The Canary Islands are known for their distinctive biodiversity, including many plant species found nowhere else on Earth. Researchers say invasive daisies may be doing more than simply spreading across the Canary Islands.

Antarctica is the coldest continent on Earth, featuring a deadly combination of extreme temperatures, high elevation and ice-covered terrain. The Russian Vostok Station here averages minus 55degC and on July 21, 1983, it recorded the lowest reliably measured air temperature on Earth, -89.2degC.

Mangrove forests occupy only a tiny fraction of Earth's land surface, yet they are among the planet's most valuable ecosystems. Growing where land meets the sea, these salt-tolerant trees form dense coastal forests that shield shorelines from storms, provide nurseries for marine life and lock away enormous amounts of carbon.

In the icy waters of Northeast Greenland, scientists have documented something never seen before: a rare Arctic bobtail squid living in its natural habitat while guarding clusters of eggs. Captured on high-resolution underwater video, the observation marks the first confirmed in situ record of the species, Rossia moelleri, and provides the first direct evidence that it reproduces in one of the most remote marine environments on Earth.

Oxygen levels are quietly falling across oceans, coastal waters, rivers, lakes and streams around the world, and scientists are warning that this decline deserves far more attention than it currently gets. A new review led by researchers at the University of California San Diego's Scripps Institution of Oceanography argues that aquatic deoxygenation, the loss of dissolved oxygen from marine and freshwater environments, should be formally recognised as a critical planetary process under threat, joining a select group of nine processes already used to track how close Earth is moving toward dangerous, unstable conditions.

A global review has found that more than half of migratory bird species are declining across major flyways. Researchers say the losses demand urgent cross-border conservation to protect ecosystems and essential services.

Earth rotates at about 1,670 kmph at the Equator, yet people do not feel that motion. Physics explains this through constant motion, gravity and an atmosphere that moves with the planet.

Earth's interior stores an immense reservoir of heat, yet only a handful of countries have managed to turn that energy into a major source of electricity. The reason has never been a shortage of heat beneath the ground.

At first glance, Neptune seems like the last place where violent weather should thrive. The ice giant circles the Sun at an average distance of about 4.5 billion kilometres, leaving it in a region where daylight is remarkably faint.

When planning to shift to the Moon, where would humans live? Prior to the move, one would have to carry all the cement, water and building materials from Earth and build homes first.
