We summarize the week's scientific breakthroughs every Thursday.

Growing need for space trash collectors
On April 2, for the fifth time in less than three years, the International Space Station fired its engines to dodge a piece of orbital debris that appeared on a collision path. Other spacecraft also regularly scoot out of the way of rocket and satellite debris. Such evasive action will be needed increasingly frequently, a new study finds.
- Planetary Science
White dwarfs gobble Earthlike treats
Astronomers have found elements in the dead stars’ atmospheres that suggest rocky planetary bodies once orbited the stars.
- Physics
Particle physicists chasing ghosts
Wispy neutrinos could one day explain why matter dominates the universe.
- Chemistry
Meteorites contain chemicals linked to life
Space rocks could have delivered DNA building blocks to Earth.
