Nowadays, the Milky Way is a pretty quiet galaxy – but just a few million years ago its central black hole sent off huge flares of radiation.

Analysis of Saturn’s interior describes jet streams that continue deep below the surface and thick liquid that “flows like honey”.

Astronomers have detected a gravitational wave signal that appears to be caused by a black hole swallowing a neutron star. Aside from being an incredible cosmic cataclysm to witness, this detection is important for another reason: it may be the final point in the gravitational wave trifecta.

Human lives make it impossible to witness the full life cycles of stars, planets and galaxies. But sometimes, if we’re lucky, astronomers might be able to catch crucial moments playing out before their eyes. Now a team has done just that, watching as a red giant star goes through its death throes.

Engineers have recently focused on trying to emulate the structure of the brain with artificial synapses. Now, a team of researchers have made a new artificial synapse design that works using a light-based biotechnology technique called optogenetics.

A new species of human has been discovered in a cave in the Philippines. Named Homo luzonensis after the island of Luzon where it was found, the hominin appears to have lived over 50,000 years ago, painting a more complete picture of human evolution.

If you throw a particle at a wall, there’s a chance that it will suddenly appear on the other side. This is thanks to a phenomenon known as quantum tunneling, and now a team of physicists has measured just how long that process takes.

A study has found a huge new potential source of carbon emissions: reservoirs of gases trapped at the seafloor, which could be released as the oceans warm up. And the team suggests that these gases belched up from the deep thousands of years ago and put an end to the last ice age.

Advanced scientific instruments in orbit around the planet have given us the ability to track its stocks of groundwater resources, which researchers are now figuring out how to tap into to build more accurate predictions of drought and the risks that it brings months in advance.​

It’s long been thought that the Earth's inner core is a solid ball of iron, but direct evidence is hard to come by. Now, researchers from the Australian National University (ANU) have detected a type of seismic wave passing through the core that only propagates through solid objects.

A team of researchers has come up with plasma beam that can push space debris out of orbit. Mounted on a satellite, the two-way facing beam is produced by a bespoke ion thruster that uses its discharge to decelerate debris so it can burn up in the Earth's atmosphere.

Scientists have designed a new molecule they say could keep us ahead of the game when it come to drug-resistant malaria parasites, taking the best parts of a human protein to form a potent weapon that takes out the parasite before it gets any bright ideas.
