We can trace our human evolutionary lineage back to fish.
Some of the same genetic mutations can lead to FTD, ALS or symptoms of both.

FTD leads to changes in personality and behavior. Understanding its genetic and molecular causes could lead to new ways to treat neurodegenerative diseases.
Kate Legge’s husband was chronically unfaithful. So was his father, who was forced to leave the family home after revealing his mother’s affair. Legge reflects on generational love and infidelity.
Most clinical trials overrepresent young white males.

Medicine works better when the treatments are tailored to fit each individual person’s biology and history. A first step is increasing diversity in clinical trials, but the end goal is precision medicine.
The little-known eating disorder Arfid usually develops in childhood.

An estimated 1-5% of people globally suffer from avoidant restrictive food intake disorder.
When species naturally hybridise, the influx of genes can reduce their risk of extinction as climate change shrinks their habitats.
The immortal jellyfish ‘Turritopsis dohrnii’ is capable of escaping death. The molecular keys involved in its longevity have been revealed by researchers at the University of Oviedo.
When it comes to eye care, regular visits to the optometrist or ophthalmologist can detect the early signs of diabetic damage.
The risk of developing eye complications is high in young people with Type 2 diabetes, which is increasingly affecting children and adolescents, especially those who are more sedentary.
More people moved into Scandinavia in Viking times than at any other time period analysed in the study.
DNA analysis reveals a large migration of people into Scandinavia during Viking times.
Ever wondered why people can’t agree on what foods taste good?
Our experiences of taste are so vivid and personal it can be hard to imagine how people can turn their nose up at your favourite comfort food. Research shows the explanation could be in your genes.

Humanity carries traces of other populations in our DNA – and a new study shows how one of these ancestors has influenced the immune systems of modern Papuans.
X and Y chromosome.
The human Y chromosome could disappear over time, putting our species in jeopardy. But some rodents have managed just fine without it – and we now know how.
Paternal and maternal genes drive fetal development in different directions.

Genetic conflict may play a role in pregnancy complications, such as preeclampsia and gestational diabetes, as well as developmental disorders.

A recent study offers evidence that marine biology’s biggest stage is broken, and suggests ways to fix it.
Statistical pitfalls in GWAS can result in misleading conclusions about whether some traits (like long horns or spotted skin, in the case of dinosaurs) are genetically linked.
People don’t randomly select who they have children with. And that means an underlying assumption in research that tries to link particular genes to certain diseases or traits is wrong.

Women live longer than men, yet they cease reproductive life earlier than men because of the menopause. Why this apparent contradiction?

In Canada, 14.4 per cent of South Asians have Type 2 diabetes, the highest prevalence of any other ethnic group in the country. Why is this population so disproportionately affected by diabetes?
A pit bull is not an official breed – it’s an umbrella term for a type of dog.

A scholar of law and humanities compares bans on dogs with any pit bull genes to “one drop” laws that once classified people with even a single Black ancestor as Black.
Hundreds of thousands of years ago, our
Homo sapiens ancestors shared the landscape with multiple other hominins.

Ancient DNA helps reveal the tangled branches of the human family tree. Not only did our ancestors live alongside other human species, they mated with them, too.
Ethical and equitable scientific collaboration could help increase the genetic diversity of genomic data.

Existing genetic data and sequencing tools are overwhelmingly based on people of European ancestry, which excludes much of the rich genetic variation of the world.
