Frank Lloyd Wright’s Iconic Hollyhock House Faces Closure Amid City Cuts – Budgets tightening across the board. It seems that cultural things previously funded by governments are among the first to go.

The surprising power of breathing through your nose – The nose can be the first line of defense for your immune system. Mouth breathing has been shown to increase acidity and dryness in the mouth, linking it to cavities, demineralization of the teeth and gum disease. You can think of the nose like a wind chime for the mind; when air moves through your nose, it seems to have a significant influence on your cognitive processes. Nasal breathing has positive effects on the limbic system – the parts of the brain that regulate emotion and behavior – in ways that mouth breathing doesn't.

Spring (Baby) Fever – A baby animals quiz….with cute pictures.

Dust in the system -- How Saharan storms threaten Europe's solar power future - New research reveals how Saharan dust impacts solar energy generation in Europe. Dust from North Africa reduces photovoltaic (PV) power output by scattering sunlight, absorbing irradiance, and promoting cloud formation. Based on field data from 46 dust events between 2019 and 2023, the study highlights the difficulty of predicting PV performance during these events.

In Galápagos, Iconic Giant Tortoises Get a Helping Hand - Fifteen species of giant tortoises — the largest in the world — once roamed the Galapagos Islands but today only 11 survive. Dome-shelled tortoises reach sexual maturity at 20 to 25 and lay 16 to 20 eggs at a time. When the park was established in 1959, some of the tortoise species were heading towards extinction while others were deemed vulnerable or threatened. But a captive breeding program launched in 1965 has shown great success and has released more than 10,000 giant tortoises back into the wild.

Walmart Announces Nationwide EV Charging Network - According to a press release from the company, “With a store or club located within 10 miles of approximately 90% of Americans, we are uniquely positioned to deliver a convenient charging option that will help make EV ownership possible whether people live in rural, suburban or urban areas.”

Shingles vaccine lowers the risk of heart disease for up to eight years - There are several reasons why the shingles vaccine may help reduce heart disease. A shingles infection can cause blood vessel damage, inflammation and clot formation that can lead to heart disease. By preventing shingles, vaccination may lower these risks. Our study found stronger benefits in younger people, probably due to a better immune response, and in men, possibly due to differences in vaccine effectiveness. The study was done in South Korea.

Hikers Make Stunning Discovery of $340,000 Gold Hoard in Czech Mountains - Most of the coins are French with the overall hoard broadly dated from 1808 to 1915. There is, however, a notable exception: the Austro-Hungarian coins. Small markings on the coins, known as countermarkings, indicate that they were reissued in 1921 in an area of Yugoslavia most likely encompassing modern-day Serbia and Bosnia and Herzegovina. The hoard remains under investigation and archaeologists hope that with the aid of archival records they will be able to work out the full story behind the treasure.

All of the biggest U.S. cities are sinking - The fastest-sinking city is Houston, with more than 40% of its area subsiding more than 5 millimeters (about 1/5 inch) per year, and 12% sinking at twice that rate. Some localized spots are going down as much as 5 centimeters (2 inches) per year. Two other Texas cities, Fort Worth and Dallas, are not far behind. Some localized fast-sinking zones in other places include areas around New York's LaGuardia Airport, and parts of Las Vegas, Washington, D.C. and San Francisco. Massive ongoing groundwater extraction is the most common cause of these land movements. In Texas, the problem is exacerbated by pumping of oil and gas. Droughts will also likely worsen subsidence in the future. Some buildings in the Miami area are sinking in part due to disruptions in the subsurface caused by construction of newer buildings nearby.

How Herbicide Drift from Farms Is Harming Trees in Midwest - There’s growing evidence that agricultural herbicides — which are also used on golf courses, lawns, and rights of way — are inflicting widespread damage on trees and other vegetation across the Midwest and upper South and perhaps doing broader ecological harm as well. The problem is causing increasing concern and even alarm among landowners, state forestry officials, and scientists. In 48 percent of the cases, researchers found damage more than 1,000 feet from the nearest farm field; six samples showed herbicide damage at more than a mile.

Whorls of White off Greenland – A satellite image (from the Terra satellite), captured on February 24, 2025, shows the southern part of Greenland, from its snow-topped ice sheet and glaciers to the sea ice swirling along its coasts. When this image was acquired, the sea ice extent along Greenland’s East Coast was about average. However, Arctic-wide, sea ice in late February was exceptionally low for the time of year due to a warm winter.

The baby boom in seven charts - The US baby boom is typically defined as the time period between 1946 and 1964. But – it appears that the increase in birth rate began earlier…in the late 1930s. And it happened in many countries at the same time. This common trend across many countries suggests that the baby boom was driven by shared societal shifts rather than isolated national circumstances. The baby boom was also surprising because it happened alongside rising levels of women’s education and workforce participation — changes that now often coincide with falling birth rates.

Cheap Chinese Panels Sparking a Solar Boom in the Global South - A surge in solar installations in parts of the developing world. The glut of cheap solar means poorer countries can speed their shift away from fossil fuels while shoring up their supply of energy.

Following Frogs into the Flames – The tree frogs are using the trees all the way up to 40 feet, up to the crown of the tree, as a safe place during fires, and also for several weeks after the fire, when the ground is still somewhat inhospitable.

Brewing tea removes lead from water – Brewing black tea in cellulose tea bags works best for removing lead…longer steeping removes more.

Where California’s Land Is Sinking and Rising – Analysis of vertical land motion between 2015 and 2023. Areas of sinking land in coastal California cities and in parts of the Central Valley are caused by factors like soil compaction, erosion, and groundwater withdrawal.

Oldest Section of China’s Great Wall Uncovered - The recent excavations occurred around what is known as the Qi Wall, which was already considered to be the oldest in existence. New dating, however, suggests that the wall’s construction originates to the late Western Zhou Dynasty (ca. 1050–771 BC) and the Spring and Autumn Period (770–ca. 475 BC), making it 300 years older than previously thought.

What happens when a diet targets ultra-processed foods? - The findings suggest that people can reduce their ultra-processed food intake, if given the proper tools, and that they will be enthusiastic about interventions designed for this purpose. The results also suggest that reducing UPF intake will lead to meaningful health improvements -- such as weight loss and better mood -- in as short as eight weeks.

Glass fertilizer beads could be a sustained nutrient delivery system - Excessive and inefficient use of agricultural fertilizers can present an environmental threat, contaminating waterways and generating greenhouse gases such as nitrous oxide. Now, researchers have addressed those challenges with glass fertilizer beads. The beads control nutrient release….releasing fertilizer over a longer time period.

Historic Frank Lloyd Wright Home Gifted to Chicago University – The last remaining example of Wright’s prairie-style designs. When the Bach residence was completed in 1915, it boasted walnut furnishings throughout and a clear view of Lake Michigan from its rear porch.

Rare ‘Doomsday’ Oarfish Surfaces in California, Just the 20th Discovered in the State Since 1901 - Usually lives as far as 3,280 feet below the surface. Scientists conducted a necropsy, but they couldn’t discern a reason for the elusive fish’s death. Scientists aren’t totally sure why oarfish and other deep sea-dwelling creatures sometimes surface, but they suspect the animals may be disoriented, sick or injured.

Owl-Inspired “Bionic” Fan for EVs Reduces Fan Noise 50% While Improving Efficiency 10% - Making EVs even quieter!

Do you have knee pain from osteoarthritis? You might not need surgery. – Article written by researchers in Australia about the updated treatment guidelines for knee osteoarthritis that stress exercise, increasing physical activity, weight management, and pain medication (in moderation and not opioids). The links at the end of the article include an online exercise program specifically for knee osteoarthritis.

Frank Lloyd Wright’s Only Skyscraper Set to Close Amid Controversy – Price Tower in Bartlesville, Oklahoma. Built in 1956. Designated a National Historic Landmark in 2007.

Rebuilding the Genome of Woolly Mammoths - Typically, ancient DNA fragments yield short snippets of DNA and provide an incomplete picture of the genomic puzzle. However, the woolly mammoth skin sample showed promise. The team assembled the first 3D reconstruction of the woolly mammoth’s genome, which had 28 chromosomes; the order of genes was very similar to that of the Asian elephant. They discovered: the specimen was female; differences from modern elephants in the genes related to hair follicle development and, more broadly, hair maintenance; cooling and dehydration can preserve the molecules in their original locations.

Homelessness – From Our World in Data. Interesting…but frustrating too. I was glad that they emphasized when the data is not consistently collected…and the analysis gets very tricky.

Only One Country Is Making Progress on Electrifying Everything – Unfortunately it is not the US…it’s China. The country that electrifies most rapidly and builds the most renewables to power its electrified economy will be the most competitive economy globally.

As Arctic Thaws, New Evidence of Looming ‘Mercury Bomb’ - Scientists estimate that the amount of mercury in the atmosphere has grown sevenfold over the last 500 years, primarily from burning coal. Air currents are carrying airborne mercury toward the Arctic, where it is absorbed by plants, which then deposit the toxin in the soil. Over centuries, mercury has built up in the frozen ground, such that today, Arctic permafrost may hold more mercury than the atmosphere, the oceans, and every living organisms combined. As the region warms, melting permafrost could liberate this buried mercury.

Rare Fossils Give Clues to How Tardigrades Survived Mass Extinctions by Hitting the Snooze Button - Tardigrades are known for being some of the most resilient animals to exist, capable of surviving extreme temperatures, pressure, radiation and starvation—they can even withstand exposure to outer space. Only four known fossils of tardigrades have been found to date, and all of them are preserved in amber, or ancient tree resin; recently they were reanalyzed using confocal fluorescence microscopy. Cryptobiosis is the secret to tardigrades’ incredible resilience, and it appears to have evolved in two tardigrade linages (at least). In survival situations, these hardy creatures will expel the water from their bodies and suspend their metabolism almost completely allowing them to outlast unfavorable conditions of their environment.

Five ways the brain can age: 50,000 scans reveal possible patterns of damage - Results could lead to methods that detect the earliest stages of neurodegenerative disease. Dementia and its precursor, mild cognitive impairment, had links to three of the five patterns. Intriguingly, the researchers also found evidence that the patterns they identified could potentially be used to reveal the likelihood of more brain degeneration in the future. Other patterns were linked to conditions including Parkinson’s disease and Alzheimer’s disease, and one combination of three patterns was highly predictive of mortality.
