A team of researchers from the National and Kapodistrian University of Athens has discovered a completely new genus and species of subterranean freshwater snail in the Peloponnese region of southern Greece. The species, Cyllena hermes, is a small, unpigmented, eyeless aquatic snail fully adapted to life underground.

Due to artificial irrigation and rising temperatures, the concentration of salts (including sodium chloride, or "table salt") is increasing in soils worldwide. This is not only an environmental problem but also a challenge for agriculture. For example, increased salinity can disrupt the water balance of most plants (known as glycophytes) or even lead to their death, including crops.

Scientists have discovered that marsupial forelimbs (arms) develop much earlier before birth than previously thought, providing new insights into evolutionary innovation and biology.
