The history of our Universe is written in the skies. Radio astronomers can detect ancient signals from the dawn of time as well as light from our nearest neighbours. Separating out these layers of time and space allows them to reconstruct the evolution of the Universe. This film reveals how thirteen billion years of history […]

Brachytherapy has a robust track record as a treatment for prostate cancer. The technique involves positioning radioactive materials inside the prostate to kill the tumour.

Though humans don’t experience it in their daily lives, gravity and movement can change how time elapses. Ultra-precise atomic clocks are now able to measure these tiny changes, known as time dilation. It’s a technological advance that could revolutionize our understanding of time.

Nothing in the Universe is static. In the milky way, billions of stars orbit the galactic center. Some, like our sun, are pretty consistent, keeping a distance of around 30,000 light years from the galactic center, completing an orbit every 230 million years. This dance is not an orderly ballet – more like a skating […]

The naked mole-rat may not be the most attractive rodent on the block, but it’s still a social butterfly. These hairless, mostly blind and deaf animals live in colonies of up to 300 individuals, which communicate with high-pitched squeaks. Now, researchers have discovered that, like humans and many birds, mole-rat communities have their own dialect, […]

Si no tiene una sustancia activa ¿por qué funcionan los placebos? ¿Por qué nos sentimos mejor cuando vamos con el homeópata o nos hacen una limpia?

After a seven-month-long journey, NASA’s Perseverance Rover successfully touched down on the Red Planet on Feb. 18, 2021. Mission controllers at NASA’s Jet Propulsion Laboratory in Southern California celebrate landing NASA’s fifth — and most ambitious — rover on Mars. A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs […]

Animations for media and public use. NASA’s Mars Helicopter Ingenuity will be the first aircraft to fly in a controlled way on another planet. As its own separate mission, the helicopter will hitch a ride to Mars attached to the belly of NASA’s Perseverance rover (part of the Mars 2020 mission). This animation reel simulates […]

After nearly 300 million miles (470 million km), NASA’s Perseverance rover completes its journey to Mars on Feb. 18, 2021. But, to reach the surface of the Red Planet, it has to survive the harrowing final phase known as Entry, Descent, and Landing.

For years, scientists have wanted to create flying robotic vehicles the size of insects. The tricky bit has been building something that can produce enough thrust while still being light enough to fly, without being tethered to an external power source. Now, a group of researchers have hit on a new design. At half the […]

Hallada en 1931 en la cueva de Marsoulas, en los Pirineos franceses a 250 km del mar, esta antigua caracola llamó entonces la atención por su gran tamaño. Lejos de servir de copa para beber durante el Paleolítico superior, como se creía, una nueva investigación indica que pudo ser en realidad un instrumento único de […]
