Microwaves are a common appliance in every household now. You will see it in kitchens of not just houses, but offices, cafeterias, and co working space. However, there are studies that show that heating food in a microwave could be a health concern. While it does come handy, there are questions about harmful radiation and nutrient loss and heating safety that still linger.
Some research suggests that microwaving may cause nutritional loss, particularly in vegetables. For example, studies have shown that microwaving broccoli with water diminishes its flavonoid content, which are anti-inflammatory compounds. However, experts note that cooking method and duration have a significant influence on nutrient retention.
Surprisingly, several studies indicate that microwaving preserves more nutrients than traditional cooking methods. A study comparing microwaved versus oven-cooked ready meals found that the microwaved version contained somewhat more vitamin C. Another study discovered that microwaving some vegetables, such as broccoli and green beans, may retain more beneficial compounds than boiling.
Ultimately, the nutrient loss really vary on the type of food which is being heated and how it is being cooked. Experts also recommend using minimal water and shorter cooking times to maximize the nutrient retention.
Plastic containers and heating food in it, has always been a topic of debate. While containers do come with microwave-safe stamps, is it really safe to heat them with food?
According to research, when certain plastics are subjected to heat, they produce compounds such as phthalates and bisphenol A (BPA). These substances have been associated to hormonal disturbance, metabolic problems, and perhaps reproductive concerns.
A study also took in account over 400 plastic food containers that were microwave-safe and found that most of them leaked hormone-disrupting chemicals. These are phthalates, warn experts, which are commonly used in food packaging and can interfere with body's hormonal balance, and increase risk of diabetes or even high blood pressure.
Additionally, BPA exposure has been associated with fertility issues and immune system disruptions.
To minimize this risk, experts recommend using glass or ceramic container when microwaving foods. If you must use a plastic container, make sure the container is not damaged or old, as they are more prone to leach harmful chemicals.
Concerns about microwave radiation have been largely debunked by decades of research. Microwaves use non-ionizing radiation, which does not have enough energy to damage DNA or cause cancer. The electromagnetic waves used in microwaves are similar to those from radios and light bulbs.
Experts emphasize that microwave ovens are designed to contain radiation, preventing exposure. As long as the microwave is in good condition and the door seals properly, there is no significant health risk from microwave radiation.
Microwaving food could sometimes also lead to uneven cooking and it can create some risks to food safety. Thus, experts advertise to use microwave only to reheat the food and not to actually cook raw food. For safe reheating, food should reach at least 82°C (176°F) throughout to kill bacteria.

Prime Minister Narendra Modi today launched the nationwide Human Papillomavirus (HPV) vaccination campaign for girls aged 14 years from Rajasthan's Ajmer.
The initiative marks a decisive step towards eliminating cervical cancer through timely HPV vaccination. Cervical cancer remains the second most common cancer among women in India. Nearly 80,000 new cases and over 42,000 deaths are reported annually in the country.
"Today, I have had the opportunity to launch the HPV vaccine campaign from Ajmer. This campaign is an important step towards empowering women and daughters of this country,” PM Modi said.
“For us, this was a sensitive issue tied to the insult of our sisters and daughters, one that made them ill. That is why we resolved it at a crucial turning point in their mission,” he added.
The World Health Organization has also lauded India's mission to launch the HPV vaccine and prevent the risk of cervical cancer.
“We are leaving no stone unturned to ensure that the daughters of the country are healthy and prosperous. The objective of this initiative is the prevention of cervical cancer," the Prime Minister, earlier wrote in a post on social media platform X.
The nationwide program, based on expert recommendations of the National Technical Advisory Group on Immunization (NTAGI), will target girls aged 14 years.
At 14, the HPV vaccine offers maximum preventive benefit, well before potential exposure to the virus.
"By prioritizing prevention at the right age, the program is expected to provide lifelong protection and significantly reduce the future burden of cervical cancer in the country," the government said.
“The HPV vaccine works best at 9-14 years, before exposure, and when the immune response is strongest. Studies show effectiveness is highest in younger age groups and decreases with age,” Dr. Parmod Kumar, Associate Professor in Medical Oncology, AIIMS Jodhpur, shared on X.
Vaccination under the national program will be voluntary and free of cost.
The HPV vaccination will be conducted exclusively at designated government health facilities, including Ayushman Arogya Mandirs (Primary Health Centers), Community Health Centers, Sub-District and District Hospitals, and Government Medical Colleges.
Despite being preventable, cervical cancer continues to claim the life of a woman every two minutes globally, and the WHO South-East Asia Region bears nearly one-quarter of the global burden.
Dr. Catharina Boehme, Officer-in-Charge, WHO South-East Asia, stated that the introduction of HPV vaccination at a national scale in India "will have a far-reaching impact". It will accelerate progress not only for the country, but for the region and the world, she said.
“This landmark step, led at the highest level of government, reflects India’s strong commitment to protecting adolescent girls from cervical cancer," said Dr. Boehme.
With today’s milestone, nine of the 10 countries in the Region now include HPV vaccination in their national immunization programs.
The WHO global targets for 2030 include vaccinating 90 percent of girls by age 15, screening 70 percent of women by ages 35 and 45, and ensuring 90 percent of women with pre-cancer and invasive cancer receive appropriate treatment.

As we grow older, it is almost expected that memory will fade. Names slip. Dates blur. Thoughts take longer to form. Inside the aging brain, proteins can misfold and clump together, damaging cells and gradually eroding cognition. But not everyone follows this script.
Some people reach their 80s with memory and mental sharpness that rival those decades younger. Scientists call them “super-agers.” Now, new research published in Nature offers a possible explanation for why some brains hold up so remarkably well.
At the heart of the findings lies one of neuroscience’s most contested questions: can adult human brains grow new neurons?

For years, scientists have debated whether neurogenesis, the birth of new neurons, continues into adulthood. While it is well established in babies and young children, and in many animal species, evidence in adult humans has been mixed.
This new study adds weight to the idea that it does continue, even into advanced age.
Researchers examined brain tissue donated after death from several groups: younger adults with normal cognition, older adults with typical memory for their age, people with mild cognitive impairment, individuals with Alzheimer’s disease, and super-agers over 80 whose memory functioned like someone about 30 years younger.
They focused on the hippocampus, the brain’s memory hub and a region long suspected to be a birthplace for new neurons.
To detect neurogenesis, scientists looked for three types of cells: neural stem cells, neuroblasts, and immature neurons. In simple terms, stem cells are like infants, neuroblasts are adolescents, and immature neurons are on the brink of adulthood.
“We identified genetic markers for three key types of cells,” the researchers explained, tracing the pathway from stem cell to developing neuron.
All groups showed signs of these cell types. The difference lay in the numbers.
Super-agers had roughly twice as many new neurons as older adults with typical memory, and about two and a half times more than those with Alzheimer’s disease. In fact, their hippocampi contained even more immature neurons than the brains of younger adults.
“This paper shows biological proof that the aging brain is plastic,” Tamar Gefen told The New York Times. She added that this adaptability appears to persist “even into a person’s 80s.”
The immature neurons in super-agers also carried distinctive genetic and epigenetic signatures. According to Gefen, as quoted by The New York Times, “Super-aging happens not only because there’s more of these young cells, but because there is a type of genetic programming” that allows them to survive and resist age-related decline.
In other words, it is not just about quantity. It may also be about resilience.
The Alzheimer’s findings were equally intriguing.
People with Alzheimer’s actually had more neural stem cells than other older adults. But they had far fewer neuroblasts and immature neurons. This suggests that while the starting material was present, the developmental process stalled.
One interpretation is that neurogenesis becomes disrupted in Alzheimer’s. Stem cells may remain dormant, unable to mature into functioning neurons.
“If that’s true, that’s really opened up a new direction for the field,” Hongjun Song told The New York Times, suggesting that reactivating these dormant cells could one day become a therapeutic strategy.
It is an exciting possibility. Instead of only trying to prevent damage, scientists might be able to encourage regeneration.
The neurogenesis debate is far from settled.
Some researchers argue that methodological differences have led to conflicting conclusions over the years. Shawn Sorrells, who studies neurogenesis, told The New York Times that mapping how the hippocampus changes in people who age differently is “fantastically interesting and important,” but he cautioned that the findings should be validated using additional techniques.
Skepticism remains because detecting new neurons in adult human brains is technically difficult. Results often hinge on the markers and imaging tools used.
Even if this study does not end the debate, it opens new doors. If certain people naturally maintain robust neurogenesis into their 80s, researchers want to understand why. Is it genetics? Lifestyle? A combination of both?
Scientists are now exploring whether the special properties seen in super-agers’ immature neurons can be replicated or supported through medication or other interventions.
The bigger takeaway is hopeful. Aging does not necessarily mean inevitable cognitive collapse. The brain may retain more capacity for renewal than once believed.
If neurogenesis truly persists across the lifespan, the story of brain aging may need rewriting. Instead of focusing only on decline, researchers may increasingly look toward regeneration and resilience.
And for anyone worried about forgetting where they left their keys, that possibility feels quietly revolutionary.

Do you know that congenital hypothyroidism, a rare disability, affects about 1 in 2,500–3,000 newborns globally, but in India, the incidence is higher -- approximately 1 in 1,000 births.
India records nearly 26 million births annually, with an estimated 10,000 babies born each year with Congenital Hypothyroidism.
This means 27 babies are born every day in India, with the condition that more than one is born every hour. Early treatment within the first 2 weeks of life can ensure normal brain development, while delayed treatment can reduce IQ by 30–50 points.
Congenital Hypothyroidism (CH) is a condition present at birth in which a baby’s thyroid gland does not produce enough thyroid hormone.
The thyroid is a small gland located in the neck. It produces a hormone called thyroxine (T4), which is essential for brain development, growth, and overall body metabolism. The thyroid hormone is especially important in the first few weeks of life.
The thyroid hormone helps in:
If a baby does not receive enough thyroid hormones soon after birth, it can lead to permanent intellectual disability and growth problems.
The good news is that congenital hypothyroidism is easily detectable and completely treatable if identified early.
What Causes Congenital Hypothyroidism? What Are The Symptoms?
Congenital Hypothyroidism may occur because:
One of the biggest challenges with Congenital Hypothyroidism is that most babies look completely normal at birth.
However, over time, some signs may appear:
How Is Congenital Hypothyroidism Detected?
1. Newborn Screening Test (Heel-Prick Test)
2. Confirmatory Blood Tests
If the screening test is abnormal, the doctor will order:
3. Thyroid Scan
In some cases, imaging tests are needed. The ultrasound of the neck (less accurate) and Nuclear Medicine Thyroid scan (more accurate) may be done to check whether the gland is absent, small, or misplaced. However, treatment should not be delayed while waiting for imaging.
When Should Treatment Start?
Treatment should begin as early as possible -- ideally within the first 14 days of life. Starting treatment within the first two weeks allows normal brain development.
Delaying treatment increases the risk of permanent intellectual disability.
Doctors will monitor:
Initially, blood tests are done every 2–4 weeks, then less frequently as the child grows. Proper follow-up ensures the dose remains correct. Some babies may need treatment for life.
In certain cases, doctors may reassess thyroid function after 3 years of age to see whether the condition is temporary or permanent. Most children who receive early and proper treatment grow up with completely normal intelligence and physical development.
Can Congenital Hypothyroidism Be Prevented? Why Early Screening Is So Important
Most cases cannot be prevented. However:
A baby with Congenital Hypothyroidism may look perfectly healthy. Without screening, diagnosis may be delayed until symptoms appear—by then, brain development may already be affected.
With early testing the diagnosis is simple; treatment is affordable; and outcome is excellent. But without testing:
Congenital Hypothyroidism is one of the most preventable causes of intellectual disability in children. A small heel-prick test in the first few days of life can protect your baby’s brain forever.
If you are expecting a baby or have a newborn, speak to your doctor about newborn thyroid screening.
Early diagnosis. Simple treatment. Normal life.
