Veraverbeke, an Earth scientist at Vrije University in Amsterdam, the Netherlands, said the satellite had captured images of “zombie fires” – which are remnants of a great fire from the previous year. When people thought they had handled the fire, they still “survived” silently underground for a whole year, waiting through the winter to flare up again. Zombie fires have broken out many times over the past decades and tend to happen more and more often.

Mr. Veraverbeke’s team found that their occurrence is strongly linked to climate change. The fact that the summer is getting hotter and longer with a series of large fires increases the rate of spawning zombie fires. The proliferation of these “zombies” shows that the Arctic is changing rapidly under the influence of climate, and is a warning bell for more serious disasters in the future.

As summer approaches, fires formed by lightning strikes or humans will burn directly above the peat above ground. “ These are ancient soils. Peat in Siberia is really very old ,” said Jessica McCarty, an Arctic scientist at the University of Miami, Ohio. Once peat is ignited, they can provide a medium for a fire to smolder underground long after the surface fire is extinguished. Fires sustained by peat can burn for days, weeks, months, even years. When the right time comes, they will once again flare up into great fires, like undead zombies. “ Peat has everything a fire needs to sustain itself. Fires can burn quite strong enough to last through the winter. They’ll essentially ‘hibernate’ until next spring, when the snow melts and gives a chance for fires to flare up in the ground.” , said researcher Rebecca Scholten from VU Amsterdam.

From 2000 to 2010, fires consumed more than 50% of the Arctic every year. Over the next 10 years, the annual fire area continued to increase, especially in Alaska. Through the data, scientists found that the current frequency of fires in the Arctic is the highest since the first forest formed in this area about 3,000 years ago, maybe even the highest in 10,000 years. by. Wildfires in the Arctic produce more carbon than places like California or Europe, because the subsoil under high-latitude forests is often made up of old, carbon-rich peat. In 2020, the Arctic fires released nearly 250 megatons of carbon dioxide, about half the carbon emitted by humans in a year in Australia and about 2.5 times more than the record-breaking 2020 bushfires. in California. Climate Change Zombie fires have long been known to experts. In 1941, a man-made fire along a railroad in Alaska consumed almost everything within a 1,600 square kilometer radius around it. By May 1942, the fire “revived” and burned about 1,200 square kilometers. But scientists haven’t been able to determine whether these zombie fires are well documented, or if they occur more frequently as the Arctic climate warms rapidly. They think the second case is very likely. “ We’ll definitely see more of them (zombie fires) based on what I’ve seen in 30 years of observation and consultation (other experts) ,” said Randi Jandt, a fire ecologist at the University of Alaska, Fairbanks. Jandt cited the great fire that burned more than 10,000 square kilometers in Alaska in 2019. Fire crews had to work around the clock to prevent the fire from spreading. But when they thought the disaster was over, the fire flared up again the following spring, just as the snow had melted. “ Just now you observe that the area is completely white of snow, but only two days later, the fire suddenly broke out in that very place. ,” said Mark Parrington, a researcher at the Copernicus Atmospheric Monitoring Service, describing the 2020 zombie fire in Alaska. Mr. Parrington said the frequency of fires in recent years in Alaska, Siberia and northern Canada have all increased sharply. “ In the past, firefighting in the Arctic didn’t get much attention because fires were rare, but that’s changing rapidly.” , said researcher Parrington. Wildfires in the Arctic produce more carbon than places like California or Europe. (Photo: Esquire Middle East) Another concern is how many zombie fires are buried underground, waiting to create a new disaster. Scientists say underground fires in the underground peat layer grow very slowly, only about 100 times faster than hair, so the possibility that fires from many years are still accumulating under the ground can be ruled out. land. Therefore, researchers only study fires in the past year. However, the increasing severity of fires shows that climate change is making the situation worse. The hot summer produces large fires that burn until the end of the season, and remnants of those are more likely to last through the winter. In the North West of the Arctic, zombie fires typically flare up every six of the hottest summers. In the summer of the cooler years, no zombie fire will make it through the next winter. “ There is a clear relationship between zombie fires and high temperatures and fire zones. That relationship pattern is only likely to intensify for the worse in the future, as climate change increases the likelihood of fires in the Arctic. “, said scientist Scholten.

The first mass attack on Apple’s mobile platform came to light when researchers discovered 40 malicious apps that existed on the App Store. Apple was silent about the biggest attack on the iOS platform. Photo: Getty Images. When the scope of the investigation was expanded, this number was eventually determined to be 4,000. They contain malicious code that makes iPhone and iPad part of the botnet. Simply put, the iPhone infected with malicious code becomes the iPhone “zombie”, manipulated for many malicious purposes. Malware infiltrated 128 million iPhones This shocking information has just been revealed by Epic’s lawyers, a few days before the trial of the antitrust lawsuit between the game maker and Apple. Accordingly, on the afternoon of September 21, 2015, about a week after Apple launched iPhone 6s / 6s Plus, Apple leaders discovered 2,500 malicious applications on the App Store, which were downloaded by 128 million users, total plus 203 million visitors, of which 18 million users in the US. Thousands of malware appeared on 128 million iPhones. Photo: Bankinfosecurity. “Joz, Tom and Christine – the number of affected customers is very large, should we email all of them?”, Apple’s Senior Vice President of Global Marketing, Greg Joswiak team members by email. “If so, Dale Bagwell from the Customer Experience team will take care of it. It should be noted that it is difficult to translate emails into the local language, as the application is downloaded in many different countries around the world. About 10 hours later, Bagwell joined the discussion on this matter. Obviously localizing the content, especially the exact name of the application, is not easy. Finally, no emails are sent to the client. Apple quietly posted a simple Q&A document, which generally lists the series of malicious codes appearing on the App Store and the 25 most downloaded names of these. Currently the post has also been deleted. Malware impersonates Apple’s development tools The biggest attack in iOS history came from developers writing apps using fake Xcode – Apple’s iOS and OS X software development tools. The version called XcodeGhost stealthily inserted malicious code alongside the normal functions of the application. Since then, the infected applications cause the victim’s iPhone to be controlled and controlled by the server, and provide a lot of information about the device, including name, identification code, network information, details in ” IDfierForVendor ”… XcodeGhost has embedded the malicious code in popular applications. Photo: Hackread. In China, XcodeGhost promises to load faster than the Xcode toolkit provided by Apple. When developers use the fake version, they receive a warning from Gatekeeper, the macOS security feature requires the app to be verified by a reputable publisher. Eventually, however, thousands of apps developed from the fake toolkit still appeared on the App Store. Disappointing behavior of Apple According to the Wired The Cupertino giant has long made security and privacy a top priority on its devices. Therefore, they need to report directly to the users affected by this serious incident. Google has a bad reputation for being silent when users download malicious apps on Android or the Chrome browser, now it’s Apple’s turn. This is not the first malware scandal on the App Store that eventually falls silent. From 2013, page ArsTechnica found that the application “Jekyll” passed an Apple rating but ultimately contained malicious code. The leaders of Apple have forwarded back and forth, discussing a lot about the method of controlling and approving applications on the App Store. However, all are kept internally confidential without public notice to affected users. IOS 15 build with many new features The new iOS build integrates quite a few features that users have been waiting for.

Although Indonesia still ranks 5th globally in the number of ransomware attacks detected, it has dropped from 1,158,837 cases in 2019 to 439,473 cases in 2020. This downtrend also also appeared in other countries in the region including Vietnam, the Philippines, Malaysia and Thailand. China remains at the top of the list for the number of ransomware cases globally in both 2019 and 2020. Meanwhile, Brazil and Russia have swapped the 2nd and 3rd place in the rankings, with Brazil currently ranked 2nd by 2020. “When I look at the statistics for individual ransomware groups, I find that this trend is in line with an overall drop in the number of detected cases,” said Fedor Sinitsyn, security researcher at Kaspersky. This is mainly due to the decrease in the number of cases involving WannaCry. This group makes up a significant portion of all the ransomware discovered to date, although for more than three years these have not been supported by the “originator” and exist only as one. “zombie” “. One of the most persistent cyber threats facing small and medium businesses in the region is still ransomware, malicious code designed to infect the computers of organizations and individuals, and encrypting data. Data inside and block access to the computer. The attackers will then request a fee from the victim in exchange for re-activation of the system. Ransomware attacks may be on the decline, but Kaspersky has been warning businesses of all sizes in every sector about the increasing activity of Ransomware 2.0, also known as ransomware. have purpose. Mr. Yeo Siang Tiong, General Manager of Kaspersky Southeast Asia commented: “We should not be optimistic that the number of detected ransomware cases has decreased. Since last year, we have noticed a number of changes to this threat. The ransomware teams are now more concerned with quality than quantity. This means that instead of randomly and passively waiting for an unsafe user to bite, the attackers are now actively hunting for victims ”.

By Klaus-Rainer Jackisch, MR New money to stimulate the ailing economy is generated by the European Central Bank rather silently and unspectacularly. To combat the crisis, the central bank does not buy meters high paper or tons of paint to use to print new banknotes. Their delivery vans also do not transport cash from the catacombs of the Eurotower. And there is no printing press in the cellar that rattles, runs hot and steams vigorously. No, central bank money is usually created with a few clicks of the mouse on the computer – and in times of Corona even in the home office. The ECB thus produces book money, writes it in its books and distributes it on the markets.

Almost two trillion just for PEPP

1.85 trillion euros are generated almost incidentally in this way to combat pandemics alone. For this huge sum, the ECB buys bonds on the international financial markets in its PEPP program, which was set up especially for the coronavirus pandemic: government bonds, for example, with which the euro countries raise money for their budgets. Municipal bonds, the proceeds of which municipalities use to finance a new waterworks or the renovation of their town hall. And corporate bonds, which companies use to finance the development of new e-cars, economical washing machines or unusual chocolate creations, for example. Some of these bonds have excellent credit ratings and sell like hot cakes. You shouldn’t have others in your depot. The ECB will buy them anyway if they do not fall below certain criteria. The large amount of money that flows into the cycle is supposed to keep the economy going. It enables banks to lend companies cheaply so that they can continue to exist and hopefully expand again soon. Overall, it lowers interest rates because the central bank buys almost everything and the issuers can easily get rid of their bonds: So you only have to pay low interest. And finally, it provides the entire system with sufficient liquidity so that there are no bottlenecks. Since the financial crisis, the ECB, like other central banks, has seen bond purchases as a panacea for getting the economy going again. She didn’t really succeed. But at least the economy was able to recover a little for a while and did not slide down completely.

Risks and Side Effects

The side effects of this monetary policy are visible everywhere: the stock markets are exploding as if there is no tomorrow. Because of a lack of returns, the money flows to the stock exchanges. In the real estate markets, the home is becoming a barely affordable luxury property. After all, the sheer mass of liquidity also produces inflation in the long term, so it devalues ​​the money if it is not collected again in time. The first signs are already noticeable in real life. Another phenomenon that has so far received little attention is developing more in the dark. Experts call it the “zombization” of parts of the economy – a development that causes great damage in the long term and is likely to further reduce the level of welfare. The somewhat creepy term describes companies for which the large amount of cheap money from the ECB ensures their survival, although under normal circumstances they would have been bankrupt long ago. Either because your business idea is out of date or you cannot adapt to new circumstances. Or finally, because they are simply working inefficiently. So there are companies that can no longer pay their interest from current profits and would therefore have to file for bankruptcy. But given the current conditions, they can easily get more loans to service their interest.

Thousands of “zombie” companies in Germany alone?

The Cologne Institute of the German Economy estimates that around 5000 such “seemingly dead” companies have emerged in Germany alone in the wake of the pandemic. Their processing is also prevented because the obligation to report bankruptcy is currently suspended in this country. Worldwide, the share of such “zombie” companies is now around 18 percent, estimates the Bank for International Settlements in Basel (BIS), the central bank of the central banks and, so to speak, the mother of the entire central banking world. This value is the highest ever measured. Before the crisis it was twelve percent. This is partly due to the corona crisis. But the BIS experts have calculated that around 70 percent of these companies have no chance of getting back on their feet even without the virus. Instead, they would be artificially kept alive with the cheap money. The BIS has viewed this development with great concern for years. That is why it repeatedly calls on its members to end the loose monetary policy and return to reasonable interest rates. From an economic point of view, dragging sick and unproductive companies through is fatal in the long term because it lowers the welfare of societies and thus widening the gap between rich and poor.

Innovation slowed down, dynamism paralyzed

The structural problems of the European economy, which have at least been aggravated by the ECB policy, can be seen in bare figures: The productivity of workers in Europe has stagnated for years and continued to decline during the crisis. The number of start-ups, particularly in Germany, is also falling. In the land of inventors and inventors, the volume of patent applications is also stagnating. In fact, the monetary policy of the ECB is also causing economic dynamism in the euro zone to slacken because the “seemingly dead” companies are clogging the system. Because they occupy market areas and thus make it more difficult for new, innovative companies to enter. “Zombie” companies tie up capital, expertise and skilled workers that are lacking elsewhere in order to get new developments off the ground. The OECD has been warning of these developments for years and has repeatedly made it clear that Europe in particular is falling behind in global competition. Because in order to be able to keep up with an aggressive China and the self-conscious USA, functioning, dynamic economies are needed in Europe that are characterized by high innovative strength. Otherwise, they will not be competitive in the long run. However, this is exactly what the current monetary policy prevents.

ECB fears turbulence in the financial markets

The ECB is well aware of these connections. But when it comes to choosing between plague and cholera, it is better to stick to current politics. Even the appearance of a change in monetary policy immediately triggers unrest in the financial markets, as the rise in bond yields a few weeks ago as a result of higher inflation rates showed. The ECB is not primarily concerned with the welfare of the financial markets. But severe turbulence there always has very negative consequences for the real economy – especially for the labor market. ECB boss Christine Lagarde will probably also assure this week after the council meeting that the ultra-loose monetary policy will be continued. In fact, as announced in March, the pace of bond purchases has increased significantly in recent weeks. The ECB regards this monetary policy as a blessing. But how much it will become a curse for the economy in the long term will only be able to be assessed in years.

Researchers have gathered tissue samples from patients for brain research after death. Accordingly, the “zombie” gene may influence the study of brain-related diseases if the team prolongs the time to access the sample. The researchers analyzed gene expression from living brain tissue and found that in some cells, gene expression increased after death. They observed that inflamed glial cells develop and grow arm-like branches several hours after death. “Most research confirms that all activity in the brain stops when the heart stops beating, but not really,” said Dr. Jeffrey Loeb, Dean of the Department of Neurology and Rehabilitation at the University of Illinois Medical School. , Chicago. The “zombie” genes are activated after the brain stops working. They are glial genes responsible for attention to damaged brain tissue. Photo: Dr. Jeffrey Loeb / UIC. According to the Yourgenome.com Gene expression is the process of converting genetic information in DNA into functional products such as proteins or other molecules. “It’s not surprising that glial cells develop right after the heart stops beating. These cells become inflamed and their job is to clear things up after brain damage such as hypoxia or a sudden attack. Stroke, “Loeb said in a university press release. Also according to him, the connections are very remarkable. Most research uses post-mortem human brain tissue to find treatments for disorders like Autism, Schizophrenia, and Alzheimer’s disease. However, these studies did not take into account continuation of gene expression or cell activity. “Our findings will shed light on research on brain tissue in humans. It’s just that at this point, we haven’t yet quantified the changes,” said Loeb. Loeb is the director of UI NeuroRepository (at the University of Illinois), a bank that stores brain tissue, with consent, of patients with neurological disorders. Brain tissue is collected and stored when the patient dies or is in surgery. Not all brain tissue is needed to diagnose the disease, some of which is used for research. Loeb and his team noticed that the gene expression patterns in living brain tissue did not match any previous findings of brain tissue gene expression after death. Therefore, they conducted a simulation experiment to observe the expression of all genes in the human body 24 hours after death. As a result, about 80% of the genes maintain relative stability within 24 hours. These include genes that provide basic functions of the cell. Another group of genes, brain activity (such as memory, thinking, and seizure) quickly subsides within hours of death. A third group of genes – the “zombie” gene – became more active while the other groups of genes gradually decreased activity. During the first 12 hours of brain death, activity of the “zombie” gene peaked. “We found 1,427 genes clustered. A cluster of 317 rapidly depleted genes was predicted to be neuron and coincided with genes dependent on activity. The second cluster of 474 genes is predicted to be glia, consisting of astrocytes and microglia. Notably, due to the rapid decrease in the cluster of nerve cells, the glial cell cluster has significantly increased “, the scientists shared. These findings mean that researchers need to take these changes into account and minimize the time from death to study as much as possible to curb those changes that are too big, Dr. Loeb said. “The good news is that we know which genes and cells are stable, are decreasing, and which are increasing over time, which helps guide post-death brain research better,” he said. Therefore, naming the genes that are most active in the brain after death as “zombies” only makes this research more remarkable. This has nothing to do with the zombies in the sci-fi movies. Understanding the brain’s chemical signals is key to helping scientists find ways to cure brain-damaging diseases like Huntington’s chorea. This research was supported by an abundance of resources from the University of Illinois neuroscience archive, a collection of brain tissue samples with epilepsy and other ailments.

Snyder left his mark as a coincidental director also a work of zombie disaster. A remake of Dawn of the Dead and Zack really breathes new life into George A. Romero’s original epic. Since then, fans have been waiting for the director’s comeback, and it was not until May 2021 that everything came true. Army of the Dead will act as the spiritual successor to Dawn of The Dead, not a simple post-story.

As can be seen, from the new trailer, the zombies of Snyder have evolved in an amazing way. They are faster, smarter and more organized than the usual concept of a zombie.

While the upgraded zombies aren’t groundbreaking if you follow The Walking Dead, however, the twist at the end of the trailer has revealed that the zombie virus can even affect both animals and us. there was a “Tiger-zombie” growling in amazement from the survivors.

With Army of the Dead going to own a prequel movie, titled Army of Thieves, even if many characters will perish, fans still have peace of mind when their favorite role is likely. come back. Netflix seems quite confident in Snyder’s vision, with a rush to green light the prequel project when the movie is not hot.
