Sedimentological And Stratigraphical Analysis Of Kaki Bukit Formation (Lower Setul Member) At Teluk Ewa, Pulau Langkawi

The identification of new units on the carbonate sequence of Teluk Ewa (from Tg. Mendidih to Teluk Ewa) has given an idea for the review of stratigraphic succession of Kaki Bukit Formation (Lower Setul Member). The analysis is related to a sedimentology study, where the sedimentary sequences formed as a mixed siliciclastic–carbonate shallow marine system that combines the carbonate and silisiclastic deposits. Eight facies have been recognised such as (1) argillite facies, (2) interlayer of mudstone and limestone facies, (3) wavy stromatolites limestone facies, (4) linear stromatolites limestone facies, (5) heterolithic of mudstone-limestone facies, (6) shale facies, (7) massive limestone facies and (8) thrombolites limestone facies. Each facies are divided into four litostratigraphic units based on the evaluation from Malaysian Stratigraphic Nomenclature Committee (1997) and North American Stratigraphic Code 2005. (1) The clastic unit referring to the uppertmost part of Machinchang Formation maintains it's name. Meanwhile, the suggested nomenclature for the new units such as (2) The Sabung Member is referring to the basal carbonate unit comprising microbial facies and mixed silisiclastic-carbonate sediment. (3) The Pesak Seluar Member in the middle is a silisiclastic unit that consists of shale facies and (4) The Ewa Member at the top representing the upper limestone unit. All units show a similar litostratigraphic characteristics that are found in Tarutao Group, Pante Malaka Formation, Rung Nok Formation and Lae Tong Formation in Thailand as described by Wongwanich et al. (1990; 2002) and Imsamut & Abdul Rahman (2017).

HUGO Gene Nomenclature Committee (HGNC) recommendations for the designation of gene fusions

Gene fusions have been discussed in the scientific literature since they were first detected in cancer cells in the early 1980s. There is currently no standardized way to denote the genes involved in fusions, but in the majority of publications the gene symbols in question are listed either separated by a hyphen (-) or by a forward slash (/). Both types of designation suffer from important shortcomings. HGNC has worked with the scientific community to determine a new, instantly recognizable and unique separator—a double colon (::)—to be used in the description of fusion genes, and advocates its usage in all databases and articles describing gene fusions.

The Moroccan experience on Meteoritics and Planetary Science

<p>Morocco is a treasure house of meteorites, most meteorites accessible to scientists and collectors in all over the world are originated from Morocco and surrounding countries. Collection of meteorites is essentially done in hot and cold deserts. Morocco has a large and safe Sahara where many nomads are living. A big community of meteorite hunters is well established. Nomads and hunters are good observers, they learned by practicing how to make the difference between terrestrial and extra-terrestrial rocks that represent an important source of revenue for them. Those meteorites are almost all exported. All classes of meteorites are found in the hot deserts including many rare and important for scientific research ones.</p> <p>Since 2001, our team in the Hassan II University of Casablanca Faculty of Science Ain Chock is working on the promotion of meteorites in Morocco, Arab countries and Africa. Cosmochemistry courses has been introduced to the national curricula. Many PhD thesis has been prepared and defended. Since 2004 meteorite falls in Morocco have been classified and submitted to the Nomenclature Committee of the Meteoritical Society by our team, including the exceptional fifth Martian meteorite fall in Morocco “Tissint”. Many valuable papers have been published on these falls.</p> <p>On 2019, ATTARIK Foundation for Meteoritics and Planetary Science was created by our team and a group of passionate people. The aim of ATTARIK is to support the research of the PhD students on Planetary Sciences and to disseminate sciences through youth in cities and countryside. The Africa Initiative for Planetary and Space Science was launched on 2016 in Cape Town has similar objectives.</p> <p>The Moroccan experience can be a good reference to development of planetary sciences in Africa and the Arab countries.</p>

Genenames.org: the HGNC and VGNC resources in 2021

The HUGO Gene Nomenclature Committee (HGNC) based at EMBL’s European Bioinformatics Institute (EMBL-EBI) assigns unique symbols and names to human genes. There are over 42,000 approved gene symbols in our current database of which over 19 000 are for protein-coding genes. While we still update placeholder and problematic symbols, we are working towards stabilizing symbols where possible; over 2000 symbols for disease associated genes are now marked as stable in our symbol reports. All of our data is available at the HGNC website https://www.genenames.org. The Vertebrate Gene Nomenclature Committee (VGNC) was established to assign standardized nomenclature in line with human for vertebrate species lacking their own nomenclature committee. In addition to the previous VGNC core species of chimpanzee, cow, horse and dog, we now name genes in cat, macaque and pig. Gene groups have been added to VGNC and currently include two complex families: olfactory receptors (ORs) and cytochrome P450s (CYPs). In collaboration with specialists we have also named CYPs in species beyond our core set. All VGNC data is available at https://vertebrate.genenames.org/. This article provides an overview of our online data and resources, focusing on updates over the last two years.
