Scientists have topographical evidence of the existence of subglacial lakes on Mars

Published

European planetary scientists have found topographical evidence in images from the Mars Express probe that several subglacial lakes are hidden under the southern polar cap of the fourth planet in the solar system. This discovery contradicts recent statements by their US colleagues that there is no liquid water on Mars, the press office of the University of Cambridge said on Thursday.

The combination of radar images, computer models, and the topographical evidence we have obtained is a strong argument that at least one region of liquid water exists under the ice cap of the south pole of Mars. If so, then the interior of the planet must remain geothermally active in order to keep this water from freezing.Neil Arnold, a professor at the University of Cambridge (UK), said.

In July 2018, Italian astronomers working with instruments from the European Mars Express probe reported a surprising discovery. They were able to detect on radar images of the south pole of Mars traces of the existence of three subglacial lakes located at a depth of 1.5 km from the surface of the southern ice cap of the planet.

Subsequently, astronomers discovered several more similar anomalies in radar images, which led scientists to actively discuss the nature of these findings. Many planetary scientists immediately doubted these findings and suggested that the instruments of the Mars Express probe discovered deposits of clay or other rocks, and not subglacial lakes of water. This has generated a lot of controversy around radar anomalies.

In particular, at the beginning of 2022, US planetary scientists analyzed images from Mars Express and came to the conclusion that the liquid water reserves discovered by the probe are a kind of “radar mirage”. A group of European astronomers, led by Professor Arnold, have discovered topographical evidence that their fellow skeptics are wrong in their estimates.

As planetologists note, subglacial lakes that exist on Earth have a special effect on the topography of the ice surface in their vicinity. This is due to the fact that these reservoirs reduce the friction force between the base of the glacier and the rocks along which the ice mass moves, as a result of which it “sags” at the point where the under-ice reservoir is invisible to the eye, and then the glacier rises sharply.

Based on similar considerations, Professor Arnold and his colleagues calculated how the glaciers of Mars would behave under similar conditions. Scientists used this information to analyze detailed images of the southern polar cap of the fourth planet in the solar system at the points where Mars Express supposedly discovered subglacial reservoirs.

As it turned out, on the southern polar cap of Mars there are several regions at once with characteristic depressions and rises, similar to how subglacial lakes on Earth influence the topography of the area. The position of many of them coincides with the points where the radars of the Mars Express probe found traces of the existence of lakes. This, according to Professor Arnold and his colleagues, speaks in favor of the fact that liquid water on Mars exists rather than absent.

Huobi and Tron Jointly Launch Dominica National Token Dominica

Crypto exchange Huobi today announced a strategic agreement with the Tron network, DMC Labs, and the government of Dominica. As part of this deal, the parties will jointly issue the world’s first national token, Dominica Coin (DMC).

Moreover, at the same time, a virtual ID protocol called DID will also be launched on the Tron platform. DMC holders will automatically receive a “digital citizenship” of Dominica.

Dominica DIDs and DMCs will initially be released on the Tron network, which is Dominica’s national blockchain infrastructure. In the future, the developers plan to ensure the interaction of the DMC token with the Ethereum and BSC networks via the BitTorrent Chain protocol. Just like TRX and USDD tokens, DMC will have legal status in the Commonwealth of Dominica and can be used as a means of payment in this country.

DMC will be released on Huobi Prime. The exchange will conduct a distribution of DMC tokens and enable the Dominica DID application for each registered user, the announcement says.

DID holders can also use the ID to issue SBT tokens in the Tron ecosystem. This will open up the possibility for them to become Dominica citizens in a future blockchain-based metaverse.

After paying the fee, you can also receive a printed certificate of your status. However, it is not yet completely clear whether such a document will have legal force outside the country. DID can also be used to complete KYC verification, obtain a loan in Dominica, register a virtual company, and a number of other government services.

When the GeForce RTX 4090 is a wolf in sheep’s clothing. Card consumption can be reduced by 33% by sacrificing 8% performance

When the GeForce RTX 4090 is a wolf in sheeps

Contrary to early leaks and rumors, the GeForce RTX 4090 turned out to be very energy efficient and even more economical than the RTX 3090. But Nvidia’s new product can be made even less voracious.

The authors of the QuasarZone resource decided not only to achieve less power consumption from the RTX 4090, but also to achieve this in two different ways. The first is reducing the power limit, but the second is more complex – it is undervolting or reducing the voltage on the GPU.

As you can see from the diagrams, both methods are effective, and in both cases you can achieve an impressive reduction in power consumption with a slight drop in performance. In the case of power limit management, power consumption can be reduced to 268 W, with a loss of only about 6% of performance. Reducing the voltage allows you to achieve power consumption of only 232 watts, sacrificing less than 8% of performance.

Thus, the RTX 4090 can be turned into a mid-range card in terms of power consumption, while keeping its monstrous performance almost unchanged.

For some reason new Intel processors do not support DLVR

Intel was expected to endow Raptor Lake processors with DLVR (Digital Linear Voltage Regulator) technology. Information about it appeared last year. However, it has now become known that current Intel CPUs do not support it.

For some reason, new Intel processors do not support DLVR technology, designed to reduce power consumption

Information about DLVR was neither in Intel’s presentation, nor somewhere on the site describing Raptor Lake. However, the CPU DLVR Bypass Mode Enable item has appeared in the new BIOS of Asus motherboards. True, its activation does not lead to anything.

For some reason, new Intel processors do not support DLVR technology, designed to reduce power consumption

One of the overclockers from the Asus team said that the technology does not work because Intel eventually disabled it in the new generation of processors. For what reasons, it is not clear, but from the tests we know that, perhaps, in vain, since Raptor Lake turned out to be even more voracious than Alder Lake. However, next-generation CPUs may well support the new technology already fully, however, there is no clarity on this matter.

DLVR is a digital linear voltage regulator that complements the main one. This should allow a significant reduction in energy consumption.
