Girolline, a compound extracted from the sea sponge Pseudaxinyssa cantharella, has been investigated for possible antitumor effects and also found to have anti-malarial effects. https://phys.org/news/2025-01-scientists-compound-sea-sponge-exerts.html Biochemistry Tue, 14 Jan 2025 09:40:03 EST news656070001 Pangenomes are collections of annotated genome sequences of multiple individuals of a species. The structural variants uncovered by these datasets are a major asset to genetic analysis in crop plants. https://phys.org/news/2024-11-barley-pangenome-reveals-diversity-domestication.html Molecular & Computational biology Wed, 13 Nov 2024 14:39:43 EST news650731179 Genomic detective work has brought researchers closer to the secret of how and why grass pea produces its notorious toxin, paving the way for this ancient and climate resilient crop to become a food of the future. https://phys.org/news/2023-07-toxic-climate-smart-crop-tomorrow.html Molecular & Computational biology Mon, 10 Jul 2023 10:41:04 EDT news608204461 The COVID-19 pandemic and the significant impact of emerging variants have shown the importance of understanding viruses in as much detail as possible. https://phys.org/news/2022-02-genomic-surveillance-rabies-outbreaks.html Plants & Animals Wed, 09 Feb 2022 09:26:40 EST news563621197 Missing metadata—data that provide information about other data—might not sound like a big deal, but it's a costly problem that's hindering humanity's plans to protect the planet's biodiversity. An international team of researchers has audited the largest global repository for storing genetic sequence data to see if the entries included basic metadata needed to make them useful for monitoring genetic diversity. They found that more than half of the datasets were missing that metadata. https://phys.org/news/2021-08-biodiversity-archiving.html Ecology Fri, 27 Aug 2021 09:12:09 EDT news549274325 Today, scientists can sift through quadrillions of genetic sequences in open-access databases, searching (free-of-charge) for new ways to engineer crops, develop medicines or even create synthetic organisms. But a controversial proposal that aims to share the benefits of digitized DNA could affect scientists' ability to use these data, according to an article in Chemical & Engineering News (C&EN). https://phys.org/news/2018-11-benefits-digitized-dna.html Other Wed, 28 Nov 2018 12:52:21 EST news462631931 Since 2011, a mysterious illness known as Yellow Canopy Syndrome, or YCS, has afflicted Australian sugarcane. The condition causes the mid-canopy leaves of otherwise healthy plants to rapidly turn yellow to a degree that the plant's sugar yield can decrease by up to 30 percent. https://phys.org/news/2017-08-tacc-supercomputers-uncover-genetic-roots.html Biotechnology Tue, 08 Aug 2017 15:48:04 EDT news421426076 The world's biggest genetic rice database is now available free online, a move scientists hope will contribute to a "green revolution", a leading rice research group said Wednesday. https://phys.org/news/2015-09-largest-genetic-rice-database-free.html Biotechnology Wed, 23 Sep 2015 12:17:54 EDT news362229462 Sequencing the DNA of an organism, whether human, plant, or jellyfish, has become a straightforward task, but assembling the information gathered into something coherent remains a massive data challenge. Researchers using computational resources at the San Diego Supercomputer Center (SDSC) at the University of California, San Diego, have created a faster and more effective way to assemble genomic information, while increasing https://phys.org/news/2013-09-scientists-tidal-genomic-sdsc-trestles.html Biotechnology Wed, 18 Sep 2013 16:25:56 EDT news298740345 When most people hear the word "graph," an image springs to mind: a pair of perpendicular lines overlaid with a line, a curve, or bars of different heights. https://phys.org/news/2012-12-graphs.html Computer Sciences Mon, 17 Dec 2012 07:17:19 EST news274951017 Using a new technique for cDNA preparation combined with the latest sequencing methods, researchers have uncovered the larval transcriptome of a reef-building coral (Acropora millepora). Their study, described in the open access journal BMC Genomics, features the most extensive database of genes and genetic markers currently available for any coral. https://phys.org/news/2009-05-genomic-technique-uncovers-transcriptome-reef-building.html Cell & Microbiology Tue, 12 May 2009 02:56:01 EDT news161315733
