What math tells us about social dilemmas      (via sciencedaily.com)     Original source 

Human coexistence depends on cooperation. Individuals have different motivations and reasons to collaborate, resulting in social dilemmas, such as the well-known prisoner's dilemma. Scientists now present a new mathematical principle that helps to understand the cooperation of individuals with different characteristics.

Improving efficiency, reliability of AI medical summarization tools      (via sciencedaily.com)     Original source 

Medical summarization, a process that uses artificial intelligence (AI) to condense complex patient information, is currently used in health care settings for tasks such as creating electronic health records and simplifying medical text for insurance claims processing. While the practice is intended to create efficiencies, it can be labor-intensive, according researchers who created a new method to streamline the way AI creates these summaries, efficiently producing more reliable results.

Mice surprise: Researchers discover new native species      (via sciencedaily.com)     Original source 

Australia can lay claim to two new species of native rodent thanks to a new study. The aptly named delicate mouse was previously thought to be a single species spanning a massive stretch of the country from the Pilbara in Western Australia, across parts of the Northern Territory and through Queensland down to the New South Wales border. We now know there are three distinct species.

Plasma scientists develop computer programs that could reduce the cost of microchips and stimulate American manufacturing      (via sciencedaily.com)     Original source 

Fashioned from the same element found in sand and covered by intricate patterns, microchips power smartphones, augment appliances and aid the operation of cars and airplanes. Now, scientists are developing computer simulation codes that will outperform current simulation techniques and aid the production of microchips using plasma, the electrically charged state of matter also used in fusion research. These codes could help increase the efficiency of the manufacturing process and potentially stimulate the renaissance of the chip industry in the United States.

Accelerating the discovery of single-molecule magnets with deep learning      (via sciencedaily.com)     Original source 

Single-molecule magnets (SMMs) are exciting materials. In a recent breakthrough, researchers have used deep learning to predict SMMs from 20,000 metal complexes. The predictions were made solely based on the crystal structures of these metal complexes, thus eliminating the need for time-consuming experiments and complex simulations. As a result, this method is expected to accelerate the development of functional materials, especially for high-density memory and quantum computing devices.

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.

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.
