1:00 PM | Right Turn: Why Janet Rossant is optimistic about the future of regenerative medicine
. If you haven’t heard the name Janet Rossant, my guess is that you aren’t part of the stem cell community or you spend a little too much time in the lab. Dr. Rossant is Chief of Research at the Hospital for Sick Children in Toronto, Canada and she leads the new Ontario Institute for...Read more

3:09 PM | The dermal cup, home to the elusive dermal stem cell
> The scientific community has long sought to uncover the identity of a true dermal stem cell. While many unique cell populations have been described in the literature, some of which are predictive of a dermal stem cell, the exact location and behavior of this cell has largely eluded us. In a landmark paper published...Read more

11:37 AM | When can you have sex after a heart attack? Most doctors do not talk about it.
Each year in the United States about 720,000 people have heart attacks and about 124,000 people in the UK and 55,000 people in Australia will have them as well. Since the 1980s, survival rates from heart attacks have improved – a lot of people get them, but more and more people are surviving. A recent study of patients in Denmark showed that in 1984-1988 31.4% of patients died within a month of having a heart attack. From 2004-2008 this was... Read more

2:36 PM | Right Turn: My bloody valentine (a new StemCellShort video)
> The blood stem cell (or hematopoietic stem cell as it’s known in scientific parlance) was the first stem cell to be identified, which makes it a bit of a celebrity, as stem cells go. Here in Canada, we like to think of Drs. James Till and Ernest McCulloch, who made that initial discovery in...Read more

12:11 AM | Combined constraints from BICEP2, Keck, Planck and WMAP on primordial gravitational waves
This week, the joint analysis of BICEP2 (+ BICEP2's successor Keck) and Planck has finally arrived. The result is more or less what was expected, which is that what BICEP2 saw last year in the B-mode polarisation signal of the CMB was not actually primordial gravitational waves (as had originally been hoped and claimed), but was unfortunately actually due to dust in the Milky Way. Such is life. Though we did of course have the best part of a year to come to grips with this reality.Combined […]

5:26 PM | Literature and Philosophy in the Laboratory Meeting
Research institutions in the life sciences engage in two types of regular scientific meet-ups: scientific seminars and lab meetings. The structure of scientific seminars is fairly standard. Speakers give Powerpoint presentations (typically 45 to 55 minutes long) which provide the necessary scientific background, summarize their group's recent published scientific work and then (hopefully) present newer, unpublished data. Lab meetings are a rather different affair. The purpose of a lab meeting […]

10:13 PM | MS HSCT
Multiple sclerosis, or MS, is an autoimmune disorder that affects the brain and spinal cord. The immune system destroys the patient’s own myelin sheath, the protective membrane that surrounds nerve cells, thus disrupting communication with the central nervous system. About 50 percent of patients are unable to walk within 25 years of their diagnosis. Most existing […]
