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.

The US Centers for Disease Control and Prevention (CDC) has given a warning on having cosmetic surgeries in foreign nations, as it can cause serious infection, even in some cases, death.

CDC, in its report, has shed light on the fact that aesthetic surgeries such as breast augmentation, liposuction, and other elective procedures are performed both within the United States and abroad. This cosmetic enhancement is causing growing concern for public health.

CDC’s journal Emerging Infectious Diseases also published a study regarding the danger and fatality surrounding the beauty enhancement surgeries. This study screened over 2,100 reports of U.S. citizens who travelled in foreign nations between 2014 and 2024.

This CDC research identifies 21 reports involving approximately 145 patients who experienced severe adverse health effects after undergoing beauty enhancement procedures within and outside the US. Notably, four out of these patients even died due to having these surgeries.

The report also mentioned the reasoning behind this alert, as many of these clinics and facilities are causing infections and even death due to their outdated and careless infection-control practices, which include improper environmental cleaning, lack of use of personal protective equipment, a shortfall in hand hygiene, and repeated use of some surgical instruments.

Kiara McNamara, a CDC nurse epidemiologist and lead author of the study, said, “More and more people are getting medical procedures outside the United States, but there are risks.”

The CDC has urged U.S. nationals to research thoroughly before having cosmetic procedures in healthcare facilities abroad.

Norovirus Spreading Across the U.S.

The United States is once again witnessing a surge in norovirus infections, a highly contagious gastrointestinal illness that causes severe vomiting and diarrhea.

Media reports noted that hikers along Southern California's Pacific Crest Trail have been hit by a fast-spreading outbreak of what is often referred to as the "winter vomiting disease".

At least two dozen hikers have fallen ill along the trail over the past two weeks, resulting in at least one air rescue. Health officials believe the cases are linked to norovirus, USA Today reported.

In addition, the latest data from the US Centers for Disease Control and Prevention's National Respiratory and Enteric Virus Surveillance System also showed that norovirus cases have increased over several weeks following a sharp seasonal decline that began in March.

About 11.2 per cent of administered norovirus tests returned positive during the week ending April 28. That figure rose to 12 per cent in the week ending May 2.

Norovirus is commonly associated with the colder months, when respiratory illnesses such as flu and the common cold are widespread.

However, health experts note that late-spring increases in norovirus activity are not unusual, and outbreaks can occur throughout the year due to the virus's highly contagious nature, the report said.

President Donald Trump is boasting about his cognitive test score and claiming he has the highest score possible, but his comments on Truth Social have started a debate that questions the test itself.

President Trump is saying that he had a perfect score of 30 out of 30 in the cognitive test at Walter Reed National Military Medical Center, which, according to him, is a sign of “extreme intelligence.” On the other hand, experts are at odds with him in this regard, as the whole test is for screening cognitive function, not for calculating intelligence.

What Did President Donald Trump Say About His Cognitive Test Results?

The president 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.

Questions Raised Over Cardiovascular And Cholesterol Details

According to experts, the physical examination lacks detailed results from tests used to assess cardiovascular health.

Barbabella’s description of Trump’s cardiac health cites results from a coronary CT angiography, an echocardiogram, and an artificial-intelligence-enhanced electrocardiogram analysis.

Jonathan Reiner, Professor of Medicine and Surgery, Interventional Cardiologist, in a post on social media platform X, questioned the need for another coronary artery CT on Trump, as he was last scanned in October.

"We don’t typically scan patients 6 months later unless we are concerned about a finding on the initial scan. What prompted the repeat CT?" he said.

Further, Trump’s cholesterol numbers and medication regimen also attracted attention from physicians who reviewed the memorandum.

According to the report, his HDL (good cholesterol) level was 70 mg/dL, while his LDL (bad cholesterol) level was 53 mg/dL.

The report said Trump takes rosuvastatin and ezetimibe for cholesterol management.

“He’s got like the best cholesterol numbers you’ll see,” said Daniel Torrent, adding that it is unusual for medication alone to achieve such favorable values. “We don’t usually manage people to the point where they’re that good.”

Wastewater Data Shows Rising Activity

According to data from WastewaterSCAN, a Stanford University-led program that tracks disease activity through wastewater testing, norovirus activity was "high" and on an upward trend nationwide in late May.

The surveillance data showed norovirus was detected in 100 per cent of samples collected during May, with concentrations particularly high in the Northeast and Midwest regions of the country.

What Is Norovirus And Its Common Symptoms?

Norovirus causes viral gastroenteritis, sometimes called “stomach flu” or a “stomach bug,” though it isn’t related to influenza. As per Mayo Clinic, it consists of several strains of RNA viruses that inflame the stomach and intestines, causing nausea, vomiting, and diarrhea.

Symptoms usually appear one to two days after exposure and often include:

• Nausea
• Vomiting (non-bloody)
• Watery diarrhea
• Stomach cramps
• Dehydration (rare but possible)
• Fever
• Headache
• Body aches

Most people recover within one to three days, though they can still spread the virus for up to two weeks after feeling better.

Who Gets Norovirus?

Anyone can get infected. Norovirus is the leading cause of acute gastroenteritis in the US, affecting all ages. Young children, older adults, pregnant people, and individuals with existing health conditions are more vulnerable.

How Does Norovirus Spread?

Norovirus spreads very easily. It survives well in the environment, and only a minuscule amount is enough to infect someone. In fact, just a few particles on the head of a pin can infect over 1,000 people.

Exposure can happen through:

• Eating contaminated water or food, especially leafy greens, fresh fruit, and shellfish like oysters
• Contact with vomit or fecal particles from someone who is infected, either by touching them directly or by touching contaminated surfaces, utensils, or toys.
