e. Live cardiac tissue containing cardiomyocytes expressing Tomm20-GFP was imaged with two photon microscopy. Raw data (left) are compared with DeAbe prediction (right) at indicated depths, with insets showing corresponding Fourier transform magnitudes. Blue circles in Fourier insets in (e) indicate 1/300 nm−1 spatial frequency just beyond resolution limit. -- Nature Communications Larger image

This illustration depicts a lake of water partially filling Mars’ Gale Crater, receiving runoff from snow melting on the crater’s northern rim. Evidence of ancient streams, deltas and lakes that NASA’s Curiosity Mars rover mission has found in the patterns of sedimentary deposits in Gale Crater suggests the crater held a lake such as this more than three billion years ago, filling and drying in multiple cycles over tens of millions of years.

All known exoplanets shown in terms of their host star’s temperature and the incident stellar flux they receive. Transiting rocky exoplanets are shown as circles, planets where only minimum mass is known as diamonds. Exoplanets in the HZ are shown in blue, with exoplanets ≤ 2 𝑅⊕ and ≤ 5 𝑀⊕ shown as smaller symbols in solid colors. Empirical HZ limits and the 3D inner HZ limit are shown as dashed lines. A light gray line indicates similar irradiation to modern Earth for different stellar temperatures. -- astro-ph.SR
