eight photos of sythetic mouse embryos in various stages of development

1st synthetic mouse embryos — complete with beating hearts and brains — created with no sperm, eggs or womb

For the first time, scientists have created mouse embryos in the lab without using any eggs or sperm and watched them grow outside the womb. To achieve this feat, the researchers used only stem cells and a spinning device filled with shiny glass vials.  The experiment is a “game changer,” Alfonso Martinez Arias, a developmental …

Can We Rejuvenate Aging Brains?

Summary: Researchers discuss current studies about cognitive rejuvenation and discuss steps we can take to help protect our brains as we age. Source: Stanford Neuroscientist Tony Wyss-Coray, Ph.D., has spent 20 years unearthing and examining various molecules with neuroprotective and neurodegenerative properties. These molecules are found in or on different cell types in the brain …

The Brain’s Drainage System in 3D

Summary: The CSF drainage pathways are similar between mice and humans, researchers discovered. Source: Yale Meningeal lymphatic vessels are potential targets to treat brain diseases. Laboratories at Yale and the Paris Brain Institute (Pitié-Salpêtrière Hospital, Paris) have imaged brain drainage by meningeal lymphatics in mice and in humans. The recent Journal of Experimental Medicine paper led by …

Researchers Call for New Studies to Learn How Our Brains Change When We’re Awake After Midnight

Summary: A new hypothesis suggests when people are awake during the biological circadian night there are neurophysiological changes in the brain that alters the way in which we interact with the world, especially when it comes to impulse control, information processing, and reward processing. Source: Mass General If you’ve ever stayed up late angrily commenting …
