Swarming Drones Autonomously Navigate a Dense Forest
Chinese researchers show off a swarm of drones collectively navigating a dense forest they've never encountered. TechCrunch reports: Researchers at Zheijang University in Hangzhou have succeeded, however, with a 10-strong drone swarm smart enough to.....»»
Coffee, child labor, and education: Examining a triple social–ecological trade-off in an Afromontane forest landscape
The work with forest preservation in southwestern Ethiopia, where smallholder coffee farmers play an important part, is essential for global sustainability. But there are also negative consequence to the synergy between smallholder cash crop producti.....»»
Bird diversity increased in severely burned forests of southern Appalachian mountains
A new study found bird diversity increased in North Carolina mountain forest areas severely burned by wildfire in 2016, reinforcing that while wildfire can pose risks to safety and property, it can be beneficial to wildlife. The study results could h.....»»
Researchers develop all-optical approach to pumping chip-based nanolasers
Researchers have developed a new all-optical method for driving multiple highly dense nanolaser arrays. The approach could enable chip-based optical communication links that process and move data faster than today's electronic-based devices......»»
Researchers pioneer biocompatible all-water "Aquabots"
Soft robots have phenomenally advanced in recent years. Microscale soft robots designated to navigate difficult paths and perform biological functions in the human body could have profound potential biomedical applications such as surgery, prosthetic.....»»
Ukraine war: Drones are transforming the conflict, bringing Russia on to the frontline
Nato secretary-general Jens Stoltenberg spoke recently of his fear that the war in Ukraine could spin out of control into a full-blown confrontation between Russia and the west. "If things go wrong, they can go horribly wrong," he told Norwegian broa.....»»
RLSS drone trial to help sea swimmers in trouble
The Royal Life Saving Society is trialling the use of buoyancy-aid-deploying drones......»»
Bat diversity and abundance are highest in old deciduous forest stands on river banks in Eastern Ukraine
European forest-dwelling bats require complex woodland structures at both the micro-habitat and the landscape level for successful breeding in summer. Particularly, the results from Kharkiv region (Eastern Ukraine) demonstrate that large stands of ma.....»»
New DJI Mini 3 drone is a tiny drone that can shoot 4K HDR video
The DJI Mini 3 is the latest addition to the DJI mini lineup of tiny, lightweight drones and has 4k HDR capabilities.New DJI Mini 3 droneDJI specifically designed the Mini 3 to weigh under 249 grams, but its size doesn't reflect its capabilities. The.....»»
How the UN’s ‘Sex Agency’ Uses Tech to Save Mothers’ Lives
Big Data, drones, diagnostics—the United Nations and other groups hope to innovate the world out of a maternal and reproductive health crisis......»»
Hubble captures globular cluster NGC 2031
In the top left corner of this starry sight, the globular cluster NGC 2031 shines brilliantly. This dense group of thousands of stars is held together in a spherical shape by its stars' mutual gravitational attraction. The cluster is located in the c.....»»
Forest wildflowers and their overstory trees are changing with climate, but not always keeping pace
For spring ephemerals, timing is everything. These special wildflowers grow in temperate forests around the world, early in spring before the trees leaf out. Come out too early and it's still winter, too late and it's too shady under the forest canop.....»»
How tree species link fungal partners across a large-scale forest ecosystem
In a study published in Science China Life Sciences, a team surveyed hyper-diverse fungal communities in approximately 500 paired leaf and soil samples, which were associated with 55 tree species that are located over 2,000-km span of mountain forest.....»»
Estimating forest desiccation to better predict fire danger
Desiccation of tree foliage is a key factor in the spread of fires. However, during droughts, changes in the water content of forest canopies remain poorly understood. Scientists from INRAE and the CNRS have developed the first model to predict canop.....»»
Forest resilience linked with higher mortality risk in western U.S., study finds
A forest's resilience, or ability to absorb environmental disturbances, has long been thought to be a boost for its odds of survival against the looming threat of climate change......»»
Climate change in the forests of northern Germany: Team finds widespread drought stress in European beech
More and more trees are suffering the consequences of decades of manmade climate change. The growth of the European beech has so far suffered decline mainly in southern Europe. European beech is Germany's most important native forest tree species, an.....»»
US Forest Service is the latest government agency to try electric trucks
By 2027, all light-duty vehicles bought by the federal government must be EVs. Enlarge / I wonder if the US Forest Service will like the F-150 Lightning as much as everyone else who drives one? (credit: US Forest Service).....»»
Climate change supercharges threat from forest-eating bug
Deep in the Finnish woods, the moss and blueberry shrubs hide a deadly threat to the boreal forests that are as important to the planet as the Amazon rainforest......»»
With a small network of satellites around Mars, rovers could navigate autonomously
When it comes to "on the ground" exploration of Mars, rovers make pretty good advance scouts. From Pathfinder to Perseverance, we've watched as these semi-autonomous robots do what human explorers want to do in the future. Now, engineers are studying.....»»
Individual tree-based model constructed for multiscale forest carbon dynamics prediction
Forests contribute an enormous carbon flux to terrestrial ecosystems. Thus, accurate estimation and prediction of forest dynamics both play an important role in understanding the carbon cycle in the background of global change. Process-based ecologic.....»»
Large terrestrial mammals are more vulnerable to acoustic impact of drones than to visual impact
Large terrestrial mammals are vulnerable to the acoustic sounds of drones, technological systems which are increasingly used to study the wildlife in open habitats such as the savanna and marshes......»»
