Some rare people may purge most HIV from their bodies, leaving only broken copies of the virus or copies locked in molecular prisons, from which there is no escape.

It’s not unusual for geochronologist Rainer Grün to bring human bones back with him when he returns home to Australia from excursions in Europe or Asia. Jawbones from extinct hominins in Indonesia, Neanderthal teeth from Israel, and ancient human finger bones unearthed in Saudi Arabia have all at one point spent time in his lab at Australian National University before being returned home.

Modern genomes from Nigeria and Sierra Leone show signals that scientists call "ghost" DNA — from an unknown human ancestor. That means that prehistoric humans likely procreated with an unknown group.

For decades, scientists have been intrigued by tiny viruses whose genetic material can be read both forward and backward. New research begins to explain this puzzling property.

Everybody wants to live as long as possible. We try our best to take care of ourselves — we watch our diet, we stay active, and we throw away the cigarettes. Owing to our gallant efforts, and thanks to advances in science and medicine, human life expectancy across the world doubled in the 20th century. The average human can now expect to live past 70 years old.

DNA is the repository for genetic information. We’ve been tinkering with it since the 1970s, trying to alter the characteristics of organisms in a single generation, like boosting crop resistance to insect pests or even making pigs glow. Only recently have researchers popularized DNA as something else: a construction material. Earlier this year, researchers assembled an intelligent and autonomous nanostructure entirely out of DNA that delivered and released a cancer drug.

One of the more startling discoveries arising from genomic sequencing of ancient hominin DNA is the realisation that all humans outside Africa have traces of DNA in their genomes that do not belong to our own species.

What would the implications be if decoding your genes cost less than a pair of designer jeans? We might soon find out after a Chinese company claimed it can sequence the human genome for $100. The speed at which the price of genetic sequencing has fallen has been astonishing, from $50,000 a decade ago to roughly $600 today. For a long time, the industry saw the $1,000 genome as the inflection point at which we would enter the genomic age—where getting a read out of your DNA would be within reach for huge swathes of the population.

In a paddock in rural Australia are five calves that look just like any others. But they're not — they're biological hazards.

Emotional, social and psychiatric problems in children and adolescents have been linked to higher levels of genetic vulnerability for adult depression. University of Queensland scientists made the finding while analysing the genetic data of more than 42,000 children and adolescents from seven cohorts across Finland, the Netherlands, Norway, Sweden and UK.

In Human Errors, Lents “demonstrated that the human body can’t possibly be considered the product of an intelligent designer. Rather, its flaws tell the story of evolution,” reviewer Harriet Hall asserts in a Skeptical Inquirer magazine review of the nonfiction book (“Evolution’s Flaws Are in Us”).

According to the latest material published by researchers at the University of Copenhagen, it was finally possible to take genetic information from a human grave that has an age of about 800,000 years. This important step towards the future of past genetic discoveries was made in collaboration with the National Center for Research on Human Evolution (CENIEH) from Burgos and many other institutions.

Some people die from covid-19, and others who are infected don’t even show symptoms. But scientists still don’t know why. Now consumer genomics company 23andMe is going to offer free genetic tests to 10,000 people who’ve been hospitalized with the disease, hoping to turn up genetic factors that could point to an answer.

Researchers have created an embryo containing both human and mouse cells in a major advancement of genetically modified organisms. The hybrid embryo, referred to as a human-animal chimera, was grown by a team at the State University of New York at Buffalo and the Roswell Park Comprehensive Cancer Center.

Emma Wren Gibson, frozen as an embryo in 1992, was born a few days after Thanksgiving in 2017, more than 25 years later. It’s the longest an embryo is known to have been frozen before being born as baby. In fact, the embryo that became Emma is only a year younger than the woman who gave birth to her, Tina Gibson. “This embryo and I could have been best friends,” Gibson, now 26, told CNN. Tina and her husband “adopted” the frozen embryo after learning he was likely infertile.

The CRISPR-Cas9 gene editing system is an extremely powerful tool, but there are still a few kinks to iron out. One of the main problems is off-target edits, which can have serious consequences. Now, researchers have found a particular mutation of the CRISPR enzyme that’s almost 100 times more precise than the most commonly used one.

Gedmatch, the DNA analysis site that police used to catch the so-called Golden State Killer, was pulled briefly offline on Sunday while its parent company investigated how its users’ DNA profile data apparently became available to law enforcement searches.

Pain is mediated through specialized nerve cells that are activated when potentially harmful things affect various parts of our bodies. These nerve cells have a special ion channel that has a key role in starting the electrical impulse that signals pain and is sent to the brain. According to a new study by researchers at the Max Planck Institute for Evolutionary Anthropology in Germany and the Karolinska Institutet in Sweden people who inherited the Neandertal variant of this ion channel experience more pain.

A massive study finds that regional differences in how slaves were treated throughout the Americas are reflected in the DNA of present-day Americans of African descent.

A new protein opens doors for gene editing by gaining access to hard-to-reach areas of the genome.
