What are enzymes? Enzymes are substances capable of accelerating a variety of processes in our body. You can compare their effect with catalysts (they also catalyze a reaction). So, almost every process in our body requires the participation of a specific enzyme. The most famous example of an enzyme is lactase; it breaks down lactose, which is found in milk👇🏻 Some people have a congenital lack of lactase and cannot digest dairy products.

Cell membrane That’s the structure which separates the cell from the outside environment. The task of the membrane is not only to maintain its integrity, but also to transport substances into and out of the cell.

Typical Math Class In Chinese School A teacher uses an interactive whiteboard. The functionality of interactive whiteboards makes it easy to show tutorial content for educational institutions and successfully perform business presentations. In essence, an interactive whiteboard is a large tablet computer.

Robo-Dogs If you think robo-dogs are clumsy and slow, here's a study where scientists have trained an algorithm for certain actions, using a neural network and without any human control. Such a system allows the robo-dog to autonomously adjust different movement skills in a variety of conditions (soft surface, slippery, etc.). Also, the robot itself can get up after falling on its back.

Canister therapy Specially trained dogs can positively impact the treatment of depression, insomnia, eating disorders, neurosis, recovery from trauma, strokes, stress disorders, correction of cerebral palsy, Down syndrome, Alzheimer's disease various types of dementias, and autism spectrum disorders (ASD).

Methane Bubbles in the Baikal Ice Baikal is not only the oldest and deepest lake in the world, containing one-fifth of the world's freshwater reserves, but also a huge methane reservoir.

Robotica • Giuseppe Lo Schiavo: "After MONTHS of production and sleepless nights ROBOTICA, my second NFT, is finally released today! I hope you all enjoy it."

Curious development for the home 💡 CleanseBot It's a tiny cleaning robot that disinfects your bed from various germs and bacteria.

American students created a flying drone with propellers based on Leonardo da Vinci's sketches Students managed to accomplish what the great creator failed to do: they made a drone with a propeller design make several short flights. A team of University of Maryland engineers has created the Crimson Spin drone with Archimedean propellers, CNet reports. They were developed in ancient times to move water. Leonardo da Vinci came up with a different use for the propeller and in the XV century proposed the concept of a flying machine.

Protein pumps They carry out the transport of substances across the cell membrane, using energy in the process. That’s why this process is called active transport

MRI of the heart over time Our heart, which is only slightly larger than a fist, performs a titanic job during the course of a lifetime; It sends 5 to 30 liters of blood per minute into the arteries and contracts approximately 100,000 times a day, 36 million times a year, 2.5 billion times in 70 years of life. In terms of capacity and duration of operation without "overhaul," the heart surpasses all mechanisms invented by man.

Dermographism (artificial urticaria) A physiological phenomenon consisting of a change in the color of the skin at the site of mild irritation.

Angular cubic prism A beam of light entering a mirrored reflective prism always exits along a parallel path.

Agora Gallery is pleased to announce a solo exhibition by BREAKFAST, a New York-based robotic kinetic studio led by artists Andrew Zolty and Mattias Gunneras. The exhibition features highly interactive sculptures commenting on topics of environmental and social re evance.

Cancer cell division👆🏻 Cancer is a disease starting with a mutation, when a cell in the body begins to divide uncontrollably.

Swanky fluorite with quartz 💎CaF2 The coloration is caused by defects in the crystal structure, which is highly responsive to radiation exposure and heating.

How airplanes fly If flying paper airplanes through smoke, we may notice not so great contrasts with their big brothers furrowing the expanse of the sky above our heads✈️ All airplanes fly due to pressure gaps between the upper and lower surfaces of the wing with higher air pressure from below the wing. Therefore, when the higher pressure air from below the wing "flows" over the edge of the wing to the upper wing surface, an air "whirlpool" or vortex occurs. Hence why the vortices swirl upward and toward the center of the airplane, and also why airplanes feature little wings or winglets at the ends of the wings. They increase the effective wingspan by reducing the drag created by the vortex coming off the end of the wing and, as a result, increase the lift at the end of the wing.

☝🏻 That’s right to breathe through your nose, not mouth Breathing through the nose heats the air and cleanses it of harmful germs, which is not the case when breathing through the mouth. The mouth lets the cold and polluted air go straight to your lungs.
