It is a well-known fact that Alzheimer's disease is a neurological condition that is characterized by the loss of neurons and, thereby, the loss of communication between them. Until now, not much was known about the exact way in which these neurons die. However, pioneering new research has shed some light on the exact way that brain cells die in Alzheimer's.
The research, led by Professor Bart De Strooper at VIB-KU Leuven and UK Dementia Research Institute (UK DRI) at UCL, along with Dr Sriram Balusu at VIB-KU Leuven, sheds light on a long-standing mystery in neuroscience.
For years, scientists have debated how neurons perish in this condition. This latest research identifies necroptosis, a programmed form of cell death, as a key mechanism activated in response to amyloid plaques and tau tangles—two hallmark proteins linked to the disease. Importantly, the researchers not only identified this process but also demonstrated that preventing it could rescue neurons, paving the way for new therapeutic strategies.
A crucial player in this process is an RNA gene called MEG3. The study found that MEG3 levels were significantly elevated in human neurons affected by Alzheimer’s, and its presence alone was sufficient to trigger necroptosis. These findings mark a significant advancement in understanding the cellular mechanisms driving neurodegeneration in AD.
One of the major challenges in Alzheimer's research has been linking the disease's defining characteristics—amyloid plaques, tau tangles, and neuron loss—in a way that accurately represents disease progression. Traditional mouse models have failed to replicate these features, leaving critical gaps in knowledge.
To overcome this limitation, the research team developed a novel model by implanting both human and mouse neurons into the brains of AD mouse models. Strikingly, only the human neurons displayed the classic features of Alzheimer’s, including tau tangles and significant cell loss. This suggests that human-specific factors play a crucial role in the disease, which standard animal models cannot replicate.
"Our findings underscore the resilience of mouse neurons against amyloid pathology, opening doors to understanding protective mechanisms that might inspire future treatments," explained Sriram Balusu, the study's first author.
With their new model, researchers probed deeper into how neurons die in Alzheimer’s. They confirmed that necroptosis plays a central role in neuronal loss. More significantly, they found that by reducing MEG3 levels and blocking necroptosis, they could prevent neuron death. While further research is needed to clarify how MEG3 triggers this process, the discovery represents a major step forward.
Professor De Strooper emphasized the potential impact of these findings:
"Necroptosis is already being explored in drug development for cancer and ALS. Our research opens up new possibilities for targeting Alzheimer’s through this pathway, alongside conventional approaches focusing on amyloid and tau."
As Alzheimer’s continues to affect millions worldwide, this discovery offers a promising direction for future treatments. By targeting necroptosis and the role of MEG3, researchers may be able to slow or even halt neurodegeneration, bringing new hope to patients and their families.

While medications are made to have a certain effect on one’s body, everyone’s body is built differently. What may work on one person may not have the same effect on others. Different eating habits, lifestyle choices and other factors can enhance or decline the effect of medication.
One such anomaly that researchers have found is a particular spice. A new study found that consuming this spice can change the way medication reacts to your body. Published in the Food Chemistry: Molecular Sciences journal, researchers have found that cinnamon is a key ingredient in the way one’s body processes medicine. While some cinnamon is good for your body, a lot of it could stop your body from using certain drugs properly.
Researchers in this study wanted to understand exactly how cinnamon and the important parts of it affect the way our bodies break down medicines. To do this, they did experiments that copied how our stomachs digest food. They looked closely at cinnamon oil and two main things it contains: cinnamaldehyde and cinnamic acid. The study showed that both of these things can turn on special sensors in our bodies called xenobiotic receptors. These sensors are important for controlling how we deal with drugs.
Researchers explained the activation of these receptors by excessive cinnamon intake could lead the body to eliminate some drugs too rapidly, meaning, it could make our bodies get rid of some medicines too quickly. If this happens, the medicines might not stay in our bodies long enough to do their job properly, making them less effective. So, while a little cinnamon might be good for you, using too much could actually make some of your medications not work as well as they should.
The researchers pointed out that even though a small amount of cinnamon in your food is probably okay, using a lot of it regularly or in strong forms could be a problem. They specifically warned that cinnamon supplements, which have a much higher amount of cinnamon in them, might be more likely to cause these issues with your medicines. Because of this, the researchers strongly advise people to talk to their doctors before they start taking any cinnamon supplements or similar products to be safe.
As the popularity of cinnamon grew researchers wanted to bring this issue to the forefront. A lot of people like type 2 diabetes patients who benefit from cinnamon. According to a study published in the American Diabetes Association 2003, one three and six grans if cinnamon per day reduced the amount of serum glucose, LDL or bad cholesterol and total cholesterol in people with type 2 diabetes, effectively lowering risk of cardiovascular diseases and other conditions linked with diabetes.
As many people become aware of the health benefits of cinnamon and start incorporating it in their diet, it is important to do more research to find out what side effects it could have and how it could potentially affect our health. While this new study gives us some important information, the researchers say we still need to do more research, especially studies with people, to really understand how cinnamon might interact with different medications.

Showering every day has been a matter of discussion. But you will always find someone who has gone a day or two without a shower. While it is generally not considered unhygienic, dermatologists have now raised concerns about this habit.
There are always red flags which are sent by your skin if you miss bathing. Some of you may experience scaly patches or discoloured parts. It may even start to look dirty because of hyperpigmented spots. It's not dirt, though. If you reach that point, you might want to see a dermatologist right away, who can determine if you have dermatitis neglecta.
The answer lies in how your skin sheds. Every few weeks, all dead cells are removed. Cells slough off. Showering helps this process along, even if you don't use an exfoliant. Therefore, when you aren't showering, those cells are likely to remain on the upper layer of your skin or epidermis. If left for days, it will naturally combine with all the bacteria, sweat, oils, and grime your skin encounters. And a layer of tough buildup will begin to appear.
Dermatitis neglecta does not happen overnight or even in a couple of weeks. A 2015 study in the Journal of Dermatology explored three cases. In one of the cases, the affected individual had not cleaned a part of her body for no less than three to four months. (As a side note, the woman had gone through surgery and was worried about causing an infection in the area, which is why she stopped washing it.) Fortunately, the skin treatment for dermatitis neglecta is fairly simple. Most people can resolve skin issues that are related to dermatitis neglecta with regular cleaning and, in stubborn or severe cases, alcohol-based wipe-downs or administration of topical agents.

There are many conditions that can affect a woman’s reproductive health. Certain medications or conditions that need hysterectomy can cause early menopause in women. There are many likely reasons why this happens. According to Office on Women’s Health (OASH) family history, smoking, chemotherapy or pelvic radiation or autoimmune conditions like thyroid disease and rheumatoid arthritis, could be some of the reasons why some women go through early menopause.
However, a new study shows that endometriosis could also be a reason for early menopause in women. The study published in the Human Reproduction journal found that women with endometriosis are seven times more likely to undergo surgical menopause, which involves the removal of both ovaries, compared to women without the condition. Furthermore, they are twice as likely to have this surgical procedure before the age of 40.
Women with endometriosis face a greater risk of experiencing natural menopause earlier than others. They are 1.4 times more likely to enter natural menopause before the age of 40, a stage defined as premature menopause. These women also have an elevated risk of early menopause, occurring between the ages of 40 and 44.
It is a persistent condition affecting approximately one in 10 women of reproductive age in the UK. According to the NHS, it involves tissue similar to the womb lining appearing in other parts of the body. Previous research has shown a significant delay of nearly nine years in receiving an endometriosis diagnosis, potentially leading to missed treatment opportunities and irreversible organ damage due to the continued growth of this misplaced tissue.
According to the World Health Organization, 190 million women throughout the globe have endometriosis, which is roughly 10% of people. Not only does it cause pain during periods, issues in bowel movements, urination etc., but also causes bloating nausea, fatigue and mental health issues like depression, anxiety and infertility.
It's crucial for women with endometriosis to be aware not only of the wide range of debilitating menopause symptoms they might experience earlier in life but also of the broader health risks associated with premature menopause, whether it occurs naturally or is surgically induced. These risks include cardiovascular disease and premature death.
Researchers from the study stressed the importance of understanding the causes of early or medically induced menopause to implement proactive measures for managing the associated long-term health risks.
OASH explains that women who experience menopause early may face similar symptoms and health issues as those going through regular menopause. However, some women with early or premature menopause might also have a greater chance of developing serious health problems like heart disease and weak bones (osteoporosis) because they'll live for a longer time without the protective benefits of higher estrogen levels.
They might also have more intense menopause symptoms, and there are treatments available to help manage these if they interfere with daily life. Additionally, some women may feel sad or depressed about losing their fertility early or the changes in their bodies. If these feelings, like low energy or loss of interest in enjoyable activities, last for more than a few weeks, speaking to a doctor is recommended.
