Researchers have found a way for green fuel energy by using proton conducting. The findings can be used in biological devices. [A proton conductor is an electrolyte in which H+ are the primary charge carriers]. Researchers explored how proton conduction was affected in styrene-based polymers at diffirent concentrations of carboxylic acid, a proton-donating organic acid found commonly in biomaterials. The research team synthesized polymers with different concentrations of carboxylic acid and prepared them as thin films and investigated the interfacial transport properties. In the polymers free COOH groups were more abundant at higher concentrations, and cyclic dimer COOH groups were more abundant at low concentrations. High COOH concentrations were more conducive to internal proton transport while lower concentrations favored interfacial transport. At high concentrations the free COOH groups generated more hydrogen bonding networks, facilitating conduction. A higher number of free COOH groups on the interface led to higher interfacial . The  research may contribute to developing bio-conductive materials for biological devices involved with  and eco-friendly fuel cells.

Starwatch: track down the large but overlooked Boötes, the herdsman
Stars in this constellation were mentioned by the ancient Babylonians and later by Ptolemy This week it's time to track down a large but easily overlooked constellation. Boötes, the herdsman, is an ancient constellation that was catalogued by the Greek astronomer Ptolemy in the second century. References to the stars in this constellation date back even further, however, to the ancient Babylonian

Gender stereotypes still hold true for youth and types of political participation
Gender roles absorbed early on have shaped today's youth regarding their involvement in politics, in line with traditional stereotypes, concludes a new study, conducted amongst adolescents and young adults aged between 15 and 30 in Italy. The researchers report that young males are more likely to engage directly with politics and take part in protests, while their female counterparts would rather

Beer byproduct mixed with manure proves an excellent pesticide
A new study published by the open access publisher Frontiers has demonstrated that beer bagasse and rapeseed cake can be used as effective biodisinfestation treatments to reduce populations of soil parasites and increase crop yields. Researchers demonstrated that using these organic treatments in soils significantly reduced root-knot nematodes and boosted beneficial soil populations, as well as re

What is stopping the internet from becoming a free service paid by tax?
In the modern world, internet is just as important as a library. I never had access to the internet when I was in school (back in 2007-2012) and I found my work noticeably harder as a result. If I wanted to use the internet, I had to either go to the library or stay back at school. Libraries are already funded by taxes, why not the internet? submitted by /u/ToesyToeNails [link] [comments]

What do you think the early period of Mars colonization will look like?
It could go so many different ways. I recently found this awesome time lapse video of the first 10,000 days on Mars starting with SpaceX launching 5 cargo Starships to Mars in 2024. So basically, it should look like this: cargo and robotic crew arrive, with robots collecting resources and landscaping the terrain for future landings The first batch of astronauts arrive – architects, scientists, en

The Real Twist of Mare of Easttown
This article contains spoilers through the entirety of Mare of Easttown. Mare of Easttown is a strange name for a prestige television show: clunky, nondescriptive, homonymic. ("So she's the mayor?" people might ask if you recommend the series, and in a way, she is.) "Mare" is short for "Marianne," the latter of which befits Kate Winslet's scruffy, vape-slurping Delaware County detective about as

Is the universe infinite?
The question of whether the universe is finite or infinite has not yet been resolved. The size of the universe is linked to understanding its shape and the limits of our observations. New studies and going deeper into space will help us answer if the universe is infinite. Does the universe keep extending endlessly into the abyss of space, or does it have a defined end?

Egypt bets on ancient finds to pull tourism out of pandemic

I'm Not Scared to Reenter Society. I'm Just Not Sure I Want To.
This post-pandemic summer is evidently expected to be one long orgiastic reunion, after which, once that's out of our system, it's back to work, back to school, to what we used to call "normal." And if the pandemic had ended, say, last June, after a couple months of lockdown, we probably would've returned to our lives with relief and jubilation. But after a year in isolation, I, at least, have go

Sperm may play bigger role in pregnancy than we thought
The following article was originally published on our sister site, Freethink. New research suggests that sperm play a bigger role in pregnancy than previously believed, not only fertilizing the egg, but also "persuading" the female body to accept it. Revisiting sex ed: Human reproduction typically starts with sperm traveling via seminal fluid to an egg and fertilizing it. That creates a zygote, w

The bizarro "future" which isn't the future (from a '90s perspective)

Thoughts on which metaverse will come out on top?
Been half-obsessed with the concept of the Metaverse ever since I read Snow Crash five years ago. Turns out that there's already a lot of work being done by companies building up their digital ecosystems and vying for users, but it's hard to tell who will come out as the clear leader. My initial thoughts are with Facebook and Oculus because of the hardware advantage, but maybe it's Roblox, Minecr
