Scientists achieve record-breaking data transmission speeds

Researchers have achieved record-breaking fibre-optic data transfer speeds of 402 terabits per second, roughly 1.6 million times faster than typical home broadband speeds. Scientists at Aston University in the UK achieved these new speeds by tapping into all the wavelength bands used in commercially available fibreoptic cables. Only one or two bands are used in most fibre-optic broadband connections.

T. rex could have been 70 per cent bigger

There's no denying that Tyrannosaurus rex was one of the biggest dinosaurs to ever walk the planet. But how big could this dinosaur get? In a new investigation, researchers attempted to answer that. Palaeontologists from the Canadian Museum of Nature in Ottawa estimated that the largest T. rex may have tipped the scales at a whopping 15,000 kilograms, making it heavier than an average school bus, which weighs about 11,000 kilograms.

Webb confirms the earliest known galaxy is erupting in stars

The James Webb Space Telescope has spotted the earliest galaxy ever seen, and its unusually bright light is coming from a bizarre frenzy of star formation. Named JADES-GS-z14-0, the galaxy formed at least 290 million years after the Big Bang and contains stars that have been bursting into life since an estimated 200 million years after our universe began.

Sapphires form inside volcanoes, not deep in the mantle

Brilliant-blue sapphires look like bits of sky brought down to Earth, but a new study finds these gemstones are from a different boundary: the one between the planet's crust and magma welling up from the mantle, Earth's middle layer. Sapphires have been thought to form in the mantle itself or in the lower sections of the crust.

Eating too much sugar may accelerate cellular ageing

A nutrient-rich diet with few added sugars may slow the rate of biological ageing in women. Scientists found that middle-aged women who ate more foods packed with vitamins, minerals and antioxidants had 'younger looking' cells than those who consumed less nutrient-rich diets.

The Space Force is launching lasers into orbit

The Space Force aims to better pinpoint the location of Earth's true centre using lasers on GPS satellites, slated to launch in 2025. A set of Laser Retroreflector Arrays, or LRAS, will be installed onto two GPS III satellites, SV9 and SV10, as part of NASA's Space Geodesy Program. The lasers are designed to make precise sub-centimetre measurements using a technique called Satellite Laser Ranging, which will allow researchers to more accurately determine Earth's centre.
