AI ger elbilsbatterier 23 procent längre liv – utan att öka laddtiden

Så kan färgat textilavfall av polyester processas utan kemikalier
<p>En ny forskningsstudie vid H&#xF6;gskolan i Bor&#xE5;s visar att blandat, f&#xE4;rgat polyesteravfall kan f&#xE5; en j&#xE4;mn ny f&#xE4;rg utan vare sig vatten eller kemikalier. Med hj&#xE4;lp av superkritisk koldioxid omf&#xF6;rdelas f&#xE4;rg&#xE4;mnena mellan textilierna i st&#xE4;llet f&#xF6;r att avl&#xE4;gsnas, vilket kan minska ett av de st&#xF6;rsta hindren f&#xF6;r cirkul&#xE4;r textil&#xE5;tervinning.</p> <p>The post <a href="https://forskning.se/2026/05/13/fargat-textilavfall-polyester-processas-utan-kemikalier/">Så kan färgat textilavfall av polyester processas utan kemikalier</a> appeared first on <a href="https://forskning.se">forskning.se</a>.</p>
Nej, den centrala dogmen inom biologin har inte kullkastats

Kampen mellan bakteriers försvarssystem och fager pågår ständigt.&#160; – På jorden finns omkring &#8230;</p> <p>The post <a rel="nofollow" href="https://fof.se/artikel/nej-den-centrala-dogmen-inom-biologin-har-inte-kullkastats/">Nej, den centrala dogmen inom biologin har inte kullkastats</a> appeared first on <a rel="nofollow" href="https://fof.se">Forskning &amp; Framsteg</a>.</p>
Hon utvecklar teknik för Einsteinteleskopet
<p>Vaishali Adya bidrar till utvecklingen av Einsteinteleskopet (ET), en framtida europeisk anläggning för studier av gravitationsvågor med högre precision än dagens detektorer. Genom sin forskning inom kvantoptik, särskilt squeezed light, utvecklar hon teknik som minskar kvantbrus och gör det möjligt att upptäcka svagare signaler från längre bort i universum. Arbetet sker i internationell samverkan och bidrar till ett av Europas mest ambitiösa forskningsprojekt.</p>
A moment that changed me: I saw my first total solar eclipse – and its beauty shook me to my core
<p>As an astronomer, I had witnessed many celestial phenomena. But nothing prepared me for those few minutes in 2017 when the world fell silent</p><p>I have never driven with more determination than when rushing away from Shelby Park in Nashville. We had reached Davidson Street when my husband shouted: “There! There’s sunlight!” I skidded into a car park of a printing company with barely any time to spare. We jumped out of the car, put on our dark glasses, and looked at the quickly disappearing sun. It was surrounded by clouds, but a tiny sliver of light was still shining. This was 1.27pm on 21 August 2017. We had travelled all the way from London to Tennessee to experience the Great American Eclipse – an astronomical phenomenon I had never seen before.</p><p>As an Italian-born astronomer, I had always felt at a bit of a disadvantage. I have a doctorate in astrophysics, focused on collisions between galaxies. I have seen many celestial phenomena – comets, planetary alignments, fireballs, galaxies, northern lights – but not a total solar eclipse.</p> <a href="https://www.theguardian.com/lifeandstyle/2026/may/13/a-moment-that-changed-me-i-saw-my-first-total-solar-eclipse-and-its-beauty-shook-me-to-my-core">Continue reading...</a>

Getting children to eat their vegetables starts in the womb, researchers suggest
<p>Rather than bribery, or hiding carrots under ketchup, the key may be to expose foetuses to healthy flavours</p><p>It is an age-old battle with small children that most parents will recognise: please, please, eat your vegetables.</p><p>Some will read them books <a href="https://www.youtube.com/watch?v=pxF45T51W9E">with titles such as The Boy Who Loved Broccoli</a>. Others have been known to smother veg in tomato ketchup, or <a href="https://www.theguardian.com/lifeandstyle/ng-interactive/2025/oct/11/getting-kids-eat-veg-curbing-screen-time-parenting-hacks-that-actually-work">mix avocado and fruit with Greek yoghurt and call it icecream</a>.

The hunt for the next antibiotics
Nature, Published online: 13 May 2026; doi:10.1038/d41586-026-01424-9To battle antibiotic resistance, researchers are leaving no stone unturned, looking at folk traditions and harnessing AI to find new antibiotics.
Red-light therapy is all the rage — does it work?
Nature, Published online: 13 May 2026; doi:10.1038/d41586-026-01547-zThere are a multitude of red-light emitting consumer goods, but do they really do anything for your health? We look at the science behind the hype — plus, the increasing levels of obesity in lower-income countries.
An ultra-faint, chemically primitive galaxy forming in the reionization era
Nature, Published online: 13 May 2026; doi:10.1038/s41586-026-10374-1LAP1-B—an ultra-faint and tiny galaxy that formed in the reionization era and is strongly magnified by gravitational lensing—is chemically primitive and hosts very few stars in an otherwise dominant dark matter halo.
Efficient robot navigation inspired by honeybee learning flights
Nature, Published online: 13 May 2026; doi:10.1038/s41586-026-10461-3A highly efficient navigation strategy taking inspiration from the visual learning flights of honeybees is described, which enables drones to quickly return from longer flights by means of path integration and uses a neural network as a view memory to reach the home location.
Sustaining microglial reparative function enhances stroke recovery
Nature, Published online: 13 May 2026; doi:10.1038/s41586-026-10480-0Reparative microglia persist in the brain after stroke but become dysfunctional through ZFP384-mediated mechanisms; however, this process can be mitigated by targeting Zfp384 using therapeutic antisense oligonucleotides.

Nature, Published online: 13 May 2026; doi:10.1038/s41586-026-10494-8Single-cell transcriptomics combined with morphological and ecological data show that the rapid evolutionary radiation of cichlid fishes in Lake Tanganyika was accompanied by dietary specialization across multiple layers of biological organization.

Nature, Published online: 13 May 2026; doi:10.1038/s41586-026-10506-7Government-controlled media influences the output of large language models via their training data, and models queried in the languages of countries with lower media freedom show a stronger pro-regime valence than models queried in the languages of countries with higher media freedom.
Enamel proteins from six <i>Homo erectus</i> specimens across China
Nature, Published online: 13 May 2026; doi:10.1038/s41586-026-10478-8Palaeoproteomic analysis of ancient enamel proteins extracted from Middle Pleistocene Homo erectus specimens from the Zhoukoudian, Hexian and Sunjiadong sites in China suggests that they are a new genetic monogroup, and super-archaic introgression in Denisovans is likely to have originated from H. erectus.
