The 2020 Prime Minister’s Prizes for Science have recognised momentous achievements in astrophysics, sustainability innovation, epigenetics and primary and secondary teaching excellence.
Roger Penrose helped resurrect Einstein's general theory of relativity, and Reinhard Genzel and Andrea Ghez showed there was a black hole in the middle of our galaxy.
The 2020 Nobel Prize in physics was awarded to three scientists – an Englishman, an American and a German – for breakthroughs in understanding the most mysterious objects in the universe: black holes.
A new twist on an old experiment reveals several common-sense ideas about reality can't all be true.
Fluid mechanics can be applied to the transport of respiratory diseases such as COVID-19.
Twisted sound beams suggest an advanced civilisation may be able to harness immense amounts of power from a black hole.
Physicists can use bright, hot lasers to slow atoms down so much that they measure -459 degrees Fahrenheit.
There are two types of time travel: going back in time and going forward in time. And remarkably, people can feel time at different rates - but usually don't notice it.
Understanding sea ice loss requires expensive and difficult expeditions. Scientists have developed a new model that predicts the growth of small ponds on sea ice more efficiently.
Generating energy usually means wasted heat. Semiconductors let the electrons flow with zero waste – but so far scientists only know how to get them to work at ultra-low temperatures.
Practical work is essential for science education. But health measures compromise their traditional organization. Here are some game-changing solutions.
Researchers have made some of the most accurate clocks imaginable in recent years, but the trick is harnessing those clocks to electronics. Using lasers to tune microwaves bridges the gap.
A high-tech twist on an old idea – running on springs – could give human-powered movement its biggest boost in more than a century.
The movies make it seem like someday we'll be able to make people and objects grow really big or shrink really small. Whether this will be possible comes down to the smallest of things.
The term 'Big Bang' might make you think of a massive explosion. Put the thought out of your head. Rather than an explosion, it was the start of everything in the universe.
Mathematical maverick Stephen Wolfram's latest ambitious project calls on members of the public to help him find the rules that control the world.
Are molecules, chairs, genes and humans really just the sum of their physical parts? A team of philosophers are trying to find out.
A swarm of honeybees can provide valuable lessons about how a group of many individuals can work together to accomplish a task, even with no one in charge. Roboticists are taking notes.
There is a massive black hole in the center of the Milky Way galaxy. Measurements of star orbits near this black hole suggest that there may be a second companion black hole nearby.
