Measuring the properties of light: Scientists realize new method for determining quantum states      (via sciencedaily.com)     Original source 

Scientists have used a new method to determine the characteristics of optical, i.e. light-based, quantum states. For the first time, they are using certain photon detectors -- devices that can detect individual light particles -- for so-called homodyne detection. The ability to characterize optical quantum states makes the method an essential tool for quantum information processing.

Increasingly similar or different? Centuries-long analysis suggests biodiversity is differentiating and homogenizing to a comparable extent      (via sciencedaily.com)     Original source 

The tendency of communities and the species within them to become more similar or more distinct across landscapes -- biotic homogenization and differentiation -- are approximately balanced, according to a new study. This analysis is the first of its kind to provide a comprehensive assessment of how local and regional biodiversity changes combine across landscapes over centuries.

Converting rainforest to plantation impacts food webs and biodiversity      (via sciencedaily.com)     Original source 

Every day, new areas of rainforests are converted into plantations, drastically changing tropical biodiversity and the way the ecosystem functions. Yet, the current understanding of the consequences is fragmentary: previous studies tended to examine either biodiversity or the ecosystem. An international research team brings these threads together in this study. They analyzed organisms ranging from microscopic mites and earthworms in the soil, to beetles and birds in tree canopies, comparing tropical rainforest with rubber and oil palm plantations in Sumatra, Indonesia.

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.

Genetic insights and conservation challenges of Nara's sacred deer      (via sciencedaily.com)     Original source 

In Nara, Japan, the revered sika deer faces a dilemma as their escalating population damages local farmlands. A new study has revealed a complex situation: while the sanctuary's deer upholds a distinct genetic identity, the surrounding areas display a blend of genetic lineages. This exposes a pressing predicament: whether to cull the 'pest' deer around sanctuary or risk losing a sacred genetic legacy.

New research has shown that the tropical subsurface ocean gained oxygen during the Paleocene-Eocene Thermal Maximum (commonly referred to as PETM). During this short-lived interval of time in Earth s history that occurred 56 million years ago the average temperatures rose by up to six degrees within a few thousand years.

A new design for quantum computers      (via sciencedaily.com)     Original source 

Creating a quantum computer powerful enough to tackle problems we cannot solve with current computers remains a big challenge for quantum physicists. A well-functioning quantum simulator -- a specific type of quantum computer -- could lead to new discoveries about how the world works at the smallest scales. Quantum scientists have developed a guide on how to upgrade these machines so that they can simulate even more complex quantum systems.
