Compared to the control, the number of flower landings decreased by 89 percent for diesel, 83 percent for ozone, and 90 percent for both.“Our results suggest that air pollution is another potential stressor to add to the growing pressures on pollinators”—a list that already includes disease, habitat loss , and pesticides, says lead author James Ryalls, a research fellow studying the chemical ecology of plant-insect interactions.
The scientists noticed that when the pusher fluid, which contains long-chain polymers, was pumped into the ground above a certain rate, it seemed to unexpectedly become much more viscous, or sticky, an effect later found in many similar systems.
Flood flows on the Buller River this month were the largest of any river in Aotearoa New Zealand in almost 100 years, NIWA measurements show.Meanwhile, a NIWA monitoring station on the Buller River at Te Kuha, about 10km upstream, was continuously recording water levels throughout the flood.
Energy from the LEDs heats up the Mylar’s specially-coated underbelly, energizing air particles under the plastic and propelling the plates away with a tiny, but mighty, gust.

Last week, a Belgian-Dutch research team self-published a report advising runners and cyclists that they should take extra care while passing others on the road, warning them that respiratory droplets that could potentially contain the novel coronavirus might spread further than the 6 feet buffer recommended by public health officials.
One of the principal pleasures offered by both videogames and social media is the experience of flow . Our media culture today offers a variety of passive experiences that share a key characteristic with Csikszentmihalyi’s flow: the pleasure of losing oneself.

Dai’s work calls for a custom-designed test balloon that, pending an independent committee’s green light, is set to release up to a kilogram of calcium carbonate 12 miles above the US, in what will be the first solar geoengineering experiment in the lower atmosphere.

“Once it starts raining hard on a burn area, the things can get generated really fast, like five minutes,” says Kean.The debris flow can carry boulders and trees along with mud, making it more dangerous than a regular flood or a dry landslide.
