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.
