Water, it’s easy to take for granted when, with the flick of a wrist, you can get it pumped directly into your sinks, your showers, your toilets. The human body can survive for a substantial amount of time without food, that number varies depending on body composition and other factors, but it’s typically estimated anywhere from 8 to 21 days. That isn’t to say food is unimportant, just that on the hierarchy of needs, water is king. Depending on the circumstances, you may not even last a full day without it, so what do you do when you don’t have any?(more…)
Saving up excess solar and wind energy for times when the sun is down or the air is still requires a storage device. Batteries get the most attention as a promising solution although pumped hydroelectric storage is currently used most often. Now researchers are advancing another potential approach using sugar alcohols—an abundant waste product of the food industry—mixed with carbon nanotubes.
In the microscopic life that thrives around coral reefs, researchers have discovered an interplay between viruses and microbes that defies conventional wisdom. As the density of microbes rises in an ecosystem, the number of viruses infecting those microbes rises with it. It has generally been assumed that this growing population of viruses, in turn, kills more and more microbes, keeping the microbial population in check. It’s a model known as “kill-the-winner” — the winners being the blooming microbial cells and the killers being the viruses (mostly bacteria-killing viruses known as bacteriophages) that infect them.
Wikipedia reigns. It’s the world’s most popular online encyclopedia, the sixth most visited website in America, and a research source most U.S. students rely on. But Wikipedia entries on politically controversial scientific topics can be unreliable due to information sabotage.
How much does global warming really cost the world? Determining the Social Cost of Carbon helps put a actual dollar value on the climate damages per ton of CO2 released, and is used by — among others — policymakers to help determine the costs and benefits of climate policies. Remember, even on a global scale, the bottom line will always be profit. But now a group of economists and lawyers urge several improvements to the government’s Social Cost of Carbon figure that would impose a regular, transparent and peer-reviewed process to ensure the figure is reliable and well-supported by the latest facts.
The road to hell is paved with good intentions. This seems even more true when a new study came out that shows, when it comes to fixing deforestation and forest degradation, even good intentions can lead to bad outcomes. I hate to sound like a broken record when it comes to this whole “climate change” stuff, but it really needs to be addressed sometime…
Climate change talks, it’s like yelling at a wall and hoping it becomes a window. For over two decades, members of the United Nations have tried to forge an agreement to reduce global greenhouse gas emissions. Thankfully a new paper published offers a different approach to the problem using game theoretical modeling. (more…)
