What does Mars’ lake mean for the search for life on the Red Planet?

The search for life on Mars just got a lot more interesting. For decades, scientists have looked at the dry and dusty planet and focused on finding regions where life could have taken root billions of years ago, when the Martian climate was warmer and wetter. But on July 25, researchers announced they had spotted signs of a large lake of liquid water hiding beneath thick layers of ice near the Red Planet’s south pole.

Life rebounded just years after the dinosaur-killing asteroid struck

When a 10-kilometer-wide asteroid hit the Gulf of Mexico 66 million years ago, it drove over 75% of Earth’s species to extinction, including the dinosaurs. But within just a few years, life returned to the submerged impact crater, according to a new analysis of sediments in the crater. Tiny marine creatures flourished thanks to the circulation of nutrient-rich water.

Malaria may weaken the skeleton

Malaria parasites leave a trail of destruction in an infected person’s body. The microscopic invaders massacre red blood cells, produce harmful chemicals, and sometimes damage the brain. A new mouse study suggests that the parasites can also weaken bones. If they do the same in people, they could stunt the growth of children infected with the disease.
