Two new dinosaur species discovered in China
A great number of dinosaur fossils have been discovered in China's northwest region in recent years and a new study confirms that the region has yielded two fossils of previously unknown dinosaurs the size of blue whales. The two new species, which are named Silutitan sinensis and Hamititan Read More...
This ultra light microbattery uses its own casing to store more energy
Improving the way current batteries store and deliver power is key to enabling faster charging and enhanced performance of electronic devices. However, the structural composition of most batteries today prevents the rapid transport of electrons and ions, limiting power density. Scientists have Read More...
Why public transportation systems are the perfect microgrid candidates
Fleet vehicles, including public transportation vehicles, are critical for embracing a transition to fossil fuel-free transportation, but committing to transitioning a whole city bus or train system to electric power is no easy feat. Fortunately, microgrids could play a critical role in this Read More...
Indigenous communities combat deforestation with smartphones
As the recent Intergovernmental Panel on Climate Change (IPCC) report made clear, we must act quickly to restore and protect what’s left of the world’s biodiversity while reducing and capturing carbon emissions from the atmosphere. The Amazon rainforest is a vast area of dense forests that Read More...
How cargo delivery bikes can curb road congestion and pollution in cities
Online shopping has seen a surge during COVID-19. This, of course, went hand in hand with an increased number of double-parked delivery vans blocking traffic in urban areas and emitting greenhouse gases into the atmosphere. A new report proposes that logistics companies start parting ways with Read More...
Another reason to get swimming this summer: It’s good for our brains!
It’s summertime and the weather is hot (in the Northern hemisphere at least), which means you’re probably itching to cool off in some water. In addition to saving you from the summer heat, it turns out that swimming actually has cognitive benefits as well. Let’s dive deeper into its brain Read More...
Barnacle-inspired glue can stop bleeding in less than 30 seconds
Currently, most bleedings during surgery or traumatic injury are stopped with hemostatic agents, materials that induce the blood to clot. These, however, can take a few minutes to work and don’t always do their job properly if there’s too much blood, which can make it difficult to get adhesives Read More...
Sustainable wood-based batteries could power the future of e-travel
While the world is steadily moving towards a predominantly battery-powered future, conventional batteries still pose a few major sustainability- and efficiency-related challenges. Seeking to come up with a solution, Finnish designer Stora Enso is working on a wood-based material that could produce Read More...
Scientists observe supernova explosion in unprecedented detail
In a world-first, astronomers have recorded the earliest moments of a supernova — the powerful explosion of a massive star — in unprecedented detail. The observation is a celebratory moment in the world of astronomy that could help improve our knowledge about what happens to stars the moment Read More...
German farm demonstrates dual benefits of agrivoltaic systems
Agrivoltaic systems make for the perfect symbiotic relationships on farms. They combine solar panels and farming to provide localized renewable energy while helping shade crops to reduce water usage. The plants also work to cool the solar panels for increased productivity. At one farm in Germany, Read More...
