A new type of protective mask detects viruses in 10 minutes
If you’re someone who couldn’t stand masks during the pandemic, we’ve got good news. A new mask has been created that you will struggle to wear. why? Because this mask can detect pathogens in a maximum of ten minutes, and also sends a message on your phone to warn you. Enough time to take your insoles and escape uninjured. What could you have asked for more?
The mask was designed by specialists at Tongji University in Shanghai, China, and was able to detect up to 0.3 microliters of fluid containing viral proteins, which is 70 to 560 times less than what is eliminated during sneezing or speech. Moreover, he simultaneously detected SARS-CoV-2, H5N1 and H1N1 viruses.
Don’t rush to ask for it because you won’t get anything because it’s still on the test. The Chinese researchers, who published their achievement in the specialized journal Matter, say they want to improve it and reduce the time for detecting viruses, but also adapt it so that it can detect new pathogens. It hasn’t been said when it will hit the market yet, but it wouldn’t be bad if it’s useful until the pandemic is over.
For what reasons the albatross continues to “divorce”.
Albatrosses are monogamous birds. That is, they keep the same pair throughout their lives, a pair with which they meet every two years for mating. Why two years later? Because it takes about a year to raise their young, and that requires a frightening amount of energy, as those who have children know. Therefore, they take a year off before returning to work raising and educating a new generation.
Separation, or “divorce”, is a rare phenomenon, somewhere in 13% of couples they end up with something like this, and professionals have been wondering why they end up breaking up. Well, after much debate and research spanning over a decade, here we have the answer, beautifully published in Biology Letters. The conclusion is unexpected. More precisely, some males are more shy, and females do not sit down for discussions, but prefer the bravest.
To clarify, we will say that even in the case of albatrosses, there is competition. When they meet again, this is the custom, the male must court his mate, impressing her, even if they already know each other. Here other men intervene, on their own, who pay attention, trying to break up the spouses. It works for some for the simple fact that there are individuals who would rather give up family life than fight for it. As experts say, they are more shy. This is their way, you can’t help them.
Where do you say that there are fewer females than males, because they feed in areas where they often fall victim to fishing nets. This means that females can quickly find new life partners, while a single male can wait years to find someone. About the same with the sincerity of these albatrosses. That’s why they can’t be blamed when they bump into you on the beach and steal your food or leave some joy in your car. Don’t scold them, because you don’t even know what problems they also have in their marriage, you just don’t burn them anymore.
What an unexpected effect of forest fires
In 2014, specialists from the University of North Carolina and Laval University in Canada noticed an unusual phenomenon in the Arctic Ocean, a phytoplankton “boom”. These tiny algae have multiplied so much that they can be seen easily through satellite images. The problem is that no one knew how to say from where and until he reached the relevant position.
After eight years of searching where all possible options were considered, only to be eliminated one by one, the aforementioned specialists finally had the answer. For such an explosion to occur, a large amount of nitrogen is needed. US researchers say this nitrogen can only be produced by massive wildfires in Canada and Siberia. What they cannot say is whether or not the impacts are beneficial to Arctic ecosystems.
Until now, major fires were isolated phenomena and their effects were insignificant in time. As the fires intensify, the return of phytoplankton in the Arctic regions is expected to become a regular phenomenon. In principle, this would be good, because phytoplankton not only release about 50% of the oxygen in the atmosphere, but also represent the basis of the food chain in the seas and oceans of the world. Now, let’s see what the species that consume it have to say, too, with plenty of food on their heads.
How many ants are on earth?
When I read such a headline in the current magazine PNAS, my mind immediately went to a famous Jules Verne, Paganel, who, if I remember correctly from my childhood years, used to do all kinds of calculations like this: How many drops of water are in the oceans The planet, how many grains of sand are in the desert, how many ants roam the planet. Well, the renegades have Paganel, because a team of researchers from Julius Maximilian University in Würzburg, Germany, set out to do just that, to count how many ants are on Earth.
They discovered that about 20 quadrillion ants are alive today, 20 million trillion, a biomass greater than all birds and mammals combined. Also from the above study, we learned that ants are found in all habitats on Earth, except for those in the polar regions, which we already knew anyway.
The important question is what is the benefit of this information to us more than a dose of general education? Please, there will also be a reason as to why such accounts end up in journals like PNAS, but that’s more rhetorical. Well, German specialists claim, what they wanted to know is how the global distribution of ants will be affected by climate change, especially since the role of these insects in ecosystems is crucial.
In fact, this is not because, the study says, the mentioned calculations will only be the starting point for further, more comprehensive research. As expected, they astounded us with their information, but they got it out of the pen in the end. In conclusion, we are left with only the second question, which is by the way the most important, namely, how do such studies appear in high-impact journals such as PNAS?
