Icy giant planets in the laboratory

25.03.2019

Giant planets like Neptune may contain much less free hydrogen than previously assumed. Researchers drove shock waves through two different types of plastic to reach the same temperatures and pressures present inside such planets, and observed the behavior using ultra-strong X-ray laser pulses. Unexpectedly, one of these plastics kept its crystalline structure even at the most extreme pressures. Since the icy giant interiors are made up of the same components as the plastic, planetary models may need to be partially reconsidered.

Scientist constructs artificial photosynthetic cells

25.03.2019

Scientists build artificial cells as models of primitive cells. Research team have constructed artificial cells using minimal components that are able to supply energy to drive gene expression inside a microcompartment, thus these artificial cells can produce energy that helps synthesize parts of the cells themselves. This work marks an important milestone in constructing artificial autotrophic cells, and may shed light on how primordial cells used sunlight as an energy source early in life's history.
