Butterfly and moth genomes mostly unchanged despite 250 million years of evolution      (via sciencedaily.com)     Original source 

Comparison of over 200 high-quality butterfly and moth genomes reveals key insights into their biology, evolution and diversification over the last 250 million years, as well as clues for conservation.

Science fiction meets reality: New technique to overcome obstructed views      (via sciencedaily.com)     Original source 

Using a single photograph, researchers created an algorithm that computes highly accurate, full-color three-dimensional reconstructions of areas behind obstacles -- a concept that can not only help prevent car crashes, but help law enforcement experts in hostage situations, search-and-rescue and strategic military efforts.

Nature's checkup: Surveying biodiversity with environmental DNA sequencing      (via sciencedaily.com)     Original source 

A thousand kilometers south of Tokyo, far into the largest ocean on Earth, lies a chain of small, volcanic islands -- the Ogasawara Islands. Nature has been able to develop on its own terms here, far from both humans and the warm Kuroshio current, which acts like a shuttle, moving marine species from Taiwan, over the Ryukyu Islands, and up the Pacific coast of mainland Japan. With upwards of 70 % of trees and many animal species being endemic to the archipelago, the islands have been dubbed 'the Galapagos of the East', as they are valuable as both a biodiversity hotspot and a cradle of scientific discovery.

Spy-satellite images offer insights into historical ecosystem changes      (via sciencedaily.com)     Original source 

New study advocates the use of more than one million declassified images for ecology and conservation. The images can offer better insights into the historical changes of ecosystems, species populations or changes in human influences on the environment dating back to the 1960s. Collaboration between ecologists, conservationists, and remote sensing experts is necessary to explore the full potential of the data.

Giant Antarctic sea spiders reproductive mystery solved      (via sciencedaily.com)     Original source 

Instead of carrying the babies until they hatched, as in most species of sea spiders, one parent (likely the father) spent two days attaching the eggs to the rocky bottom where they developed for several months before hatching as tiny larvae.

New chip opens door to AI computing at light speed      (via sciencedaily.com)     Original source 

Engineers have developed a new chip that uses light waves, rather than electricity, to perform the complex math essential to training AI. The chip has the potential to radically accelerate the processing speed of computers while also reducing their energy consumption.

1,000 atomic qubits and rising      (via sciencedaily.com)     Original source 

Making quantum systems more scalable is one of the key requirements for the further development of quantum computers because the advantages they offer become increasingly evident as the systems are scaled up. Researchers have recently taken a decisive step towards achieving this goal.

Reforestation programs could threaten vast area of tropical grasslands      (via sciencedaily.com)     Original source 

New research reveals the scale of inappropriate reforestation projects across Africa. A new study reveals that an area the size of France is threatened by forest restoration initiatives, such as the AFR100 initiative (African Forest Landscape Restoration Initiative), due to inappropriate restoration in the form of tree-planting.

Researchers shed light on river resiliency to flooding      (via sciencedaily.com)     Original source 

Researchers have completed one of the most extensive river resilience studies, examining how river ecosystems recover following floods. They developed a novel modeling approach that used data from oxygen sensors placed in rivers to estimate daily growth in aquatic plants and algae. The researchers then modeled the algal and plant biomass in 143 rivers across the contiguous U.S. to quantify what magnitude of flooding disturbs the biomass and how long the rivers take to recover from floods. Increased understanding of rivers' resiliency is important to maintaining healthy rivers, as human actions can affect flood regimes and change the conditions in rivers for other aquatic life that may rely on algae and plants as a food source.

Cold-water coral traps itself on mountains in the deep sea      (via sciencedaily.com)     Original source 

Corals searching for food in the cold and dark waters of the deep sea are building higher and higher mountains to get closer to the source of their food. But in doing so, they may find themselves trapped when the climate changes.

Is the Amazon forest approaching a tipping point?      (via sciencedaily.com)     Original source 

Global warming may be interacting with regional rainfall and deforestation to accelerate forest loss in the Amazon, pushing it towards partial or total collapse. New research has identified the potential thresholds of these stressors, showing where their combined effects could produce a 'tipping point' -- in which the forest is so fragile that just a small disturbance could cause an abrupt shift in the state of the ecosystem.

Joro spiders well-poised to populate cities      (via sciencedaily.com)     Original source 

The Joro spider was first spotted stateside around 2013 and has since been spotted across Georgia and the Southeast. New research has found more clues as to why the spider has been so successful in its spread. The study found the invasive orb-weaving spider is surprisingly tolerant of the vibrations and noise common in urban landscapes. In this new study, researchers examined how Joro spiders can live next to busy roads, which are notably stressful environments for many animals.
