Cosmic lockdown: How the environment can isolate quantum fields
A simplified cosmological model suggests that decoherence can suppress quantum tunneling, effectively locking fields into the vacuum state they have reached.

Elastic fantastic: The deadly fluid of pitcher plants
In the world of carnivorous plants, Venus flytraps—with their showy, snapping reflexes—have long hogged the limelight. But plants have many creative bug-capture strategies, from slippery waxes to vibrating lids to bizarrely textured fluids.

How cities can go greener in a warming climate
VUB researcher Robbe Neyns has developed artificial intelligence capable of identifying trees down to the species level in satellite and aerial imagery. The technology can help cities better map their trees and biodiversity, making the urban environment as livable as possible, particularly in the face of a warming climate.

Q&A: Grasslands in more diverse landscapes can suffer less from drought
During the heat wave of 2018, meadows and pastures also suffered from drought. Are grasslands in diverse landscapes more resilient to yield losses than those in monotonous regions? Researchers at the University of Bonn, led by Marco Ferro and Dr. Jan Börner from the Institute for Food and Resource Economics (ILR), investigated the influence of landscape diversity on the drought tolerance of grasslands as part of Collaborative Research Center 1502 DETECT. The work is published in the American Journal of Agricultural Economics.

Why winter cold spells are getting milder
The Beast from the East ravaged much of the U.K. and Europe in February and March 2018, bringing severe storms, snow showers and bitter winds. But as the climate changes, rising average temperatures will affect the severity of extremely cold weather like this.

Mapping wildfire risk across the US, day by day
Wildfires can spread fastest when they tear through areas of dry vegetation. In contrast, vegetation that contains a lot of moisture can slow a wildfire's advance and give firefighting crews precious time to contain the blaze.

Biodiversity in production forests: Both costs and benefits shape the financial picture
Forests provide timber as well as many other ecosystem services. An important question is how measures to conserve biodiversity affect the profitability of forest operations focused on wood production. Researchers from Wageningen University & Research and the University of Freiburg reviewed studies worldwide that compared forest management with biodiversity conservation measures against business-as-usual management without those measures. The work is published in the journal Current Forestry Reports.
