For millions of years, giant animals or megafauna roamed the lands that are now Australia and New Guinea. Many were like much larger versions of modern animals. There was a four-metre goanna called Megalania (Varanus priscus), for example, which likely ambushed its prey. This beast disappeared by around 40,000 years ago along with almost all the other megafauna aside from remnants such as the red kangaroo and the saltwater crocodile.

The rising and setting of the sun at Stonehenge, especially during the summer and winter solstices, continues to evoke joy, fascination and religious devotion. Now a project has been launched to delve into the lesser understood links that may exist between the monument and the moon during a rare lunar event.

Finland’s river crystals hold clues about the formation of ‘Scandinavia’s’ oldest bedrock 3.75 billion years ago. The analysis revealed that part of the crust is about 250 million years older than scientists previously thought, and that it likely originated in Greenland, according to a University of Copenhagen statement released March 21. See the study here.

Scientists studying rocks in South Africa report evidence for the earliest known earthquake triggered by plate tectonics. The temblor struck more than 3 billion years ago.

This year, the March equinox takes place on 20 March at 03:06 GMT. This means that in certain westward time zones, the equinox will actually fall on 19 March local time.

Sound waves fossilized in the maps of galaxies across the Universe could be interpreted as signs of a Big Bang that took place 13 billion years earlier than current models suggest. This research was published in The Astrophysical Journal.

The debate occurred at a packed session featuring Hairuo Fu, a graduate student at Harvard University in Cambridge, Massachusetts, who is a member of the team that found the fragments…Many scientists have said they don’t want to spend much time analysing and refuting these claims.

A pair of planetary scientists… have found evidence that the exodus of hominins out of Africa approximately 1 million years ago may have been driven by the first major glaciation of the Pleistocene. See the study here.

A comet that is larger than Mount Everest could become visible to the naked eye in the coming weeks as it continues its first visit to the inner solar system in more than 70 years, say astronomers.

A slow cosmic dance between Earth and Mars has a hidden effect on cycles in the deep ocean. According to a new analysis of the deep-sea geological record, the gravitational interaction between the two planets results in cyclic changes in deep ocean currents that recur every 2.4 million years.

Scientists have found what they believe to be the world’s earliest known fossilised forest in cliffs on the coast of South West England. The researchers say the fossil forest is about four million years older than the previous record holder in New York State.

Psilocybe mushrooms appear to have started producing psilocybin roughly 67 million years ago, right around the dinosaurs’ demise, new research shows.

Fossilized trees discovered by chance in southwest England belong to Earth’s earliest-known forest, new research has found. The 390 million-year-old fossils supplant the Gilboa fossil forest in New York state, which dates back 386 million years, as the world’s oldest known forest.

Nestled within the photosynthetic, or light-eating, tissue of the boreal trees – and within the bountiful cloud-like lichens and feathery mosses that carpet the ground between them – are fungi. These fungi are endophytes, meaning they live within plants, often in a mutually beneficial arrangement. See the research here.

Roughly 128 million years ago, snakes suddenly burst into an abundant existence on Earth, eventually diversifying into the 4,000 or so species we see today. See the research in Science.

The dismissal of a concept that has already been recognised in UN declarations and is a fundamental belief of many Indigenous communities was described by critics as shameful, contradictory and undemocratic.
