+ - Smaller Testicles correlated with Better Parenting Behavior->

Submitted by Guppy
Guppy (12314) writes "A recent paper appearing in PNAS (Paywalled) measured Testicular volume and Testosterone levels in fathers of children aged 1-2 years. This information was compared against parenting surveys reported by the children's mothers, as well as MRI imaging of brain activity in the men's Ventral Tegmental Area (VTA), taken while the men were viewing photographs of their children.

The results appeared consistent with past studies hinting of correlation — both Smaller Testicles and lower testosterone levels were found to correlated with both greater reported Nuturing-type behavior, as well as greater stimulated VTA activity. The authors commented that further research was required, given the limited scope of past investigations into the subject, saying "Testicular imaging is sort of a unique niche right now."

+ - Tylenol may ease pain of existential distress, social rejection

Submitted by Guppy
Guppy (12314) writes "Does Tylenol reduce existential distress? Acetaminophen (Paracetamol) has been used to relieve mild-to-moderate physical pain for over a century, yet its actual mechanism of action continues to be debated; modern research has demonstrated an intriguing connection with the body's endocannabinoid system, raising the question of whether it may also have subtle psychological effects as well. A recent paper claims Acetaminophen can alter our response to existential challenge; previous findings have suggested that it may blunt the pain of social rejection as well."

+ - Training an Immune System to kill Cancer: A Universal Strategy->

Submitted by
Guppy
Guppy writes "A previous story reported widely in the media, and appearing both on Slashdot and XKCD described a novel cancer treatment, in which a patient's own T-cells were modified using an HIV-derived vector to recognize and kill leukemia cells. In a follow-up publication, a further development is described which allows for a nearly unlimited choice of target antigens, broadening the types of malignancies potentially treatable with the technique."
