The Weissenberg Effect An effect that is typical of some non-Newtonian fluids, such as liquid polymer solutions. Instead of being thrown outward, the chain of polymers is wound around the rod.

Natural calcium carbonate — CaCO3😍 Calcium carbonate is an inorganic chemical compound, a salt of carbonic acid and calcium. It is used as a white food coloring E170. As the base of chalk, it is used for writing on blackboards. Also, it’s utilized at home for whitewashing ceilings, painting tree trunks, for alkalizing soil in gardening.

The Rehbinder effect In physics, it is the reduction in the hardness and ductility of a material, particularly metals, by a surfactant film The following conditions are needed for the Rehbinder effect to occur: - Contact of a solid body with a liquid medium - The presence of tensile stresses

Leadwood A cleaned plate of galvanized tin is immersed in a solution consisting of lead acetate and water. The surface is covered with small, dark gray crystals of lead with a metallic luster, fused together.

Perfect match Jingdiao demonstrates the result of the accuracy of their metalworking machines.

👆🏻 How white blood cells move through the blood in search of pathogens for immune protection. Normally, our immune system is incredibly strong and can protect us from so many viruses and bacteria

It happens in our bodies on a second by second basis. The protective cell, the phagocyte, absorbs and digests the bacteria alive.

Japanese Model T robot's first sample Remote VR control of robots could become an alternative to daily commutes and even labor migration to other countries. Japanese startup Telexistence showed how a Model T bot could be used to work remotely in a grocery store. A human operator controls the robot from home using a VR helmet and controllers.

Dispersion of Light This is a set of phenomena caused by the dependence of the absolute index of refraction of matter on the frequency (or wavelength) of light (frequency dispersion), or, similarly, the dependence of the phase velocity of light in matter on the frequency (or wavelength).

Ascorbic acid in polarized light 🔬 If you wish to live longer and look younger in the meantime. Besides all its health benefits, ascorbic acid (or vitamin C) also promotes the production of collagen, thereby slowing down the aging process of the skin.

Chimpanzees Have Better Visual Memory Than Humans Thus, it's quite easy to teach it to count to 10 and to press buttons on the phone, even for the likes (that is, without any real material reward). Doesn't it remind you of anyone? After all, memory is an amazing thing, capable of incredible deeds. It's like a Ferrari. You can race it, win races, if you train properly. Yet, unfortunately, most people have their Ferrari just sitting idle in the garage, sometimes just going out for bread. Do you remember what your loved ones wore yesterday and what the license plate number of the neighboring car in the parking lot where you leave your car? Many, by the way, do not even remember the license plate number of their car!

Melanite (black andradite garnet) 🧪Ca3Fe2Si3O12 Melanite is a kind of andradite garnet rich in titanium impurities. For many people it is a "revelation" that garnets are not only red. But just andradite can be green, yellow, brown, and even black.

T cell killers destroy a cancer cell T-killers, or cytotoxic T lymphocytes, are white blood cells that specialize in attacking viruses and tumor cells. There are about five million of them in one teaspoon of blood!

Scientists claim we should take at least three weeks off a year Here's a fresh study about stress and vacations. Studied 1,222 male businessmen over 40 years, almost everyone had at least one risk of cardiovascular disease. One group received regular lifestyle advice, if risk factors persisted, pharmacotherapy; the control group had routine checkups. Initially, the risk in the control group decreased by 46%. However, 15 years later, it was found that the mortality rate was higher in the control group than in those with reduced risks! After comparing all other lifestyle factors, the scientists found that those who worked more and rested less were more likely to die. ☝🏻 Resting less than three weeks a year increased mortality by 37%.

Physical Telepresence 💡Daniel Leithinger, Sean Follmer, Alex Olwal, Hiroshi Ishi "We propose a new approach to physical telepresence, based on shared workspaces with the ability to capture and remotely render the shapes of people and objects. In this paper, we describe the concept of shape transmission, and propose interaction techniques to manipulate remote physical objects and physical renderings of shared digital content. We investigate, how the representation of user's body parts can be altered to amplify their capabilities for teleoperation and describe our finding of building and testing prototype physical telepresence workspaces. A preliminary evaluation found users were able to manipulate simple objects remotely, and found many different techniques for manipulation that highlight the expressive nature of our system."

Germans are about to start breeding genetically-modified pigs for heart transplantation into humans The first generation of animals will be born this year, and by 2025 the organs of such pigs are planned to be used in clinical trials. The idea sparked a heated debate in society: supporters consider it a salvation for terminally ill people, while opponents accuse it of being unethical with respect to animals.

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.

Anodizing 🌈 The process of creating an oxide film on the surface of certain metals and alloys by their anodic polarization in a conductive medium. Various types of anodizing exist, including electrochemical one - the creation of an oxide coating on the surface of different metals (Al, Mg, Ti, Ta, Zr, Hf, etc.) and alloys (aluminum, magnesium, titanium) in an electrolyte medium, aqueous or non-aqueous.
