Research at Washington University School of Medicine in St. Louis suggests that the accurate diagnosis of early stage endometrial cancer requires that the abdominal lymph nodes always be removed and checked for signs of cancer. The recommendation extends even to women with tumors that seem to have the smallest risk of spread. The study will be presented June 2 at the American Society of Clinical Oncology (ASCO) meeting in Chicago, Ill.

The study indicates that by examining the lymph nodes i

Assisted reproduction can safely help HIV positive men to become fathers without infecting their partners, according to new research from French fertility experts.

But, the news is not so good for HIV positive women. Assisted reproduction techniques do not seem to provide the same success for them, the researchers reported today (Thursday 29 May) in Europe’s leading reproductive medicine journal Human Reproduction[1].

Dr Jeanine Ohl and her Strasbourg-based team carried out various

An international team of astronomers headed by Dr. Michael Drinkwater (Queensland, Australia), Dr. Michael Gregg (Livermore, USA) and Dr. Michael Hilker from the University of Bonn has discovered a new kind of small, very compact galaxy. Their findings will be published in the next edition of the prestigious academic journal Nature on 29th May. This new type of galaxy could help to explain the discrepancy between observations and cosmological models.

The galaxies in our universe are not all

Theories abound as to why organisms favour sexual reproduction, but testing these has been notoriously difficult. A common view is that sexual reproduction helps to reduce the effects of damaging mutations within a population. Now researchers from the Rockefeller University have tested this premise, using careful measurements of bacterial populations, and provide evidence against it. The research published today in Journal of Biology examines how mutant bacteria respond to different forms of

A new method to accurately measure quantities of a cheese-ripening enzyme in milk could reduce the time and cost of producing cheese, according to a report by Purdue University researchers.

Infrared spectroscopy was used in combination with statistical analysis to determine the concentration of plasminogen, a form of the enzyme integral to cheese manufacturing. The study, by co-authors Lisa Mauer and Kirby Hayes, both assistant professors in the Department of Food Science, is published in th

Scientists are using new imaging technology to help them perform “virtual biopsies,” – biological profiles of specific tumors that may help predict a patient’s response to treatment and probability of long-term survival. This whole new realm of imaging is called functional MRI (magnetic resonance imaging), a process that offers insight into a tumor’s character, not just its superficial structure.

Using functional MRI, Dr. Michael Knopp, a radiologist and a member of The Ohio State
