The attack left Ms Piper partially blinded, with severe and permanent scarring to her face, chest, neck, arm and hands. I will continue to need operations and therapy for life. In March , Danny Lynch, a man she had been dating, arranged for an accomplice to throw sulphuric acid in Ms Piper’s face. In her open letter, Ms Piper pictured shortly after the attack talks about how she contemplated suicide and how fearful survivors are She has since found love with James Sutton, who she married in and with whom she has a daughter, Belle Elizabeth. Ms Piper, has set up a charity to help hundreds of burn victims. Helped by Simon Cowell as well as the doctor who gave her her face back, the Katie Piper Foundation offers medical treatment and support.
Looy is one of many scientists trying to identify the killer responsible for the largest of the many mass extinctions that have struck the planet. The most famous die-off ended the reign of the dinosaurs 65 million years ago between the Cretaceous and Tertiary periods. Most researchers consider that case closed. Rocks of that age contain traces of an asteroid that struck Earth, generating catastrophic events from global wildfires to climate change.
But the Permian detectives are faced with a host of suspects and not enough evidence to convict any of them. To understand this extinction, I wanted first to get a sense of its scale.

Amino acid racemization dating of quaternary deposits of central and Southern Italy Author links open overlay panel GiorgioBelluomini LaurettaDelitala Show more https: Racemization dating proved to be a very useful tool to date non-marine and marine deposits which are a few hundred thousand years old, as well as to correlate and chronologically classify even more ancient marine deposits.
Aspartic acid racemization was used to date samples aged less than 80, — , yr; for more ancient samples, isoleucine epimerization, instead, was resorted to. In this work, dates were established for some important fragments of human bones and of large-mammalian fauna weighing a few grams, which would have been impossible to date with the 14C technique, requiring a large amount of bone material. The extent of isoleucine epimerization was measured in Glycymeris genera to estimate the age of numerous marine deposits of the Tyrrhenian coast of Centra-Southern Italy and of Sardinia.
In the Tarquinia area Latium three marine terraces were identified, which were estimated to be approx. In Sardinia, five marine horizons were identified; the youngest deposit Neotyrrhenian proved to be present at Punta tramontana and Santa Reparata, while, at Riola and Stagno di Sassu, the most ancient marine deposits of Sardinia were found.
Finally, from the terraced coastal deposits of Capo Milaazzo Sicily , Panarea Eolian archipelago , Archi Calabria and Gallipoli Apulia , a Tyrrhenian age range of , — , yr was obtained. Previous article in issue.

Dating methods Dating techniques are procedures used by scientists to determine the age of a specimen. Relative dating methods tell only if one sample is older or younger than another sample; absolute dating methods provide a date in years. The latter have generally been available only since Many absolute dating techniques take advantage of radioactive decay , whereby a radioactive form of an element is converted into another radioactive isotope or non-radioactive product at a regular rate.
Others, such as amino acid racimization and cation-ratio dating, are based on chemical changes in the organic or inorganic composition of a sample.

Chirality[ edit ] An object is said to have chirality if it is not possible to make it into a mirror-image of itself by turning it round. For example, a shoe is chiral: On the other hand, an object such as a table-knife is not chiral: Some molecules are chiral. For example, consider the two molecules in the picture to the right. They both have exactly the same chemical formula, but one is left-handed, and the other is right-handed. They are said to be enantiomers of one another. When we make chiral molecules using ordinary chemical processes, we usually produce equal quantities of both enantiomers.
Such a mixture is said to be racemic. However, biological processes produce molecules with a distinct chirality:

Special Sections Lysine Lysine is an essential amino acid that is well known for its antiviral properties. It helps prevent outbreaks of herpes and cold sores, and is needed for hormone production and the growth and maintenance of bones in both children and adults. Lysine is involved in the production off antibodies for a strong, healthy immune system, which may be part of the reason it is so effective at fighting herpes viruses.
Results of a six-month trial involving more than 50 people indicate that lysine is far more effective than a placebo in preventing cold sores. Lysine supplements have also been used to prevent eruptions of shingles, a blistering condition that is caused by the herpes varicella-zoster.

Enraged during one fight, Wallace had poured boiling water on him. He wanted out of the relationship, he told Wallace. In all, she looked at 82 websites about the corrosive substance, prosecutors said. Some of the sites showed bodies scarred black by the acid. She bought a bottle from Amazon. About a month after he announced that he was dating again, Wallace lured her ex to her home under the guise of rekindling their relationship.
The breakup had been an on-again off-again roller coaster, and van Dongen wanted to reiterate that he was moving on with his new girlfriend. But he ended up staying the night anyway.

Temperature and humidity histories of microenvironments are being produced at ever increasing rates as technologies advance and technologists accumulate data. These are important for amino acid dating because racemization occurs much faster in warm, wet conditions compared to cold, dry conditions. Temperate to cold region studies are much more common than tropical studies, and the steady cold of the ocean floor or the dry interior of bones and shells have contributed most to the accumulation of racemization dating data.
Generally, they are not assumed to have a great impact in the natural environment, though tephrochronological data may shed new light on this variable. The enclosing matrix is probably the most difficult variable in amino acid dating. This includes racemization rate variation among species and organs, and is affected by the depth of decomposition, porosity, and catalytic effects of local metals and minerals.
This amino acid ratio has the advantages of being relatively easy to measure and being chronologically useful through the Quaternary. Archeology ,  stratigraphy , oceanography , paleogeography , paleobiology , and paleoclimatology have been particularly affected. Their applications include dating correlation, relative dating, sedimentation rate analysis, sediment transport studies,  conservation paleobiology,  taphonomy and time-averaging,    sea level determinations, and thermal history reconstructions.

Every fourth Thursday of November, friends and family in the U. Those early revelers were probably knocked out by their marathon feast, and most people today are familiar with the post-Thanksgiving food coma. But often the blame falls on the bird. Turkey allegedly causes drowsiness because it is packed with a nutrient called tryptophan. Tryptophan is one of 20 naturally occurring amino acids—the building blocks of proteins.
Because the body is unable to manufacture tryptophan on its own, it must be obtained from food protein. Turkey is a great source of this essential acid, but it is not unique: Tryptophan is used by the human body to make serotonin, a neurotransmitter. It has a somnolent effect on fruit flies, whose sleep is most likely equivalent to our slow-wave non-REM sleep, says neuroscientist Amita Sehgal of the University of Pennsylvania School of Medicine in Philadelphia. Other studies show that one function of serotonin is the promotion of slow-wave sleep in nonhuman mammals, she adds, and it may do the same for humans.
Thus, it is no wonder that turkey, which provides the raw material for the synthesis of sleep-related serotonin, is purported to have soporific power. But eating turkey does not translate to amplified serotonin production in the brain, says neuropharmacologist Richard Wurtman of the Massachusetts Institute of Technology’s Department of Brain and Cognitive Sciences in Cambridge, Mass.

Etymology[ edit ] Hydrochloric acid was known to European alchemists as spirits of salt or acidum salis salt acid. Both names are still used, especially in other languages, such as German: Gaseous HCl was called marine acid air. The old pre- systematic name muriatic acid has the same origin muriatic means “pertaining to brine or salt”, hence muriate means hydrochloride , and this name is still sometimes used. Joseph Priestley of Leeds, England prepared pure hydrogen chloride in ,  and by Humphry Davy of Penzance, England had proved that the chemical composition included hydrogen and chlorine.
A new industrial process developed by Nicolas Leblanc of Issoundun, France enabled cheap large-scale production of sodium carbonate soda ash. In this Leblanc process , common salt is converted to soda ash, using sulfuric acid, limestone, and coal, releasing hydrogen chloride as a by-product. Until the British Alkali Act and similar legislation in other countries, the excess HCl was vented into the air.
After the passage of the act, soda ash producers were obliged to absorb the waste gas in water, producing hydrochloric acid on an industrial scale.
