Female orgasm seems to be a happy afterthought of our evolutionary past when it helped stimulate ovulation, a new study of mammals shows.
The role of female orgasm, which plays no obvious role in human reproduction, has intrigued scholars as far back as Aristotle. Numerous theories have tried to explain the origins of the trait, but most have concentrated on its role in human and primate biology.
Existing models for measuring health impacts of the human diet are limiting our capacity to solve obesity and its related health problems, claim two of the world's leading nutritional scientists in their newest research.
Researchers have identified 788 biomarkers in blood that could be used to develop an early stage cancer screening test for the general population.
The study, led by the University of Sheffield, is the first to create a comprehensive list of relevant cancer blood biomarkers that have been researched in the last five years. The study also groups them by molecular function and records the technologies that can be used to detect them.
Should we be warning consumers about over-consumption of meat as well as sugar?
That's the question being raised by a team of researchers from the University of Adelaide, who say meat in the modern diet offers surplus energy, and is contributing to the prevalence of global obesity.
Breaking up the rainforest into small 'forest islands' means more species are being forced to live on the forest edge, prompting a decline in species sensitive to changes in light, moisture and temperature.
A new, epidemic strain of C. difficile is proving alarmingly deadly, and new research from the University of Virginia School of Medicine not only explains why but also suggests a way to stop it.
Griffith University tropical disease researchers have joined together with a host of international laboratories to advance drug discovery for major topical diseases through the creation and testing of the Malaria Box.
In a paper published this week in the top journal PLoS Pathogens, the global team present findings on a panel of 400 chemical compounds -- dubbed the "Malaria Box" -- with potential application as therapeutic starting points for diseases like malaria, trypanosomiasis and toxoplasmosis.
In a recent study of girls and women diagnosed with at least one autoimmune disease, vaccination against human papillomavirus (HPV) did not increase the risk of developing another autoimmune disease. In fact, being vaccinated was associated with a slightly reduced risk compared with not being vaccinated.
The study included all 70,265 girls and women between 10 and 30 years of age in Sweden in 2006 to 2010 diagnosed with an autoimmune disease.
In a perfect grocery-shopping world, the supermarket where you usually shop would have an online presence that perfectly mirrored its bricks-and-mortar store, with the same selection of products and a minimal online-offline price difference. According to new research that's forthcoming in the September issue of the Journal of Retailing, grocery retailers that make an effort to create such a site and do the analytics necessary to find and retain customers will come out winners in this increasingly competitive market.
Before online shopping, if a store didn't carry the item you wanted it could take days or weeks to get it, if the store would even make a special order. That was then. Now, there's no reason for retailers not to take advantage of the unlimited retail space online and offer everything they sell. Recent research supports this approach: the more products offered online, the greater the revenue for the retailer.
A new research report appearing in the August 2016 issue of the Journal of Leukocyte Biology reveals a potentially new therapeutic target for preventing or stopping preterm labor. Specifically, using mice, researchers from the United States show that blocking specific cell signaling pathways may reduce the risk of preterm labor caused by the immune system or inflammation, or stop it altogether. This discovery is important because according to the U.S.
A new study by a team of scientists from the University of Malta and the Institut de Génétique Moléculaire de Montpellier (CNRS/Université de Montpellier) could help develop treatment strategies for a crippling disorder that was the focus of the Ice Bucket Challenge, the world's largest global social media phenomenon. The findings uncover a mechanism that explains how motor neuron disease develops.
A study released in the July 2016 issue of the American Journal of Roentgenology found that biphenotypic primary liver carcinoma (also called hepatocholangiocarcinoma) may be misclassified as hepatocellular carcinoma (HCC) if interpretation is based on major imaging features alone.
A recent analysis indicates that more than 1700 liver transplantations are performed annually in Brazil. While Brazil performs more liver transplant surgeries than anywhere else in Latin America and is third worldwide in absolute terms, the country averages only 5 to 10 liver transplants per million population due to its increasing population and inadequate donor organ supply.
Investigators also found that access to liver transplantation in the underprivileged North, Midwest, and Northeast regions of Brazil is scarce.
SILVER SPRING, Md. - A team of researchers, led by Drs. Merlin Robb and Jintanat Ananworanich of the U.S. Military HIV Research Program (MHRP) at the Walter Reed Army Institute of Research, has found that when antiretroviral therapy (ART) is initiated during early acute HIV infection, it can significantly reduce total HIV DNA levels in the body, which may have implications for the goal of achieving long-term HIV remission.
