Applying eyedrops is difficult in space, where there is almost no gravity. A KAIST research team has developed a wearable patch that delivers eyedrops to the eye without relying on gravity. The research team was led by Professor Ki-Hun Jeong from the Department of Bio and Brain Engineering, in collaboration with a research team led by Professor Se Joon Woo from Seoul National University Bundang Hospital. The paper is published in the journal Sensors and Actuators B: Chemical. https://phys.org/news/2026-10-eyedrops-space-wearable-patch-approach.html Space Exploration Tue, 20 Oct 2026 17:00:04 EDT news711719304 From The Traitors to everyday life, we often mistake nervousness, confidence or group suspicion for signs of deception.

Early analysis of the inscriptions discovered at Cova Dones reveals that a female deity was worshipped at the site and that women had a prominent role in rituals there—highly unusual in Roman society. https://phys.org/news/2026-10-largest-roman-cave-inscriptions-spain.html Archaeology Tue, 20 Oct 2026 12:20:15 EDT news711711363 It looks like a small, transparent patch with a rainbow on its surface—or for those old enough to remember, the back of a CD.

Components cannot be miniaturized indefinitely, and clock speeds cannot be increased indefinitely. At the same time, huge AI data centers are being built in many places, and these consume an immense amount of electricity. This is why scientists around the world are searching for novel materials that can replace or complement silicon technology and consume significantly less electricity. https://phys.org/news/2026-10-rays-reveal-copper-oxide.html Condensed Matter Mon, 19 Oct 2026 11:40:06 EDT news711621013 A bumblebee-like insect that was last seen in France 150 years ago was spotted again in the Paris region in 2025. https://phys.org/news/2026-10-painstaking-task-world-species.html Plants & Animals Mon, 19 Oct 2026 05:20:02 EDT news711601091 A shipwreck off the coast of Turkey is the oldest shipwreck in the world, our team of archaeologists believes.

Researchers from ULiège and Humboldt University in Berlin have, for the first time, analyzed these pigments one by one and discovered that some detect red light that very few animals can perceive.

What's more, almost all genes occur as two copies—one from each parent—that aren't necessarily turned on and off in sync.

If it remains undetected, it can spread to partners and to babies during pregnancy, causing lifelong effects. https://phys.org/news/2026-10-rapid-syphilis-layered-nanoparticles-infection.html Bio & Medicine Fri, 16 Oct 2026 12:00:05 EDT news711364981 Limbs evolved as a means of locomotion. From the primitive rotating flagella of bacteria to the wings of flies and even our own legs, animals use these appendages to travel to find food or mates or escape predators. But in countless species across the animal kingdom, limbs are repurposed to create elaborate social displays: Birds of paradise fan out their wings and hop around in courtship dances, while crabs wave their claws to communicate to potential mating partners. As humans, we use our limbs to dance, gesture while talking, wield tools and conduct a remarkable diversity of behaviors.

One parent might insist their child's homework has to be finished before they're allowed to use devices. The other may think a bit of screen time before studying is perfectly reasonable.
