Caltech creates embryo-like structures using stem cells

Researchers worldwide conduct vital research involving the understanding of the very early development of humans inside the womb using human embryos. Research of the type uses surplus embryos donated by people who have undergone in vitro fertilization. However, the amount of research conducted into these early stages of human development is extremely limited by the availability of embryos.

Micro-engineered system can harvest drinkable water day and night

Micro-engineered system can harvest drinkable water day and night

Engineers at Caltech have created tiny structures inspired by the shape of cactus spines to create a material able to harvest drinkable water from the air during the day and night. The new system combines two water-harvesting technologies into one device. The material is a micro-architected hydrogel membrane able to produce water through solar steam-water generation and fog collection.

A new wearable generator can power wireless sensors

A new wearable generator can power wireless sensors

A Caltech researcher named Wei Gao, assistant professor of medical engineering, has been developing a range of inexpensive wearable sensors and methods of powering them using the human body. Powering wearable sensors has always been the biggest challenge. While batteries are an option, they aren't ideal because of their bulk and because they run out of charge.
