Study reveals the structure of a protein crucial for DNA replication
Our DNA contains instructions crucial for virtually all forms of life on this planet. But for life to propagate, this blueprint must be copied and passed on to future generations. New findings describing the structure of a key molecule involved in DNA replication place another piece in the puzzle...
Researchers explore how protein production gets distorted in skin cancer
Each cell in the body follows a strict protocol for manufacturing the proteins it needs to function. When a cell turns cancerous, however, its protein production goes off script. A new study led by researchers at the Rockefeller University takes a close look at one way in which this procedure goe...
Antibody combination puts HIV on the ropes
Without antiretroviral drug treatment, the majority of people infected with HIV ultimately develop AIDS, as the virus changes and evolves beyond the body’s ability to control it. But a small group of infected individuals—called elite controllers—possess immune systems capable of defeating the ...

New research clarifies why wounds heal more slowly with age
Older bodies need longer to mend. This reality of aging has been documented since World War I, with the observation that wounds heal slower in older soldiers. Yet until now, researchers have not been able to tease out what age-related changes hinder the body’s ability to repair itself. Recent e...
Researchers shed new light on RNA’s journey out of a cell’s nucleus
Cells secure DNA within their nuclei like a secret code stashed in a vault. However, the tightly controlled borders of the nucleus create a challenge: In order for the cell to produce essential proteins, messages derived from DNA must somehow escape the nucleus in the form of RNA molecules. New w...
A possible explanation for why male mice tolerate stress better than females

A common brain cell shapes the nervous system in unexpected ways
More than half of our brains are made up of glial cells, which wrap around nerve fibers and insulate them—similarly to how the plastic casing of an electric cable insulates the copper wire within—allowing electrical and chemical impulses to travel faster. In the past, neuroscientists considered ...
A newly discovered way for cells to die
Some cells are meant to live, and some are meant to die. The linker cell of Caenorhabditis elegans, a tiny worm that is a favored model organism for biologists, is among those destined for termination. This cell helps determine the shape of the gonad in male worms—and then it dies, after two days...
Parasites reveal how evolution has molded an ancient nuclear structure

Researchers discover new aspect of gene regulation and a possible target for cancer drugs
There are about 20,000 genes in the human genome, but not all are used in all cells at all times. At any given moment, a cell is converting only roughly half its genes into proteins. And of those active genes, about 75 percent are regulated by a process known as “RNA polymerase pausing.” This...
Study suggests new way to help the immune system fight off sleeping sickness parasite
Some infectious diseases are particularly difficult to treat because of their ability to evade the immune system. One such illness, African sleeping sickness, is caused by the parasite Trypanosoma brucei, transmitted by the tsetse fly, and is fatal if left untreated. The trypanosome parasite is t...
New research helps to explain how temperature shifts the circadian clock
For many living things, a roughly 24-hour internal clock governs the rhythms of life—everything from sleep in animals, to leaf opening in plants and reproduction in bread mold. Scientists have come to understand much about this internal time-keeping system, but one important aspect, its complex r...
Study reveals new mechanism in nicotine addiction
Part of the reason people find smoking difficult to quit is that each time they have a cigarette, feelings of craving, irritability and anxiety melt away. This component of addiction is known as negative reward and is controlled in part by a region of the brain called the habenula. The neurotrans...
DNA strands often “wiggle” as part of genetic repair
Sometimes, the molecules that make up life exhibit strange behavior. For instance, in simple organisms such as yeast, when genetic material becomes damaged, the affected DNA strands increase their motion, waving about inside the cell like a sail unfurled. Over the years, scientists have seen more...
