In Alzheimer’s disease, the problem is amyloid-β, a protein that accumulates in the brain and causes nerve cells to weaken and die. Drugs designed to eliminate plaques made of amyloid-β have a fatal problem: they need to enter the brain and remove the plaques without attacking healthy brain cell...

Reproduce or perish. That’s the bottom line for genes. Because nothing lives forever, reproduction is how life sustains itself, and it happens most fundamentally in the division and replication of the cell, known as mitosis. Now new research at Rockefeller University has detailed a key role in mi...

MicroRNAs, already linked to cancer, heart disease and mental disorders such as schizophrenia, may also be involved in addiction. A team of Rockefeller University neuroscientists has shown that a protein that plays a crucial role in the regulation of microRNAs, short stretches of RNA that silenc...

Long before a baby can flash her first smile, sprout a first tooth or speak a first word, the neurons that will form her central nervous system must take their first, crucial steps. And these steps must be careful to take the right neurons to the right places and avert developmental disasters th...

Skeletal muscle enables us to walk, run or play a musical instrument, but it also plays a crucial role in controlling disease. Rockefeller University scientists have now shown how a specific molecule in skeletal muscle regulates energy expenditure, a finding that may lead to new treatments for c...

After more than a century of technological refinements, zippers still get stuck. So do the molecular machines that routinely unzip the double helix of DNA in our cells after billions of years of evolution, and the results can be lethal. In research to be published July 30 in Molecular Cell and a...

In the battle between insect predators and their prey, chemical signals called kairomones serve as an early-warning system. Pervasively emitted by the predators, the compounds are detected by their prey, and can even trigger adaptations, such a change in body size or armor, that help protect the...

When HIV was first discovered to cause AIDS in 1981, prominent scientists expected to have an effective vaccine within a couple of years. Three decades later, the disease has killed more than 25 million people and defied every effort so far to inoculate against it. But researchers at Rockefeller ...

Neuroscientists once thought that the brain’s wiring was fixed early in life, during a critical period beyond which changes were impossible. Recent discoveries have challenged that view, and now, research by scientists at Rockefeller University suggests that circuits in the adult brain are con...

Alzheimer’s disease has long been studied primarily as a disease of neurons. But researchers have now shown how the disease may be damaging the brain by choking off blood flow. In experiments published June 10 in Neuron, scientists at Rockefeller University reveal that amyloid-β, which builds up ...
