On a Thursday afternoon in June, a 17-foot-tall rocket motor—looking like something a dedicated amateur might fire off—stood fire-side-up on the salty desert of Promontory, Utah. Over the loudspeakers, an announcer counted down. And with the command to fire, quad cones of flame flew from the four inverted nozzles and grew toward the sky. As the…

Clouds perform an important function in cooling the planet as they reflect solar energy back into space. Yet clouds also intensify warming by trapping the planet’s heat and radiating it back to earth. As fossil fuel emissions continue to warm the planet, how will this dual role played by clouds change, and will clouds ultimately exacerbate…

It’s not a bird or a plane but it might be a solar storm. We like to think of astronauts as our super heroes, but the reality is astronauts are not built like Superman who gains strength from the sun. In fact, much of the energy radiating from the sun is harmful to us mere…

Research conducted in a collaboration between Drs. Dun Mao, a researcher in Dr. Bruce McNaughton’s lab at the Canadian Centre for Behavioural Neuroscience at the University of Lethbridge, and Steffen Kandler, a researcher in Professor Vincent Bonin’s lab at Neuro-Electronics Research Flanders (NERF) in Belgium, has found neural activity patterns that may assist with spatial…

Bumblebees are less able to start colonies when exposed to a common neonicotinoid pesticide, according to a new University of Guelph study.Prof. Nigel Raine has discovered that exposure to thiamethoxam reduces the chances of a bumblebee queen starting a new colony by more than one-quarter.

Even after so many years of doing field work, sometimes you are still left amazed. Because every now and then the stars all align, and everything works out exactly as you hoped it would. Today was one of those times, because we found that needle in the haystack.

Amphibians can evolve increased tolerance to pesticides, but the adaptation can make them more susceptible to parasites, according to a team that includes researchers at Rensselaer Polytechnic Institute. The research, led by Binghamton University, showed that wood frogs that evolved increased tolerance to pesticides showed greater susceptibility to a dangerous virus, although they also demonstrated reduced…

Last week, researchers at Sandia National Laboratories flew a tethered balloon and an unmanned aerial system, colloquially known as a drone, together for the first time to get Arctic atmospheric temperatures with better location control than ever before. In addition to providing more precise data for weather and climate models, being able to effectively operate UASs…

Battery researchers agree that one of the most promising possibilities for future battery technology is the lithium-air (or lithium-oxygen) battery, which could provide three times as much power for a given weight as today’s leading technology, lithium-ion batteries. But tests of various approaches to creating such batteries have produced conflicting and confusing results, as well…

University of Sydney researchers have found a solution for one of the biggest stumbling blocks preventing zinc-air batteries from overtaking conventional lithium-ion batteries as the power source of choice in electronic devices.Zinc-air batteries are batteries powered by zinc metal and oxygen from the air. Due to the global abundance of zinc metal, these batteries are much cheaper to…
