Towable sensor free-falls to measure vertical slices of ocean conditions Posted: 21 May 2020 01:12 PM PDT Towable sensor free-falls to measure vertical slices of ocean conditions. |
Low-severity fires enhance long-term carbon retention of peatlands Posted: 21 May 2020 01:12 PM PDT High-intensity fires can destroy marshy peatlands and cause them to emit huge amounts of their stored carbon into the atmosphere as greenhouse gases, but a new study finds low-severity fires spark the opposite outcome. By creating a decay-inhibiting crust on clumps of moist soil particles within the peatland, the smaller surface fires help protect the stored carbon and enhance peatlands' long-term storage of it, even during times of extreme drought. |
New Army 3-D printing study shows promise for predictive maintenance Posted: 21 May 2020 12:19 PM PDT Researchers have discovered a way to monitor the performance of 3D printed parts, which tend to have imperfections that affect performance in ways traditionally-machined parts do not. |
The European viper uses cloak-and-dazzle to escape predators Posted: 21 May 2020 12:19 PM PDT Research demonstrates that the characteristic zig-zag pattern on a viper's back performs opposing functions during a predation event. At first, the zig-zag pattern helps the snake remain undetected. But upon exposure, it provides a conspicuous warning of the snake's dangerous defense. Most importantly the zig-zag can also produce an illusionary effect that may hide the snake's movement as it flees. |
