Rachel Fieldhouse in Nature:
The effect of a gene can vary greatly — and sometimes be the complete opposite — depending on whether it is inherited from the mother or the father. Some genetic variants can, for instance, increase a person’s risk of developing type 2 diabetes when inherited from the father, but lower it when inherited from the mother. But such effects have been challenging to unpick owing to gaps in genomic data. A study published in Nature this week describes a statistical method used to identify at least 30 parent-of-origin effects1 in 14 genes.
When a child is conceived, it inherits two copies of almost every gene — one from each parent — and both are generally turned either on or off. But in some regions of the genome, one copy can be turned on, or expressed, while the other is silenced. This can lead to ‘imprinting’ disorders such as Prader-Willi syndrome, which is usually caused by a missing or non-functional paternal copy of the UBE3A gene on chromosome 15. In contrast, a missing or non-functional maternal copy can cause Angelman syndrome.

Two moments in Graham Greene’s published life have often returned to me in the past twenty years. This may sound strange: an ideal reader should refrain from crossing the boundary between a writer’s work and his life. And yet it is inevitable: rarely does an author have the luxury of having no known biography. Greene, having written about his life and having had his life extensively written about by others, remains near when one reads his work—not insistently dominating or distracting, as some writers may prove to be, but as a presence often felt and at times caught by a side glance.
Yes, every fashionable conference has some panel on AI. Yes, social media is overrun with hypemen trying to alert their readers to the latest “mind-blowing” improvements of Grok or ChatGPT. But even as the maturation of AI technologies provides the inescapable background hum of our cultural moment, the mainstream outlets that pride themselves on their wisdom and erudition—even, in moments of particular self-regard, on their meaning-making mission—are lamentably failing to grapple with its epochal significance.
The worst-case scenario of famine is currently playing out in the Gaza Strip.” These were the

IN 1975, JACK KIRBY, the “King of Comics” whose wildly kinetic art and sweeping visions had shaped the whole universe of Marvel Comics, sent a Hanukkah card to a friend, a young fan Kirby had met a few years earlier at a New York comics convention. At the time, Kirby had been living in Thousand Oaks, California, where he’d joined a Conservative synagogue, Temple Etz Chaim. An active temple member, Kirby occasionally read Torah portions at Shabbat services, visited the Hebrew School to demonstrate the art of drawing comics for the students, and later fulfilled a lifelong dream when he joined a congregational trip to Israel. So there was nothing remarkable about him sending a Hannukah card—except, that is, for
There are plenty of healthy activities available at home, of course, from playing with your children to pursuing a hobby. But there are also consequences to our homebody lifestyle. Time in the house is more likely to be
I have always had a soft spot for bats, and yet, after more than 500 reviews, this is the first bat book I cover here. Having now read this richly illustrated general introduction to their biology, I am even more engrossed with their many unique adaptations.
“These days, I rarely think about her. And when I do, it’s happy thoughts. Because it was so nice. Very painful, but mostly wonderful. That’s why I wrote it down. To keep it with me. I know I will never forget it, but memories change. I thought if I found the right words to describe it exactly as it was, I could capture it, make it solid. Something I could hold in the palm of my hand forever.”
