Frogs are screaming – we just can’t hear them, scientists in Brazil discover | Science & Tech News
admin
Some frogs scream at an ear-splitting volume for other animals but its frequency is inaudible to humans, scientists have discovered. While out in the Amazonian jungle studying frogs, researchers in Brazil noticed something strange. Small leaf litter frogs were arching their backs, throwing back their heads and opening their mouths wide. They looked like they…

Astrocomb breakthrough could help discover Earth-like planets | Science & Tech News
admin
New Earth-like planets could soon be discovered after scientists made a technological breakthrough. Physicists have developed an astrocomb that can analyse the blue-green light emitted by stars. Astrocombs can detect tiny variations in a star’s light created by orbiting exoplanets (those beyond our own solar system) – potentially revealing one similar to Earth. They have…

Scientists discover tiny fish can make sounds as loud as a pneumatic drill | Science & Tech News
admin
Scientists have discovered one of the world’s smallest fish is capable of making sounds registering more than 140 decibels – which is louder than a pneumatic drill. The translucent Danionella cerebrum is just 12mm-long and has the smallest known brain of any vertebrae. The sound was first noticed by scientists studying the species in Berlin,…

Scientists discover dozens of possible planets that could be cool enough for life | Science & Tech News
admin
Astronomers have discovered 85 possible planets outside our solar system with temperatures that could be cool enough for life. These exoplanet candidates are similar in size to Jupiter, Saturn and Neptune, and were discovered using data from NASA‘s Transitioning Exoplanet Survey Satellite (TESS). TESS enables scientists to observe dips in the brightness of stars, known…

Astronomers produce significant star cluster image – and discover mysterious radio signal | Science & Tech News
admin
Astronomers have created the most sensitive radio image ever of an ancient star cluster – and discovered a radio signal at the centre of it. The image, which can be seen above, is of the second brightest globular cluster in the night sky, known as 47 Tucanae. Star clusters are an ancient relic of the…

Scientists discover oldest ever black hole and say it could explain universe’s mysteries | Science & Tech News
admin
Astronomers say they have discovered the oldest black hole yet. It was formed 470 million years after the Big Bang and was detected in X-rays, using NASA telescopes. There is “strong evidence” it was born “massive” – and is believed to weigh between 10% and 100% the mass of all the stars in its galaxy.…

NASA launches mission to Psyche metal asteroid to discover how life on Earth formed | Science & Tech News
admin
NASA has launched a mission to a rare asteroid covered in metal that is two billion miles (3.6bn km) and six years’ travel time away from Earth. Scientists hope exploring the Psyche asteroid will help them understand more about how Earth formed and what makes it habitable. Lead scientist Lindy Elkins-Tanton, of Arizona State University,…
