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?

The human brain is a complex network of billions of neurons that communicate through electrical impulses. Brain conductivity refers to the efficiency with which these electrical signals travel through brain tissue. It's akin to the speed and clarity of a digital signal through a wire. In layman terms, your brain must function in its peak condition as it is essential for various cognitive processes, including memory, attention, decision-making, and motor control.

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.

Moderna and Merck’s personalized mRNA cancer vaccine has shown statistically significant and clinically meaningful improvements. The late-stage trial showed recurrence-free survival (RFS) and distant metastasis-free survival (DMFS) when combined with Keytruda in patients with melanoma, an aggressive form of skin cancer.

The vaccine, intismeran autogene (mRNA-4157/V940), is custom-made for each patient based on the unique genetic characteristics of their tumor. It is designed to work alongside Keytruda (pembrolizumab), an immunotherapy that helps the immune system attack cancer cells.

What Makes the Vaccine Different?

According to experts, the development moves personalized cancer therapy closer to a practical clinical reality.

“A tumor-specific mRNA vaccine offers a way of making the immune response more targeted by using the individual tumor’s molecular characteristics to identify the abnormal signals that the immune system should recognize,” Prof. Jyoti Bajpai, Director – Medical Precision Immuno-Oncology, Apollo Hospitals, Mumbai, told HealthandMe.

What Did the Phase 3 Trial Find?

In the Phase 3 INTerpath-001 trial, the combination met its primary endpoint of recurrence-free survival (RFS) and a key secondary endpoint of distant metastasis-free survival (DMFS).

Compared with Keytruda alone, the combination of intismeran autogene and Keytruda showed statistically significant and clinically meaningful improvements in both RFS and DMFS.

The findings were reported in patients with stage IIB, IIC, III, or IV cutaneous melanoma who had undergone complete surgical removal of their cancer and had not previously received systemic therapy.

The mRNA Vaccine: How It Works

After tumor sequencing, up to ~34 patient-specific neoantigens are encoded into a single mRNA construct delivered in lipid nanoparticles.

Host cells translate the neoantigens, which are then presented on MHC, driving de novo and expanded neoantigen-specific CD8+ and CD4+ T-cell responses.

When combined with PD-1 blockade, the vaccine supplies the antigenic “signal” while the checkpoint inhibitor supplies the “permission” to attack.

“The result is a more focused, polyclonal, and potentially longer-lived anti-tumor immune response—exactly what is needed to clear residual microscopic disease after resection,” Dr. Shyam Aggarwal, Chairman, Medical Oncology, Sir Ganga Ram Hospital, told HealthandMe.

Early translational data from KEYNOTE-942 already showed durable neoantigen-specific T-cell responses, supporting the idea that the vaccine can generate immune memory that outlasts the treatment period.

“Immunotherapy releases the body’s natural brakes to attack cancer, whereas the custom vaccine acts like a precision GPS—training the immune system to recognize the unique genetic signature of that patient's specific tumour. Immunotherapy mobilizes the immune response, but the vaccine tells it exactly where to go,” Prof. Jyoti said.

What Could It Mean for Cancer Treatment?

“The practical implication is a shift in the adjuvant paradigm: rather than relying solely on broad immune checkpoint inhibition or chemotherapy, we can now envision adding a tumor-specific ‘instruction set’ that educates the patient’s own T-cell repertoire against the unique mutational fingerprint of their cancer,” the noted oncologist said.

He added that the manufacturing turnaround, currently ~6 weeks from biopsy to first dose, remains a logistical and cost challenge. However, the COVID-era mRNA infrastructure has shown that rapid, decentralized production of custom constructs is feasible.

mRNA’s Potential For India

India’s cancer burden has continued to rise steadily over the past five years, with the estimated number of new cancer cases increasing from 14.26 lakh in 2021 to 15.70 lakh in 2025, while annual cancer-related deaths also climbed from 7.89 lakh to an estimated 8.69 lakh during the same period, according to data placed before Parliament recently.

For India, this technology has intriguing potential, Dr Jyoti said.

While typical skin melanoma is less common here, India sees higher rates of acral and mucosal subtypes, which tend to be aggressive and diagnosed late.

“A tailored neoantigen approach could be very useful for these complex cases. However, manufacturing costs, long turnaround times for genomic sequencing, and cold-chain logistics mean translating this into routine clinical care in India may take time,” she added.

US CDC Says COVID ‘Growing’ In Nearly Every State: What You Should Know

Updated Aug 21, 2026 | 09:09 PM IST

SummaryEven though the numbers aren’t especially high and there aren’t many hospitalizations or deaths reported, COVID-19 can still be serious and even deadly, especially for people who remain vulnerable to severe disease.

Almost all states in the US are reporting a growing summer wave of COVID-19 cases, according to a report by the Centers for Disease Control and Prevention (CDC).

While the numbers aren’t especially high and there aren’t many hospitalizations or deaths, the test positivity rate for the week ending August 8 rose above 3% for the first time since March, with numbers climbing in every state. Emergency department visits related to COVID-19 are also “very low.”

Wastewater Data Offers Closer Look At COVID Activity

According to the CDC, wastewater data can be a key tool for tracking where the virus may be circulating. Testing sewage can detect the presence of COVID-19 in a community and “can pick up signs of infection even from people who feel perfectly healthy,” the CDC said.

COVID-19 Activity By State

  • Hawaii and Mississippi show signs of elevated viral activity.
  • Both states have “moderate” levels of COVID-19.
  • Wastewater data for Mississippi is limited.
  • The West and South are seeing higher COVID-19 activity than other regions.
  • Low wastewater levels: Alabama, Alaska, California, Florida, Georgia, Nevada, Oregon, Texas and Washington.
  • Very low levels: The remaining states.
  • In Alabama, COVID-19 is not reflected in hospitalizations or mortality data yet, but cases are registering an “uptick” rather than a surge.

“It is going up. We don’t know how to describe these numbers that we’re seeing in terms of what the denominator is anymore,” Dr. Scott Harris, state health officer for the Alabama Department of Public Health, told the media.

“Now we just know when we get a positive test, and we don’t even have clinical data sometimes to put that in context.”

‘August Is Solidly Covid Season’

“August is solidly Covid season,” Dr. Caitlin Rivers, an expert in outbreak science and senior scholar at the Johns Hopkins Center for Health and Security, told CNN.

“Right now, the South and the West are sort of the leading edge of this Covid season. In the past, it almost always starts in Florida, Texas and Georgia, which is exactly what we’re seeing this year.”

Who Is At Higher Risk?

COVID-19 can still be serious and even deadly, especially for people who remain vulnerable to severe disease. These include:

  • Elderly individuals
  • Pregnant women
  • People with chronic heart disease
  • Patients with COPD or interstitial lung disease (ILD)
  • Those with chronic kidney or liver disease
  • Immunocompromised individuals

How To Prevent COVID-19?

To reduce the risk of infection, people should:

  • Stay up to date with COVID-19 vaccinations.
  • Wear masks in crowded indoor settings.
  • Maintain hand hygiene.
  • Ensure good ventilation.
  • Avoid close contact with others when unwell.

Anyone experiencing symptoms such as fever, cough or breathlessness should get tested and seek timely medical advice.

If you didn’t get a COVID-19 vaccine last year, you may want to talk to your healthcare provider or pharmacist about getting one, including the vaccine formulated for last season, Dr. James McDonald, commissioner of health for the New York State Department of Health, told CNN.

In a world first, a 15-foot reticulated python named Jodie Foster has successfully undergone electrochemotherapy, a pioneering cancer treatment usually used in humans.

The reticulated python is a species native to South and Southeast Asia. It is the world’s longest snake and the third heaviest.

The 50kg python, named Jodie Foster after the Hollywood star, underwent the treatment after being diagnosed with fibrosarcoma, a malignant tumor, in her jaw. The tumor was initially removed through surgery but later returned and began invading her jawbone.

“Months later, 50kg Jodie Foster is cancer-free and back to her usual ‘bright and feisty’ self,” Chester Zoo in the UK said in a statement.

What Happened To Jodie Foster?

Keepers became concerned when Jodie started eating less and became more inactive. Tests confirmed a fibrosarcoma in her jaw. Vets initially removed the tumor through surgery.

Tests confirmed she had a fibrosarcoma, a malignant tumor, in her jaw. Although vets initially removed the tumor, it later returned and started destroying part of her jawbone. Doctors feared further surgery alone would not be enough and that the tumor could eventually make it difficult for her to eat.

“We were facing the possibility of losing her as the tumor made it more and more difficult for her to eat, so we worked with cancer specialists to see whether we could adapt electrochemotherapy for a snake," said Ian Ashpole, Veterinary Officer at Chester Zoo :

“As far as we're aware, this is the first time it's ever been used in one," Ashpole added.

How Was The Human Cancer Treatment Adapted For A Snake?

With no operating table large enough for a python of Jodie's size, the veterinary team had to improvise.

For the operation that lasted 90 minutes, Jodie was first anaesthetized in her habitat before being taken to the veterinary center.

Two operating tables were placed together to create a surface roughly the size of a double bed. Heated blankets and warm air were also used to keep her body temperature stable.

Dr. Ashpole first removed the tumor and performed a hemi-mandibulectomy, removing part of the diseased jawbone. Electrochemotherapy was then used to target any remaining cancer cells.

What Is Electrochemotherapy? How Does It Work?

According to Cancer Research UK, electrochemotherapy combines chemotherapy with small electrical pulses.

It is used to treat some cancers that begin in the skin or have spread to the skin. However, its use in Jodie Foster marks a world first in veterinary medicine for a snake.

“Electrochemotherapy is an emerging treatment, and this was the first time it had been used in a snake,” said Jose Alvares Picornell, Department of Small Animal Clinical Science, University of Liverpool, who was part of the three-hour-long surgery.

The treatment combines the cancer drug bleomycin with carefully controlled electrical pulses delivered directly to the tumor site.

  • The electrical pulses temporarily make cancer cells more permeable.
  • This allows the drug to enter the cells more effectively.
  • The approach can allow lower doses of chemotherapy to be used.
  • It can sometimes be delivered in a single procedure.

Jodie Foster Back 'Bright And Feisty'

Despite losing part of her jawbone, Jodie's appetite and hunting ability have not been affected, the Zoo officials said, adding that she continues to strike, grip and swallow food without difficulty.

Months of observation have shown no problems with feeding, and a final check confirmed that she remains free of signs of the cancer returning. The officials added that Jodie is eating normally, exploring her habitat and behaving as usual.

“Seeing her back to her normal bright and feisty self has been incredibly rewarding. A few months ago, we genuinely didn't know whether she'd survive," Dr Ashpole added.
