Digger

August 21, 2025

Following my disappointment fishing while at the coast last week I decided to walk through the beach community and see if I could spot some birds that were not yet on my list.  I took the road through the community first to try and spot land birds.  I was able to see two species I already recorded, an American Crow (Corvus brachyrhynchos) and a flock of house sparrows (Passer domesticus).  It was not until I returned along the beach that I picked out several forms of gulls (California gull, Larus californicus; western gull, Larus occidentalis; short-billed gull, Larus brachyrhynchus) and a flock of white-winged scoter (Melanitta deglandi) ducks.  The beaches along the Puget Sound tend to be small well-worn rock rather than the sand I associat with other coasts.  This is harder to walk on, and it took me a while to get back to the house.  When I arrived, my daughter-in-law showed me a picture of the unusual wasp they had encountered on their beach walk (other direction).  It was a large golden digger sand wasp.

When I went online, I found the golden digger sand wasp (Sphex ichneumoneus), or great golden digger wasp or great golden sand digger, is a wasp in the family Sphecidae.  The wasp’s name comes from the Greek word for “tracker,” and is most well-known for its parasitic nesting behavior.  It is identified by the golden pubescence on its head and thorax (chest), its reddish orange legs, and partly reddish orange body.  Golden hairs cover the head and thorax (hence “golden”).  The digger has a long, slender waist (petiole).  Their hind region (metasoma) is black with the first couple of segments a brilliant orange-red that matches their legs.  Size varies from 1/2 to over 1 inch (1-1/4 to 2.5+ cm) long.  This wasp is native to the Western Hemisphere, from Canada to South America, and provisions its young with various types of paralyzed Orthoptera (grasshoppers and crickets). 

From May through August, great golden digger wasp females build their nests in sandy soils.  These consist of a descending shaft and side chambers for the young at right angles.  This makes it difficult to pull prey into a brood chamber without getting stuck and is one possible reason why the wasp always checks to ensure the path is clear before pulling its prey down by its antennae.  Female wasps commonly build their burrows nearby those of other females of their species and may even share a nest.  However, they will fight other wasps if they encounter them inside their burrow during prey retrieval.  By inspecting the unattended nest, the wasp avoids risking an encounter with another wasp while carrying its prey.  The digger will track and hunt their prey (i.e., tracker) and sting it with a paralyzing venom that keeps it alive, then flies (or drags) the prey to the nest.  At the nest the digger wasp lays down their paralyzed prey and enters her tunnel and checks to ensure that all is well.  Then she brings the prey down into a side chamber, lays an egg on the prey, and seals the chamber.  When the egg hatches it feeds on the prey through the winter, and the new wasp emerges from its side chamber in the spring and begins the cycle again. 

THOUGHTS: The golden digger sand wasp is like the cicada killer (Sphecius speciosus) I saw last week in Arkansas.  Both are large, solitary, build nests in the ground, are harmless to humans, and do not defend their nest or behave aggressively.  While they have stingers, they rarely sting humans unless they are stepped on.  The digger is a pollinator that preys on insects that are harmful and are helpful to have around your garden (or beach house!).  These are possibly the only wasps known to be attacked by birds.  House sparrows and American robins (Turdus migratorius) will attack to force the digger to drop its prey for the bird to eat.  I guess both the young and the birds are looking for an easy meal.  Act for all.  Change is coming and it starts with you.

Sea Lion

August 17, 2025

One of the joys of visiting family is being able to spend time on the ocean coast.  My sister lives in Maine and we always take time to visit the ocean for at least one day during the trip.  My son’s family lives near Seattle and has a beach house near the Tulalip Tribe’s reservation.  This weekend we were able to go to Seattle and spend two days on the coast.  The first day my young grandson took me fishing on the rock beach behind their house.  He made two casts and immediately caught a 6-inch (15 cm) sculpin (Hemilepidotus spinosus).  After two more casts, he offered the pole to me.  I took several casts and did not get a bite.  My grandson seemed to get bored and went back to play at the house.  I kept casting for another 10 minutes and did not get a bite the entire time.  I gave up and went to sit on the deck and watch the beautiful sunset.  After several minutes my daughter-in-law noticed a sea lion had ventured into our part of the bay and was bobbing up and down in the channel.

When I went online, I found the California sea lion (Zalophus californianus) is a coastal eared seal native to western North America.  It is one of six species of sea lions.  It has a natural habitat range from southeast Alaska to central Mexico, including the Gulf of California.  California sea lions are sexually dimorphic with the males being larger than females. Males have a thicker neck and a protruding ridge of bone lengthwise along the top of the skull (sagittal crest).  The animals will mainly haul out on sandy or rocky beaches, but they also frequent manmade environments such as marinas and wharves.  Sea lions feed on several species of fish and squid and are preyed on by orcas and great white sharks.  The sea lions have a polygynous (multiple partners) breeding pattern.  Males establish territories from May to August and try to attract females to mate.  Females are free to move between territories and are not coerced by males.  Mothers nurse their pups in between foraging trips.  California sea lions use many vocalizations, but most notably barks and mother-pup contact calls.  Outside breeding season, California sea lions spend much of their time at sea but come to shore to molt.  The International Union for Conservation of Nature (IUCN) lists the species as Least Concern due to its abundance.  Oregon and Washington states engage in annual kill quota to protect the fish.

When I woke up the following morning, I decided I would try my luck with fishing again.  When I fished yesterday it had been high tide (the best time to catch fish on this beach).  Now it was low tide.  Undeterred, I took the poll and strode to the water’s edge and began to cast once more.  I found out why it is best to fish at high tide almost immediately.  On nearly every cast I fouled my hook in the lush beds of eel grass (Zostera marina) that covered the bottom of the channel.  Besides providing excellent forage for the California sea lions, the sea grass meadows provide food and shelter for juvenile fish, Dungeness crabs (Metacarcinus magister), the Pink (Chlamys rubida) and Spiny Scallops (Chlamys hastata). and other marine life.  They serve as a food source for herbivores during the growing season and for things that feed on the decomposing grass (detritivores).  The seagrasses absorb carbon dioxide, filter polluted runoff, absorb excess nutrients (nitrogen and phosphorus), stabilize sediments, and improve water flow. 

THOUGHTS: One of the questions I was frequently asked after moving from California’s Bay Area to southcentral Kansas was if it was any different where I used to live.  I rented a house at a marina on the bay with a boat slip out my back door.  My stock answer was, “well, I have not been greeted by the sound of a sea lion when I wake up in the morning.”  While not getting any bites the second day, I spotted a sea lion pup and mother foraging nearby.  It was good to know I was in a healthy ecosystem.  We need to do what we can to keep them that way.  Act for all.  Change is coming and it starts with you.

Outburst

August 16, 2025

A USA Today article reported how water from a melting glacier has caused a river near Alaska’s capital city of Juneau to swell to historic levels.  As of August 13th, emergency barriers protecting Juneau appear are holding.  The risk from summer glacial flooding is on the rise as climate change increases temperatures, causing more ice to melt.  Lakes form behind the unsteady dams made of ice and when these dams fail, the water rushes out, often resulting in catastrophic downstream flooding.  The ice dam lake near Juneau ice is called Suicide Basin, which is part of the Mendenhall Glacier.  If it collapses from summer heat it will release the water in a short period of time.  Aaron Jacobs, a hydrologist at the National Weather Service office in Juneau, said as these events continue to unfold, scientists need to continue to improve their understanding of these glacial systems, especially as the climate continues to change and warm throughout Alaska.  Glacial lake outburst flooding is produced by the quick, unexpected release of water from a glacial lake.

When I went online, I found a glacial lake outburst flood (GLOF) is a type of outburst flood caused by the failure of a dam containing a glacial lake. A similar event where the ice melts and overflows the glacier is called a jökulhlaup.  The dam can consist of glacier ice or previous glacial deposits (moraine).  Failure can happen due to erosion, buildup of water pressure, an avalanche of rock or heavy snow, an earthquake, or by a sudden cracking action in frozen soil or rock saturated with water or ice (cryoseism), volcanic eruptions under the ice, or massive displacement of water in a glacial lake when a large portion of an adjacent glacier collapses into it.  Increasing glacial melting because of climate change along with melting of the permafrost means regions with glaciers are likely to see increased flooding risks from GLOFs.  This is especially true in the Himalayas where geologies are more active.  A 2023 study found 15 million people at risk from this hazard, mostly in China, India, Nepal, Pakistan, and Peru.

Glacial lake volumes vary but may hold millions (35,314,666+ cubic feet) to hundreds of millions of cubic meters (3,531,466,600+ cubic feet) of water.  Catastrophic failure of the ice or glacial sediment containing the water can be released over periods of minutes to days.  Peak flows as high as 529,720 cubic feet (15,000 cubic meters) per second have been recorded in such events.  This suggests the v-shaped canyon of a normally small mountain stream could suddenly develop an extremely turbulent and fast-moving torrent of water some 160 feet (50 m) deep.  Glacial Lake Outburst Floods are often compounded by a massive riverbed erosion in the steep moraine valleys resulting in flood peaks increasing as they flow downstream until the sediment deposits.  On a downstream floodplain, it suggests a somewhat slower inundation spreading as much as 10 kilometers (6.2 mi) wide.  Both scenarios are significant threats to life, property and infrastructure.

THOUGHTS: The glacial outburst in Alaska is not a new phenomenon and has occurred annually in Suicide Basin since 2011.  What is new in the last few years is the amount of water being released all at once during these events.  According to the National Centers for Environmental Information Alaska has warmed twice as fast over the last several decades Information compared to the rest of the US.  Its average annual temperature has risen 3.1F (-16.0C) in the past century.  Since 1990, humans have been the primary cause of melting glaciers worldwide due to rising temperatures from the burning of greenhouse gases and land-use changes.  Such an outburst can be prevented.  Act for all.  Change is coming and it starts with you.

Cramps

August 15, 2025

We decided it was time to visit my son and his wife (and especially the grandkids!) and arraigned for the flight to Seattle, Washington.  We previously took advantage of a direct flight when we lived in Wichita, Kansas.  The flight was set up to quickly fly air manufacturers and reps between their factories in both cities.  Even after moving to Arkansas, we took this flight since both mom and my brother lived in Wichita.  We would drive to see them and then fly direct to Seattle.  This time we decided to fly from the regional airport next to us rather than drive 5 hours prior to the 3-1/2 hour flight.  The difficulty with our local airport is they only fly to big hubs and then you still need the same amount of time to get to your location.  That meant we took a short flight to Dallas/Fortworth, had a quick layover, and still had the 3-1/2 hour flight to Seattle.  This was complicated further as our puddle jumper got in 20 minutes late and left us only 35 minutes to catch our next flight (no stress here).  Luckily, that flight had difficulty boarding passengers and we easily made the next leg.  We arrived just after my son flew into the same airport and had an exciting evening watching grandkid activities (football and cheer).  We went to bed early after the long day, but both Melissa and I both woke up in the middle of the night with leg cramps.

When I went online, I found that long flights can result in leg cramps.  Everyday leg cramps are often caused by muscle strain, exercise, or dehydration, but long flights can introduce extra complications that increase the risk of cramps.  The main cause is long periods of sitting still in cramped conditions. Even when sitting for long periods at work or at home, we have the freedom to move and stretch.  Sitting on a long flight has limited leg room that reduces the natural muscle contractions in your legs crucial for pumping blood back to your heart.  This causes sluggish circulation, allows blood to pool, and makes muscles far more vulnerable to cramping.  Long flights can also create dehydration from the dry cabin air (humidity is often 10 to 20% compared to 40 to 50% on land) and pressure changes during take-off and landing.  This makes your muscles more prone to painful cramps.  However, there are ways to help prevent painful cramps.

I found a site that listed five ways to prevent the painful cramps we both experienced.  The first is to start hydrating 1-2 days pre-flight, wear loose fitting clothing, and consider wearing compression socks to promote better blood flow.  Once on the flight, make it a priority to get up and move around the cabin at least once every hour and resist the urge to cross your legs (impedes blood flow).  There are simple exercises you can perform to maintain circulation.  These include ankle circles, foot pumps, knee lifts, calf raises, and leg extensions.  Next, find ways to stay hydrated while in the air by drinking at least 8.5 ounces (250 ml) of fluid every hour you are in the air.  Finally, avoid alcoholic beverages (a diuretic) as these encourage your body to lose more fluids and increase your risk of cramps.  Drinks with high sugar content (fruit juices and soda) can also pull water from your system as your body tries to process it.  While not glamorous, plain water is best for preventing leg cramps.

THOUGHTS: When Melissa and I woke up with cramps we both immediately thought of grabbing an electrolyte drink which provides minerals in your body fluids that carry an electric charge.  My son is a fitness aficionado, so I figured he would have something.  I looked through the drinks stored in the garage and checked the refrigerator, but to no avail.  Getting moving seemed to help.  When he got up, I asked, and he had several powdered remedies rather than a liquid version.  Between the electrolytes and moving the cramps went away.  Now that I know the secret to avoiding cramps, I am ready for our return flights.  Like most things, planning in advance and proper execution can make life easier.  Act for all.  Change is coming and it starts with you.

Mite

August 13, 2025

It was only fitting after blogging on the cicada-killer wasp (Sphecius speciosus) that I found another species that attacks the broods as they emerge.  Buried in the back section of my local newspaper was an article about a mite that attacks the periodical egg nests of cicadas.  The species commonly feeds on the larvae of midges (various Suborders of Diptera) or flies and form an abnormal outgrowth (gall) as a reaction to both the insects and the mites feeding on them on the edges of pin oak (Quercus palustris) leaves.  Once their development is complete, they drop from the tree and can land on, and subsequently bite, humans and animals.  According to Penn State Extension, the bite can cause an itchy rash, redness of the skin, and a small, raised pimple-like bump.  They usually bite humans while searching for other food sources. 

When I went online, I found oak leaf itch mite (Pyemotes herfsi), also known as the oak leaf gall mite, was first identified in Europe and subsequently found in India, Asia, and the US.  The mites live on the surface of the host’s skin (ectoparasitic) feeding on blood or skin cells.  The mite is barely visible, measuring about 0.008 to 0.03 inches (0.2 to 0.8 mm).  Newly emerged and mated females inject a neurotoxin-containing saliva into their hosts, which paralyzes the host and enables the pregnant (gravid) female to feed on the host’s body fluid (hemolymph).  The posterior portion (opisthosoma) of the female enlarges as its young develops inside, and after several days up to 250 adult mites emerge, of which 92% were females.  Males emerge before the females, position themselves around the mother’s genital opening, and mate with emerging females.  The mated females then disperse to find new hosts.  The mites are often dispersed by wind, and when they land on vertebrate hosts, they attempt to feed, resulting in the bites.  Their great reproductive potential, small size, and high capacity for dispersal by wind make them difficult to control or avoid.

Humans are most likely to get bites while doing yard work or outdoor activities under trees that may be infected.  The University of Maryland Extension recommends you avoid scratching the bite as this may lead to a secondary infection.  Instead, use an itch relief product.  If the itchiness or redness persists or signs of infection appear you should consult a doctor.  The best way to avoid bites is to limit time underneath potentially infected trees and to immediately remove and wash clothing once coming inside.  While that may be good advice, it does not seem like I would remember to do either.  The mite is most active for a four-to-six-week period surrounding cicada brood hatches.  Studies have shown in some cases the mite can survive mild winters in protected areas.  A suggested preventive measure is the application of DEET before outdoor activity.  However, anecdotal reports suggest DEET might not provide complete protection.   

THOUGHTS: The oak leaf itch mite was first recognized in the US with an outbreak in Kansas which affected around 19,000 people in 2004.  The mite was also linked to a 2007 outbreak of rashes in Chicago where they were feeding on the eggs of the 17-year cicada.  The double brood hatch in 2025 again brought the mite back in force.  I have noticed a proliferation of YouTube videos depicting humans assisting other animals in removing parasites or other things that have overwhelmed a larger animal (perhaps because I watched one and it is now on my feed radar?).   Even at the top of the food chain it does not keep humans from becoming food themselves.  Being wary of your surroundings can help keep you safe, but living in fear restricts your appreciation of the beauty of nature.  Act for all.  Change is coming and it starts with you.

Arborist

August 12, 2025

I came across another example of how one decision leads to the necessity of making others this week.  We have been checking out buying a motorhome for the last eight years.  We began when we still lived in Kansas, but after the move to Arkansas the concept fell off our radar.  This last year my sister and brother-in-law purchased a small teardrop trailer with their son and then a larger trailer for their use.  They camped most of their married life, so this was not a surprise.  She told us that while it was cheaper to stay in a hotel than buy and maintain a trailer, they enjoyed the outdoor freedom.  One reason I (and now Melissa) retired was to travel.  Now that we have the kids, this has become problematic (for me).  It is more difficult to find a hotel that allows pets (not impossible) and even more so now that we have 175 pounds (75 kg) of dogs.  Boarding is a possibility but adds another US$1,000 to the vacation.  That moved us to buy a Class C motor home.  These vehicles are smaller than the Class A motorhomes and have slide-outs for maximum square footage.  The purchase meant we also needed to decide where to keep the vehicle.  The fenced side yard was an obvious choice, but that meant we needed to enlarge the gate and cut down a tree for access.  While I could have taken days to cut the tree and haul it to the dump, we decided to call an arborist. 

When I went online, I found arboriculture is the cultivation, management, and study of individual trees, and other perennial woody plants, and a person who practices or studies arboriculture is called an arborist.  The science of arboriculture studies how these plants grow and respond to their environment.  The practice of arboriculture includes techniques for selection, planting, training, fertilization, pest and pathogen control, pruning, shaping, and removal.  A tree surgeon is more typically someone who is trained in the physical maintenance and manipulation of trees and more a part of the arboriculture process rather than an arborist.  Risk management, legal issues, and aesthetic considerations have come to play prominent roles in the practice of arboriculture.  Businesses often hire arboriculturists to complete “tree hazard surveys” and generally manage the trees on-site to fulfill occupational safety and health obligations.  Arboricultural matters are also considered to be within the practice of urban forestry, yet the clear and separate divisions are not distinct or discreet.

Both the arborist and the fence man showed up at the same time today.  While they were working in the same area of the yard, they did not seem to interfere with each other.  The tree came down in a matter of hours (not my days) and the limbs were either ground or stacked in 15-inch (38cm) lengths to be used as firewood when we go camping.  The fence took a little longer.  It needed two posts removed and another set.  This shortened the total area but allows for a 12.5-foot (3.8 m) entrance.  That is enough to safely drive my 10 foot (3 m) wide motor home through the gate and park it in an enclosed area.  As I said, one decision often leads to several others. 

THOUGHTS: One of the reasons people call an arborist is the perceived risk of death by falling trees.  This is influenced by media and often hyped, and the risk has been reported to be close to 1:10,000,000, or almost as low as death by lightning.  Trees in urban green spaces and their careful conservation are sometimes in conflict with aggressive urban development, despite how urban trees contribute to livability of suburbs and cities objectively (reduction of urban heat island effect, etc.) and subjectively.  Tree planting programs implemented by a growing number of organizations and cities are mitigating the losses and often increasing the number of trees in suburbia.  This includes planting 2 trees for every 1 tree removed or paying landowners to keep trees instead of removing them.  Each tree absorbs about 55 pounds (25 kg) of C02 annually.  My two fruit trees help replace the one Bradford pear (Pyrus calleryana).  Act for all.  Change is coming and it starts with you.

Cicada-killer

August 11, 2025

I have been seeing the scattered exoskeletons of the cicada (superfamily, Cicadoidea) brood hatch that is occurring in Arkansas this summer.  Brood XIX emerges every 13 years, and its last emergence was in 2011.  It is a large brood that encompasses 15 states.  Although they are not in Arkansas, Brood XIII is also emerging in other parts of the country.  Although the cicadas are large and a brood hatch can become messy when great numbers emerge at the same time, they are not agricultural pests or a threat to humans.  Trees may be overwhelmed by the sheer number of females laying their eggs in their shoots and small branches.  Yesterday while watering my garden, I noticed what looked like a large wasp trapped between the screen and window on the porch.  When I find wasps on our porch, I shoo them away or if they persist, I will spray them.  I have been stung too many times to allow these pests to establish close to our house.  The insect looked like a yellow jacket but was over twice the normal size.  What I found out was this was an eastern cicada-killer.

When I went online, I found the eastern cicada-killer wasp (Sphecius speciosus) is a large, solitary digger wasp species in the family Bembicidae.  They are also erroneously called sand hornets, although they are not true hornets, which belong to the family Vespidae.  Their name comes as they hunt cicadas and provision their nests with them.  The species is found in the Eastern and Midwest US and south into Mexico and Central America.  Adult eastern cicada wasps are 0.6 to 2.0 inches (1.5 to 5.0 cm) long.  They have hairy, reddish, and black areas on their middles (thoraces), and black to reddish brown rear (abdominal) segments that are marked with light yellow stripes.  The wings are brownish.  The females are slightly larger than the males, and both are among the largest wasps in the Eastern US.  European hornets (Vespa crabro) are often mistaken for eastern cicada killers, although they are smaller at 1.4 inches (3.5 cm) long.  The males are smaller than the females because they are not given as much larval food.  The females benefit from being larger as they must carry the cicadas they have killed to a burrow for nesting.  Cicada killers exert a measure of natural control on cicada populations which may directly benefit the deciduous trees the cicadas feed on.  

Despite their fearsome appearance, female cicada-killers are not aggressive and rarely sting unless they are mistreated.  Their sting is not much more than a “pinprick”.  Males aggressively defend their perching areas on nesting sites against rival males, but they have no stinger.  Although they appear to attack anything that moves near their territories, male cicada killers are just investigating anything that might be a female cicada killer ready to mate.  Their close inspection may appear to be an attack, but male and female cicada killers do not land on people with the intent to sting.  If handled roughly, females will sting, and males will jab with a sharp spine on the tip of their abdomen.  They are generally not aggressive towards humans and usually fly away rather than attacking.  I initially tried to swat the wasp but its size and being behind the screen protected it.  I finally gave up and decided if it could get out of the screen on its own it would go away.  Since it was not there this morning, I assume it had done so. 

THOUGHTS: The size of the cicada-killer and its resemblance to a yellow jacket made me fearful when I first encountered it.  It seemed docile rather than the aggression I have seen from other wasps.  Still, I wanted it to go.  After I found out what it was, I was glad I left it alone.  We do not have a cicadae problem, but this was nature’s way of providing control.  One benefit of my garden is taking time to observe the interaction between the flora and fauna (plants and animals) that thrive there.  Identifying the different species and their place in my sub-ecosystem has been enlightening.  We are all part of the same planet.  Act for all.  Change is coming and it starts with you.

Hadal

August 04, 2025

Inside the front section of Friday’s newspaper was a Reuters article about a new discovery in the northwest Pacific.  Thriving communities of marine creatures turn chemicals into energy rather than eating organic matter.  These chemosynthesis-based animal communities were dominated by tube worms (Riftia pachyptila) and clams (genus, Spisula) and were found during a series of dives aboard a crewed submersible to the bottom of the Kuril-Kamchatka and Aleutian trenches.  The creatures are beyond the reach of sunlight and are nourished by fluids rich in hydrogen sulfide and methane seeping from the seafloor.  These ecosystems were discovered at depths greater than Mount Everest (29,032 feet/8849 meters).  The deepest ecosystem was 31,276 feet (9,533 m) below the ocean surface in the Kuril-Kamchatka Trench, or 25% deeper than such animals had previously been documented.  The research was published on Wednesday in the journal Nature.  Marine geochemist Mengran Du of the Institute of Deep-sea Science and Engineering, said, “What makes our discovery groundbreaking is not just its greater depth – it’s the astonishing abundance and diversity of chemosynthetic life we observed.”  The discovered ecosystems exist in the hadal zone.

When I went online, I found the hadal zone, or hadopelagic zone, is the deepest region of the ocean found only within the oceanic trenches.  The hadal zone ranges from around 3.7 to 6.8 miles (6 to 11 km) or 20,000 to 36,000 feet below sea level, in the long, narrow, topographic V-shaped depressions.  The cumulative area occupied by the 46 individual hadal habitats worldwide is less than 0.25% of the world’s seafloor, but the trenches account for over 40% of the ocean’s depth range.  Most hadal habitat is found in the Pacific Ocean, the deepest of the conventional oceanic divisions.  The deepest ocean trenches are considered the least explored and most extreme marine ecosystems and are characterized by a complete lack of sunlight, low temperatures, scarce nutrients, and extremely high pressure exerted on an immersed body (hydrostatic pressures).  The major sources of nutrients and carbon are fallout from upper layers, drifts of fine sediment, and landslides.  Most organisms are scavengers and animals that subsist on decomposing plants and animal parts (detrivores).  As of 2020, over 400 species are known from hadal ecosystems, many of which possess physiological adaptations to the extreme environmental conditions.  There are high levels of a species being found in a single defined area (endemism).

While some marine animals have been documented at even greater depths, (36,000feet/11,000 m) below the surface in the Pacific’s Mariana Trench, those were not chemical eaters.  In the new research, scientists used their submersible (the Fendouzhe) to journey down to the hadal zone.  The hadal zone is where one of the continent-sized plates that make up Earth’s crust slides under a neighboring plate in a process called subduction.  Marine geologist and study co-author Xiaotong Peng, said this environment harbored “the deepest and the most extensive chemosynthetic communities known to exist on our planet.”  The newly observed ecosystems were dominated by two types of chemical-eating animals.  Tube worms that were red, gray or white in color and around 8 to 12 inches (20-30 cm) long and clams that were white in color and up to 9 inches (23 cm) long.  Some of these appear to be previously unknown species.

THOUGHTS: Even in the harsh environment of the hadal zone life has found a way of surviving and thriving.  Some non-chemical-eating animals were also found living in these ecosystems.  The study illustrates how life can flourish in the most extreme conditions on Earth (and beyond?).  This makes it possible (even probable) that exploration will find life on Earth is not alone.  The question will be how we handle the discovery.  Act for all.  Change is coming and it starts with you.

Pressure

August 03, 2025

I decided I had enough tomatoes (Solanum lycopersicum) to make another batch of pasta sauce.  We used the last 2024 jar during January and have been using “store-bought” sauce.  I like the store brand, but it never seems as good as my home canned sauce.  The recipe calls for 25 pounds (11.3 kg) of tomatoes and makes around 10 quarts (9.5 liters) of sauce.  I never have that many tomatoes at one time, but I had prepped and frozen a gallon (3.8 liters) from a previous harvest and the cool(er) spell last week produced another burst of fruit.  This would give me 4 or 5 jars of sauce, so I adjusted the recipe accordingly.  I have been able to make my sauce using a water bath (boiling water) due to the higher acidity of the tomatoes.  Last week I had also prepared the carrots from my garden and the slices were sitting in the refrigerator.  I had been reluctant to can them because of their low acidity.  To can the carrots, I would need to do something I had never done before, use a pressure cooker.

When I went online, I found a pressure cooker is a sealed vessel for cooking food (pressure cooking) with the use of high-pressure steam and water or a water-based liquid.  The high-pressure limits the water from boiling and creates higher temperatures not possible at lower pressures.  This allows the food to be cooked faster than at normal pressure.  The prototype of the modern pressure cooker was the steam digester invented in the 17th century by the physicist Denis Papin.  The cooker worked by expelling air from the vessel and trapping steam produced from the boiling liquid.  The steam is used to raise the internal pressure up to one atmosphere above normal (ambient) and gives higher cooking temperatures between 212 F to 250F (100C to 121C).  Together with high thermal heat transfer from steam it permits cooking in between a half and a quarter of the time of conventional boiling while saving a considerable amount of energy.  Almost any food that can be cooked in steam or water-based liquids can be cooked in a pressure cooker. 

Modern pressure cookers have many safety features to prevent the pressure cooker from reaching a pressure that could cause an explosion.  After cooking, the steam pressure is lowered back to ambient atmospheric pressure so the vessel can be opened.  All modern devices also have a safety lock to prevent opening while the cooker is still under pressure.  According to the NY Times Magazine, 37% of US households owned at least one pressure cooker in 1950, but by 2011 that dropped to 20%.  This decline was attributed to a fear of explosion (rare with modern pressure cookers) and from competition by other fast cooking devices such as the microwave oven.  Today’s third-generation pressure cookers have many more safety features and digital temperature control, do not vent steam during cooking, and are quieter and more efficient.  These conveniences have helped make pressure cooking more popular.  I bought Melissa a third-generation electric pressure cooker (an odd gift?) before we were married.  I later found out she never used it. 

THOUGHTS: As I was making the carrots Melissa told me of her experience with an early pressure cooker.  She loved to watch her granny canning in the kitchen when she was a small girl.  Then one afternoon when she was three, the old-style first-generation pressure cooker exploded, sending hot water and glass everywhere.  Both her granny and mom wore glasses, but she did not, and glass got in her eyes.  A quick trip to the doctor removed all the glass, but neither she nor her mom ever watched granny using the pressure cooker again.  Even with the modern versions, her dad was the only one in the house who used one.  It took me a week to build up the nerve to use the pressure cooker.  I had never used one and had “heard the stories”.  I went online to learn how to operate it and found it easy to use.  I now have a new cooking method to add to my resume.  New things are generally only daunting if never tried.  Act for all.  Change is coming and it starts with you.

Honeycomb

July 30, 2025

Today’s MSN browser had an article about a discovery that has resolved a 70-year debate.  A team of chemists and archaeologists used cutting-edge analysis techniques to test the pasty residue found in the bottom of bronze jars found in the sixth-century BCE city of Paestum in southern Italy.  The researchers published their findings today (July 30) in the Journal of the American Chemical Society.  The 8 bronze jars were discovered in an underground shrine in 1954.  Honey and honeybees were important in ancient Greek and Roman medicine, rituals, cosmetics, and food, so it was assumed the substance was remains of ancient honeycomb offered as a symbol of immortality.  Despite at least four attempts over seven decades to confirm the presence of honey, no evidence of sugars was ever found.  Lead author Luciana da Costa Carvalho, a chemist at the University of Oxford, England, and colleagues decided to take advantage of recent advances in chemical analysis techniques and reopen the question of the substance’s origin.  Using mass spectrometry to identify the different molecules and compounds, researchers were able to identify intact hexose sugars in the ancient jar residue for the first time, confirming the jars originally contained honeycomb.

When I went online, I found a honeycomb is a mass of 6-sided (hexagonal) prismatic cells built from beeswax by honeybees (genus, apis) to contain their brood (eggs, larvae, and pupae) and stores of honey and pollen.  Honeybees consume about 8.4 pounds (3.8 kg) of honey to secrete 1 pound (450 g) of wax so beekeepers may return the wax to the hive after harvesting the honey, leaving the comb intact to improve honey output.  The honey is extracted by uncapping and spinning in a centrifugal honey extractor.  If the honeycomb is too worn out, the bees can reuse wax by making sheets of comb foundation with a hexagonal pattern.  These foundation sheets allow the bees to build the comb with less effort, and the hexagonal pattern of worker-sized cell bases discourages the bees from building the larger drone cells.  New honeycomb is sometimes sold and used intact, especially if the honey is spread on bread rather than used in cooking or as a sweetener.  The brood comb becomes dark over time (travel stain) due to empty cocoons and shed larval skins embedded in the cells, along with being walked over constantly by other bees.  Honeycomb in the hive boxes (supers) that is not used for brood stays light-colored.

The research presents the first direct molecular evidence supporting the presence of honey, which was likely offered as honeycomb.  Analysis of the goop can help archaeologists better understand ancient rituals and shrines.  The jars were found in an underground shrine (heroon) that included a large, wooden table with wool-wrapped iron rods placed on top.  The offering may have been made to Is of Helice, the mythical founder of the ancient Greek city of Sybaris, located in what today is the arch of Italy’s boot.  When Sybaris was destroyed in the sixth century BCE, its inhabitants fled and founded a city called Poseidonia.  When the Romans took the city in the third century BCE, they renamed the city Paestum.  The new study shows that “there is merit in reanalyzing museum collections because analytical techniques continue to develop,” according to Carvalho.

THOUGHTS: I have always preferred eating honeycomb over straight honey.  Most of what I ate growing up was based on texture rather than taste, and I enjoyed the honey squishing out of the cells when I comped down on the waxy comb.  Raw honey and beeswax are the two main components of honeycomb.  Raw honey is rich in enzymes and antioxidants, while beeswax contains long-chain fatty acids and alcohols, all of which may benefit your health.  As I have aged my eating habits have changed (I will not say refined).  Texture is important, but taste also decides my diet.  Is must have felt the same way about his offerings.  Act for all.  Change is coming and it starts with you.
