Hunting for missing dark matter or gravitational waves involves incredibly precise measurements. Scientists are constantly developing new measurement techniques to try and find new sources of data and test theories. Whether it be staring at the space between Andromeda and the Milky Way to find primordial black holes, to looking in the remnants of a white dwarf using spectroscopy. Plus ways to make the newer generation of gravitational wave detectors more accurate by listening to quantum noise.

Cracks in metal can ultimately lead to fatigue failure, but is there a way to unwind the damage? Fatigue failure is a serious problem for everything from bridges to phones so finding a way to tackle it is important. One microcrack can turn into another as a metal fatigues, but what if the cracks co…
When whales and humans interact the results can be confusing and messy for both sides. Whether it be noisy boat propellers, or orcas on a collision course, humans and whales don't always get on. How can we monitor and track how whales respond to humans. The best ways of monitoring animals is often …
How long do you really have to wait after a concussion? Athletes are always keen to get back in the game after a head knock, but how long do they really need to wait? When trying to assess and track a concussion getting hard data is difficult. Using special headbands and measuring the pulse of the …
Antibiotic resistance is a global challenge, but the solution may come from the natural predator of bacteria. Bacterial infections can be nasty, but you can engineer a phage to help better identify and treat them. Knowing exactly which bacteria is causing problems can help doctors target treatment …
Getting an accurate picture of someone's health or vital signs is essential in medicine, but hard to physically do without wires. Invasive health monitoring systems can't provide insights into 'everyday' scenarios. Trying to assess someone's posture, gait and rehabilitation is hard if they're wired…
