Hummingbirds can perceive colours that the human eye cannot, thanks to the addition of an extra cone in the hummingbird’s eye that we don’t possess, new research reveals. The findings, demonstrated in experiments with wild broad-tailed hummingbirds (Selasphorus platycercus) in Colorado, suggest that the ability to discriminate non-spectral colours (including ultraviolet wavelengths) could play a

For the first time, astronomers were able to watch the entire process of a neutron star absorbing material and eventually unleashing a powerful blast of X-rays. Scientists have long wondered why neutron stars create these violent outbursts.   This time around, it took 15 scientists from five institutes using seven observatories in order to gather the complete

When Canadian astronomer Robert Weryk discovered ‘Oumuamua passing through our Solar System with the Pan-STARRS telescope, in October 2017, it caused quite a stir. It was the first interstellar object we’d ever seen coming through our neighbourhood. The excitement led to speculation: what could it be?   There was lots of fun conjecture on its origins. Was it

Scientists have developed a human embryo “blueprint” using human stem cells, in a breakthrough that could provide vital insight into the early stages of infant development, new research showed Thursday.   Teams from the University of Cambridge and the Netherlands-based Hubrecht Institute said their model will allow them to observe never-before-seen processes underlying the formation

Yet again, scientists have validated a major component of Einstein’s theory of general relativity. Specifically, a trio of two white dwarf stars and a collapsed neutron star demonstrated the concept of freefall, according to research published this month in the journal Astronomy and Astrophysics.   That’s the idea, famously illustrated by Galileo’s Leaning Tower of Pisa thought experiment, that

With the Black Lives Matter movement dominating headlines in the last week, systemic racial inequality in academia has also been brought to the forefront, with the hashtag #BlackintheIvory.   Across social media, Black academics and educators are sharing countless stories on how they have been subjected to systemic racism, and blatant discrimination from White colleagues.

The northern segment of the Great Wall of China was built not to block invading armies but rather to monitor civilian movement, an Israeli archaeologist said Tuesday. When researchers fully mapped the Great Wall’s 740-kilometre (460-mile) Northern Line for the first time, their findings challenged previous assumptions.   “Prior to our research, most people thought

The famous cat-in-a-box thought experiment by Austrian physicist Erwin Schrödinger is an illustration of one of the defining characteristics of quantum mechanics – the unpredictable behaviour of particles at the quantum level.   It makes working with quantum systems incredibly difficult; but what if we could make quantum predictions? A team of physicists believes it’s
