Neuron vs viruses vs bacteria. Microorganisms size comparison:

At the smallest end, viruses reign as the tiniest entities, mere nanometers in size, carrying genetic information within a protein coat.

Slightly larger, bacteria emerge, ranging from 0.5 to 5 micrometers, displaying diverse shapes and functions, from beneficial symbionts to potential pathogens.

Cells, the building blocks of life, often measure tens to hundreds of micrometers, encompassing organelles that facilitate complex processes.

And then there are tardigrades, often dubbed “water bears,“ small yet hardy creatures measuring around 0.1 to 1.5 millimeters, displaying resilience in extreme environments.

How do you hear sounds? From your ears to brain cells:

1. Sound waves enter the outer ear and travel through the ear canal, which leads to the eardrum.

2. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear.

3. The bones in the middle ear amplify the sound vibrations and send them to the cochlea, a snail-shaped structure filled with fluid.

4. Once the vibrations cause the fluid inside the cochlea to ripple, they make hair cells move up and down. When that happens, chemicals rush into the cells, creating an electrical signal.

5. The auditory nerve carries this electrical signal to the brain, which turns it into a sound that we recognize.

Human body from the inside: 👀

Here are some of the main systems in our body:

Nervous System: This complex system is responsible for transmitting signals between different parts of the body and the brain. It controls voluntary and involuntary actions and enables sensory perception.

Circulatory System: This system includes the heart, blood vessels, and blood. It transports oxygen, nutrients, hormones, and waste products throughout your body.

Respiratory System: Comprising the lungs and airways, the respiratory system facilitates the exchange of oxygen and carbon dioxide, allowing us to breathe and provide oxygen to the bloodstream.

Digestive System: It processes food, extracts nutrients, and eliminates waste. Organs like the stomach, intestines, liver, and pancreas play vital roles in this system.

Endocrine System: The endocrine system involves a network of glands that release hormones to regulate various bodily functions and maintain homeostasis.

Muscular System: Muscles enable movement, support the body's structure, and facilitate essential functions like breathing, digestion, and blood circulation.

Skeletal System: Composed of bones, cartilage, and ligaments, the skeletal system provides support, protects vital organs, and allows movement.

This video inspired me this week ... in #agriculture, various processes can be extremely developed and thus made faster, more #efficient and #sustainable!!

What other potentials exist in agriculture?

✔️ 𝗣𝗿𝗲𝗰𝗶𝘀𝗶𝗼𝗻 𝗙𝗮𝗿𝗺𝗶𝗻𝗴: Farmers can use GPS-guided tractors and planting equipment to precisely place seeds in optimal locations, reducing seed waste and improving crop yield.

✔️ 𝗖𝗿𝗼𝗽 𝗠𝗼𝗻𝗶𝘁𝗼𝗿𝗶𝗻𝗴: #AI-drones equipped with multispectral cameras can capture high-resolution images of crops, allowing farmers to detect early signs of diseases or pests and take targeted action.

✔️ 𝗦𝘂𝘀𝘁𝗮𝗶𝗻𝗮𝗯𝗹𝗲 𝗣𝗲𝘀𝘁 𝗠𝗮𝗻𝗮𝗴𝗲𝗺𝗲𝗻𝘁: AI-powered cameras can identify specific pests like aphids in real-time, enabling the use of targeted and less harmful pest control methods.

✔️ 𝗦𝘂𝗽𝗽𝗹𝘆 𝗖𝗵𝗮𝗶𝗻 𝗢𝗽𝘁𝗶𝗺𝗶𝘇𝗮𝘁𝗶𝗼𝗻: #Blockchain technology is used to trace the origin and journey of specific food products, ensuring food safety and reducing food waste.

✔️ 𝗦𝘂𝘀𝘁𝗮𝗶𝗻𝗮𝗯𝗹𝗲 𝗣𝗮𝗰𝗸𝗮𝗴𝗶𝗻𝗴: Bio-based and compostable packaging materials can extend the shelf life of fresh produce while reducing plastic waste.

✔️ 𝗖𝗹𝗶𝗺𝗮𝘁𝗲 𝗣𝗿𝗲𝗱𝗶𝗰𝘁𝗶𝗼𝗻: Advanced #climate models can provide farmers with forecasts of extreme weather events, allowing them to prepare and adapt to changing conditions.

𝗛𝗼𝘄 𝗰𝗮𝗻 𝘄𝗲 𝗳𝘂𝗿𝘁𝗵𝗲𝗿 𝗼𝗽𝘁𝗶𝗺𝗶𝘇𝗲 𝗼𝘂𝗿 𝗮𝗴𝗿𝗶𝗰𝘂𝗹𝘁𝘂𝗿𝗲?

New AI technology is being deployed to detect road defects and enhance road safety.

Laser-equipped patrol cars will scan for potholes and tiny cracks as small as 1mm. With a highly accurate virtual map of Dubai's roads, this innovative system is set to improve the transport network and make roads safer for everyone.
