There are three types of cone cells in the retina that are called L-cones (sensitive to red light), M-cones (sensitive to green light), and S-cones (sensitive to blue light). The coordinated response of cone cells to visible ...
The cellular forms of natural materials are the inspiration behind a new lightweight, 3D printed smart architected material developed by an international team of engineers.
Animals have three main strategies to survive the freezing temperatures of winter: migrating, remaining in place and resisting the cold, and reducing body temperature and metabolic rate in a state called torpor.
To get to the places where they are needed, immune cells not only squeeze through tiny pores. They even overcome wall-like barriers of tightly packed cells. Researchers at the Institute of Science and Technology Austria (ISTA) ...
It's been 50 years since humans first walked on the moon. Since then, astronauts have primarily explored low Earth orbit. Now that NASA is preparing to return to the moon, experts are reevaluating the practicality of the ...
The search for extraterrestrial life and exploration of "another Earth" is an eternal theme for humans and inspires generations of planetary scientists. It not only improves our understanding of the formation and evolution ...
The world must halt its increase in greenhouse gases within the next three years, cut them by 43% in the next seven, and eliminate them entirely by 2050 to avoid catastrophic and irreversible climate change impacts this century, ...
