Peeking inside ‘mini-brains’ could boost understanding of the human brain

Geneva, Switzerland, 7 January 2021 – ‘Mini-brains’ are pin-head sized collections of several different types of human brain cell. They are used as a tool, allowing scientists to learn about how the brain develops, study disease and test new medicines. Personalized ‘mini-brains’ can be grown from stem cells generated from a sample of human hair […]

Boost your mood with emotional brain training

It’s all about releasing negative emotions to make room for positive actions. (Charles Postiaux/Unsplash/) After a year of toxic stress ignited by so much fear and uncertainty, now is a good time to reset, pay attention to your mental health, and develop some healthy ways to manage the pressures going forward. Brain science has led […]

A study detailing this conclusion has been accepted for publication in The […]

A polymer electrode gets an electrical boost for use in E-skin devices. — ScienceDaily

Scientists around the world are working to develop electronic skins that attach to the body and monitor vital signs. These E-skins need to be comfortable, breathable, and flexible for everyday use. Gold is typically used to fabricate the electrodes that conduct electric signals in these applications. But gold is expensive, involves a complicated manufacturing process, […]

Multiple semiconductor type switching to boost thermoelectric conversion of waste heat

Tin monoselenide (SnSe), when doped with antimony (Sb), can make for a suitable candidate for the design of thermoelectric conversion elements (p-n junction device). Credit: Tokyo Tech In recent years, the energy consumption in developed countries has been rather wasteful. Nearly two-thirds of the total energy is typically discarded into the environment as “waste heat,” […]
