Vitamin D is well-known for supporting strong bones, but new research suggests it may also play a surprising role in slowing down the aging process itself. A new study published in The American Journal of Clinical Nutrition, reveals that daily vitamin D supplementation could help preserve telomeres—the protective caps at the ends of DNA strands—which naturally shorten as we age. Conducted by researchers at Mass General Brigham and the Medical College of Georgia, the reinforces anti-age studies indicating that the "sunshine vitamin" may slow biological aging at the cellular level.

Study Followed 1,000 People

The study, followed over 1,000 older adults in the US-men over 50 and women over 55. Participants were randomly assigned to receive either a placebo or a daily dose of vitamin D3 (2,000 IU) along with omega-3 fatty acids (1 gram). Telomere length in white blood cells was measured at the start, mid-point, and end of the study.

The results were striking. Compared to the placebo group, those taking vitamin D experienced significantly less telomere shortening—the cellular equivalent of aging three years more slowly. In contrast, omega-3 supplements did not have a significant effect on telomere length.

"Telomeres act like the plastic tips at the ends of shoelaces" explained study co-author Dr. JoAnn Manson, Professor of Women’s Health at Harvard Medical School. "They help protect our chromosomes from deterioration or fusion. As telomeres shorten with age, the risk of chronic diseases increases." This makes telomere length a powerful indicator of “biological age,” which may better reflect a person’s health status than chronological age alone.

Earlier results from the VITAL trial had already shown that vitamin D supplementation could reduce inflammation and lower the risk of advanced cancers and autoimmune diseases. Now, this new finding adds another layer of evidence in favor of vitamin D’s broader benefits for healthy aging.

“Our findings suggest that targeted vitamin D supplementation may be a promising strategy to counter the biological aging process,” said lead author Dr. Haidong Zhu, a molecular geneticist at the Medical College of Georgia. However, he emphasized that more research is needed to confirm whether these benefits apply across different populations and timeframes.

What Is Vitamin D Supplementation?

Vitamin D helps regulate the amount of calcium and phosphate in the body. These nutrients are needed to keep bones, teeth and muscles healthy. A lack of vitamin D can lead to bone deformities such as rickets in children, and bone pain caused by a condition called osteomalacia in adults. Government advice is that everyone should consider taking a daily vitamin D supplement during the autumn and winter.

People at high risk of not getting enough vitamin D, all children aged 1 to 4, and all babies (unless they're having more than 500ml of infant formula a day) should take a daily supplement throughout the year.

The best source of Vitamin D is sunlight. However, there are many food items through which you can get this essential nutrient. These include:

  • oily fish – such as salmon, sardines, trout, herring or mackerel
  • red meat
  • egg yolks
  • fortified foods – such as some fat spreads and breakfast cereals
  • liver (avoid if you are pregnant)

Ronald Acuña Jr. Sidelined with Achilles Tendon Tightness: What It Means and Why It Matters

Updated Jul 31, 2025 | 01:00 AM IST

SummaryRonald Acuña Jr. has been sidelined with Achilles tendon tightness, raising concerns about a potential serious injury. Know what Achilles tightness means, its risks, recovery process, and why even minor symptoms should never be ignored by athletes or amateurs.

It’s déjà vu Braves fans didn’t ask for. Ronald Acuña Jr., Atlanta’s powerhouse baseball outfielder and reigning National League MVP, has hit the injured list again, this time with tightness in his right Achilles tendon. Just months after returning from a torn ACL in his left knee, Acuña pulled up sore after sprinting the bases and later chasing a fly ball, exiting Tuesday’s game against the Royals mid-inning.

But what does Achilles tendon tightness actually mean, and why does it freak out athletes and sports doctors alike?

The Achilles tendon, also known as the calcaneal tendon, is the thick band of tissue that connects your calf muscles to your heel bone. It is the biggest and strongest tendon in the human body. But it can bring even the fittest athletes to their knees.

It helps you run, jump, pivot and push off the ground, basically every move an outfielder like Acuña makes in a single play. When it is tight, inflamed or partially torn, that springy propulsion becomes painful and unstable. Cue the limping, grimacing and, in some cases, weeks on the injured list.

Why Achilles Pain Is a Red Flag

Achilles tightness might sound like a minor complaint, but it is often the body’s early warning system. It could stem from overuse, fatigue, poor footwear, or biomechanical imbalances.

In Acuña’s case, the discomfort reportedly began the night before while sprinting around the bases and got worse chasing fly balls. That is a classic setup: high-intensity bursts, sudden stops, and quick direction changes, all high-risk moves for the Achilles.

If ignored, tightness can escalate to tendonitis (inflammation), partial tears, or the dreaded rupture, which is basically the tendon snapping in two. That is a season-ending injury, often requiring surgery and months of rehab.

When the Body Says No

Beyond the physical pain, repeated injuries hit hard on the mental game. Acuña admitted he did not want to sit out, even though the pain intensified, because he has already missed too much time.

But ignoring Achilles issues can backfire in the worst way. What starts as tightness today could be crutches tomorrow. The tendon does not heal fast, and re-injury is a very real risk if recovery is rushed.

The Game Plan for Recovery

For now, Acuña’s been placed on the 10-day injured list, but tendon issues do not always follow a schedule. He will likely undergo scans to rule out structural damage, followed by rest, anti-inflammatories, and physical therapy to stretch and strengthen the area.

Recovery is not just about waiting for the pain to stop; it is about rebuilding strength, restoring flexibility, and ensuring both legs are balanced and strong.

Why This Matters for Everyone Who Plays

This is not just a pro-athlete problem. Achilles injuries are surprisingly common in runners, dancers, and gym-goers. If you feel stiffness in your heel or lower calf, especially first thing in the morning or during exercise, do not brush it off.

Stretch regularly, warm up before activity, avoid sudden ramp-ups in intensity, and listen to your body. And if the pain lingers or worsens, see a specialist. Ronald Acuña Jr.’s Achilles flare-up might just be tightness, but it is the kind of tightness that turns trainers serious and fans anxious. It’s also a timely reminder that this tendon is small but mighty, and when it acts up, rest is not optional. Whether you are chasing fly balls or your morning run goal, treat your heels with the caution they deserve.

Manhattan Shooter Cited CTE in Suicide Note: Here Is What the Condition Means

Updated Jul 30, 2025 | 11:00 PM IST

SummaryA tragic Manhattan shooting has thrown light on CTE, a brain disease linked to repeated head trauma. Know what CTE is, its symptoms, who is at risk, and the growing concerns around its legal and medical implications.

A recent tragic shooting in Midtown Manhattan has pulled an obscure but alarming brain disease back into the headlines. The shooter reportedly left behind a suicide note claiming he suffered from CTE, short for chronic traumatic encephalopathy, a condition linked to repeated head trauma. As shocking as the incident was, it has opened up a floodgate of questions: What exactly is CTE? Can it really make someone act out violently? And how can we even know if someone had it?

What Exactly Is CTE?

CTE is not your everyday concussion aftermath. It is a progressive, degenerative brain disease caused by repeated head injuries, the kind you get from rough contact sports, military service, or just too many unfortunate falls. Over time, these impacts seem to trigger the buildup of an abnormal protein in the brain called tau. This sticky substance does not just sit there quietly. It gradually spreads through the brain, messing with vital functions and causing serious, irreversible damage.

The Symptoms

People with CTE do not wake up one morning knowing something is wrong. The symptoms can creep in slowly, subtle at first, then increasingly hard to ignore, leading to memory lapses, confusion, impulsive behaviour, unexplained aggression, mood swings, deepening depression and, in many tragic cases, suicidal thoughts.

It is the sort of change that can feel like a personality transplant. Loved ones often report seeing someone “become a different person” over time.

Not Just a Pro Athlete Problem

For a long time, CTE seemed to be the unwanted souvenir of retired American football players. The sport's culture of full-body collisions made it the perfect storm for head trauma. But recent research is telling a more disturbing story. A 2023 study uncovered CTE in younger, amateur athletes, including teens as young as 17.

Back to the Manhattan case. While the shooter’s note mentioned CTE, we still do not know whether he actually had it, let alone whether it influenced his behaviour. This brings up messy territory: should possible brain disease be considered in criminal responsibility? Can CTE be a mitigating factor in violent crime?

It is a grey zone. And until we develop reliable tools to diagnose CTE in the living, we are mostly left guessing.

What Can We Do?

CTE is a slow, silent thief, robbing people of their memory, emotions, and identity. And while scientists are racing to understand it better, prevention remains our best bet for now. That means:

  • Rethinking how we approach youth and professional sports
  • Reducing repeated head trauma wherever possible
  • Keeping an eye out for changes in behaviour following head injuries
CTE is not some mysterious ailment that only haunts linebackers. It is a very real, very scary consequence of repeated trauma to the brain, and as we are learning, it can touch more lives than we ever thought. It is time we start treating our heads with the same care we give the rest of our bodies, maybe even more.

What Is That One Thing That Makes Hepatitis So Dangerous?

Updated Jul 30, 2025 | 09:01 PM IST

SummaryHepatitis is deadly because it often shows no symptoms until severe liver damage occurs. Expert explains why early testing, vaccination, and public awareness are key to prevention. Breaking the silence around hepatitis can save millions of lives.

Hepatitis is not nicknamed the “silent killer” for nothing. What makes it so dangerous is how symptomless it often is for years. It can quietly chip away at your liver without so much as a warning sign. By the time symptoms like fatigue, jaundice, or abdominal pain appear, significant harm may already have occurred. This eerie silence allows hepatitis to go undetected until it has done some serious damage.

Just Because You Cannot Hear It Does Not Mean It Is Not There

Dr Vikram Vora says that hepatitis is a major global health threat, killing over a million people each year. What is even more tragic? These deaths are, in his words, “largely preventable”. The villains in this tale, cirrhosis and liver cancer, often stem from untreated or undiagnosed hepatitis infections.

Prevention Helps

“The cornerstone of hepatitis control is prevention,” Dr Vora says. And the good news is that you have got some powerful tools at your disposal. “Vaccination, especially against Hepatitis B, is one of the most effective tools available,” he says, adding that infants, healthcare workers, and at-risk adults should be prioritised. Other prevention measures include safe injection practices, steering clear of needle-sharing, and ensuring blood transfusions are properly screened.

But danger often hides in plain sight. Dr Vora warns that something as seemingly harmless as getting a tattoo or piercing can carry lifelong consequences if done in an unregulated facility. His advice? “Choosing safe, licensed establishments is non-negotiable.”

Why You Should Not Wait for Symptoms

If there is one thing hepatitis is good at, it is staying undetected. That is why Dr Vora champions regular screening, especially if you have had medical procedures, blood transfusions, or close contact with someone infected. “Early diagnosis is a game-changer,” he says. Caught in time, hepatitis can be treated effectively, helping patients avoid severe liver disease or even make a full recovery.

A Diagnosis Is Not a Death Sentence

Dr Vora offers hope to those living with hepatitis. “With proper medical care and lifestyle adjustments, a healthy life is achievable,” he insists. That means ditching alcohol, sticking to a balanced diet, maintaining a healthy weight, and closely following medical advice. He also points out the mental and emotional toll a diagnosis can take. “Support from family, community, and healthcare providers can make a significant difference in outcomes.”

The Stigma That Silences

Perhaps just as damaging as the virus itself is the social stigma surrounding it. Dr Vora identifies this as a major hurdle in tackling hepatitis. “Fear of social exclusion keeps many from seeking help,” he explains. And that delay can cost lives. According to him, building a culture of empathy and understanding is critical. He encourages public health campaigns, education, and open dialogue as essential tools to dismantle this stigma.

Make Noise Against the Silence

In Dr Vora’s words, “Hepatitis may be silent, but it is not invincible.” Every little step, whether it is getting vaccinated, getting screened, or just talking about it, can chip away at the power hepatitis holds. Silence has cost too many lives already. Awareness can save them.
