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.....»»
A true view of infant star clusters
Super star clusters (SSCs) are dense clusters of bright young stars. As they evolve their intense radiation can clear gas and dust from their region. But as they are forming the region around them is still undisturbed. Because of dense gas and dust s.....»»
The chaotic cores of Perseus protostars
The formation of a star has a simple tale. A region of interstellar gas collapses under its own weight, eventually forming a dense protostar surrounded by a disk of gas and dust. The protostar and the disk rotate in the same plane, and often jets of.....»»
Tokamak experiments provide unique data for validating spacecraft heat shield ablation models
When a spacecraft enters a thick atmosphere at a high velocity, it rapidly compresses the gas in front of it. This creates temperatures high enough to ionize the gas molecules into a hot, dense plasma. To protect against damage, spacecraft are typica.....»»
US government examining over 500 "UFO" reports
The US government is examining 510 UFO reports, over triple the number in its 2021 file, and while many were caused by drones or balloons, hundreds remain unexplained, according to a report released Thursday......»»
How did the Butterfly Nebula get its wings? It"s complicated
Planetary nebulae form when red giant stars expel their outermost layers as they run out of helium fuel—becoming hot, dense white dwarf stars that are roughly the size of Earth. The material that was shed, enriched in carbon, forms dazzling pattern.....»»
Sounding the alarm in time to save endangered species
A few years—or sometimes even just a few weeks—can be all it takes for a plant or animal to acquire "endangered species" status. For instance, when a new road is built through a forest, the chainsaws come out and a rare species of amphibian may b.....»»
Study shows variable-density planting can be a cost-effective tool for weed control
High-density crop planting is a proven approach for suppressing patches of weeds that escape other controls. Unfortunately, though, the cost of seed keeps many growers from considering this dense planting strategy......»»
Urban forest-mapping with help from public and private data
A Concordia project cataloging the diversity of the urban forest in a Montreal residential neighborhood is now complete, and the researchers behind it say the results highlight the importance of a diverse city tree population......»»
Research student helps build radio source catalog
Bailee Wolf, a student at The Ohio State University, has a tool to better process radio data, and it could help future spacecraft navigate through the solar system......»»
Indigenous territories and protected areas are key to forest conservation in the Brazilian Amazon, study shows
A study led by researchers with the Center for Earth Observation and Modeling at the University of Oklahoma analyzed time series satellite images from 2000 to 2021, revealing the vital role of Indigenous territories and protected areas in forest cons.....»»
Quiet, please: Human noise is interfering with the sex lives of grasshoppers
Grasshoppers have a bad reputation. They're not popular with gardeners And locusts, a type of swarming grasshopper, can do huge damage to vegetation and crops when they're in a feeding frenzy......»»
New Indonesia capital imperils ancient Eden with "ecological disaster"
The twisting road that leads to Indonesia's future capital is lined with dense rainforest and pockets of plantations, punctuated every so often with monkeys enjoying a laze out on the tarmac......»»
Internships have positive results but do little to influence long-term diversity in USDA Forest Service
A growing number of student and recent graduate trainee and internship programs have been implemented over the last few decades as one potential solution to address the underrepresentation of women and Black, Indigenous, and People of Color (BIPOC) i.....»»

During mesenchymal migration, a cancer cell moves like a gecko on a wall......»»
Venus may have Earth-like lithospheric thickness and heat flow
Poor old Venera 9, the Soviet Union's Venus lander, separated from its orbiter and made a hot, violent descent through the dense Venusian atmosphere on October 22, 1975, landing hard on a circular shield designed to crumple and absorb the impact. It.....»»
This Christmas, It’s ‘Firmageddon’ as Climate Change Hits Oregon
More than a million acres of state forest contain trees that have succumbed to stressors exacerbated by a multiyear drought.....»»
Trees could be key protagonist for forest-grassland transitions
A study investigating the transition from forests to savannas and vice versa has found that trees could be the key protagonists......»»

NASA developing AI to navigate the lunar surface using landmarks
Much like how familiar landmarks can give travelers a sense of direction when their smart phones lose their lock on GPS signals, a NASA engineer is teaching a machine to use features on the Moon's horizon to navigate across the lunar surface......»»
