Fruit flies reveal new insights into space travel’s effect on the heart
Scientists at Sanford Burnham Prebys Medical Discovery Institute have shown that fruit flies that spent several weeks on the International Space Station (ISS)—about half of their lives—experienced profound structural and biochemical changes to their hearts.

Chirality is a type of asymmetry where something can’t overlap with its mirror image, like our hands. Michael Ostap, Ph.D., is researching what causes chirality on a molecular level to better understand embryonic development and how it can go wrong.

What Induces Sleep? For Fruit Flies It’s Stress at the Cellular Level
Sleep-deprived fruit flies helped reveal what induces sleep. University of Oxford researchers Anissa Kempf, Gero Miesenböck, and colleagues reveal that fruit fly sleep is driven by oxidative stress, the imbalance of free radicals and antioxidants in the body.
