At the Wolong National Reserve in Sichuan, things are different
the reserve focuses on preparing select cubs for release into protected wilderness. This
"rewilding project" aims to minimize human contact using costumes, so the pandas don't grow dependent on people and can survive independently in the wild

New research suggests that Mars may play a subtle role in shaping long-term climate patterns on Earth. Scientists have long understood that ice ages are influenced by gradual changes in Earth’s orbit and tilt—known as Milankovitch cycles which affect how sunlight is distributed across the planet over tens to hundreds of thousands of years.
Using advanced simulations of the solar system, researchers explored what would happen if Mars were removed. Without it, a key about 100,000-year cycle linked to the timing of ice ages weakened significantly, while other cycles driven by planets like Jupiter and Venus remained largely unchanged. This points to Mars as an important contributor to one part of Earth’s long-term climate rhythm.
Although Mars is much smaller than Earth, its gravity still has an effect over vast timescales. Its orbit gently influences the shape of Earth’s orbit called eccentricity, which in turn affects how solar energy is distributed across the planet. These changes are small, but over millions of years they can help determine whether ice sheets expand or retreat.
The findings highlight how interconnected planetary systems can be. Mars isn’t responsible for ice ages on its own factors like greenhouse gases, oceans, and the atmosphere remain dominant-but it appears to be one piece of a much larger, complex system influencing Earth’s climate.
