Protect the snows of Kilimanjaro

06.05.2004

The snows of Kilimanjaro are melting. Now their area compared with 1912 has decreased by more than 80 percent and amounted to only 2,5 square kilometers.

English climatologist J. Nisbett proposes to cover the remaining snow cap of the mountain with a white polymer film to stop the melting. It will need 50-100 tons. But other experts are skeptical about this proposal and believe that the film can, on the contrary, accelerate the melting, acting as a cover for the greenhouse.

It's not the heat of the sun, they say, but the fact that the forests that grew on the slopes of this extinct volcano have been cut down. From this, the humidity of the air surrounding Kilimanjaro decreased, and the growth of the ice cover stopped.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Apple phones will be able to fall like cats 04.04.2013

The US Patent and Trademark Office (USPTO) has published a patent application from Apple that describes ways to minimize damage when a phone is dropped, according to the Apple Insider Blog. Apple proposes to teach the phone's system to detect when the device is in free fall. For this, built-in sensors can be used - a gyroscope, an accelerometer, GPS, and even a camera. If a fall condition is detected, the system will take action to mitigate the damage.

One of these measures is the rotation of the device in the air. This will "ground" the phone on its least vulnerable side. In this case, the device will not touch the ground with the screen, but, for example, with the side panel. A gas cylinder or a center of gravity shift mechanism can be used to rotate the apparatus. Cats have similar abilities: when falling from a height, they reflexively turn their backs up and land on their paws.

Other measures described by Apple include "wings" that slide out of the body of the device and clips on the headphone and charging cables. "Wings" allow you to slow down the fall of the phone. Clamps prevent the cable from falling out of the socket: if the device falls, it will hang on the wire.

The patent application says that the development can be used in the iPhone, as well as in other electronic devices - smartphones, tablets, players, cameras, and so on. Note that the technologies described in patent applications are not always implemented in life.

Other companies are also developing fall protection systems for mobile devices. So, at the end of December 2012, the head of Amazon Jeff Bezos (Jeff Bezos) received a patent for "air cushions" for the phone. According to the principle of operation, they are similar to the pillows that are used in cars.
