All commercial and public buildings have been banned from lowering their AC below 81 degrees, despite record shattering heatwaves across Europe.
As most of you know I have cancer called multiple myeloma and have had it for almost a decade now. Unfortunately medical bills are staggering, especially in the US. I am asking to reach a goal of $10,000 to help wipe out if not most of my medical debt and expenses. I have over 1,000 friends on Facebook. If each friend donated $8.00 this would help me not only reach but exceed my goal. Please consider helping:
If anyone needs proof of my diagnosis or medical debt please message me.
I have outlined my journey with cancer several years ago on Lifeboat Foundation’s blog: https://lifeboat.com/blog/2018/09/83169

How expensive is it to make a panel that uses e-ink technology? That might depend on how flexible you are. [RBarron] read about reverse engineering point-of-sale shelf labels and found them on eBay for just over a buck apiece. Next thing you know, 20 of them were working together in a single panel.
The panels use RF or NFC programming, normally, but have the capability to use BLE. Naturally you could just address each one in turn, but that isn’t very efficient. The approach here is to use one label as a BLE controller and it then drives the other displays in a serial daisy chain, where each label’s receive pin is set to the previous label’s transmit pin.
After capturing the imagination of tech insiders, the autonomous drawing tool is expanding to broader audiences and commercial uses.
Mice containing rat cells have produced rat sperm thanks to a modification technique that could be useful for conserving endangered species or creating hybrids.

Scientists overcome a natural restriction in plants that could boost yields from important food crops.

New research has opened doors to using the gene-editing tool CRISPR to stop cancer cells from dividing indefinitely.
Scientists warn that the findings aren’t yet clinically relevant but say the research raises ethical questions about the definition of death.
The electrification of heating systems could play a significant role in building decarbonization. Heat pumps are emerging as a solution.
Iranian scientists have demonstrated a multi-layer silicon nanoparticle (SNP) solar cell based on nanoparticles that are densely stacked inside a dielectric medium. They considered different SNP structures and configurations to tailor these particles as a p–n junction cell.
“This is because SNPs are assumed to be the main absorber in the cell. Thus, any distance between them reduces the absorption of incident photons,” the group said.
They considered different SNP structures and configurations to tailor these particles as a p–n junction cell. They said this kind of cell could achieve a theoretical efficiency of around 11%.
