"We have watched and waited for this moment." World-first footage shows orangutan using canopy bridge to cross a road in North Sumatra | Discover Wildlife
The orangutan can be seen carefully making his way along the rope structure, which was put up two years ago to provide the large primates with safe passage between forest fragments.

Excited to share our new paper in L&O Letters on #GreenhouseGas emissions! 🧪 aslopubs.onlinelibrary.wiley.com/doi/10.1002/... We found that nutrient enrichment 🌱, combined with weather disturbances ⛈️, accelerated the timing, but not magnitude, of summer #methane and CO2 emissions from ponds👩‍🔬

Immediate and cumulative effects of nutrient and extreme weather disturbances on pond greenhouse gas emissions
Ponds are significant emitters of greenhouse gases (GHGs). While eutrophication stimulates GHG emissions, responses to nutrient pulses and weather events are less clear. We investigated both immediat...

Scientists Found Strange "Modern" Structures on the Arctic Seafloor That Should Not Physically Exist
Researchers descending into giant craters on the seafloor found structures that had no right to be there, modern, active, and completely absent from every map ever made of this region.

New research shows how marine heatwaves have hidden depths: “Marine heatwaves are damaging to critical ecosystems like coral reefs, driving mass bleaching events like the five we have seen on the Great Barrier Reef since 2016. We need to keep building our understanding of them through sustained and targeted monitoring. This can inform management actions,” said Dr Benthuysen.
