All Science discoveries →From remedy to prevention: Researchers call for proactive approach to protect the human right to water
More than 2 billion people, or approximately one-quarter of the world's population, lack access to safe water, sanitation and hygiene, according to the United Nations Children's Fund. Today, 16 years after the U.N. General Assembly recognized this access as a fundamental human right, its legal protection is well established, but the reality on the ground lags behind.
Chip identifies cells by their electrical signature, then separates them with a precisely aimed sound wave
In biomedicine, sorting cells accurately without damaging them remains a persistent problem. Current methods, like fluorescence-activated cell sorting, rely on labeling the cells extrinsically, which can stress the cells, alter their behavior and even interfere with the assay. A collaborative study between researchers in Singapore and China has now developed a noninvasive, label-free method to sort cells.
Scientists challenge the dream of bringing extinct species back to life
Could extinction itself become a thing of the past? Advances in biotechnology, including ancient DNA sequencing, genome analysis and gene editing, have led some to believe that it may be possible to bring extinct species back to life.
Biodegradable bubble moves away from lactic acid without a motor—a step toward artificial cells
A tiny biodegradable bubble can move away from a chemical on its own, without a motor. Living cells need complex molecular machinery to do this. This discovery by researchers led by chemist Daniela Wilson at Radboud University, together with colleagues at Durham University, is a step toward artificial cells with lifelike behavior and could, in the long term, provide an interesting approach for self-steering particles in targeted drug delivery.
Biologists reveal chlorophyll-building enzyme's structure for first time and clarify its mechanism
Plants are green because of a pigment that is key to photosynthesis: chlorophyll. In its production, the enzyme chlorophyll synthase plays an important role. As part of an international collaboration, researchers from Osnabrück University, the Center Algatech in Třeboň and the University of Sheffield have now succeeded in deciphering the structure of this enzyme and gaining valuable insights into its mechanism. The findings are published in the journal Nature Chemical Biology.
When rain finally does come to drylands, only some microbes in the soil 'awaken'
In arid regions, the microbes that power threatened dryland soil ecosystems called biological soil crusts stay dormant over long periods, only "awakening" when they sense moisture from infrequent rainfall. Now, a team led by researchers at Penn State—driven by projections that those biocrusts will decline by as much as 40% in the next 45 years—found that when a dryland soil does get wet, most of the microbes in the biocrust stay inactive. It's a discovery that will inform ongoing efforts to conserve and restore biocrusts, according to the researchers.
