Acting as the main interface between the internal and the external world, the skin is the largest and most important organ of the human body. It is frequently exposed to many types of physical injuries or wounds, including cuts, scrapes, scratches, infections, and ulcers. Unfortunately, as one ages, the skin becomes more frail and less capable of healing itself without help. With many countries experiencing a rapid rise in the aging population, the demand for treating such skin wounds has created a greater need for accessible and effective wound ...

Cerebral organoids are three-dimensional, in vitro cultured brains that mimic the activities of the human brain. They have emerged as invaluable tools to comprehend evolution, disease pathogenesis, and neurodevelopmental processes. However, the development of these organoids is still in nascent stages with several limitations that hinder their broad applications. A major obstacle is the absence of a functional vasculature that can restrict the size of organoids, trigger cell death, and prevent cell differentiation in the organoids. To address ...

CAMBRIDGE, MA — During a chemical reaction, molecules gain energy until they reach what’s known as the transition state — a point of no return from which the reaction must proceed. This state is so fleeting that it’s nearly impossible to observe it experimentally. The structures of these transition states can be calculated using techniques based on quantum chemistry, but that process is extremely time-consuming. A team of MIT researchers has now developed an alternative approach, based on machine learning, that can calculate ...

Child psychologists have long known that play is essential for children’s cognitive development because it boosts their social, physical, and emotional skills. But beginning in the 21st century, specialists repeatedly sounded the alarm that ‘play is under siege’ for US children. Kids were playing less, and – it was feared – with a lesser quality. But are today’s parents sufficiently aware of the importance of letting their children play? Yes, found a team of researchers who tested this through a survey of the opinions of 1,172 US parents. Their results showed that today’s ...

To an everyday consumer, the best gadgets on the market have the highest speed, the largest memory, and the longest battery life.
