In a scientific breakthrough that blurs the line between fiction and medicine, Chinese scientists have developed soft, invisible contact lenses that allow humans to see near-infrared light—a hitherto invisible spectrum to the naked eye. This innovation is not only non-surgical but also effective in complete darkness, even with the eyes closed. The results from the study, which were released in the high-profile journal Cell, represent a major advance in wearable "super-vision" technology that can potentially revolutionize medical imaging, search and rescue, and vision aid for the blind.

Human eyes are biologically restricted to detecting only wavelengths of light between 400 and 700 nanometers—a slim range that accounts for only a part of the electromagnetic spectrum. Yet, near-infrared light, from 700 to 2,500 nanometers, penetrates more deeply and harmlessly through biological tissues, holding immense promise in the fields of early disease detection and non-invasive imaging.

Directed by University of Science and Technology of China neuroscientist Dr. Tian Xue, the scientists aimed to design a lens that would be able to overcome such natural restrictions. The solution lies in rare earth nanoparticles—tiny particles with the ability to absorb invisible infrared light and re-transmit it as visible red, green, or blue light. These nanoparticles, namely sodium gadolinium fluoride doped with ytterbium, erbium, and gold, were designed to operate safely and effectively within soft contact lenses.

How These Lenses Work?

This is not the first time the research group has made infrared vision more than just a fantasy. Previously, in previous experiments, they directly injected infrared-sensitive nanomaterials into the retinas of test animals, offering them night vision for a limited time. But because retinal injections were so invasive, attention soon turned to a less invasive approach: contact lenses.

By dispersing the nanoparticles of rare earth into polymer solutions that are biocompatible with human eyes, the researchers were able to create ultra-thin, see-through lenses. The lenses were tried out in mice and then in human volunteers. Tests proved that the wearers could identify flickering infrared radiation, recognize infrared patterns, and even decipher temporal codes—even though the light itself was completely undetectable by the human eye when it is not covered by lenses.

One surprising development? Human subjects showed even stronger definition in picking up infrared light when their eyes were shut. In the opinion of Dr. Xue, "Near-infrared light penetrates eyelids more efficiently than visible light, allowing for improved signal detection with eyes shut—free from visible light interference."

Seeing What the Naked Eye Misses?

Older night-vision goggles, introduced during World War II, use electronic image intensifiers and need lots of power to run. These goggles are big, give off greenish images, and usually have difficulty identifying finer details at longer wavelengths of infrared. The newly created lenses, however, work without the need for an external power source and provide a more natural visual output. They are so light and transparent that they are potential rivals for real-life, everyday use in troublesome visual conditions such as fog, dust, or nighttime.

Can These Lenses Assist the Color Blind to See Better?

Although currently in the proof-of-concept phase, this technology's applicability is vast and extensive. The following are some of the possible uses:

Medical imaging: Increased visibility of tissues during surgery or scans

Vision enhancement: Aiding people with visual deficiencies or color blindness

Security & surveillance: Infrared pattern recognition for clandestine communication

Search and rescue: Locating persons or objects under low-visibility conditions

Anti-counterfeiting: Decoding flickering infrared security codes that cannot be seen with the human eye

For colorblind people, the group even prototyped a model of the lenses that converted components of the visible red spectrum to green or blue light, possibly allowing users to differentiate colors previously invisible to them. "This could make the invisible visible," said Dr. Xue, as he points out its possibility of improving daily life for millions.

Although its potential is great, the technology has challenges to overcome before it can be sold commercially. As of now, the lenses can pick up only intense infrared signals from LED light sources. Increasing their sensitivity to ambient or low-intensity light is a key next step. Additionally, since contact lenses are near the retina, their potential to read fine details in an image is low.

To overcome this, the scientists are developing a wearable glass system using the same nanotechnology but with greater field of vision and better image quality. The aim is to develop a hybrid wearable that offers the convenience of lenses coupled with clarity and detail for complex tasks.

This revolutionary technology is a paradigm shift in the way that humans may engage with their environment. By literally broadening the visible spectrum, the innovation provides new modes for perceiving, reacting to, and comprehending our world—particularly in situations where sight has historically been impaired.

Whether wielded by surgeons, search and rescue crews, or people moving through a blacked-out terrain, the possibilities of night-vision contact lenses are staggering. As Dr. Xue summed up, "Our research opens up the potential for non-invasive wearable devices to give people super-vision."

Obesity is no longer just a health issue, it is increasingly becoming a social phenomenon and a lifestyle disease. A recent study published in Current Developments in Nutrition, led by the Indian Council of Medical Research (ICMR) has found that 27.4% of Indian married couples share similar overweight or obese status.

Analyzing data from over 52,000 married couples across India using the National Family Health Survey (NFHS-5, 2019–21), the study points to a troubling pattern- in wealthier, urban households, especially among young couples, there is a significantly higher risk of both partners becoming overweight or obese. At its core, this research uncovers how daily habits, routines, and food choices within marriages are driving a quiet but dangerous health trend across the country.

Are Shared Habits A Risk Factor for Married Couples?

Unlike genetically linked conditions, obesity in married couples cannot be attributed to shared biology. So how does this mirroring occur? It is in environmental exposure, mutual behaviors, socio-economic context, and emotional co-regulation.

According to lead researcher Dr. Prashant Kumar Singh of ICMR’s National Institute of Cancer Prevention and Research, spousal similarities in health outcomes ranging from obesity and hypertension to smoking and sedentary behavior stem from shared lifestyles. These include eating patterns, physical activity (or lack thereof), screen time, media consumption, and stress management. Over time, habits converge especially in nuclear families with fewer social checks and less structured meal routines.

The study found that urban couples had a 38.4% concordance rate, significantly higher than rural couples (22.1%). Among the wealthiest households, this figure jumped to 47.6%, compared to only 10.2% in the poorest.

Where Obesity in Couples Is Rising Fastest In India?

Geographic disparities highlight how development and affluence correlate with rising obesity. States and territories with the highest spousal obesity concordance include:

• Kerala (51.3%)
• Jammu & Kashmir (48.5%)
• Manipur (47.9%)
• Delhi (47.1%)
• Goa (45.0%)
• Tamil Nadu (42.7%)
• Punjab (42.5%)

By contrast, states in eastern and northeastern India—where economic development is slower—showed much lower concordance rates, typically ranging from 19% to 22%.

“These figures underscore India’s uneven nutrition transition,” explains Dr. Shalini Singh, senior co-author of the study. “In wealthier regions, processed food consumption and reduced physical activity are becoming the norm. Marriage and cohabitation intensify these shared exposures, turning households into hotbeds of metabolic dysfunction.”

Is This A Disturbing Trend Among Under-30 Couples?

Perhaps the most concerning revelation is the early onset of weight gain in young couples. The study shows particularly high obesity concordance in couples under the age of 30, especially in Kerala (42.8%), Goa (37%), Jammu & Kashmir (31.6%), and Tamil Nadu (29.6%).

“This trend is alarming because early obesity increases the lifetime risk of chronic conditions like type 2 diabetes, cardiovascular disease, PCOS, and metabolic syndrome,” says Dr. Singh. “We’re seeing the impact of lifestyle-driven diseases unfold during what should be the most productive and healthiest years of life.”

The study also examined behavioral patterns that reinforce spousal weight concordance. For instance, 32.8% of couples reported regular television watching, while 39.6% reported newspaper reading, both indicative of sedentary behavior. Dependence on processed and ultra-processed food, especially in nuclear households, was another major contributor.

Interestingly, couples with similar education levels (about 45.2%) showed higher obesity concordance (31.4%), likely due to aligned food preferences, media consumption, and leisure routines.

The type of family structure also mattered. Nuclear families had a 28.9% concordance rate, higher than the 25.9% seen in joint families, where shared responsibilities and traditional food habits often foster more physical activity and balanced meals.

This Indian data fits into a much broader global trend. According to the World Obesity Atlas 2022, over 2.5 billion adults (43% of the global population) were overweight, and 890 million (16%) were obese. The burden of obesity now surpasses many infectious diseases and contributes to over 160 million years of healthy life lost annually due to comorbidities like heart disease, stroke, sleep apnea, and several cancers.

In India alone, obesity rates among adults are expected to climb significantly by 2040—27.4% of women and 30.5% of men, up from roughly 24% in 2021. If the patterns observed in married couples hold, these numbers could surge even faster than projected.

The study calls for a paradigm shift in how health interventions are designed. Rather than focusing on individuals, researchers urge a couple-based or household-level approach that takes into account the social dynamics of behavior change.

“Obesity is socially transmissible,” Dr. Singh emphasizes. “So the solution must also be social. Targeted public health messaging, fitness programs designed for couples, dietary counseling for families, and insurance incentives for preventive care at the household level are the need of the hour.”

Additionally, there’s a need to engage urban, affluent, and media-exposed demographics—who are often the earliest adopters of fast food, sedentary habits, and digital lifestyles—with interventions that feel relevant, aspirational, and sustainable.

As global health systems grapple with the rising burden of noncommunicable diseases, the Indian study offers a crucial insight: marriage can amplify risk—but also holds the key to prevention. By targeting couples early and acknowledging the influence of shared environments, public health systems can make strides in reversing obesity trends.

Veteran actor and producer Dheeraj Kumar, best known for his contributions to Hindi and Punjabi cinema, passed away at a private hospital in Mumbai on Tuesday, July 15. He was 79.

Admitted with Pneumonia, Succumbed to Organ Failure

According to sources close to the family, Kumar had been admitted to the Intensive Care Unit after being diagnosed with acute pneumonia. His health took a critical turn on Monday as he suffered multiple organ failure and was subsequently placed on ventilator support. He breathed his last around 11 AM on Tuesday, with his son by his side in his final moments.

A Career That Began With a Talent Contest

Dheeraj Kumar’s journey into the world of entertainment began in the mid-1960s, when he participated in a talent contest that also featured Rajesh Khanna and Subhash Ghai. In a 2012 interview with The Hindu, Kumar recalled:

“In a talent contest in Mumbai in the 1960s, three were selected to be actors among some 10,000 aspirants — Rajesh Khanna, myself and Subhash Ghai... He became a superstar.”

Kumar went on to act in several films, including Rakhwala, Tyaag and Sargam, and shared screen space with many leading actors of the time. Over the years, he transitioned into television production and was known for creating popular shows such as Om Namah Shivay and Shree Ganesh. His last known collaboration with Rajesh Khanna was a TV series in 2019.

Understanding Pneumonia and Its Risks

As per the American Lung Association, pneumonia is an infection that causes inflammation in the air sacs (alveoli) of one or both lungs. These air sacs may fill with fluid or pus, leading to symptoms that range from mild to life-threatening. Acute pneumonia, in particular, can cause sudden and severe respiratory symptoms.

Some of the common symptoms include:

• Persistent cough with yellow, green, or bloody mucus
• High fever, sweating and chills
• Shortness of breath and chest pain while coughing or breathing
• Fatigue, nausea or vomiting
• Confusion, especially in older adults

Kumar’s condition is a reminder that pneumonia can escalate quickly, especially in older individuals or those with weakened immune systems.

Can Pneumonia Be Fatal?

Yes, pneumonia can be deadly—especially when left untreated or when it occurs in high-risk individuals. According to global estimates, as noted by the American Lungs Association, over 1.8 million people die from pneumonia each year, with children under five in low-income countries being the most vulnerable. In older adults, complications such as respiratory failure, sepsis, or organ failure often lead to death.

Bacterial pneumonia is more likely to require hospitalization, but viral and fungal forms can also be life-threatening. Vaccines such as the pneumococcal vaccine and flu shots can significantly reduce the risk of infection, particularly in older adults.

Maintaining overall health, timely vaccinations, and early medical intervention are critical in preventing complications.

After Jannik Sinner's news of anti-doping test, British tennis player Tara Moore is also making news. The 32-year-old was Britain's top ranked women's doubles player when she was provisionally banned in May 2022. Again, she has been banned for four years for a doping offence, though she had been cleared for the same by an independent tribunal just 18 months ago.

She was tested positive for nandrolone and boldenone at a tournament in the Colombian capital Bogota the previous month.

The reason Moore provided was due to the ingestion of contaminated meat. While in December 2023, an independent tribunal ruled that contaminated meat was the reason that the test came positive and Moore "bore no fault or negligence"; the International Tennis Integrity Agency (ITIA) thinks otherwise.

ITIA has been upheld by the Court of Arbitration for Sport (Cas). In the March hearing, Cas said in a media release: "After reviewing the scientific and legal evidence, the majority of the Cas panel considered that the player did not succeed in proving that the concentration of nandrolone in her sample was consistent with the ingestion of contaminated meat."

This means Moore will not be free to play again until the start of 2028 season. "The panel concluded that Ms Moore failed to establish that the ADRV (Anti-Doping Rule Violation) was not intentional. The appeal by the ITIA is therefore upheld and the decision rendered by the Independent Tribunal is set aside."

The ITIA chief executive Karen Moorhouse told BBC,"For the ITIA, every case is considered according to the individual facts and circumstances. In this case, our independent scientific advice was that the player did not adequately explain the high level of nandrolone present in their sample. Today's ruling is consistent with this position."

What Do Nandrolone Decanoate And Boldenone Do To You?

Nandrolone Decanoate: As per a 2020 study published in journal Medicina, nandrolone decanoate is an androgen, which means it plays a significant role in the development of male reproductive organs. The study notes: "The clinical use of synthetic testosterone derivatives, such as nandrolone, is focused on maximizing the anabolic effects and minimizing the androgenic ones." The study also mentions that apart from its clinical use, skeletal muscles can be considered as the primary target tissue. "Nowadays, especially athletes in power sports such as bodybuilding and weightlifting administer illegally high doses of Anabolic Androgenic Steroids (AAS) to increase their muscle mass and improve their overall performance," notes the study.

Nandrolone Decanoate injections have been classified under the Anabolic Steroids Control Act of 1990 and due to its serious health risks, it is banned by most sports organization and is also listed in the prohibition list by the World Anti-Doping Agency (WADA).

Side Effects Include:

• Infertility
• Liver Toxicity
• Impaired Lipid Profile
• High Blood Pressure
• Acne
• Hair Loss
• Gynecomastia

Boldenone: As per a 2016 study published in the Journal of Food and Drug Analysis, this AAS can be used in repairing wasting of the body caused by some emaciating disease. It can also be used for human sports for better performance and promoting the growth of skeletal muscle.

However, this is also used for increasing the body weight in livestock as growth-promoting agents. This is also one of the matters the study looks into, in order to "evaluate the safety and meat quality criteria in broilers following intramuscular injection of boldenone." This is the reason Moore too used in her defense, that the result of her positive test was contaminated meat.

The US Anti-Doping Agency (USADA) notes that there is no therapeutic or medical use for boldenone in humans. More specifically, it is not approved by the Food and Drug Administration (FDA) for use in humans for any reason. It also notes that WADA has included boldenone in its prohibited list. Since it could occur naturally at very low concentrations in the urine, WADA-accredited laboratories apply a specific analysis procedure called carbon isotope ratio mass spectrometry, or GC/C/IRMS, to differentiate between external administration and internal production.

What are the side effects? USADA notes that in men, boldenone causes decreased testosterone production and impacts the reproductive system and fertility of males. It also impacts the size of the testes, lower sperm count, and sperm mobility.
