A three-year study of nearly 4,000 adults ranging from age 19 to 94 found that brain health can improve at any age, challenging the common belief that mental sharpness must decline as we get older。 Participants spent just a few minutes a day on brain-training activities, and researchers found measurable gains across multiple aspects of brain health
A long-overlooked organ may hold surprising clues to healthy aging and cancer survival。 Researchers at Mass General Brigham used AI to analyze CT scans from tens of thousands of adults and found that people with healthier thymuses—a small immune-system organ once thought to become largely irrelevant after childhood—lived longer and had substantiall
As tech giants rush to build infrastructure, some residents who live near data centers say a constant low-frequency vibration is ruining their health and homes
Researchers found that highly drug-resistant bacteria from hospitals are also resistant to glyphosate, a commonly used weedkiller。 The discovery suggests that agricultural herbicides may be helping antibiotic-resistant microbes survive and spread far beyond healthcare settings
The race to build data centers in space is gaining momentum as AI drives unprecedented demand for computing power。 Orbital facilities could tap into abundant solar energy and avoid many of the environmental challenges faced on Earth。 Yet space remains a harsh and expensive place to operate, with major hurdles including cooling, maintenance, radiati
Oxford physicists have created an entirely new type of Schrödinger’s cat-like quantum state using components that are themselves highly quantum in nature。 The advance could open new possibilities for more resilient quantum computers and deeper insights into the strange rules that govern the quantum universe
Scientists are beginning to explore a hidden world of thousands of food chemicals that go far beyond the nutrients listed on nutrition labels。 This “nutritional dark matter” may hold the key to understanding disease risk, healthy aging, and why different diets affect people in dramatically different ways
Humans evolved to pay close attention to danger, but today that instinct is being overwhelmed by an endless supply of bad news from around the world。 Researchers say the answer isn’t to stop following current events—it’s to build healthier habits around how, when, and where we get our news
A new international study finds that middle-aged Americans are lonelier, more depressed, and experiencing worse memory and health than earlier generations。 Researchers say growing financial strain, weaker social supports, and chronic stress may explain why the U。 is falling behind other wealthy nations
At least three coal plants have been repeatedly cited for violating environmental regulations
The department cited national security concerns, saying Elon Musk’s company had played a crucial role in the Iran war。 It also argued it has the authority to stop environmental lawsuits brought by citizens
Scientists at RIKEN have proposed a new way to make quantum systems synchronize in only one direction—like a one-way street for sound particles known as phonons。 The breakthrough combines two quantum effects to create a form of one-way quantum synchronization that remains surprisingly stable even when exposed to manufacturing flaws and environmenta
Scientists discovered that Heliconius butterflies have evolved an extraordinary lifespan, living several times longer than closely related species。 Even more surprising, some show little sign of physical decline as they age。 Their unusual pollen-feeding lifestyle may play a role, but the research suggests deeper evolutionary changes are also helpin
