How Radical Enviros Made Africa’s Locust Problem Worse

Two weeks ago a Boeing 737 on final approach to Dire Dawa, Ethiopia, flew into a massive cloud of locusts swarming above the airport. The insects were sucked into the plane’s engines and splattered across the windshield, blinding the pilots to the runway ahead….

Blue-emitting diode demonstrates limitations and promise of perovskite semiconductors

(University of California – Berkeley) Halide perovskites have garnered attention because they’re highly efficient at capturing energy in solar cells and efficient emitters in diodes. But researchers failed at making perovskite LEDs that emit blue light. UC Berkeley chemists succeeeded, but X-ray studies of the LED’s structure show that it’s very sensitive to temperature, humidity and chemical environment. Hence environmental and chemical control is essential for stable operation. But these properties also allow for potentially broader use, such as sensors.

How old are they? Some non-photosynthetic orchids consist of dead wood

(Kobe University) A research team led by Kobe University’s Associate Professor SUETSUGU Kenji (of the Graduate School of Science’s Department of Biology) has investigated the carbon age in some non-photosynthetic mycoheterotrophic plants. Using the radiocarbon emitted from atmospheric nuclear bomb tests carried out in the 1950s and 1960s as a tracer, they revealed that some mycoheterotrophic orchids are relying on 14C-enriched bomb carbon from dead wood via saprotrophic fungi.

These Are the Causes of Global Warming – Green Matters

With 2019 going on record as the second-hottest year to date, global warming continues to be a real threat to our environment, livelihood, and the world as we know it. Six of the hottest years so far in recorded history…

Opinon: We want to end global warming but we idle our engines. Stop it! – The Mercury News

Many Californians are understandably concerned about global warming, the environment and the future of the planet. So what about our favorite pastime of idling car engines on the side of the road while checking e-mail, texting, staring into space, eating…

Scientists turn frog cells into living machines

[embedded content] Scientists have taken a bold leap into the future with robots built from frog parts. New research published this week in PNAS from Tufts University and the University of Vermont describes how frog stem cells can create a…
