Busting the notion that modern-day parents are the first ones to keep tabs on their children to safeguard them from potential dangers, a new study has claimed that the practice began as long as 430 million years ago.

Published Monday in the Proceedings of the National Academy of Sciences, the study described a tiny, resourceful arthropod creature, Aquilonifer spinosus, which devised a unique way for baby tracking. Aquilonifer spinosus tethered egg pouches to its back with threads and followed its juveniles as they grew, in a similar manner as if they were tiny kites. The aim was to keep the young ones tethered to the adult’s body with strings so as to keep them safe.

Astronauts have started training on Orion spacecraft for preparation of an eventual trip of transporting spacefarers to the Red Planet. The test crew wore spacesuits to properly test the vehicle and to check their own ability of interacting with control systems while attired in full gear.

The Orion spacecraft has been designed to be the next space delivery system of the US space agency that can lift human payloads to orbit, and outside our planet. The vehicle is the keystone of NASA’s quest of transporting people to Mars.

A recently found exoplanet using Kilodegree Extremely Little Telescope (KELT) has three Suns in its sky. Though scientists know a number of planets with two Suns, the case of a planet with three bright stars in its sky is uncommon.

The newly discovered far away world, called KELT-4Ab, orbits a single star, and that star in turn is orbited by a close pair of stars.

A new study has revealed that the twin stars are sufficiently close to the planet to look as bright as the sky’s full moon is.

Besides coming up as an example of a solar system quite distinct from our planet, the odd arrangement could shed some light over the evolution of gas giants present close to their parent star, called ‘hot Jupiters’.

With the use of satellite imagery, archaeologists claim to have identified a site at Point Rosee in Newfoundland, Canada, that could probably be the first new Viking site discovered in North America in the past over five decades.

Archaeologists believe the newly discovered site has the potential to rewrite history, particularly the portion before the time of Christopher Columbus when Europeans explored North America.

Prior to this, it was in the 1960s that the only other Viking site in North America was found at L’Anse Aux Meadows on the northern tip of Newfoundland, about 300 miles from Point Rosee.

Researchers carefully examined a preserved fossil of an ‘almost spider’ to learn about the origin of spiders. The 305-million-year-old fossil was in Muséum National d'Histoire Naturelle in Paris. It was unearthed in the 1980s by a fossil hunter, Daniel Sotty, in the rock of Montceau-les-Mines.

Researchers were unable to analyze the fossil previously because a large part of it was buried in that ancient rock. Only the abdomen part of the fossil was visible.

Now, researchers have used modern technology to view the buried part of the fossil. They used high-resolution CT Scans and developed a three-dimensional model that demonstrates different traits of arachnid.

Until now, China has been the leading emitter of harmful greenhouse gases in the world, and emissions of CO2 in the country have been rising year after year. More than a year ago, US negotiators asked the government of China to pledge to curb greenhouse gas emissions in the country within a deadline.

Under an agreement, the US government also announced to reverse the growth of dangerous gases that cause global warming. China also pledged to limit the greenhouse gas emissions by 2030. The deadline is far off, but capital Beijing’s concession is a big step in efforts to effectively manage climate change, as per environmentalists.
