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?

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.

President Donald Trump's recent physical examination has been in the news, and now it is about a drug that was omitted in the test, which is making headlines. This very drug is raising questions about the health condition of President Trump, as he has been taking this drug for years. This medication is finasteride, a generic name for Propecia, which is a hair loss drug.

President Trump's recent test report at Walter Reed National Military Medical Center contains a list of drugs that he takes, but in that list, one important name was missing, and that is his hair loss drug, Propecia. According to The Washington Post, when they asked officials if the president still takes that drug, the White House said it was not obligated to reveal the full range of medications the president was taking.

The White House said, “The current report reflects all medications deemed clinically relevant to disclose at this time.” It added, “No additional undisclosed conditions or procedures materially affecting his health status were omitted from this report.”

Though even after the statement of the White House, experts are still questioning his health condition and the hair loss drug. Robert Klitzman, a psychiatrist who leads Columbia University’s master’s program in bioethics, said, “It raises significant questions of what else is possibly not being revealed.”

Steve Joffe, a physician and bioethicist at the University of Pennsylvania Perelman School of Medicine, said to the Post, “There’s a certain level of openness and disclosure that people have a right to expect from someone in whom they place such profound trust.”

President Trump's mysterious drug list, with many omissions, concerns experts as it lacks what matters the most.

Why is Trump's Boasting About Cognitive Test Score Making Experts Question?

President Donald Trump is saying that he has achieved a full score in a very difficult test. He said, “Unlike other US Presidents, none of whom have ever taken an approved, high difficulty, Cognitive Test, I scored a perfect 30 out of 30, considered ‘extreme intelligence.’”

“In fact, this is my fourth such test, all PERFECT or 120 correct answers out of 120 questions asked! Anyone rarely gets a Perfect Score, especially when achieved four times in a row.” He wrote in his post.

He also demanded that the candidates for president and vice president should also go through this kind of test by saying, “In fact, this is my fourth such test, all PERFECT or 120 correct answers out of 120 questions asked! Anyone rarely gets a Perfect Score, especially when achieved four times in a row.”

Why Did Experts Question Repeated Testing?

Trump’s claims were immediately questioned by experts like Dr. Jonathan Reiner and Abby Phillip of CNN. They argued that repeated tests may not provide the same value. According to them, as the president had taken the test several times and the questions didn't change that much, it was easy. Other than that, the test is not designed to calculate intellect; it is more of a dementia screening test.

The recent hantavirus outbreak aboard the luxury ship MV Hondius, which drew global attention and raised concerns about the potential for wider spread, has highlighted the need for better therapeutics and vaccines.

The outbreak claimed three lives and infected 13 people. While those affected recovered from the infection, they had contracted the Andes strain, which carries a risk of human-to-human transmission. There is currently no specific antiviral drug or vaccine for the Andes virus.

Now, researchers writing in The Lancet Infectious Diseases have reported early promising results for tocilizumab as a treatment for severe hantavirus pulmonary syndrome (HPS).

The researchers said tocilizumab warrants further evaluation as a treatment for severe hantavirus pulmonary syndrome.

What Did The Study Find?

The study is based on a case series involving 10 hantavirus patients treated at Hospital Zonal de Bariloche, Argentina, between June 1, 2024, and May 6, 2026.

Tocilizumab is an immunosuppressive medication used to treat severe inflammatory conditions, including severe COVID-19 and autoimmune diseases such as rheumatoid arthritis.

Researchers from San Carlos de Bariloche, Argentina, said that under an ethical framework allowing the emergency use of unproven medications outside clinical trials when no satisfactory alternatives exist, tocilizumab was administered to five eligible patients with laboratory-confirmed severe hantavirus pulmonary syndrome.

Five other patients received standard supportive care without Tocilizumab because they were too sick or the medication was unavailable when treatment was being considered. The case series represents the first descriptive report from a larger ongoing study.

Four of the five patients treated with Tocilizumab survived and were discharged from intensive care, whereas all five patients who did not receive Tocilizumab died shortly after admission to intensive care.

There is currently no approved vaccine or specific antiviral treatment for the Andes strain, underscoring the importance of further research into potential therapies such as tocilizumab.

However, the authors said, "the findings should not be interpreted as evidence for the implementation of routine use of Tocilizumab to treat severe hantavirus pulmonary syndrome, but they do support the need for urgent further research".

What Is Hantavirus?

According to the World Health Organization (WHO), hantaviruses are zoonotic viruses that naturally infect rodents and are occasionally transmitted to humans.

Globally, an estimated 100,000 to 200,000 hantavirus infections occur each year. The majority of cases are reported in Asia, particularly China. Most infections are sporadic or occur in small clusters linked to contact with infected rodents.

In humans, hantavirus infection can cause severe illness and death, although disease severity varies depending on the virus strain and geographical region.

Hantavirus Pulmonary Syndrome

Hantavirus pulmonary syndrome is a severe viral disease caused by the Andes virus, a type of hantavirus endemic in several regions of the Americas, including Argentina and Chile. In recent years, parts of Argentina have seen an increase in hantavirus cases.

The severe respiratory illness can rapidly become fatal. Reported fatality rates range from 20 per cent to 40 per cent, depending on the outbreak setting, quality of medical care, and surveillance capacity.

How Does Hantavirus Spread?

Hantavirus is primarily spread through contact with infected rodents, including exposure to:

• Urine
• Droppings
• Saliva
• Less commonly, scratches or bites from infected rodents

Unsafe food causes around 866 million illnesses and 1.5 million deaths annually, according to new estimates released by the World Health Organization (WHO) ahead of World Food Safety Day 2026.

The analysis warned that children aged less than five years face almost three times the risk of illness from unsafe food than older children and adults.

Children under 5 years of age experience 29 per cent of the health burden due to unsafe food, with 143,000 deaths in 2021, said the WHO. The global health body added that exposure to chemical hazards such as methylmercury and lead in food can harm the developing brain and cause lifelong neurological and developmental problems in children.

Foodborne diseases in children, particularly diarrhoeal diseases, can be deadly for this vulnerable age group.

“Food safety is not an abstract issue – it touches every meal, every family, every day. Unsafe food has always been a major public health concern, but until now we lacked the bigger picture of its staggering human and economic toll. These new estimates change that,” said WHO Director-General Dr Tedros Adhanom Ghebreyesus.

“For the first time, countries have their own data to see where the burden is highest. With that knowledge, governments can prioritize the actions needed to protect people’s health,” he added.

The WHO noted that exposure to biological hazards, including foodborne bacteria, viruses and parasitic infections, caused the majority of foodborne illnesses (approximately 860 million in 2021), while chemical exposures accounted for 73 per cent of deaths.

The new analysis significantly expands the evidence base by assessing 42 major foodborne hazards, including bacteria, viruses, parasites and chemicals, across 194 countries from 2000 to 2021.

The estimates now include new hazards such as metals, rotavirus and Trypanosoma cruzi, the parasite that causes Chagas disease.

Food can also be contaminated with chemicals such as inorganic arsenic, lead and methylmercury from natural sources and human activities.

The estimates revealed for the first time that dietary exposure to metals is increasing the burden of:

• Cardiovascular diseases
• Cancers
• Intellectual disability

Other risk factors include:

• Evolving diets
• Environmental pressures
• Globalization and inequalities in food systems.

Yuki Minato, WHO technical officer for food safety and senior author of The Lancet Global Health paper, noted that the analysis shows foodborne diseases are “being made worse by climate change, which increases contamination risks, and by antimicrobial resistance, which makes infections harder to treat”.

Yuki called for “a One Health approach – integrating human, animal, plant and environmental health” to save lives.

How To Prevent Foodborne Diseases

The WHO estimates that many food-related illnesses and deaths are preventable through measures including:

• Improved water quality
• Better sanitation and hygiene
• Food safety practices such as pasteurization
• Access to healthcare for vulnerable populations
• Keep clean
• Separate raw and cooked food
• Cook thoroughly
• Keep food at safe temperatures
• Use safe water and raw materials.
