Venus is a terrestrial planet with rocky terrain,  volcanoes, and a dense atmosphere. Carbon dioxide and sulphuric acid-laden clouds dominate the atmosphere. Also, the dense atmosphere gives rise to excruciating surface pressures of 92 bars (as much as that at 1km below sea level on earth), making the planet inhospitable.

Researchers have shown that two receptors previously known as ‘silent receptors’ are not truly silent and that they signal via a different mechanism than was expected.
