The rainy season can subtly change eating habits, leading to mistakes that may affect gut health, immunity, and overall well-being. Dieticians warn against replacing balanced meals with fried snacks and refined carbohydrates, which can leave diets low in protein and fibre. Eating raw leafy greens, sprouts, and cut fruits may also increase exposure to contamination during humid weather, making lightly cooked foods a safer choice. Avoiding hygienically prepared fermented foods like curd and buttermilk may deprive the gut microbiome of beneficial support. Finally, excessive tea and coffee can replace nutritious snacks and may interfere with iron absorption. Balanced, safe, protein-rich meals remain key during monsoon.

Scientists may have uncovered a possible biological explanation for coffee’s links to healthier aging and lower disease risk. Research suggests that compounds found in coffee can activate NR4A1, a receptor involved in protecting cells from stress, inflammation, and damage. When the receptor was removed, these protective effects disappeared, strengthening its potential role in the process. Interestingly, the benefits appeared to come mainly from plant-based compounds such as caffeic acid rather than caffeine itself. The findings highlight NR4A1 as a potential cellular “switch” that could help explain some of coffee’s health associations, although further research is needed to understand how these effects translate to human health.

Researchers at the University of Hong Kong have built an AI tool called CardiOmicScore that scans thousands of proteins and metabolites in a single blood draw to predict a person's risk of six major cardiovascular diseases, including heart attack, stroke, heart failure, and atrial fibrillation, well before symptoms show up. What sets it apart from genetic risk scores, which stay fixed for life, is that it reflects a person's actual current health, lifestyle, and environment, meaning the score can shift as habits change. That makes it a potentially powerful early-warning system, giving people and doctors a real window to intervene long before disease actually takes hold. It's an exciting step toward more personalized, proactive heart care.

Diagnosing viruses like Chikungunya usually means relying on lab equipment such as PCR machines, which aren't exactly portable, but researchers at China Pharmaceutical University have developed a simple strip test that skips all that. Their method redesigns the molecular amplification process to create more bridging points for signal detection, then pairs it with gold-platinum nanoparticles that deepen the color readout, making even tiny amounts of virus visible to the naked eye. In testing, the strip matched PCR results with complete accuracy across dozens of samples and held up well in serum, saliva, and urine. Since it needs no fancy instruments, this could be a real game-changer for outbreak surveillance in clinics, ports, and remote field stations where lab access is limited.

For centuries, museums and universities have quietly stored, studied, and displayed human remains, many obtained without consent, like the 19th-century Viennese anatomist Joseph Hyrtl, who built his famous collection by paying grave robbers. The 1990 Native American Graves Protection and Repatriation Act tried to address this by requiring institutions to return remains to descendants or tribes, but progress has been slow and controversies keep surfacing, including the 2021 revelation that the University of Pennsylvania held remains from the 1985 MOVE bombing and used them in anatomy classes. Biological anthropologist Fatimah Jackson is now pushing universities and museums to confront this history and manage remains more ethically. Meanwhile, modern medical schools increasingly rely on voluntary body donation, some even holding ceremonies to honor donors, a stark contrast to Hyrtl's era.

Long COVID fatigue has left many patients with few real treatment options, but a new randomized trial involving 399 adults suggests fluvoxamine, a widely available, inexpensive antidepressant, might actually help. Participants who took the drug saw significantly less fatigue and reported a better quality of life compared to those on a placebo, marking it as one of the first medications to show a meaningful benefit for this exhausting and often dismissed condition. It's an encouraging sign for a disease that has left millions searching for answers, and given how cheap and accessible fluvoxamine already is, it could offer a practical option while researchers keep digging into what's driving long COVID in the first place.

Turns out swapping sugar for artificial sweeteners might come with a hidden cost. A new study found that adults with the highest intake of sugar substitutes experienced noticeably faster declines in memory and thinking, with cognitive aging equivalent to roughly 1.6 years faster compared to those with the lowest intake, and the effect was even more pronounced in people under 60 or living with diabetes. It's a striking association, but researchers are careful to note it doesn't prove sweeteners are the cause, just that more research is needed to sort out what's really going on. Still, it's a good reason to keep an eye on how much diet soda and "sugar-free" everything is sneaking into your daily routine.

Polycystic Kidney Disease (PKD) is an inherited disorder in which fluid-filled cysts gradually develop and enlarge inside the kidneys, potentially damaging healthy tissue over time. The disease can remain silent for years, but warning signs may include high blood pressure at a young age, persistent back or side pain, blood in the urine, recurrent urinary infections, and kidney stones. Early diagnosis through ultrasound and other imaging can help doctors monitor kidney function, control blood pressure, and slow disease progression. Although there is currently no cure, lifestyle changes and treatments such as tolvaptan may help preserve kidney function and delay kidney failure.

Fatty liver disease, now called Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD), can affect people who neither drink alcohol nor appear overweight. Doctors warn that the condition is increasingly common among Indians, including young adults and those with sedentary lifestyles. Because it often causes no symptoms in its early stages, liver damage may progress unnoticed from fat accumulation to inflammation, fibrosis, cirrhosis, or even liver cancer. The good news is that early-stage fatty liver can often be improved through weight management, regular exercise, healthier eating, and control of diabetes and cholesterol. An incidental diagnosis should not be ignored—early evaluation can help prevent serious complications.

Researchers at Texas A&M have identified two naturally occurring molecules, microRNA-15a and microRNA-16 - that can significantly slow the growth of non-small cell lung cancer cells. These microRNAs help regulate protein production and restore normal cellular balance, reducing the uncontrolled growth that drives cancer. While the discovery is not a cure, scientists believe it could become part of future combination therapies alongside surgery, radiation, or targeted drugs. The team is now exploring ways to deliver these microRNAs directly to tumor cells using engineered viral systems. This promising approach may one day help slow lung cancer progression and improve patient survival.
