An “intriguing” new discovery made by Curiosity on Mars

Published

on

Despite its years of service on the planet Mars, NASA’s Curiosity rover continues to make fascinating discoveries. Lately, scientists have found something quite “intriguing” in the data collected by the rover. These are carbon signatures they discovered in samples analyzed by Curiosity. According to a NASA statement, these signatures could be “associated with biological processes”.

As you will have understood, we are talking here about “potential” proof of the existence of life on Mars. Scientists found them after examining 30 rock samples collected by the rover between the years 2012 and 2021. They detected distinct organic molecules that have been associated with life on Earth. Among these molecules, there were isotopes of carbon 12 which are used by terrestrial organisms to metabolize food or to carry out photosynthesis.

The study describing the discovery of these molecules was published in the journal Proceedings of the National Academy of Sciences.

The origin of molecules

Researchers have a theory regarding the origin of the molecules found on Mars. According to this theory, ancient bacteria could have released methane into the atmosphere. Later, ultraviolet rays were able to transform this methane into more complex molecules which fell to the ground to be preserved in the rock.

According to Christopher House, a Penn State researcher and first author of the study, on Earth, the processes that could have produced this carbon signature that was detected on Mars are biological.

No precipitation

Faced with this discovery, scientists remain cautious. For them, this is not yet definitive proof of the existence of Martian life.

According to Paul Mahaffy, former principal investigator of Curiosity’s SAM or Sample Analysis at Mars instrument, there are things on Mars that are very interesting, however, much more evidence would be needed to say that life has been identified. .

Thus, scientists will now try to find explanations or eliminate those that do not correspond to the discovery. For that, you need to have a vision that is not biased by what you see on Earth.

As Jennifer Eigenbrode, an astrobiologist at NASA’s Goddard Space Flight Center and co-author, explains, the hard part is getting away from Earth and prejudice, and really studying the fundamentals of chemical, physical, and environment of Mars. She added that you have to open your mind and think differently.

The days of Ethereum mining are numbered. Vitalik Butering told when the network will switch to the Proof-of-Stake algorithm

The days of Ethereum mining are numbered Vitalik Butering told

The transition of Ethereum to the Proof-of-Stake algorithm, instead of the current Proof-of-Work supported by miners, has been talked about for a long time, but so far this has not happened. However, Proof-of-Stake is on the way. This was stated by Vitalik Buterin himself.

The days of Ethereum mining are numbered.  Vitalik Butering told when the network will switch to the Proof-of-Stake algorithm

During the Shanghai summit, Buterin said that the transition of the Ethereum network to the Proof-of-Stake algorithm will take place in August. Previously, it was planned for the second quarter of this year (and before that it was postponed many times), but now a new date has been announced. In case of unforeseen circumstances, the update will be postponed for a month or two, but it is definitely not in the interests of the network to delay further implementation of Proof-of-Stake.

Thus, there is not much time left for cryptocurrency miners to mine ETH. There is an opinion that after the transition to the Proof-of-Stake algorithm, the cost of Ethereum may fall slightly, but then it will definitely increase. In the meantime, for 1 ETH they give less than $2,000.

I have an Android Galaxy Z Fold3 Bill Gates reveals

The former head of Microsoft does not use the company’s smartphones. Answering a question about his mobile device on the Reddit forum, Bill Gates told what kind of smartphone he uses.

I have an Android Galaxy Z Fold3 Bill Gates reveals

I have an Android Galaxy Z Fold3. I try different ones. With this screen, I can get by with a great laptop and phone and don’t need anything else.

Third-party sources, of course, emphasize that Gates could use the Microsoft Surface Duo 2, but, like the first generation, this device failed in sales and is inferior to Samsung’s foldable flagship on literally all fronts.

As for other smartphones or the laptop he chose, Gates, unfortunately, did not disclose the details.

Smart watches Google Pixel Watch can surprise you with the amount of memory: there will be more flash memory than in some smartphones

Smart watches Google Pixel Watch can surprise you with the

Google announced the smart watch ten days ago, but kept silent about the technical characteristics of the novelty. Therefore, details about the device have to be collected bit by bit. A previous leak said the watch would get Samsung’s rather old Exynos 9110 SoC, but the new data is encouraging: the Pixel Watch may have a fresher SoC.

Smart watches Google Pixel Watch can surprise you with the amount of memory: there will be more flash memory than in some smartphones

This scheme is not new, it has already been tested in a number of other wearable devices: a low-power SoC ensures that the device works for a long time with basic capabilities, and when all functions are supposed to be used to the maximum, a more powerful (and obviously more modern) hardware system is involved.

But even this is not interesting: Pixel Watch is credited with a lot of flash memory – as much as 32 GB. Such a volume for applications is clearly redundant, so it is suggested that Google will focus on the ability to download and store a large amount of music right on the watch. Which is good for sports. However, it will be possible to store podcasts right in the watch, for example. The amount of RAM will be “slightly more than the Galaxy Watch 4”. Samsung smartwatches have 1.5 GB of RAM, so it’s logical to assume 2 GB of RAM in Pixel Watch.

Finally, the Pixel Watch is said to be sensor-similar to the Fitbit Charge 5. This means that Google’s new product will provide the same vitals tracking capabilities. At a minimum, you can count on the monitoring of heart rate and SpO2, as a maximum – on the possibility of recording an ECG.

This concludes the new batch of details about the Google Pixel Watch. Recall that the novelty will go on sale in the fall.
