The honeybee (Apis mellifera) has joined the ranks of dolphins, parrots, and primates, in demonstrating the ability to understand the concept of zero numerosity. The study appears in the journal Science. A honeybee (Apis mellifera). Image credit: Vijaya Narasimha. While intuitive to modern humans, the full understanding of zero is …

A team of planetary researchers at the University of Colorado at Boulder has offered up a new theory for the existence of strange trans-Neptunian objects — called ‘detached objects’ — such as the minor planet Sedna. An artist’s concept of the minor planet Sedna; the Sun appears as an extremely …

    (CNN)– Wished to see 16 daybreaks in one day? Drift in absolutely no gravity? Be one of the few to have gazed upon our home world from space? In just 4 years’ time, and for an astronomical $9.5 million dollars, it’s declared you can. What’s being billed as …

NASA launched the New Horizons probe to visit Pluto, and it became the first-ever spacecraft to do that several years ago. With that phase of the mission complete, what was a deep space robot to do? NASA decided to keep New Horizons going and take a look at objects in …

Not that you might inform by taking a look at it, but the glass of water sitting on your desk consists of two various kinds of water molecule rotating in discreetly different ways. A current experiment handled to separate them, finding one is far better at responding than the other. …

In July 2012, ATLAS (A Toroidal LHC ApparatuS) and CMS (Compact-Muon-Solenoid) experiments at CERN’s Large Hadron Collider jointly announced the discovery of the Higgs boson. The discovery confirmed the existence of the last missing elementary particle of the Standard Model, five decades after it was predicted theoretically. New results from …

NASA’s Mars rover Curiosity has detected organic molecules in 3-billion-year-old sedimentary rocks at the base of the Murray formation at Pahrump Hills, Gale crater, as well as seasonal variations in the levels of methane in the Martian atmosphere. Mosaic of the Valles Marineris hemisphere of Mars projected into point perspective, …

Finding planets orbiting distant stars is only the first stage in the search for alien life. Most of the exoplanets detected by astronomers currently are large gas giants, and the smaller ones might be too hot, cold, or radioactive. We need to understand the environment around the host stars to …

The Mars of today is a barren and inhospitable place for living things, but scientists think it may have been very different in the past. One of NASA’s aims with the Curiosity Rover is to search for signs of ancient life on the red planet. The rover has returned a …
