Well, how can you resist?

That is why it is impossible to resist the gaze of dogs. One of the discoveries of the scientific event Experimental Biology 2022 was the study of the guys from Pittsburgh. They studied the evolution of dogs, and came to the conclusion that, unlike wolves, evolution added special muscles to the face of dogs to create that very kind dog look. So, dogs were able to establish a productive relationship with people.

Why 100% humidity is not water?

Because we are talking about the relative humidity of the air. When the air humidity is 100%, this means that the maximum possible amount of water vapor is in the air and the air cannot take more. In other words, the evaporation of water under these conditions is impossible. The lower the relative humidity of the air (that is, not 100%, but, say, 23%), the more water can pass into steam and the higher the rate of evaporation.

Hand made of "liquid metal"

American scientists from Binghamton University have created a hand from "liquid metal" like the Terminator! The product consists of a Fields alloy, which includes bismuth, indium and tin, and a rubber-like elastomer frame has been stretched over it. Thanks to these tricks, the structure can be deformed as you like, and after heating it returns to its original state.

The most expensive fountain

Danger of marijuana for pets

Pets have become even more likely to be poisoned with cannabis after its legalization in Canada. This conclusion was reached by a team of researchers after analyzing the results of a survey of 251 veterinarians from Canada and the United States.

Although most of the affected individuals were quickly cured, sixteen deaths were reported by veterinarians.

Cementless eco-concrete

In Canada, they came up with cementless eco-concrete from waste. The new material is 30% stronger than the classic counterpart. The manufacturer uses steel slag and carbon dioxide from the surrounding air instead of cement. As a result of their contact, calcium carbonates are formed. The pilot project provides for the production of 450 tons of concrete per day, which is 25,000 bricks. With such volumes, the new technology will allow capturing about 20 tons of carbon dioxide per day.

The Large Hadron Collider is up and running again

The world's most powerful particle accelerator, the Large Hadron Collider, has returned to work after a three-year hiatus for repairs and upgrades and has begun its third run. Today, beams of protons at an energy of 450 gigaelectronvolts began to circulate in the LHC ring for the first time. In the future, scientists plan to conduct experiments at collision energies of 13.6 teraelectronvolts.

Smart lenses

The timing of the appearance of smart lenses is predicted. The authors of the material noted that many forecasts for the 2040s say that smart lenses will appear on the market of the future. With their help, people will be able to receive information and collect data on medical indicators. Thus, experts predicted the approximate timing of the appearance of smart lenses on the market - the authors believe that this will happen no earlier than in 20 years. The main players in the smart optics market will be Google, Samsung and Sony

James Webb telescope

The James Webb telescope has become one of the coldest objects in space. The temperature of the main MIRI instrument reached -266.75 degrees Celsius. This is only 6 degrees warmer than absolute zero, at which the molecules stop moving. The telescope is almost ready to start shooting deep-sky objects
