New study confirms 5G is safe: No harm found in human cell exposure
In a significant breakthrough for public health and technology debates, a new study from Germany's Constructor University has found no harmful effects of 5G signals on human cells, even under extreme exposure conditions. Tired of too many ads? go ad free now By directly exposing human skin cells to high-intensity 5G electromagnetic waves, scientists concluded that there were no changes in gene expression or DNA methylation, both crucial indicators of cellular health. These findings offer the strongest evidence yet that 5G technology, despite ongoing conspiracy theories, does not pose a biological risk to humans when used within standard safety limits. Scientists test 5G at full strength To thoroughly assess 5G's safety, researchers intentionally exposed two types of human skin cells, fibroblasts and keratinocytes, to frequencies of 27 GHz and 40.5 GHz, which fall within the high-frequency millimetre-wave spectrum of 5G. These exposure levels were significantly higher than those typically encountered in real-world scenarios, simulating the most extreme possible conditions. What is the impact of 5G on DNA or gene activity After exposing the cells for durations ranging from 2 to 48 hours, the researchers found no measurable changes in gene expression or DNA methylation patterns. These two metrics are considered reliable indicators of how cells respond to environmental stress. Their unchanged state strongly suggests that 5G exposure does not trigger harmful cellular responses, even when pushed beyond standard safety thresholds. Penetration depth: Too shallow to harm One of the key reasons 5G is biologically safe, according to the study, is the limited penetration depth of high-frequency electromagnetic waves. Frequencies above 10 GHz only penetrate the skin up to 1 millimetre, meaning they do not reach deeper tissues or organs. Tired of too many ads? go ad free now This physical barrier significantly reduces the likelihood of any systemic biological effects. Heating effects ruled out While earlier studies suggested that radio frequencies might cause tissue heating, this research carefully controlled for temperature. The scientists ensured that any observed effects would be non-thermal, and still found no evidence of harm. This directly counters concerns that 5G may cause biological disruption without heating tissue. Closing the debate on 5G health risks By simulating worst-case scenarios and still finding no negative effects, this research offers a decisive answer to a long-standing question. The scientists hope their findings will help dispel fear and misinformation surrounding 5G, especially regarding so-called 'invisible dangers.' While concerns about screen time and overall device usage remain valid, the radiation from 5G itself appears to be safe.

Is 5G harmful to humans? Scientists finally test it by blasting human cells with 5G waves
There are many conspiracy theories. And one of them is that 5G is harmful to birds, and if it is harmful to birds then it is probably harmful to humans and their brain. Now, a recent study is giving a clear answer to this question. Do 5G signals pose danger to human health? The answer is: no, they do at Germany's Constructor University recently conducted research and came to conclusion that '5G-exposed human skin cells do not respond with altered gene expression and methylation profiles'. advertisementDuring this research the scientists directly exposed human skin cells to high-intensity 5G electromagnetic waves. And the results were reassuring. Published in PNAS Nexus, the study puts an end to the ongoing debate over the potential health risks of 5G see the impact of 5G waves, researchers used two types of human skin cells — fibroblasts and keratinocytes — and exposed them to frequencies of 27 GHz and 40.5 GHz, which fall within the higher-end spectrum of 5G signals. These higher frequencies are part of the millimetre-wave bands expected to be widely deployed in the near future. According to the study, "even under worst-case conditions, no significant changes in gene expression or methylation patterns are observed after exposure."'We wanted to simulate worst-case exposure conditions,' the researchers were quoted as saying in reports. They also deliberately applied electromagnetic fields significantly stronger than what is permitted under international safety guidelines. According to the study, the exposure times ranged from two to 48 hours, simulating both short-term and prolonged contact with 5G the research points out that there were no detectable alterations in gene expression or DNA methylation. Notably, both gene expression and DNA are key indicators of cellular health and function. According to the study, frequencies up to 3 GHz can penetrate about 10 millimetres into the skin, while those at or above 10 GHz barely reach beyond 1 millimetre. This according to the researchers makes any deep biological interaction extremely is to be noted that researchers have already found that high-intensity radio frequencies can cause tissue heating. However, this research was conducted in a controlled environment to rule out temperature-induced effects. The conclusion: if there is no heating, there is no harm. The study challenges the claim that 5G exposure might cause non-thermal biological effects. 'Our data casts fundamental doubt on the existence of non-thermal biological effects from 5G exposure,' noted the research this study, the researchers hope to 'close this debate' with hard evidence and help the public better understand how electromagnetic radiation works within safe parameters. However the broader concerns about screens and wireless devices still remain, as these can impact mental and physical well-being in more subtle ways.

Scientists Blasted Human Cells With 5G to See What Would Happen
More research has confirmed that, no, there is no evidence your cell phone will compromise your health. The recent study specifically analyzed electromagnetic waves used by 5G networks, which, during the pandemic, were at the center of conspiracies linking the technology to covid infections. In an effort to finally 'close this debate,' researchers from Constructor University blasted two types of human skin cells with 5G electromagnetic fields significantly stronger than recommended safety limits for periods of two and 48 hours. Their results indicate that permissible levels of 5G electromagnetic waves do not damage human skin. 'These results will contribute to counteracting the uncertainties with well-founded facts,' the researchers wrote in a study published Tuesday in PNAS Nexus. Devices such as cell phones can send and receive information through methods like Wi-Fi and cellular data. These wireless transmission networks transmit data via electromagnetic waves within specific frequency ranges. As more data travels through these networks, however, these frequency ranges can become congested—and, as a result, slower. This is why 5G networks, which use new radio frequencies compared to older 4G networks, were introduced in 2018. Currently, 5G networks operate on frequencies below 6 gigahertz. In the next couple of years, 5G will also operate on frequencies from 24.3 to 27.5 GHz and 39.5 to 43.3 GHz, according to the study. While that might sound scary, electromagnetic waves up to 3 GHz penetrate the skin at a depth of just about 0.39 inches (10 millimeters), while waves at or higher than 10 GHz remain even more superficial, reaching at most 0.039 in (1 mm) deep. Nevertheless, 'widespread adoption of 5G wireless technology and the imminent introduction of higher frequencies have intensified public concerns regarding its potential health effects,' the researchers explained. The few, isolated studies fueling these concerns 'have faced criticism for methodological shortcomings, including lack of blinding, temperature control, and transparent statistical methods.' Blinding is when information that could influence the results of a study is hidden until the end. In the recent study, which was blinded and temperature-controlled, researchers exposed two types of human skin cells, called fibroblasts and keratinocytes, to 5G electromagnetic waves at 27 and 40.5 GHz frequencies with varying levels of intensity. Ultimately, their 'results show with great clarity that in human skin cells, even under worst-case conditions, no significant changes in gene expression or methylation patterns are observed after exposure.' DNA methylation patterns are a biological mechanism that control, among other things, gene expression. It's worth pointing out that high-intensity radio frequencies—the kind used in most wireless networks—can heat biological tissues. In fact, the researchers point out that frequencies above 6 GHz, when applied at intensities far exceeding safety reference levels, can cause heat-related damage. In this study, however, the researchers conducted temperature-controlled experiments to 'cast fundamental doubt on the existence of possible nonthermal biological effects of exposure.' In other words, any impact not related to heat. This study adds to a growing body of evidence showing that 5G cell phone signals do not pose a health risk to humans. If anything, our greater concern should be the impact of ever-increasing screen time on our well-being.

Study debunks 5G health conspiracy theory (again)
Conspiracy theories about cell phone towers and wireless communication have existed as long as the technologies themselves. But in an age of rampant disinformation, objectively false claims about these subjects are more widespread than ever, and increasingly difficult to combat. Take 5G cellular service, for example. The more advanced network's unfortunately timed 2019 rollout made it the focal point in many off-the-wall COVID-19 conspiracies. While some of the more ludicrous claims involved 5G microchip implants hidden in fake vaccines, others fell back on a more familiar trope—that 5G frequencies are actively harmful to our health. Studies have repeatedly debunked these claims in the past, but researchers at Germany's Constructor University recently decided to provide more evidence that our smartphones aren't secretly poisoning us. What's more, their study published in the May issue of the journal PNAS Nexus showcases just how innocuous 5G's electromagnetic fields really are. Cellular networks operate and transmit information within predetermined frequency ranges. All 5G networks currently operate under 6 gigahertz (GHz), but that will expand to encompass 24.3 to 27.5 GHz and 39.5 to 43.3 GHz ranges in the coming years. While very strong electromagnetic fields can potentially cause physiological damage, the frequencies used in 5G can't penetrate the body beyond a few millimeters of skin. Despite this, the team from this study conducted a fully blinded experiment that exposed human cells to not only 5G frequency ranges, but also far more powerful electromagnetic fields. The team focused on two kinds of human skin cells: fibroblasts and keratinocytes. These make up connective tissue and the majority of the epidermis, respectively. Over a series of tests, the researchers exposed the sample cells to 27 and 40.5 GHz frequencies at multiple strengths for both two and 48 hour intervals. According to the authors, this is the first-known study to use methods including whole-genome RNA sequencing and methylation array for analyzing both the genetic and epigenetic effects of 5G frequencies on human cells. The results were about as predictable as could be expected. Even at 10 times the recommended exposure limits, the team did not find a single change to gene expression or methylation profiles beyond what can be expected from chance. The authors also made sure to note that although a handful of previous studies offer contrary claims, those experiments did not control for temperature. Because of this, it's extremely likely that any of their recorded 'effects' from 5G exposure were the results of heat alone. '[O]n the one hand [our results are] very well in line with biophysical facts: at the frequencies tested here, the quantum energies are far too low to have photochemical or even ionizing effects,' the authors wrote in their conclusion. 'On the other hand, it shows how important it is to precisely control, document and, if necessary, compensate for the temperature effects caused by the exposure.' The researchers hope their latest findings will 'close this debate' on 5G, particularly any claims to 'possible nonthermal biological effects of exposure.' Given the state of global misinformation, however, the chance of these and similar conspiracy theories disappearing for good is about as unlikely as a 5G microchip lurking inside your next COVID-19 booster shot.
