Who wouldn't want to travel in time, glimpsing the dinosaurs or peeking at humans 2,000 years from now? Now physicists have designed a time machine that seems deceptively simple.
Academic rigour, journalistic flair

What colours we see depends not just on how things are in the world around us, but also on what happens in our eyes and our brains.
Alongside their famous dangers, radioactive materials have many beneficial uses. With as many more predicted as have already been discovered, nuclear physicists are searching for more isotopes.
By improving trainee physics teachers' content knowledge and skills, we make them better.
Perhaps precisely because they are so elusive, Fast Radio Bursts have received a lot of attention in the years since their discovery.
The energy needed to pull magnets apart comes from you, and you get it from the food you eat. And the plants or animals you eat get their energy from other plants and animals, or from the Sun. All energy comes from somewhere.
The award of a Nobel Prize in physics to Donna Strickland is an opportunity to build support for women in science, says one female physics professor.
Donna Strickland is the first woman in 55 years to be awarded the Nobel Prize in Physics. Let's hope the next such award to a woman won't take so long.
Using lasers to trap and move particles changed the way we're able to study microscopic life.
The way science is currently taught in southern African countries ignores the fact that the whole environment is a laboratory for learning.
The new physics syllabus for year 11 and 12 students in NSW contains no mention of specific women who have contributed to the field, nor their work.
Astronomers are voting to rename one of the laws of physics. The voting may have far-reaching effects leading to renaming of other laws and giving 'forgotten' scientists due credit.
It's not just Earth: everything in the universe has it's own pull because of gravity – even you. Here's how it works.
Machine learning is changing the world in ways that we are just beginning to appreciate. But could it change the way we do science and the reasons why we do science?
If you fall one storey, dust yourself off – you'll be fine. If you fall seven storeys: sorry, but you've probably got about 2 seconds to prepare to meet your maker.
If the insect wants to stay right in front of your nose, it must fly forwards just a little bit when the car is speeding up. But when the car is at constant speed, it only needs to hover.
To answer this tricky question, we have to look back in time to when the Earth was born, 4.5 billion years ago.
In 1954, three scientists observed a paradox to which they gave their name: the Fermi-Pasta-Ulam recurrence. Now, fibre optics are on the way to finally providing an explanation.
Listen up. Today we're hearing all about why your ears pop when you go up, up, up and away.

Today on Trust me, I'm An Expert, we're explaining the tricky topics: what is quantum mechanics? What does the research say about lone actor terrorism? And why do people like pimple popping videos?
