Scientists from the University of Uppsala have discovered unusual black frogs in the exclusion zone near the Chernobyl nuclear power plant, supposedly protected from radiation. Scientific work published in Evolutionary Applications.

Black frogs were found in the Chernobyl zone.  Scientists believe that the pigment melanin helps them survive in radiation conditions.

Radiation damages the genetic material of living organisms and causes unwanted mutations. But sometimes radiation can favor animal organisms that are able to live in the zone of radioactive contamination, gain access to food and territorial resources that few people claim.

In 2016, next to a damaged nuclear reactor, scientists discovered several eastern tree frogs Hyla orientalis with an unusual black tint. Usually this species has a bright green color. Over the next three years, the authors analyzed the coloration of more than 200 male frogs caught in 12 different ponds both in the exclusion zone and outside it.

It turned out that frogs with a much darker color live in the exclusion zone. Some of them were completely black. Scientists suggest that the dark pigment melanin allows amphibians to live in conditions of increased radiation. Previously, such a function of melanin was found in fungi. The pigment absorbs and dissipates part of the radiation energy. In addition, it can neutralize reactive oxygen species that damage DNA and cell structures.

The accident at the fourth reactor of the Chernobyl nuclear power plant in 1986 led to the largest release of radioactive materials into the environment in the history of mankind. Today, this area has become a real nature reserve: a variety of rare species of animals find refuge here, including bears, wolves and lynxes.

Now Apple Watch Ultra can be used to the fullest

Despite the fact that the Apple Watch Ultra has been on sale for some time, only now the watch has received one of the important applications.

Now Apple Watch Ultra can be used to the fullest.  Oceanic+ diving app now available

Apple today announced the launch of Oceanic+. It is this application that actually turns an Apple watch into a diving computer. Since the watch can be submerged to a depth of 40 meters, this is not just marketing.

Interestingly, Apple did not develop the application itself. Even in the press release, the company says that it was created together with Huish Outdoors, which specializes in diving products.

Huish Outdoors specialists note that one of their main tasks was to make the software intuitive and convenient, since diving computers are usually very specific in this matter.

Oceanic+, among other things, allows you, for example, to plan your dive by specifying time, depth and other parameters in advance. The application is able, based on the input data, to calculate the no-decompression time, an indicator used to determine the time limit for a diver at a certain depth. The planner also takes into account diving conditions, including tides, water temperature, and even up-to-date information from the diving community, such as visibility and current strength.

Tesla wants to update Model 3 but primarily to reduce

Tesla is going to significantly change its bestseller Model 3. But we are talking about classic restyling.

Tesla wants to update Model 3, but primarily to reduce production costs

The project, codenamed Highland, is designed primarily to reduce manufacturing costs, but at the same time, Tesla also wants to focus on features that consumers love.

As one of the directions, the Reuters resource calls the reduction in the number of components and the complexity of the interior of the Model 3. Changes in the design may also take place, but there is no exact data yet. Recall that the Model 3 has been in production for five years, and automakers usually resort to restyling or at least facelift even earlier.

The updated Model 3 will be produced in Shanghai from the third quarter of 2023. Also, production can be established in California.

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.
