This #WorldHepatitisDay, we recognize the power of scientific discovery to change lives.
Rockefeller's Charles Rice (@RiceLaboratory) was awarded the 2020 Nobel Prize in Physiology or Medicine for discoveries that led to the identification and control of the hepatitis C virus.

Diversity and distinctive characteristics of the global RNA virome in urban and peri-urban environments nature.com/articles/s41467-0…
Maria Alejandra Sierra retweeted
Our new study maps the urban RNA virome across 2,922 samples, 102 cities and 31 countries. We identified 54,945 RNA viruses, with 77% previously unobserved, and two candidate phyla. Proud to share this work with the @MetaSUB team, @mason_lab and many more!

Online now: Brain endothelial cells orchestrate a neuroprotective antiviral state in the CNS in response to peripheral viral pattern sensing dlvr.it/TTKcV6
Shedding some light onto how viruses get in the CNS! Thank you to everyone involved @tyler_lewy @alex_lercher @RiceLaboratory
Great work from @asierra93 and the Rice lab at @RockefellerUniv in our new paper "Brain endothelial cells orchestrate a neuroprotective antiviral state in the CNS in response to peripheral viral pattern sensing" in @ImmunityCP doi.org/10.1016/j.immuni.202…, where we saw inter-organ antiviral crosstalk protected against severe encephalitis, caused by a range of neurotropic viruses across Orthoflaviviridae, Togaviridae, and Orthoherpesviridae

Congratulations @rookisaacman! Excited for this new mission on Earth!
Replying to @rookisaacman @realDonaldTrump
Thank you for your service, and we (scientists, clinicians, researchers across public and private realms) are elated to support you. My phone is full of messages from excited teams, our lab lab is ready to jump in!

Women lose >90% of their #eggs by their mid-30s, with persistent #DNADamage driving this loss. But why isn’t this damage repaired?
Our new work in @CurrentBiology, led by @ninadini_sharma, reveals the causes of high DNA damage in aged oocytes.🧬💥

What brought our Ambassadors into the hidden world of the microbiome? How did they become interested in biology? What excites them about their research?
In this NMDC Snapshots series, I talk more about my professional journey in science! Check it out.
Our 2024 Ambassadors study it all - from marine nematode and coral microbiomes, honeybee microbiomes, and soil microbiomes to the gut microbiomes of migratory birds. Read more about them in our series #NMDCsnapshots microbiomedata.org/nmdc-snap…
I am very happy to represent the National @MicrobiomeData Consortium at the International @metasub Meeting in Tokyo, Japan, to talk about the importance of data standards in microbiome research. – at Tokyo-to, Japan

We are humbled to have our lab's work featured this week on the cover of @Nature (below), with many, many people to thank.
First, the stellar crew of @inspiration4x, @rookisaacman, @ArceneauxHayley, @ChrisSembroski, @DrSianProctor, who donated time, blood, fluids, and sweat for the mission. These data were the foundation of the Space Omics and Medical Atlas (SOMA), expanding upon the findings from @StationCDRKelly & @CaptMarkKelly in the NASA Twins Study and enabling an unprecedented look the human body (and its microbes) in space.
Second, thanks to many science teams , especially co-leaders for the SOMA effort @AfshinBeheshti, @EliahOverbey, @cemmeydan, Chris Jones, @mathiasbasner, @KeithSiew, Stephen Walsh, @joseph_borg_ , & Susan Bailey, the I4 mission science leads Frederic Zenhausern, Mark Shelhamer, Eric Bershad, @aesargsyan, @7irz, @DoritPhD, @EUrquietaMD, Ashot Sargsyan, Doug Ebert, Mathias Basner, and leadership from @IwijnDeVlaminck, @Astro_Kate7, @trialx, @LabMelnick, @nebula_rd, @FathiKarouia, @giacomello_lab, Scott Smith, Sara Zwart, @SpaceLuisZea, and many more.
Third, the amazing med-ops and mission teams at @spaceX and @NASA, especially @jmat_, @astro_anil (now at NASA), Sean Mullane, Seth Stravers Tigchelaar, Steven Levitte, & Marissa Rosenberg, plus all the support teams in the planning and logistics stages before, during, and after the missions.
Fourth, the labs at @WeillCornell who worked for several years on the papers and data portals, especially @EliahOverbey, @KJangkeun @BradenTierney @krista_ryon @JIWOONPARK_ @mjdmackay @asierra93, @ChrisRChin, & Dan Butler, Sebastian Garcia Medina, Namita Damle, Deena Najjar, Kirill Grigorev, Karolina Sienkiewicz, Laura Patras, Remi Klotz, Veronica Ortiz, Annalise Schweickart, Theodore M. Nelson, Gabriel Deards, Jonathan Foox, Craig Westover, Chandrima Bhattacharya, Serena Lucotti, Jacqueline Proszynski, Marissa Burke, Ashley S. Kleinman, Daniel J. Butler, Conor Loy, Omary Mzava, and Jeremy Hirschberg, which also led the creation of the Cornell Aerospace Medicine Biobank (CAMBank).
Fifth, the superb @NASAGeneLab teams, @CostesSylvain, @RyanTScott, Sam Gebre, Egle Cekanaviciute, Lauren Sanders, and others for enabling controlled and long-term data access, ensuring these data as a resource for the field for the decades of spaceflight ahead.
Finally, thanks to the vision of @elonmusk and Jared Issacman to enable such ambitious studies, including the upcoming @PolarisProgram missions with Jared, @KiddPoteet, @annawmenon, @Gillis_SarahE. Also, we have the upcoming @framonauts mission led by @satofishi which will greatly expand upon this work and launch humanity into The Second Space Age.
