These mutations may happen in response to environmental or lifestyle factors, or may be passed down through family members. Genetic testing can be important in catching certain family cancers early and ensuring patients receive the right treatment for their disease.

Rafal Smigrodzki, a neurologist with a PhD in genetics, first heard of the polygenic risk score offering after reading about it in a 2017 MIT Technology Review feature that focused on the company they eventually used, Genomic Prediction.

The sequence of DNA that we inherit from our parents encodes directions for making our cells and giving us specific traits. Identical twins have the same DNA sequence, so how can one twin end up with a genetic disorder while the other twin does not? Robin Ball explains how the secret lies in X chromosome inactivation.

A primer on genetic testing, personalized medicine, and the promise of pharmacogenomics–the use of genetics to predict an individual's response to a drug.

Since 2019, Rowling’s public statements on gender and trans issues have prompted widespread backlash, leading many fans to attempt to distance her views from the Harry Potter series.

Designer babies, the end of diseases, genetically modified humans that never age. Outrageous things that used to be science fiction are suddenly becoming reality. As scientists increasingly understand how specific genes cause disease, the possibility of engineering our genes to not only "fix" problems but enhance our natural ability grows.

The child, born in May 2020, was selected by her parents to optimize for certain health qualities based on an analysis of her multifactorial genes by a New Jersey-based company called Genomic Prediction. Her embryo was selected for implantation based on polygenic risk scores for heart disease, diabetes, and cancer.

Combining book sales, films, theme parks, and merchandise, Harry Potter ranks among the world’s highest-grossing media franchises—estimated at more than $32B in total value, alongside giants like Star Wars and Marvel.

Created by college students in 2005, the broomstick-based sport became an international phenomenon with organized leagues and World Cup tournaments. Now called Quadball, it’s played in more than 40 countries worldwide.

The world phenomenon of Harry Potter inspired millions of kids to read. The books, and the make-believe game quidditch (played by the hero), have inspired a real-life sport called Quadball, based on the fictional game involving flying broomsticks. Teacher John Ssentamu brought the game to his town of Katwadde in Uganda to bring kids—long absent from school—back to receive an education. A documentary crew filmed them playing in an inspiring story of education and community.

Computers produce so much information that researchers can't properly analyze all the data produced, and the overload can also lead computers to make mistakes. Researchers are increasingly turning to citizen scientists—members of the public who are willing to volunteer—to help them make sense of data when computers can't. This article details a few of the ways you can contribute to genetics research by playing video games.

Ali Hazlewood's "The Love Hypothesis" began as "Star Wars" fan fiction. Cassandra Clare's "Mortal Instruments" series was about "Harry Potter" characters Draco Malfoy and Ginny Weasley. Anna Todd's "After" series was an example of "real life fiction," or fan fiction that is about real people rather than fictional ones (the books were originally based on the boy band One Direction).

CRISPR is a new area of biomedical science that enables gene editing and could be the key to eventually curing diseases like autism or cancer. WIRED challenges biologist Neville Sanjana to explain this concept to 5 different people; a 7-year-old, a 14-year-old, a college student, a grad student and a CRISPR expert.

In a conversation with Ewan Birney, Director of the European Bio-informatics Institute, he discusses what it was like to be a PhD student working on the Human Genome Project in the months before the draft announcement and its impact on him and the field of genetics.

Genetic chimeras can result when cells with different DNA combine, such as when two sperm cells fertilize two egg cells, creating two embryos that then merge. In mosaicism, mutations arise within an organism after conception and can spread through cell division, resulting in diseases and forming genetically distinct anatomy.

At a conference in 1985, Canadian biochemist David H. Dolphin posited that stories of vampires and werewolves had a real-world origin. He argued that porphyria could have caused sufferers to seek out blood, as well as experience light sensitivity and an aversion to garlic. More than one article in the 1990s discredited this take.

The non-identical twins, who would also be half-siblings, result from a rare biological phenomenon called heteropaternal superfecundation. Britain's first known twins with different dads, featured in this article, learned of each other's existence in recent years, when they were both 45. They discovered each other after taking DNA tests from Ancestry, a genealogy company.

Certain gene variants can affect how quickly or slowly medications are broken down in the body, affecting drug effectiveness and the risk of drugs failing.
