Gibt es eine gute aufblasbare oder sich selbst aufblasende #Matratze, die sich zum Mitnehmen klein verpacken lässt und auf der ein rückenempfindlicher Ü50 Erwachsener 10 Tage am Stück gut schlafen kann? Kann auch was kosten, Hauptsache klein zum Mitnehmen und rückenfreundlich
Edit: Matratze zum Zelten hab ich schon, die ist mir zu schmal und zu dünn, suche wirklich „Bettersatz“

For anyone who cares about the environment - be it climate, toxics, endangered species, biodiversity, air quality, water quality- here's a chance to support removing Lee Zeldin, the EPA Administrator who is cheerfully removing all the environmental protections so many have worked so hard to put in place.
Please sign this petition to remove him from office:

Anti-abortion activists have been trying to convince the broader public that medication abortion is dangerous for years,
but their latest argument is a decades-old asinine conspiracy theory.
In a June 18 letter to Environmental Protection Agency (EPA) Administrator Lee Zeldin,
25 House Republicans asked the agency to study the alleged
“byproducts” of Mifepristone
(the first medication administered in a medication abortion regimen)
in water systems.

Küchenmaschine defekt. Ohne dass sie läuft, britzelt es und macht Puff. Sicherung fliegt raus.
Die Bosch MUM ist sicher 20 Jahre alt und läuft täglich. Aber ich mag es nicht, Dinge wegzuwerfen und zudem haben wir zahlreiches Zubehör, bishin zur Steinmühle.
Also aufgeschraubt, Fehlersuche.
Da der Motor nicht lief, muß das Problem in der Zuleitung stecken. Das Kabel ausgebaut, aber kein Kurzschluss zu erkennen.
und - sind mit Steckern an der Platine befestigt. Also aufs…

„Na gut, wenn sich vielleicht kein US-Verleih für meinen Film finden lässt, auch nicht die United Artists, die er 1919 mitgegründet hat, dann mache ich einfach Folgendes:
Ich miete überall in den USA große Zelte und lasse dann den Film in den Zelten zu einem geringen Eintrittspreis vorführen.
Chaplin geht volles Risiko.
Er finanziert den Film aus eigener Tasche, investiert zwei Millionen Dollar seines Privatvermögens.“

Abstract: The discovery of optical frequency combs (OFCs) has revolutionised science and technology by bridging electronics and photonics, driving major advances in precision measurements, atomic clocks, spectroscopy, telecommunications, and astronomy. However, current OFC systems still require further development to enable broader adoption in fields such as communication, aerospace, defence, and healthcare. There is a growing need for compact, portable OFCs that deliver high output power, robust self-referencing, and application-specific spectral coverage. On the conceptual side, progress toward such systems is hindered by an incomplete understanding of the fundamental principles governing OFC generation in emerging devices and materials, as well as evolving insights into the interplay between soliton and mode-locking effects. This roadmap presents the vision of a diverse group of academic and industry researchers and educators from Europe, along with their collaborators, on the current status and future directions of OFC science. It highlights a multidisciplinary approach that integrates novel physics, engineering innovation, and advanced researcher training. Topics include advances in soliton science as it relates to OFCs, the extension of OFC spectra into the visible and mid-infrared ranges, metrology applications and noise performance of integrated OFC sources, new fibre-based OFC modules, OFC lasers and OFC applications in astronomy.

Nearly two dozen states are suing the Trump administration
over its cancellation of a $7bn grant program aimed at expanding solar energy in low-income communities.
In a statement on Thursday, California’s attorney general,
Rob Bonta, announced two lawsuits
by a group of states that received grants under the Environmental Protection Agency’s
Solar for All program.
The EPA’s administrator,
Lee Zeldin,
announced the termination of the program in …
