Vitamin D May Slow Cells’ Aging Vitamin D supplements may help prevent the loss of telomeres, DNA sequences that shrink with aging, a large study shows. But the health effects aren’t yet clear By Stephanie Pappas edited by Jeanna Bryner A new study suggests vitamin D supplements might slow cellular aging by protecting telomeres. Olga… Continue reading Vitamin D May Slow Cells’ Aging by Protecting DNA
India-UK Trade Deal Is as Much Politics as Economics
This commentary was originally published by East Asia Forum on September 9, 2025. The India-UK Comprehensive Economic and Trade Agreement (CETA), signed on July 24, 2025, has been described as a bold effort by both governments to open their economies and deepen strategic alignment. But look more closely, and what emerges is a more complex… Continue reading India-UK Trade Deal Is as Much Politics as Economics
‘World Models,’ an Old Idea in AI, Mount a Comeback
The latest ambition of artificial intelligence research — particularly within the labs seeking “artificial general intelligence,” or AGI — is something called a world model: a representation of the environment that an AI carries around inside itself like a computational snow globe. The AI system can use this simplified representation to evaluate predictions and decisions… Continue reading ‘World Models,’ an Old Idea in AI, Mount a Comeback
Exodus: Affordability Crisis Sends Americans Packing From Big Cities
This is the first in a two-part series on America’s return to the hinterlands. For much of the past century, in both the United States and elsewhere, the inexorable trend has been for people to move from rural areas and towns to ever larger cities, particularly those with vibrant downtown cores such as New York,… Continue reading Exodus: Affordability Crisis Sends Americans Packing From Big Cities
How One Astronomer Uncovered Nearly 200 Moons—Around Just One Planet
A mere decade ago astronomers knew of just 62 moons around Saturn. Today the ringed planet boasts a staggering 274 official satellites. That’s more than any other world in the solar system—and far too many for most people to keep track of. Astronomer Edward Ashton is no exception, even though he has helped discover 192… Continue reading How One Astronomer Uncovered Nearly 200 Moons—Around Just One Planet
What Is the Fourier Transform?
As we listen to a piece of music, our ears perform a calculation. The high-pitched flutter of the flute, the middle tones of the violin, and the low hum of the double bass fill the air with pressure waves of many different frequencies. When the combined sound wave descends through the ear canal and into… Continue reading What Is the Fourier Transform?
Analog vs. Digital: The Race Is On To Simulate Our Quantum Universe
Ringbauer’s team was building a quantum computer that used not qubits but qudits — each with five possible states. The extra possibilities allowed each particle to hold more information, often reducing the number of steps needed for a complex computation. Not every simulation would benefit from being run with qudits, but the complexity of quantum… Continue reading Analog vs. Digital: The Race Is On To Simulate Our Quantum Universe

Now,… Continue reading Bird Flu Vaccine for Cows Passes Early Test
Missiles, Markets, and Mutual Interests: Poland and South Korea’s Evolving Defence-Industrial Cooperation
In recent years, South Korea has cemented its ascendancy to the global top table as a defence-industrial player. In Europe, one country has been the primary foothold enabling South Korea’s rise: Poland. Cooperation between the countries is set to grow, with the parties finalising a $6.5 billion deal to supply K2 Black Panther tanks for… Continue reading Missiles, Markets, and Mutual Interests: Poland and South Korea’s Evolving Defence-Industrial Cooperation
