The increase in carbon dioxide in the atmosphere is also being detected in human blood

A pair of scientists discovered that average blood bicarbonate levels in humans have increased by approximately 7% since 1999, a phenomenon that reflects the rise of carbon dioxide in the atmosphere. Bicarbonate (HCO3), which is a byproduct of the body's metabolism, serves as an indicator of CO2 concentration in the blood, demonstrating that air pollution is having measurable impacts on human physiology.

Eyes on the sky: last partial lunar eclipse of the year happens this early morning

Portugal may observe in the early morning of this Friday, August 28, the last partial lunar eclipse of the year. The phenomenon, which occurs when the Moon partially crosses the shadow projected by Earth, will begin at 2:23 AM with the entry into Earth's penumbra, and the most visible partial phase will begin at 4:12 AM. Earth's shadow will cover part of the lunar surface, altering the appearance of the lunar disk, with the peak of the eclipse occurring near sunrise.

Lunar eclipse, the dive into emotions</minimax:tool_call>, and may return in the future. The text discusses how a lunar eclipse affects emotions and energy, encouraging introspection and emotional release.

The article describes the lunar eclipse that occurs today, explaining the scientific phenomenon behind the "Blood Moon" — when Earth positions itself between the Sun and the Full Moon, casting its shadow (umbra) on the satellite while sunlight passes through Earth's atmosphere, dispersing the blue tones and leaving only the warmer frequencies that give the reddish hue. The author invites readers to take advantage of this moment to deeply reflect on their emotions.
