It's a frequent misconception that identical twins share fingerprints. Each twin has a unique set of fingerprints that convey a different tale, despite the fact that they may appear remarkably alike and share a lot of DNA.

Are you wondering how identical twins might differ so much from one another in such a small way?

Let's look at the intriguing science that underlies it.

Twin Types: Not All Twins Are Created Equal

To understand why fingerprints differ, we must first look at the two main types of twins—identical and fraternal—and how they form.

Twins That Don’t Look Alike, or Non-Identical Twins

Fraternal twins are produced when two different sperm fertilize two different eggs. Since they share about half of their DNA, they are genetically identical to any other sibling. But, what are fraternal twins? They are also known as dizygotic twins. They come from two separate eggs, fertilized by two different sperm. They also share about 50% of their genetic material, and have unique physical traits, often different sexes at birth too.

Because of this genetic variability, fraternal twins, like non-twin siblings, can have different sexes or distinct hair and eye colors.

Twins That Are Identical

Identical twins, on the other hand, develop from a single fertilized egg that divides into two embryos. Their DNA is almost the same, but not exactly the same, thanks to this process. Also known as the monozygotic twins come from a single fertilized eggs that splits into two embryos. These twin share the same genetic material, which is what leads to their identical physical traits and the same sex at birth. However, there are slight differences that can emerge due to environmental factors during pregnancy, including the space in the womb.

According to a 2021 study referenced by Smithsonian Magazine, only 38 pairs of identical twins and two sets of triplets had completely identical genes. Because of their tight genetic ties, they have remarkable physical similarities, such as similar skin tones, eye colors, and hair colors. However, minor distinctions like height, weight, and fingerprints distinguish them.

Fingerprints: Not Just Genetic Information

Although fingerprint patterns are influenced by heredity, environmental variables within the womb provide a twist.

Experts in forensic science say there is almost little likelihood that identical twins' fingerprints will match. Although they may have similar overall characteristics, such ridges and loops, the specifics are different.

The following factors affect fingerprints:

• Access to nutrition during pregnancy
• The length of the umbilical cord influences blood flow.
• Growth rates of fingers
• Placement inside the womb
• Both DNA and these environmental influences shape fingerprints, which are fixed for life by the 13th to 19th week of foetal development.

Solving the Fingerprint Mysteries

According to some research, twins' fingerprints could seem similar at first glance, but a deeper look reveals variations in the pattern branches and ridge spacing.

According to the National Forensic Science Technology Centre, no two individuals—not even identical twins—have ever been found to have the same fingerprints.

It adds even more individuality because even your own fingers have different prints!

Vapes were marketed as a safer option than cigarettes, but research now shows they carry serious health risks -- from lung damage to meningitis to cancer.

Vaping has been a serious concern in the United States, with New York Attorney General Letitia James in 2025 filing a lawsuit against e-cigarette manufacturers and distributors.

The lawsuit accused the companies of fueling a youth vaping crisis, alleging that these companies that manufacture vapes, especially with flavors, have misled consumers about the safety of their products while deliberately targeting young people through deceptive marketing.

Now, a new study, published in JAMA Network Open, has for the first time assessed trends in young children's nicotine exposures across all types of products.

Shockingly, electronic cigarette-related incidents increased 243 percent over the past eight years in young children, especially among those under five years of age, said researchers from the Rutgers New Jersey Medical School.

In contrast, tobacco exposures from conventional products such as cigarettes decreased by 43 percent.

Unlike cigarettes, these devices are often ready to use, brightly colored, require little effort to activate, and appear more like toys than a harmful product.

"This significant spike in children breathing in these substances tells us the risk has changed: It's no longer just about a toddler swallowing something they found on the floor," said lead author Perry Rosen, who conducted the research at the New Jersey Poison Control Center.

"Many recent cases involve children actively using e-cigarette devices after gaining access to them," Rosen added.

Key Findings

The findings were based on an analysis of more than 92,000 reported nicotine exposures in children ages 5 and younger between 2016 and 2023.

The researchers noted that vaping risks often involved children who inhaled the vapors directly from the devices. They also found that children exposed to e-cigarettes were more likely to require a visit to a health care facility compared with those exposed to cigarettes.

According to researchers, young children naturally mimic the behaviors they see around them. So, parents and caregivers must keep vaping devices away from the reach of young children.

Previous research has shown that even moderate ongoing nicotine exposure can lead to lasting health effects on developing lungs, including increased risk of bronchitis and worsening asthma.

"When children see caregivers or older family members vaping, they may copy that behavior—bringing the device to their mouth and inhaling—without any understanding they are exposing themselves to a harmful substance," said Diane Calello, executive and medical director of the New Jersey Poison Control Center.

Vaping: A Concern

Vaping has become a more common form of tobacco use among American middle and high school students.

As per the US Centers for Disease Control and Prevention (CDC), nearly 1.6 million students used e-cigarettes in 2024, with 87.6 percent of them opting for a flavored product.

It is the flavor that makes it even more addictive, and people want to keep smoking it, resulting in it being emptied and refilled way more quickly.

This means those who smoke flavored cigarettes consume more tobacco than those who smoke unflavored ones.

Conceiving after 7 years of marriage—riddled with societal shame and self-doubt and a host of tests—was a moment of immense joy to Shalini, a 30-year-old IT professional.

Shalini was cared for, pampered, and showered with gifts. But the happiness was short-lived. At 10 weeks, her doctor delivered devastating news: there was no fetal heartbeat, and the pregnancy would have to be terminated.

Shalini couldn’t process; years of taunts of not being able to deliver a child came back to her ears—a voice so profound that she was unwilling to abort, let come what may.

However, in a week, the miscarriage occurred. She woke up at 2 am with intense abdominal pain and felt her womb rolling. She rushed to the toilet and found herself in a pool of blood. Her baby was gone.

For more than an hour, she continuously pushed out huge chunks of blood clots—the flesh of her unborn baby. Shalini cried. Then she went numb.

Doctors cleaned her up, but nobody bothered to heal her emotional burden—of not being able to deliver a baby successfully.

Years passed; Shalini delivered a healthy baby girl, but deep inside her, she still cries for her lost baby.

Shalini is not alone; more than one in five pregnancies worldwide end in miscarriage. While physical recovery is often addressed, emotional care is still met with silence.

The body may heal with treatment and nourishment, but internally, many women grapple with grief, anxiety, and a profound sense of loss that often goes unrecognized and untreated, said doctors, stressing the need for addressing the emotional toll.

What Is A Miscarriage?

A miscarriage is the loss of a pregnancy or the unexpected ending of a pregnancy in the first 20 weeks of gestation.

Most of them occur in 12 weeks and are classed as early miscarriages, while far fewer happen between 13 and 24 weeks.

Symptoms include

• vaginal bleeding,
• cramping like a period pain,
• decrease in pregnancy symptoms.

These occur when the fetus stops growing before 20 weeks.

As per the World Health Organization (WHO), miscarriage is the most common reason for losing a baby during pregnancy. WHO defines a miscarriage as a baby that dies before 28 weeks.

Miscarriage: Mental Health Implications

Miscarriage often causes sadness, disinterest, sleeplessness, and depression. Many times, women experience low self-esteem and guilt.

There can also be marital issues, differences in psychological reaction of the spouse, and self-blame. There is also a sense of deep personal loss and trauma. It can lead to symptoms such as

• PTSD,
• feelings of yearning,
• emptiness,
• emotional numbing.

HealthandMe spoke to some mental health experts to understand what women who face the unexplained loss suffer.

“Miscarriage in women leads to many adverse consequences in psychological, social, marital, and physical domains. Most immediate effect is an acute feeling of loss, grief, and bereavement,” Dr. Savita Malhotra, President of the Indian Psychiatric Society, told HealthandMe.

She added that women who faced miscarriage can also feel anxiety over future pregnancies.

“About 20-30 percent of women after miscarriage show clear depression and anxiety. A similar number may show PTSD. Women who have an earlier history of miscarriage, trauma, or mental illness are more prone to mental ill health,” Dr Malhotra said.

So why do women face these emotional turmoil?

"The lack of open conversation can intensify isolation, making women feel their pain is invisible or minimized. Social stigma and well-meaning but dismissive comments further deepen the wound," Dr. Chetna Jain Director Dept of Obstetrics & gynecology Cloudnine Group of hospitals, Gurugram, told HealthandMe.

Dr Deepak Raheja, a New Delhi-based psychiatrist, said that miscarriage is not just a medical event; for many women, it represents the loss of a deeply hoped-for future.

"Hormonal changes, lack of open conversations around pregnancy loss, and a tendency to internalize blame can make the emotional impact even heavier," the doctor told HealthandMe.

The experts urged the need for better familial support and good marital relationships that can prevent mental health issues in women.

Recognizing miscarriage as both a medical and emotional event is essential. Compassionate care, counselling, and supportive communities play a critical role in healing and long-term wellbeing.

Dr Malhotra said, "There's a need for clear mental health intervention and psychiatric treatment."

"It is important to recognize miscarriage as a legitimate form of bereavement," added Dr Raheja.

Compassionate care from families and healthcare professionals, along with timely psychological support, can help women process the loss more healthily and gradually rebuild emotional resilience.
