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.

Artificial Intelligence can fast-track better diagnostics, and even a cure for Alzheimer’s Disease, said OpenAI CEO Sam Altman.

In an exclusive interview with TODAY, Altman also announced that the OpenAI Foundation is pledging $100 million to Alzheimer’s research.

“AI has the potential to dramatically speed up how we discover treatments, improve diagnostics, and hopefully get us closer to a cure,” he said.

“This is one of the hardest problems in medicine - and one that affects millions of families. We felt we could help accelerate progress,” Altman added.

OpenAI Commits $100 Million For Alzheimer’s Research

Alzheimer's disease is one of the most common forms of dementia, causing 60-70 percent of cases. It mostly affects adults over the age of 65 and is a leading cause of death and disability.

In a statement, OpenAI noted that Alzheimer’s is "one of the toughest problems in medicine".

"AI’s ability to reason across complex data could help researchers uncover new insights," it added.

The company will partner with six research institutions to

• support and accelerate Alzheimer’s research
• generating new data,
• helping design new drugs,
• expanding possible paths to treatment, including repurposing existing FDA-approved molecules.

“The OpenAI Foundation’s Alzheimer’s research initiative represents more than scientific progress. It’s a hope for millions of people, families, and anyone concerned about brain health. We applaud bold investments that prioritize speed and rigor, because every day matters. We must accelerate breakthroughs that change what it means to live with, or be at risk for, Alzheimer’s," said Joanne Pike, President and CEO of the Alzheimer’s Association.

What Is Alzheimer’s Disease?

Alzheimer's disease is believed to be caused by the development of toxic amyloid and beta proteins in the brain, which can accumulate in the brain and damage cells responsible for memory.

While there is no clear cause of Alzheimer's disease, experts believe it can develop due to genetic mutations and lifestyle choices, such as physical inactivity, unhealthy diet, and social isolation.

Early symptoms of Alzheimer's disease include forgetting recent events or conversations. Over time, Alzheimer's disease leads to serious memory loss and affects a person's ability to do everyday tasks.

There is no cure for this progressive brain disorder, and in advanced stages, loss of brain function can cause dehydration, poor nutrition, or infection. These complications can result in death.

About 8.8 million Indians aged 60 and above are estimated to be living with Alzheimer's disease. Over seven million people in the US, 65 and older, live with the condition, and over 100,00 die from it annually.

South Carolina, which saw the largest measles outbreak in the United States in decades, has declared the outbreak over, state health officials announced.

The development comes as US cases reach 1,792, raising concerns about the country losing its measles elimination status achieved in 2000.

On Monday, health officials in South Carolina marked 42 days without new measles cases, confirming the outbreak that began in Spartanburg County last October has ended. There were nearly 1,000 confirmed cases over six months, including at least 21 hospitalizations.

On the upside, the outbreak led to a significant uptake in the measles, mumps, and rubella vaccinations. The state said 81,096 MMR vaccinations were given overall statewide, up 31.3 per cent from the previous year.

According to the public health experts, the increasing vaccination coverage played a significant role in helping to get the outbreak under control.

In a statement, South Carolina’s Department of Public Health’s Interim Agency Director, Edward Simmer, said that there was a 93.6 percent increase in MMR vaccinations during the outbreak.

The MMR vaccine is highly effective. One dose prevents the disease about 93 per cent of the time, and two doses raise that protection to 97 per cent.

“Vaccination – combined with other opportunities for good, solid public health work – really can be effective, even against some of the most contagious viruses,” said Dr. Brannon Traxler, deputy director and chief medical officer with the South Carolina Department of Public Health, CNN reported.

Notably, unvaccinated school-age children were the most affected by this outbreak, with 95.3 per cent of case-patients unvaccinated and 90.8 per cent of cases in children 17 years old and younger, CIDRAP news reported.

A total of 33 schools had measles exposures, and seven public school districts were affected. Over the course of six months, 874 students were asked to quarantine.

US Measles Tally Nears 1,800

As per the Centers for Disease Control and Prevention's (CDC) latest weekly update, the US saw 44 new measles cases, one more than the 43 new cases confirmed the previous week. The national total now stands at 1,792 cases.

In 2026, 22 new outbreaks have been reported, and 93 per cent of confirmed cases are outbreak-associated. While there have been no deaths in 2026 from measles, six percent of case-patients (101 of 1,792) have been hospitalized this year in the US.

South Carolina also reported an additional measles case this month. However, it was determined not to be associated with the broader outbreak, but the single case exposed more than 40 people.

Utah reported five more cases in the past week, bringing the state total to 410 for 2026. Arizona has seven more cases, raising the 2026 total to 85. The four most recent cases came from Maricopa County.

“The re-emergence of measles in the Americas is a significant setback, but one that is entirely reversible and demands decisive action,” PAHO Director Jarbas Barbosa said in a press statement.

With several countries in the Americas, including Canada, Mexico, and the US, seeing a measles resurgence, the PAHO has urged leaders to increase MMR vaccination rates.

What Is Measles?

Measles is a highly contagious virus that spreads through direct contact or through the air when an infected person coughs or sneezes. It is a vaccine-preventable disease that can cause devastating complications, including blindness, pneumonia, encephalitis, and long-term immune dysfunction.

Symptoms typically appear seven to 14 days after exposure and may include:

• high fever,
• cough,
• runny nose,
• red eyes,
• rashes across the body.

Health authorities in Kerala have sounded an alarm following five suspected cases of West Nile fever (WNF) in Ernakulam.

The cases were reported from Elanji, Eroor in Thripunithura, Pallikkara in Kizhakkambalam, Ponekkara in Edappally, and Palluruthy, The Hindu reported.

While the cases are yet to be ascertained, the southern state of India has a prevalence of mosquito-borne diseases during the summer months.

“We haven’t received any confirmation of WNF cases. These are suspected cases and can be confirmed only after tests are carried out," Dr. R. Shahirsha, District Medical Officer (DMO), Ernakulam, was quoted as saying.

Notably, the authorities have sent the samples for testing, and results will be available in 14 days.

"While no cluster has been observed, precautionary measures to prevent mosquito breeding need to be implemented,” Dr Shahirsha said. Keeping canals clean and preventing mosquito breeding inside homes and in surrounding areas are critical steps, the authorities said.

What is West Nile Fever

The disease is spread through mosquito bites, and most who get infected do not have any symptoms. However, one in every five infected people has a fever, headache, body aches, and other flu-like symptoms.

The West Nile virus also infects the nervous system and is capable of causing serious brain or spinal cord inflammation.

According to the WHO, West Nile Virus is a member of the flavivirus genus and belongs to the Japanese encephalitis antigenic complex of the family Flaviviridae.

The mosquitoes become infected when they feed on birds that carry the virus in their blood, and then bite humans and infect them.

It is found in different parts of the world, including North America, Europe, Africa, Central Asia, Australia, and Asia. Cases in 49 states in the US have been reported, and the total number of symptomatic cases in the US is 51,000 since the first cases were detected in the country in 1999.

What Are The Symptoms?

The symptoms include fever, headache, muscle aches, nausea and vomiting, diarrhoea, rash around the chest and back, swollen lymph nodes, sore throats, and pain behind the eyes.

In severe cases, individuals may have an intense headache, high fever, stiff neck, making you unable to move your chin towards your chest, confusion, muscle weakness, loss of control over your muscle movements, seizures, paralysis, and coma.

How Can It Spread?

While the mosquitoes that feed on infected birds are the carriers, there is still a lack of evidence to determine whether it comes directly from the birds. The incubation period for symptoms to show up is two to six days, but it can extend to 14 days, too.

It can be transmitted from a pregnant person to their fetus, through human milk, blood transfusion, and organ transplant. People who are over the age of 60, have cancer, diabetes, or high blood pressure are more prone to the virus.

Why Is It called West Nile Fever?

It gets its name from the West Nile district, where it was first discovered in 1937 in Uganda.

Treatment

There are no treatments or antiviral medications available for it. However, you can treat the mild symptoms at home with over-the-counter medications that you take for a cold or the flu. The best way to prevent is to protect yourself from mosquito bites.
