Published Keep it secret: Cloud data storage security approach taps quantum physics



Distributed cloud storage is a hot topic for security researchers, and a team is now merging quantum physics with mature cryptography and storage techniques to achieve a cost-effective cloud storage solution.
Published Evolution of taste: Early sharks were able to perceive bitter substances



New genetic data show that humans and sharks share bitter taste receptors, even though their evolutionary pathways separated nearly 500 million years ago.
Published New discovery on how green algae count cell divisions illuminates key step needed for the evolution of multicellular life



An international research team has made an unexpected discovery of a biased counting mechanism used by the single-celled green alga Chlamydomonas to control cell division.
Published Atomic dance gives rise to a magnet



Researchers turned a paramagnetic material into a magnet by manipulating electrons' spin via atomic motion.
Published Scientists use quantum biology, AI to sharpen genome editing tool



Scientists used their expertise in quantum biology, artificial intelligence and bioengineering to improve how CRISPR Cas9 genome editing tools work on organisms like microbes that can be modified to produce renewable fuels and chemicals.
Published Bacteria-virus arms race provides rare window into rapid and complex evolution



Rather than a slow, gradual process as Darwin envisioned, biologists can now see how evolutionary changes unfold on much more accelerated timescales. Using an accelerated arms race between bacteria and viruses, researchers are documenting rapid evolutionary processes in simple laboratory flasks in only three weeks.
Published Poison dart frogs: Personality determines reproductive strategies



Unlike their relatives, individuals of the poison frog Allobates femoralis are not poisonous but are captivating due to their different behavioral profiles: They successfully reproduce with different strategies depending on whether they are bold, aggressive or explorative. In addition, certain character traits are already present in this species at the tadpole stage.
Published Head lice evolution mirrors human migration and colonization in the Americas



A new analysis of lice genetic diversity suggests that lice came to the Americas twice -- once during the first wave of human migration across the Bering Strait, and again during European colonization.
Published Yeast with an over half synthetic genome is created in the lab



Researchers have combined over seven synthetic chromosomes that were made in the lab into a single yeast cell, resulting in a strain with more than 50% synthetic DNA that survives and replicates similarly to wild yeast strains. A global consortium is working to develop the first synthetic eukaryote genome from scratch. The team has now synthesized and debugged all sixteen yeast chromosomes.
Published Scientists take major step towards completing the world's first synthetic yeast



A team of Scientists has completed construction of a synthetic chromosome as part of a major international project to build the world's first synthetic yeast genome. The work represents completion of one of the 16 chromosomes of the yeast genome, which is part of the biggest project ever in synthetic biology; the international synthetic yeast genome collaboration. The collaboration, known as 'Sc2.0' has been a 15-year project involving teams from around the world (UK, US, China, Singapore, UK, France and Australia), working together to make synthetic versions of all of yeast's chromosomes. Alongside this paper, another 9 publications are also released today from other teams describing their synthetic chromosomes. The final completion of the genome project -- the largest synthetic genome ever -- is expected next year.
Published Cracking the code: Genome sequencing reveals why songbirds are larger in colder climates



Scientists have unlocked the genetic basis underlying the remarkable variation in body size observed in song sparrows, one of North America's most familiar and beloved songbirds. This discovery also provides insights into this species' capacity to adapt to the challenges of climate change. The study used genomic sequencing to successfully pinpoint eight genetic variants, or DNA mutations, largely responsible for the nearly threefold difference in body size observed across the song sparrow range from Mexico to Alaska.
Published 450-million-year-old organism finds new life in Softbotics



Researchers have used fossil evidence to engineer a soft robotic replica of pleurocystitids, a marine organism that existed nearly 450 million years ago and is believed to be one of the first echinoderms capable of movement using a muscular stem.
Published Video technology could transform how scientists monitor changes in species evolution and development



New research combines microscope and video technology to analyze how different species develop, and how changes in the timings of any developments can be tracked. A detailed analysis of the Energy Proxy Traits (EPTs) that result from these processes has provided researchers with the first evidence that traditionally measured timings of developmental events are associated with far broader changes to the full set of an embryo's observable characteristics.
Published Fossils tell tale of last primate to inhabit North America before humans



Paleontologists have shed light on the long-standing saga of Ekgmowechashala, based on fossil teeth and jaws found in both Nebraska and China. Ekgmowechashala is the last primate found in the fossil record before humans.
Published Vacuum in optical cavity can change material's magnetic state without laser excitation



Researchers in Germany and the USA have produced the first theoretical demonstration that the magnetic state of an atomically thin material, ?-RuCl3, can be controlled solely by placing it into an optical cavity. Crucially, the cavity vacuum fluctuations alone are sufficient to change the material's magnetic order from a zigzag antiferromagnet into a ferromagnet.
Published New secrets about cat evolution revealed



By comparing genomes of several cat species, the project has helped researchers understand why cat genomes tend to have fewer complex genetic variations (such as rearrangements of DNA segments) than other mammal groups, like primates. It also revealed new insights into which parts of cat DNA are most likely to evolve rapidly and how they play a role in species differentiation.
Published Research outlines how sex differences have evolved



Researchers have shown that sex differences in animals vary dramatically across species, organs and developmental stages, and evolve quickly at the gene level but slowly at the cell type level.
Published Adult coral can handle more heat and keep growing thanks to heat-evolved symbionts



Adult fragments of a coral species can better tolerate bleaching and recover faster when treated with tougher heat-evolved symbionts, new research indicates. The study also found that treatment with the heat-evolved symbionts did not compromise the coral's ability to grow. This differs from previous studies on Great Barrier Reef corals which found that naturally heat tolerant symbionts could enhance heat resistance in adult corals, but at a cost to its growth.
Published What a '2D' quantum superfluid feels like to the touch



Researchers have discovered how superfluid helium 3He would feel if you could put your hand into it. The interface between the exotic world of quantum physics and classical physics of the human experience is one of the major open problems in modern physics. Nobody has been able to answer this question during the 100-year history of quantum physics.
Published Optical-fiber based single-photon light source at room temperature for next-generation quantum processing



Single-photon emitters quantum mechanically connect quantum bits (or qubits) between nodes in quantum networks. They are typically made by embedding rare-earth elements in optical fibers at extremely low temperatures. Now, researchers have developed an ytterbium-doped optical fiber at room temperature. By avoiding the need for expensive cooling solutions, the proposed method offers a cost-effective platform for photonic quantum applications.
