The experiments prepared by 750 schoolgirls from India failed on their first try in 2022. But later, it transformed into a space education activity that has a satellite made by them orbiting the planet near the ISS. The information was released by ISRO, the Indian government’s space agency.Under the AzaadiSAT project, 75 schools across the…
Burning soil and peat drove most emissions in Canada’s record 2023 wildfire season, study finds Underground stores of rich soil and thick peat were the main fuel behind the record emissions created during Canada’s 2023 wildfire season. Rather than standing trees and leaves, carbon locked beneath the forest floor accounted for 76 per cent of…

The first place people consider when thinking about the source of the oxygen that humans breathe is usually the big rainforest areas like the Amazon. Although forests play a very important role in storing carbon and conserving biodiversity and climate, the oceans provide a greater share of the oxygen in the atmosphere than forests. Almost…
For many people, Lewis Howard Latimer is remembered for his later work on electric lighting and his association with Thomas Edison. Yet years before he became involved in the electrical industry, he helped solve a far more ordinary problem that affected railway passengers every day. Travelling by train in the nineteenth century was becoming increasingly…
Mosquitoes are among the world’s deadliest animals, spreading diseases such as malaria, dengue, Zika and yellow fever that affect hundreds of millions of people every year. While traditional mosquito control relies on insecticides, bed nets and habitat management, researchers are now exploring a high-tech alternative. An experimental autonomous drone uses ultrasonic phased-array sonar, artificial intelligence…
However, the construction industry accounts for a great part of the global CO₂ footprint due to massive emissions of carbon dioxide while producing cement and concrete. Although some success has been achieved by architects and engineers in the creation of alternatives, there is still no such type of sustainable building material that would not only…
Deep inside Brazil’s Atlantic Forest, far from crowded towns and city streets, scientists found a surprising pattern in the insects they were studying. Mosquitoes living in protected forest areas appeared to have been feeding on humans more often than expected, despite being surrounded by natural habitat. The discovery has raised questions about how environmental change…
Two people can spend years inside the same demanding, unglamorous work and come away describing it completely differently. One calls it a job, something endured for the sake of what it eventually produces. The other calls it beautiful, and means it literally, even in the middle of the most exhausting stretches of it. Marie Curie,…
The sounds of singing birds drifting through a leafy forest may do more than create a peaceful atmosphere; they could measurably improve mental health. A new study has found that spending just 10 minutes in a restored urban forest while listening to birdsong reduced people’s stress, increased positive emotions and made them feel more mentally…
