Vera Rubin didn't just watch history unfold; she made it—pioneering our understanding of the universe while shattering barriers for women in science. “Vera would stand up against injustice and prejudice whenever she could,” recalls Alycia Weinberger, a staff astronomer at Carnegie Science who worked alongside Rubin. “She was aggravated by how few women had won prizes from the American Astronomical Association and been elected to the National Academies. Every season, she would be busy in her office nominating women herself and exhorting others to do so.” Learn More About Rubin's Work and Advocacy for #WomenInSTEM: https://lnkd.in/gdwpKc8x

🌌Carnegie Science astronomers have revolutionized our ideas about the universe. Their success was underpinned by access to our suite of custom-designed and -built telescopes—first at Mount Wilson Observatory in the San Gabriel Mountains and eventually at our Las Campanas Observatory in the foothills of the Chilean Andes. ⛰️ Together, Carnegie Science machinists, engineers, and astronomers are building state-of-the-art instruments that will extend the lives of older telescopes and expand the potential of new and under-construction telescopes.

The world’s freshwater lakes are freezing over for shorter periods of time due to climate change. This shift has major implications for human safety, as well as water quality, biodiversity, and global nutrient cycles, according to a new review from an international team of researchers led by Carnegie Science’s Stephanie Hampton. Undertaken by scientists based in the United States, Canada, and Sweden, this analysis represents a major call-to-action for wintertime freshwater ecology research. It is published in Science Magazine.

Arthur Grossman is Carnegie Science's newest member of the National Academy of Sciences. We sat down with him to discuss his wide-ranging research program and the philosophy that's resulted in decades of groundbreaking plant science. LEARN MORE: https://lnkd.in/gPSKHEar

Congratulations to Biosphere Science and Engineering postdoc Amanda Shelton on being selected as one of PacBio's 2024 Microbial Genomics SMRT Grant Awardees! 🎉 🦠 The winners were selected from around the world for their innovative ideas. They will receive sree HiFi metagenome sequencing of six DNA samples. Shelton, who studies hot spring microbial communities in Yellowstone National Park, will use these opportunities to enhance the team’s knowledge about these fascinating, dynamic ecosystems. In her own words: “The hot spring phototrophic mat biofilms of Yellowstone National Park harbor diverse communities of bacteria performing photosynthesis at the edge. Previous research in our lab and others have identified the major species of bacteria in the community. These also revealed the high genomic diversity of Synechococcus, the major cyanobacterium in this habitat. Horizontal gene transfer, activity of mobile genetic elements within genomes, and viral attack are predicted to be drivers of microbial population diversity in this habitat and others. Our previous work using short read sequencing identified viral populations in the mat, including novel lineages, and work is ongoing to connect these viruses to the host bacteria they infect. However, our ability to do so is limited by the current data sets, as we have many viruses with no predicted host, and some hosts with fewer predicted viruses that infect them than we expected. The PacBio SMRT grant to perform high-fidelity long read sequencing and proximity ligation genomics on the mat will allow us to discover connections between bacterial host genomes and the viruses that attack them. Additionally, these data will also allow us to discover mobile genetic elements and other genomic features that can be missed by short read data. Layering the SMRT grant results on our ongoing short read sequencing work will improve our understanding of genomic diversity and connect viruses and mobile genetic elements to their host genomes in the phototrophic mat community.”

Carnegie Science geochronologist Jennifer Kasbohm is a rock and mineral detective seeking to resolve mysteries from Earth’s vast geologic history. But what can a detective do when a case has been cold for millions of years? She collects evidence from rocks around the world and brings them to her lab for investigation. Using several geochemical techniques, Kasbohm’s study of isotopes provides crucial details that may help solve these cold cases from deep in Earth’s past. Read about her latest work on a period of sustained warming 15-17 million years ago, which has implications for understanding climate change: https://lnkd.in/gm3FPB25

D.C.-area friends: Join us next week for a conversation with Moderna founder Dr. Robert Langer, who will discuss his unconventional career path and devotion to pursuing discoveries that improve medicine and inspire the next generation of innovators. FREE TICKETS: https://lnkd.in/gkdEzxPt

Carnegie Science’s Phillip Cleves is a key collaborator on a new initiative that aims to understand how climate change may impact the nervous systems and behavior of marine animals. Led by UC San Diego’s Scripps Institution of Oceanography, the Allen Discovery Center for Neurobiology in Changing Environments was launched with a $10 million grant from the Paul G. Allen Family Foundation. The new center’s researchers will work to uncover fundamental mechanisms of marine animals' nervous systems and how they have evolved to function in naturally changing environments. The team’s findings could help predict how marine organisms will respond to climate change and guide conservation efforts for vulnerable species. LEARN MORE: https://lnkd.in/gpRESv_p

We sat down with Brittany Belin, whose lab at Carnegie Science studies the biology of rhizobia, soil bacteria that can convert atmospheric nitrogen gas into plant-fertilizing ammonia. These “beneficial bacteria” form a symbiotic relationship with legumes such as peas, soybeans, and jointvetch, serving as sustainable alternatives to synthetic nitrogen fertilizers. "If we don't find ways to make agricultural production more sustainable, then in the next century, we're going to hit a point where food scarcity will become a problem—and many things will come with that. It’s not just starvation; you will have more fighting for food resources, which can mean more war," she says. 🌱 🦠 Read more: https://lnkd.in/g623hnJy
