Multicancer early detection tests are among the priorities of the Biden administration’s Cancer Moonshot. The tests show promise, but questions remain about when and how to use them.
Sequencing the genome of a virus gives researchers information on how mutations can affect its transmissibility and virulence.

Genome sequencing technologies have transformed biological research in many ways, but have had a much smaller effect on the treatment of common diseases.
The concept of three-parent babies defies what we learned in health class. But how and when is the third parent involved? At what stage? Jennifer Barfield gives us an update on the birds and the bees.
Sunrise at noon in the Arctic. Little exposure to sun was a piece of the genetic puzzle.

Why was one gene mutation that affects hair, teeth, sweat glands and breasts ubiquitous among ice age Arctic people? New research points to the advantage it provided for ancestors of Native Americans.
A core idea in molecular biology is that one gene codes for one protein. Now biologists have found an example of a gene that yields two forms of a protein – enabling it to evolve new functionality.
As genes are favored or phased out, human evolution continues.

Comparing genomes of more than 200,000 people, researchers identified genetic variants that are less common in older people, suggesting natural selection continues to weed out disadvantageous traits.
Releasing just 100 mice carrying a faulty gene designed to stop them reproducing can remove an entire population of 50,000, a new study shows, paving the way for new eradication efforts.

Two US researchers have traced the majority of cancers to DNA replication errors during our natural cell replacement. Their finding asks for a renewed inquiry into the role of “chance” in cancer.
What can a single person’s flu infection tell you about how the virus changes around the world?

A new research paper reports dangerous side effects in CRISPR-edited mice. Some scientists are pushing back, placing blame for the unwanted mutations on the experiment, not the technique.
Our cells have a built-in genetic clock, tracking time… but how accurately?

How do scientists figure out when evolutionary events – like species splitting away from a common ancestor – happened? It turns out our DNA is a kind of molecular clock, keeping time via genetic changes.
Scientists found that malaria parasites resistant to antimalarial Atovaquone cannot survive inside their mosquito host.

Evolution also does not claim humans evolved from primates. Neither does it say non-human primates, including monkeys, baboons, chimpanzees and gorillas, will evolve into humans with time.
You’d be in bad shape if your cells couldn’t fix DNA issues that arise.

Cells must repair the thousands of bits of DNA damage they incur every day. These cellular mechanisms fend off cancerous tumors, and cancer researchers are working to harness their power.
