Germicidal UV lights could be producing indoor air pollutants, study finds

Many efforts to reduce transmission of diseases like COVID-19 and the flu have focused on measures such as masking and isolation, but another useful approach is reducing the load of airborne pathogens through filtration or germicidal ultraviolet light. Conventional UV sources can be harmful to eyes and skin, but newer sources that emit at a different wavelength, 222 nanometers, are considered safe.

New study unifies hypotheses behind the dietary cause of obesity that once seemed incompatible

Nutrition experts have recognized for many years that western diets rich in fats and sugar may be behind the cause of obesity, but debate has reigned over the primary culprit—intake of too many calories? Specific foods such as carbohydrates or fat? This has led to some groups recommending reducing sugar, some reducing carb intake, while others believe the key is reducing high fat-foods.

Researchers use AI to track chemotherapy complications, help families fighting pediatric cancer

In Mexico, where cancer is the second leading cause of death for children, families travel a significant distance to specialty hospitals for chemotherapy treatment. After each round of chemotherapy, children are typically sent home to recover. But when a patient leaves the hospital after treatment, there is no system to follow up on their recovery or outcome. Meanwhile, families are left without guidance on when to seek medical attention for complications.

Air pollution and breast cancer risk: A link that calls for action

Women living and working in places with higher levels of fine particle air pollution are more likely to get breast cancer than those living and working in less polluted areas. Results of the first study to take account of the effects of both residential and workplace exposure to air pollution on breast cancer risk are presented at the ESMO Congress 2023 in Madrid, Spain.
