A higher-dose flu shot could spare millions of older adults a hospital stay

Influenza is a seasonal condition that causes coughing, sneezing, mild fever and aches in most cases. However, it can sometimes take a serious turn, leading to hospitalization, especially for young children, adults over 65 and pregnant people. A recent study published in JAMA Network Open examined whether the high-dose inactivated influenza vaccine (HD-IIV), which contains four times as much antigen as the standard dose, offers superior protection against hospitalization and death.

AI tracks missing hydrogen atoms in crystals with 97% success rate

Artificial intelligence is often used to generate images. In research, specialized AI models are used for scientific applications—for example, to predict the positions of atoms in materials. The MatterGen model developed by Microsoft can generate complex crystal structures from just a few pieces of information—which atoms should be present and in what proportions—and researchers can then use these structures for computer simulations of new materials.

A cornerstone of Milky Way history may need rewriting with evidence of multiple ancient mergers

Astronomers may have uncovered new details about one of the Milky Way's most important ancient collisions. Using data from the Dark Energy Spectroscopic Instrument (DESI) and a new clustering algorithm, researchers have found evidence suggesting the famous Gaia-Sausage/Enceladus structure (GSE) has a far more complicated origin than previously thought.

Do you lose your whole day to one appointment? 'Waiting mode' may be why

You have a 3 p.m. appointment. It's now 10 a.m., and somehow your entire day already feels out of reach. Maybe you find yourself unable to start anything properly. You feel on edge, waiting for something to begin or end. You check the time again and again. Even a positive, planned event, like a friend visiting later, can leave you feeling stuck.

New findings complete first evolutionary history of all living millipede orders, dating back 460 million years

Long before vertebrates walked on land, millipedes had the place to themselves. Hundreds of millions of years before dinosaurs arrived, these early decomposers were helping establish Earth's terrestrial ecosystems. But despite their ancient history, scientists still hadn't fully unraveled their evolutionary story.

Photo: Hubble and Webb offer new view of Black Eye Galaxy

This March 20, 2026, image of Messier 64, or the Black Eye Galaxy, is a composite view from NASA's Hubble Space Telescope and James Webb Space Telescope. It shows Messier 64 captured at near- and mid-infrared wavelengths by Webb, while Hubble's image shows the galaxy in ultraviolet, visible, and near-infrared light.

Flu infection may weaken tuberculosis defenses by disrupting key immune pathways

New research from Imperial College London suggests that infection with the influenza virus may leave people more susceptible to tuberculosis. The findings suggest that seasonal flu vaccines could offer a potential new strategy for preventing and controlling tuberculosis in regions around the world where prevalence is high and people are at high risk.

COPA mutations reveal alternative trigger for small intestine tumors

A signaling system known as the Wnt pathway plays a central role in how cells in the intestine grow, divide and renew themselves. Decades of research have shown that disruption of this pathway is a defining feature of many intestinal cancers. In particular, mutations in the APC gene—which normally acts as a brake on Wnt signaling—are widely recognized as a key initiating event in colorectal tumors.

Hubble captures galaxy swarm with lensed arcs from early universe

Looking somewhat like a swarm of bees returning to their hive, this NASA Hubble Space Telescope image features the galaxy cluster MACS0329-0211. Galaxy clusters like MACS0329-0211 are important signposts in the story of how the structure of the universe evolved, and are the ultimate telescopic lenses, placing gravitationally lensed galaxies from the earliest stages of the universe into our view.

Would you buy milk from a gene‑edited cow? Consumers may be more open than you think

As temperatures rise, New Zealand's dairy farmers face a growing challenge: keeping cows cool enough to remain productive. Heat stress can reduce milk production, harm animals and lower the environmental efficiency of dairy farming. For an economy so heavily reliant on dairy exports, the stakes are significant.

Why birds ignore Newton: New theory could sharpen models of flocks, crowds and cells

Birds in flocks, bacteria and cells: In many collective systems, individual elements respond to only part of their surroundings, seemingly defying Newton's third law of motion—action equals reaction. These exceptions are known as nonreciprocal interactions. A Dresden physics team working with Roderich Moessner, a founding member of the Würzburg–Dresden Cluster of Excellence ctd.qmat, has now developed a theory that makes it possible to describe these interactions efficiently and simulate them far more precisely.

Parkinson's medication shows promise in treating treatment-resistant depression

For many people who suffer from depression, the condition is not just about feeling down but also about a loss of motivation and difficulty finding pleasure in activities they used to enjoy. A new study conducted in Sweden shows that a medicine used to treat Parkinson's disease can be used as an add-on therapy to alleviate these symptoms in some patients with treatment-resistant depression. The study has been published in Nature Medicine.
