Should Doctors ‘Google’ Their Patients?

Posted 15 October 2013 by Jalees Rehman

Here is an excerpt from my latest post on the 3Quarksdaily blog:   Beware of what you share. Employers now routinely utilize internet search engines or social network searches to obtain information about job applicants. A survey of 2,184 hiring managers and human resource professionals conducted by the online employment website CareerBuilder.com revealed that 39% use social networking sites to research job candidates. Of the group who used social networks to evaluate job applicants, 43% found content on a social networking site that caused them to...

Male Contraception

Posted 31 July 2013 by Jalees Rehman

My recent essay for Aeon Magazine discusses the development of newer male contraceptives which may offer a degree of reliability and reversibility similar to that of female contraceptives. Male hormonal contraceptives have been tested in small clinical trials since the 1970s, but none of them have been approved for general use. Research funding agencies and pharmaceutical companies need to make the necessary investments and forge partnerships so that the stalled research in male contraception can be revitalized. It is a...

Some Highlights of the Live Chat: “Are We Doing Science the Right Way?”

Posted 8 February 2013 by Jalees Rehman

On February 7, 2013, ScienceNOW organized a Live Chat with the microbiologists Ferric Fang and Arturo Casadevall that was moderated by the Science staff writer Jennifer Couzin-Frankel and discussed a very broad range of topics related to how we currently conduct science. For those who could not participate in the Live Chat, I will summarize some key comments made by Fang and Casadevall, Couzin-Frankel or other commenters.   I have grouped the comments into key themes and also added some...

Recent Study Raises Questions About Using Adult Stem Cells for Chronic Heart Disease

Posted 15 November 2012 by Jalees Rehman

A recent clinical study (POSEIDON Randomized Trial) investigated the effects of transplanting bone marrow derived adult stem cells into patients with known heart disease. The results were presented at the 2012 American Heart Association (AHA) meeting in Los Angeles and also published in the article "Comparison of Allogeneic vs Autologous Bone Marrow–Derived Mesenchymal Stem Cells Delivered by Transendocardial Injection in Patients With Ischemic Cardiomyopathy: The POSEIDON Randomized Trial". The article by Dr. Joshua Hare and colleagues appeared in the online... Read more

Science Journalism and the Inner Swine Dog

Posted 5 November 2012 by Jalees Rehman

A search of the PubMed database, which indexes scholarly biomedical articles, reveals that 997,508 articles were published in the year 2011, which amounts to roughly 2,700 articles per day. Since the database does not include all published biomedical research articles, the actual number of published biomedical papers is probably even higher. Most biomedical researchers work in defined research areas, so perhaps only 1% of the published articles may be relevant for their research. As an example, the major focus of... Read more

The Importance of Being Embryonic

Posted 25 October 2012 by Jalees Rehman

There are three broad categories of human stem cells: 1) adult stem cells, 2) embryonic stem cells (ESCs) and 3) induced pluripotent stem cells (iPSCs). Adult stem cells can be found in selected adult tissues, such as the hematopoietic stem cells in the bone marrow which give rise to a variety of blood cells on a daily basis in an adult. Such adult stem cells are quite rare and, when compared to ESCs, somewhat limited in the type of cells... Read more
