All land plants originated from a single evolutionary event when freshwater algae got a foothold on land, giving rise to an astonishing biodiversity of plants on earth. However, the group […]

Plants Evolved Ability To Actively Control Water-loss Earlier Than Previously Thought
New research has shed light on when plants first evolved the ability to respond to changing humidity in the air around them, and was probably a feature of a common […]
![Radius of observed planetesimal belts as a function of host star luminosity (black and white points with error bars). The white shaded region represents the ±1σ range of power laws (about the best fit) allowed by the data, including the intrinsic scatter as well as the uncertainty in the observed radii. The background colour map represents the selection probability (%), or percentage of belts that would pass the selection effects at a given [R-L⋆] location, assuming unobserved belts have the same distribution of parameters [d,RBB/R, M, λ0, β] as the observed population. -- astro-ph.EP](https://i0.wp.com/astrobiology.com/wp-content/uploads/2025/02/REsolved-ALMA-and-SMA-Observations.png?resize=1200%2C720&ssl=1)

Arrival Of Land Plants Changed Earth's Climate Control System
The arrival of plants on land about 400 million years ago may have changed the way the Earth naturally regulates its own climate, according to a new study led by […]

Earth Plants Colonized Land 100 million Years Earlier Than Previously Thought
For the first four billion years of Earth’s history, our planet’s continents would have been devoid of all life except microbes. All of this changed with the origin of land […]

Does Eclipse Equal Night In Plant Life?
On August 21, 2017, about 215 million American adults watched one of nature’s most dramatic events: a total solar eclipse. However, most of the country could only see a partial […]

Plants Appeared On Land Earlier Than Previously Thought
Plant biologists agree that it all began with green algae. At some point in our planet’s history, the common ancestor of trees, ferns, and flowers developed an alternating life cycle–presumably […]

Glowing Plants Are A Sign of Health
Radiant skin is considered a sign of good health in humans, but plants also glow when they are well. A potential new ESA satellite could use this fluorescence to track […]
