This digital era is all about catching up with trends, TikToks and reels, but at the cost of what? Many believe all of this happens at the cost of one's health and mental well-being. As a result, the grades of students, especially in high school, when they are exposed to social media the most, start to drop. However, a study based on the University of Birmingham's findings, peer-revied and published by the Lancet's journal for European health policy compared 1,277 students and the rules their 30 different secondary schools had for smartphone use at break and lunchtimes.` The study found something else, contrary to the popular belief.
The study found that banning phones in school is not linked to pupils getting higher grades or having a better mental wellbeing. The study found that a student's sleep, classroom behavior, exercise or how long they spend on their phones did not seem much different for schools with phone bans versus schools without it.
However, the study did find that spending longer time in social media or on smartphones in general may be linked to such measures. This was the first study in the world that looked at school phone rules along with the children's health and education.
In an interview to the BBC, Dr Victoria Goodyear, study's lead author said, that the findings are not against smartphone bans in school, but, a suggestion that bans in isolation are not enough to tackle the negative impacts.
The focus must be on reducing how much time the student spends on their phone, which cannot just be supervised in school.
The schools were chosen from a sample of 1,341 mainstream state schools in England. Among these the behavior of student form schools that banned the smartphones versus those who did not ban it were studied to find out that schools restricting smartphone use did not seem to see the intended improvements on health, wellbeing and focus of the student, as one would have wished to.
The study also used the internationally recognized Warwick-Edinburg Mental Well-Being Scale, a measure of mental well-being focusing entirely on positive aspects. It is a 14-item scale with 5 response categories. This method was used to determine the wellbeing of the children who participated in the research. It further looked at students' anxiety and depression levels.
It also asked from teachers about whether their students were on target, below target or above target in English and maths.
When asked students, they said that the smartphone ban forces you to hang out and chat with your friends and some of them think in lower school, it has helped them spend less time scrolling social media and making lots of friends.
Experts point out that the important part is to help students learn to use their phone in a safe and controlled space. This way, phone-related issues, especially distraction, its impact on your mental health, will be much less. The answer is not ban, but the use of the smartphone in a controlled environment, so students learn to value the "freedom" they have been given to use them at break and lunch.

A team of researchers in the US has developed a nanoparticle-based technique that could make laser surgeries for kidney stones faster, safer, and potentially reduce the chances of recurrence.
Engineers from the University of Chicago and doctors from Duke University added dark nanoparticles to a common saline solution used in kidney stone laser surgeries. Their method also promised less recurrence of disease.
The research focused on laser lithotripsy, a widely used surgical method in which lasers are used to break kidney or urinary tract stones into tiny fragments that can then be removed by suctioning or pass naturally.
Traditionally, surgeons use a small video-guided laser to fragment the stones. However, achieving effective fragmentation often requires higher laser power, which generates additional heat and causes damage to the surrounding tissues.
Thus the new method “is a way to better utilize the laser energy that is already being employed,” said Po-Chun Hsu, assistant professor at the University of Chicago Pritzker School of Molecular Engineering (UChicago PME).
Hsu noted that their nanoparticle-based “nanofluid” also has the potential to enhance the performance of lasers without increasing power levels. This will effectively fragment the stones and remove the dust particles.
The study, published in the journal Advanced Science, describes an innovative saline solution that enhances the performance of existing laser systems without requiring modifications to the equipment.
By adding dark nanoparticles that absorb laser wavelengths, the solution ensures that more of the laser energy is directed at the kidney stone rather than being reflected or dispersed.
“This improves the amount of laser energy that is transmitted to and absorbed by the stones,” said corresponding author Pei Zhong, a professor of engineering at Duke University.
“Nanofluid introduces a new dimension that can influence this complex physical process, independent of the stone composition or the laser being used,” Zhong said.
Laboratory tests using artificial kidney stones showed that the nanofluid increased stone ablation efficiency by between 38 and 727 percent in spot treatments and by 26 to 75 percent in scanning treatments.
The researchers also tested the nanoparticle solution on living cells for up to 24 hours and found it to be non-toxic and safe.
In clinical settings, however, exposure would be much shorter. Laser lithotripsy is typically an outpatient procedure lasting about 30 minutes. The researchers believe that improved laser absorption could reduce the procedure time to around 10 minutes.
“If surgeries take too long, waste heat from the laser can accumulate and cause more harm than the stone removal itself,” Hsu said.
Kidney stones are hard mineral or acid salt deposits formed in the kidneys. It occurs due to concentrated urine, and causes intense, radiating back/side pain, nausea, and blood in urine.

Former youth player of England, Amy Carr dies at the age of 35. England women's football team too paid tribute on her death. Carr was a former goalkeeper who played for England Under-17s and Under-19s. She was diagnosed with a brain tumor for a second time.
She was diagnosed in 2015 and raised more than £2,000 for charity by running the Dublin Marathon in 2024.
"We are heartbroken to hear that former England youth player Amy Carr has passed away aged 35," read a statement on the Lionesses' X account. "Amy, who was diagnosed with a second brain tumour in 2024, devoted her time to raising money for vital brain tumour research that could help others. She remains an inspiration to all."
Carr also played for Arsenal, Chelsea and Reading before she gained a football scholarship in the USA. Chelsea added on X: "We are saddened to learn of the passing of former Chelsea goalkeeper, Amy Carr. Our condolences are with Amy's friends and family at this time."
Before diving into the concept of a brain tumor, it is important to first understand what a tumor is. A tumor refers to an abnormal lump or mass that forms due to the uncontrolled growth of cells in the body.
A benign tumor consists of normal cells that have grown excessively to form a lump. This overgrowth may result from something going wrong in the body, but the cells themselves are not cancerous. On the other hand, a malignant tumor is made up of abnormal cells that grow uncontrollably. These are cancerous cells, and their aggressive nature can lead to serious health issues.
A brain tumor is a condition in which abnormal cells develop within any part of the brain. Similar to tumors elsewhere in the body, brain tumors can also be benign (non-cancerous) or malignant (cancerous). The presence of a tumor in the brain can interfere with normal brain function, depending on its size, type, and location.
Our bodies possess a natural healing mechanism that is crucial for survival. This repair system is activated whenever there is damage from injury, radiation from the sun, or harmful chemicals in the environment. However, this process can occasionally go wrong. When it does, small clusters of cancerous cells may begin to form. In most cases, the immune system successfully detects and destroys these abnormal cells before they grow. But in rare instances, these cancerous cells evade immune detection and continue to grow, leading to the formation of tumors or cancers.
Such abnormal growths can occur anywhere in the body. When these growths are located in the brain or spinal cord, they are referred to as Central Nervous System (CNS) tumors.

India is home to 25 per cent of the world's annual count of cervical cancer fatalities. According to the World Health Organization GLOBOCAN report of 2022, India reports over 120,000 new cases with nearly 80,000 fatalities. This is the highest death-toll worldwide from cervical cancer each year.
In India, a new case is diagnosed every four minutes, and another woman dies approximately every seven minutes. Persistent infection with high-risk HPV strains, especially types 16 and 18, is the leading cause of cervical cancer. Meanwhile, studies show that even a single dose of the HPV vaccine can provide long-lasting, potentially lifelong protection.
To combat this, India launched a nationwide campaign to vaccinate young girl against the human papillomavirus (HPV). This is also the second most common cancer among women in the country. India kicked off the nationwide campaign on 28 February. Prime Minister Narendra Modi at Ajmer city in the western state of Rajasthan inaugurated this campaign. Vaccines were made available free-of-cost at government facilities to approximately 11.5 million girls aged 14 years across the country.
Currently, approximately one in every 50 girls born in India is expected to develop cervical cancer during her lifetime, and widespread vaccination is likely to reduce this risk significantly," said Partha Basu, Head, Early Detection, Prevention & Infections Branch at the International Agency for Research on Cancer.
Cervical cancer develops in a women's cervix (uterus opening) due to abnormal cell growth, primarily caused by persistent HPV infection, a common infection that's passed through sexual contact.
When exposed to HPV, the body's immune system typically prevents the virus from causing damage however, in a small percentage of people, the virus can survive for years and pave the way for some cervical cells to become cancerous.
Treatment involves surgery, radiation, and chemotherapy, with early detection significantly improving outcomes, though it remains a major cancer in low-income countries Cervical cancer can also be prevented through vaccination and regular screening (Pap/HPV tests).
Cervical cancer has no symptoms in the early days and therefore, is hard to detect until it has spread. However, the early-stage symptoms include:
