Five easy steps to start composting
According to the Environmental Protection Agency, about eight percent of all carbon emissions come from food waste, and about half of that comes from “the consumption stage,” which means waste from households and food services. This means that we can control about four percent of carbon Read More...
An X-ray explosion of a white dwarf star captured for the first time
Everything comes to an end, even stars! When these burning balls of hydrogen and helium use up all their fuel they shrink to white dwarfs. In some rare cases, these dead stars can flare back to life in an extremely hot explosion, producing a fireball of X-ray radiation. For the first time, Read More...
Algae powered a basic computer for over six months
Sometimes it can be pretty difficult to imagine our highly technological society coexisting with the natural world. We seem to live most of our lives entirely online, not just separated from nature, but also from physical space itself. However, scientists from the University of Cambridge have Read More...
Researchers have taught drones to survive any weather
Drones have provided humanity with many simple solutions and conveniences. These flying devices have helped prevent the spread of diseases, regenerate agricultural land and forests, track wildlife for conservation purposes, aided search and rescue missions, and much more.

Positive parasites, how deer and ruminant pests help the overall ecosystem
Some pests and critters annoy us, but everything in nature has its purpose and its place. Wolves are the villains of fairy tales, but they are in fact keystone predators that control the overpopulation of their prey. Beavers chew on powerline poles, but they also help preserve wetlands.

Breakthrough method that rescues lithium from wastewater
Electric vehicles are the future of transport. Electric vehicle sales increase year after year and, in 2019, accounted for 2.6 percent of global car sales. Electric vehicles are an essential change to be made for reducing the number of greenhouse gases and non-renewable resources used by humans, Read More...
A species of East African jumping spider targets recently fed mosquitoes
The enemy of my enemy is my friend, so the saying goes. As it turns out, this applies to humans and the natural world as well. Mosquitoes are the prime movers of malaria around the world, and scientists have worked hard to eliminate mosquitoes’ spread of this deadly disease. Yet, another species Read More...
Jumping robot leaps to new heights
A robot has been created that has smashed records to become the highest jumper to date, engineered or biological. The lightweight and aerodynamic machine can reach heights of around 100 feet (30 meters), being able to accelerate from 0 to 60 mph or nine meters per second. The study, published in Read More...
Orbex rocket prototype makes debut at Scottish Highlands spaceport
While humans are naturally earthbound creatures, we need space travel. Our society, as it is, needs the myriad functions and services our satellites provide, and so far, there’s only one way to get them up there. To that end, space scientists and engineers are constantly innovating ways to make Read More...
How do massive flocks of starlings fly in perfect unison?
Have you ever watched a flock of birds fly, turn, and dive in what seems like perfect unison? You might look at this and assume that a lead bird is determining the directions of the flock, or that they are collectively responding to small changes in the wind. All of those are good guesses, but Read More...
