Flicking the dimmer switch can help some indoor farmers curb one of their biggest challenges: rising electricity costs. Growing crops in stacked rows indoors under fixed-intensity artificial lights can produce more food per square foot using less land and water […]
The opposing fountains of plasma and particles spanning 23 million light-years are the longest pair of black hole jets ever seen. That’s far enough away to affect the evolution of the universe on a cosmic scale, astronomers report Sept. 18. […]
Quantum entanglement has made its way to the top. Scientists have measured the strange quantum phenomenon of entanglement in top quarks, the heaviest fundamental subatomic particles known. It is the first detection of entanglement between pairs of quarks – a […]
Dust pollution is known to contribute to asthma and heart and lung disease. But dust blowing from the Great Salt Lake in Utah can cause an additional unwanted shock. Metals in dust and sediments around the Great Salt Lake are […]
Bhavin Shastri still gets excited when he sees a laser pointer and has been fascinated by them since he was about 10 years old. “I was amazed that a beam of light could retain its brightness, concentrated in a small […]
