Ancient Egyptians accessorized with meteorites

2013-05-30
(Press-News.org) Researchers at The Open University (OU) and The University of Manchester have found conclusive proof that Ancient Egyptians used meteorites to make symbolic accessories.

The evidence comes from strings of iron beads which were excavated in 1911 at the Gerzeh cemetery, a burial site approximately 70km south of Cairo. Dating from 3350 to 3600BC, thousands of years before Egypt's Iron Age, the bead analysed was originally assumed to be from a meteorite owing to its composition of nickel-rich iron. But this hypothesis was challenged in the 1980s when academics proposed that much of the early worldwide examples of iron use originally thought to be of meteorite-origin were actually early smelting attempts.

Subsequently, the Gerzeh bead, still the earliest discovered use of iron by the Egyptians, was loaned by the Manchester Museum to the OU and the University of Manchester's School of Materials for further testing. Researchers used a combination of the OU's electron microscope and Manchester's X-Ray CT scanner to demonstrate that the nickel-rich chemical composition of the bead confirms its meteorite origins.

OU Project Officer Diane Johnson, who led the study, said: "This research highlights the application of modern technology to ancient materials not only to understand meteorites better but also to help us understand what ancient cultures considered these materials to be and the importance they placed upon them."

Meteorite iron had profound implications for the Ancient Egyptians, both in their perception of the iron in the context of its celestial origin and in early metallurgy attempts.

Co-author Dr Joyce Tyldesley, a Senior Lecturer in Egyptology at The University of Manchester, said: "Today, we see iron first and foremost as a practical, rather dull metal. To the ancient Egyptians, however, it was a rare and beautiful material which, as it fell from the sky, surely had some magical/religious properties. They therefore used this remarkable metal to create small objects of beauty and religious significance which were so important to them that they chose to include them in their graves."

Philip Withers, Professor of Materials Science at The University of Manchester, added: "Meteorites have a unique microstructural and chemical fingerprint because they cooled incredibly slowly as they travelled through space. It was really interesting to find that fingerprint turn up in Egyptian artefacts."

Worldwide, over 15,000 species are threatened by extinction, and the loggerhead sea turtle is no exception. Once the mysteries surrounding some of the species behavior are resolved, more effective conservation programs can be developed to facilitate their protection. The case of the loggerhead sea turtle is particularly interesting: Why do they migrate for several thousands of kilometers to eventually come back to their place of birth for reproduction after roughly 25 years? To address this question, a group of evolutionary biologists from GEOMAR Helmholtz Centre for ...

Report shows billions worldwide suffer from major tooth decay

2013-05-30
Billions of people across the globe are suffering from major untreated dental problems, according to a new report led by Professor Wagner Marcenes of Queen Mary, University of London, published in the Journal of Dental Research. Professor Marcenes of the Institute of Dentistry at Queen Mary led an international research team investigating oral health as part of the Global Burden of Disease (GBD) 2010 study. The report shows that oral conditions affect as many as 3.9bn people worldwide – over half the total population. Untreated tooth decay or cavities in permanent teeth ...

Mystery solved: Why people on dialysis have increased risk of heart attack

2013-05-30
Bethesda, MD—Patients with advanced kidney disease who are undergoing hemodialysis are known to be highly susceptible to heart attacks and other cardiovascular complications, and now scientists likely know why. New research findings published in the Journal of Leukocyte Biology show that uremic toxins, which are not removed by hemodialysis, increase heart attack risk. The same scientists also have found what can reduce this risk: an oral adsorbent called "AST-120." "Treatment with AST-120, an oral adsorbent, will not only delay the progression of kidney disease, ...

A newly discovered hormone makes ovaries grow

2013-05-30
Bethesda, MD—A newly discovered hormone produced by the eggs of human females may improve the effectiveness of current fertility treatments for women and possibly lead to entirely new treatments altogether. According to new research published in the June 2013 issue of The FASEB Journal, researchers from Stanford and Akira University in Japan identified a new hormone called "R-spondin2" that promotes follicle development and stimulates ovary growth. "The finding of a new ovarian hormone produced by the oocytes capable of stimulating ovarian follicle growth could lead ...

Immune system to fight brain tumors

2013-05-30
Research at Lund University in Sweden gives hope that one of the most serious types of brain tumour, glioblastoma multiforme, could be fought by the patients' own immune system. The tumours are difficult to remove with surgery because the tumour cells grow into the surrounding healthy brain tissue. A patient with the disease therefore does not usually survive much longer than a year after the discovery of the tumour. The team has tested different ways of stimulating the immune system, suppressed by the tumour, with a 'vaccine'. The vaccine is based on tumour cells that ...

New discovery permits rapid diagnosis and treatment of sepsis

2013-05-30
Bethesda, MD—Despite numerous advances in treating infections and disease, effective treatments for sepsis remain elusive. A new discovery published in the June 2013 issue of The FASEB Journal not only could help health care providers predict who is more and less likely to develop sepsis, but it also opens the doors to new therapies that actually address the root cause of the problem, rather than just managing the symptoms. This also has the potential to benefit patients suffering from influenza and other viral infections, as well as chronic inflammatory diseases such ...

New gene delivery method: magnetic nanoparticles

2013-05-30
Bethesda, MD—Stent angioplasty saves lives, but there often are side effects and complications related to the procedure, such as arterial restenosis and thrombosis. In the June 2013 issue of The FASEB Journal, however, scientists report that they have discovered a new nanoparticle gene delivery method that may overcome current limitations of gene therapy vectors and prevent complications associated with the stenting procedure. Specifically, this strategy uses stents as a platform for magnetically targeted gene delivery, where genes are moved to cells at arterial injury ...

Omega-3 fatty acids may help heal a broken heart

2013-05-30
Bethesda, MD—Procedures like angioplasty, stenting and bypass surgery may save lives, but they also cause excessive inflammation and scarring, which ultimately can lead to permanent disability and even death. A new research report appearing in The FASEB Journal, shows that naturally derived compounds from polyunsaturated fatty acids (omega-3s) may reduce the inflammation associated with these procedures to help arteries more fully and completely heal. "Our study suggests that biologically active, naturally occurring compounds derived from omega-3 PUFAs reduce inflammation ...

Twitter a popular source for vaccination information, debate

2013-05-30
Washington, DC, May 30, 2013 – Twitter is a popular source for receiving and sharing new information about vaccines, and also a basically reliable one, according to a study published in the June issue of the American Journal of Infection Control, the official publication of the Association for Professionals in Infection Control and Epidemiology (APIC). Researchers from the University of Texas at Austin analyzed 9,510 vaccination-related tweets from one week in January, 2012 to determine the most popular and influential messages. A final sample of 2,580 tweets that had ...

Interleukin-22 protects against post-influenza bacterial superinfection

2013-05-30
Researchers from the Pasteur Institute, Lille, France have shown in a mouse model that interleukin-22 protects against bacterial superinfections that can arise following influenza. Their research is published in the June 2013 issue of the Journal of Virology. Influenza A viral infection can lead to primary pneumonia and, later on, to serious complications including secondary bacterial pneumonia and sepsis. Post-influenza bacterial superinfections that occur during seasonal epidemics and pandemics are of great concern to human health and impose a considerable socio-economic ...
