What are taste buds? And how does our sense of taste work? Well, first of all, your mouth isn’t alone on this project – it also needs the nose (specifically, your sense of smell) to taste all the food you eat. Together, the combo consists of 80% smell and only 20% of taste itself! Meaning, the journey doesn’t start in the mouth. It all starts when you just walk into a room with food. Every time you breathe in, you inhale everything in the air. And in our case, it includes small particles of pizza floating in the air. Yes, there are millions of microscopic pizzas flying around! But why does hot food smell more? And why does airplane food tastes weird? How do smells information influence emotions and memories? Let's find out!

In August 2018, a UK woman was sailing on the Adriatic Sea. Seems like nothing out of the ordinary, just the perfect summer vacation out on the open water! The Norwegian Star cruise liner was heading to Venice, Italy after departing from Vargarola, Croatia. The woman was on the 7th deck, when, right before midnight, she fell off the back of the ship!

The liner also contacted the authorities, and they dispatched a patrol ship, a plane, and 2 rescue boats to look for the woman.

When you hear a police siren blaring around the corner, you’re already expecting to see a sedan painted in certain colors rushing past you. But have you ever wondered why exactly police cars are painted in colors they use? In fact, there are plenty of reasons for that in any given country. Let’s take the USA and Canada for example. When first North American police cars appeared in the early 1900s, pretty much all automobiles were painted black, and law enforcers weren’t any exception. Later, most authorities across the US thought it prudent to make police cars easily recognizable to the public. And so they worked out a color palette that would be both symbolic and affordable for the budget.

Gravity is a powerful force that affects everything we do. Physicists are fascinated by its mysteries and are on a quest to understand it. Isaac Newton first explained gravity, describing how objects are attracted to each other based on their mass and distance. Albert Einstein's theory of general relativity took gravity to a new level, explaining it as the curvature of space-time caused by massive objects. While we have a good grasp of gravity's behavior in certain situations, like planetary orbits, it becomes more complex on smaller and larger scales, leaving scientists with unanswered

Space exploration gives us two options: a lengthy journey to another solar system or the more feasible option of Mars. A study suggests that all-female crews could offer advantages, as female astronauts require less water, energy, and food during missions.

These findings highlight the operational benefits and cost savings associated with all-female crews in future space exploration.

Have you ever wondered why passenger planes don't have parachutes? Well, parachutes large enough to safely land an entire plane would be incredibly heavy, and that extra weight would reduce the number of seats available for passengers. In the event of an emergency, panic would quickly set in among passengers, making it unlikely that they would be able to properly use their parachutes. It would be impractical and potentially dangerous to have untrained individuals attempting parachute landings during an emergency. Instead of individual parachutes, some lightweight aircraft have whole-plane parachutes installed.

Twelve volunteers are participating in an experiment where they stay in bed for two months to simulate the effects of space travel on muscles. In microgravity, muscles weaken and shrink due to a lack of exercise and reduced protein production. Scientists are researching ways to counteract muscle loss, including exercise routines and hormone treatments. The study found that exercise improves muscle health and organization, while testosterone injections can further enhance muscle growth. The findings could help develop personalized programs for astronauts and improve muscle treatments for the elderly and patients on Earth.
