When people think of DNA, they usually think of genes, the parts that code for proteins and drive inherited traits. But there ...

Work has begun on something once-unthinkable: creating human DNA from scratch. Artificial DNA has long been an ethical ...

Whether antiretroviral therapy (ART) is always completely suppressive, or HIV might continue to replicate at low levels despite ART in some people with HIV (PWH), is still debated. Here, we ...

As the quest to extend human lifespan gains momentum, a select group of scientists is pioneering efforts to reverse the aging process. Inside state-of-the-art laboratories, researchers are ...

The ends of chromosomes, called telomeres, typically shorten as an organism ages. But when some fat-tail dwarf lemurs hibernate, they lengthen.

Roles of the sex chromosomes From there, the researchers turned their attention to genetic regulators of this process and focused on the Y chromosome. By performing gene knockdowns, they identified ...

The Y chromosome, which determines the sex of human and other mammal babies, is slowly degenerating and may disappear within a few million years, raising fears of extinction. However, a 2022 study ...

The human genetic blueprint is deceptively simple. Our genes are tightly wound into 46 X-shaped structures called chromosomes. Crafted by evolution, they carry DNA and replicate when cells divide, ...

A new quick and precise technique for producing artificial human chromosomes has been developed, which could be used to power advanced gene therapies.

Karyotyping is of importance for detecting chromosomal aberrations in human disease. However, chromosomes easily appear curved in microscopic images, which prevents cytogeneticists from analyzing ...

For many years, the human Y chromosome was terra incognita. Scientists completed the genetic sequences of other chromosomes, the threadlike structures that hold an organism’s DNA. But more than ...
