Despite decades of starts and stops, new treatments and key genetic discoveries are giving researchers great hope for slowing or eventually preventing Alzheimer’s disease.
Pharmacogenetic testing is a form of precision medicine, using your genes to personalize your care.

Genetic testing can help take the guesswork out of finding the right treatment. For certain diseases. To an extent.
Unlike human eyes, dogs’ eyes are located more to the side of the skull. That gives them a wider field of vision.
Your faithful companion sees the world differently than you do, but it’s a mistake to assume dogs only see black, white and shades of grey.
A failed experiment led to researchers showing that assumptions about chromosomal behaviour were wrong.
A failed experiment led the researchers to question their assumptions and realize that, contrary to popular belief, chromosomes interact with and affect genetic expression.
Ötzi was found in 1991 in the Alps near the Italian-Austrian border.
We can predict hair and eye colour with reasonable accuracy from DNA, but other characteristics are being investigated.

New research sheds light on the interconnected nature of the human genome and what this means for future gene therapies.
Women are more likely to develop chronic diseases driven by the immune system.
Sub-Saharan Africa is the region with the highest prevalence of sickle cell disease.
The sickle cell disease burden in west Africa is among the highest in the world.
As an animal model, the zebrafish offers many advantages that save researchers time and money.

Of the many qualities that make the zebrafish a model organism, the fact that it shares 70% of the genes humans have makes it an ideal candidate for developmental biology research.
Endurance isn’t the only type of fitness linked to genetics.

A growing body of evidence shows there are links between our genetics and fitness.
The same amino acid can be encoded by anywhere from one to six different strings of letters in the genetic code.

Many of the amino acids that make up proteins are encoded by genetic material in more than one way. An information theorist explains how principles of nature may account for this variance.
For many people with fragile X, the mutated gene that causes symptoms is active rather than silenced.

Fragile X syndrome is the most common inherited form of intellectual disability. Using short bits of DNA to fix improperly transcribed genes may one day be a potential treatment option.
For many people, trying to lose excess fat is very difficult without help. Effective treatment is available when obesity affects health.
Despite the prevalent view that people with large bodies should simply eat less and move more, it’s nearly impossible to fight our genetic heritage or other factors that are not within our control.
A new study published in Nature suggests a particular gene mutation could help explain why some people are asymptomatic. A virologist explains.
Participants in biobank studies are often asked for broad consent to use their data.

Biobanks collect and store large amounts of data that researchers use to conduct a wide range of studies. Making sure participants understand what they’re getting into can help build trust in science.
Since Folbigg was convicted in 2003, there have been nearly 3,000 additional single genes identified, whose different mutations can cause over 6,250 different diseases.
A healthy mind in a healthy body? Here’s what the science says.
One genetic study of over a quarter million people highlights the cognitive benefits of exercise, while another, based on 30 years of scientific literature, says the opposite. Who’s right and who’s wrong?
A casual stroll on the beach can leave enough intact DNA behind to extract identifiable information.

Environmental DNA provides a wealth of information for conservationists, archaeologists and forensic scientists. But the unintentional pickup of human genetic information raises ethical questions.
Climate change is bringing heightened droughts, heat stress and floods. For our fruit trees, that means tougher conditions. To prepare means mining their genomes to hunt for resilience.
The roaming Steller’s sea eagle in Georgetown, Maine, Jan. 1, 2022.
A Steller’s sea eagle, native to the Asian Arctic, has traveled across North America since 2021. A scholar questions whether the bird is lost – and how well humans really understand animals’ actions.
