The location of the atoms, groups or ions relative to one another in a molecule, as well as the number, type and location of covalent bonds.
The characteristic three-dimensional shape of a molecule.
Multicomponent ribonucleoprotein structures found in the CYTOPLASM of all cells, and in MITOCHONDRIA, and PLASTIDS. They function in PROTEIN BIOSYNTHESIS via GENETIC TRANSLATION.
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
Process of generating a genetic MUTATION. It may occur spontaneously or be induced by MUTAGENS.
An enzyme that catalyzes the hydrolysis of ADENOSINE to INOSINE with the elimination of AMMONIA.
Any of the processes by which cytoplasmic factors influence the differential control of gene action in viruses.
The level of protein structure in which regular hydrogen-bond interactions within contiguous stretches of polypeptide chain give rise to alpha helices, beta strands (which align to form beta sheets) or other types of coils. This is the first folding level of protein conformation.
Enzymes that catalyze the hydrolysis of the internal bonds and thereby the formation of polynucleotides or oligonucleotides from ribo- or deoxyribonucleotide chains. EC 3.1.-.
NMR spectroscopy on small- to medium-size biological macromolecules. This is often used for structural investigation of proteins and nucleic acids, and often involves more than one isotope.
A DNA-dependent DNA polymerase characterized in prokaryotes and may be present in higher organisms. It has both 3'-5' and 5'-3' exonuclease activity, but cannot use native double-stranded DNA as template-primer. It is not inhibited by sulfhydryl reagents and is active in both DNA synthesis and repair. EC
An essential amino acid that is required for the production of HISTAMINE.
Processes involved in the formation of TERTIARY PROTEIN STRUCTURE.
The sequential correspondence of nucleotides in one nucleic acid molecule with those of another nucleic acid molecule. Sequence homology is an indication of the genetic relatedness of different organisms and gene function.
The parts of a macromolecule that directly participate in its specific combination with another molecule.
The ability of microorganisms, especially bacteria, to resist or to become tolerant to chemotherapeutic agents, antimicrobial agents, or antibiotics. This resistance may be acquired through gene mutation or foreign DNA in transmissible plasmids (R FACTORS).
The genetic constitution of the individual, comprising the ALLELES present at each GENETIC LOCUS.
Sequential operating programs and data which instruct the functioning of a digital computer.
An enzyme that catalyzes the acetylation of chloramphenicol to yield chloramphenicol 3-acetate. Since chloramphenicol 3-acetate does not bind to bacterial ribosomes and is not an inhibitor of peptidyltransferase, the enzyme is responsible for the naturally occurring chloramphenicol resistance in bacteria. The enzyme, for which variants are known, is found in both gram-negative and gram-positive bacteria. EC
Techniques used to separate mixtures of substances based on differences in the relative affinities of the substances for mobile and stationary phases. A mobile phase (fluid or gas) passes through a column containing a stationary phase of porous solid or liquid coated on a solid support. Usage is both analytical for small amounts and preparative for bulk amounts.
Proteins found in ribosomes. They are believed to have a catalytic function in reconstituting biologically active ribosomal subunits.

DNA molecules capable of autonomous replication within a host cell and into which other DNA sequences can be inserted and thus amplified. Many are derived from PLASMIDS; BACTERIOPHAGES; or VIRUSES. They are used for transporting foreign genes into recipient cells. Genetic vectors possess a functional replicator site and contain GENETIC MARKERS to facilitate their selective recognition.
The outer protein protective shell of a virus, which protects the viral nucleic acid.

Spirochete and protist symbionts of a termite (Mastotermes electrodominicus) in Miocene amber. (1/41)

Extraordinary preservation in amber of the Miocene termite Mastotermes electrodominicus has led to the discovery of fossil symbiotic microbes. Spirochete bacteria and wood-digesting protists were identified in the intestinal tissue of the insect. Fossil wood (xylem: developing vessel-element cells, fibers, pit connections), protists (most likely xylophagic amitochondriates), an endospore (probably of the filamentous intestinal bacterium Arthromitus = Bacillus), and large spirochetes were seen in thin section by light and transmission electron microscopy. The intestinal microbiota of the living termite Mastotermes darwiniensis, a genus now restricted to northern Australia, markedly resembles that preserved in amber. This is a direct observation of a 20-million-year-old xylophagus termite fossil microbial community.  (+info)

Extinction and biogeography in the Caribbean: new evidence from a fossil riodinid butterfly in Dominican amber. (3/41)

We describe a new species of extinct riodinid butterfly, Voltinia dramba, from Oligo-Miocene Dominican amber (15-25 Myr ago). This appears to be the first butterfly to be taxonomically described from amber, and the first adult riodinid fossil. The series of five specimens represents probably the best-preserved fossil record for any lepidopteran. The phenomenon of extant Voltinia females ovipositing on arboreal epiphytes probably explains the discovery of multiple female V. dramba specimens in amber. Voltinia dramba appears to be one of many extinct butterfly species on Hispaniola. The northwestern Mexican distribution of the explicitly hypothesized sister species, the extant V. danforthi, supports the hypothesis that V. dramba reached Hispaniola by the 'proto-Greater Antillean arc', dating the divergence of V. dramba and V. danforthi to 40-50 Myr ago. This date is contemporaneous with the oldest known butterfly fossils, and implies a more ancient date of origin for many of the higher-level butterfly taxa than is often conceded.  (+info)

Ancient genes of Saccharomyces cerevisiae. (4/41)

Amber is a plant resin mainly produced by coniferous trees that, after entrapping a variety of living beings, was subjected to a process of fossilization until it turned into yellowish, translucent stones. It is also one of the best sources of ancient DNA on which to perform studies on evolution. Here a method for the sterilization of amber that allows reliable ancient DNA extraction with no actual DNA contamination is described. Working with insects taken from amber, it was possible to amplify the ATP9, PGU1 and rRNA18S ancient genes of Saccharomyces cerevisiae corresponding to samples from the Miocene and Oligocene. After comparison of the current genes with their ancient (up to 35-40 million years) counterparts it was concluded that essential genes such as rRNA18S are highly conserved and that even normal 'house-keeping' genes, such as PGU1, are strikingly conserved along the millions of years that S. cerevisiae has evolved.  (+info)

Cellular fine structures and histochemical reactions in the tissue of a cypress twig preserved in Baltic amber. (5/41)

A twig of a cypress plant preserved for ca. 45 Myr in Baltic amber was analysed by light and electron microscopy. Cross-sections of the whole plant showed an almost intact tissue of the entire stem and leaves, revealing, to our knowledge, the oldest and most highly preserved tissue from an amber inclusion reported so far. The preparations are based on a new technique of internal imbedding, whereby the hollow spaces within the inclusion are filled with synthetic resin which stabilizes the cellular structures during the sectioning procedure. Cytological stains applied to the sections reacted with cell walls and nuclei. A strong green auto-fluorescence of the cuticle and the resin canals in the leaves was observed. Transmission electron micrographs revealed highly preserved fine structures of cell walls, membranes and organelles. The results were compared with taxonomically related recent Glyptostrobus and Juniperus plants.  (+info)

First identifiable Mesozoic harvestman (Opiliones: Dyspnoi) from Cretaceous Burmese amber. (6/41)

Two inclusions in a piece of Upper Cretaceous (Albian) Burmese amber from Myanmar are described as a harvestman (Arachnida: Opiliones), Halitherses grimaldii new genus and species. The first Mesozoic harvestman to be named can be referred to the suborder Dyspnoi for the following reasons: prosoma divided into two regions, the posterior formed by the fusion of the meso- and metapeltidium; palp lacking a terminal claw, with clavate setae, and tarsus considerably shorter than the tibia. The bilobed, anteriorly projecting ocular tubercle is reminiscent of that of ortholasmatine nemastomatids. The status of other Mesozoic fossils referred to Opiliones is briefly reviewed.  (+info)

Early Cretaceous spider web with its prey. (7/41)

The orb web is a spectacular evolutionary innovation that enables spiders to catch flying prey. This elegant, geometric structure is woven with silk fibers that are renowned for their superior mechanical properties. We used silk gland expression libraries to address a long-standing controversy concerning the evolution of the orb-web architecture. Contrary to the view that the orb-web design evolved multiple times, we found that the distribution and phylogeny of silk proteins support a single, ancient origin of the orb web at least 136 million years ago. Furthermore, we substantially expanded the repository of silk sequences that can be used for the synthesis of high-performance biomaterials.  (+info)

Amber from western Amazonia reveals Neotropical diversity during the middle Miocene. (8/41)

Tertiary insects and arachnids have been virtually unknown from the vast western Amazonian basin. We report here the discovery of amber from this region containing a diverse fossil arthropod fauna (13 hexapod families and 3 arachnid species) and abundant microfossil inclusions (pollen, spores, algae, and cyanophyceae). This unique fossil assemblage, recovered from middle Miocene deposits of northeastern Peru, greatly increases the known diversity of Cenozoic tropical-equatorial arthropods and microorganisms and provides insights into the biogeography and evolutionary history of modern Neotropical biota. It also strengthens evidence for the presence of more modern, high-diversity tropical rainforest ecosystems during the middle Miocene in western Amazonia.  (+info)

Kimberlite is a type of potassic volcanic rock best known for sometimes containing diamonds. It is named after the town of Kimberley in South Africa, where the discovery of an 83.5-carat (16.7 g) diamond in 1871 spawned a diamond rush, eventually creating the Big Hole.. Kimberlite occurs in the Earths crust in vertical structures known as kimberlite pipes. Kimberlite pipes are the most important source of mined diamonds today. The consensus on kimberlites is that they are formed deep within the mantle. Formation occurs at depths between 150 and 450 kilometres (93 and 280 mi), from anomalously enriched exotic mantle compositions, and are erupted rapidly and violently, often with considerable carbon dioxide and other volatile components. It is this depth of melting and generation which makes kimberlites prone to hosting diamond xenocrysts.. Kimberlite has attracted more attention than its relative volume might suggest that it deserves. This is largely because it serves as a carrier of diamonds ...

Amber has been the subject of scientific studies which clearly indicate therapeutic properties. Amber is the fossilised resin from prehistoric trees with some dating as far back as 50 million years ago. The resin would have been used by the tree itself as a natural antibiotic or for preservation. For centuries it has been worn as a natural remedy for pain relief. When amber is worn on the skin, heat releases minuscule amounts of healing oils which are absorbed into the bloodstream. Scientific findings show that amber is electromagnet, producing significant amounts of organic, purely natural energy. ...

The cortices of pieces of Cretaceous amber around the world commonly are constituted by networks of filamentous structures. Based on their morphological characteristics, such structures have previously been classified in different microorganismal groups. Their correct interpretation, however, is of great importance to establish the conditions of the resins burial in the forest litter, and can provide important clues regarding the ecology and environmental conditions of Cretaceous resinous forests. Because these networks of filamentous structures present typical fungal morphological features we conducted a study in order to resolve their origin. The cortices of several pieces of Cretaceous amber from Spain were examined using light and scanning electron microscopy, energy dispersive X-ray spectroscopy, and confocal laser scanning microscopy. This is the first time that Calcofluor white and Wheat germ agglutinin conjugated with fluorescein isothiocyanate have been employed as fungal markers in ...

Nothing gets between a fiercely protective mother spider and her children. Dripping tree resin trapped adult female spiders and baby spiderlings about 99 million years ago, forever showcasing the maternal care exhibited by these arthropods, according to new research.. The Lagonomegopidae family of spiders is now extinct, but spiders have a long history and first appeared during the Carboniferous period between 359 to 299 million years ago.. The fossilized Burmese amber pieces tell two different stories. A study detailing the observations of the amber specimens published Tuesday in the journal Proceedings of the Royal Society B: Biological Sciences.. One shows a female lagonomegopid spider clutching an egg sac containing eggs about to hatch (you can see the little pre-hatchlings within the egg sac), said study author Paul Selden, the Gulf-Hedberg Distinguished Professor Emeritus at the University of Kansas, in an email. This is exactly how a living female spider which is nestled in a crevice ...
The fossilized Burmese amber pieces tell two different stories. A study detailing the observations of the amber specimens published Tuesday in the journal Proceedings of the Royal Society B: Biological Sciences.. One shows a female lagonomegopid spider clutching an egg sac containing eggs about to hatch (you can see the little pre-hatchlings within the egg sac), said study author Paul Selden, the Gulf-Hedberg Distinguished Professor Emeritus at the University of Kansas, in an email. This is exactly how a living female spider which is nestled in a crevice in tree bark would look (in this case, right before being swamped with tree resin).. Other pieces of amber show a group of tiny spiderlings that had just hatched. This shows that a female lagonomegopid spider guarded her egg sac from harm. Once the spiderlings hatched, they stayed together and were guarded by their mother - as evidenced by the Lagonomegopidae leg fragments from the same piece of amber.. This suggests that baby spiderlings ...
Presented is the first absolute age for the basal Albian from the Schwicheldt Ton Member, Gault Formation, Vöhrum, Germany. A 206Pb/238U age of 113.1 ± 0.3 Ma is determined for chemically abraded zircon from a tuff horizon 65 cm above the Aptian/Albian boundary. The new U-Pb age, although within uncertainty of the GTS 2008 determination (112 ± 1 Ma), is nominally older. The younger GTS 2008 basal Albian age is obtained from cyclostratigraphy using an 40Ar-39Ar age from the base Cenomanian. The nominal difference between the GTS 2008 age and new basal Albian age is consistent with the documented ca. 0.65% bias between U-Pb and 40Ar/39Ar geochronology. The new 206Pb/238U age calls into question a recently published age for the basal Albian (106.9 ± 0.4 Ma) determined from K-Ar glauconite analysis, as well as the K-Ar age for the GL-O international standard.

July 19, 2017 - A 9-year-old boy walking through the New Mexico desert stumbled upon an extremely rare find-a million-year-old Stegomastodon fossil. While hiking with his family, the boy literally tripped over the fossil as it protruded from the ground. Stegomastodons were ancient tusked mammals, distant cousins to mammoths and modern elephants. They lived an estimated 1.2 million years ago. Only a couple hundred Stegomastodon fossils have been discovered in the world. The fossil was eventually excavated and brought to a museum.Click here to read Boy Found Million-Year-Old Fossil by Tripping Over It.

The oldest named fossil tabanid is a species of Tabanus from the Eocene/ Oligocene deposits of the Isle of Wight described by Cockerell (1921c). The species of Haematopota described by Stuckenberg (1975) as from Baltic amber has been shown by Lewis et al. (1977) to actually be a copal inclusion from an unknown locality in Africa. An older undetermined compression fossil of Tabanidae from the Middle Jurassic Mont-Saint-Marin deposit in Luxemburg was noted by Maurice (1882). There are Cretaceous genera described by Kovalev (1986) from Mongolia, but are treated in this catalog as unplaced in Tabanoidea ...

Daza 1 and Aaron M. Bauer 1 - 2 Abstract. A new species of Sphaerodactylus (Squamata: Gekkota: Sphaerodactylidae) is described from an amber inclusion from the late Early Miocene or early Middle Miocene (15 to 20 million years ago) of the Dominican Republic. Unlike earlier amber-embedded specimens assigned to this genus, the new specimen is largely skeletal, with some integument remaining. A combination of 258 (of 674) osteological and external characters could be scored for the new species in a cladistic analysis of 21 gekkotan species, including representatives of all sphaerodactylid genera. The most parsimonious trees obtained confirm the placement of the amber gecko within the genus Sphaerodactylus and a comparison with extant ...

Three issues immediately put Dominican Republic brides forward of various mail order brides. Eventually Anna educated Mursel that she cant marry him if his household doesnt find out about her children. Dominican girls are very critical about their traditions and would acknowledge it should you had the equal ranges of respect as them. Their tradition could be very numerous and is stuffed with newer options which could probably be very totally different from the Western one.. One of those components is the Dominican mail order brides wish to have totally different lives and relationships. Informal unions are common in the Dominican Republic, whereby girls and adolescents transfer into the homes of grownup males and switch into their wives. The most generally spoken language in the Dominican Republic is Spanish, however the wonderful news is that it wont make your relationship more difficult. There is a big chance that you already know a bit of Spanish from school and your Dominican bride is ...

In the Colonial Zone on July 8, 2001 the Association of Spanish Festivities in Dominican Republic held the islands first bull run, a version of Spains San Fermin bull run. A three-minute bull run took place from Calle Atarazana, through Vicente Celestino Duarte to Cristobal Colon. Youths raced and the poor, confused bulls had no idea what was happening. It seems that the Dominican bulls were just too lazy, resulting in them having to be pushed through the streets, instead of them chasing the participants.. *Did you know that there was a small town in Dominican Republic where it was discovered and documented in the early 1970s that girls turned into boys? It seems that children appearing to be girls turned into men at puberty. First girls when they reached puberty they grew testes, and a penis. They called these children guevedoces which literally means penis at 12 years. Also known locally as machihembras (first women, then man). It was published in the American Journal of Medicine.

This is not an Earwig, but it does remind us of a very unusual beetle we have in our archive, the Ship-Timber Beetle. We have a representative that was photographed in Costa Rica and it has been identified as being in the family Lymexylidae and the genus Atractocerus. We will need to do additional research to see if the Ship-Timber Beetles are known to be found in Africa. This posting from Beetles in the Bush makes our identification likely correct. According to Beetles in the Bush: Atractocerus species are rarely encountered and therefore, not well studied. Their evolutionary history is still unknown; however, the oldest known lymexylid fossil is a very primitive member of the genus Atractocerus preserved in 100 myo Burmese amber (Grimwold & Engel 2005). Thus, the lineage containing these beetles had already appeared by the mid-Cretaceous and may have originated as early as the Jurassic, a fact that has earned them the moniker living fossils. These beetles were once thought to be among the ...

The Dominican Republic has enjoyed strong GDP growth since 2005, and continued to post sound gains through mid-2008. The global recession, however, had a significant impact on GDP growth in the latter half of the year as tourism and remittances, two of the Dominican Republics most important economic contributors, showed signs of slowing. The economy is highly dependent upon the US, the source of nearly three-fourths of exports, and remittances represent about a tenth of GDP, equivalent to almost half of exports and three-quarters of tourism receipts. The country has long been viewed primarily as an exporter of sugar, coffee, and tobacco, but in recent years the service sector has overtaken agriculture as the economys largest employer due to growth in tourism and free trade zones. Although 2007 saw inflation rates averaging around 6%, inflation rates in 2008 grew to over 11% on average for the first 3 quarters.

The nearly complete and remarkably preserved skeleton of a small, 47 million-year-old creature found in Germany was displayed Tuesday by scientists who said it would help illuminate the evolutionary roots of monkeys, apes and humans. Experts praised the discovery for the level of detail it provided but said it was far from a breakthrough that would solve the puzzles of early evolution. Nobody is claiming that its a direct ancestor of monkeys and humans, but it provides a good indication of what a long-ago ancestor may have looked like, researchers said at a news conference. The fossil is the best preserved ever found for a primate, said Jorn Hurum, of the University of Oslo Natural History Museum, one of the scientists introducing the specimen. Beard said scientists already have a fossil from China of about the same age that is widely accepted as coming from monkey-ape-human ancestral line, and its much smaller than the new-found fossil and ate a different diet.
An exquisitely preserved fossil found in China still contains the original biological compounds that gave a 130-million-year-old bird its shading and colour.
A missing link in the evolution of the front claw of living scorpions and horseshoe crabs was identified with the discovery of a 390-million-year-old fossil by researchers at Yale and the University of Bonn, Germany.
Researchers have retrieved original pigment, beta-keratin and muscle proteins from a 54-million-year-old sea turtle hatchling. The work adds to the growing body of evidence supporting persistence of original molecules over millions of years and also provides direct evidence that a pigment-based survival trait common to modern sea turtles evolved at least 54 million years ago. 17th October 2017 01:18 PM More...

Oswald Syme retired in 1964 and his grandson Ranald Macdonald was appointed managing director at the age of 26 and Two years later he appointed Graham Perkin as editor. in order to ensure that the 36-year-old Perkin was free of board influence, Macdonald took on the role of editor-in-chief, a position he held until 1970. Together they radically changed the paper's format and shifted its editorial line from rather conservative liberalism to a new "left liberalism" characterised by attention to issues such as race, gender, the disabled and the environment, as well as opposition to White Australia and the death penalty. It also became more supportive of the Australian Labor Party after years of having usually supported the Coalition. The Liberal Premier of Victoria, Henry Bolte, subsequently called The Age "that pinko rag" in a view conservatives have maintained ever since.

  • Especially rich beds of amber in Lebanon and New Jersey have yielded many Cretaceous species dating back as much as 135 million years. (
  • But according to a report published today in the Proceedings of the National Academy of Sciences, a fossil worker ant preserved in New Jersey amber from deposits dating back some 90 million years ago to the Cretaceous period suggests that ant diversification began earlier and proceeded more rapidly than previously thought. (
  • We can only hope that this cycle of discovery and revision will continue or even accelerate so that our current, clouded picture of ant phylogeny will come increasingly into focus, in much the same way, perhaps, that the initially vague but evocative form of a Cretaceous ant becomes progressively clearer when a nugget of amber is painstakingly prepared and polished by [David] Grimaldi and colleagues. (

  • Liquid amber trees do, however, have a fragrant resin that is routinely used in perfumes and incense. (
  • The oldest known fossils of arthropods (see Arthropoda ) are entombed in amber that dates from the Triassic period (230 million years ago). (
  • The ammonite also provides supporting evidence for the age of the amber, which is still debated, and represents a rare example of dating using fossils present inside the amber. (
  • Because this geologic unit lacks index fossils ( 12 , 13 ), we used independent age-relevant information from the amber itself, its inclusions, and the sporomorphs of the amber-bearing layer to date the amber. (
  • Not even fossils, but trapped in amber! (
  • The amber ant fossils also froze a number of eusocial behaviors in time. (
  • The 99-million-year-old frogs come from the same amber deposits in northern Myanmar that have produced many exquisite fossils, including a dinosaur tail , a couple of baby birds , intact bird wings, and countless insects . (

  • The fictitious world of Amber comes from Roger Zelazny 's "Amber" series of fantasy novels. (
  • Baltic amber also contains succinic acid and is often called succinite. (
