Engineers have created a cooling device that does not require electricity to operate. An article about this was published in Cell Reports Physical Science.

In the United States created a refrigerator for third world countries that does not require food

The device was invented by scientists at the Massachusetts Institute of Technology. Outwardly, it looks like a thick pizza box wrapped in foil. The “box” is made of three layers of material. At the bottom is a reflective foil, in the middle is a porous material based on hydrogel with a large proportion of water, on top is airgel, a very light material, 99% air. When heated, water evaporates from the hydrogel, cooling it, and enters the airgel, where it is additionally cooled by infrared radiation. In addition, the airgel cap serves as an insulator and reflects light as well as the bottom layer.

The device must be placed above what needs to be cooled. It can reduce the temperature of an object by 10 degrees compared to the environment. According to the developers, the system is able to increase the shelf life of food products by 40% in conditions of high humidity, or three times if it is hot and dry outside. First of all, such a refrigerator is in demand in hot third world countries, where there are problems with electricity.

For iPhone 15, Apple will purchase the latest Sony sensors, which have no analogues on the market

For iPhone 15 Apple will purchase the latest Sony sensors

Sony will supply its state-of-the-art image sensors to Apple, which will be used in the iPhone 15 line of smartphones.

For iPhone 15, Apple will purchase the latest Sony sensors, which have no analogues on the market

The new Sony Semiconductor Solutions sensor has roughly doubled the saturation signal per pixel compared to conventional image sensors. This matches the description of the new technology that Sony talked about last year.

This is the industry’s first multi-layer CMOS sensor. While the photodiodes and pixel transistors of conventional CMOS sensors are formed in the same layer, they are in different layers in the new sensor. This allows you to expand the dynamic range, increase the photosensitivity and reduce the noise level.

Apparently, this technology has not yet found application in any of Sony’s sensors. Whether Apple will be the first to receive such sensors is unknown. It is also unclear whether they will be used in all iPhone 15 or only in older models. Given the trends of recent years, as well as all the rumors about Apple’s intention to separate younger and older iPhones more strongly, it is likely that only older models will get new sensors, or even exclusively iPhone 15 Ultra.

Telegram will receive support for paid phone numbers but it

In the latest beta version of the Telegram mobile client for Android, there was a mention of anonymous virtual phone numbers that can be bought. They will be on sale on the Fragment site, but the exact launch date has not yet been given.

These numbers will begin with the code +888, and it will be impossible to call them. They are designed specifically to work with Telegram and are used to receive confirmation codes. It is not yet reported whether there will be rooms with a different code.

The price, terms of sale or other data about the system are also not reported. However, it is possible that the scheme will work the same way as with nicknames that are already sold on Fragment.

Note that the site has already found the most expensive nickname – @news. They paid $1.76 million for it. The name of the buyer is not disclosed.

ONBTC will develop, analyze and evaluate plans, programs and projects related to Bitcoin and aimed at the economic development of El Salvador. If necessary, the division will also be able to cooperate with other countries in matters related to the first cryptocurrency.

Among the main functions of the organization is the conceptualization and provision of information related to Bitcoin, blockchain and cryptocurrencies in El Salvador to “the media and any interested parties.”

All government agencies are required to assist the National Bitcoin Office in the performance of its functions. The director of ONBTC will be appointed by the head of state.

Earlier, the country’s authorities began considering a bill designed to introduce into the legal field the procedure for interaction with providers and issuers of virtual asset services.
