The brain sets a unique learning rate for everything we do, by self

Each time we get feedback, the brain is hard at work updating its knowledge and behavior in response to changes in the environment; yet, if there's uncertainty or volatility in the environment, the entire process must be adjusted. A Dartmouth-led study published in Neuron reveals that there's not a single rate of learning for everything we do, as the brain can self-adjust its learning rates using a synaptic mechanism called metaplasticity.


Human umbilical blood has regenerated the brains of elderly mice

Researchers have regenerated the memories and learning abilities of elderly mice by injecting their brains with proteins taken from human umbilical cord blood.



The blood of human teenagers had previously been shown to rejuvenate ageing mice, but this new study shows that blood from the umbilical cords of babies could have even more powerful effects.

New AI Can Write and Rewrite Its Own Code to Increase Its Intelligence

A company has developed a type of technology that allows a machine to effectively learn from fewer examples and refine its knowledge as further examples are provided. This technology could be applied to everything from teaching a smartphone to recognize a user's preferences to helping autonomous driving systems quickly identify obstacles.


This new graphene-based electrode could boost solar storage by 3,000%

Drawing inspiration from the plant world, researchers have invented a new electrode that could boost our current solar energy storage by an astonishing 3,000 percent.



The technology is flexible and can be attached directly to solar cells - which means we could finally be one step closer to smartphones and laptops that draw their power from the Sun, and never run out. 


From decapitation to consciousness: how one nerve connects body, brain, and mind

The relationship between mind, brain, and body has kept philosophers and scientists busy for centuries. Some of the first interesting – albeit gruesome – experiments on the role of the body in human consciousness considered life after decapitation.

Immunity against melanoma is only skin deep

In a newly published study, researchers at Dartmouth's Norris Cotton Cancer Center find that unique immune cells, called resident memory T cells, do an outstanding job of preventing melanoma. The work began with the question of why patients with melanoma who develop the autoimmune disease called vitiligo, have such a good prognosis. Vitiligo is an autoimmune skin condition against normal healthy melanocytes, which causes the loss of skin pigmentation in blotches. Using mouse models of melanoma and vitiligo, the research team found that resident memory T cells permanently reside in...
