Researchers uncover surprising links between smell and the body’s final signals.

Most of us think of death as something sudden or distant, an event that arrives without warning. But a growing body of research suggests the human body may begin sensing the end much earlier than we realize.

Scientists are finding that subtle biological signals can emerge well before obvious decline, and some of the earliest may involve changes in smell. It’s an unsettling idea, but one that highlights how closely our senses are tied to overall health.

Researchers say the nose, often overlooked, may detect internal shifts that signal the body is beginning its final transition long before consciousness fades.

This in-between state challenges long-held ideas about where life truly begins and ends.

Scientists are beginning to explore what some describe as a “third state” that exists between life and death, where cells remain active even after the body has stopped functioning. Research has shown that certain genes and cellular processes continue for hours, or even days, after death.

Some experts suggest this liminal phase could hold clues about consciousness and how life is defined at the cellular level. While highly debated, these findings challenge traditional views of where life ends—and hint at mysteries science is only beginning to uncover.

Sleep science suggests early mornings don’t work the same way for everyone.

Waking up at 5 a.m. has become trendy in productivity culture, but sleep and health experts say that early alarm isn’t a one-size-fits-all shortcut to a better day. Your body clock, known as your circadian rhythm, regulates sleep and wakefulness based on light exposure and genetics, and it doesn’t run the same for everyone.

Most adults are neither natural early birds nor perfectly matched to a pre-sunrise routine, so forcing a 5 a.m. start can lead to grogginess, lower performance, and even health problems when sleep is lost or mistimed.

Instead of fixating on a specific hour, experts recommend aligning your wake-up time with your biological rhythm, keeping it consistent each day, and making sure you actually get enough sleep.

Researchers say these shared experiences appear across cultures, ages, and medical settings.

Near-death experiences often reveal a range of vivid sensations and perceptions occurring at the moment of death. These phenomena include seeing lights, feeling peace, or sensing loved ones, with explanations rooted in neurological activity.

The neuropsychology unit at the University of Southampton reports that such experiences reflect complex brain processes rather than purely supernatural events.

Understanding these reports helps clarify the interplay between consciousness and brain function as life ends, highlighting both biological and psychological factors involved.

Researchers found meal timing alone didn’t improve key metabolic markers.

Intermittent fasting and time-restricted eating have become mainstream diet trends, often touted as metabolic and heart-health boosters.

But a new study found that when women ate the same number of calories, narrowing their eating window didn’t improve blood sugar, blood pressure, cholesterol, or other key markers after two weeks.

Researchers also observed shifts in circadian rhythms tied to meal timing, hinting that the timing of food influences internal clocks. But when it comes to metabolic improvements, energy balance remains crucial.

Researchers are seeing meaningful progress after decades of setbacks.

A baldness “cure” isn’t a single solution. Hair loss happens for different reasons, and most people asking this question are talking about pattern hair loss, where follicles gradually shrink but often remain alive for years. That distinction matters, because living follicles can sometimes be reactivated.

For decades, treatment options barely changed. Most therapies focused on slowing loss rather than restoring growth. That’s why recent research aimed at waking up dormant follicles has generated renewed optimism.

At UCLA, researchers behind a topical compound now developed by Pelage Pharmaceuticals have reported encouraging early trial results, suggesting hair loss science may finally be entering a new phase.

Sudden flashes, blind spots, or zigzags don’t always come from your eyes.

If your vision suddenly flickers, blurs, or fills with shimmering shapes, it can feel frightening, especially if it happens without warning. Many people immediately worry about eye damage, a stroke, or something permanently wrong, because vision changes are hard to ignore and difficult to explain in the moment.

In many cases, the cause is not the eye itself. These strange visual effects can start in the brain and often fade on their own within a short period of time, leaving no lasting damage.

Knowing what an ocular migraine is, what it typically looks like, and how to respond can help you stay calm, protect yourself during an episode, and recognize when medical care is actually needed.

It spreads fast, hits hard, and often shows up before you realize what’s happening.

Norovirus is often brushed off as a short-lived stomach bug, but its ability to spread with astonishing speed makes it far more disruptive than many people expect. One infected person can unknowingly trigger outbreaks in homes, schools, workplaces, and travel settings within a matter of days.

What sets norovirus apart is how little exposure it takes to get sick and how long the virus can linger on surfaces. People are frequently contagious before symptoms appear, which allows the virus to move through groups silently and efficiently.

Understanding how norovirus spreads, how long it remains contagious, and what actually helps stop transmission can mean the difference between a brief illness and a much wider outbreak that keeps cycling through a community.

Ink doesn’t just sit in your skin; what it does next could surprise your immune system.

When you get a tattoo, needles deposit pigment deep into the skin. Most people think the ink stays right where it was placed. But science is beginning to show the story is more complex. Tattoo ink can travel, interact with the immune system, and remain in the body for months or years.

Recent studies in animal models and human tissue show that tattoo pigments don’t always stay in the dermis. They can drain into the lymphatic system, where immune cells try to clean them up. That process can trigger inflammation, change immune responses, and even alter how the body reacts to vaccines.

Researchers stress that this does not mean tattoos are inherently dangerous, but it does mean the immune system may respond in unexpected ways when ink leaves the skin and enters deeper tissue.
