The solar system and beyond is awash in water
As NASA missions explore our solar system and search for new worlds, they are finding water in surprising places. Water is but one piece of our search for habitable planets and life beyond Earth, yet it links ...
Complex organic molecules discovered in infant star system
For the first time, astronomers have detected the presence of complex organic molecules, the building blocks of life, in a protoplanetary disk surrounding a young star, suggesting once again that the conditions ...
Astronomers solve decades-long mystery of the 'lonely old stars'
Many, perhaps most, stars in the Universe live their lives with companions by their sides – in so-called binary systems. Until recently, however, the ancient RR Lyrae stars appeared, for mysterious reasons, ...
Ants' intruder defense strategy could lead to better email spam filters, biologist finds
To kill spam, email filters might need to act a bit more like ants.
Scientists develop perfume which smells better the more you sweat
The first-ever perfume delivery system to ensure the more a person sweats, the better they will smell, has been developed by scientists at Queen's University Belfast.
Rice can 'borrow' stronger immunity from other plant species, study shows
Like most other plants, rice is well equipped with an effective immune system that enables it to detect and fend off disease-causing microbes. But that built-in immunity can be further boosted when the rice ...
The pale blue dot and other 'selfies' of Earth
Twenty-five years ago a set of images were taken that provided a unique view of Earth and helped highlight the fragility of our existence, and the importance of our stewardship.
'Teapot' nova begins to wane
A star, or nova, has appeared in the constellation of Sagittarius and, even though it is now waning, it is still bright enough to be visible in the sky over Perth through binoculars or a telescope.
