Pope Francis injured his right arm after suffering a fall earlier this week. According to the Vatican, while the 88-year-old pontiff did not break his arm, a sling was put on as a precaution. This incident comes just weeks after another fall on December 7, where he hit his chin on a nightstand, resulting in another, visible bruise. The pope's health has been a topic of ongoing speculation due to his age and medical history, which includes long bouts of bronchitis and mobility challenges. Often seen using a wheelchair or a cane, Francis also uses a walker within the Vatican's Santa Marta hotel, where he resides. Notably, his frailty has brought renewed attention to the risks of falls among elderly individuals and the steps one must follow to mitigate such falls.

Preventive Measures For Bone Health

A study published in Frontiers in Aging Neurosciences people get older, the bone density in the lower back and thigh bone decreases significantly. This raises the risk of osteoporosis (OP). Therefore it becomes pivotal to pay early attention to nutrition, exercise ability, vitamin D levels, and uric acid levels in older individuals to prevent Ostreopsis and mitigate fall risks. The risk of falls and bone injuries among elderly individuals underscores the importance of preventive measures for maintaining bone health and minimizing fall risks.

Elderly, particularly menopausal women, require a daily calcium intake of 1,200 mg, divided into two or more doses. This can be achieved through dietary sources such as dairy and non-dairy products or through supplements like calcium carbonate and calcium citrate. However, total daily calcium intake should not exceed 2,500 mg to avoid potential health risks.

Vitamin D is essential for calcium absorption and bone mineralization. While sunlight exposure helps synthesize vitamin D, older individuals often require supplements due to reduced skin synthesis and the limited availability of foods. Fortified milk and supplements containing 200–600 IU of vitamin D daily are recommended, with higher doses required for those with deficiencies. Severe cases may necessitate high-dose treatments, such as 50,000 IU weekly for up to three months, along with regular monitoring of calcium and vitamin D levels.

Regular exercise is vital for preserving bone mass and reducing fall risk. Weight-bearing activities, strength training, and balance exercises like brisk walking or skipping can enhance bone density and improve coordination. Experts recommend at least 30 minutes of moderate physical activity most days of the week, supplemented by strength training twice weekly. For individuals unable to engage in standard exercise routines, alternatives like vibrating platforms may help maintain bone health.

Falls remain a leading cause of fractures among individuals over 60. Addressing contributing factors such as balance issues, vision problems, and environmental hazards can significantly reduce risks. Preventive measures include regular vision checks, minimizing medications causing dizziness, improving home safety (e.g., installing railings and removing loose rugs), and wearing rubber-soled footwear. Hip protectors may also help mitigate the impact of falls.

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.
