Through a gravitational lens effect caused by a massive foreground cluster of galaxies (MACS J0138), multiple images of a perfectly aligned background galaxy (MRG-M0138) are created, including the supernova Encore it hosts. This image was captured by JWST in 2023.

🧪"In doing so, Arnold has mastered the art of a good apology: one that doesn’t veer into excusing oneself; that gives context where relevant; but accepts full responsibility and moves on".

Nobel prize winner demonstrates the best way to apologize

Unfortunately there aren’t Nobel prizes for good apologies – but Dr Frances Arnold’s words should be an example to all of us

WAChRs are excitatory opsins sensitive to indoor lighting

Hundreds of novel opsins have been characterized since the advent of optogenetics, but low experimental throughput has limited the scale of opsin engineering campaigns. We modified an automated patch-...

Their efficacy was confirmed against LIVE viruses including Ebola, Marburg, Nipah, Hendra, SARS-CoV, SARS-CoV-2 (COVID-19), AND Middle East Respiratory Syndrome (MERS).

The study has been published in Science Advances. YES, it is PEER-REVIEWED.

ABSTRACT
Viral pandemics continue to threaten global health and economic stability. Despite medical advances, the absence of broad-spectrum antivirals (BSAs) prevents rapid responses to emerging viral threats. This is largely due to the lack of universal drug targets across diverse viral families and high variability among viral proteins.
In this study, we evaluated 57 synthetic carbohydrate receptors (SCRs) for antiviral activity in cellulo using pseudotyped virus particles (PVPs) from six high-risk viruses across three families: Paramyxoviridae, Filoviridae, and Coronaviridae.
Four SCRs inhibited all tested PVPs, and their efficacy was confirmed against live viruses including SARS-CoV-2, MERS-COV, EBOV, MARV, NiV, and HeV.
Notably, SCR005 and SCR007, which exhibited minimal toxicity, significantly reduced SARS-CoV-2 infection in a severe animal model with a single dose.
Mechanistic studies suggested that SCRs bind viral envelope N-glycans, blocking viral attachment and/or fusion.
These results identify conserved viral N-glycans as promising BSA targets and establish SCRs as candidate prophylactic agents against enveloped viruses with pandemic potential.

The birds might not be so happy about this 😆

Got to love studies that were clearly conducted "for the love of the game" (“self-decapitating sea slugs”, “plants that see and use that for mimicry”, “worms that jump in the air”, aka papers you sometimes find in @currentbiology.bsky.social
) References to all of this bellow👇

It's probably the deterioration of social media (I hope) but i'm exposed to a lot less cool science. It used to feel like a new cool study is being preprinted/published every week, and lately it's rare (at least so it seems). Share a recent study that's worth knowing!
