How flowering plants conquered the world

Scientists think they have the answer to a puzzle that baffled even Charles Darwin: How flowers evolved and spread to become the dominant plants on Earth.

Flowering plants, or angiosperms, make up about 90% of all living plant species, including most food crops, according to BBC.

In the distant past, they outpaced plants such as conifers and ferns, which predate them, but how they did this has has been a mystery.

New research suggests it is down to genome size - and small is better.

Special star is a Rosetta Stone for understanding the sun's variability and climate effect

The spots on the surface on the Sun come and go with an 11-year periodicity known as the solar cycle. The solar cycle is driven by the solar dynamo, which is an interplay between magnetic fields, convection and rotation. However, our understanding of the physics underlying the solar dynamo is far from complete. One example is the so-called Maunder Minimum, a period in the 17th century, where spots almost disappeared from the surface of the Sun for a period of over 50 years, according to Science Daily.
