The Arctic cold was the ideal barrier against invasive species. Now that barrier is falling

by

The Arctic Ocean is one of the hot points as far as climate change is concerned. Separated from the surface by polar ice, this ocean is a place with its own characteristics that go beyond its icy temperature. The barrier falls. A new study headed by researchers at British Antarctic Survey (BAS) He has found evidence of the arrival of an invasive species of Percebe to the waters of the Canadian Antarctic. This has led the team to conclude that the barrier that previously represented the low temperatures of the polar ocean is falling. Amphibalanus Impherevisus. The species in question is a type of Balánido sometimes known as bay’s percebe (Amphibalanus Impherevisus). These crustaceans are disturbed in a distant way with the common perclabes (Cornucopia policipes), but its presence is considered a problem and not A food source. The species has already become a regular of the waters of Europe and the Pacific Ocean, where it causes problems when attached to ships, pipes and infrastructure of different types. However, until now it had remained absent in the waters of the Canadian Arctic. EADN. The detection of the invasive species was carried out thanks to the study of the bars coding of the Environmental DNA (Edna). Living beings are leaving our genetic imprint in our environment: detached cells, waste and other biological remains. This technique allows to detect the presence of a species (or several) without finding a single specimen, only through environmental samples, in this case, water. The details of the study were Published in an article In the magazine Global Change Biology. Climate change, the great suspect. The Arctic is one of the regions most affected by climate change. There are two factors, both related to the increase in temperatures in this region, which have contributed to the expansion of this percebe. The first factor is the increase in maritime traffic of the Arctic associated with the thaw and the opening of new routes. Generally, the team explains, these invasive species usually arrive in the ships of the ships or in their ballast tanks. The second factor is that the waters of the Canadian Arctic no longer present such hostile conditions for the proliferation of foreign species. “Climate change is really in the nucleus of this problem. The ships are increasing in number because the reduction of sea ice has opened new nautical routes. It adds to this that the invasive species that the ships bring to the Arctic also are more likely to survive and establish populations due to the warmest temperatures of the water,” explained in a press release Elizabeth Boyse, who led the study. An issue to clarify. According to the team responsible for the study, there are still details to corroborate with respect to the spread of this species in the Canadian Arctic, starting to know if the DNA detected responded to larvae in transit or a more stable and fruitful population. To know this type of detail, it will be necessary to complement the study with other techniques, such as direct observation of animals.

The science of sleep is clear about the ideal time to go to sleep

by

Under normal conditions, six out of ten Spaniards sleep little and badly. What happens is that we are not “in normal conditions”, we are in September: a month in which the return to the routine and the autumnal asthenia They shake hands to immerse ourselves (hopefully temporarily) in a dreams of bad quality. And yes, that is a problem. Lack of sleep is related to immunological problems, Metabolic, Cardiovascular emotional and cognitive; With disorders such as diabetes or of the obesity. Not just that sleeping little causes us to be more tired and irritablebut Raise our stress levels And it makes us Assume more risks And make more wrong. But what is “lack of sleep? To get an idea, although optimal amounts change from one person to anotherall medical associations specialized in sleep recommend sleeping between seven and eight hours of sleep every night. Well then, According to the Spanish Sleep Societythe Spaniards sleep an average of 6.8 hours during the week. In addition, “75% of Spaniards wake up at least once At night, and 3 out of 10 directly affirm that they suffer from insomnia. “And, eye, the scientific evidence available tells us that we tend to think that we sleep better than we really do. Reality, surely, is much worse. And what do we do? The tips to improve “sleep hygiene” are known: Monitor food: A balanced diet, a light dinner and limited consumption of caffeine, alcohol or other stimulating substances. Create an adequate space: Quiet, pleasant, little illuminated and with a pleasant temperature. Exercise strategically: Fundamentally, playing sports regularly, but always a few hours before sleeping. And, above all, establish regular schedules: Go to bed and lift, as far as possible, always at the same time (including weekends). Although, of course, that leaves us a clear question: When are we going to sleep? That is, if we want to establish a clear and inflexible schedule, we need to know not how many hours we have to sleep, but what is the best time for it. And yes, this is hardly generalizable. Above all, because sleeping hours collide directly with things like our work, our family life or our leisure habits. However, we have some ideas that can help us. Let’s go to the data. The best study we have was carried out in 2021. In it, The European Cardiology Society used UK Biobank records, one of the most important medical and lifestyle information repositories in the world (with more than 500,000 volunteers between 37 and 73 years old). They selected 88,926 adults (with an average age of 61 years) that had taken some type of wrist device capable of registering the physical activity of the person for at least seven days. After analyzing a period of 5.7 years, they discovered that going to sleep between 22:00 and 23:00 at night is associated with a lower risk of developing heart disease (already other related problems). In comparison, going to sleep between 23:00 and midnight entails 12% more risk of having this type of disease. Risk that rises to 25% for those who go to bed after twelve at night and stands at 24% for those who go to bed before 22:00. Can we move it directly to Spain? No, the truth is that no. It would be naive to think that the recommended schedules for a culture of copious and early dinners (such as English) are the same as those of a culture of light and late dinners (such as Spanish). However, they are the best data we have and, as María José Martínez Madrid saysCoordinator of the Chronobiology Working Group of the Spanish Sleep Society, the key relationship “comes mainly because of the mismatch that produces falling asleep late in the biological clock.” Therefore, it is a good indicator to reflect on our sleep guidelines. Especially now that, after summer, the world “starts again.” Image | Shane In Xataka | Thus influences the time to go to bed in the risk of developing a heart problem: these researchers believe they have found the exact time to go to sleep

Mediterranean countries seemed ideal for solar panels. Until the dust storms arrived

by

The Mediterranean has always been seen as a privileged land for solar energy: abundant sun, large extensions and A clear commitment to renewables. However, two factors that come from the south and of the climate change are putting this equation in check: the dust storms of the Sahara and the sustained increase in temperatures. The short. A new study warns that Sahara dust can reduce solar production in southern Europe by up to 50 %. Work, Posted in Renewable Energy magazine By the Hun-Ren Research Center of Astronomy and Earth Sciences of Hungary, analyzes the episodes between 2019 and 2023 in Portugal, Spain, France, Italy and Greece. More in depth. To reach these conclusions, the scientists resorted to a data arsenal: the forecasts of the European Network of Transport Systems Operators (ETSO-E), NASA MERRA-2 reanalysis, the European database Copernicus Cams V4.6 and satellite cloud and aerosols. Thus they were able to evaluate time and daily how dust alters solar irradiance and, therefore, the ability of panels to produce electricity. The additional finding is worrying: the current photovoltaic forecasts for the next day usually fail. In Spain and Portugal they tend to underestimate the real loss of energy (up to 15% less than expected), while in Italy and Greece the opposite occurs, with overestimations of up to 10%. A problem that aggravates. Saharan dust is not a new phenomenon, but climate change is intensifying both its frequency and its reach. And Spain, as a study of the Polytechnic University of Catalonia (UPC) warns collected in Xatakait is a true “hot point” of European warming. In the last 50 years, temperatures have increased 3.27ºC in the Iberian Peninsula and the Balearic Islands, more than double the Mediterranean mean. Summer has extended 36 days, rainfall has decreased almost 20% and desertification advances by regions such as Murcia, Almería or Alicante. The scenario for 2050 is a country with steppe or even almost desert climate in much of its territory. If Spain becomes a warmer and more dry desert, dust storms will be more frequent and its impact on even greater solar energy. Is there a possible solution? Until now, the great enemy of conventional solar panels was not only dust, but also heat. As we have developed in Xatakafor each degree above 25ºC, traditional plaques lose between 0.05% and 0.34% efficiency, which can translate into falls from 10 to 25% in very hot days. But a recent study by Laughborough University proposes a script turn: The so -called photoelectocrochemical flow cells (PEC). This experimental technology not only supports heat, but takes advantage of it, with an optimal point around 45ºC. In addition, it does not require active cooling, which lowers installation and maintenance costs. In parallel, startups like the Australian Coolsheet They are developing Passive cooling hybrid systems that cool the panels and, at the same time, heat water for industrial or domestic use. Every 10º less on the plate can be 4% more electrical efficiency. Beyond the results. The research is not limited to more solar panels, but that It must be integrated In the new photovoltaic, more forecast of dust effects, improve real -time monitoring and design technologies that convert heat and extreme conditions into allies, not enemies. Spain and the Mediterranean advance towards a scenario in which the sun will be more abundant, but also more hostile. The future of solar energy is to accept this paradox: it is not just about installing panels, but of adapting them to a changing climate, full of dust, heat and drought. Scientific research, technological innovation and political planning must go hand in hand so that the sun remains the solution, and does not become part of the problem.

We have some ways to find the ideal place

by

Although there are still a few days to reach their maximum activity, The Perseids They are here. The most popular rain of stars will be elusive again because of the moon, which will be in its luminous phases during the days when the rain of stars reaches its climax. Fortunately, that does not mean that we cannot see them. In emptied Spain. Every year, thousands of people take advantage of summer to return to the peoples that their parents and grandparents abandoned to look for life in cities, emptied Spain. This vast rural region presents an ideal opportunity for those who want to enjoy astronomy, an opportunity that many visitors have not wanted to waste that, without a specific link, choose rural Spain as a destination with the aim of escaping from light pollution. The Perseids. Perseids are perhaps the most iconic rain of stars in the northern hemisphere. Its origin It is in small pieces of ice and rock scattered throughout the comet 109p/Swift-Tuttle In its orbit. Towards the beginning of August, the orbit of our planet crosses this path, which causes some of these particles to be captured by gravity, fall and disintegrate burned in the planet’s atmosphere, shining incandescent. The flashes of this rain of stars are becoming more frequent night by night as we get closer to the dates on which the meteor rain reaches its climax, which usually happens Around August 11 and 12 (This year will be the day 12 around 22:00peninsular time). On a clear night, the Perseids can produce at this point about 140 fleeting stars every hour. The pollution problem. This year it will be difficult to see this peak since the full moon will take place only three days before, on August 9. This implies that our satellite will be an important source of light pollution, which reduces the contrast that our eyes need to see these fleeting stars. To dodge the moon, we can try to take advantage of these days in which the Perseids approach their peak, but for this we will have to dodge another source of light pollution: the artificial lights of cities and other urbanized areas. That is where the vast extension of areas with low population density, the “donut” emptied between Madrid and the urban areas of the coast comes into play. Looking for the best places. Fleeing from the city to see the Perseids seems like a good idea but, where are we? Choosing destination can be a bit more complicated than it seems, but we have some tools at hand. The first is the map of light pollution created just over a year ago by a team from the Complutense University of Madrid and the CBAS (International Research Center of Big Data For Sustainable Development Goals). This is The map further accurate of light pollution in Spain and Portugal. The map covers most of the Iberian Peninsula and the archipelagos of the Balearic Islands, the Canary Islands and Madeira (not the Azores). We can also resort Apple -shaped maps For the mobile phone, such as ‘Light Pollision Map – Dark Sky,’ that also has a page web that we can consult from our browser. The other space tourism. Many rural areas have seen a new hook in Astrotourism to attract visitors to the rural environment. In this sense, this year’s persistent can be seen as a prelude to what will come next year: The eclipse that will travel the peninsula, predictably bring thousands of people to the areas that will be covered in sunlight. Local institutions have transformed this interest into actions to promote astrotourism through promotional companies and campaigns. An example is that of the City of Benavente, which last weekend celebrated His first ‘Astro Tourism Festival’, already with the attention set in the great astronomical event next year.

The blackout in Spain has demonstrated which is the ideal means to inform in a crisis: the radio

by

In the minutes that followed the Broady in Spain and Portugal At 12:32 yesterday, millions of people They wondered The same: “What happened.” In other crises, television, newspapers and of course the Internet are the clear alternatives to find out what is happening, but yesterday that was not possible. Almost everything failed, but there was a means of communication that allowed us to keep us informed: the radio. Where is the FM radio of the mobiles. The fragility of our communications caused the radio to erect as a unique solution to keep us informed. The mobiles had support for FM radio years, but this feature has disappeared in all current models. In fact It went from being an extra desired to an exclusive function of cheaper models. Something older mobiles do have that function by connecting headphones (which bend as antenna), and that allowed those who still have any of those mobiles could be informed thanks to that functionat least while the mobile battery lasted. Some brands keep them in some models. Xiaomi is one of the manufacturers that still includes support for FM radio in some of its Redmi family models, but of course not all. He Xiaomi Redmi Note 14s or the Redmi 14c They are good examples. The normal thing is that in recent terminals we will not find that option, which we can enable in older mobiles (such as Little m5he Motorola G73 5g or the Samsung Galaxy M23 5g) and also in input range terminals and in less extended brands such as Doogee or Ulefone. Radio as informative lifeguards. Without light there was no television or wifi in houses and offices, and connect to the Internet It was an odyssey all day: Mobile lines, the only ones that could give a way out, worked irregularly … If they worked. And yet, the radio worked without apparent problems. Transistor to batteries. Meanwhile, those still kept a battery transistor at home could be informed thanks to the radio stations continued to broadcast during the blackout. These transistors became the salvation of many citizens, who either had radios in their homes or gathered in the streets around vehicles with analog radios or that could listen to the radio What other people had in the streets or on the terraces. They were also one of the products that They sold out more quickly in shops that remained active during the blackout. Why the stations continued to work. Augusto Molina and Héctor Zafra are respectively the technical director and the technical manager of the SER, and explained In a piece in this medium The way of proceeding in these emergency cases. The first thing they did was turn off monitors and all the teams that could be turned off to save to the fullest. That allowed maximizing the autonomy of emergency equipment that is used in these cases, and that were the key both in the SER chain and other stations. Electrogen equipment. These structure (motorogener) groups are machines that generate electricity through an internal combustion engine. They make use of fossil fuels (gasoline, diesel) and allow generating electricity while the fuel lasts. Are the teams that They are used in hospitals to maintain a good part of the essential services during this type of energy crisis. Several stations survived the blackout. National Radio of Spain kept for example emissions, such as They also did wave zero, the Cope chainthe aforementioned chain and other stations – although not all – and broadcasters who could continue to inform thanks to those emergency teams that were activated during the blackout. Radio as lifeguard in emergency situations. What happened yesterday has revealed the relevance of the radio as an ideal means of communication to emergencies. There have been numerous cases in the story in which that has become evident. In our country they stand out for example The coup d’etat of 23-F In Spain, in 11m or more recent attacks The Dana that ravaged the Valencian Community and that caused the majority of the electric laying. Transistors, both in one and another, allowed to remain informed.
