New research reveals a mitochondrial gene that protects against dementia and other diseases of aging

New research from USC has uncovered a previously unknown genetic risk factor for Alzheimer’s disease and related dementias. The study provides insights on how these conditions, and other diseases of aging, might one day be treated and prevented. The research from the Cohen Lab at the USC Leonard Davis School of Gerontology sheds new light on the protective role of a naturally occurring mitochondrial peptide, known as humanin.

Scientists Create Immature Human Eggs From Stem Cells

Scientists Create Immature Human Eggs From Stem Cells

Scientists say they have taken a potentially important — and possibly controversial — step toward creating human eggs in a lab dish. A team of Japanese scientists turned human blood cells into stem cells, which they then transformed into very immature human eggs. The eggs are far too immature to be fertilized or make a baby. And much more research would be needed to create eggs that could be useful — and safe — for human reproduction.

In depression the brain region for stress control is larger

In depression the brain region for stress control is larger

Although depression is one of the leading psychiatric disorders in Germany, its cause remains unclear. A recent study at the Max Planck Institute for Human Cognitive and Brain Sciences (MPI CBS) in Leipzig, Germany, and the Department of Psychiatry and Psychotherapy of the University Clinic in Leipzig found that those affected by depressive disorder have a larger hypothalamus compared to their healthy counterparts.

Japan’s rovers send pictures from asteroid

Japan's rovers send pictures from asteroid

Japan's space agency (JAXA) has made history by successfully landing two robotic explorers on the surface of an asteroid. The two small "rovers", which were despatched from the Hayabusa-2 spacecraft on Friday, will move around the 1km-wide space rock known as Ryugu. The asteroid's low gravity means they can hop across it, capturing temperatures and images of the surface.

Giving Ecstasy to Octopuses Taught Researchers Something Important About the Brain

Giving Ecstasy to Octopuses Taught Researchers Something Important About the Brain

A new study suggests that humans might have more in common with octopuses than it appears: they both respond to at least one psychoactive drug in a similar, sociable way. Scientists from Johns Hopkins University and the Marine Biological Laboratory on Cape Cod found that, just like humans, notoriously reserved (and sometimes violent) octopuses act friendly and social when they’re exposed to MDMA, otherwise known as ecstasy or Molly.
