Vermont plastic bag use dropped 91% following ban, researchers find
In the midst of 2020 COVID measures, another change took place in Vermont: A law went into effect banning businesses from offering plastic bags to customers, with paper bags only available for a fee.

fly_hemibrain: Fly hemibrain (2020)
A synaptic map of the hemibrain connectome of fruit fly Drosophila melanogaster. Nodes are neurons, and edges are synaptic connections, traced individually from brain image sections using EM reconstruction techniques. Neurons are labeled by their type. Edges are annotated by the connection strength between the neurons.
This network has 21739 nodes and 4259624 edges.

When DJ Cummerbund made this mashup in 2020 I did take notice that one of the acts was "BTS Skytrain" but I just assumed this was just some strange relative of Korea's BTS.
Shame on me for not knowing or at least spotting that it was an actual promotional video for Bangkok's mass transit system - which also means I was not able to tell the difference between Thai and Korean people.
My only defence is that they are wearing masks but still…

🔥 In den westlichen #USA waren Menschen zwischen 2006 und 2020 an 130 Millionen Personentagen gleichzeitig extremer #Hitze und #Rauch durch

Huh. In Philip P. Peterson's "Transport" SciFi series, the 5th book (currently only available in German), there was a "plague" in the 2020s that grounded all space missions for a long while. That book was published 15.05.2020, #COVID became "public" December 2019, only 6 months ago - kinda short publishing period. So either Peterson quickly rewrote that part and pu…

(2020) Want to reduce the carbon footprint of your food? Focus on what you eat, not whether your food is local #environment

You want to reduce the carbon footprint of your food? Focus on what you eat, not whether your food is local
“Eat local” is a common recommendation to reduce the carbon footprint of your diet. How does the impact of what you eat compare to where it's come from?

Impact of the WHO's 90-70-90 Strategy on HPV-Related Cervical Cancer Control: A Mathematical Model Evaluation in China
In August 2020, the World Health Assembly approved the Global Strategy to eliminate cervical cancer, marking the first time that numerous countries committed to eliminating a form of cancer. China introduced the HPV vaccine in 2016 and has made significant advancements in both prevention and treatment strategies. However, due to the relatively late introduction of the vaccine, the burden of cervical cancer in China continues to rise. In light of this, we develop a compartmental model to assess …

A note on multi-transitivity in non-autonomous discrete systems
This paper is concerned with some stronger forms of transitivity in non-autonomous discrete systems$(f_{ 1,\infty})$ generated by a uniformly convergent sequence of continuous self maps. Firstly, we present two counterexamples to show that Theorem 3.1 obtained by Salman and Das in [Multi-transitivity in nonautonomous discrete systems Topol. Appl. 278(2020)107237] is not true. Then, we introduce and study mildly mixing in non-autonomous discrete systems, which is stronger than mixing. We obtain …

A State of the Art on Recent Progress and Emerging Challenges on Energy Transfer Between Vibrating Modes Under an External Mechanical Force With Time-Varying Frequency From 2020 to 2025
In this paper, we discuss an example of current importance with a future perspective in engineering, in which excitation sources always have limited power, limited inertia, and their frequencies vary according to the instantaneous state of the vibrating system. Practical examples of non-ideal systems are considered. The most common phenomenon for this kind of system is discussed. The period considered is from 2020 to 2025. The specific properties of various models are also discussed. Directions…
