Asteroid could end life on earth after 10 million years, warn scientists

A new study led by Professor Gemma Harvey from Queen Mary University of London has revealed how hundreds of species shape the landscapes we depend on, from termite mounds visible from space to beavers creating wetlands and hippos carving drainage systems.

The majority of known asteroids orbit inside the main asteroid belt, which is positioned between Mars and Jupiter at an average distance of around 250 million km from Earth. Since the discovery of the first asteroid in 1801, about 750.000 asteroids have been identified, primarily in the last decade thanks to several optical surveys that examine the sky on clear nights.

A newly developed timeline of early animal fossils suggests a relationship between sea level fluctuations, variations in marine oxygen, and the appearance of the earliest ancestors of present-day animals.

A total solar eclipse is slated to take place today when the Moon will pass between the Sun and Earth, completely blocking out the Sun's light.

Researchers use historic hot springs to investigate the beginnings of life on Earth.

As if having a hereditary blood illness that might be crippling at birth wasn't enough, research indicates that almost two-thirds of infants with sickle cell disease are born to moms who reside in underprivileged neighbourhoods.

Carbon, the main component of life on Earth, is continuously moving from living things down into the crust and back up into the atmosphere.

Wearable gadgets that vibrate to provide orientation cues, however, have been identified by scientists to significantly improve the efficacy of this training, making spaceflight marginally safer.

The sky is no longer the limit - but flying is risky. We lose many of the clues we need to orient ourselves when we leave the Earth's surface, and this spatial disorientation can be fatal. Astronauts typically require extensive training to protect themselves against it. However, scientists have discovered that wearable devices that vibrate to provide orientation cues may considerably improve the efficacy of this training, making spaceflight slightly safer.

A recent double-blind, randomised controlled experiment discovered that an educational and social support intervention for caretakers reduced elder abuse among older people with chronic conditions, including dementia.
