The ancient practice of 'good fire' is reviving Nebraska's birds, bears and berries - In its original shape, the once wide, but relatively shallow Platte River provided an open space for the (sandhill) cranes to roost, while also keeping an eye on predators. These four-to-five-foot tall birds with wingspans of six-to-seven feet found abundant plants and insects to eat on the Nebraskan prairies. Lightning strikes brought occasional wildfires, which cleared out dead material and refreshed native plant life. Fire suppression is not always a good thing…

Giant Slab of Bog Butter Recovered in Ireland – Nearly 50 pounds! It is being analyzed by the National Museum of Ireland. It would be interesting to know how long it had been in the bog.

How Agroforestry Could Help Revitalize America’s Corn Belt – 8,200 hazelnut saplings growing with flocks of chickens in narrow grass paddocks between the rows of fledgling trees…. By combining food-bearing trees and shrubs with poultry production it is an example of agroforestry — an ancient practice that intertwines annual and perennial agriculture. Other forms include alley cropping, in which annual crops including grains, legumes, and vegetables grow between rows of food-bearing trees, and silvopasture, which features cattle munching grass between the rows. An acre of land under agroforestry can sequester five metric tons of CO2 annually, versus one ton for an acre of corn or soybeans. As the region’s vast corn and soybean operations continue hemorrhaging soil and fouling water and climate change proceeds apace, they may find themselves looking for new directions sooner than later.

Humans Pollute the Environment With 57 Million Tons of Plastic Each Year - Uncollected waste is the biggest source of plastic pollution, with at least 1.2 billion people living without waste collection services forced to ‘self-manage’ waste, often by dumping it on land, in rivers, or burning it in open fires. This “self-managed” plastic waste makes up more than two-thirds of the modeled plastic pollution. The study also calculated the largest contributors to plastic pollution in the world: India is in first place, producing 10.2 million tons a year; Nigeria is in second; Indonesia is in third; and China—which had been ranked in first place according to other models—instead comes in fourth. The U.S. ranks 90th, with more than 52,500 tons of plastic pollution produced annually.

One of world's fastest ocean currents is remarkably stable - There is growing scientific and public interest in the global Atlantic Meridional Overturning Circulation, or AMOC, a three-dimensional system of ocean currents that act as a "conveyer belt" to distribute heat, salt, nutrients, and carbon dioxide across the world's oceans. This study found that Florida Current, the beginning of the Gulf Stream system and a key component of the AMOC, has remained stable for the past four decades. Understanding the state of the Florida Current is very important for developing coastal sea level forecast systems, assessing local weather and ecosystem and societal impacts.

Growth of Solar Continues to Defy Predictions - The world is set to install a third more solar capacity this year than it did in 2023, surpassing forecasts by both industry experts and independent analysts. China is driving the bulk of the growth. Through May, India installed more solar capacity than it did in the whole of last year, and in the U.S., new tax breaks are giving the industry a significant boost. Solar manufacturing has jumped fourfold since the passage of the Inflation Reduction Act in 2022.

Birds Form Surprising Relationships with Other Avian Species During Migration - The researchers found that songbirds tended to show up together rather than avoid each other. American redstarts and magnolia warblers reliably appeared together in the researchers’ nets in spring and fall. The same thing happened with ruby-crowned kinglets and white-throated sparrows. The presence of other birds with similar foraging behavior or similar food preferences may signal to newcomers where the good habitat is, helping them refuel more quickly.

Residents in San Joaquin Valley breathe chemical pesticides - A new study found 22% of adults and 10% of children who participated in an air-quality study in California's San Joaquin Valley were breathing detectable levels of pesticides. Participants in this study served as citizen scientists, going about their normal days while wearing the backpacks to collect the samples.

Creative ways communities are reducing food waste – Returning oyster shells to the water in Alabama, collecting food waste for composting in almond orchards in California, gleaning fruit at the end of the season to supply the needy in New Hampshire-Massachusetts, and using underused land to grow free food in Washington.

Only Two US Metro Areas Are Affordable for Homebuyers - Before the Covid-19 pandemic, 20 U.S. states were considered affordable home-buying markets for most households. Today, just two metro areas remain ‘affordable’ by that definition issued by the National Association of Realtors — and no entire states fit the bill. The two metro areas are Youngstown and Akron, Ohio. Home prices have increased by 47% nationwide just since 2020, according to a June report by the Harvard Joint Center for Housing Studies. A major factor is that there aren’t many homes for sale.

Federal flood maps are outdated because of climate change – The challenge of record rainfall events becoming more common and resulting in flooding of places not seen as vulnerable previously.

Hundreds of Monumental “Kites” Spotted in Arabian Desert – Low stone walls that could be enclosures used to guide game for capture/slaughter as early as 8000 BC.

The mystery of the human sacrifices buried in Europe's bogs – Sacrifices or maybe burial for anyone that died mysteriously or unnaturally. I remember being fascinated about the ‘bog bodies’ back in 1970s…buying the book about them by P.V. Glob.

Diet change may make biggest impact on reducing heart risk in people with hypertension – Too bad that the study also found “the availability and affordability of healthy food sources does not easily allow people to follow the DASH diet.” Diets are hard enough to sustain without those extra challenges.

Despite its innocently furry appearance, the puss caterpillar’s sting is brutal – The don’t look vicious….but the hairs have poisonous barbs! There are other caterpillars that also have ‘hairs’ and can deliver painful stings – like the saddleback caterpillars. In general…I avoid handling caterpillars with hairs or bristles!

Cancers in adults under 50 on the rise globally – Earlier detection could account for some of the increase…but it is unlikely to be the sole reason. 8 of the 14 cancers on the rise are related to the digestive system. With those types of cancers, the hypothesis is that the food we eat has changed dramatically and has changed our microbiome composition…and eventual these changes influence disease risk and outcomes. There is still a lot of work to be done but it appears that the drastic rise in early onset cancer began around 1990.

The biggest myths of the teenage brain – Hopefully some of these findings will be factors in decision making for things like high school hours and how to help teenagers better understand themselves.

NREL Study Identifies Opportunities & Challenges of Achieving the U.S. Transformational Goal of 100% Clean Electricity by 2035 – No single solution….having multiple pathways to the goal is probably a good thing.

Arctic lakes are vanishing a century earlier than predicted – Warmer temperatures and more abundant autumn rainfall have caused permafrost around/beneath Arctic lakes to melt…and the lakes shank between 2000 to 2021. The reduction in lakes impacts migratory birds and other wildlife…and human communities in the Arctic.

Fall Foliage Prediction Map – My road trips this fall will offer many opportunities to see fall foliage: 1st week in October in Michigan and Canada, the rest of October around Missouri, then Texas later in October into November.

An effective new treatment for chronic back pain targets the nervous system – A 12-week course of sensorimotor retraining had a positive effect and participants reported improved quality of life one year later (i.e., the relief was lasting). Hopefully the results can be replicated, and the treatment applied to a broader population. There are a lot of people with chronic back pain!

New Study Links Cat Hormones and Gut Microbiomes to Their Social Behavior – Hard to resist a cat story!

Millions of Americans have long COVID. Many of them are no longer working – 4 million full-time equivalent workers out of work because of long COVID (conservative estimate…and that 2.4% of the US working population). There is a push to provide accommodation in the workplace but some of the symptoms are so severe that the person cannot perform the work they did before and maybe too disabled to work at all. No wonder unemployment is low, and some jobs are not finding applicants. Because long COVID is new, it is unclear when, or if, this population will recover enough to re-enter the workforce.

Arche Roach: the great song man, tender and humble, who gave our people voice – An obituary – and history of aboriginal people in Australia over the past century or so.

The promise and danger of Scotland's bog – 80% of the UK’s peatlands are degraded and in deteriorating condition. They store a lot of carbon…motivating restoration efforts. It takes decades to reverse damage done in a short time by a few ditches and a grid of planted saplings.

New molecule may prevent age-related diseases and increase life expectancy and wellness – A group of molecules that enable cells to repair damaged components has been identified….and efficacy was demonstrated in a model organism. The researchers and Hebrew University’s tech transfer company are moving toward pre-clinical studies.

Parts of the moon have stable temperatures fit for humans – Pits and caves that stay roughly 63 degrees Fahrenheit! There are still big challenges for living on the moon: growing food and finding sufficient oxygen, for example

Coming wave of opioid overdoses 'will be worse than it's ever been before' – Fentanyl and carfentanil…combined with methamphetamines and cocaine. The accelerated rates of overdoses are happening everywhere according to a Northwestern Medicine study.

Inside King Tut’s Tomb – New research using the tomb walls to understand the real-world turmoil cause by the death of the young king.

Cocoa shown to reduce blood pressure and arterial stiffness in real-life study – Cocoa flavanols only decrease blood pressure if it is elevated! I enjoy my morning dark chocolate (70+% cocoa) squares…a healthy way to begin the day!
