Many of us believe that we are great drinkers and that alcohol does not affect us as much. People who are able to drink without showing any sign of inebriation are known as social drinkers. In short, they are not addicted to alcohol but will not turn down the opportunity to have a good time! While it may seem like it doesn’t affect you, new studies suggest that it is just an illusion, even if you have high tolerance, alcohol affects your cognitive and motor functions more than you think.

The study reveals the below implications and techniques:

  • Researchers used a new MRI technique to precisely measure brain electrical activity.
  • By comparing brain scans before and after drinking, scientists identified specific areas affected by alcohol and how much brain activity slowed down.
  • Participants were chosen to be regular social drinkers without alcohol addiction, ensuring the study focused on the effects of alcohol alone.
  • MRI technology provided reliable data on brain activity changes caused by alcohol consumption.

How does the brain react to alcohol?

The human brain is a complex network of billions of neurons that communicate through electrical impulses. Brain conductivity refers to the efficiency with which these electrical signals travel through brain tissue. It's akin to the speed and clarity of a digital signal through a wire. In layman terms, your brain must function in its peak condition as it is essential for various cognitive processes, including memory, attention, decision-making, and motor control.

Think of it as the foundation for your brain's performance. When brain conductivity is high, information flows smoothly, and that helps your brain in rapid processing and response. On the other hand, low conductivity can hinder cognitive function, leading to slower thinking, impaired memory, and difficulties with coordination.

A study conducted at the Neuroscience Research Australia (NeuRA) and UNSW Science unveiled a startling connection between alcohol consumption and brain conductivity.

What is the connection between alcohol consumption and brain activity?

While many people brush off the effects of alcohol as temporary changes in behaviour, the reality is much more complex. Beyond the obvious impacts on coordination and judgment, alcohol significantly alters brain function. Alcohol dramatically slowed down brain activity, especially in areas responsible for decision-making, planning, and physical coordination. This decline was so significant that it resembled the brain changes seen in normal ageing. This means even one drink could temporarily accelerate the ageing process of your brain.

Alcohol and Brain activity: What does the study Imply?

The implications of this research are far-reaching. It provides compelling evidence that alcohol consumption has a direct and measurable impact on brain function. The discovery that alcohol can significantly reduce brain conductivity opens new avenues for understanding the neurocognitive effects of alcohol abuse and dependence. While you may not feel like alcohol is affecting you and you have a high tolerance, it most definitely changes and affects your decision-making abilities and impulse control.

Furthermore, the MRI technique employed in the study could be a valuable tool for assessing the impact of other substances on the brain and for developing interventions to mitigate alcohol-related brain damage.

American Cancer Society Revises Prostate Cancer Screening Guidelines: What You Need To Know

Updated Nov 13, 2026 | 06:00 PM IST

Summary​Updated for the first time since 2010, the guidelines, published in CA: A Cancer Journal for Clinicians, introduce age- and risk-based screening schedules. They aim to detect potentially aggressive cancers while limiting unnecessary tests and treatment.

BidenAmid rising prostate cancer cases, the American Cancer Society (ACS) has revised its screening guidelines, recommending earlier testing for men at higher risk to improve early detection.

Prostate cancer is the most common cancer among men after skin cancer and the second-leading cause of cancer deaths among men in the US. An estimated 333,830 men will be diagnosed and more than 36,000 will die from the disease in 2026.

Updated for the first time since 2010, the guidelines, published in CA: A Cancer Journal for Clinicians, introduce age- and risk-based screening schedules. They aim to detect potentially aggressive cancers while limiting unnecessary tests and treatment.

Former President Joe Biden urged men to get tested for prostate cancer after the American Cancer Society changed its screening guidelines, four days after he said his own fight with the disease has been slowing him down.

"I know firsthand the toll of this disease, and I know that catching it early saves lives. So talk to your doctor, get screened, and let’s keep working to end cancer as we know it," Biden shared in a post on X.

What Has Changed In The New Screening Guidelines?

Previously, the ACS recommended that men discuss the benefits and risks of screening with their doctors without prescribing a specific schedule.

The revised guidelines recommend prostate-specific antigen (PSA) blood tests at different intervals based on age and risk.

1. Men At Average Risk: Ages 50–69: PSA testing every two years.

2. Men At Higher Risk

Black men:

  • Begin screening at 45, with annual PSA testing until age 69.
Non-Black men with a family history:

Men with an affected father, brother or son should begin screening at 45 and continue through age 69.

  • Annually: If a close relative was diagnosed before 65, or more than one close relative has had prostate cancer.
  • Every two years: If only one close relative was diagnosed at 65 or older.

Men with inherited genetic risk:

Men with inherited conditions such as BRCA2 mutations, or those with a close relative carrying a high-risk mutation who have not been tested, should discuss screening with their doctor.

3. Screening After Age 70

  • Ages 70–74: Discuss the benefits and risks with a doctor. Those opting for screening should undergo PSA testing every two years.
  • Ages 75–79: Screening is not routinely recommended. Exceptionally healthy men with rising PSA levels may discuss continuing with their doctor.
  • Age 80 and above: Screening is discouraged.

Screening is also not recommended at any age for men in poor health who are not expected to live another 10 years.

What Happens If Your PSA Level Is High?

An elevated PSA does not necessarily mean prostate cancer or an immediate need for a biopsy. The ACS considers PSA levels high at:

  • 3 ng/mL or higher in men younger than 70.
  • 6.5 ng/mL or higher in men aged 70 and above.

If elevated, the test should be repeated, preferably within two weeks to three months. If levels remain high, further evaluation may include:

  • Prostate MRI: To identify suspicious areas.
  • Biomarker testing: To assess cancer risk.
  • Prostate biopsy: To confirm cancer when indicated.

These additional steps can help avoid unnecessary biopsies and reduce screening-related harms.

Active Surveillance For Low-Risk Prostate Cancer

For men diagnosed with low-risk prostate cancer, the ACS recommends active surveillance as the initial management approach. This involves:

  • Regular PSA testing.
  • Periodic biopsies.
  • MRI scans, when appropriate.

Treatment may be considered if monitoring shows that the cancer is becoming more aggressive.

Prostate Cancer: Why Early Screening Matters?

"Early prostate cancer usually doesn't cause signs and symptoms, which is why screening is important," said Dr. William Dahut, chief scientific officer at the ACS.

When symptoms occur, they may include:

  • Difficulty urinating or a weak urine stream.
  • Frequent urination, particularly at night.
  • Blood in the urine or semen.

Advanced prostate cancer may cause bone pain if the disease spreads to the bones or other organs.

However, these symptoms can also indicate conditions other than cancer. Men experiencing them should consult a doctor.

India has intensified its efforts to eliminate tuberculosis (TB) through early detection, advanced diagnostics, nutritional support and community participation under the Pradhan Mantri TB Mukt Bharat Abhiyaan, launched in September 2022, the Union Health Ministry said.

Citing the WHO Global Tuberculosis Report 2026, the ministry said India recorded a 38% decline in TB mortality since 2015, outperforming the global reduction of 35%. The country also achieved a 94% treatment success rate among patients with drug-susceptible TB.

TB Mukt Bharat Abhiyaan: 15 Lakh Asymptomatic Cases Detected

The campaign has expanded its screening efforts through intensified 100-day campaigns, including initiatives launched on December 7, 2024, and March 24, 2026.

Between December 7, 2024, and November 8, 2026, more than 25 crore people were brought under TB screening activities.

According to the ministry, the screening drive resulted in:

  • More than 11 crore chest X-rays conducted.
  • Over 3 crore nucleic acid amplification tests (NAAT) conducted.
  • 48.64 lakh TB cases detected, including 14.97 lakh asymptomatic cases.

"The detection of nearly 15 lakh asymptomatic cases is particularly significant, demonstrating the effectiveness of proactive screening in identifying individuals who might otherwise remain undiagnosed. Early identification facilitates timely treatment and provides opportunities to reduce TB transmission and prevent severe disease," the ministry said.

How The Intensified TB Screening Campaign Works

The first intensified 100-day campaign was launched on December 7, 2024, across 347 high-priority districts in 33 states and Union Territories. It was subsequently expanded nationwide to strengthen early detection, particularly among vulnerable and high-risk populations.

A second intensified 100-day campaign, launched on March 24, 2026, focused on screening in 1.58 lakh high-risk villages and wards, congregate settings and vulnerable populations.

Technology And Innovation In TB Diagnosis And Care

The campaign uses chest X-rays and rapid molecular diagnostic tests to identify and diagnose TB cases. Portable AI-enabled digital X-rays and other technology-enabled tools have also been deployed to strengthen screening and diagnosis.

  • AI-enabled X-rays: Portable digital X-rays supported by artificial intelligence help strengthen screening and early detection.
  • Rapid molecular testing: Nucleic acid amplification tests (NAAT) enable faster TB diagnosis.
  • Ni-kshay digital platform: Supports patient tracking, treatment monitoring and programme management, helping ensure continuity of care.
  • Comorbidity screening: TB screening is integrated with the identification and management of diabetes, undernutrition and other comorbidities.

What Happens After TB Detection?

The campaign focuses on prompt treatment initiation, differentiated patient care, nutritional assistance and continued community-based support to improve treatment outcomes.

Through the Ni-kshay Poshan Yojana, eligible patients receive financial assistance towards their nutritional requirements during treatment. The Ni-kshay Mitra initiative encourages individuals, institutions and organisations to provide nutritional and psychosocial support.

The ministry said 67,933 panchayats were declared TB-free in 2025, reflecting efforts to involve communities in India's TB elimination programme.

India Records 38% Decline In TB Mortality

According to the WHO Global Tuberculosis Report 2026, India's estimated TB mortality rate declined from 28 per lakh population in 2015 to 18 per lakh in 2025, representing a 38% reduction.

The country also recorded a 94% treatment success rate among patients with drug-susceptible TB.

The government said 96% of the TB programme's funding requirements are being met through domestic resources.

What Is Viral Heightmaxxing? US Doctors Warn Teen Boys Against Taking Cancer Drug To Grow Taller

Updated Nov 13, 2026 | 02:00 AM IST

SummaryTeenage boys in US are reportedly using black-market erdafitinib, a prescription cancer drug, in an attempt to grow taller as part of the viral "heightmaxxing" trend. Doctors warned that the drug is not approved for height growth and can cause serious side effects, including vision damage, metabolic abnormalities and skeletal complications.

Several viral social media trends promoting physical appearance and self-improvement have raised health concerns, with some encouraging potentially dangerous practices.

One such trend, known as "heightmaxxing", has prompted warnings from doctors after reports emerged of teenage boys taking black-market cancer drugs in an attempt to grow taller.

Aolescents are reportedly experimenting with erdafitinib, often referred to online as "ERDA" or "Erta", a prescription drug approved to treat advanced bladder cancer. The trend appears to have gained traction following online discussions suggesting the medication could increase height.

"It's extremely concerning that teenagers are experimenting with powerful cancer medications in an attempt to grow taller," Dr. Stephanie Widmer, a New York City-based emergency medicine physician, told Fox News.

"These drugs were developed to treat serious medical conditions, not to enhance physical appearance, and taking them without a legitimate medical indication or physician supervision can have devastating consequences," Widmer added.

In a statement to magazine Rolling Stone, drugmaker Johnson & Johnson emphasised that erdafitinib has never been approved to stimulate height growth and that its safety and effectiveness have not been established in children or adolescents.

Can Erdafitinib Actually Increase Height?

Medical research has documented unexpected growth spurts in children receiving erdafitinib for brain tumours. A 2024 study published in Hormone Research in Paediatrics described accelerated growth in two paediatric patients.

A separate case report documented a teenager who grew more than five inches during treatment but also developed serious skeletal complications.

However, doctors caution that these unexpected growth spurts do not necessarily indicate healthy skeletal development.

Dr. Jessica Gray, a family physician in Lubbock, Texas, warned that rapid, drug-induced growth could trigger dangerous structural problems, including premature growth plate damage and bone fractures, Fox News reported.

Widmer noted that height is largely determined by genetics and that there are no shortcuts to increasing it. Once the growth plates close towards the end of puberty, medications cannot reopen them. This means older adolescents taking erdafitinib could face serious health risks without any prospect of gaining height, she said.

"One of the biggest concerns is that these medications can cause serious side effects, including potentially permanent vision damage, elevated phosphate levels and other metabolic abnormalities," Widmer said.

"We're talking about adolescents whose bodies are still developing, and exposing them to these risks for a cosmetic goal is particularly troubling."

Erdafitinib works by blocking specific cellular signalling pathways involved in cancer cell growth. These pathways also play a role in bone development, which may help explain the unexpected growth observed in some paediatric patients.

Other reported side effects include skeletal pain, particularly in the hips or knees, mouth sores, loose nails and skin disorders.

What Should Parents Do?

Doctors advise parents to watch for unusual joint pain or unexplained physical changes and speak openly with their children if they suspect they are using medications obtained online.

Teenagers concerned about their height or growth should consult a paediatrician rather than experiment with prescription drugs.

"We should be encouraging teenagers to prioritize their health, not teaching them to gamble with it," Widmer said. "No amount of additional height is worth risking permanent damage to your vision or other serious and potentially unknown medical complications."
