La Jolla, CA – Wielding a palette of chromosome paints, scientists at the Salk Institute for Biological Studies have taken a step closer to understanding the relationship between aging and cancer by visualizing chromosomes of cells from patients with a heritable premature aging disease known as Werner Syndrome.
La Jolla, CA – Nobody questions that the color of our eyes is encoded in our genes. When it comes to behavior the concept of “DNA as fate” quickly breaks down – it’s been long accepted that both genes and the environment shape human behavior. But just how much sway the environment holds over our genetic destiny has been difficult to untangle.
La Jolla, CA – The National Academy of Sciences has selected Joseph R. Ecker, professor in the Plant Biology Laboratory and director of the Salk Institute Genomic Analysis Laboratory, to receive the 2007 John J. Carty Award for the Advancement of Science “for contributions in the areas of ethylene signal transduction and Arabidopsis genomics that have paved the way for a revolution in modern agriculture.”
La Jolla, CA – A few glimpses are enough to perceive a seamless and richly detailed visual world. But instead of "photographic snapshots," information about the color, shape and motion of an object is pulled apart and sent through individual nerve cells, or neurons, to the visual center in the brain. How the brain puts the scene back to together has been hotly debated ever since neurons were discovered over a century ago.
La Jolla, CA – Researchers at the Salk Institute for Biological Studies in collaboration with scientists at the University of California, San Diego (UCSD) took a high resolution “action shot” of a protein switch that plays a crucial role in the development of the nervous system. Their findings, published in the Dec. 8 issue of the journal Molecular Cell, provide a template for the design of small molecule inhibitors to control that switch, a protein called Scp1, at will.
La Jolla, CA —Dr. Andrew Dillin, an assistant professor in the Molecular and Cellular Biology Laboratory at the Salk Institute for Biological Studies, has been selected for the 2007 McKnight Neuroscience of Brain Disorders Award. He will receive $300,000 over a three-year period to study “age-associated neuroprotection by insulin/IGF-1 signaling.”
La Jolla, CA – Professors Terrence J. Sejnowski and Inder Verma have been awarded the distinction of AAAS Fellow. Election as a Fellow of the American Association for the Advancement of Science is an honor bestowed upon members by their peers.
La Jolla, CA – Chop off a salamander’s leg and a brand new one will sprout in no time. But most animals have lost the ability to replace missing limbs. Now, a research team at the Salk Institute for Biological Studies has been able to regenerate a wing in a chick embryo – a species not known to be able to regrow limbs – suggesting that the potential for such regeneration exists innately in all vertebrates, including humans.
La Jolla, CA – When you dial 911 you expect rescuers to pull up at your front door, unload and get busy – not park the truck down the street and eat donuts.
La Jolla, CA – The Salk Institute for Biological Studies today announced that Dr. Richard Murphy will retire from his position of President and CEO on July 1, 2007. Murphy, 62, has served in this capacity since Oct. 1, 2000. Murphy made his announcement at the Nov. 10 meeting of the Salk Institute’s Board of Trustees.
La Jolla, CA – Having your heart in the right place usually means having it located on the left side of your body. But just how a perfectly symmetrical embryo settles on what’s right and what’s left has fascinated developmental biologists for a long time. The turning point came when the rotational beating of cilia, hair-like structures found on most cells, was identified as essential to the process.
La Jolla, CA – Targeted tumor therapy lobs toxic payloads directly into tumors to destroy cancer cells while leaving normal cells unharmed. In the case of radiotherapy, these missiles, which should unerringly home in on the target and make it implode, consist of radioactive bullets guided by small molecules – known as agonists – that recognize and then activate specific receptors over-expressed on the surface of tumor cells.
La Jolla, CA – Mothers have long exhorted their children to eat their fruit and vegetables. But once kids are beyond mom’s watchful eye, the hated greens often go the way of Barbie dolls and power rangers. Now, there’s another reason to reach for colorful fruits past adolescence.
La Jolla, CA – Opposing ball clubs don’t take the field at the same time, and neither do teams of proteins responsible for creating the eye. While one team builds the retina, in adjacent cellular turf the opponents are busy constructing the cord that carries visual signals to the brain. And these guys aren’t supposed to mingle.
La Jolla, CA – A microscopic green alga helped scientists at the Salk Institute for Biological Studies identify a novel function for the retinoblastoma protein (RB), which is known for its role as a tumor suppressor in mammalian cells. By coupling cell size with cell division, RB ensures that cells stay within an optimal size range.
La Jolla, CA – Ever watch a jittery video made with a hand-held camera that made you almost ill? With our eyes constantly darting back and forth and our body hardly ever holding still, that is exactly what our brain is faced with. Yet despite the shaky video stream, we usually perceive our environment as perfectly stable.
La Jolla, CA – Children with Williams syndrome, a rare genetic disorder, just love music and will spend hours listening to or making music. Despite averaging an IQ score of 60, many possess a great memory for songs, an uncanny sense of rhythm, and the kind of auditory acuity that can discern differences between different vacuum cleaner brands.
La Jolla, CA – Elizabeth H. Blackburn, Ph.D., has been awarded the highly prestigious Albert Lasker Basic Medical Research Award for her pioneering work on telomeres, the structures that protect chromosome ends, the Albert and Mary Lasker Foundation announced on Saturday.
La Jolla, CA – Dr. Ronald M. Evans, professor and head of the Gene Expression Laboratory of the Salk Institute for Biological Studies, was awarded the prestigious Harvey Prize in Human Health from the Technion-Israel Institute for Technology, Israel’s premier science and technology university.
La Jolla, CA – The latest generation of cancer chemotherapeutic drugs specifically targets mutant enzymes or “oncoproteins” that have run amok and now promote uncontrolled cell growth. As promising as these drugs are, cancer cells with their backs against the wall have the tendency to fight back. A major goal of cancer research is to frustrate these acts of cellular desperation.
