An Early Clue to Alzheimer's May Appear as Young as 45, Study Finds
NEWS | 22 May 2026
But as our new research suggests, blood biomarkers in combination with self-reported memory concerns could offer an early clue to how Alzheimer's disease develops across the life course. In recent years, we've seen advances in pharmaceutical treatments for Alzheimer's disease. It is likely these treatments work best when taken early, which makes it more important to identify the earliest signs of Alzheimer's disease. In the past, Alzheimer's disease could only be definitively diagnosed postmortem, or more recently, with invasive testing such as a lumbar puncture. Studying middle-aged populations is therefore important for identifying early risk profiles for Alzheimer's, long before the disease would be diagnosed.

Spinach-Based Eye Drops Could Help Treat a Common Eye Condition
NEWS | 22 May 2026
Led by a team from the National University of Singapore (NUS), the researchers borrowed photosynthetic membrane stacks from spinach leaves, applied via eye drops to lab-grown human eye cells, and to the eye cells of mice engineered to have a condition similar to dry eye disease. NADPH is crucial in countering reactive oxygen species (ROS) that drive inflammation and cellular stress in dry eye disease. Thylakoids are the crucial NADPH-generating components of chloroplasts, the structures that carry out photosynthesis in plant cells. What's more, the process was also shown to be effective in tear samples taken from patients with dry eye disease. In mice treated twice daily for 5 days, the LEAF treatment outperformed Restasis, which is commonly prescribed for dry eye disease.

Scientists May Finally Know Why T. Rex Had Such Tiny Arms
NEWS | 22 May 2026
You probably wouldn't say it to its face, but the famously fearsome Tyrannosaurus rex has long been the butt of tiny arm jokes. As such, their arms shrank over time with disuse, until they became the funny little chicken wings we laugh at today. At the same time, sauropod dinosaurs were ballooning into the largest land animals ever to walk on Earth. Stranger still, the team found that, across different lineages, the arms shrank by different proportions. Others even hypothesize that T. rex evolved short arms so they wouldn't accidentally be bitten off by frenzied relatives around the dinner table.

The Great Pyramid Has Survived 4,600 Years. A Strange Feature May Help Explain Why.
NEWS | 22 May 2026
Somehow, while the rest of the ancient Egyptian world has crumbled around it, the Great Pyramid of Khufu at Giza remains standing, even after 4,600 years. Archaeologists are still trying to uncover the full complement of engineering ingenuities that led to the Great Pyramid becoming the sole surviving member of the Seven Wonders of the Ancient World. As a mostly solid structure, the pyramid is extremely sturdy, with its weight concentrated towards the ground and distributed across the base. Egypt is not especially prone to earthquakes, but at least two major ones have been recorded within an 80-kilometer (50-mile) radius of the Great Pyramid. As the largest pyramid still standing and one of the oldest, the Great Pyramid got researchers wondering: Why has this enormous, ancient structure survived where others have fallen?

Study Shows Meat Eaters Are More Likely to Live to 100, But There's a Catch
NEWS | 22 May 2026
Among more than 5,000 people aged 80 and over, researchers found that female meat eaters were more likely to reach age 100 than female vegetarians. It was only vegetarian participants deemed underweight who were less likely to live to 100 than meat eaters. What's more, vegetarians who ate fish, dairy, or eggs had a similar chance of reaching 100 as meat eaters. Nutrition, however, is an extremely complex area of research, and health outcomes can be influenced by a plethora of societal, environmental, and individual factors. Still, not all meat is equally associated with negative health outcomes, and the amount can matter.

An Early Warning Sign of Alzheimer's May Be Keeping Some Women Up at Night
NEWS | 22 May 2026
Researchers have now discovered more evidence that, for some women, poor sleep may be an early sign of the disease. We know that poor sleep quality increases Alzheimer's risk, and that Alzheimer's interferes with sleep, likely due to the build-up of tau protein tangles in the brain. But whether poor sleep is a risk factor or a symptom of Alzheimer's disease remains unclear. "Improving sleep may be a potential intervention target for Alzheimer's disease mitigation and prevention, particularly for older women." The research has been published in the Journal of Prevention of Alzheimer's Disease.

These Popular Supplements Are Sold With Anti-Aging Claims. Here's What Science Says.
NEWS | 22 May 2026
Among the most heavily marketed compounds are NAD+, NMN, and resveratrol, often described as supporting cellular repair, energy production, and healthy aging. To make sense of the claims, it helps to separate three things: the molecule NAD+, the compounds sold to raise it, and the products, such as supplements, creams, and serums, that contain them. frameborder="0″ allowfullscreen="allowfullscreen">In animal studies, NAD+ precursors have produced promising results. So, are NAD+, NMN, and resveratrol the elixir of youth? Supplements may eventually prove useful, but at present, the evidence for staying younger for longer is much stronger for everyday habits than for anti-aging products.

Two Ancient Clues May Finally Explain Why 90% of Us Are Right-Handed
NEWS | 22 May 2026
It doesn't matter where you're from or what cultural background you have – about 90 percent of people are right-handed. We prefer one hand over the other because we walk on two legs – and our bigger brains decided the right hand was favored. Archaeological evidence, first reported in 2016, suggests that hominins were favoring their right hands as far back as 1.8 million years ago. Our older ancestors, such as Australopithecus afarensis, only showed slight preferences for their right hands. But why then did 90 percent of us 'choose' our right hands, in what should be essentially a coin toss?

De-Extinction Company Says It's Hatched Chicks From Artificial Eggshells
NEWS | 22 May 2026
Independent scientists say the technology, while impressive, lacks some components to be truly considered an artificial egg. To hatch the chicks, Colossal scientists poured fertilized eggs into the artificial system and placed them in an incubator. "That's not an artificial egg because you've poured in all the other parts that make it an egg. In decades past, researchers have used cruder technology to create transparent eggshells that hatched chicks from plastic films or sacks. There's a long road ahead before Colossal attempts a moa resurrection using this artificial egg system.

A Beluga Whale Showed a Sign of Intelligence Once Thought Unique to Humans
NEWS | 22 May 2026
More than 20 years ago, four female beluga whales were kept together at the New York Aquarium of the Wildlife Conservation Society. This offered scientists – including marine mammal expert and cognitive psychologist Diana Reiss – a rare opportunity to conduct a mirror test of self-recognition on the whales. If you've ever abashedly wiped a smudge from your chin on seeing your reflection, you've passed the mirror test for self-recognition. Chimpanzees, dolphins, elephants, and Eurasian magpies are among those who have passed the test. Animals who pass the mirror test tend to be social creatures, which is why belugas seemed good candidates.

Your Daily Rhythms May Help Slow Biological Aging, Study Suggests
NEWS | 22 May 2026
We're all a certain number of years and months and days old, but alongside this chronological age is a biological age: the rate at which our bodies are wearing down. Now it appears that steady and settled daily rhythms – with regular, consistent time carved out for both rest and activity – might help to slow down this biological aging. The new findings suggest that these changes might be directly linked to biological aging. These clocks all use blood biomarkers in slightly different ways to assess biological age, looking at chemical markers on DNA that signify wear and tear. While the clocks didn't all agree exactly, there were significant associations between regular and predictable routines, and slower biological aging.

Scientists Discover a Fat-Burning 'Dial' That Could Help Strengthen Bones
NEWS | 22 May 2026
The study, led by a team from McGill University in Canada, focuses on brown fat (or adipose tissue), which the body holds in smaller amounts than white fat. "That opens the door to understanding how multiple energy‑burning systems work together to keep the body warm at the just-right temperature." The discovery was made through a careful examination of brown fat in mice exposed to the cold, and the chemicals that accumulated. Advanced 3D mapping of the enzyme revealed how: Glycerol binds to a specific cavity in TNAP, which the researchers dubbed the 'glycerol pocket'. It's early days to talk about treatments, but identifying how this brown fat heat-producing pathway is turned on is a major step towards controlling it.

A Signal of Cognitive Decline May Be Hidden in The Way You Write
NEWS | 22 May 2026
Simple, reliable tests to identify cognitive decline earlier in life and track it over time can make a real difference to treatment and support. "Tasks involving higher cognitive demands showed that cognitive decline is reflected in how efficiently and coherently handwriting movements are organized over time." Of these, 38 had been diagnosed with some form of cognitive impairment, while the remaining 20 hadn't and were considered cognitively healthy. In contrast, other features can remain relatively preserved, especially in the early stages of cognitive decline, making them less sensitive indicators." There might even be opportunities to detect cognitive decline earlier through handwriting – before noticeable symptoms like memory loss set in.
