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.

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.

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.

Artemis Hospitals, Medulance launch 5G-connected ambulance in Gurugram
NEW DELHI: Artemis Hospitals on Wednesday partnered with the emergency ambulance care provider, Medulance , to launch a 5G-connected ambulance in Gurugram. Artemis and Medulance, in a joint statement, said the ambulance will enhance emergency care , especially in cases like heart attacks, strokes, or traumas, by harnessing the strengths of fifth-generation ( 5G ) connectivity, artificial intelligence (AI)-driven diagnostics, and real-time telemedicine. With 5G, important vitals such as heart rate, oxygen levels, and blood pressure can be sent from the ambulance to the hospital instantly, allowing for quick and informed care. The ambulance with 5G and AI keeps an eye on and analyses patient data in real time. AI finds patterns and informs paramedics about important changes so they can act quickly. This smart integration turns the ambulance into a ' mobile emergency room (ER)," which means that decisions can be made and life-saving actions can be taken on the go before the patient reaches the hospital. Citing research, the companies said that in India, an estimated 24,012 people die daily due to delays in receiving medical assistance. A study by AIIMS and ICMR earlier found that only 10.8% of patients reached appropriate health facilities within the critical first hour of symptom onset. 'This initiative will set a new benchmark for emergency care in India, ensuring that every patient receives timely and accurate care, no matter where they are. In a country where millions of lives are lost due to delays in medical treatment, this technology is a game-changer,' said Devlina Chakravarty, MD, Artemis Hospitals. 'This initiative represents a leap forward in emergency medical response. By integrating the speed and reliability of 5G, we're able to provide real-time, data-driven medical assistance, drastically improving patient outcomes,' said Vishal Arora, chief of business transformation & operational excellence, Artemis Hospitals. 'Medulance is proud to partner with Artemis Hospital to launch a 5G-enabled advanced ambulance, marking a milestone in our shared commitment to transforming emergency healthcare in India,' said Pranav Bajaj , co-founder & CEO, MedulanceHealthcare.

Is Calgary's tap water safe again? Why a controversial mineral is making a splash again
After over a decade without fluoride in its drinking water, Calgary is set to reintroduce the mineral into its municipal supply beginning June 30, 2025. This follows a 2021 plebiscite in which 62 per cent of Calgarians voted in favour of resuming fluoridation to support better dental health outcomes. Calgary stopped fluoridating its water in 2011, citing aging equipment and concerns over cost. However, since then, health professionals have noted a rise in tooth decay, especially among children. Studies suggested that Calgary residents, particularly lower-income groups, were facing worsening dental health outcomes. In response to the growing evidence and public demand, city officials put the matter to a vote in 2021, resulting in a clear mandate to bring fluoride back. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Melhore a performance da sua frota [Clique] Sistema TMS embarcador Saiba Mais Undo How will it be implemented? After extensive retrofitting and construction, fluoride will be added at two upgraded water treatment plants, Glenmore and Bearspaw. The reintroduction project cost the city $28.1 million, and the anticipated annual maintenance cost is around $1 million. Live Events The city aims to maintain fluoride levels at 0.7 milligrams per litre, the standard recommended by Health Canada to prevent tooth decay. Given the natural fluctuations in fluoride content in the Bow and Elbow rivers, water quality will be closely monitored and adjusted accordingly. Broader health and regional impact Alberta Health Services , the Canadian Dental Association, and the World Health Organization endorse fluoridation as a safe, effective public health measure. It will also impact surrounding communities like Chestermere, which rely on Calgary's water supply. This decision aligns Calgary with other Alberta cities such as Edmonton, Lethbridge, and Red Deer, which have continued fluoridation without interruption. In contrast, two weeks ago, Florida became the second state in the US, after Utah, to ban fluoride in public drinking water. It stated that adding forced fluoride into the water supply is forced medication on people. Social media's support, skepticism, and satire The reintroduction has sparked a flurry of social media commentary, with reactions ranging from cautious approval to deep skepticism. Some residents welcomed the move, saying Calgary's water quality has long needed improvement. Others, however, expressed concern over perceived health risks. Several users referred to fluoride as a 'neurotoxin' and shared videos urging people to invest in home filtration systems. One user quipped, 'Time to invest in water filtration stocks in Alberta,' another warned of 'random poisoning' and advised switching to healthy water or filters with UV attachments. Conspiratorial tones also emerged, with claims about fluoride affecting the pineal gland and interacting with 5G frequencies. Still, a few commentators simply saw it as a practical decision overdue for a growing city. What comes next? City officials say residents won't notice any difference in taste or smell, but long-term oral health outcomes are expected to improve. As the system is phased in, regular updates will be provided through Calgary's official channels.
