An alarming study that claimed the gene-editing technique CRISPR could produce hundreds of unexpected mutations in edited genomes has now been followed up by its authors, who say they cannot replicate their controversial result. The acknowledgment – which comes in a report of new mice experiments that didn’t introduce such mutations – isn’t technically a retraction of their earlier findings, but […]

This soft robotic fish is reef friendly and won’t scare away the real thing Robert Katzschmann et al. (Photo: Joseph DelPreto), MIT CSAIL Fish, like most animals, have a pretty good idea of which other animals they’re cool with, and which animals they’re not. Very few animals are cool with humans, and fish are no […]

Over the objections of the authors, PLOS ONE has retracted a paper linking a diet designed to restore healthy gut bacteria to weight loss and other benefits. The study, published in June 2017, claimed to show that a “Microbiome restoration diet improves digestion, cognition and physical and emotional wellbeing.” The diet was one championed by The Gut […]

The long-standing mystery of why comets give off X-ray emission has been solved by a group of experimental physicists led by the University of Oxford, UK. On October 19, 2014, Comet Siding Spring made a remarkably close encounter with Mars, buzzing the planet at just one third of the Earth-Moon distance. Image credit: NASA’s Goddard […]

HIV-1 envelope glycoproteins (Env) represent the only virus-specific antigen exposed at the surface of infected cells. In its unliganded form, Env from primary viruses samples a ‘closed’ conformation (State 1), which is preferentially recognized by broadly neutralizing antibodies (bNAbs). CD4 engagement drives Env into an intermediate ‘partially open’ (State 2) and then into the ‘open’ […]

AMES, Iowa – If you’ve enjoyed some spicy food lately, you might have a bird to thank. A new study involving Iowa State University researchers explores how a mutualistic, or mutually beneficial, relationship between birds and chili peppers in the Mariana Islands helps chili peppers grow in the wild. The study, published in the peer-reviewed […]

Roteins are the worker bees of the cell, mainly ganging up to form macromolecular, multicomponent complexes to perform intricate cellular tasks. Trying to characterize such protein complexes and all of their functions within organisms is a discipline called “proteomics.” Historically, scientists have studied the form and function of proteins by dissolving them with enzymes and sequencing the […]

For the first time, researchers have succeeded in integrating artificial organelles into the cells of living zebrafish embryos. UNIVERSITY OF BASEL For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of living zebrafish embryos. This innovative approach using artificial organelles as cellular implants […]

The treatable and curable disease is on the rise in New York City, and an alarming number of latent cases are lurking. LUKE MACGREGOR / REUTERS The number of tuberculosis cases is at its lowest point since the Centers for Disease Control and Prevention began reporting it in 1953. But the decline is far from enough to […]

A research group in China has identified a group of gut microbiota that can alleviate the symptoms of type 2 diabetes in patients consuming a diet high in fiber. AsianScientist (Mar. 20, 2018) – In a study published in Science, scientists in China have identified a specific group of gut bacteria that can help relieve […]
