Washington, DC—California Governor Gavin Newsom on Monday announced $20 million in his 2023 fiscal year budget to support Carnegie’s new research facility in Pasadena. The proposed budget allocation still must clear the California State Senate and Assembly, which will begin to hold hearings in the coming weeks. It must be adopted by June 15. 

The new 135,000-square-foot, state-of-the-art campus will bring the institution’s life and environmental scientists together in a single location adjacent to Caltech—making a decisive investment in the global fight against climate change. The facility will house more than 200 new hires and relocated staff, who

Washington, DC—Pioneering microbiome specialist Margaret McFall-Ngai has been named the inaugural director of Carnegie’s newly launched research division focused on life and environmental sciences, which will deploy an integrated, molecular-to-global approach to tackling the challenges of sustainability, resilience, and adaptation to a changing climate. McFall-Ngai will join the institution in January, 2022, from the University of Hawai‘i at Mānoa, where she is a professor at the Pacific Biosciences Research Center’s Kewalo Marine Laboratory and the center’s director emerita.

Baltimore, MD—Carnegie’s Steven Farber was awarded nearly $500,000 over three years by The G. Harold & Leila Y. Mathers Foundation to identify the chemical components of cinnamon oil that show effectiveness against cardiovascular disease-causing fats.

Fat molecules, or lipids, such as cholesterol and triglycerides are shuttled around the circulatory system by a protein called Apolipoprotein-B, together forming complexes of lipid and protein that are called lipoproteins but may be more commonly known as “bad cholesterol.” It can get embedded in the sides of blood vessels and harden, forming a dangerous buildup that makes it more difficult for the heart

The Gall laboratory studies all aspects of the cell nucleus, particularly the structure of chromosomes, the transcription and processing of RNA, and the role of bodies inside the cell nucleus, especially the Cajal body (CB) and the histone locus body (HLB).

Much of the work makes use of the giant oocyte of amphibians and the equally giant nucleus or germinal vesicle (GV) found in it. He is particularly  interested in how the structure of the nucleus is related to the synthesis and processing of RNA—specifically, what changes occur in the chromosomes and other nuclear components when RNA is synthesized, processed, and transported to the cytoplasm.

The Fan laboratory studies the molecular mechanisms that govern mammalian development, using the mouse as a model. They use a combination of biochemical, molecular and genetic approaches to identify and characterize signaling molecules and pathways that control the development and maintenance of the musculoskeletal and hypothalamic systems.

The musculoskeletal system provides the mechanical support for our posture and movement. How it arises during embryogenesis pertains to the basic problem of embryonic induction. How the components of this system are repaired after injury and maintained throughout life is of biological and clinical significance. They study how this system is

Approximately half of the gene sequences of human and mouse genomes comes from so-called mobile elements—genes that jump around the genome. Much of this DNA is no longer capable of moving, but is likely “auditioning”  perhaps as a regulator of gene function or in homologous recombination, which is a type of genetic recombination where the basic structural units of DNA,  nucleotide sequences, are exchanged between two DNA molecules to  repair  breaks in the DNA  strands. Modern mammalian genomes also contain numerous intact movable elements, such as retrotransposon LINE-1, that use RNA intermediates to spread about the genome.

In mammals, most lipids, such as fatty acids and cholesterol, are absorbed into the body via the small intestine. The complexity of the cells and fluids that inhabit this organ make it very difficult to study in a laboratory setting. The goal of the Farber lab is to better understand the cell and molecular biology of lipids within digestive organs by exploiting the many unique attributes of the clear zebrafish larva  to visualize lipid uptake and processing in real time.  Given their utmost necessity for proper cellular function, it is not surprising that defects in lipid metabolism underlie a number of human diseases, including obesity, diabetes, and atherosclerosis.

The Donald Brown laboratory uses  amphibian metamorphosis to study complex developmental programs such as the development of vertebrate organs. The thyroid gland secretes thyroxine (TH), a hormone essential for the growth and development of all vertebrates including humans. To understand TH, director emeritus Donald Brown studies one of the most dramatic roles of the hormone, the control of amphibian metamorphosis—the process by which a tadpole turns into a frog. He studies the frog Xenopus laevis from South Africa.

 Events as different as the formation of limbs, the remodeling of organs, and the resorption of tadpole tissues such as the tail are all directed by TH

The first step in gene expression is the formation of an RNA copy of its DNA. This step, called transcription, takes place in the cell nucleus. Transcription requires an enzyme called RNA polymerase to catalyze the synthesis of the RNA from the DNA template. This, in addition to other processing factors, is needed before messenger RNA (mRNA) can be exported to the cytoplasm, the area surrounding the nucleus.

Although the biochemical details of transcription and RNA processing are known, relatively little is understood about their cellular organization. Joseph G. Gall has been an intellectual leader and has made seminal breakthroughs in our understanding of chromosomes, nuclei and

Phillip Cleves’ Ph.D. research was on determining the genetic changes that drive morphological evolution. He used the emerging model organism, the stickleback fish, to map genetic changes that control skeletal evolution. Using new genetic mapping and reverse genetic tools developed during his Ph.D., Cleves identified regulatory changes in a protein called bone morphogenetic protein 6 that were responsible for an evolved increase in tooth number in stickleback. This work illustrated how molecular changes can generate morphological novelty in vertebrates.

Cleves returned to his passion for coral research in his postdoctoral work in John Pringles’ lab at Stanford
