Healthy aging with furry friends

Healthy aging with furry friends

With longer lives comes the challenge of achieving healthy aging, often defined as staying disease- and disability-free for as long as possible. Frailty prevention has thus become a key focus for promoting successful aging. Among various strategies, pet ownership, particularly of dogs, has emerged as a potential contributor to maintaining

How ant brains use moonlight for navigation

How ant brains use moonlight for navigation

Ants use polarized light from both the sun and the moon to navigate. Polarized light, which is light waves vibrating in a specific direction, serves as a natural compass. Ants can detect this pattern and adjust their direction based on the orientation of the light. In this study, foragers responded

Signals from within. How the heart talks to the brain

Signals from within. How the heart talks to the brain

Interoception is the mind's ability to sense its internal state. While traditionally studied as a whole-body experience, researchers now suggest breaking it into specialized domains. One key domain, cardioception, focuses on how the brain perceives signals from the heart. This involves unique neural pathways and specialized structures that

Space week day 6: Faster than light makes you younger, but otherwise spaceflight ages us

Time dilation, a concept of Einstein's, occurs when an object moves close to the speed of light. For astronauts traveling at near-light speeds, time would pass more slowly for them relative to people on Earth. In theory, astronauts could age slower compared to individuals on Earth if they

Space week day 5: A bit more gravity for my brain, please

Microgravity is the condition when astronauts experience weightlessness in space. While orbiting the Earth, astronauts aboard the International Space Station experience just that. A lack of gravitational force is known to affect multiple physiological functions of astronauts, particularly damage to the central nervous system. Notably, it affects the brain, where

Space week day 4: Sleeping with altered circadian rhythm, nights and day turmoil and no gravity

Astronauts rely heavily on mental sharpness and emotional stability to perform their duties during space missions. And adequate sleep is critical for maintaining physical and behavioral health. Extensive evidence indicates that regular nightly sleep of 7–8 hours is sufficient to maintain health. But despite having scheduled sleep times of

Space week day 3: Is there gender equality on Mars?

Space week day 3: Is there gender equality on Mars?

Space travel presents a range of challenges to the human brain, and sex and gender do play roles in how individuals respond to cosmic voyages. The human brain (on Earth) shows key differences between men and women in structure, neuron development, and chemical pathways, which may affect how astronauts cope
