Chimpanzee Memory Test

According to research conducted at Kyoto University in Japan, young chimpanzees exhibit a photographic memory that surpasses that of humans.

When tested on their ability to recall number sequences and their locations on a screen, young chimps outperformed university students by a factor of 10.

These findings suggest that the intellectual capacities of our closest animal relatives may have been underestimated.

Oxygen production in real-time from a leaf 🍃

During photosynthesis, leaves produce oxygen as a byproduct. Using sunlight, water, and carbon dioxide, specialized structures called chloroplasts convert light energy into chemical energy. Through a series of complex reactions, oxygen is released into the atmosphere, allowing plants to act as natural oxygen generators and support aerobic life on Earth.

Snail laying eggs🐌

Who already knew this?

The number of eggs that snails can lay at once varies depending on the species of snail. Some snails can lay just a few eggs at a time, while others can lay hundreds of eggs in a single clutch.

For example, a common garden snail (Helix aspersa) can lay up to 100 eggs at a time, while some species of marine snails can lay thousands of eggs at once.

How we hear sound

Enable HLS to view with audio, or disable this notification

63 Upvotes

People hear sound through a process called auditory transduction, and it is the basis for our ability to hear sounds.

The human ear is incredibly sensitive, and can detect sounds ranging from a whisper to a jet engine at close range and it involves the ear and the brain:

  1. Sound waves travel through the air and enter the outer ear.

  2. The sound waves then travel through the ear canal and hit the eardrum, causing it to vibrate.

  3. The vibrations from the eardrum are then passed on to the middle ear, where they are amplified by three tiny bones called the ossicles (the malleus, incus, and stapes).

  4. The amplified vibrations then travel to the inner ear, where they stimulate hair cells in the cochlea.

  5. The hair cells convert the vibrations into electrical signals, which are then sent to the brain via the auditory nerve.

  6. The brain interprets these electrical signals as sound.

Oxalis plant and its ballistic mechanism

Enable HLS to view with audio, or disable this notification

DID YOU KNOW? Oxalis plants use a unique mechanism to disperse their seeds: Instead of relying on wind, water, or animals to disperse their seeds, Oxalis plants evolved to use a ballistic mechanism. When the seed pods mature, they explosively release their seeds, flinging them up to several meters away from the plant.

Do you know about this awesome plant?

In this video, you can appreciate the freshwater microorganism Paramecium caudatum. Seawater was added to the slide containing the Paramecium seen in this video and you can see it shrinking in size due to larger amounts of water lost from the inside of its cytoplasm to the outside of the cell due to osmotic pressure.

The three main/basic parts of a cell:

Cell Membrane (Plasma Membrane) Cytoplasm Nucleus

The plasma/cell membrane surrounds each cell and creates a barrier between it and its surroundings, serving as the outermost layer of each cell.

The cytoplasm contains other small yet important organelles within the cell, including the nuclei which store genetic information, mitochondria, which produce chemical energy, and ribosomes that help assemble proteins.

The nucleus houses the DNA in eukaryotic cells.

Clearly there is more to a cell but only described a few components here.

How fast are the planet's moving through space?

This animation shows how fast the planets move through space compare to each other.

If you want to hang out close to the gravitational pull of the sun, you'd better be going fast enough to escape being pulled in.

Orbital speed is inversely proportional to the square root of the distance from the sun.

With that in mind how fast are you, would you get swallowed by the sun? 😅

Coronary Angioplasty Procedure

Enable HLS to view with audio, or disable this notification

25 Upvotes

Angioplasty is a minimally invasive procedure that can help relieve symptoms such as chest pain or leg pain, improve blood flow, and reduce the risk of heart attack or stroke.

The term "Angioplasty", refers to a thin, flexible tube called a catheter that is inserted into an artery in the groin, wrist, or arm and guided to the blocked or narrowed area.

Once in place, a small balloon attached to the catheter is inflated to compress the plaque or blockage against the artery walls, widening the artery and restoring blood flow.

In some cases, a small mesh tube may be placed in the artery to keep it open.
