|  Important step towards stem cell-based treatment for stroke  | Brain infarction, or stroke, is caused by a blood clot blocking a blood vessel in the brain, which leads to interruption of blood flow and shortage of oxygen. Now a reserach group has taken an important step towards a treatment for stroke using stem cells. | Read More » Understanding DNA damage from common radiation threat, low-energy electrons  | Every day, all day, our DNA gets beaten up by chemicals and radiation -- but remarkably, most of us stay healthy. Now, an investigation has produced insights into a little-studied but common radiation threat to DNA: low-energy electrons (LEEs), with energies of 0-15 electron volts. | Read More » Nano-dwarves turn tumor assassins  | Chemotherapy is often preferred for fighting cancer, but its side effects can be considerable. A new technique may reduce these in future: nanoparticle-encapsulated substances could kill off tumor cells selectively. This will be easier on patients. | Read More » Children with brain injuries nearly twice as likely to suffer from depression  | Researchers have found that compared to other children, 15 percent of those with brain injuries or concussions were diagnosed as depressed -- a 4.9 fold increase in the odds of diagnosed depression. | Read More » Reading ancient climate from plankton shells  | Climate changes from millions of years ago are recorded at daily rate in ancient sea shells, new research shows. | Read More » Epigenetics: A key to controlling acute and chronic pain  | Epigenetics, the study of changes in gene expression through mechanisms outside of the DNA structure, has been found to control a key pain receptor related to surgical incision pain, according to a new study. This study reveals new information about pain regulation in the spinal cord. | Read More » New microscopes reveal live, developing cells in unprecedented 3-D clarity  | Researchers have developed two new microscopes, both the first of their kind. The first captures small, fast moving organisms at an unprecedented rate and the second displays large cell samples in three dimensions while decreasing the amount of harmful light exposure to the cells. Both microscopes surpass in clarity any other currently on the market. | Read More » Green algae move to the beat: Flagellar synchronization of swimming algae explained  | Researchers explain the flagellar synchronization of swimming algae. The beating of flagella is one of the basic principles of movement in the cellular cosmos. However, up to now, scientists were unsure as to how the movements of several of these small cellular appendages are synchronized. | Read More » | |
