With a cut in a gene, scientists hope to eliminate high cholesterol for life

CNN Portugal6 September 2026 at 12:00

Scientists are developing a gene editing treatment with the aim of permanently eliminating high cholesterol. The approach arose from the study of a rare genetic mutation in the ANGPTL3 gene, also known as the angiopoietin-like 3 protein gene.

This gene plays a fundamental role in regulating LDL levels (the so-called "bad cholesterol") and triglycerides in the body. The identified mutation suggests that inactivating or modifying this gene could significantly reduce these lipid parameters in a lasting way. Researchers hope that through gene editing, it will be possible to replicate the protective effects of this natural mutation, offering a permanent solution for people with high cholesterol, instead of chronic treatments that require daily medication.

Mitocôndrias e quasares by António Costa: The Earth that deforms: where earthquakes meet gravity

The article explores the real shape of the Earth, questioning the idea that it is a perfect sphere. It explains that the planet's rotation, surface relief, and the uneven distribution of materials inside the Earth cause gravity to vary significantly from place to place. The geoid is presented as the scientific model that represents these gravitational variations, revealing an Earth with an irregular and deformed shape, very different from the idealized sphere.

A glaciologist warns about the impact of climate change on glacial disasters between Nepal and Tibet

A glaciologist from the University of Bristol warned about the impacts of climate change on glacial disasters between Nepal and Tibet, after the collapse of a high-altitude glacier at more than 5,000 meters on August 26, which triggered an ice and rock avalanche followed by a sudden flood. The disaster caused devastating consequences for villages, tourists, mountaineers and hydroelectric power plants, with no evidence found of a pre-existing glacial lake or artificial reservoir that had caused the event. The specialist presented initial hypotheses about the role of global warming in this type of glaciological phenomenon.

"Old person smell" really exists: science explains why (and when) it appears with age

The expression "old person smell" is real and has a scientific explanation. Studies identified that, with aging, the skin produces more 2-nonenal, a chemical compound that results from the oxidation of fatty acids on the skin's surface. This compound, which is not eliminated as easily due to changes in the lipid composition of elderly people's skin, produces a characteristic odor often described as similar to aged oil, damp cardboard, or old books. Research shows this smell is perceptible even with good hygiene, distinguishing it from odors caused by lack of cleanliness, and is linked to natural physiological changes of aging.
