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.

Since July 2025, at least 52 maternity units across the United States have been shut down. Eight more closures were announced recently, raising concerns that upcoming federal Medicaid cuts could further restrict access to pregnancy and neonatal care, especially in rural communities and regions with limited healthcare resources.

The closures come as hospitals prepare for changes under the HR1 bill, which will reduce federal Medicaid funding and introduce stricter eligibility rules and work requirements. Although the legislation's impact is expected to be felt in 2027, some hospitals have already cited the anticipated changes as a reason for ending maternity services.

Maternity wards are expensive to operate because they require round-the-clock staff, special equipment and teams trained for emergencies. Low reimbursement rates, staffing shortages, and declining birth rates have already placed financial pressure on hospitals. Reduced Medicaid funding could make it harder for some hospitals to keep these services.

Erin Jones, senior director of legislative and strategic counsel at the nonprofit March of Dimes, warned that the changes could worsen existing healthcare problems.

“We’re deeply concerned that these changes already have and will continue to worsen an already serious maternity care crisis,” she said. “Reduced funding and restrictions on how states finance Medicaid will put additional pressure on state budgets and hospitals, increasing the risk that communities lose essential maternity services and specialized providers close to home.”

Hospitals that have permanently closed maternity wards include Centra Southside Community Hospital in Virginia and St Mary’s Sacred Heart Hospital in rural northeastern Georgia. Both mentioned upcoming federal Medicaid policy changes as the reasons for their decisions.

Medicaid is a major source of health coverage for low-income Americans, paying for approximately 40% of births in the country. Changes to the program could affect hospitals’ finances as well as patients’ ability to receive health coverage.

Although pregnant women are supposed to be exempt from the new work requirements, eligibility rules could still create difficulties for some patients.

Benjamin Sommers, a professor of healthcare economics at Harvard University’s T.H. Chan School of Public Health, said the law would “absolutely” affect pregnant women and pregnancy care facilities.

“It’s not true that this law in any way protects Medicaid for pregnant mothers, for low-income parents. It adds financial strain to the providers and the insurance program that they rely on,” he said.

Sommers warned that some pregnant women are enrolled through Medicaid expansion rather than a pregnancy-specific category. If state authorities do not know that a beneficiary is pregnant, she may not be automatically protected from the new requirements.

“Someone could be enrolled through Medicaid expansion, they could get pregnant and they could mistakenly think – because they heard it on the news that this law doesn’t affect pregnant people – [they’re] fine, and it turns out the state doesn’t know they’re pregnant and they lose coverage."

Rural Communities At Risk

The consequences of maternity unit closures can impact other aspects other than childbirth. Pregnant women may have to travel farther for antenatal appointments, emergency obstetric care and delivery, adding transport costs and making timely treatment more difficult.

March of Dimes has identified 31 rural hospitals with labour and delivery services that could be at risk. If these units close, 96 counties could lose their remaining local delivery services, Jones warned. “Losing these services means fewer places to deliver safely and fewer options for pregnancies requiring specialized care,” she added.

The organisation’s 2026 report found that 34.6% of US counties were maternity care deserts, meaning they had no obstetric clinicians or birthing facilities. These areas are home to approximately 2.4 million women of reproductive age.

Tech entrepreneur Bryan Johnson is expanding his horizons in longevity health experiments to female physiology, including monitoring his girlfriend Kate Tolo’s nighttime clitoral engorgement.

The purpose is to understand how genital blood flow may give clues about female sexual function and cardiovascular health.

The experiment is part of his extensive effort to collate data on women’s health that could be channeled into useful biomarkers.

But while research suggests a connection between genital blood flow, sexual arousal and cardiometabolic health, tracking these changes during sleep may not be an established way to screen heart disease.

Bryan Johnson Is Tracking His Girlfriend's Clitoral Blood Flow

Bryan Johnson and Kate Tolo are in the process of creating a detailed health-monitoring program through their company, Immortals. Their aim is to improve in-depth understanding of female physiology.

The process is partly inspired by research on erectile dysfunction in men. As erections depend on healthy blood vessels, erectile dysfunction can sometimes help in the detection of cardiovascular disease.

In an interview discussing the project, Tolo explained the reasoning behind investigating genital blood flow in women. “Because the penis has smaller blood vessels than the rest of the body, and so it's the first thing to show up when problems happen. So it's all about blood flow. That's why it should work for women just as well as it works for men, because we have blood vessels too,” she said. Johnson also highlighted nighttime erections as a physiological measure worth studying.

However, the evidence linking male erectile dysfunction with cardiovascular risk is more established than the evidence for using female genital blood flow measurements as a cardiovascular monitoring tool.

What Does Clitoral Engorgement Reveal About Sexual Health?

The clitoris contains erectile tissue supplied by blood vessels. During sexual arousal, increased blood flow contributes to genital engorgement and physiological changes associated with sexual response.

Blood circulation is therefore one component of sexual function. Reduced genital blood flow or increased vascular resistance may be associated with difficulties involving arousal, lubrication or orgasm.

A small pilot study published in the International Journal of Impotence Research examined 27 women and found that clitoral tissue perfusion was linked with scores measuring sexual function, including arousal, lubrication, orgasm and satisfaction.

The findings indicate that genital blood supply may be relevant to understanding female sexual health. However, the study was small and did not establish that nighttime clitoral blood-flow monitoring can diagnose sexual dysfunction.

Sexual function is also influenced by hormones, medications, neurological health, psychological factors, relationships and underlying medical conditions. Blood flow alone cannot explain every aspect of sexual wellbeing.

Can Clitoral Blood Flow Reveal Cardiovascular Risk?

The endothelium, the inner lining of blood vessels, helps regulate circulation. Metabolic conditions like diabetes, insulin resistance, high cholesterol, and hypertension can affect vascular function, including genital tissues.

A 2024 review published in the European Journal of Preventive Cardiology, which included 54 studies and nearly 149,000 participants, also found that women with cardiovascular disease had a higher risk of female sexual dysfunction.

This supports a relationship between cardiovascular and sexual health, but it does not validate Johnson’s tracking method.

Nocturnal genital responses may provide useful information about physiology, but researchers would need to establish what constitutes a normal pattern, how measurements vary with sleep and hormonal cycles, and whether particular changes reliably predict disease. The approach would also need to be tested in larger populations.

Pope Leo XIV has announced that he will undergo surgery in the coming days to have a nodule removed that was discovered in his lung recently. The 71-year-old pontiff said it was detected early and was well contained, which is why the doctors recommended a removal procedure.

The Vatican has not disclosed whether the nodule is benign or cancerous. The procedure has nevertheless sparked attention to lung nodules, a common medical finding that can sometimes warrant further clinical investigation to rule out cancer and other serious diseases.

“Recently, during some medical examinations, doctors found a localized nodule in my lung,” the pope said during his Sunday address in St. Peter’s Square on October 11. “It was detected at a very early stage and is well contained.”

He added, “The doctors believe it is advisable to intervene, so, following their advice, I have decided to undergo surgery to remove it. The operation is already scheduled for the next few days.” The Vatican said the pope’s recovery may take about a week.

Dr. Vinayak Maka, Senior Oncologist, Department of Oncology, Ramaiah Memorial Hospital told HealthandMe, "A lung nodule is a small, round or oval-shaped growth in the lung, typically less than 3 cm in size, most often discovered incidentally during a chest X-ray or CT scan done for an unrelated reason."

According to the American Thoracic Society, lung nodules may develop because of scar tissue, a previous lung infection or irritation. In a few cases, however, a nodule may be an early sign of lung cancer. Most lung nodules are benign.

"A lung nodule finding on a CT scan often triggers panic, but the reality is reassuring. Over 95% of lung nodules are benign, arising from old infections, scars, or inflammation. Still, understanding when a nodule warrants concern can be lifesaving." Dr. Vinayak Maka added.

Doctors assess the nodule's size, shape, location, and appearance on imaging, along with the patient’s medical history and other risk factors.

Not every lung nodule requires surgery. Many are monitored through repeat CT scans to determine whether they remain stable or grow over time. Doctors may recommend additional testing or removal when:

• The nodule grows: An increase in size on follow-up scans can raise suspicion of cancer and prompt further investigation. Doctors say nodules smaller than 6 mm have a very low cancer risk (under 1%) and usually only need routine follow-up. Those measuring 6–8 mm carry a slightly higher risk (1–2.5%) and are typically monitored with a repeat CT scan after 6–12 months.

• Its appearance is concerning: Certain shapes, edges or other imaging features may make a nodule more suspicious.

• Risk factors: Older age, history of smoking, family history of lung cancer, and past exposure to substances like asbestos may be considered.

• Imaging is inconclusive: When the possibility of cancer remains significant, obtaining tissue for examination may be necessary.

• The nodule is considered sufficiently suspicious for cancer: If the risk is high, doctors may recommend surgical removal rather than relying on monitoring or a less invasive biopsy.

The decision also depends on the nodule’s location, whether it can be reached safely for a biopsy and the patient’s overall health. Surgery may provide both a confirmed diagnosis and treatment if the growth proves to be an early-stage cancer.

Stephen Liu, a lung cancer specialist at Georgetown University in Washington and division chief of haematology-oncology at MedStar Georgetown University Hospital, explained the role of surgery in such cases.

“When there is sufficient concern, and when it is safe to do so, based on the location of the nodule and the overall health of the patient, surgical removal can provide a definitive diagnosis,” he said.

Pope Leo said his lung nodule was detected at a very early stage. His planned surgery is therefore a decision made by his treating doctors based on information that has not been made public.

Italian Prime Minister Giorgia Meloni expressed support for the pontiff, saying, “I would like to express to the Holy Father my personal support, and that of the Italian government, as he faces this challenge in the coming days.”

She added, “The serenity and composure with which he spoke about it during today’s Angelus are reassuring."
