The latest observations combined data from Chandra and ESA’s XMM-Newton space observatory and radio data from the Murchison Widefield Array (MWA) in Australia and the Giant Metrewave Radio Telescope (GMRT) in India to provide compelling new evidence for the gigantic explosion. Over the years, astronomers have proposed a number of different properties for the dust grains and so Andrea and colleagues were able to test them against the X-ray data. They found that one model reproduced the rings extremely well. In this model, the dust grains were composed mostly of graphite, a crystalline form of carbon. They also used their data to reconstruct the X-ray emission from the GRB itself because that particular signal was not observed directly by any instrument.

The torpedo also factors into one of the event’s biggest surprises. Fermi’s main instrument, the Large Area Telescope (LAT), also detected three gamma rays, with energies of 480 MeV, 1.3 billion electron volts (GeV), and 1.7 GeV – the highest-energy light ever detected from a magnetar giant flare. What’s surprising is that all of these gamma rays appeared long after the flare had diminished in other instruments. The light following the burst, called the afterglow emission, also exhibited unusual features. Fermi detected high-energy gamma rays starting 1.5 hours post-burst and lasting more than 2 hours. These gamma rays reached energies of up to 1 billion electron volts. (Visible light’s energy measures between about 2 and 3 electron volts, for comparison.) Things that people think of as energetic, like supernova, are nowhere near energetic enough for this,” said Matthews. “You need huge amounts of energy, really high magnetic fields, to confine the particle while it gets accelerated.” Giant flares within our galaxy are so brilliant that they overwhelm our instruments, leaving them to hang onto their secrets,” Roberts said. “For the first time, GRB 200415A and distant flares like it allow our instruments to capture every feature and explore these powerful eruptions in unparalleled depth.” Being much further away, around two billion light-years instead of several tens of thousands, meant that the GRB had to be exceptionally bright.Camacho C, Coulouris G, Avagyan V, Ma N, Papadopoulos J, Bealer K, et al. BLAST+: architecture and applications. BMC Bioinformatics. 2009;10:421–9. The IPN placed the April 15 burst, called GRB 200415A, squarely in the central region of NGC 253, a bright spiral galaxy located about 11.4 million light-years away in the constellation Sculptor. This is the most precise sky position yet determined for a magnetar located beyond the Large Magellanic Cloud, a satellite of our galaxy and host to a giant flare in 1979, the first ever detected. Identification and analysis of gene clusters is an important task in synthetic biology [ 26, 27]. Unfortunately, identifying candidate gene clusters is complex and can take hours for a single genome. However, with prior knowledge about the expected genes in a cluster, the genome can be screened in a way that limits the search space dramatically. Run the blastx (or blastn) wrapper using the gene(s) of interest as the query against the new database.

The expansion of the Galaxy wrappers for BLAST+ has followed a similar course. The initial wrappers focused on the five core tools (BLASTP, BLASTN, BLASTX, TBLASTN and TBLASTX) and did not allow the creation of custom BLAST databases. Gradually, the scope and contributor base of the project has expanded (Tables 1 and 3), particularly since our publication of genome and protein annotation tools [ 10], and was also supported by the move to a dedicated source code repository on GitHub. This shift to a distributed international team effort followed discussions, both online and in person at the Galaxy Community Conference 2013, and reflects the broad usage of the BLAST+ tools within the Galaxy community.

Ubertini said the disturbance that occurred in the ionosphere was not seen by anyone on the ground.Plant pests and pathogens introduce effector proteins into the host plant cell (green), where they can target and manipulate plant biochemistry to the benefit of the pathogen ( Dodds & Rathjen, 2010). Effectors may be delivered by haustorial ingression from a fungus or oomycete such as P. infestans (orange), via the bacterial Type III secretion system mechanism (blue), by nematodes via injection into the plant cell though a needle-like stylet (red), or many other processes (not illustrated). Where effectors may be identified by sequence properties, candidate effector proteins can be computationally predicted using Galaxy. One of the core concepts in Galaxy is that each dataset has a specified datatype or file format, such as FASTA format sequences or various FASTQ encodings [ 32]. Each Galaxy tool normally accepts only specific datatypes as input and will mark its output files with the appropriate datatype. We defined a set of datatypes for BLAST ASN.1 files, BLAST XML and the different BLAST database types (see Table 3). Simple datatypes can be defined by subclassing already existing datatypes. In general, additional Python code is required, such as defining a sniff function for auto-detection of the datatype when loading files into Galaxy. Another popular tool for initial functional annotation of novel gene sequences is Blast2GO ( Conesa et al., 2005; Götz et al., 2008) which, in addition to its Graphical User Interface (GUI), offers a command line variant b2g4pipe (Blast2GO for pipelines) which we have wrapped for use in Galaxy. We implement whole organism scale Blast2GO in Galaxy as a simple two step pipeline, as used in Palomares-Rius et al. (2012), taking advantage of a local computing cluster: A team led by Benjamin Gompertz, an astrophysicist at the University of Birmingham in the United Kingdom, looked at the entire high-energy light curve, or the evolution of the event’s brightness over time. The scientists noted features that might provide a key for identifying similar incidents – long bursts from mergers – in the future, even ones that are dimmer or more distant. The more astronomers can find, the more they can refine their understanding of this new class of phenomena.

The Galaxy-P project (Minnesota Supercomputing Institute, University of Minnesota) contributed extensions to Galaxy known as tool macros that make it considerably easier to develop and maintain large suites of Galaxy tools by allowing authors to define high-level abstractions describing any aspect of Galaxy’s XML-based tool description language. These abstractions can be combined and shared across various tools in a suite. In wrapping the NCBI+ BLAST tool suite we have made heavy use of macros to avoid the duplication of common parameters, command line arguments and even help text. In addition to removing hundreds of lines of XML, this approach helps with consistency and maintenance, as many changes need only be made once to the macro definition.

On Dec. 11, 2021, NASA’s Neil Gehrels Swift Observatory and Fermi Gamma-ray Space Telescope detected a blast of high-energy light from the outskirts of a galaxy around 1 billion light-years away. The event has rattled scientists’ understanding of gamma-ray bursts (GRBs), the most powerful events in the universe.This simple protocol does not consider complications such as frame-shifts due to sequencing or assembly errors, but represents a simple initial framework to begin such an analysis. Galaxy Tool Shed Repository “Filter sequences by ID”: https://toolshed.g2.bx.psu.edu/view/peterjc/seq_filter_by_id/ Complex tools with a large number of options present a particular challenge to wrapper design, when attempting to balance the desire to offer full control and flexibility against usability. In the case of the NCBI BLAST+ tools, we chose initially to omit some of the less commonly-used options, and to provide others in an ‘advanced options’ section. Similarly, the wrapper for the MIRA assembler ( Chevreux, Wetter & Suhai, 1999) currently exposes only the most common arguments as user-configurable parameters.

This has always been regarded as a possibility, and several GRBs observed since 2005 have provided tantalizing evidence,” said Kevin Hurley, a Senior Space Fellow with the Space Sciences Laboratory at the University of California, Berkeley, who joined several scientists to discuss the burst at the virtual 237th meeting of the American Astronomical Society. “The April 15 event is a game changer because we found that the burst almost certainly lies within the disk of the nearby galaxy NGC 253.” A classic short gamma-ray burst begins with two orbiting neutron stars, the crushed remnants of massive stars that exploded as supernovae. As the stars circle ever closer, they strip neutron-rich material from each other. They also generate gravitational waves, or ripples in space-time – although none were detected from this event.Run a fast assembler such as the CLC Assembly Cell (CLC bio, Aarhus, Denmark) which we have wrapped for use within Galaxy to generate an initial set of contigs [ 21]. This power is yet to receive an official name, but most One Piece fans conventionally call it the "Advanced Conqueror's Haki."
