Honey bee colonies managed using organic methods were as healthy and productive as those managed in conventional systems, while avoiding the use of synthetic pesticides to control pests and pathogens inside the hive, according to newly published research led by Penn State entomologists.

Ol' RHESSI A decades-old NASA satellite is about to plummet back down to Earth — and there's a non-zero chance it could hit somebody on the surface below. Nearly 21 years after it was launched in 2002, NASA's retired Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) spacecraft — a satellite that observed solar flares and coronal mass ejections — is expected to reenter the Earth's atmo

Formula 1 legend Michael Schumacher hasn't made a public appearance in almost a decade, since he suffered a near-fatal brain injury while skiing back in December 2013. But that hasn't stopped German tabloid rag Die Aktuelle from advertising "the first interview" — a "world sensation!" — with Schumacher since his accident, boldly plastering his face on a recent issue of the magazine. "No meagre, n

"Every once in a while a book lands on your desk that changes the way you perceive the world you live in, a book that fundamentally challenges your understanding of human history." So began the blurb that came with this book. Aha! I thought. The usual advertising hyperbole, a gross exaggeration.

Many have observed that sometimes when given a toy as a present, children play with the box the toy came in, or even the gift wrapping.

Corporal punishment (e.g., spanking) is allowed in Canada according to Section 43 of the Criminal Code of Canada. Some Canadians are not aware of this and are surprised to learn that such a law exists, whereas others want to hold onto this archaic act.

Lunar exploration is undergoing a renaissance. Dozens of missions, organized by multiple space agencies—and increasingly by commercial companies—are set to visit the moon by the end of this decade. Most of these will involve small robotic spacecraft, but NASA's ambitious Artemis program, aims to return humans to the lunar surface by the middle of the decade.

Fatal encounters with police are on the rise in Canada. The number of civilians dying in incidents with police when force is used has steadily increased since 2000. This is leaving families and communities with little support or recourse for accountability.

Unlike large-acreage government irrigation schemes, small-scale irrigation is typically farmer led. Farmers decide what technologies to use to extract water, be it manual lifting or solar water pumps. They also choose the mode of irrigation, whether by buckets or drip kits. Farmers purchase, run and maintain the operation themselves on their own farms or as part of small groups of farmers.
