Stronger flu shot linked to nearly 55% lower Alzheimer's risk

A surprising new study suggests that a stronger flu shot could offer older adults significantly greater protection against Alzheimer's disease. Researchers at UTHealth Houston analyzed nearly 200,000 adults ages 65 and older and found that those who received a high-dose influenza vaccine had a nearly 55% lower risk of developing Alzheimer's, compared with a 40% reduction previously associated with the standard-dose vaccine.

Why the tropics lose the most birds when cities expand

Tropical ecosystems are famous for their teeming, exuberant diversity. In fact, the dramatic increase in biodiversity from the poles to the tropics—known as the latitudinal diversity gradient—is pervasive across branches of the tree of life, and fossil evidence suggests it has existed for millennia.

Scientists discover a hidden warning sign of cannabis addiction

A study of more than 17,700 US adults found that people who use cannabis in multiple forms have dramatically higher rates of daily consumption and addiction symptoms than those who stick primarily to one method. Nearly 67% of those who used almost every form met criteria for cannabis use disorder, compared with just 15% of people who mainly consumed edibles.

Mysterious gas leaks suggest Mars may still be volcanically alive

Mysterious gas emissions and fresh volcanic fissures suggest that Mars may not be geologically dead after all, with hot magma potentially still active deep underground. The discovery could point to hidden pockets of warmth and chemical energy capable of supporting microbial life beneath the Red Planet’s surface.

A hidden limit of space and time could unlock electronics 100,000 times faster

Scientists have discovered a surprising quantum limit that prevents electrons from being tracked with unlimited precision in both space and time. The breakthrough could pave the way for manipulating chemical reactions and developing electronics hundreds of thousands of times faster than today's technology.

Personalized savings reminders can help boost retirement savings

Private retirement savings are an increasingly important topic in public debate. One popular idea is to phrase savings reminders in one of two ways: either you emphasize what someone stands to lose if they don't save, or you emphasize what they stand to gain if they do. To date, research into which of the two reminder messages is more effective in terms of influencing people's efforts to save has produced conflicting results.

Student finds proof of rare wild cat in northern New Mexico

Armed with dozens of motion-sensing cameras, William Grooms spent this past summer documenting wildlife across Carson National Forest in northern New Mexico. It was his first field season collecting photos for a two-year study to understand how forest structure influences biodiversity in the Southern Rocky Mountains.

The hidden ways insects support animal life—from habitat to health—go way beyond being food

There are at least 14 million insect species on Earth, and they play highly diverse roles in sustaining the natural world. Insects provide many well-known benefits—what scientists often call "ecosystem services." For example, you can thank a bee or a hoverfly for pollinating wildflowers and agricultural crops, or credit dung beetles for decomposing manure and other waste materials.

Different text genres help doctoral students adapt their writing to reach new readers

An academic abstract, a blog post and a public outreach article all place different demands on the writer. Readers' prior knowledge varies, as does the purpose of the text and what needs explaining. Mastering one kind of text therefore does not automatically mean being able to write another.

Earth's gravity may have kept the early moon's volcanic heart beating

We typically think of the moon as a static, floating object that has remained the same for basically its entire lifetime, with an occasional asteroid impact serving as an exception. That understanding is grounded in physics—the moon should have cooled rapidly after forming when a huge protoplanet hit the early Earth around 4.5 billion years ago. But some lunar material returned from the Chang'e-5 mission was notably formed only around 2 billion years ago, yet appeared to be volcanic in origin.
