).

[ProMED thanks Elizabeth Goodsitt for sharing the relevant data on
pediatric deaths associated with influenza over the last 5 seasons up
to 2022. The data indicate that the figures are similar during the
2021-22 season.

The global influenza update no. 415 dated 21 Mar 2022, based on data
up to 6 Mar 2022
(https://www.who.int/teams/global-influe ... nza-update)
includes the following statement: "In North America, influenza
activity increased in recent weeks but remained lower than
pre-COVID-19 pandemic levels at this time of the year and was
predominantly due to influenza A viruses, with A(H3N2) predominant
among the subtyped viruses." - Mod.SH

This supports the relevant seasonal update shared for Wisconsin state
as well. - Mod.UBA

http://outbreaknewstoday.com/denmark-re ... ses-78374/


Since large parts of Danish society were shut down on 12 Mar 2020 due
to COVID-19, the incidence of influenza has been at a very low level
until the beginning of 2022. Now the number of people infected with
influenza A is doubling from week to week.

In Denmark, the incidence of influenza tends to increase at the end of
December. But this season, the flu has started very late, after being
almost completely absent for the last 2 years during COVID-19.
Currently, however, there is a steep increase in the number of flu
cases in most of the country. In recent weeks, the number of infected
has thus doubled from week to week and in week 10 reached 1179
infected.

A total of 2533 cases of influenza have been detected this season. The
vast majority of cases -- a total of 2459 -- are caused by the type of
influenza virus called A/H3N2. It is a well-known flu type, which is
also circulating in other countries. H3N2 is included in the seasonal
vaccine, but it is known to change and this may reduce the effect of
the vaccine. This season, changes have been seen in the H3N2 viruses
in circulation, which may mean that the vaccine has a reduced effect.

Influenza has been detected in all age groups. At present, however, a
predominance of children and the younger part of the population aged
15-44 as well as people over 85 years of age are affected by
influenza.

It is now more than 5 months since seasonal flu vaccines became
available. The late onset of influenza prevalence is therefore a
challenge, as the effect of vaccines decreases over time.

In the age group 2-6 years, the effect of the influenza vaccine, which
is targeted at children, is calculated at 71% against influenza A. In
the age group 7-44 years, the effect is calculated at 43%, while in
the age group 45 years and over, no effect against the circulating
influenza A type. "Despite the fact that the vaccine effectiveness
against influenza infection is not measurable in the age group 45 and
above, the vaccine will probably still have some effect against
serious illness if you become infected with influenza," says section
leader Ramon Trebbien from Stans Serum Institut (SSI).

It is not so surprising that the best effect of the flu vaccine is
seen among the children, as children generally have a good ability to
form antibodies after being vaccinated. In addition, vaccinated
children aged 2-6 years have received 2 doses of the live attenuated
childhood vaccine, which was introduced in the Danish vaccination
program for the influenza season 2021/22.

Fire season is already ongoing, and Arizona's an eager participant in the season with fires by Flagstaff and Prescott. I don't suppose that any firefighting equipment companies are moving beyond drones for reconnaissance and adapting ground and air drones for actual fire suppression yet? Even if it was a "follow the leader" type of Loyal Wingman deal where the drones mostly imitated a lead, human-piloted vehicle, that could still add a lot of fire suppression potential without needing to train so many more people for the equipment.

I suppose not allowing the CO2 and methane atmospheric levels to be so high would also help with wildfire prevention.

Just an anecdote about how much of a game changer drones can be in terms of fire management. <snip>

Unfortunately I haven't followed up with the agency about whether they've adopted this approach since then - haven't thought about it much until now. Next time I chat to them I'll ask. But I do know that in the last two or three years drone's s have exploded use have increased in vegetation management applications, both fire and herbicide applications as well as remote sensing.

Exploding drones are not good for fire management. :scared:

I hope they have a sufficiently beefed up their ferret corps to deal with the newly invented infrared chainsaw drones. Science is so hard these days.


You mean the "Fouine" aka pine marten? Nasty. Had that rider on my car insurance in Switzerland, but never saw one nor any damage to my Twingo.
Wait, are you not aware of the long history of ferrets saving particle accelerators? Well I've got a treat for you. It all started when a ferret (named Felicia) was commissioned to be sent through the actual accelerator at Fermilab. I believe she was used for both cleaning and checking the particle path for blockages.

Lovely, the impact of international (and inter-specie) collaboration!

transhumance
trăns-hyoo͞′məns
noun
Transfer of livestock from one grazing ground to another, as from lowlands to highlands, with the changing of seasons.
the moving of cattle or other grazing animals to new pastures, often quite distant, according to the change in season
The American Heritage® Dictionary of the English Language, 5th Edition.

I was browsing the stacks at the county library historical branch and came across a "Historical Atlas of California". In it was a heading for Transhumance Grazing in the Sierra Nevada where, to this day, livestock is herded up into the mountain pastures over the course of the summer season. I had never heard this term before and spent some time reading up on it on the internet. I think it is a subject that would make a great video documentary.

We have two fancy wood cut-out/silhouette Swiss trinkets celebrating the cows going up or down to the pastures, flower wreaths in their horns. Some places still do value this, but the Swiss are like that. I read that there are others who do the same trying to preserve the traditions, French Basque, Basque and others in the hills, IIRC, some places in the Balkans as well. These are the easy reads in a search on transhumance, much better documented than the way things work in California, say.

One essay I read mentioned that in the early days, 1850's in California, the European shepherds who migrated here also set the high pastures on fire when they left them, a trick they learned from the Native Americans. In some respects, these ideas are coming back full circle as prescriptive burns are being discussed in the state today.

The ownership of marginal lands in eastern California, the water rights, mining, grazing are all tied together in this topic as well. The state is still charging a grazing fee per head on the sheep that are moved up slope on the eastern Sierras.

My family is engaged in a large farming effort which attracts a lot of young people every year. They're working towards an organic remake of the farm, livestock, orchards, truck farm, and harvesting (animal and crop) and the young 'interns' are working their tails off. The only problem is, they can't get a foot hold once they strike out on their own, the land is the hardest thing to find. Here the large dairy farms are burning out, no more water, market crashes, other crazy forces are going to break up "old ag" and hopefully the kids will get to apply their knowledge before Bill Gates and the hedge fund assholes turn it all into something else.

Let's just hope that the toe-hold that transhumance has remains and doesn't die off.

The reason being that heterogenity and the unequal distribution of key resources across the landscape.
It was Karl Polanyi who outlined the decline of the agricultural systems of the commons in Europe by the monarchies giving title to lands their barony could then fence off and exploit, along with the labor which was communal prior and became feudal. I forget what the act in England was called that facilitated that, but it was early (~1450?). He was the first to introduce me to that piece of history.

After reviewing the abstract of the above citation, I was curious if there are any range lands left in a state that can prove or disprove the benefits of efforts to restore them to their preindustrial levels. The Wikipedia has a List of protected grasslands of North America but protected is not the same as wild, for example. The prairies here in the USA were targeted for their rich soils which we promptly mismanaged and degraded. The efforts to rewild the countryside in England gets enough coverage in the Guardian to catch notice, but again, will it ever go back to the state it was in?

What's your opinion of the State's oversight of those grazing resources?
I'm woefully unread in this area but that chance encounter at the library did peak my interest. The combination of "rights" outlined in our posts above, it is a complicated issue. It makes me want to watch "Manon of the Spring" again :) Coincidentally, I started to reread DUNE, I have the edition with the appendices, one of which covered the work of Pardot Kynes and his terraforming work on Arrakis. It is all about water here in California too. Fiction isn't a complete waste of time if it makes you think about topics like this (or I tell myself.)

While I'm not as old as the industrial revolution, I was born at 312 ppm (1951) and we're now at 414 ppm. Hmmm, I thought this revelation would have more impact, but it doesn't. I now have a life goal to burn less, but that was acquired post Y2K - it will never make up for the 1961 Cadillac I drove for years in my youth.
Planting the right trees can help.

It is common knowledge among galley cooks that porridge like substances are both sentient and out to get you.

Lesson #1, never trust grits to stay in the pot, it will always erupt and get you on the back of the hand even if it too is in a hot water bath in a steam table. In the years I spent in the galley, I don't recall oatmeal having any special properties other than it will burn the fuck out of you when you are serving a heaping helping to a hungry ship mate, which will cause the bowl to fly across the galley and land in the sink next to the 3rd cook. But, I was never shocked by oatmeal.

Also, the slickest substance known to man is commercial grade FRY-KING by Cargill. Next is rendered bacon fat.

On Saturday last, the neighbor lady found a dead crow in her driveway. It was the first of two, the second being today in our backyard. We think they are the pair of juveniles being raised since spring in the 'hood. Due to "business hours", we buried the first carcass on Saturday, the folks at our mosquito control service only want to pickup on weekdays, preferably during business hours, 8 AM to 4:30 PM.

So, this time, I double bagged the carcass according to instructions found here and will wait until they can come and get the critter tomorrow. They are testing for avian flu and West Nile viruses.

It will be quiet in the trees until the next brood comes along, hopefully, Ma and Pa are OK, we'll keep our eye out for them. They are regulars at our "feeding stone" where we leave scraps for the neighbor cat, what he doesn't get, they do. We are guessing that it is the young ones, they grow large quickly and it is hard to tell by size. The call of the young ones, if missing, will tell us who died.

Added: The unmistakable call of the juvenile was heard, so we wasn't the deceased. Now, we have to try to determine who it was. Tough when everyone looks alike but sounds different.

I'm reading up on landfilling plastic as a carbon sink. One group suggests that we store our plastic waste until such time as we can really recycle it or find another use for it. In the meantime, it is carbon stored out of the system and if done right, it wouldn't degrade as it would in a landfill. Where to store so much material is a stumbling block.

The chit chat about using cryogenic sorting for EV batteries made me wonder if something similar could be used to sort plastic by density, which I understand is one problem in its reuse, mixing the types of polymers in the recycling systems.

Also, any complaints about microplastics is conflicted by tire shredding in our daily driving.

Man spent two days aloft after balloon he was using to harvest pine nuts became untethered.

I don't know if the tech used by these nut pickers would assist NASA at the pad, but you never know. If they can keep a gas bag inflated with hydrogen for days, they might know something we don't. I know, unlikely it was liquid.

In the New York Times today, an article on Perseverance and some new rock samples. They say:
NASA and the European Space Agency are collaborating on a follow-up robotic mission known as Mars sample return to pick up Perseverance’s rock samples. That mission is scheduled to launch in 2028 with the Martian rocks landing on Earth in 2033.

So, we'll need a mnemonic for this mission: Mars Sample Return Pick-up or MSRP, no?

And now, for something completely different; on SWISSINFO, an essay on the results of a test run during the last 18 months - Buried underwear proves good soil in private gardens.

This is a test we could do in our yard, except I'm not sure how to factor in the impact of the drought, the soil is bone dry a few inches down after our dry year.

The study also demonstrated how important humus content is for the soil water balance. “The more humus a soil contained, the more water it was able to store,” Bender added.

My wife's MIGROS panties lasted the longest of any panties she ever had, it was a sad day when she had to move on to dainties bought in the USA. COSTCO undies are not the same, for some reason, we feel that the MIGROS undies were real cotton, the COSTCO, while labeled 100% cotton, didn't feel the same (she said ;) ). So, my 100% cotton Land's End boxers are, I'm sure, not 100% cotton, but this technique could prove they are mislabeled.

"Physics : a short history, from quintessence to quarks" by J.L. Heilbron was a good read. He started back in ancient history and traced the development of what we call physics today, bring in aspects from Asian and Middle-eastern history, seeding European developments through to now. He makes some assumptions about your knowledge level but brings you along as the subject gets more complex.

I was given a copy of "We Have No Idea - A Guide to Unknown Universe" by J. Cham and D. Whiteson last summer and am getting around to reading it. It is a pun filled exploration of dark matter and energy, gravity, sub-atomic and particle physics. It is laced with cute cartoons and, as I said, filled with puns. 99% of the footnotes so far have been jokes or puns, so I'm now ignoring them.

Heilbron's book was very well written and pulled you in to what could be a dry subject. He kept it interesting all the way through. Cham and Whiteson seem to be relying on cute as a means to deliver some very complicated subject matter and they do a good job, up to a point. I'm finding I'm getting annoyed with the cute and craving the dryer prose, avoiding the cartoons and pun filled footnotes. There is subject matter filling in gaps in my knowledge, which is excellent, but it is a bit of a slog.

I may have read a "for dummies" book years and years ago, but I feel like the Cham and Whiteson mode of writing is evolved out this vein. I'm going to try to finish it, we'll see if I can.
What do you think, is cute a good means to get science delivered or a hindrance?

Hmmm, again, a not-so-science post, other than applied science via learning aviation. But it's Scott Manley!

Scott Manley learning to fly

The newish cockpit layout is interesting enough. I wonder if it helps with information overload? I also wonder what operations training adjustments will be needed for electric planes vs the regular avgas ones. You won't have a throttle in the traditional sense anymore.

Aircraft and flight science itself is quite something, but actually learning to fly would be a great way to put it all into perspective.
A pilot pal of mine loaned me "Stick and Rudder: An Explanation of the Art of Flying" by Wolfgang Langewiesche years ago. Everytime I strap into my Flight Simulator I remember some of the fundamentals discussed in that book. "Push into a stall, don't pull back" and "the plane knows how to fly."

IMO it's probably essential if you want to reach the sizable audience of laymen that would never pick up a book of 'dry' science.

Does engaging with 'cute' science help? I would guess it increases public support of science in general, but I suppose we should set up a study to determine that.
Yes, but Heilbron's book was engaging which would pull in anyone who tried it (and can read). I doubt that the For Idiots series of books would be the phenom it is if it didn't fill a need.
So, we need a control group ...
