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.
Resistance to a commonly used antimalarial medication, Atovaquone, can’t spread to the general human population, a new research found.
Understanding how evolution affects behaviour can help address societal problems.
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.
Genetic therapy might be able to reverse the harmful effects of sickle cell anaemia.
Gene therapy is allowing us to switch on natural beneficial mutations to counteract the effects of negative mutations in diseases such as sickle cell anaemia.
The genetic modification of humans make many people feel very uncomfortable.
The first case of genetically engineering a human embryo to cure a congenital disease is a technical breakthrough but raises troubling ethical questions.
Won’t get fooled again (posed by models).

DNA profiling is a powerful tool, but being faced with identical DNA from identical genes has been a problem - until now.
British researchers have developed a new way of tracing the life history of individual cells back to their origins in the…
