Cigarettes with ultralow nicotine levels are now being called the game-changer in the fight against smoking. If you are having trouble in quitting smoking, then, it is for you, that soon the Biden White House is expected to formally propose a plan that will order cigarette nicotine levels to be reduced, reports The Washington Post. For now though, it has been a failure, as these cigarettes, also known as VLN cigarettes that stands for very low nicotine are only available in 5,100 stores in 26 states. This is a very small fraction of the overall market for cigarettes. The company that makes it, 22nd Century, is struggling not because of the low supply, but also from the advocates who have long believed slashing nicotine levels altogether.
Nicotine is a chemical that is produced naturally from tobacco that makes the cigarette and also keeps people hooked. While it is believed that it makes people alert, and get the "hit" to keep them going, it exposes the users to harmful substances, carcinogens, and increases the risk of heart disease, lung cancer, and other illness.
Ultralow-nicotine cigarettes, like the VLN brand, contain about 95% less nicotine than the regular cigarettes. The idea is quite simple: without the addictive grip of nicotine, smokers will find it easier to quit. Research too has shown some promise. For instance, the studies funded by the National Institute on Drug Abuse revealed that very low nicotine cigarettes reduced addiction potential significantly without having users to increase their smoking frequency. However, the problem is, why would anyone choose for a low-nicotine that does not make them feel the same way, when the high-nicotine cigarette is right next to it, making them feel the same way, with the same alertness, sold at the same price.
“It’s very hard to imagine someone actively choosing to continue to use a low-nicotine product for the same price when a high-nicotine product is right next to it,” said Eric Donny, a Wake Forest University School of Medicine nicotine researcher.
No wonder, the experiment with low nicotine product by Philip Morris' Next cigarettes in the 1980s and Vector Tobacco's Quest brand in the early 2000s, flopped.
The Food and Drug Administration (FDA) has supported the development of such products, even allowing VLN cigarettes to be marketed as lower-risk options. However, these products remain a niche market, available in only a fraction of U.S. stores.
Recently, the Biden administration has considered a bold step—mandating a dramatic reduction in nicotine levels for all cigarettes sold in the United States. Supporters believe this move could save millions of lives, while critics, including tobacco companies, warn of potential unintended consequences.
Resistance from Big Tobacco Companies: They could argue that slashing nicotine levels could backfire. Their claim is, smokers will turn to black markets or smoke more to satisfy their cravings, which may lead to greater exposure to harmful substances.
Consumer Reluctance: History is proof to the instances of smokers being hesitant to embrace the low-nicotine products.
Political Hurdle: It may face political roadblocks, as under the Trump administration, plans to cut nicotine were shelved.
Advocates believe that ultralow-nicotine cigarettes could be a game-changer, comparing them to decaf coffee or non-alcoholic beer—products that reduce harm while offering a similar experience.
Some experts warn that a black market for traditional cigarettes could undermine these efforts. They also stress the need for safer alternatives, such as vaping products, to support smokers transitioning away from traditional cigarettes.

Millie Bobby Brown has built an impressive career, all while quietly managing a few health concerns along the way. From becoming a household name through Netflix’s hugely popular Stranger Things to leading films like Enola Holmes, the Gen Z actor (now a married mother of one) has made a strong mark in Hollywood. What many people may not realise is that her work has, at times, been shaped by a hearing-related condition. Brown has lived with hearing loss for most of her life, a fact that often goes unnoticed.
Brown first spoke publicly about her hearing condition in a 2017 interview with Variety, where she shared that she has had hearing loss in one ear since birth. Even early in her career, she was clear that she would not allow it to stand in the way of her passion for performing. “I just started to sing, and if I sound bad I don’t care, because I’m just doing what I love,” she said at the time. “You don’t have to be good at singing. You don’t have to be good at dancing or acting. If you enjoy it and it makes you happy, you should do it.”
While Brown rarely focuses on her hearing loss, she has spoken about how it affects her daily life. In a conversation with Call Her Daddy host Alex Cooper, she explained that certain sounds, like loud chewing, do not bother her because she can mostly hear herself when she eats. She also shared that her husband, Jake Bongiovi, whom she married in 2022, sometimes jokes that she has “selective hearing.” In reality, she says sounds often feel “muffled, like being underwater.” Brown admitted that she does miss important moments, including hearing directors call out “action” or “cut” on set.
Unilateral hearing loss happens when hearing is affected in one ear while the other ear functions normally. Even with hearing in one ear, this condition can make it difficult to understand speech clearly and to identify where sounds are coming from.
The level of hearing loss in one ear can range from mild to severe. When there is little to no hearing at all in one ear, it is described as severe or profound hearing loss, also known as single-sided deafness. Unilateral hearing loss may be present at birth, develop gradually, or appear suddenly. Depending on the cause, options such as hearing aids or cochlear implants may help improve hearing, according to the Cleveland Clinic.
Many symptoms of unilateral hearing loss are similar to those seen with hearing loss in both ears. You may:
Doctors do not yet fully understand all the reasons why hearing loss occurs in just one ear. Causes can differ between adults and children. In children, hearing loss may be linked to genetics or infections. Possible causes include:
According to the American Academy of Audiology, treatment depends on the underlying cause and the severity of the hearing loss. Available options may include:

In what researchers are calling an important scientific advance, a team in the US has shown through animal experiments that Alzheimer’s disease may be reversible, overturning a belief that has shaped medical thinking for more than 100 years. For generations, the neurodegenerative condition was considered permanent and progressive. The findings, published in Cell Reports Medicine, are based on multiple preclinical mouse models as well as examinations of human Alzheimer’s brain tissue.
The study found that preserving a healthy balance of NAD, a molecule central to cellular energy production, could both prevent and reverse Alzheimer’s-related damage. NAD plays a key role in brain function and is now seen as a major contributor to the disease process. Researchers also observed that NAD levels drop much more sharply in the brains of people with Alzheimer’s, a pattern that was mirrored in mouse models of the condition.

“We were extremely encouraged by what we observed,” said Andrew A. Pieper, the study’s senior author and Director of the Brain Health Medicines Center at the Harrington Discovery Institute, University Hospitals, as per Sciencedirect. “By restoring the brain’s energy balance, we saw both structural and functional recovery in mice with advanced Alzheimer’s.”
Pieper noted that the effect appeared consistently across two very different mouse models, each driven by separate genetic mechanisms linked to Alzheimer’s in humans. “Seeing recovery in models caused by distinct genetic pathways strengthens the case that restoring NAD balance in the brain could have real therapeutic potential for patients,” he said.
For the study, researchers examined mice engineered to carry genetic mutations known to cause Alzheimer’s disease in people. One group of mice carried multiple human mutations affecting amyloid processing, while the second group carried a human mutation in the tau protein.
After confirming that brain NAD levels dropped sharply in both human Alzheimer’s tissue and mouse models, the team tested whether stopping this decline before symptoms appeared could prevent disease, and whether restoring NAD levels after the disease had progressed could reverse it. To do this, they used a well-studied drug called P7C3-A20 to restore NAD balance in the brain.
The results were striking. Not only did maintaining NAD levels prevent Alzheimer’s from developing in mice, but starting treatment later, after the disease was already advanced, allowed the brain to repair the main pathological damage caused by the genetic mutations. In both mouse models, cognitive abilities were fully restored.
In Alzheimer’s disease, NAD, short for nicotinamide adenine dinucleotide, is an essential coenzyme whose levels naturally decline with age. This decline disrupts energy production, mitochondrial health, DNA repair, and the ability of neurons to withstand stress. Research suggests that increasing NAD levels, often through precursors such as nicotinamide riboside, may reverse Alzheimer’s-related damage, improve memory, and correct abnormal RNA processing in animal models. Because of this, NAD has become a major area of focus for developing new Alzheimer’s therapies, according to the National Institutes of Health.
The findings also pave the way for further research and eventual testing in people. The technology behind the treatment is currently being developed for commercial use by Glengary Brain Health, a Cleveland-based company co-founded by Dr. Pieper.
“This recovery-based treatment approach now needs to be tested in carefully designed clinical trials to see if the benefits seen in animals can be replicated in humans,” Pieper said.
He added that future laboratory work will focus on identifying which components of brain energy balance matter most for recovery, exploring additional strategies that could complement this approach, and determining whether similar methods could work for other long-term, age-related neurodegenerative diseases as well.

Adenovirus, or what some people are calling the mystery disease is going to be the next worry in the UK, after superflu had already grappled the healthcare system. Along with H3N2 and its variant superclade K, people are now worrying about this mystery disease.
Adenovirus is highly contagious and causes mild cold or flu-like symptoms, though severe cases could lead to stomach flu and vomiting. Many describe this virus as 'heartier' than others. The reason is that the virus can survive longer on surfaces and even resist the common disinfectants used. This is what makes it highly transmissible.
As of now, there is no treatment for adenovirus, it could however be managed and monitored. What helps is regular handwashing and thorough cleaning of surfaces.
The good news is that cases of adenovirus are actually dropping in the UK, as confirmed lab reports. The cases last week were 1.2 per cent, whereas the week prior, it was at 1.7 per cent, as also reported by the Independent.
While a lot of the symptoms mimics of those in flu or COVID, including shortness of breath, a sore throat and or a runny nose. However, there are certain unique symptoms of adenovirus that include:
Other rare symptoms could also include impact on your bladder or nervous system. As viruses in your bladder can also cause urinary tract infections, and the same virus in your nervous system can cause condition that can affect your brain. These conditions also include encephalitis and meningitis.
The symptoms usually start to subside within two days, however, if the symptoms stay even after three days without any relief, it might be a red flag. The best thing to do during such a situation is to go consult your GP.

Experts have noted that due to its ability to stay longer in the environment and being highly transmissible, it is in fact, spreading faster than flu and COVID. Eric Sachinwalla, Jefferson Health's medical director said that this virus is still unfamiliar and thus not much can actually be done to treat adenovirus. Speaking to PhillyMad, he said, "It is pretty contagious because it is heartier than other viruses - soap and water, or everyday disinfectant, won't kill it, so it tends to live in the environment longer."
Since adenovirus spreads through close contact and is resistant to many everyday disinfectants, hygiene remains the key. The best way to stay safe is by avoiding close contact, especially with those who are unwell. You may also keep an eye on your symptoms, including your body temperature and take steps to prevent the virus from spreading by taking precautions, as well as getting the flu jab.
