Gleanings of the Week Ending January 27, 2024

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Can autoimmune diseases be cured? - After decades of frustration and failed attempts, scientists might finally be on the cusp of developing therapies to restore immune ‘tolerance’ in conditions such as diabetes, lupus and multiple sclerosis.

Good and bad news for people with low back pain - The good news is that most episodes of back pain recover, and this is the case even if you have already had back pain for a couple of months. The bad news is that once you have had back pain for more than a few months, the chance of recovery is much lower. This reminds us that although nearly everyone experiences back pain, some people do better than others, but we don't completely understand why.

Why diphtheria is making a comeback - While this present surge of diphtheria cases is indeed unprecedented for West Africa, it is really a symptom of larger issues in global health, including insufficient infectious disease surveillance, poor vaccination rates and scarcity of public health resources.

The Prairie Ecologists Photos of the Week – January 22 2024 – Photographs from out in the cold.

The chemistry of meat alternatives – It’s complicated…..in the end are meat alternative ultra-processed food?

The strange reasons medieval people slept in cupboards – I can see how they might have been warmer….but also rather claustrophobic. And wouldn’t they be hard to keep clean?

In the time of the copper kings - Some 3,500 years ago, prosperous merchants on Cyprus controlled the world’s most valuable commodity. Beginning in the third millennium B.C., and especially during the second millennium B.C., copper was king and could make those who possessed it extremely wealthy and powerful. There was enough copper and tin on board the Uluburun ship (wrecked off the coast of Turkey) to produce 11 tons of bronze, which experts estimate could have been turned into 33,000 swords. Researchers have analyzed the Uluburun wreck’s copper and found that it all came from Cyprus. There is evidence of the surprisingly diverse nature of the community thriving there and that those Cypriots who controlled the production and distribution of copper, such as the shipment found off Uluburun, could become exceptionally rich.

Cicadas Are Coming: Rare ‘Dual Emergence’ Could Bring One Trillion of the Bugs This Year – We don’t live in the overlap area…but where we live in Missouri will see Brood XIX this summer….a great opportunity for cicada photography!

Incredible Winners of the Close-Up Photographer of the Year Contest – So many beautiful images. My favorite is ‘Spirit of Yucatan’ (drifting stems of lily pads in a Mexican freshwater cenote…the sky above).

Deepwater Horizon oil spill study could lead to overhaul of cleanup processes worldwide – Chemical oil dispersants combined with sunlight…made oil more toxic. Observations from after Deepwater Horizon, and being confirmed experimentally, to improve responses to oil spills.

My Favorite Photographs of 2021

It was a challenge to pick one picture from each month of 2021 to feature in this post….but a worthwhile exercise. I did not use consistent criteria for my choices, so these images are special for a variety of reasons.

January for witnessing interesting bird behavior – A bluebird on our deck railing looking up at our bird feeder full of other members of the flock…waiting a turn!

February for learning to make high key images – A high key image of a lily….the flower purchased at the grocery store. I had just watched a video about high key photography and was thrilled to have some easy successes.

March for beauty old and new – The crocus were out at Brookside Gardens but I found the remnants of last seasons flowers more interesting.

April for a bird trusting that I wasn’t a threat– A bird looking rather assertive. I had paused its search for food in the leaves to make sure I wasn’t a threat; evidently I wasn’t because it went back to its search a few seconds later.

May for memorializing a bird – A juvenile little blue heron in the cattail leaves at Josey Ranch in Carrollton TX. It had a broken wing so I think of this image as a monument to its short life.

June for something that only happens every 17 years – The periodic cicadas seemed to be thick everywhere – even our yard. This one was under our red maple.

July for interconnection in nature– Back in Texas…am insect on a cosmos flower on a cool morning.

August for the fragile beauty of a new butterfly – A monarch butterfly seconds after it emerged from its chrysalis is our front flower bed.

September for capturing a small thing, seeing it better than I could with my eyes – Some birds nest fungus in the mulch at Howard County Conservancy. I was thrilled that I had my gear (phone, clip on macro, clicker) even though I hadn’t planned to do any macro photography!

October for being in a river – More macro photography – this time the wing of an insect on a rock just above the water line….photographed on a volunteer gig before the students arrive.

November for the colors of the flower – Another view of a cosmos flower. I like it when the light is such that a black background is possible.

December the new orb sculpture at Brookside – A surprise (for me) at Brookside – I hadn’t seen this sculpture before…and I also enjoyed the holiday lights (missed them last year).

Cicada Aftermath

The Brood X adult cicadas are gone; the outdoors is quiet in comparison to the way it was a month ago. The trees are showing the impact of the large numbers of cicadas that emerged this year…but not all the trees were impacted the same. Our oak seems to have the most small-stem breakage from the cicada eggs deposited under the bark…the larvae hatching and dropping to the ground. The stems split and the leaves past the split die. The condition is called ‘flagging.’

Some of the leaves are already falling off the tree; they’ll be mulched into the yard the next time we mow.

There are other insects that enjoy our oak. I noticed that some of the leaves on the ground have holes in them. Without the cicadas, the leaves probably would have stayed green and on the tree for the rest of the summer.

The sycamore is impacted to a lesser degree.

It appears from the yard that the small branches are falling off more quickly than the oak’s.

I took some zoomed pictures of the sycamore branches. The color and shapes appeal to me.

Soon the aftermath of the Brood X will all be underground….the larvae beginning their 17 year journey.

There was a story in the news of some research into the blue jay and grackle die off recently….looking at whether the fungus that seemed more prevalent in the cicadas this year might have impacted the juvenile birds that ate them. The die off occurred in the same areas where Brood X emerged.
