1:28 PM | Builders and Blocks – Engineering Blood Vessels with Stem Cells
Back in 2001, when we first began studying how regenerative cells (stem cells or more mature progenitor cells) enhance blood vessel growth, our group as well as many of our colleagues focused on one specific type of blood vessel: arteries. Arteries are responsible for supplying oxygen to all organs and tissues of the body and arteries are more likely to develop gradual plaque build-up (atherosclerosis) than veins or networks of smaller blood vessels (capillaries). Once the amount of plaque […]

4:00 AM | Nontraditional Careers: Science Policy
A doctorate in biology is preparation to do more than just bench work, said Lyric Jorgenson, a PhD who now works as Science Policy Advisor and Analyst at the National Institutes of Health (NIH). "It's a degree in logic," she contends. Logic and problem solving, an interest in politics, combined with the ability to write for different audiences are essential skills for PhDs looking to make the leap into science policy. A doctorate in biology is preparation to do more than just bench work, […]

3:49 PM | Apple Does 3D Cell Culture
Andrew Pelling has a new application for the apple, but it is not the latest i-gizmo from Cupertino, CA. Pelling and colleagues at the University of Ottawa have come up with a possible solution to the limitations of traditional, two-dimensional (2D) cell culture, which does not reproduce the microenvironment and tissue architecture that surrounds cells in a living organism—the apple, the one-a-day fruit that keeps the doctor away and is an essential ingredient to the All-American […]

"Active-learning interventions," in which passive lectures are replaced with interactive activities, moving lecture materials to homework and outside readings, have been shown by STEM education researchers in recent years to be strikingly effective, but a new study published on September 2 in CBE—Life Sciences Education, published by ASCB, reveals that this strategy is especially powerful for black and first-generation college students. An active-learning strategy in an introductory […]

Throughout my PhD years, I have worked passionately on the issue of "Women in Science." Becoming the president of the Graduate Women in Science Organization (GWIS) at Florida State University gave me an opportunity to work on building connections between young professional women and those who were already well advanced in their careers. During GWIS meetings, we discuss the challenges faced by women in science and talk about personal experiences. As women in science finally move up to […]

1:18 PM | Co-Chaperone Keeps Close Watch on Mice Sperm Production
Chaperones aren't just for high-school homecoming dances. Cells have chaperones as well, chaperone proteins that ensure newly made proteins are properly folded. If protein folding goes awry, diseases associated with misfolded proteins such as Alzheimer's and Parkinson's can arise. But if one set of chaperones can throw a wet blanket on a school dance, imagine a second set of co-chaperones just to keep the chaperones in check. That's the growing picture in cellular chaperoning as folding […]

2:00 AM | The Cold Spot is not particularly cold
(and it probably isn't explained by a supervoid; although it is still anomalous)In the cosmic microwave background (CMB) there is a thing that cosmologists call "The Cold Spot". However, I'm going to try to argue that its name is perhaps a little, well, wrong. This is because it isn't actually very cold. Although, it is definitely notably spotty.That's the cold spot. It even has its own Wikipedia page (which really does need updated).Why care about a cold spot? This spot has become a thing to […]
