Artificial intelligence (AI) has unimagined potential uses that can prove useful in the fight against climate change – such as the major challenges that wildfires, floods and severe droughts can pose. The irony, however, is that AI itself is not carbon neutral.

With climate change, farmers, to name just these workers, are facing more numerous and complex challenges than ever. The higher temperatures not only lead to more and more diseases, but the harvest calendar is also thrown into disarray. In southern countries, plagues of locusts (pest locusts) are becoming increasingly common, threatening food security.

For reading and listening:

A new tool called Kuzi – in honor of the Swahili name for the European starling, a bird known for eating grasshoppers – is giving farmers a boost by providing real-time data from satellites and ground-based weather observations, as well as surface temperature, soil moisture, vegetation index etc.

Kuzi displays a heat map of high-risk areas along with breeding, swarming and migratory attack forecasts that can alert farmers and ranchers to a possible invasion two to three months before the event. The tool can even send SMS alerts when locusts are likely to attack farms in an area, including livestock farms.

Recognizing diseases in potatoes

The AgriRobot, developed by Charan Preet Singh, a master's student in the University of Prince Edward Island's Department of Sustainable Design Engineering, is a robot that is trained using AI to detect diseases in potato plants.

This small, four-wheeled black device with two outstretched arms moves through a row of green leaves, its huge tires churning up the earth. A map is created with the information necessary to identify and eliminate infected plants, explains Aitazaz Farooque, associate dean of the School of Climate Change and Adaptation at Prince Edward Island University.

Beavers fighting drought

With the information provided by AI, conservationists will also be able to more easily identify new locations for beaver reintroduction.

As droughts, floods and fires increase, beavers are helping to make all three worse, said Emily Fairfax, an assistant professor of geography at the University of Minnesota whose research focuses primarily on the ecological role of beavers.

Emily Fairfax specializes in ecohydrology, the interactions between water and ecosystems.

In fact, beavers are incredible engineers – building dams, ponds and wetlands that conserve millions of gallons of water.

By storing large amounts of water both above ground in ponds and underground, beavers create these large spongy areas in the landscape from which plants can absorb water in times of drought – and which are simply too wet to burn in dry times. There is one Fire phase, says Emily Fairfax.

These structures also reduce the impact of erosion and flooding, she adds.

Detect forest fires

Germany-based Dryad Networks has developed solar sensors that can detect a fire even before a flame breaks out.

The company has already deployed 20,000 of its sensors worldwide, with a pilot in a portion of California's forests.

Forecasting extreme weather conditions

As the risks of climate change increase, engineers and scientists are developing new tools to detect and even predict extreme weather events that have become part of our reality and are likely to occur more frequently in the coming years.

Whether it's helping us better predict solar and wind energy on the grid to better integrate it into grids, or helping us map deforestation and emissions using global satellite imagery, AI is coming to the rescue in a variety of ways used for climate protection measures.

The irony is that while AI helps adapt and mitigate climate change, it has its own problem with carbon dioxide (CO2) emissions. While it may seem invisible to most people, the computers that run it are housed in data centers that require a lot of power. If that electricity comes from a fossil fuel grid, AI in turn contributes to emissions.

Additionally, the servers in these data centers generate a lot of heat and need to be cooled, which often requires more power.

The other side of the coin

However, the computers that run the AI ​​are housed in data centers that produce a lot of heat and require a lot of electricity. Despite the fact that AI has enormous potential, it is imperative that we have a better idea of ​​its contribution to emissions, experts argue.

Experts do not yet know what contribution artificial intelligence makes to emissions from data centers.

We really need to pay attention to AI’s growing emissions footprint. Fundamentally, there is insufficient transparency between the data center providers and the machine learning units that create algorithms to monitor and measure greenhouse gas emissions.

Of course, energy requirements vary depending on usage. A recent study suggests that AI uses enough energy to charge a cell phone every time it generates an image.

Priya Donti therefore emphasizes that we need to re-evaluate what uses are worth the electricity consumed and review our practices. “We should definitely not believe that artificial intelligence has no environmental impact or cost,” she concludes.

We now know that the moon contains more water in its rocks than the samples brought back by Apollo suggest. A new study now reveals that the early moon's magma ocean must also have been rich in volatile elements.

This will also interest you

[EN VIDÉO] New scenario for the formation of the moon New simulations with a supercomputer show that the moon could have formed…

Water on the moon? The idea may seem completely far-fetched. And for good reason, all of the samples brought back by the ApolloApollo missions showed that there were almost no volatile elements present in the lunar rocks. Thanks to new analysis, we now know that the moon is not as dry as previously thought and that it even contains impressive amounts of water, trapped in microscopic glass beads.

Ferroic anorthosites, remnants of the lunar magma ocean

A new study now shows that water has always been present on the moon, especially shortly after its formation. It is worth remembering that the moon was formed about 4.5 billion years ago after the gigantic collision between a small planet and the Earth. The material thrown into space will quickly transform and create our natural satellite.

As a ball of magma, the moon then begins to cool, which leads to the crystallization of an initial crust. Fortunately, some fragments of this crust came to us thanks to meteorites. They are composed of ferroanorthosites, which have the peculiarity of not containing apatite, a mineral that contains volatile elements. Well, that's what we thought.

A primitive moon that isn't so barren after all

For the first time, researchers have identified apatite in a meteorite that belongs to the ferroic anorthosite group. These results, published in the journal Nature Astronomy, therefore indicate that the primordial moon must have been much less free of volatile elements and especially water than previously assumed.

Lip volume injections are very trendy. What are the most frequently asked questions in the clinic?

During consultations, mature women tell me that they would like to have more volume on their lips again, but they are very afraid that it will look like a caricature. Older women ask me a lot of questions about this topic, they are very hesitant because what they mainly see are young women who have opted for a lot of volume and very full lips thanks to injections. I want to demystify these fears of readers, dispel them, because you can get there gradually to have full control over your appearance!

“Ladies, you need to know that YOU are in control of what you want. The result can be quite subtle. The appearance of the lips can be easily increased, the lips can appear more moisturized and more defined. In no case will you be forced to a very obvious result. With a trust injector you have full control over the outcome. The person who cares about you will take the time to listen to you to understand what you want. »

What are the steps for those who want to get started?

First of all, you need to make an appointment. Before the first lip filler treatment, a consultation takes place to determine the next steps together. We need to complete the medical file, then you will meet the clinic doctor. Here we work with Dr. Colin and Dr. Pinard together; We must consult a doctor to obtain the prescription of the file. An appointment will then be made for the first lip enlargement treatment.

The before and after result thanks to voluminous lip injections.

How does the first date go?

The client is interviewed to determine the purpose of the intervention. I ask her to look in the mirror and tell me what is bothering her. Is it the small vertical wrinkles that appear around the mouth over the years? Loss of lip volume (thin lips)? Lack of upper lip definition, lip contour? What I often hear from women in their 40s, 50s or 60s is, above all, that they want to find their “before” mouth, beautiful, fuller lips. For older clients, we move away from intense volume and are asked to rework the shape of the lips to find the original structure rather than exaggerate the contours.

For my more concerned clients, I will prefer to use less and inject in a different way. I will adapt to the customer's wishes to ensure his complete satisfaction.

Are there any health contraindications?

Yes, but they are still quite rare. If the patient suffers from a serious illness, cancer or other diseases, has a serious medical history or is taking certain medications, lip volume injections may be contraindicated. In general, this little help is within everyone's reach.

Is it a painful procedure?

The lips are the part that is a little more delicate and sensitive. Before the injection, we apply an anesthetic cream that freezes the treated area well. I use fine needles to redefine the lips. Once the procedure is complete, it no longer hurts.

How long does it take until the optimal result is visible?

Immediately after the lip injection, there is a slight swelling, a slight swelling. The result is therefore minimally worsened, but not intensified. There are no bruises; Some customers may experience very mild symptoms the next day. However, it can be easily camouflaged with a little foundation and lipstick. We will see the final result 2 to 3 weeks later.

The before/after result of a customer at St-Laurent Médico-Esthétique.

How often are procedures to maintain lip volume performed?

The client should plan to return to the clinic approximately twice a year. If she decides to stop after a few years, it will have no effect on her face. Your lips will be back to what they were, neither worse nor better! It's a bit like stopping using a cream. Women will not notice any distortions in their body shape.

As with everything, moderation is the secret. In the hospital St-Laurent Medical AestheticsThis is our mission: to provide women with high-quality medical-aesthetic care using state-of-the-art technologies at an affordable price.

Our approach is to use our care and good taste to restore the self-confidence of women who desire it. Several clients confess to me that they were afraid at the first appointment because they thought that they would be offered very volumizing injectables, in short, a series of procedures that would change them forever.

Ladies, a little tip: If you come out of a consultation and have needs that you didn't have before you came in, you are not in the right clinic.

Take the time to find someone you trust completely because your face matters. If you choose medical aesthetic treatments, also take the time to find a trustworthy partner who will bring out your natural beauty. The goal is not to make the woman appear younger, but to increase her size.

What do your customers say when they come out of lip volumizing injections?

Most importantly, they tell me it doesn't hurt as much as they thought. They are happy to see that their fears were unfounded and that their lips are fuller without looking exaggerated. Above all, they tell me: “So I should have done that sooner!”.

The result of lip volumizing injections can be quite subtle; Here is the proof.

From grayscale to ultraviolet. The spectrum of what animals that share our environment can see is wide. To better understand how they make sense of the world, researchers have developed a camera that allows us to put ourselves “in the eyes” of some of these animals.

Animals don't have the same photoreceptors as we do. Each animal even has its own photoreceptors. Understand that every animal sees the world in its own way. And to account for this different perception of the colors that surround us, researchers at the Hanley Color Lab at George Mason University (USA) and the University of Sussex (UK) have developed a camera and software capable of to film the colors of the world as animals see them. They explain the principle in the journal PLOS Biology.

The moving world from the animals' perspective

You could say researchers have already shown us how our dogs perceive colors. Yes. But this time the system allows us to understand a world in motion. And that in natural lighting conditions. It reproduces what biologists know about the photoreceptors found in the eyes of different animals. With an accuracy of over 90%.

Do dogs really see the world in black and white? The answer with Melissa Lepoureau in Science ou Fiction. © Futura

The system is based on two separate cameras. The light is divided and directed at the same time to a camera that reacts to ultraviolet light – because bees, reindeer and certain birds react to it – and to a standard camera that reacts to light visible to humans.

A system that is open to improvement

The precision achieved by the researchers shows what influence clouds can have on color perception in the animal world. And by basing their system on a commercially available camera and open source software, they hope others can adopt it and improve it further. For example, to better capture fast movements. To ultimately help us better understand how animals communicate and develop in their environment.

Do you suspect someone has blocked you on Messenger? Here are the tips to help you find out.

Can't contact anyone on Messenger? No answer or the message doesn't seem to have reached him? Sometimes we feel like we are blocked by a contact on Messenger, Facebook's instant messaging application. If someone blocks you on Messenger, they may choose not to message you, which feels like they're sending a message on the wind.

Before we give you tips to find out if someone has actually blocked you, Warning about online harassment. If someone has actually blocked you, it's probably for a good reason. So if you have confirmation that you are indeed blocked by her, please respect her decision and avoid finding another way to contact her. Remember that online harassment is a criminal offense and the perpetrator could face a prison sentence of up to two years and a fine of up to 30,000 euros.

How do you know if someone has blocked you on Messenger?

First of all, Messenger gives no indication that someone has actually blocked you. However, some details might alarm you. If You cannot see your contact's last online time or online status, which may mean that this person has blocked you. However, it is possible that the person has simply deactivated their online status or has not been online for a while.

When you send a message to a contact, the message “Sent” appears to indicate that the message has been… sent. If the circle with the profile photo does not appear below the message after a certain period of time, this may be an indication that the person has blocked you. However, it could also mean that the recipient hasn't opened the message yet, especially if it's a contact you don't chat with often. In some cases, Messenger may also display a warning when you send a message, e.g. For example, “Message not sent” or “This person is not receiving any messages at the moment”, but this display does not occur very often.

Another element that might give you a clue: if the person's account does not appear at all when searching, this may indicate that their account has been deleted instead of blocking you. Here are just a few pointers that might give you food for thought.

Photosynthetic structures have been observed in fossilized cells that are 1.75 billion years old. A record.

These structures, called thylakoids, were discovered in microfossils of cyanobacteria (Navifusa majensis) discovered in the McDermott Formation in Australia by paleobiologist Catherine Demoulin and her colleagues at the University of Liège in Belgium.

A thylakoid resembles a flattened spherical vesicle. It's like a space inside a cell surrounded by a membrane, explains biologist David Morse of the Plant Biology Research Institute at the University of Montreal, who was not involved in the study.

The entire photosynthesis machinery is located in these flattened spheres, the scientist adds.

Sightseeing features

• Oxygenous photosynthesis, in which sunlight catalyzes the conversion of water and carbon dioxide into glucose and oxygen, is unique to cyanobacteria and related organelles of eukaryotes.
• Eukaryotes are all single- or multicellular organisms whose cells have a cell nucleus and organelles bounded by membranes.
• Oxygen-containing photosynthesis played a fundamental role in the emergence of life on Earth. It caused a major ecological upheaval by transforming a methane-rich atmosphere into today's atmosphere, which consists essentially of nitrogen (78.08%) and oxygen (20.95%).

Normally bacteria do not have an internal membrane. But cyanobacteria are a major exception to the rule! notes the scientist, who considers this work convincing.

In the microscopic images we can clearly see a cell with several lines in it. We do not observe these types of structures anywhere other than in cells with thylakoids.

The role of thylakoid-equipped cyanobacteria is considered by several biologists to be crucial in the intense oxygenation of Earth's atmosphere 2.4 billion years ago, which profoundly disrupted the development of early life on the planet.

However, this hypothesis has not yet been confirmed in the fossil record by the discovery of physical evidence that would confirm this chronology.

There is a discrepancy between the start of the increase in oxygen concentrations on Earth and the appearance of organisms with thylakoids in the fossil record, says David Morse of the Plant Biology Research Institute.

Closer to great oxygenation

In fact, the oldest known thylakoid fossils were 550 million years old. The fossils we have identified therefore make it possible to push back the fossil record by 1.2 billion years, explains paleobiologist Emmanuelle Javaux.

It is therefore still not possible to establish a cause-and-effect relationship between thylakoids and high oxygen enrichment, notes David Morse.

Since the oldest fossils containing thylakoids are 550 million years old and the increase in oxygen began 2.4 billion years ago, we can't prove anything.

But recent discoveries bring us closer to proving that cyanobacteria and thylakoids are involved in oxygen enrichment in Earth's atmosphere.

But the chronology of the origin of oxygenic photosynthesis and the type of cyanobacteria involved in the large-scale oxygenation remain controversial, points out David Morse.

Could another source be responsible for the oxygen increase, such as proto-cyanobacteria unknown to science?

According to Mr. Morse, the discovery, described in the study published in the journal Nature (New Window), allows us to glimpse the possibility of discovering thylakoids in even older fossil cyanobacteria.

And thus prove once and for all the role of thylakoids in the massive accumulation of oxygen on Earth. We're getting closer to the magic number of 2.4 billion years, notes David Morse.

Emmanuelle Javaux reminds us that microscopic life represents the most diverse and abundant life form on Earth since the origin of life. Studying its fossil record using new approaches allows us to understand how life has evolved for at least 3.5 billion years. Some of this research even shows us how to search for traces of life beyond Earth, she concludes.

In 2023, Nintendo gamers were particularly spoiled when it came to the house's mascot: Mario. In addition to a new Super Mario RPG released at the end of the year, Nintendo Switch players were also able to discover the brand new Super Mario Bros. Wonder, a series that sold several hundred thousand copies in France. In total, Super Mario video games were sold more than 2.7 million times in France in 2023.

Buy Mario vs. Donkey Kong on Nintendo Switch at the best price

A new Mario game on Nintendo Switch?

And what better way to start 2024 than a new Mario game on Nintendo Switch? Older gamers probably remember the first appearance of Mario, aka Jumpman, in the video game Donkey Kong in the early 1980s. Twenty years ago, Nintendo offered a new game on the Game Boy Advance that brought the two famous characters together.

You will have understood, it was already about Mario vs. Donkey Kong, a platform and puzzle game directly inspired by the Donkey Kong game released in 1994 on the Game Boy. Officially released on September 14, 2023, this Nintendo Switch version is in fact a remake of the same work originally released on GBA in 2004.

When will Mario vs. Donkey Kong be released?

Just as Super Mario RPG was not a “classic Mario game,” it should be made clear from the start that this Mario vs. Donkey Kong is not a platformer. There are levels designed in such a way that the player has to think carefully to achieve his goals. You must use various mechanisms activated by switches and show a real sense of timing and logic to complete each level.

Mario vs Donkey Kong will be available February 16th next.

Note that two sequels were offered on the Nintendo DS in the late 2000s, namely Mario vs. Donkey Kong 2: March of the Minis and Mario vs. Donkey Kong: Chaos in Mini-Land! It remains to be seen whether these will soon be updated.

Where can you play Mario vs Donkey Kong?

Nintendo license required, Mario vs. Donkey Kong will be available exclusively on Nintendo Switch.

Apparently, the game will be playable on the different iterations of the Nintendo console (classic Switch, Switch Lite and Switch OLED), which is expected to sell over 8 million units (in France) this month of January.

Of course, with this Nintendo Switch version you can benefit from various new features with a total of more than 130 levels. There are also new obstacles, a “relaxed” mode or even the ability to play locally with two players.

Mario vs. Donkey Kong: Price and Collector's Edition

Mario vs. Donkey Kong will be available in the digital edition but also in the physical version. The game is listed in the eShop for €49.99. At Nintendo, with every pre-order of the game, the buyer receives a small keychain with the image of the game.

Apparently you can already purchase the game at a cheaper price from various resellers. This is particularly the case on Amazon, where Mario vs. Donkey Kong is offered for “only” €39.99.

Mario vs. Donkey Kong, what's the story?

In Mario vs. Donkey Kong, Nintendo's famous gorilla really wants mini Marios, the new toys that are all the rage but are sold out everywhere… So he came to the factory that makes them. she produced and stole entire production!

Since Mario the plumber fails to save another princess, this time he has to hunt down the monkey with the red tie to retrieve all the toys. To achieve this you will have to go through levels full of puzzles. As you complete each level you will receive the key that opens the door behind which there is a mini Mario.

I take advantage of the offer

The full review of Mario vs. Donkey Kong will soon be available on the website of Presse-citron.
