Molecule that spurs cell’s recycling center may help Alzheimer’s patients
Cells, which employ a process called autophagy to clean up and reuse protein debris leftover from biological processes, were the original recyclers. A team of scientists from Paul Greengard’s Rockefeller University laboratory have linked a molecule that stimulates autophagy with the reduction of ...
New genetic technique probes the cause of skin cell differentiation in mammals
A tremendous amount of genetics research has been done in flies and tiny worms, in part because scientists have good tools for tweaking these creatures’ DNA. Now, by adapting a powerful method of RNA interference for use in mice, researchers have identified key pathways that cause skin cells to d...
‘Round-the-clock’ lifestyle could disrupt metabolism, brain and behavior
In Civilization and Its Discontents, Sigmund Freud argued that modern society was hard on human psychology, forcing people to get along in unnaturally close quarters. Now newly published research from ÐÓ°É points out a different discontent in the developed world, namely, the...
Newly discovered deep sea lobster named for Rockefeller’s Jesse Ausubel
Some scientists receive prizes for their contributions to science, others find themselves on postage stamps. Rockefeller University’s Jesse Ausubel name is now immortalized in the scientific name of a newly discovered, rare new genus of deep water lobster. Ausubel was given this honor as a tribut...
New research traces evolutionary path of multidrug resistant strep bacteria
Despite penicillin and the dozens of antibiotics that followed it, streptococcus bacteria have remained a major threat to health throughout the world. The reason: the superb evolutionary skills of this pathogen to rapidly alter its genetic makeup. In a landmark paper published this week in Scienc...
Research shows when stem cell descendants lose their versatility
Stem cells are the incomparably versatile progenitors of every cell in our body. Some maintain this remarkable plasticity throughout the life of an animal, prepared to respond as needed to repairÌýan injury, for instance. Others differentiate into specialized cells, regenerating tissue or facilita...
Scientists identify protein that drives survival of gastrointestinal tumors
Scientists identify protein that drives survival of gastrointestinal tumors For patients with gastrointestinal stromal tumors, or GISTs, the blockbuster cancer drug Gleevec has been a reason to hope. Since the drug’s introduction, survival rates have climbed dramatically and recurrence has fal...
Studies describe key role for a protein in cell division
Just before a cell divides into two — the basic act of reproducing life — the cellular environment must be exquisitely prepared. The exact timing and localization of the vast array of molecules and processes involved in duplicating chromosomes and separating the offspring from the parent is one ...
Therapy for fearsome brain disease could target blood
The aggregated proteins strewn about a deranged brain are the hallmark of one of the most feared and common neurodegenerative disorders on the planet: Alzheimer’s disease. But while these irregular, gunky proteins, called amyloid-β, are believed to contribute to the deterioration of memory and co...
Paleovirology expanded: New virus fragments found in animal genomes
Understanding the evolution of a virus can help beat it. This is immediately true in the fight against the ever-changing influenza bug, and potentially so in ongoing battles against Ebola and dengue fever, too. New research now points the way to a fossil record of viruses that have surprisingly i...
