Water on Mars Later Than Expected?

2 Nov

Water on Mars may have occurred later than scientists thought.

Mars hasn’t had an atmosphere in a really long time, which has prevented it from having liquid water on its surface, but new evidence from NASA indicates that liquid water may have existed later than expected. That evidence comes primarily from NASA’s Mars Reconnaissance Orbiter. Large basins seem to have formed millions of years after […]

A Quick Fall Vegetable Planting Primer

Fall garden crops

It’s pretty common for people to grow herbs and vegetables during the spring and summer. As the air gets crisp and frost sets in, most plants freeze and die. Many people don’t realize there are a variety of crops that can be planted in the fall. In fact, the cool weather even brings out the flavor […]

Using Candy and Drones to Save Black-footed Ferrets

15 Aug

A black-footed ferret,. This animal is endangered and getting more so thanks to a disease carried by its prey.

The black-footed ferret has been endangered for quite some time. They were actually listed as extinct in 1979, but a population was rediscovered in 1981, and as of 2011 there were about 1,000 of them in the wild. Since then, that number has dropped to about 300. That’s a 70 percent loss over five years, […]

Reducing Soil Runoff Without Impacting Crop Yield

14 Jul

soil runoff from crops

Agriculture and ecology form a tenuous balancing act. We need agriculture to grow food, but we also need to maintain ecosystems and not let farming ruin them. One significant problem is soil runoff near the beginning of the growing season. In the United States, for example, heavy spring rains erode soil, which finds its way […]

There are a lot of scientists working on ways to reduce humanity’s carbon emissions, and there are several systems in place to do exactly that. Carbon capture refers to removing CO2 from industrial waste, and there re a number of systems already set up to do that. Unfortunately, to date none of them are all […]

It’s a fact of life that people need electricity, but generating it is often harmful to the environment. Moving forward, we need to find more ways to generate power that have less of an impact on the world around us. That’s where hydropower comes in. One form of green energy, hydropower uses rivers and streams to […]

The Ozone Hole is Finally Healing

5 Jul

Earth's ozone hole

Remember the hole in the ozone layer? It was discovered back in the 1980s, caused by Chlorofluorocarbons (CFCs) in all kinds of consumer products. Back in 1987, a number of governments ratified the Montreal Protocol in order to help combat the problem. Since then, we’ve done a lot to phase out CFCs, and it’s finally starting […]

By 2025 Half Our Power Should Be Emissions-Free

The United States, Mexico, and Canada have signed a continent-spanning agreement to increase production of emissions-free electricity, improving the number to 50% across the three nations. Currently, about 37% of the continent’s electricity is generated with emissions-free means, such as hydropower, wind power, or solar power. Such generation doesn’t create carbon emissions, which are a […]

Climate Change Is Messing With Plant and Animal Calendars

29 Jun

Thanks to the longstanding tradition in the United Kingdom of people observing and recording natural events like flowering, bird migration, or nesting habits, researchers have been able to determine that changing weather patterns are impacting the “calendars” that plants and animals keep. Temperature change tends to have a bigger impact on nature’s cycles than precipitation, […]

The City Bee and the Country Bee

As humans have known for millennia, and as many authors have reminded us, city life is hard–but it has some advantages. The same turns out to be true for bees, who suffer from a higher rate of parasites in urban environments, but pollinate more plants than they do in agricultural areas. First off, the parasites in […]
