Orange zest is full of juice and essential oils, and these oils burn. Looks stunning!

Another Way to Eat Less It seems that scientists have invented the most effective device for weight loss, called DentalSlim Diet Control, which literally closes a person's mouth! The device consists of several metal clips with magnets. It is placed on the upper and lower jaw teeth by the dentist. Once the device is triggered, the jaws instantly snap shut, closing the mouth, which can only open 2 millimeters to breathe, speak, drink water, and eat food in liquid form only. Research participants using this device lost an average of 6.36 kg in two weeks!

What's the magic? In order to better examine the effects of pollutants on fish, Taiwanese scientists inserted jellyfish genes into the DNA of koi carps, resulting in these luminous aquarium fish!

How do Water Ripples Appear? The ripples you see on the surface of seas and lakes arise from both the upward force of internal water pressure and the surface tension force. Both forces alternate and lots of ripples form on the water. This resembles the sound wave that occurs in the string of a musical instrument as it's alternately stretched and squeezed.

DNA in the Air Scientists have come up with a way of detecting the tiniest traces of DNA in the air. The discovery, for example, enables studying wild animals, which normally live in hard-to-reach places, deserts, rainforests, caves, etc. Otherwise, it could transform forensic investigations at crime scenes, or on-site processes (rubble, etc.). This is no longer just a theory⚡ The DNA collection technique was tested in a zoo by installing sensitive filters attached to vacuum pumps at 20 points throughout the facility. The equipment appeared so sensitive that it picked up DNA from pets living in the zoo's neighborhood and animals that were food for predators. Though the technique is in the early stages of study, it shows impressive results. No less epic results with human DNA. Exciting prospects are coming up in forensics...

Archimedes' law is one of the laws of statics of liquids (hydrostatics) and gases (aerostatics): the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially, is equal to the weight of the fluid that the body displaces

Such a beauty appears if you water the screw with ferromagnetic liquid (it is strongly polarizing in the presence of a magnetic field liquid, which contains ferromagnetic nanoparticles).

Barium Sulfate Used In LEGO Parts If a child swallows a LEGO part, it will be visible on an X-ray due to this compound. However, sulfate was abandoned in 1996 as it made the plastic brittle.

Here is a collection of real elements from the Mendeleev’s Periodic Table! Wonder about how airtight this thing is... After all, it contains elements that can be harmful to a person.

Static Discharge Imagine the situation; someone invites you to visit. You come to the door on time, wipe your feet on the mat thoroughly, then touch the brass door handle... and that's when you feel a slight impact. It's a static discharge. Why does this happen? After you had wiped your feet on the mat, your body received a negative electrical charge. Then you touched a negatively charged hand to a positively charged metal object (a door handle in our case) and the electrons transferred from your hand to that object. Such an instantaneous transfer of electrons is called a static discharge. It was precisely at the moment you felt a slight electric shock.

CyberDog: Xiaomi First Robotic Dog Does your dog know how to do a backflip? 🤖 Well, Xiaomi dog can. Jetson Xavier NX module from Nvidia, containing 384 CUDA cores, 48 tensor cores, six Carmel processors and two specialized deep learning cores, became the computing center of the robot. The module collects and processes information from 11 sensors. It uses specially designed Xiaomi servos to move, enabling it not only to walk, but also to do backflips and other tricks. In fact, the machine moves at 3.2 meters per second and weighs 3 kilograms. Xiaomi reports that the robot can follow its owner like a real dog. The device also recognizes faces. By the way, the CyberDog can be controlled by voice or through a smartphone app. What do you think, whether the robot is capable of fully replacing a real animal?
