Physicists create quantum-inspired optical sensorResearchers from the Moscow Institute of Physics and Technology, joined by a colleague from Argonne National Laboratory, U.S., have implemented an advanced quantum algorithm for measuring physical quantities using simple optical tools. Published in Scientific Reports, their study takes us a step closer to affordable linear optics-based sensors with high performance characteristics. Such tools are sought after in diverse research fields, from astronomy to biology.
redHUMAN: Deciphering links between genes and metabolismIn the last two decades, the life sciences have seen a growing partnership with information technology. The main drive behind this is the need to process and integrate enormous volumes of data from different fields including genetics, biochemistry, cell and molecular biology, and physiology in order to gain a deeper understanding of biological systems, processes, and even entire organisms.
Footage captured of cephalopod at deepest ocean level ever observedA pair of researchers, one with Newcastle University in the U.K, the other the National Museum of Natural History in Washington D.C., has captured video footage of a cephalopod at the deepest ocean level ever observed. In their paper published in the journal Marine Biology, Alan Jamieson and Michael Vecchione describe how they used "landers" to capture video remotely at the bottom of the Indian Ocean, and what they found.
Did life emerge in the 'primordial soup' via DNA or RNA? Maybe bothScientists have long debated which genetic information carrier—DNA or RNA—started life on Earth, but a new study suggests life could have begun with a bit of both. The research, led by scientists from the Medical Research Council (MRC) Laboratory of Molecular Biology (LMB), in Cambridge, shows for the first time how some of the building blocks of both DNA and RNA could have spontaneously formed and co-existed in the 'primordial soup' on Earth.
Interfacing synthetic biology with microelectronicsNew research demonstrates the integration of synthetic biology with electronic circuitry through engineered population dynamics that regulate the accumulation of charged metabolites. The resulting sensor devices can detect changes in bacterial population in response to the presence of chemicals, light or pH. Connecting bacterial gene expression to electrodes is an appealing approach to interface...
Scientists Captured New Footage of the Deepest-Living OctopusScientists have discovered a potentially new species of the adorable “dumbo” octopus in a very unique place. At more than 4 miles (6,957 meters) under the Indian Ocean, the newly discovered octo was found at the deepest depths of any cephalopod has been observed. The discovery—published in the journal Marine Biology Tuesday—signals that there’s still so much to learn about these creatures and the deep sea. It’s a reminder that not all deep-sea animals have spiky teeth and weird bioluminescence. Some are pretty damn cute.1
Ursula K. Le Guin, The Art of Fiction No. 221In the early 1960s, when Ursula K. Le Guin began to publish, science fiction was dominated by so-called hard sci-fi: speculative fiction grounded in physics, chemistry, and, to a lesser extent, biology. The understanding of technological progress as an unalloyed good went largely unquestioned; Ameri...
Researchers develop biotechnological process for jasmonic acid productionPlants produce the hormone jasmonic acid as a defence response when challenged, making their leaves taste bad to predators. Biologists want to determine whether biological precursors and other variants of jasmonic acid lead to similar or different effects. But such derivatives of the hormone have so far been too expensive for experiments and difficult to come by. Researchers from the Faculties of Chemistry and Biology at Bielefeld University have now developed a method to make the production of a biologically significant precursor of jasmonic acid more efficient and cheaper. Their innovation: They imitated how plants produce the hormone. The result is 12-OPDA, a central precursor of jasmonic acid. In the long term, it could also be a potential precursor for high-quality perfume. The researchers published their method on May 29 in the research journal Advanced Science.
Cellular players get their moment in the limelightIn order to understand our biology, researchers need to investigate not only what cells are doing, but also more specifically what is happening inside of cells at the level of organelles, the specialized structures that perform unique tasks to keep the cell functioning. However, most methods for analysis take place at the level of the whole cell. Because a specific organelle might make up only a fraction of an already microscopic cell's contents, "background noise" from other cellular components can drown out useful information about the organelle being studied, such as changes in the organelle's protein or metabolite levels in response to different conditions.
Women with Neandertal gene give birth to more childrenOne in three women in Europe inherited the receptor for progesterone from Neandertals—a gene variant associated with increased fertility, fewer bleedings during early pregnancy and fewer miscarriages. This is according to a study published in Molecular Biology and Evolution by researchers at the Max Planck Institute for Evolutionary Anthropology in Germany and Karolinska Institutet in Sweden.
