MRI scans are strong diagnostics with high-definition images of what lies inside a body. Strong magnetic fields require precaution, as brought out by an instance where a young woman suffered very serious injuries due to an oversight in a metallic core within a silicone sex toy that she happened to have before the MRI scan. This makes a stark reminder about the potentially deadly consequences of missing metal objects when such procedures are being performed. In April 2023, a 23-year-old woman went into an MRI with a silicone plug containing a metal core that was not known.

She thought that the item is made entirely out of silicone according to the advertising. However, the strong magnetic field of the MRI machine interacted with the hidden metal, dragging the object through her body and causing excruciating pain. According to reports from the U.S. Food and Drug Administration (FDA), the scene was harrowing, with the woman screaming in agony and requiring immediate hospitalization. Despite pre-scan screenings, which are routine prior to a scan, the patient did not inform the facility that the object existed because he presumed it was purely non-metallic. This caused serious injuries that led to the patient's law suit against the manufacturer for deceitful misrepresentations of material content.

MRI machines employ magnets between 0.5 to 3 Tesla (T). This is thousands of times stronger than the Earth's magnetic field. The tremendous force causes ferromagnetic materials, like iron and nickel, to be magnetized quickly and become strongly attracted toward the magnet. Objects as small as hairpins or paper clips will accelerate at 40 miles per hour inside the magnetic field.

The force can lead to catastrophic injuries in items lodged within the body, such as metallic implants or foreign objects. Metallic cores within devices, like pacemakers or intrauterine devices, must be disclosed to radiologists to prevent such complications.

How Metal Objects Interact with MRI Fields?

On these claims, Dr. Adam Taylor, a specialist in human anatomy, weighed his words in a international health website and added that the distance away and mass of this object would increase its velocity towards that of sound, "The acceleration would be phenomenal, but with a metallic core, it can't go anywhere near supersonic speeds. As for the size, the magnetic acceleration to the internal soft tissues would ensure that there could be severe intracranial trauma."

The injuries inflicted in this case likely involved damage to major blood vessels, nerves, or organs, highlighting the devastating impact of even minor oversight during an MRI scan.

This is not an isolated case. There are documented cases of metallic objects causing serious damage during MRI scans with a 65-year-old man with schizophrenia swallowed metal objects, including sockets and a hinge pin. The powerful magnetic field during an MRI scan caused the objects to rupture his stomach, resulting in serious injuries.

A toddler who ingested 11 small magnets perforated his bowel while undergoing a scan, making his case unique. In another deadly but extremely rare incident, there have been people who hide a firearm on themselves during MRI procedures. Magnetic attraction can trigger a discharge in a weapon and has led to some fatal injuries.

These cases emphasize the very strong need for adequate screening and patient education prior to an MRI.

Preventing MRI-Related Incidents

Medical professionals have been trained to avoid risks. This is by properly screening a patient for metallic objects. In general, most pre-scan protocols include:

• Patients are interrogated about implants, recent surgery or exposures at work related to metals.
• Radiologists sometimes use handheld metal detectors to search for hidden items.
• People who work with metal, like welders or machinists, will need additional testing to detect microscopic metal fragments within soft tissues or eyes.

The case emphasizes the importance of product labeling by manufacturers, especially those products that are likely to unintentionally cause harm to health. The patient's assumption that her device was 100% silicone points to a larger problem in consumer markets with misinformation.

It also reminds the patients to report any possible dangers to the medical professionals, no matter how the objects look non-metallic. In sensitive cases, patients can request private discussions with healthcare providers to ensure safety without discomfort.

In the end, it is a joint effort from manufacturers, healthcare professionals, and patients that can prevent such tragedies. Manufacturers must ensure truthful marketing, while healthcare providers should educate patients about the dangers of metal objects in MRI settings. For patients, understanding the risks and actively participating in pre-scan disclosures can be lifesaving.

This young woman's experience is a sobering example of the unforeseen dangers posed by MRI machines when precautions are overlooked. It serves as a wake-up call to address gaps in patient awareness, medical protocols, and product transparency. By learning from this incident, the medical community and the public can work together to ensure MRI scans remain a safe and effective diagnostic tool.

Aedes aegypti mosquitoes that spread dengue, chikungunya and Zika are showing resistance to permethrin, a commonly used pyrethroid insecticide, in parts of Pune, according to a new ICMR-National Institute of Virology (NIV) study.

The finding, published as preprint in the International Journal of Tropical Insect Science, raises concerns about the effectiveness of insecticide-based mosquito control, particularly during outbreaks.

Researchers collected Aedes aegypti mosquitoes from nine Pune Municipal Corporation wards — Pashan, Susgaon, Khadki, Yerawada, Warje, Hadapsar, Kondhwa, Kothrud and Dhankawdi — between February and May 2024.

They exposed the mosquitoes to 0.75% permethrin, the standard dose used in WHO susceptibility testing.

Resistance was detected in mosquitoes from six of the nine localities, while mosquitoes from three wards remained susceptible.

Genetic Mutations Linked to Resistance

The researchers then used PCR amplification and Sanger sequencing to look for genetic changes associated with pyrethroid resistance.

They identified four previously reported mutations:

• S989P and V1016G in Pashan and Kondhwa
• F1534C in Khadki, Susgaon, Warje, Yerawada and Hadapsar
• T1520I exclusively in Hadapsar

The D1763Y mutation, which can occur alongside V1016G, was not detected. The differences in mutations across wards suggest that resistance mechanisms may vary between mosquito populations.

Why Are Mosquitoes Becoming Resistant?

Pyrethroid resistance can develop through metabolic changes, target-site mutations, or both. Target-site changes, known as knockdown resistance (kdr) mutations, can reduce the ability of pyrethroids to act on the mosquito's voltage-gated sodium channel.

Pyrethroids have been widely used in India for mosquito control since the 1980s. Reduced susceptibility to deltamethrin, lambda-cyhalothrin and permethrin has also been reported in several states, including Assam, Delhi, West Bengal and Rajasthan.

The researchers noted that the widespread use of pyrethroid-based household mosquito-control products, including vaporizers, mats and coils, could potentially contribute to resistance.

What Does This Mean for Public Health?

According to the WHO South-East Asia Region Epidemiological Bulletin which reported 22,938 dengue cases in India through June 2026.

When mosquitoes develop resistance, more of them can survive exposure to insecticides that would normally kill susceptible mosquitoes. This could make controlling Aedes aegypti more difficult, particularly during dengue outbreaks.

Importantly, insecticide resistance does not mean the mosquitoes cause more severe dengue. The concern is that commonly used mosquito-control measures may become less effective.

The researchers called for regular resistance surveillance, insecticide rotation and locally tailored integrated vector-management strategies.

Did Insecticide Spraying Cause the Resistance?

The researchers noted that areas reporting more dengue cases may have experienced more frequent insecticide spraying, which could potentially be associated with higher resistance.

However, the study did not directly track insecticide use in these areas and did not establish that spraying caused the resistance.

The researchers stressed the need for continued surveillance to track resistance and adapt mosquito-control strategies to local conditions.

Future research could examine resistance genes through genetic mapping, transcriptomic profiling and CRISPR-Cas9 studies, while studying behavioral changes that may help mosquitoes survive insecticide exposure.

Cancer cases linked to the September 11, 2001, World Trade Center terror attacks have surged 75%, according to new research, highlighting the ongoing health crisis even 25 years later.

The research was conducted by Northwell Health’s Long Island Jewish (LIJ) Medical Center, which provides free medical monitoring to people affected by the aftermath of the attacks at New York’s World Trade Center, where nearly 3,000 people were killed.

About two-thirds of all enrollees are certified for at least one WTC-related health condition, while 30% of those enrolled through Northwell have battled cancer. That number is expected to rise dramatically over the next decade.

“For over 25 years, we have cared for people who were exposed to the aftermath of September 11th,” said Jacqueline Moline, director of the Northwell WTC Health Program.

“Over 57,000 cases of cancer have been documented, and cancer rates — including rare cancers — are rising. There has been a two-fold increase in lung cancer in just five years. Our fear is that cancer diagnoses will only rise as we move into the next 25 years.”

Which Cancers Are Growing?

Northwell’s WTC Health Program saw 9/11-certified cancer cases increase from 177 in 2023 to 235 in 2025 — a 75% jump over three years.

Another 132 new cases were reported through the first half of 2026, continuing the trend. That brings the total to 811 new cases over 42 months.

Prostate and skin cancers were the most common, followed by breast and urinary tract cancers.

By comparison, the program recorded 1,634 cancer cases during the first decade from 2013 to 2022, and 2,445 all-time cases through June among 1,489 people.

Crisis Grows From Lung Diseases To Cancer

Researchers at the center noted that September 11 was not a one-day event. The toxic dust cloud at Ground Zero and the gruelling recovery work created a persistent environmental catastrophe that continues to affect lives.

A variety of lung diseases were seen earlier among those affected. Now, after a decades-long incubation, a range of cancers is emerging as a growing concern.

"Hundreds of thousands of people were at risk then and remain at risk for disease now. While we initially saw respiratory disease, we now are faced with increasing numbers of our patients developing cancer," Moline said.

Further, a trove of newly released files by New York City Mayor Zohran Mamdani indicates that toxic air persisted for months after the 9/11 attacks on the World Trade Center and that officials played down the health risks.

“People got sick because the leaders they trusted lied and told them they were safe to breathe in toxic air,” Mamdani said at a news conference with survivors.

“As the years pass and the human toll grows, we reckon with the cost of September 11th whenever another New Yorker is stolen from us too soon. Now, close to 25 years later, more people have died from 9/11-related illnesses than were killed on the day itself.

Google DeepMind has launched AlphaGenome Atlas, an AI-powered database that maps the predicted effects of all 9 billion possible single-letter changes in the human genome.

The novel tool could help scientists identify genetic changes linked to rare diseases, understand how mutations affect gene function and uncover new clues about human health and disease.

AlphaGenome Atlas: Explore DNA We Don’t Understand

Scientists have a strong understanding of the roughly 2% of the genome that codes for proteins. But interpreting mutations in the remaining 98% of non-coding regulatory DNA has been much more difficult.

Changes in these regions can disrupt how genes are regulated and affect cellular functions. By pre-computing the predicted effects of billions of genetic variations, AlphaGenome Atlas aims to give researchers a map for navigating this largely unexplored part of the genome.

The resource could help researchers investigate unsolved rare diseases, uncover biological mechanisms behind common illnesses and support drug discovery.

One Score to Help Researchers Prioritize Variants

The Atlas introduces the AlphaGenome Variant Impact (AVI) score, a single score that combines predictions for genetic effects across coding and non-coding regions.

This allows researchers to prioritize potentially important variants without having to sift through thousands of individual data points.

Each AVI score is also linked to the biological features contributing to the prediction, including aspects of gene regulation predicted by AlphaGenome and protein-impact information from AlphaMissense.

A Genetic Database

AlphaGenome Atlas contains predictions for the effects of 9 billion single-nucleotide variants in the human genome.

The dataset is about 1 petabyte in size, making it more than 30 times larger than the previous AlphaFold Database.

The Atlas brings together several resources, including:

• Molecular effect predictions: Thousands of predictions for each variant across multiple aspects of gene regulation, covering hundreds of human and mouse cell types and tissues.
• AVI score: A single score indicating the predicted impact of each genetic variant.
• AVI feature attributions: Information showing the biological features driving each AVI score.
• DNA sequence motifs: A collection of more than 2,500 recurrent DNA sequences and their locations in the genome.

One of the biggest challenges in rare disease research is identifying the few potentially causal variants among thousands of genetic changes.

Researchers at the Broad Institute, working with the GREGoR Consortium, used the AVI score to prioritise variants in unsolved rare disease cases and identified a variant affecting the DNM1 gene which is strongly linked to epileptic encephalopathy.

Finding Genetic Links To Complex Traits

AlphaGenome Atlas is also being used to study rare, non-coding variants linked to complex traits, where the large number of harmless genetic changes can create substantial statistical noise.

Researchers at the University of Exeter applied the Atlas to identify 22% more non-coding genetic associations.

Among the top 1% of variants predicted to have the greatest impact, the analysis identified 19 genetic regions linked to body mass index (BMI), helping direct further targeted research.

AlphaGenome Atlas Is Free For Research

Google DeepMind said AlphaGenome Atlas is being made free to the scientific community for academic research, with the aim of opening new pathways for genetic and biomedical discovery.

The company described it as a comprehensive catalogue of how genetic mutations are predicted to affect molecular biology, covering every possible single-letter genetic change across the human genome.
