At just 14 years old, Siddharth Nandyala is already changing the face of modern medicine. A native of Anantapur in Andhra Pradesh in India, living in Frisco, Texas, this young genius is causing global waves with the development of CircadiaV, a revolutionary AI-powered mobile app that can diagnose heart disease within a record seven seconds. With nothing more than a smartphone and sophisticated machine learning, Siddharth's invention has the potential to transform cardiovascular disease screening—one of the globe's top causes of death.

With certification from international tech giants such as Oracle and ARM, Siddharth is officially the world's youngest AI-certified professional but behind the titles and accolades, it's his vision for affordable, early healthcare interventions that really sets him apart. While most teenagers are at the age playing around with social media and video games, Siddharth is addressing medical challenges on a global scale.

Heart disease remains the primary cause of death in the world, resulting in more than 17.9 million deaths annually, as reported by the World Health Organization (WHO). A significant portion of those deaths are avoidable if diagnosed early enough. Unfortunately, the absence of medical diagnostic infrastructure in remote and underprivileged regions—particularly in developing nations—is an enormous challenge.

How CircadiaV Works?

What sets CircadiaV apart is its non-invasive, fast, and precise method for early detection of heart disease. The app can capture heart sounds by holding a smartphone against a patient's chest. It removes ambient noise, analyzes the audio data through a cloud-based machine learning model, and provides results in seven seconds.

The program can identify various cardiac anomalies, such as:

• Arrhythmias (irregular heartbeats)
• Early indications of heart failure
• Indicators of coronary artery disease
• Abnormalities in the heart valves

And it's amazingly precise—with a detection accuracy of more than 96%, as confirmed through testing on over 15,000 patients in America and another 700 in India, including at the Guntur Government General Hospital (GGH).

This application does not substitute for the EKG but is used as a quick, scalable pre-screen," Siddharth said to the Smithsonian Magazine. That clarification is important—it is not intended for consumer use at home or consumer diagnostics, but is designed to assist medical personnel, especially in impoverished environments where full cardiac diagnostics might not be within reach.

That is where CircadiaV comes in. Its low-cost, cloud-based, and portable nature makes it a perfect device for community clinics and frontline health workers. The application can be utilized in rural areas to give an early diagnosis, leading to early referrals and possibly cutting long-term morbidity and mortality.

An initial potential diagnosis in patients otherwise unlikely to have had access to medical treatment may in the end save long-term morbidity and mortality from this disease.

That is, this app could literally be a lifesaver—particularly for patients in rural towns, refugee camps, or even wartime zones where cardiologists and expensive diagnostic technology are scarce.

More Than Just a One-Time Invention

Siddharth's foray into innovation had not begun with CircadiaV. Prior to this, he had created a low-cost prosthetic arm, a innovation to enhance mobility for individuals with limb loss in underprivileged communities. He also had started STEM IT, a company that creates science and technology kits for children, enabling experiential STEM learning across socioeconomic barriers.

His success has already seen him receive national and international acclaim, including a Certificate of Recognition from the US House of Representatives and a congratulatory letter from President Joe Biden.

And although he is as old as some of his classmates are young, Siddharth has just become a computer science major at the University of Texas. And his goals don't end there. He hopes to make CircadiaV capable of not just detecting lung diseases like pneumonia and pulmonary embolism, but also of analyzing recordings of lung sounds just like the app presently analyzes heart sound recordings.

Clinically, prompt detection is the key to success with cardiovascular treatment. Most terminal cardiac illnesses—such as congestive heart failure or severe coronary artery disease—are salvageable if detected early. But when symptoms intensify, choices narrow, and survival rates plummet.

By providing healthcare professionals with an advantage with CircadiaV, Siddharth is delivering:

• Earlier detection = quicker decision-making on treatment
• Non-invasive screening guarantees greater uptake in community-based screening
• Cloud-fueled insights enable real-time collaboration among rural clinics and urban hospitals

Consider the following: a community health worker in a remote village in India uses a smartphone to identify early-stage heart failure in a 55-year-old man. Rather than waiting weeks for a cardiology visit, that patient can be expedited for further testing and treatment—saving his life.

The app is particularly useful for terminal heart patients whose survival chances raise significantly if the condition is detected at the asymptomatic or initial phases. With correct warnings regarding the development of arrhythmias or valve malfunctions, the technology enables physicians to act before it is too late.

Children’s TV presenter Johnny Ball spoke openly on Monday’s Good Morning Britain about his prostate cancer diagnosis from 2022. During the ITV show, hosts Ed Balls and Susanna Reid discussed Ball’s health and recovery. The 87-year-old, father of radio host Zoe Ball and well-known for shows like Play School, revealed that he successfully completed treatment and is now in good health.

Reflecting on his experience, Ball said, “I was diagnosed with prostate cancer in August 2022. Thankfully, after three months of daily radiation therapy starting in September, I’m through it and feeling well.” He acknowledged that the disease can be fatal, citing friends who lost their lives to it, including Goon Show star Harry Secombe and comedian Bob Monkhouse. “I’m 20 years younger than them, and I feel fortunate because today we can treat it successfully,” he added.

Ball also stressed the importance of regular check-ups. Despite showing no symptoms, his cancer was discovered during a routine GP visit. His PSA levels were at 30, far above the normal threshold of three, highlighting the value of screening even in the absence of symptoms.

What Is Prostate Cancer?Prostate cancer develops in the prostate, a small gland in the male reproductive system responsible for producing fluid that forms part of semen. The condition occurs when cells in the prostate grow uncontrollably, potentially forming a tumor. While some forms grow slowly and may not immediately threaten health, the cancer can be dangerous if it spreads beyond the prostate. Factors that increase risk include age, genetics, and ethnicity.

What is the Prostate?

The prostate is a small gland located just below the bladder in men. Its primary role is to produce seminal fluid, which helps nourish and transport sperm.

How Does Prostate Cancer Develop?

Cancer in the prostate begins when certain cells start growing abnormally. These cells multiply faster than normal, eventually forming a tumor.

Early Warning Signs Of Prostate Cancer

Prostate cancer often does not cause noticeable symptoms in its early stages. When symptoms do appear, they usually involve changes in urination:

• Frequent urination, especially at night
• Difficulty starting or stopping urine flow
• Weak or interrupted stream
• Urgency, or a sudden, hard-to-control need to urinate
• Feeling of incomplete emptying after urination

Other possible signs include:

• Blood in urine or semen
• Erectile dysfunction
• Pain or burning during urination or ejaculation
• Persistent pain in the lower back, hips, pelvis, or upper thighs
• Weakness or numbness in later stages

Because early prostate cancer often produces few or no obvious symptoms, regular check-ups and screenings are crucial, particularly for men with risk factors. Anyone noticing these signs should seek medical advice promptly.

Massachusetts health officials have reported two new human cases of West Nile virus, raising the state’s total this season to eight. In its update on Friday, September 6, 2025, the Department of Public Health (MDPH) said the latest cases involve a woman in her 60s from Middlesex County and a man in his 50s from Suffolk County.

Because of these new infections, the risk level for West Nile has been raised to “high” in four communities, Arlington, Chelsea, Medford, and Waltham. Overall, 47 municipalities and more than 200 cities and towns across Massachusetts are now considered high-risk.

Public Health Commissioner Robbie Goldstein noted that the state is “almost out of the peak season” for West Nile transmission, but added that the threat will remain until the first hard frost arrives. He advised residents to continue protecting themselves by using mosquito repellent and wearing long sleeves and pants to reduce exposed skin.

In rare but serious cases, the virus can affect the nervous system, leading to brain or spinal cord inflammation (encephalitis or meningitis). These severe infections may cause symptoms such as confusion, seizures, paralysis, or even coma.

How Common Is West Nile Virus?

This year alone, the Centers for Disease Control and Prevention (CDC) has confirmed 1,137 cases of West Nile across 42 states as of September 23, 2025. Of those, 742 were classified as “neuroinvasive,” meaning the infection spread to the nervous system.

West Nile Virus Symptoms and Causes

• Fever
• Headache
• Muscle aches
• Nausea or vomiting
• Diarrhea
• Rash on the chest or back
• Swollen lymph nodes
• Sore throat
• Pain behind the eyes

Severe symptoms of West Nile encephalitis or meningitis can include:

• Sudden, intense headache
• High fever (above 103°F or 39.5°C)
• Stiff neck
• Confusion or disorientation
• Muscle weakness
• Tremors or convulsions
• Seizures
• Paralysis
