Genotoxic stress makes your hair go gray

Those pesky graying hairs that tend to crop up with age really are signs of stress, reveals a new report in the June 12 issue of Cell, a Cell Press publication.

Dangerous liaisons: bacterial 'sex' causes antibiotic resistance

Some disease-causing bacteria are becoming resistant to antibiotics because they have peculiar sex lives, say researchers publishing new results today in the journal Science.

aPKC enzyme tells stem cells which way to divide

Driving Miranda, a protein in fruit flies crucial to switch a stem cell's fate, is not as complex as biologists thought, according to University of Oregon biochemists. They've found that one enzyme (aPKC) stands alone and acts as a traffic cop that directs which roads daughter cells will take.

For cancer cells, genetics alone is poor indicator for drug response

In certain respects, cells are less like machines and more like people.

How your brain grows might come down to how your cells divide

In the April 6 issue of the Journal of Cell Biology (JCB), Lake and Sokol report that mouse protein Vangl2 controls the asymmetrical cell division and developmental fate of progenitor neurons.

Measuring the strength needed to move chromosomes

It's about as long as the width of a human hair and only half that length across. So it's tiny - measured in millionths of a meter - and extremely tricky to manipulate. But the meiotic spindle plays so irresistibly important a role in separating our chromosomes during cell division that scientists are compelled to try to study it.

Scientists deconstruct cell division

The last step of the cell cycle is the brief but spectacularly dynamic and complicated mitosis phase, which leads to the duplication of one mother cell into two daughter cells.

Scientists discover missing link in the way cells protect themselves against cancer

Cancer Research UK scientists have discovered a missing link in the way cells protect themselves against cancer, according to research published in Genes & Development.

Leaky membranes: Another sign of old age

As parts of us age, even the membrane bound nuclei , which house the genetic instructions for life that are "written" in our DNA, begin to show considerable wear and tear, suggests a new report in the January 23rd issue of the journal Cell, a Cell Press publication.

Stem cells could be used for personalized cancer treatment

Using cancer cells from an ovarian cancer patient and human embryonic stem cells, Israeli researchers have created a cancerous tumor in a mouse that mimics the way the tumor would develop in the patient's body.

New cellular clues to understanding cancer

In the 13th January print edition of the journal Current Biology, Instituto Gubenkian de Ciencia researchers provide insight into an old mystery in cell biology, and offer up new clues to understanding cancer.

Stem cells may 'ignite' bowel cancer development

Cancer Research UK scientists have discovered for the first time that stem cells could be the root cause of bowel cancer, according to a study published in Nature.

Mouse model shows blood stem cells in action

Over a period of five years, scientists at the Johannes Gutenberg University Mainz have managed to create a genetically modified mouse in which the activity of the blood stem cells can be tracked.

Biologist provides new theory on mechanisms that control molecular motors

Biologists have known for decades that cells use tiny molecular motors to move chromosomes, mitochondria, and many other organelles within the cell, but no one has been able to understand what "steers" these engines to their destinations.

Scientists create first functional stem-cell niche model

Like it or not, your living room probably says a lot about you. Given a few uninterrupted moments to poke around, a stranger could probably get a pretty good idea of your likes and dislikes, and maybe even your future plans.

New discovery on cell division could improve chemotherapies for cancer

Researchers from the Ludwig Institute for Cancer Research at the University of California, San Diego School of Medicine have identified a key step required for cell division in a study that could help improve therapies to treat cancer.

10 Dec 2008

New insights into cell division

Biologists have discovered a mechanism that is critical to cytokinesis -- nature's completion of mitosis, where a cell divides into two identical daughter cells.

Dormant stem cells for emergencies

Many specialized cells, such as in the skin, intestinal mucosa or blood, have a lifespan of only a few days.

Discovery of new mechanism for cell division

A Swedish research group, partly financed by NWO, has discovered a new mechanism for cell division in a microorganism found in extremely hot and acidic conditions.

Scientists discover an important new layer of regulation in the cell division cycle

A Florida State University College of Medicine research team led by Yanchang Wang has discovered an important new layer of regulation in the cell division cycle, which could lead to a greater understanding of the way cancer begins.
