Petal Power By Tessa Quax and David Prangishvili, Institut Pasteur The archaeal virus SIRV2 employs an unusual means of escaping from its host. A 7-faced pyramidal structure is formed on the host cell surface from virus-encoded 10kDa protein and opens like the petals on a flower (shown on the image) to release mature virus particles. Image: Colored negative contrast electron micrograph of an isolated 7-faced pyramidal structure encoded by the virus SIRV2 in open conformation.

jtotheizzoe: Good News: Girls Outperform Boys On Science Exam Bad News: It’s Not Happening Where You Think It Is 15-year-old girls outscored boys on science exams, but not in Western Europe or the Americas. While in Eastern Europe and the Middle East girls abilities seem to exceed those of their male classmates, that doesn’t hold true in the most traditionally “scientific” nations. And that sucks. We’ve heard this bad news too many times. Girls are underrepresented in the sciences […]

11:09 PM | AMS Feedback

Beth Ayer, web editor for the AMS, has put together a form seeking feedback from mathematics students about student web/social media use, ams.org’s resources for students, and overall ams.org effectiveness. The form can be accessed at http://www.surveymonkey.com/s/ams-website-students. Please take a moment to provide your feedback to help the AMS make their information more readily available.

8:18 AM | New Semester

Since my last post before the JMM in January, I’ve begun a new semester. My goals are ambitious, as I am taking two course, finding an advisor for my Master’s thesis, and starting a new blog. In some ways my new courses seem old. I am taking algebraic geometry and algebra. Two of the main [...]

5:36 AM | 48th Known Mersenne Prime Discovered

Details from the Great Internet Mersenne Prime Search: On January 25th, prolific GIMPS contributor Dr. Curtis Cooper discovered the 48th known Mersenne prime, 257,885,161-1, a 17,425,170 digit number. This find shatters the previous record prime number of 12,978,189 digits, also a GIMPS prime, discovered over 4 years ago. More information can be found in this [...]

Embryonic Rat Thoracic Aorta Medial Layer Myoblast Cells (A-10 Line) A culture of adherent A-10 rat thoracic aorta cells was fluorescently triple-labeled with MitoTracker Red CMXRos, Alexa Fluor 350 conjugated to phalloidin, and SYTOX Green, targeting the mitochondria, filamentous actin network, and nuclei, respectively. In this image, the bright red mitochondrial network is superimposed on a deep blue actin cytoskeletal framework centered around the green nuclei.

4:40 AM | I hate missing crucial papers!

Have you ever had that sick feeling in your stomach when you find a journal paper published years ago, that is very relevant to your current work, but you had no idea it existed?This exact scenario happened to me, when I was trawling through the reference list of a taphonomy paper. I came across a paper published in 2004 titled 'Taphonomy of Freshwater Turtles: Decay and Disarticulation in Controlled Experiments' f [...]

Brain Transplant Brain transplants may seem like science fiction but for Huntington’s disease patients the concept brings hope. This progressive disorder is caused by the loss of neurons [brain cells] that die in response to the build up of a toxic mutant protein. If scientists could replace the lost cells with those containing a normal protein is it possible they could lessen the symptoms? Such an innovative technique is risky so must be tested in a model system to show that the treatment […]

Blebbing Goes Legit By Anne Weston, Cancer Research UK Lamellipodia are not the only way for cells to get about— plasma membrane blebs can also drive cell migration. Once thought to be restricted to dying cells, these spherical membrane protrusions are now thought to be particularly important in tumor cells, which have been shown to switch between the lamellipodia- and bleb-based motility. Image: Cells from culture were imaged with a JEOL 6700 Field Emission Scanning Electron Microscope, and […]

11:12 PM | ...or you could zeuter the dog, instead

The dog was on his back, sedated on a table. I was not wearing a surgical cap or a sterile gown. I held the first testicle between two fingers, pushed the needle in, and injected a little less than a milliliter of a mixture of zinc gluconate and L-arginine. Then the second testicle. And now the dog was non-surgically castrated. In a few weeks, once he was rid of the sperm he had already made, he would be sterile for the rest of his life.This product, Zeuterin, is newly released in the US […]

25 January 2013 Time to Grow? It’s a tricky balancing act. Cells must multiply so that children can grow and adults can heal, but cells which keep on growing and dividing when not required can turn into cancer. Working out how cells know when to grow, and when to stop is key to understanding and preventing cancer. These pancreatic cells have been genetically engineered and chemically treated to knock out an enzyme (called Lbk1) that suppresses tumour formation. Without the enzyme the tissue […]
