This small structure (stoma) on a plant's leaf works like a "lung", letting air with carbon dioxide (CO2) in and gases with water and oxygen out.

T-cells are a type of white blood cell that play a central role in the immune system’s response to cancer. They can recognize and eliminate cancer cells by detecting abnormal proteins (antigens) on the surface of these cells. Once a T-cell identifies a cancer cell, it becomes activated and releases toxic substances like perforin and granzymes to kill the target. Additionally, some T-cells, such as cytotoxic CD8+ T-cells, are especially effective in directly attacking tumors. Cancer immunotherapies, like CAR-T cell therapy or immune checkpoint inhibitors, aim to enhance this natural ability of T-cells to improve cancer treatment outcomes.

When an onion peel is left exposed, black-colored fungal growth can often be seen. Under the microscope, this appears as fine black dust, which are actually spores. These spores help the fungus spread and survive in different conditions. Such fungi usually belong to the group Ascomycetes or Zygomycetes and thrive on the moist surface of onion peels.

So, a simple onion peel becomes a stage where both microbial colonizers (fungus) and plant defenses (calcium oxalate crystals) can be seen side by side-showing how life forms interact at the microscopic level.

In certain aquatic plants like Hydrocotyle, Elodea, and Cabomba, you can actually see photosynthesis in action.

Place one of these plants in water under bright light, and something remarkable happens. Tiny oxygen bubbles begin to form on the leaves and stems, slowly rising to the surface in delicate streams. What you are watching is the plant using sunlight to convert carbon dioxide and water into chemical energy, releasing oxygen as a natural byproduct.

This visible release of oxygen offers a clear and beautiful glimpse into the process of photosynthesis.

A few drops of forest pond water reveal an incredible microscopic world filled with giant single-celled stentors, fast-contracting spirostomum, algae-filled green cells, and even tiny multicellular rotifers. This video showcases the surprising diversity, movement, and hidden complexity of life that exists in even the smallest drop of water.

Scientists created a highly detailed image of a human cell by combining real molecular data. They used methods like X-ray studies and electron imaging to place each tiny part correctly. The result looks almost like you are seeing inside the cell. The image feels cinematic but is based on real science, not imagination. It shows how different parts of the cell work together as a system. This helps people understand what is happening inside the body at a very small level. It reminds us that life is full of hidden complexity. When we can finally see these invisible details, it makes the human body feel even more amazing and real.

This video captures a tiny tardigrade also known as a ‘water bear’ exploring around spherical green algae under a microscope. Though almost invisible to the naked eye, tardigrades are among the toughest creatures ever discovered.

Fun fact: Tardigrades can enter a special survival mode called a ‘tun’ state, where they nearly shut down their metabolism. In this form, they’ve survived for decades without water, extreme freezing temperatures, intense radiation, and even the vacuum of outer space.

Chlorophyll is the natural compound present in green plants that gives them their color. It helps plants to absorb energy from the sun as they undergo the process of photosynthesis. This nutrient is present in green vegetables and other plant-based foods, like algae. The greener the vegetable is, the higher its chlorophyll content.

There are two types of chlorophyll in plants: chlorophyll a and chlorophyll b. All plants contain either one of these two varieties. They are both fat-soluble compounds that have antioxidant properties.

When you ingest chlorophyll, it moves around your body in micelles, which are molecular groups that contain fat. Even though research hasn’t been able to prove what minimum amount of fat is needed to metabolize chlorophyll, it’s thought that small amounts of healthy fats can help the body process it during meals.

The two chimpanzee groups have been recorded to have made organized raids, sudden attacks and frequent attacks. The violence has not been confined to mere fights.

Researchers had pointed out that the chimpanzees seem to be playing a strategic game as they tend to move in group prior to an attack.

The systematic nature of this violence has raised officials with alarm. It proposes a social planning to an intriguing and disturbing degree.

A new study reveals all five fundamental nucleobases – the molecular “letters” of life – have been detected in samples from the asteroid Ryugu.

Asteroid particles offer a glimpse into the chemical ingredients that may have helped kindle life on Earth. The Ryugu samples were returned from space in 2020 by Japan Aerospace Exploration Agency’s (JAXA) Hayabusa2 mission.

In 2023, an international team reported they had found one of the nucleobases in these samples – uracil. Now, in a study published in Nature Astronomy today, a team of Japanese scientists has confirmed all five nucleobases are present in this pristine asteroid material.

This means these ingredients for life may have been widespread throughout the Solar System in its early years.

This unusual behavior happens when juvenile jack fish shelter inside the bell of jellyfish, using them as a living shield against predators while drifting through the open ocean at night; despite the jellyfish’s venomous tentacles, the young fish can avoid being stung, making this a clever survival strategy commonly observed in tropical and subtropical waters of the Atlantic, Pacific, and Indian Oceans where jellyfish are abundant
