5 New Year’s Resolutions for Your Garden – All 5 are good ideas! I am on my second year of ‘turn an area of turf grass into a native garden.’ If the native trees/shrugs I planted last fall survive…it won’t be hard at all to reduce some turf in 2025. I haven’t used pesticides since we moved to Missouri and we already use electric or hand-powered tools. We have a bird bath. I am not at 70% native plants – yet. That one could be hard although I am going making some progress; I will eliminate a Japanese barberry and forsythia in the spring to make way for more native plantings.

Best of 2024 – Square Meter Prairie Photos – Macro photographs from The Prairie Ecologist.

Scientists Unlock the Secrets of Crocodile Skin and Its Irregular, Mystifying Patterns – Research that discovered that the uniqueness of crocodiles’ head scales is driven from mechanical processes, such as growth rate and skin stiffness, rather than gene expression.

The Case of The Missing Cinders from Yellowstone's Cinder Pool - What happened to the cinders that used to float atop Cinder Pool in the One Hundred Spring Plain area of Norris Geyser Basin? Cinder Pool was one of the few known cinder-producing pools in the world. Using historical water chemistry data, the pH (4.1 ± 0.2) of Cinder Pool was fairly constant from 1947 to 2015, and the sulfate concentration was relatively low (80 ± 20 mg/L). Cinders were last observed in 2018. By April 2019, the pool was lacking cinders and had become significantly more acidic, with the pH dropping to 2.6 and the sulfate concentration increasing to 350 mg/L. Cinders were no longer being generated, and the appearance of the pool changed drastically. Dynamic Yellowstone!

Animals That Turn White in Winter Face a Climate Challenge – There are some snowshoe hares that stay brown during winter…and they may be surviving better in areas that are now getting less snow in the winter. Animals that are adapted to winter by turning white…might find the adaptation a hazard if there is no snow!

Natural disasters killed thousands around the world, caused billions in damage in 2024 - In the United States alone, there have been at least 24 weather-related disasters that caused more than $1 billion in damages each according to the National Oceanic and Atmospheric Administration. Since 1980, the annual average number of events is 8.5. When counting the most recent five years alone -- 2019 through 2023 -- that average increases to 20.4 events per year. The cost of climate change is increasing around the world…impacting everyone.

The global divide between longer life and good health - Life expectancy, or lifespan, increased from 79.2 to 80.7 years in women and from 74.1 to 76.3 years in men between 2000 and 2019, according to WHO estimates. However, the number of years those people were living in good health did not correspondingly increase. The average global gap in lifespan versus healthspan was 9.6 years in 2019, the last year of available statistics. That represents a 13% increase since 2000.

Scientists Just Dissected the World’s Rarest Whale in New Zealand - Only seven spade-toothed whales have ever been identified, and the species has never been seen alive. When a 16-foot, 3,000-pound carcass washed ashore on the South Island of New Zealand in July; it was in remarkably good condition and appeared in a region of New Zealand that allowed researchers to perform the first-ever dissection of the species. The research and dissection process was under the guidance of both scientists and members of local Māori tribes on the South Island. Some discoveries: vestigial teeth, 9 stomach chambers, and head trauma was cause of death.

Interior Department Signed 69 Tribal Co-Stewardship Agreements In 2024 - The agreements cover a range of ways designed to bring tribes into management of public lands. That includes efforts by Interior to expand bison habitat and entering into bison co-management agreements with tribal leaders, shifting historic preservation responsibilities from federal agencies to tribal agencies, carefully weighing the impact of federal agency action on sacred sites, and expanding and reforming self-governance as part of the Practical Reforms and Other Goals to Reinforce the Effectiveness of Self-Governance and Self Determination for Indian Tribes (PROGRESS) Act.

Study likely to change standard of care for deadly strokes - Endovascular therapy, or EVT, -- a minimally invasive surgery performed inside the blood vessels -- is 2 ½ times more likely than standard medical management to achieve a positive outcome after vertebrobasilar stroke that affects the back of the brain, including the brain stem.

Gleanings of the Week Ending January 8, 2022

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.

2021 Year In Review: Top Stories From The National Parks – Lots of perspectives in these ‘top stories’ – lots of challenges but some room for hope in 2022.

Earth in 2021 – A 3-minute video summary from NASA….lots of before and after catastrophic events. The text in the post has a short description of the events in the video.

Top 25 birds of the week: Birding! – Bird photographs…always a great look.

Stopping dementia at the nose with combination of rifampicin and resveratrol – The research was done in mice…they started preparation for human clinical trials in November. If it is effective in humans and can be produced/distributed economically, it could be a boon for aging populations around the world.

Saguaro National Park – A place I visited frequently while by daughter was in Tucson for graduate school. It’s interesting how they are monitoring the keystone species in the park…concern is that fewer young saguaros are surviving these days.

Climate-driven weather disasters inflicted billions in damage in 2021, study says – The cost of climate change already is impacting economies around the world….doing something to reduce/mitigate climate change is quickly becoming the option that makes the most economic sense for everyone.

Poison Ivy – You don’t want to touch it…but it’s best left alone when it’s growing in a place where people are unlikely to contact it. Its berries provide food for birds in the winter, it does not hurt the trees it climbs, and its leaves turn red in the fall.

Chalk steams: why ‘England’s rainforests’ are so rare and precious – This article brought back memories of wading in chalk bottomed creeks in the Dallas, TX area when I was teenager. I don’t remember much about the plants and animals…more about the fossils weathering out of the chalk.

2021 Year In Review - Another Year of Photography During The Pandemic – Beautiful places…and some little photography lessons too.

The year in chemistry: 2021’s biggest chemistry stories – 2021 was quite a year for big chemistry stories! Several of them are likely to have high impact for years to come.

Neandertal slaughters · john hawks weblog – Analysis of 5 sites indicates that Neandertals were excellent tacticians, casual executioners, and discerning diners.

Rare Gemstone Hidden in Ancient Teeth Reveals a Surprising Truth About Medieval Women – Lapis Lazuli found in the remains of a middle aged woman’s teeth and jaw. She was buried in an all-female monastery in Germany sometime around 1000-1200 CE. The researchers concluded that she most likely was painting with the pigment (licking the end of the brush while painting) creating manuscripts.

More solutions needed for campus hunger – A new report states that 9-50% of America’s college students face food insecurity…and that does not include graduate students. There are some programs that could help but often the students are not aware of them…and there may be enough stigma attached to them that students shy away. These are young adults that need adequate nutrition to continue their schooling and growth into adulthood.

Image of the Day: What We've Dumped | The Scientist Magazine® - Yuck! Stuff that washed up on 12 shoreline sites on barrier island along the US Gulf Coast…and it’s all stuff that people put in the water.

Two billion birds migrate over Gulf Coast -- ScienceDaily – Combining eBird observational data helps translate radar data into estimates of bird numbers. The peak time was April 18-May 7. The highest activity is over the west Texas Gulf Coast (Corpus Christi to Brownsville).

US Cancer Death Rate Dropped for 25 Years Starting in 1991 | The Scientist Magazine® - Down 25% over 27 years…a positive trend.  But there are still issues of race and socioeconomic inequality when it comes to prevention and treatment. The trend is not good for obesity related cancers; they are on the rise.

Top 25 Wild Bird Photographs of the Week: December – National Geographic Society Newsroom – I always like bird pictures.

Natural Disasters Caused $160 Billion in Damage in 2018 - Yale E360 – It did seem like there were a lot of disasters last year: fires in California, Hurricanes Michael and Florence…and that’s just the ones in the US.

Medical marketing has skyrocketed in the past two decades, while oversight remains limited -- ScienceDaily – I have been suspicious of medical marketing (particularly ads on television) for some time. The study seems to show that state and federal regulators are overwhelmed.

Image of the Day: Geckos on the Run | The Scientist Magazine® - It must take a lot of energy for the gecko…but it can indeed run across the surface of the water.
