Published Cars, chlamydia and canines are biggest koala killers



A database tracking hospital admissions and deaths reveals the devastating impact cars, disease and dogs are having on the South East Queensland koala population.
Published Clever lapwings use cover to hide in plain sight



Ground-nesting birds called lapwings use the shape of their nests and surroundings to hide from predators, new research shows.
Published Vocal learning linked to problem solving skills and brain size



The better a songbird is at working its way around obstacles to retrieve a snack, the more complex its vocal learning ability will be.
Published New camera offers ultrafast imaging at a fraction of the normal cost


In a new paper, researchers report a camera that could offer a much less expensive way to achieve ultrafast imaging for a wide range of applications such as real-time monitoring of drug delivery or high-speed lidar systems for autonomous driving. Researchers show that their new diffraction-gated real-time ultrahigh-speed mapping (DRUM) camera can capture a dynamic event in a single exposure at 4.8 million frames per second.
Published Pollination by more than one bee species improves cherry harvest



To obtain the biggest cherry harvest, trees should be pollinated by both honey bees and mason bees. This new study shows yet another benefit of biodiversity.
Published Lack of maternal care affects development, microbiome and health of wild bees



Most wild bees are solitary, but one tiny species of carpenter bees fastidiously cares for and raises their offspring, an act that translates into huge benefits to the developing bee's microbiome, development and health, found researchers. Without maternal care the pathogen load of these developing bees ballooned -- 85 per cent of were fungi, while eight per cent were bacteria -- which can impact their microbiome, a critical component of bee health, as well as their development, immune system and gene expression.
Published Some spiders can transfer mercury contamination to land animals


Sitting calmly in their webs, many spiders wait for prey to come to them. Arachnids along lakes and rivers eat aquatic insects, such as dragonflies. But, when these insects live in mercury-contaminated waterways, they can pass the metal along to the spiders that feed on them. Now, researchers have demonstrated how some shoreline spiders can move mercury contamination from riverbeds up the food chain to land animals.
Published More Texas owls are testing positive for rat poisons


New research suggests that owls in Texas have high rates of anticoagulant rodenticides (AR) -- blood thinning rat poisons -- in their systems.
Published Movement sensors can detect disease in wild boar



Accelerometers reading the behavior of wild boars can pick up when animals are infected with a fatal virus.
Published Unlocking the genetic code of peppers: New study reveals insights into domestication and diversity



Peppers are a versatile, flavorful, and widely popular crop, used not only as a healthy food source but also for their medicinal properties. Scientists have now sequenced the genomes of key cultivated and wild pepper species, offering unprecedented insights into pepper evolution, domestication, and genetic diversity.
Published You say tomato, these scientists say evolutionary mystery



Biologists have found evidence for evolutionary 'syndromes'-- sets of traits that occur together -- that help to explain how tomatoes first evolved their distinctive blend of color, sweetness, acidity and aroma. The research not only shines a light on how fruits evolve in the wild, but will also be valuable to crop-improvement efforts aimed at breeding more nutritious and appealing varieties of fruits.
Published Super antifreeze in cells: The ability to survive in ice and snow developed in animals far earlier than we thought



More than 400 million years ago, an insect-like animal called the springtail developed a small protein that prevents its cells from freezing.
Published Lions on the brink -- New analysis reveals the differing threats to African lion populations



New results reveal that many of Africa's remaining lions live within small, fragmented populations at risk of disappearing. The researchers developed a new framework which integrates ecological and socio-political risk factors to better understand the fragility of these populations.
Published 'A crab is never just a crab'



A herring in the North Sea, a crab in the Wadden Sea or an anemone fish on a coral reef, ... biologists like to think in terms of individual species that all have their own place within food webs in ecosystems across the world. 'But that is surely too simplistic thinking,' researchers warn.
Published A new way to create germ-killing light


A research team has created an aluminum-nitride device that can convert visible light into deep-ultraviolet light through the process of second harmonic generation. This work can lead to the development of practical devices that can sterilize surfaces with ultraviolet radiation while using less energy.
Published Researchers make a significant step towards reliably processing quantum information


Using laser light, researchers have developed the most robust method currently known to control individual qubits made of the chemical element barium. The ability to reliably control a qubit is an important achievement for realizing future functional quantum computers.
Published Jackdaws switch friends to gain food -- but stick with family



Jackdaws ditch old friends and make new ones if it helps them get rewards -- but stick with family through thick and thin, new research shows.
Published Scientists find evidence of sea star species hybridization


A new study presents genomic evidence of hybridization between two closely related species of sea stars -- Asterias rubens, the common starfish, and Asterias forbesi, known as Forbes' sea star.
Published Contours that kill: Geometry influences prey capture in carnivorous pitcher plants



Researchers have shown that the shape, size, and geometry of carnivorous pitcher plants determines the type of prey they trap.
Published Valleytronics: Innovative way to store and process information up to room temperature


Researchers have found a way to maintain valley polarization at room temperature using novel materials and techniques.
