LA JOLLA–When it comes to developing efficient, robust networks, the brain may often know best.
Researchers from the Salk Institute for Biological Studies and Carnegie Mellon University have, for the first time, determined the rate at which the developing brain eliminates unneeded connections between neurons during early childhood.
LA JOLLA–Healthy brain, muscle, eye and heart cells would improve the lives of tens of thousands of people around the world with debilitating mitochondrial diseases. Now, researchers at the Salk Institute have gotten one step closer to making such cures a reality: they’ve turned cells from patients into healthy, mutation-free stem cells that can then become any cell type. The new approach is described July 15, 2015 in Nature.
LA JOLLA–The Salk Institute today announced that Rusty Gage, Salk professor in the Laboratory of Genetics, has been selected as one of five recipients of the Paul G. Allen Family Foundation’s Allen Distinguished Investigator (ADI) program and will be awarded $1.5 million to conduct his research. These researchers have projects aimed at uncovering the elusive biological foundations of Alzheimer’s disease. The projects are funded at a total of $7 million over three years.
LA JOLLA—Salk Institute plant biologist Julie Law has been named a Rita Allen Foundation Scholar, a distinction given to biomedical scientists whose research holds exceptional promise for advancing the frontiers of knowledge about how biological systems function in health and disease.
LA JOLLA–Unveiling how the 20,000 or so proteins in the human body work–and malfunction–is the key to understanding much of health and disease. Now, Salk researchers developed a new technique that allows scientists to better understand an elusive step critical in protein formation.
LA JOLLA–Mice that have a genetic version of mitochondrial disease can easily be mistaken for much older animals by the time they are nine months old: they have thinning grey hair, osteoporosis, poor hearing, infertility, heart problems and have lost weight. Despite having this disease at birth, these mice have a “secret weapon” in their youth that staves off signs of aging for a time.
LA JOLLA–As a tumor grows, its cancerous cells ramp up an energy-harvesting process to support its hasty development. This process, called autophagy, is normally used by a cell to recycle damaged organelles and proteins, but is also co-opted by cancer cells to meet their increased energy and metabolic demands.
LA JOLLA–Telomeres, specialized ends of our chromosomes that dictate how long cells can continue to duplicate themselves, have long been studied for their links to the aging process and cancer. Now, a discovery at the Salk Institute shows that telomeres may be more central than previously thought to a self-destruct program in cells that prevents tumors, a function that could potentially be exploited to improve cancer therapies.
LA JOLLA–What if you found out that pieces of your front door were occasionally flying off the door frame to carry out chores around the house? That’s the kind of surprise scientists at the Salk Institute experienced with their recent discovery that nucleoporins–proteins that act as cellular “doorways” to help manage what goes in and out of a cell’s nucleus–are actually much bigger players in expressing genes than previously thought.
LA JOLLA–The Pew Charitable Trusts announced today that Salk Institute scientist Nicola Allen, an assistant professor in the Molecular Neurobiology Laboratory, is one of 22 researchers to be named a Pew Scholar in the Biomedical Sciences. Allen joins the ranks of more than 600 outstanding scientists who have been selected as Pew scholars in the 30 years since the program’s inception.
LA JOLLA, CA–The Salk Institute is pleased to announce the election of neuroscientist Thomas M. Jessell and business leader Daniel Tierney to its Board of Trustees. The Board voted on the appointments in April.
LA JOLLA–Bread, cereal and other sugary processed foods cause rapid spikes and subsequent crashes in blood sugar. In contrast, diets made up of vegetables, fruits and whole grains are healthier, in part because they take longer to digest and keep us more even-keeled.
LA JOLLA–For more than a decade, scientists have had a working map of the human genome, a complete picture of the DNA sequence that encodes human life. But new pages are still being added to that atlas: maps of chemical markers called methyl groups that stud strands of DNA and influence which genes are repressed and when.
LA JOLLA–Expanding on its leadership in genetics, the Salk Institute is pleased to announce the appointment of Graham McVicker as an assistant professor in the Center for Integrative Biology and in the Laboratory of Genetics.
LA JOLLA–Scientists at the Salk Institute have discovered that the role of neurons–which are responsible for specific tasks in the brain–is much more flexible than previously believed.
Salk scientist Joanne Chory, a professor in the Plant Molecular and Cellular Biology Laboratory, has received the prestigious honor of being elected to the American Philosophical Society (APS). The APS is an eminent scholarly organization of international reputation, which promotes useful knowledge in the sciences and humanities. This country’s first learned society, the APS has played an important role in American cultural and intellectual life for over 250 years.
LA JOLLA–Scientists at the Salk Institute have discovered a novel type of pluripotent stem cell–cells capable of developing into any type of tissue–whose identity is tied to their location in a developing embryo. This contrasts with stem cells traditionally used in scientific study, which are characterized by their time-related stage of development.
LA JOLLA–Stem cells, which have the potential to turn into any kind of cell, offer the tantalizing possibility of generating new tissues for organ replacements, stroke victims and patients of many other diseases. Now, scientists at the Salk Institute have uncovered details about stem cell growth that could help improve regenerative therapies.
LA JOLLA–A study tying the aging process to the deterioration of tightly packaged bundles of cellular DNA could lead to methods of preventing and treating age-related diseases such as cancer, diabetes and Alzheimer’s disease, as detailed April 30, 2015, in Science.
LA JOLLA—The National Academy of Sciences (NAS) recently announced that Salk Institute Professor Vicki Lundblad is one of 84 new members to be elected to the NAS. The election is considered one of the highest honors accorded a U.S. scientist. Lundblad’s recognition brings the number of Salk faculty elected to the NAS to 14.
Your partnership allows our scientists to accelerate the pace of high-risk, high-reward discoveries that have the potential to benefit the health of all humanity-be it cancer, Alzheimer’s disease, climate change, infectious diseases or more.
