A controlled test of the electron spin resonance ESR dating method as it is currently being applied to teeth was attempted for the time range ka, beyond that of 14C, at the archaeological site of La Chaise-de-Vouthon Charente, France. ESR ages are derived from the ratio of the AD, the radiation dose needed to produce the observed ESR signal, relative to the natural, environmental dose rate ED experienced by the tooth after deposition. Since the age depends on the uranium U uptake history assumed, three ages are calculated assuming: Generally, the LU age agrees best with known ages determined by other methods, although the RU model is better for some teeth. ESR dating assumes that the fossil has not suffered recrystallization or significant diagenetic alteration. In the preliminary test, three teeth were dated. ESR dating teeth significantly underestimated the true age for the teeth: Although more teeth at La Chaise need to be tested to ascertain that the underestimation does not result from random variation commonly seen among teeth within one unit, the consistent underestimation suggests a fault in one of the assumptions underlying the dating method. The most obvious source of error lies in the difficulty in modelling the external gamma dose.

October 9, , McMaster University While exercise buffs have long used protein supplements to gain muscle, new research from McMaster University suggests one protein source in particular, whey protein, is most effective for seniors struggling to rebuild muscle lost from inactivity associated with illness or long hospital stays. The study, published online in The American Journal of Clinical Nutrition, compared the impact of different forms of protein supplements on older adults, a growing population challenged by the loss of muscle and strength, or sarcopenia, which in turn can affect balance, gait and the ability to perform the simple tasks of everyday life.

Researchers found that protein did not stop lean muscle loss caused by inactivity, however, whey supplements helped to rebuild muscle once the participants activities resumed. Whey is one of the highest quality proteins and is ideal for older persons,” says Stuart Phillips, senior author on the paper and a professor of kinesiology at McMaster. Researchers set out to compare the impact of whey versus collagen protein on muscle loss during periods of inactivity and then recovery.

Whey is considered a high-quality or complete protein, meaning it is rich in all essential amino acids and is higher in leucine, one of the essential amino acids the body cannot make itself and therefore, must derive from food. Collagen peptides, by comparison, are much lower in their leucine content, lack or are low in essential amino acids. For the study, researchers recruited men and women who were non-smokers, non-diabetic and between the ages of 65 and 80 years old.

One group of subjects consumed whey protein , the other collagen peptides, throughout the study. For a five-week period their diet was controlled, including a two-week time frame where their daily steps were restricted to per day and their calorie intake reduced by calories per day, conditions that might mimic what older people often experience during a hospital stay. Participants returned to normal activity levels during a one-week recovery period.

The team had predicted that the collagen peptide group would experience a significantly greater muscle loss than the whey protein group, but that didn’t happen.

History[ edit ] McMaster University resulted from the outgrowth of educational initiatives undertaken by Baptists as early as the s. The first courses—initially limited to arts and theology leading to a BA degree—were taught in , and the first degrees were conferred in The building is currently used as the headquarters for The Royal Conservatory of Music. As the university grew, McMaster Hall started to become overcrowded. The suggestion to move the university to Hamilton was first brought up by a student and Hamilton native in , although the proposal was not seriously considered by the university until two years later.

The university nearly became federated with the University of Toronto , as had been the case with Trinity College and Victoria College.

McMaster was back in action as they continued their tour of southwestern Ontario in London, taking on the Western Mustangs in women’s basketball action Saturday afternoon.

Hamilton, ON – A gigantic ape, measuring about 10 feet tall and weighing up to 1, pounds, co-existed alongside humans, a geochronologist at McMaster University has discovered. Using a high-precision absolute-dating method techniques involving electron spin resonance and uranium series , Jack Rink, associate professor of geography and earth sciences at McMaster, has determined that Gigantopithecus blackii, the largest primate that ever lived, roamed southeast Asia for nearly a million years before the species died out , years ago.

This was known as the Pleistocene period, by which time humans had already existed for a million years. Guangxi province in southern China, where the Gigantopithecus fossils were found, is the same region where some believe the modern human race originated. Traditional Chinese medicine maintains that dragon bones, basically fossil bones and teeth, possess curative powers when the fossils are ground into a fine powder, and ingested.

For nearly 80 years, Gigantopithecus blackii has intrigued scientists, who have pieced together a description using nothing more than a handful of teeth and a set of jawbones. Gigantopithecus blackii, the largest primate that ever lived. Sample studies further revealed that Gigantopithecus was an herbivore, feasting mainly on bamboo. Some believe that the primate’s voracious appetite for bamboo ultimately placed him at the losing end of the evolutionary scale against his more nimble human competition.

Rink’s discovery coincides with an invitation to join the renowned New York-based Explorers Club. Established in , the Club’s seven founding members included two polar explorers, the curator of birds and mammals at The American Museum of Natural History, an archaeologist, a war correspondent and author, a professor of physics and an ethnologist.

Sir Edmund Hillary is Club’s honorary chairman. Membership includes an eclectic range of field scientists and explorers from more than 60 countries.

December 15, The Dating Diaries: She loves to work-out, cook healthy food, and drink wine with friends. It had been a couple of years since I ended my four year relationship. Med school got so busy and I had been on some dates here and there. Some were good, some were boring, nothing too memorable. As I was nearing the end of my studies and heading into residency, I was ready to try online dating.

All of my friends kept encouraging me to set up a profile. I finally did — and what a disaster. It was only my second date with someone from Plenty of Fish.

When placing this tag, consider associating this request with a WikiProject. This project employed bibliometrics to analyze and rank the performance of the top universities and the top universities in six fields. It also ranked the top universities across ten science and technology fields. They representedx three criteria of scientific papers performance: The ranking methodology was alleged to have favored universities with medical schools, and in response, HEEACT added assessment criteria.

The HRLR ranking was pioneered in late within a working group in response to those concerns. The team was founded in January , in London, and started compiling and processing data, resulting in the first lists in The new HRLR ranking innovative methods sparked intense interests from many institutions and inspired several other ranking lists and scoring which are based on professional, alumni, executives, competitiveness, human capital-oriented aspects.

Nevertheless, HRLR remains to be the leader in university ranking with innovative and comprehensive approaches, and not relying merely on those aforementioned aspects. The pilot project involved a trial of over 1, universities or institutions and 5, constituent faculties in various disciplines worldwide. The top results for universities and faculties were reported at the project website. The assessment analyzes research performance as measured by publications and citations.


They were collected from a woman, thought to have been about years-old and likely pregnant when she died. Ancient female skeleton from Troy yields oldest known form of maternal infection The year-old skeleton of a young woman buried in a graveyard on the outskirts of the fabled city of Troy is yielding new insights into the evolution of bacterial infections and maternal health.

The samples yielded enough DNA to fully reconstruct the genomes of Staphylococcus saprophyticus, a common bacterial pathogen that causes urinary tract infections, and Garnerella vaginalis, found in modern pregnancy-related infections. Calcification, which likely formed as a result of the infection, created a protective mineralized layer, explain researchers. Some of the human DNA in the nodules came from a male, suggesting that the woman was indeed pregnant with a boy.

Researchers believe the cause of her death was a bacterial infection of the placenta, amniotic fluid and membranes surrounding the fetus.

Researchers at McMaster University found that female brains have a greater density of neurons in parts of the temporal lobe cortex, which is the area of the brain .

A team of genome researchers at Penn State University and experts in ancient DNA at McMaster University in Canada has obtained the first genomic sequences from a woolly mammoth, a mammal that roamed the grassy plains of the Northern Hemisphere until it became extinct about 10, years ago. The team’s research on bones preserved in Siberian permafrost will be published on 22 December by the journal Science on the Science Express Web site.

However, the mitochondrial genome codes for only a tiny fraction of an organism’s genetic information — 0. A mammoth was chosen for the study, in part, because of its close evolutionary relationship to the African elephant, whose nuclear DNA sequence has been made publicly available by the Broad Institute in Cambridge, Massachusetts USA.

Using comparisons with elephant DNA, the researchers identified million base pairs as being nuclear DNA from the mammoth, which they showed to be Collaborator Webb Miller of Penn State believes the study indicates that any organism conserved in frozen ice or a permafrost environment will be an open book to the researchers. The search is now on for more specimens from animal, plant, and man that can illuminate the route evolution took on its way from the past to the present, and can clarify the role that environmental changes may have played in the extinction of an entire species.
