A natural chemical found in strawberries boosts memory in healthy mice

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.


Vax and Pax: taking turns to build an eye

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.


Algae provide new clues to cancer

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.


More than meets the eye

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.


Williams syndrome, the brain, and music

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.


Salk Nonresident Fellow Liz Blackburn awarded 2006 Lasker Award for Basic Medical Research

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.


Ronald M. Evans erhält den Harvey-Preis für herausragende Beiträge zur menschlichen Gesundheit

La Jolla, CA – Dr. Ronald M. Evans, Professor und Leiter des Labors für Genexpression des Salk Institute for Biological Studies wurde mit dem prestigeträchtigen Harvey-Preis für menschliche Gesundheit vom Technion-Israel Institute of Technology, Israels führender Universität für Wissenschaft und Technologie, ausgezeichnet.


Distinguishing friend from foe in the battle against cancer

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.


Two Salk researchers win McKnight Technological Innovations in Neuroscience Award

La Jolla, CA – Dr. Richard J. Krauzlis and Dr. Edward M. Callaway have been selected for the McKnight Technological Innovations in Neurosciences Award. The awards support scientists working on new and unusual approaches to understand brain function.


In a technical tour de force, Salk scientists take a global view of the epigenome

La Jolla, CA – A collaboration between researchers at the Salk Institute for Biological Studies and the University of California at Los Angeles captured the genome-wide DNA methylation pattern of the plant Arabidopsis thaliana – the “laboratory rat” of the plant world – in one big sweep.


Wenn es hart auf hart kommt, beginnen Schleimpilze mit der Synthese

La Jolla, CA – In Zeiten des Überflusses, die einzellige Schleimpilz Dictyostelium discoideum führt ein einsames Leben und knabbert an Bakterien, die den Waldboden bedecken. Aber diese einfachen Kreaturen können heroische Entwicklungsakte vollbringen: Wenn die Nahrungsversorgung mit Bakterien versiegt, Dictyostelium Amöben schließen sich mit ihren Nachbarn zusammen und bilden einen mehrzelligen Turm, der dazu dient, die Kinder zu retten.


Neuroscientists create technique to rapidly switch neurons off and on to study function

La Jolla, CA – Using molecules involved in insect molting, researchers at the Salk Institute for Biological Studies have created a laboratory method that can quickly turn off neurons in the brain and spinal cord of live animals - and can just as rapidly switch them back on.


Life and death in the hippocampus: what young neurons need to survive

La Jolla, CA – Whether newborn nerve cells in adult brains live or die depends on whether they can muscle their way into networks occupied by mature neurons. Neuroscientists at the Salk Institute for Biological Studies pin-pointed the molecular survival gear required for a young neuron to successfully jump into the fray and hook up with other cells.


Die computergestützte Analyse zeigt, dass Pflanzenhormone oft alleine agieren

La Jolla, CA – Unlike the Three Musketeers who lived by the motto “All for one, one for all,” plant hormones prefer to do their own thing. For years, debate swirled around whether pathways activated by growth-regulating plant hormones converge on a central growth regulatory module. Now, the cooperation model is challenged by researchers at the Salk Institute for Biological Studies. They show that each hormone acts largely independently in the Aug. 11 issue of Zelle.


New research points toward mechanism of age-onset toxicity of Alzheimer’s protein

La Jolla, CA – Like most neurodegenerative diseases, Alzheimer’s disease usually appears late in life, raising the question of whether it is a disastrous consequence of aging or if the toxic protein aggregates that cause the disease simply take a long time to form.


New Target for Anti-Cholesterol Drugs, Antibiotics

La Jolla, CA – A natural chemical that has been ignored by researchers largely because of the runaway success of the blockbuster statin drugs may in fact yield a rare twofer: a prime target for novel cholesterol-lowering drugs and the blueprint for a new generation of antibiotics that can take down Streptococcus pneumonia und Staphylococcus aureus.


Salk Institute researcher named Pew Scholar

La Jolla, CA – Satchidananda Panda, Ph.D., an assistant professor in the Regulatory Biology Laboratory at the Salk Institute for Biological Studies, has been named a Pew Scholar in the Biomedical Sciences. He is one of only 15 researchers in the country to receive the honor this year. The distinction comes with a $240,000 award provided over four years to support his research on the molecular basis of circadian timekeeping mechanisms in mammals.


Finding a cellular Neverland: How stem cells stay childlike

La Jolla, CA – Despite their celebrated “immortality,” the capacity of embryonic stem (ES) cells for endless division has its limits. After a very extended childhood spent dividing in a culture dish, even stem cells tend to grow up and assume adult roles as workaday nerve, muscle, or blood cells, never to return to their youthful state.


Das Zermahlen eines Schlüsselregulators der Fettsynthese hält Mäuse trotz einer fettreichen Diät schlank

La Jolla, CA – Wissenschaftler am Salk Institute for Biological Studies haben einen neuartigen Signalweg identifiziert, der die Fähigkeit des Körpers zur Speicherung oder Verbrennung von Fett reguliert. Diese Entdeckung eröffnet neue Wege zur Bekämpfung von Fettleibigkeit, Diabetes und anderen fettbedingten menschlichen Krankheiten.


New roles for growth factors: Enticing nerve cells to muscles

La Jolla, CA – During embryonic development, nerve cells hesitantly extend tentacle-like protrusions called axons that sniff their way through a labyrinth of attractive and repulsive chemical cues that guide them to their target.
