Dairy farmers in the Northeast can improve water quality and boost the profitability of their operations by changing the timing and method of applying manure to their fields in the fall, along with planting rye as a cover crop between corn crops — or by double-cropping rye and corn, according to Penn State researchers.
Prime Minister Narendra Modi announced last week that the Mission Shakti test had successfully destroyed a satellite in low-Earth orbit. Now, NASA is expressing concern that the test could have placed the International Space Station at risk. The post ISS at Increased Risk of Impact After Indian Anti-Satellite Weapon Test appeared first on ExtremeTech .
Methicillin-resistant Staphylococcus aureus (MRSA), a bacterium that causes infection in various parts of the body, is often called a 'superbug' thanks to its ability to dodge many common antibiotics. Rather than rolling the dice with a multi-drug combination or wasting precious time trying to determine which medicine to prescribe, doctors could soon use a new method for disarming the superbugs: l
Dogs that receive omega-3 fatty acid supplements or have hypothyroidism may be less likely to develop T-zone lymphoma (TZL). Those are two findings from Morris Animal Foundation-funded researchers at Colorado State University, who studied associations of environment and health history of the disease among golden retrievers. They published their results in the Journal of Veterinary Internal Medicin
Multiple lines of evidence suggest the gas occasionally surges into the Red Planet's atmosphere. Could it be a sign of a subsurface biosphere? — Read more on ScientificAmerican.com
Walmart will now allow its shoppers to order their groceries by voice through Google's smart home assistant, its latest attempt to challenge Amazon's growing dominance.
Death From Above Earlier this year, Russian weapons manufacturer Almaz-Antey filed a patent for a new drone that was little more than a shotgun with wings. When Futurism first reported on the drone , details were scarce. But now, video footage of flight tests has surfaced showing the drone — which looks like a murderous model plane — in action. Balancing Act The drone carries a 12-caliber Vepr-1
Escape-Proof Prison If any of the inmates at Yancheng prison are considering an escape attempt, they'd better do it soon. The Chinese prison is currently wrapping up months of construction on a new "smart" surveillance system designed to monitor prisoners at every moment, including while they are in their cells. According to officials , this digital panopticon will make prison breaks virtually im
