Shining potential of missing atoms      (via sciencedaily.com)     Original source 

Single photons have applications in quantum computation, information networks, and sensors, and these can be emitted by defects in the atomically thin insulator hexagonal boron nitride (hBN). Missing nitrogen atoms have been suggested to be the atomic structure responsible for this activity, but it is difficult to controllably remove them. A team has now shown that single atoms can be kicked out using a scanning transmission electron microscope under ultra-high vacuum.

Aluminium-ion batteries with improved storage capacity      (via sciencedaily.com)     Original source 

Scientists develop positive electrode material using an organic redox polymer based on phenothiazine. Aluminium-ion batteries containing this material stored an unprecedented 167 milliampere hours per gram, outperforming batteries using graphite as electrode material. Aluminium-ion batteries are considered a promising alternative to conventional batteries that use scarce raw materials such as lithium.

Lost giants: New study reveals the abundance decline of African megafauna      (via sciencedaily.com)     Original source 

A groundbreaking new paper focuses on the size and abundance of living and fossil African large mammals, shedding light on the ecological dynamics behind the decline of these iconic creatures. The findings challenge previous assumptions about the causes of megafaunal extinctions in Africa and provide new insights into the restructuring of ecosystems over millions of years.

Team finds reliable predictor of plant species persistence, coexistence      (via sciencedaily.com)     Original source 

Ecological scientists have long sought ways to measure and predict how specific plant communities will fare over time. Which species in a diverse population will persist and coexist? Which will decline? What factors might contribute to continuing biodiversity? Researchers report on a new method for determining whether pairs or groups of plant species are likely to coexist over time.

Saving moths may be just as important as saving the bees      (via sciencedaily.com)     Original source 

Night-time pollinators such as moths may visit just as many plants as bees, and should also be the focus of conservation and protection efforts, a new study suggests.

How studying feces may help us boost white rhino populations      (via sciencedaily.com)     Original source 

Researchers have identified significant differences in the gut microbiome of female southern white rhinos who are reproducing successfully in captivity, as compared to females who have not reproduced successfully in captivity. The work raises questions about the role that a particular genus of gut microbes may be playing in limiting captive breeding of this rhinoceros species.

Genomes of 233 primate species sequenced      (via sciencedaily.com)     Original source 

Researchers from 24 countries have analyzed the genomes of 809 individuals from 233 primate species, generating the most complete catalog of genomic information about our closest relatives to date. The project provides new insights into the evolution of primates, including humans, and their diversity. In baboons, for example, hybridization and gene flow between different species occurred in the past and is still ongoing in several regions of their range. This makes baboons a good model for the evolution of early human lineages within and outside Africa. In addition, using a specially designed AI algorithm, the genomic data enable new insights into the genetic causes of human diseases.

Symbiotic and pathogenic fungi may use similar molecular tools to manipulate plants      (via sciencedaily.com)     Original source 

Symbiotic and pathogenic fungi that interact with plants are distantly related and don't share many genetic similarities. Comparing plant pathogenic fungi and plant symbiotic fungi, scientists at the Sainsbury Laboratory Cambridge University (SLCU) have discovered that these remote relatives are using a similar group of proteins to manipulate and live within plants.

Study identifies boat strikes as a growing cause of manatee deaths in Belize      (via sciencedaily.com)     Original source 

The endangered Antillean manatee faces a growing threat from boat strikes in Belize, according to a new study that raises concerns about the survival of what had been considered a relatively healthy population. Belize hosts a population of around 1,000 manatees. With the growth of tourism in recent decades, however, Belize has seen a substantial increase in boat traffic, making boat strikes an increasingly important cause of manatee deaths and injuries.
