Ingestion of afterbirth appears to promote maternal behavior in mammals

A behavioral neuroscientist at the University at Buffalo holds that the ingestion of afterbirth by a mother, a feature of pregnancy in nearly all non-human mammals, not only relieves postpartum pain, but optimizes the onset of maternal behavior by mediating the activity of specific opioid activity circuits in the brain.

Not enough evidence to say gun laws reduce violence

Despite a proliferation of gun registration requirements, bans on specific firearms and “zero tolerance” policies for guns in schools over the past three decades, the jury is still out on whether these laws help prevent gun violence, according to a new review of studies in the American Journal of Preventive Medicine.

Alan List, M.D., leader of the Hematologic Malignancies Program at the H. Lee Moffitt Cancer Center & Research Institute, recently conducted a phase I/II trial of the experimental drug Revlimid showing promise as an innovative way to treat patients with myelodysplastic syndrome (MDS), a form of pre-leukemia.

Researchers show how attention enhances visual perception

The researchers, from NYU's Department of Psychology and Center for Neural Science, found that attending to, or selectively processing information from a given location without directing our eyes to that location, enhances performance in visual tasks as well as the neural activity underlying the processing of ensuing images. The results are published in the latest issue of the journal Neuron.

People with severe illnesses and disabilities don't wallow in misery and self-pity

The researchers made their surprising finding by having 49 pairs of dialysis patients and healthy people report their mood every few hours for a week, using a handheld personal digital assistant (PDA) such as a Palm. The patients had all been in dialysis for at least three months, visiting a hemodialysis center three or more times a week for hours at a time to have their blood cleaned because their kidneys had failed.

First evidence of cardiac progenitor cells

The first evidence of cardiac progenitor cells – rare, specialized stem cells located in the newborn heart of rats, mice and humans – has been shown by researchers at the University of California, San Diego (UCSD) School of Medicine. The cells are capable of differentiation into fully mature heart tissue.
