Radar systems used by civilian airports and military operations are inadvertently revealing our existence to potential advanced alien civilisations, new research shows. The study explored how hidden electromagnetic leakage might look to extraterrestrials up to 200 light-years from Earth, if they had state-of-the-art radio telescopes like our own. Theoretically, it also suggests this is how far we would be able to look to spot aliens who have evolved to use a similar level of technology. Preliminary results revealed at the Royal Astronomical Society’s National Astronomy Meeting 2025 in Durham show how worldwide aviation hubs such as Heathrow, Gatwick and New York’s JFK International Airport give off clues to our existence.
Researchers from RMIT University and CSIRO, Australia’s national science agency, have unveiled a method to significantly extend the lifetime of quantum batteries – 1,000 times longer than previous demonstrations.
A new FAU study shows astrocytes help neurons fire in sync, shaping brain rhythms key for attention, memory, and sleep – guiding how groups of neurons work together during high-focus or restful states.
Researchers at the College of Design and Engineerin at the National University of Singapore have discovered that human stem cells can be guided to become bone cells simply by squeezing through narrow spaces—without the need for chemical signals. The study, led by Assistant Professor Andrew Holle and published in Advanced Science, shows that physical confinement alone triggers genetic changes that push mesenchymal stem cells toward bone cell development. These findings could lead to new, low-cost methods for preparing stem cells for therapeutic use, particularly in bone repair. The research opens up promising possibilities for designing biomaterials and treatments that use mechanical forces to steer cell behaviour.The team is now exploring whether this confinement-based approach can also improve healing in injury models and be applied to more potent stem cell types used in regenerative medicine.
