Mysterious New Life Form Discovered in the Human Gut

2025-02-02

Scientists have discovered a new class of life within the human digestive system, dubbed 'Obelisks'. Unlike known viruses, Obelisks possess unique protein-coding abilities. Researchers identified at least 30,000 distinct Obelisks in roughly 10% of the human microbiomes examined, suggesting they may be colonizers of these microbiomes. Their origin remains unclear, but they all contain codes for a novel protein class called 'Oblins', differentiating them from other RNA loops like viroids. The findings, published on the preprint server bioRxiv, require further peer review.

Sugary Drinks Linked to Millions of Heart Disease and Diabetes Cases

2025-01-12

A new study reveals a shocking link between sugary drinks and millions of new cases of diabetes and heart disease annually. Over 2.2 million new diabetes cases and 1.1 million new heart disease cases are attributed to the consumption of sugary beverages each year. The problem is particularly acute in low- and middle-income countries, where these drinks are aggressively marketed and often more accessible than healthier alternatives. Latin America and the Caribbean saw nearly 24% of new type 2 diabetes cases in 2020 linked to sugary drinks, while sub-Saharan Africa experienced the highest percentage increase in diabetes cases over three decades, with sugary drinks contributing to 21% of new diabetes cases and 11% of heart disease cases. The health risks stem from the high sugar content and lack of nutritional value, leading to blood sugar spikes, weight gain, insulin resistance, and increased risk of type 2 diabetes and cardiovascular diseases. Solutions include public health campaigns, taxes on sugary drinks, and stricter advertising regulations, as seen in Mexico's successful sugar tax implementation in 2014. However, much more action is needed, especially in regions like Latin America and Africa where the impact is most severe.
