In memory of the exemplary scientist David Baltimore, who passed on September 6th, TWiV has re-issued its 100th episode featuring a discussion with him on viruses. Our lab was incredibly fortunate to work with and learn from him since he joined @caltech.edu almost 28 years ago. tinyurl.com/2md4kknj

Mourning the loss of David Baltimore, a Nobel laureate and President Emeritus of Caltech. His groundbreaking work on reverse transcriptase reshaped our understanding of genetics and paved the way for advances in cancer and HIV research. A true giant in science. www.caltech.edu/about/news/c...

Science saves countless lives. But proposed cuts to NIH & NSF threaten to shut down labs & stall progress millions of families are counting on. Urge Congress to protect and restore funding for medical research. Act now: tinyurl.com/24p2n4fc #ScienceSaves #FundNIH

Exciting news! A few weeks ago, the TWiV podcast reviewed a paper from Michael Letko's lab (@fviromics.bsky.social) featuring one of our graduate students as a co-first author. Give it a listen! www.microbe.tv/twiv/twiv-12...

An unvaccinated child died during a measles outbreak in rural West Texas, marking it the first U.S. death from the highly contagious respiratory disease since 2015. Vaccines against the disease are safe & effective, and measles was once considered eliminated. @apnews.com apnews.com/article/meas...

Congratulation to @jacobparresau.bsky.social and @elowitzlab.bsky.social for their new publication in @cellpress.bsky.social on competitive protein dimerization networks! www.cell.com/cell/fulltex...

from @nature.com "almost all grant-review meetings remain suspended at the US National Institutes of Health (NIH), preventing the world’s largest public funder of biomedical research from spending much of its US$47 billion annual budget." go.nature.com/4k8Njjx

@caltech.edu asked Dr. Pamela Bjorkman "if overusing antibiotics can be harmful. Should we worry about overusing vaccines too?" The short answer is no. Swipe to learn more from Caltech's Pamela Bjorkman. #AskCaltech at caltech.edu/AskCaltech. 1/2

Update on Campus Operations: Caltech’s campus will remain closed on Thursday, January 9. The Institute intends to resume operations on Friday, January 10, pending continued assessments of the situation. Individuals who do come to campus for essential positions are advised to wear a K/N95 mask.

Please join us in welcoming our newest Professor of Chemistry, Sandeep Sharma! 👋 His group's research efforts are directed towards developing algorithms that solve the problem of electronic structure theory. He loves to spend time with his family and enjoys playing racket sports. Welcome, Sandeep!

After more than 4 years, the infamous and dangerous hydroxychloroquine paper has finally been officially retracted! 🎉 Many criticized this unfounded publication, but a huge thank you to @elisabethbik.bsky.social for leading the charge! #Immunology #Virology #Science #COVID19

A bit old but here is a great visual representation from @science.org of the fact that vaccines do work and help keep infectious diseases at bay. www.science.org/content/arti...
