Kang’s invention won second place and an award of $175,000 at the 2026 Regeneron Science Talent Search, the oldest and most prestigious science, technology, engineering and math competition for high school students in the United States.

This High Schooler Developed an A.I. Tool to Diagnose Autism and ADHD Using the Retina

Edward Kang’s RetinaMind analyzes patients’ retinal images and accurately diagnoses neurodevelopmental disorders 89 percent of the time

The researchers studied neural activity in 16 participants with epilepsy who had electrodes in their brains.

We Use Many of the Same Brain Cells to See and to Imagine Objects, a Study Suggests. The Findings Provide a New Window Into Memory

While past research has hinted at an overlap in relevant brain regions, the new work drills down to the cellular level. The discovery could help improve treatments for memory disorders, such as dementia, and certain psychiatric conditions, like schizophrenia

Cool Finds

The Earliest Known Vertebrates Had Four Eyes—and They Worked a Lot Like Ours Do, New Research Suggests

Two of those eyes may have evolved into a part of the brain called the pineal gland

Golden apple snails have eyes that are similar to humans’—and they can regenerate an amputated eye in just a month. Scientists uncovered a gene related to that process, laying the groundwork for more research that could help humans with eye injuries.

Eight Fascinating Scientific Discoveries From 2025 That Could Lead to New Inventions

By studying the natural world, scientists find blueprints for innovations that can improve human lives—in the genes of a shark, the fur of a polar bear and the flipper of an extinct reptile

For Some Male Pheasants, Love Really Is Blind. Their Elaborate Feathers That Impress Females Also Obstruct Their Vision

The adornments on the heads of male Lady Amherst’s and golden pheasants partially block their sight, according to new research, marking the first known sex-based differences in field of vision within bird species

Participants received retinal implants that restored some of their vision.

The device could be a boon for millions with vision loss from advancing age

Subtly different brain areas light up in response to viewing certain colors, a new study suggests.

Do We See the Same Colors as Others? Study Suggests Brains Respond to the Same Hues in Similar Ways

Using MRI scans, researchers found that participants’ patterns of brain activity were alike when looking at certain colors. But people can still experience those colors differently

Golden apple snails and humans have similar eyes with related structures. Understanding how the snails can regrow them could help scientists heal human eyes.

This Snail Can Regrow Its Eyes—and Understanding How May One Day Help Humans With Injuries

Researchers pinpointed a gene related to eye development in golden apple snails, which can regenerate amputated eyes within about a month

A study participant puts in a contact lens. Researchers developed lenses with nanoparticles that convert infrared wavelengths into visible light that humans can perceive.

New Contact Lenses Give Users Super-Vision to See Infrared Light—Even With Their Eyes Closed

Researchers have developed experimental contact lenses that use nanoparticles to convert the invisible wavelengths of near-infrared light into visible colors

Humpback whales have poorer eyesight than previously thought, according to a new study.

Humpback Whales Can’t See as Well as Scientists Thought, and It Might Explain Why They Keep Getting Tangled in Fishing Gear

Despite having big eyes, the whales can’t make out details of objects more than a few body lengths away, according to a new study

New research is revealing how climate change is impacting our eyes.

Climate Change Is Threatening Eye Health in Disturbing Ways

Cataracts, pinkeye and other ocular disorders are linked to heat, air pollution and higher UV exposure

Human perception of color is regulated by three types of cone cells in the eye. By artificially stimulating just one type with a laser, researchers and study participants experienced a new color they call "olo."

Scientists Say They’ve Discovered a New Color—an ‘Unprecedented’ Hue Only Ever Seen by Five People

The color, dubbed olo, is described as an intensely saturated teal. Researchers say it might have applications in understanding color blindness

Surgeons operated on three patients in Canada.

Surgeons Are Conducting Rare ‘Tooth-in-Eye’ Surgeries to Restore Vision to Blind Patients in Canada

The complex procedure involves extracting a patient’s canine tooth, adding a plastic optical lens to it and surgically embedding it in the eye

More than 3,000 known dragonfly species exist.

14 Fun Facts About Dragonflies, From Their Lethal Hunting Prowess to Incredible Migratory Feats

The colorful insects can help humans by eating mosquitoes and will gather in mysterious swarms

By examining the fossils of ancient creatures, scientists are able to see the origins of features that make mammals different from other animals.

How to Make a Mammal in Nine Evolutionary Steps

From the formation of inner ear bones to the rise of hair to cover our bodies, these developments made us distinct from other animals

A new study suggests that coyotes, like the ones seen here, have the same face muscle as dogs that's used to make pleading "puppy eyes."

Coyotes Might Make ‘Puppy Eyes,’ Suggesting the Facial Expression Evolved for More Than Just Cuteness

The wild canines have the same muscles used by domestic dogs to create the wide-eyed, pleading look that captures humans’ hearts

The viewfinders were installed at all 43 Virginia state parks.

Virginia State Parks Install Viewfinders for People With Colorblindness, Just in Time for Leaf-Peeping Season

The viewfinders are outfitted with special lenses that help people with red-green colorblindness distinguish between hues

African wild dogs might use facial expressions to communicate with each other as they hunt in packs on the savanna.

Wild Dogs Have Muscles for ‘Puppy Eyes,’ Suggesting the Cute Expression Did Not Evolve Just for Humans

African wild dogs have the same well-developed eye muscles that domestic dogs use to make their signature pleading faces, a recent study finds

While spiders can have up to eight eyes, daddy longlegs, which belong to a different order of arachnids called harvestmen, usually have just two eyes.

Daddy Longlegs Have Four Extra, Hidden Eyes, Researchers Say

The new discovery could help scientists unravel the mystery of how the arachnids evolved across some 537 million years

Humans may perceive dogs with dark eyes as younger and more friendly, according to new research.

Here’s Why Most Dogs Have Brown Eyes

Humans may have bred their canine companions to have darker eyes, because we perceive them as younger and more friendly, study finds
