On the origin (and fate) of plants that never bloom

A study by Kobe University reveals that plants reproducing solely through self-pollination likely arose from populations with extremely low genetic diversity. The research found that these species are highly successful at producing fruit and may have an evolutionary edge over outcrossing, raising questions about their long-term viability.

1.5°C Paris Climate Agreement target too high for polar ice sheets and sea level rise

A new study suggests that limiting global temperature increase to 1.5°C may not be enough to save the world's ice sheets, which could lead to significant losses and extensive displacement of coastal populations. The researchers argue that a target of around 1°C would be more effective in preventing rapid sea level rise.
