Tropical Cyclones Collide!

In April 2021, tropical cyclones Seroja and Odette merged with one another in the Indian Ocean, just north-west of Australia. The Australian Bureau of Meteorology (BOM) described this merger as rare. Two scientists from the University of Oldenburg, Germany have studied this phenomenon in detail to understand how these newer, more unpredictable weather patterns, driven by climate changes, are impacting us.

Greenland’s Ice Sheet is Melting Faster Than Ever!

Greenland’s Ice Sheet is Melting Faster Than Ever!

Scientists working at the National Aeronautics and Space Administration (NASA), and the European Space Agency (ESA), conducted a series of aerial surveys over Greenland using two drones, the CryoSat-2 and the ICEsat-2. Greenland is the world’s largest island and 80% of its surface is covered by a single ice sheet or glacier with an average thickness of 1.67 kilometers. The aim of the survey was to monitor the thickness of this ice sheet over time. The results were worse than expected and show that the ice sheet is melting faster than ever.

Concrete Mixed with Old Fabric Creates a Better, Stronger Alternative

Concrete Mixed with Old Fabric Creates a Better, Stronger Alternative

In Australia, over 200,000 tons of clothing make their way to landfill every year! This number is astonishing, so the Royal Melbourne Institute of Technology (RMIT) decided to explore ways to repurpose some of this discarded clothing. Their research team has created a new type of concrete, more durable and hardier, using an unexpected component – old fabric. They mixed regular concrete with discarded fabric fibers and the result was a sturdier, stronger, and crack-resistant cement.

“Forever Chemicals” are Slowly Killing Freshwater Turtles

The Commonwealth Scientific Industrial and Research Organisation (CSIRO) has partnered with the Queensland Department of the Environment, Tourism, Science, and Innovation (DETSI) to study the impact of ‘forever chemicals’ on freshwater turtles. This is still an ongoing study; however, some of the early results are heartbreaking. It is not only the adult turtles that are vulnerable, but their hatchlings are being affected too.

Now it’s Truly a Fruit – Scientists Create Genetically Modified Sweeter Tomatoes!

Now it’s Truly a Fruit – Scientists Create Genetically Modified Sweeter Tomatoes!

Have you ever bitten into a big, red, juicy tomato and found that it was sour or watery on the inside? Scientists are trying to solve this problem by creating tomatoes that are higher in their sugar content without losing size. The tomato, which literally means pulpy berry, has been cultivated for the last 7,000 years. Researchers have discovered that, through the years, farmers have preferred tomatoes that ripen together and are visually appealing, over taste. To support the production boom that took place after World War II, seed companies changed their tomatoes to increase their yield and to make them more pest resistant.
