Geron Corporation (Nasdaq: GERN) today reported its scientists and collaborators have demonstrated that human embryonic stem cell (hESC)-derived cardiomyocytes improve heart function when transplanted after myocardial infarction.
When human heart muscle cells derived from embryonic stem cells are implanted into a rat after a heart attack, they can help rebuild the animal’s heart muscle and improve function of the organ, scientists report in the September issue of Nature Biotechnology.
Working with embryonic mouse brains, a team of Johns Hopkins scientists seems to have discovered an almost-too-easy way to distinguish between ?true? neural stem cells and similar, but less potent versions.
Eleven more cases of West Nile virus have been reported to the Nebraska Department of Health and Human Services (DHHS) this week, bringing the total cases reported this year to 38.
For most children and teens, the beginning of a new school year is just around the corner. Not only will they be hitting the books again after a three-month-long summer break, but many of them will also participate in after-school activities.

Physicians treating patients who have suffered tympanic membrane perforation as a result of blast should also look for signs of comcomitant brain or neurologic injury, according to a study published in the August 23 edition of the New England Journal of Medicine.
The UK urgently needs to reorganise stroke services to improve outcomes for patients, argues a senior doctor in this week?s BMJ.
A neuroscientist working at University College London has devised the first experimental method to induce an out-of-body experience in healthy participants. In a paper published today in Science, Dr. Henrik Ehrsson, UCL Institute of Neurology, outlines the unique method by which the illusion is created and the implications of its discovery.
Researchers at the University of Wisconsin-Madison report this month that sildenafil increases the amount of oxytocin released by stimulation of the posterior pituitary gland, a small structure directly underneath the brain that regulates hormone levels in response to neural signals.
