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.

Amid the scare of hantavirus infection, US health officials informed that they are investigating a potential case in an Illinois resident.

The Illinois Department of Public Health (IDPH) noted that the incident is not linked to the MV Hondius cruise ship outbreak.

MV Hondius had 18 American nationals, and all have been medically evacuated back to the US. While 16 people are in Nebraska at the nation's only national quarantine unit, two people are being monitored in Atlanta.

In a statement, the IDPH said that the person “lives in Winnebago County, has not travelled internationally, and has not come in contact with individuals associated with the MV Hondius outbreak”.

Officials suspect that the possible hantavirus infection in the Illinois person to be a case of the North American strain of the virus while cleaning a home where rodent droppings were present.

“Unlike the Andes strain of Hantavirus responsible for the cruise outbreak, the North American strains are not known to spread from person to person. The risk of contracting Hantavirus of any kind remains very low for Illinois residents,” the officials said.

However, they added that the CDC is conducting additional testing to confirm that the resident is positive for Hantavirus. CDC staff told IDPH its confirmatory test result could take up to 10 days to complete.

Hantavirus Cases In The US

Excluding this latest potential case, Illinois has had 7 positive cases of Hantavirus since 1993, most recently in March 2025.

Since surveillance began in 1993, the US has recorded 890 cases of Hantavirus over 30 years (1993-2023)

The Hantavirus strain most commonly seen in the US is caused by exposure to rodent droppings and is NOT contagious from person to person.

The rodent species (long-tailed pygmy rice rat) known to carry the Andes strain of the virus in South America does not live in the U.S.

First Case Of Hantavirus Diagnosed In Israel

Earlier, a case of hantavirus was also reported from Israel, that was not linked to the MV Hondius ship.

The case in Israel, reported by the local newspaper Maariv, is believed to have been infected during a stay in Eastern Europe several months ago. It is reportedly not linked to the ongoing outbreak linked to the MV Hondius cruise ship in the Atlantic Ocean.

The patient underwent an antibody test after the symptoms appeared, which showed exposure to hantavirus, the report said. A PCR (polymerase chain reaction) test was then conducted to detect the virus’s genetic material, confirming the infection, the report said.

The patient was said to be in stable condition, not in need of intensive care or strict isolation, and was being kept under medical observation.

Details about the patient and the medical center where the diagnosis was made could not yet be published, but have been reported to the country's Health Ministry.

Hantavirus is primarily transmitted through contact with infected rodents or exposure to their urine, droppings, and saliva, though rare cases of person-to-person transmission have also been reported.

According to the World Health Organization (WHO), 11 cases — including three deaths — have been confirmed so far. However, additional suspected and confirmed cases are continuing to emerge across countries.

“At the moment, there is no sign that we are seeing the start of a larger outbreak,” said Tedros Adhanom Ghebreyesus, WHO Chief, in the latest media briefing.

However, he said that the situation could still change.

“Given the long incubation period of the virus, we might see more cases in the coming weeks,” he said.

Polycystic Ovary Syndrome (PCOS), a condition affecting more than 170 million women worldwide, has now been officially renamed Polyendocrine Metabolic Ovarian Syndrome (PMOS), according to a global study published today in The Lancet.

The new name reflects a major shift in understanding the condition — from being viewed primarily as a gynecological disorder to being recognized as a complex, multisystem condition affecting several aspects of health.

The new term PMOS acknowledges that the condition involves:

• Endocrine health
• Metabolic health
• Reproductive health
• Dermatological health
• Psychological health

“For too long, the narrow definition of PCOS has overlooked its metabolic and hormonal complexity, leaving many patients undiagnosed or misunderstood,” Cree added.

Why Was PCOS Renamed To PMOS?

Calls to rename PCOS date back to the 1990s and early 2000s. In 2012, the U.S. National Institutes of Health (NIH) recommended a name change after experts concluded that the term PCOS was misleading and confusing for both patients and healthcare providers.

“The name focuses on a criterion — polycystic ovarian morphology — which is neither necessary nor sufficient to diagnose the syndrome,” NIH experts wrote in the report.

Although PCOS has long been understood as a metabolic condition, experts said the name inaccurately narrowed its scope and overemphasized ovarian cysts and fertility issues.

This often led to:

• Delayed diagnoses
• Fragmented care
• Stigma
• Missed opportunities for early intervention

How Was The Name Change Decided?

The renaming process involved consultations with thousands of patients and healthcare professionals across the world.

The effort was supported by 56 academic, clinical, and patient organizations.

Experts said the transition from PCOS to PMOS will occur over the next three years through a phased global implementation strategy.

What Does PMOS Mean?

The new name aims to explain the condition more accurately and comprehensively.

Polyendocrine means it affects multiple hormones in the body.

Metabolic refers to issues linked to weight, insulin, blood sugar, and heart health.

Ovarian highlights its impact on ovulation and reproductive health.

Syndrome refers to a group of symptoms occurring together.

In simple terms, PMOS is a hormonal and metabolic condition that can affect periods, fertility, skin, mood, weight, and long-term health.

Experts said the new terminology intends to:

• Reflect the condition’s hormonal complexity
• Acknowledge its strong metabolic and cardiometabolic effects
• Continue emphasizing ovarian involvement without over-focusing on fertility

According to the study, PMOS could also:

• Promote earlier and more accurate diagnosis
• Support more holistic, patient-centered care
• Reduce stigma associated with fertility-focused terminology
• Expand research into metabolic and systemic impacts

Hantavirus cases have climbed to 11, including three deaths, WHO Director-General Tedros Adhanom Ghebreyesus said today.

During a media briefing on hantavirus, Tedros stated that all eleven cases are among passengers or crew members onboard the MV Hondius.

“Nine of the eleven have been confirmed as Andes virus, and the other two are probable,” he added.

All suspected and confirmed cases have been isolated and managed under strict medical supervision, minimizing any risk of further transmission.

Tedros said individual countries were now responsible for their citizens after the evacuation, adding: “I hope they will take care of the patients and the passengers, helping them and also protecting their citizens as well. That’s what we expect.”

Will Hantavirus Become A Public Health Threat?

Noting that “at the moment, there is no sign that we are seeing the start of a larger outbreak,” Tedros said the situation could still change.

“Given the long incubation period of the virus, it’s possible we might see more cases in the coming weeks,” he said.

Acclaimed vaccine scientist Prof. Peter Hotez from the Texas Medical Center (TMC) also said more cases could emerge, but ruled out the risk of a major epidemic.

“We might see additional cases, but I don't think this will be a major epidemic beyond the obvious human tragedy of those who lost their lives, and possibly a few others who could still get very sick,” he said in a post on social media platform X.

“New World hantavirus infections are rough stuff. Once symptoms begin, the resulting cytokine storm and ARDS means there's not much of a window before getting patients into an ICU, and often on ECMO (extracorporeal membrane oxygenation), which requires a high level of skill,” Prof. Peter said.

He also linked increasing zoonotic spillovers and rising arthropod-borne illnesses to “climate change pushing animal reservoirs to explore new habitats, together with deforestation and urbanization.”

“It's animals and vectors closer to humans and people coming closer to animals and vectors,” he added.

“I don't think this particular hantavirus outbreak will accelerate much beyond where it is now, but that's not the point.”

Dutch Hospital Quarantines 12 Healthcare Workers

Meanwhile, Radboud University Medical Center (Radboudumc) in the Netherlands has placed 12 employees in quarantine for six weeks as a precaution after incorrect procedures were followed while caring for a hantavirus-infected patient from the Dutch cruise ship.

The hospital said on Monday that the issue involved procedures for drawing and processing blood samples, as well as the disposal of the patient's urine, according to Xinhua news agency.

“This blood was processed according to standard procedure. Due to the nature of the virus, this blood should have been processed according to a stricter procedure,” Radboudumc said in a statement, without specifying what the stricter measures should have entailed.
