Microplastics reduce soil fertility and boost production of a potent greenhouse gas, study shows
More than 90% of plastic waste ends up in the soil, where it breaks down into microplastics that are invisible to the naked eye. Microplastic pollution of the soil poses a severe threat to soil health as it can harm essential microbial communities and reduce crop yields. The presence of these tiny plastics may also worsen climate change by boosting the production of greenhouse gases, according to a new study published in Environmental Science & Technology.

"Thats not to say there haven’t been growing pains. When a great steak comes out of the microwave I get really excited. But more than half the steaks that come out of the microwave get sent back by the customer. To solve this problem I now run ten microwaves in parallel cooking ten steaks. One out of the ten steaks will most likely be good. The number of microwaves has required me to upgrade my restaurant’s electrical system and I now have a small nuclear reactor installed in the parkin…

Novel research reveals thriving microbial life in trees
There's a thriving community of diverse microbes living in tree wood, a new study led by a Yale School of the Environment team of scientists has found. A single tree hosts about one trillion bacteria in its woody tissue.

Green Roofs Filter Microplastic From Urban Rainfall, Study Finds | Happy Eco News
Green roofs filter microplastic from urban rainwater by capturing up to 97.5% of plastic particles during rainfall, according to a new study. Most particles stay in the soil, helping reduce pollution in city waterways. While challenges remain, this adds another reason to expand green roof infrastructure in urban areas.

This is the third full build iteration of my miniature #QRP unun supporting both EFHW and "random wire" antennas. At this point, it is still fiddly to build, but I'd expect an experienced #HamRadio DIY / homebrew enthusiast to find the build not terribly difficult.
There's nothing…

Photograph of tiny QRP unun showing size of overall assembly including integrated coax. BNC connector for scale! The corners of the box have M3 countersink screws. There are three knobs on the side; a purple knob for the counterpoise connection, and red (high voltage!) knobs for "random wire" and end-fed half wave connections,
Inside view of unun autotransformer showing construction details, next to a ruler for scale, showing that the entire box is less that 3.5 cm across. There is a half-inch ferrite in the box, wrapped in kapton tape, with a 14-turn autotransformer wrapped around it. There are three M3x8 brass screws through the edges, connected to the transformer with ring terminals. The screws are held in place by captive nuts. An RG316 coax segment comes in through the side of the box to feed the autotransformer…
Side view of assembled unun, without a terminal knob, showing how thin it is. The letter "R" is visible on the side of the box, indicating that the adjacent terminal is intended for a "random wire" antenna.
A photo showing a comparison of this version of the unun design to the previous iteration, configured for deployment. The previous iteration was built on a SO-239 bulkhead connector, with a PL-259-to-BNC connector attached.

Ein kleiner #Handrekorder mit guten #Mikrofonen ist ein praktischer Begleiter für #Naturliebhaber.
Er ermöglicht hochwertige Tonaufnahmen unterwegs, zum Beispiel von Vogelgesang. Mi…

Ein Zoom H1 Rekorder liegt auf einem Holzboden. Der kompakte, schwarze Audiorekorder hat ein kleines Display und Bedientasten an der Seite. Oben befindet sich ein Mikrofon mit einem großen, flauschigen Windschutz in Grau und Weiß, um Windgeräusche bei Außenaufnahmen zu minimieren. Der Rekorder verfügt über eine Aufnahme-Taste sowie Anschlüsse für Kopfhörer und Line-Out. Er ist ideal für Outdoor-Audioaufnahmen, Interviews oder Naturgeräusche.

Revolutionary Study Shows Plants That Remove Microplastics Work Better Than Current Technology | Happy Eco News
Plants that remove microplastics from water could revolutionize treatment methods. Scientists discovered okra and fenugreek extracts capture up to 90% of plastic particles, outperforming synthetic chemicals. These natural, biodegradable alternatives cost less than industrial polymers while avoiding toxic additives, offering safer water treatment for communities worldwide.

Today's #HamRadio adventures... My oldest and I went to do #POTA together. He's a technician, and 10m was mostly dead where we were, except for a booming SSB QSO with California to a club doing the CA QSO party, so he didn't get his 10 today.
I started running CW QRP (5W) on on 1…
