Can two points on a face tell us whether someone is really opening their mouth?
It sounds almost too simple. Yet behind this question lies an interesting intersection of computer vision, mathematics, and biometric security.
In a new article for The Research Code, Hangga explores how facial contours can be converted into coordinates, how a simple Euclidean-distance calculation can turn those coordinates into an observable signal, and how that signal can contribute to a broader face-liveness workflow.
But the mathematics is only part of the story.
A distance measurement is not the same as proof of liveness. The article also examines the effects of face scale, head pose, image quality, individual variation, thresholds, and potential replay or manipulated presentations.
The broader lesson is important: a mathematically correct measurement can still have significant limitations when applied to a real-world security problem.
Read the full article and explore how two points → one distance → one decision can become a useful example of mathematical reasoning in computer vision and security.

Nuts: How much is healthy? Which ones? Raw, roasted or soaked?
Nuts are among the healthiest foods you can add to your diet. But there is a lot of confusion around them:
âť“How many should you eat?
âť“Are almonds better than peanuts?
âť“Should you soak them overnight?
âť“Are roasted nuts unhealthy?
âť“Are nuts the same as dry fruits?

NASA has released one of the most detailed visualizations ever created of Earth’s ocean currents.
Using data from satellites and advanced ocean models, the map reveals massive rivers of moving water, swirling eddies hundreds of miles wide, and the powerful Gulf Stream carrying warm water from the Gulf of Mexico across the Atlantic.

For my first post, I’m sharing a letter @NVIDIA signed on why open models matter.
AI will transform every industry, power every company, and be built by every country.
Open models strengthen safety and cybersecurity, accelerate innovation and diffusion, and enable sovereignty.
The world needs both frontier closed models and frontier open models.

🚨 Scientists Just Discovered a Hidden Role for Ovaries After Menopause
What if ovaries don't actually "shut down" after menopause?
New research suggests they may switch from reproduction to supporting the immune system. Scientists found that postmenopausal ovaries become active with immune cells and may influence aging, inflammation, and overall health. It's a surprising discovery that's changing how researchers think about menopause.

Scientists have created one of the most detailed 3D reconstructions of a human cell (eukaryotic cell) ever produced.
This groundbreaking model, often termed a "Cellular Landscape Cross-Section Through a Eukaryotic Cell," combines data from X-ray tomography, nuclear magnetic resonance (NMR), and cryo-electron microscopy to map molecular structures in extreme detail.

Coffee is NOT just a wake-up drink.
Coffee contains hundreds of biologically active compounds, including polyphenols and antioxidants. In fact, for many people, coffee is one of the largest sources of antioxidants in the diet.

Yesterday: Faecalibacterium prausnitzii depleted in Parkinson's disease.
Today: the same bacterium, a different brain disease ... Alzheimer's.
In Alzheimer's, its depletion triggers a completely different chain — one that targets the blood-brain barrier and drives neuroinflammation from the inside.

MELATONIN FOR SLEEP: What Most People Get Wrong
Melatonin gummies and tablets have become hugely popular. Many people take them every night hoping for "better sleep."
But what exactly is melatonin, and who benefits from it?
A thread examining the evidence for and against melatonin.

What is melatonin?
🔸Melatonin is a hormone naturally produced by the brain (pineal gland), mainly after sunset. Its primary role is to regulate the body's internal clock (circadian rhythm). Think of it as a "darkness signal" rather than a sleeping pill.
