A genetically edited pig kidney has been successfully transplanted into a living patient for the first time. Reports indicate the man is doing well a few weeks on, raising hopes for a wider pool of donated organs in future.

In what may put some of us to shame, apes instantly recognize family and friends that they haven’t seen in more than two decades, which is the longest ‘social memory’ in a non-human animal ever documented.

A 2021 study caused a stir by claiming that a set of fossilized human footprints were 20,000 years old – much earlier earlier than humans were thought to have set foot in North America. Now two extra dating methods have seemingly confirmed the age.

Archaeologists have discovered the oldest evidence of artificial structures made of wood, dating back almost half a million years – predating the appearance of our own species and suggesting our relatives settled down much earlier than we thought.

Researchers have mapped where and how strongly we experience different kinds of love, covering everything from romantic love to love for strangers. The findings shed light on how context and the object of love affects our subjective feelings of it.

Ötzi the Iceman is one of the most well-studied individuals in human history, but there always seems to be more to learn about him. A new genomic study has now found that he looked very different from the way previous studies had imagined him.

Anthropologists have assembled the most complete Stone Age family tree, spanning 7 generations. Genetic studies of the remains of dozens of people in a burial site in France reveal some surprising insights into family and social dynamics of the time.

Reading someone’s facial expressions or body posture is important for understanding their personality, emotions, motivations, or intent. But can dogs draw information from faces and bodies like we do? A new study has provided the answer.

Scientists have created models of human embryos by programming stem cells. The models give a glimpse into a key stage of development that can reveal new insights into genetic disorders and preventing failure in early pregnancy.

Scientists have discovered evidence of what may be the world’s oldest known human burial. The 300,000 year-old Homo naledi remains show signs of having been intentionally buried in a chamber marked with symbols. But other scientists aren’t so sure.

A wealth of fossil evidence has pinpointed humanity’s homeland as somewhere in Africa, where Homo sapiens first diverged from earlier species about 300,000 years ago. Scientists have now identified the oldest known Homo sapiens footprints in South Africa.

The first draft of a human “pangenome,” mapping out DNA variations in our genes, has been published. Building on the existing reference genome by adding 1,000 new gene mutations and 120 million base pairs, it's crucial for future genetic research.
