Could ecological roles offer clues to how life began?
Producers, consumers, and decomposers play different roles in today's ecosystems. Thinking about these familiar roles led me to a question: Could their differences partly reflect the different physical and chemical environments ...
Hidden chromosome structures reveal greater complexity in how roundworms organize DNA
Almost every cell in our body contains around two meters (6.6 feet) of DNA, packed into a tiny nucleus. Yet for the cell to function, this enormous amount of genetic material must remain organized and accessible. Researchers ...

Protein fibers, a hallmark of Alzheimer's, spotted making genetic deliveries to sperm cells
Unexpectedly, a kind of protein that is usually linked with diseases in the brain may play a vital role in semen, helping shepherd genetic material into sperm cells, scientists at Columbia's Zuckerman Institute report in ...

Newly identified protein pathway helps HIV stay hidden despite treatment
Current HIV medicines are effective at suppressing the virus in the blood. However, HIV can remain "asleep" or dormant inside certain immune cells and in the brain. These hidden pockets of virus, called HIV reservoirs, are ...

Surveying the genetic battlefield to uncover the rules of rapid evolution
The Malik Lab thrives on competition. But for HHMI investigator Harmit Malik and his team at the Fred Hutchinson Cancer Center, it's the genomes—not the people—that are in conflict. The lab studies rapid evolution—the genetic ...

Scientists uncover the molecular pillars that shape our cells' powerpacks
Mitochondria are the tiny powerpacks that supply most of the energy our cells need. Their ability to generate this energy relies on a distinctive architecture: two membranes, one tucked inside the other, separated by a narrow ...

Mechanism behind PARP1-mediated DNA repair characterized, offering insight into targeted cancer therapy
When DNA is damaged, cellular processes respond and repair the DNA. Inhibiting DNA damage repair can be therapeutically beneficial in cancers with genetic vulnerabilities related to DNA damage response. Scientists at St. ...

From sea anemone to human fertility: A new research organism for understanding meiosis
Every egg cell and sperm cell depends on meiosis, a tightly choreographed process in which chromosomes find their partners, exchange genetic material and then divide. When meiosis goes awry in humans, the consequences can ...

An ancient virus in chimpanzee DNA switches off a gene that is active in humans
Humans and chimpanzees share almost all their genes. Despite this, our brains have developed in different ways. Researchers at Lund University in Sweden have now shown that a viral pandemic dating back several million years ...

DNA programs a cell-free material to build its own motors and move
Researchers have created a material that manufactures the proteins responsible for cell movement, without needing intact living cells. By embedding cell-free gene expression into a thin sheet of protein filaments, they were ...
Mapping the cell: International research team investigates the endoplasmic reticulum
Human cells contain billions of molecules. To prevent complete chaos, these molecules and the reactions between them are organized within structures known as organelles. One of the cell's most important organelles is the ...

Researchers develop AI tool to map microRNA binding sites on circular RNAs
Circular RNAs (circRNAs) are loop-shaped molecules that can influence gene regulation through interactions with microRNAs (miRNAs). This matters because circRNAs can exist as different full-length isoforms, and their back-splice ...

Mosquito bites are more complicated than they appear—getting a closer look might lead to better disease prevention
Female mosquitoes need blood to produce eggs. While much research has focused on how these hungry mosquitoes find their targets, less is known about what happens after they land on skin. Yet, a better understanding may allow ...
How does fake tan work, and why does it sometimes smell 'cookie-like'?
Real tans come from UV-triggered pigment production in living skin; that same UV exposure increases the risk of skin cancer.
