There may be underground volcanoes on Mars

Published

According to an article published in the journal Nature Astronomy, Mars may contain liquid magma capable of volcanic activity. Scientists were able to draw this conclusion by analyzing the seismic data obtained by the InSight probe. This device has been operating on the surface of Mars since the end of 2018, and since February 2019 it began to transmit information about the seismic activity of the “red planet”. During its work, the probe managed to record more than 1.3 thousand marsquakes.

As scientists have found out, often the epicenters of these marsquakes were located on the territory of the Cerberus Furrow (Cerberus Fossae) – a huge geological structure 1235 kilometers long. A closer analysis showed that a significant part of the centers are located inside a huge sinkhole at a shallow depth, which, according to the Mars Odyssey satellite, emits much more heat than other regions. Comparing these facts, the authors of the study made the assumption that the shocks were caused by the movement of magma in the near-surface layers of Mars. According to scientists, the Cerberus Furrow region generates about half of the total level of seismic activity of the entire planet.

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.
