Are women more sharp in remembering faces and names than men?

We might have experienced incidents when one person will be remembering an incident from past clearly while the other from the opposite sex would have forgotten it altogether. In such scenarios, women are more accurate than men, and studies have been done on the same to prove that women are better at remembering things than men. In humans, there are various types of memories and “episodic” memories are one of the most important among them. "Episodic memories are consciously recollected memories related to personally experienced events," explains the authors of the Encyclopedia of Neuroscience and that it cannot be recollected by everyone. There are many factors influencing the memory of a person, one of them being gender, according to the recent study. This analysis was drawn from experiments where meta-analysis of 617 studies that took place in 1973–2013, including more than 1.2 million participants overall. Results showed that women are better at remembering faces, where they left an object and what happened in a movie, while men are better at remembering navigational information and abstract information. “Generally, women perform better when it comes to remembering verbal information, such as words, sentences, texts, and objects, also the location of objects, and movies. Men can better recall abstract images and remember their way back from one location to another.", says Prof. Agneta Herlitz.

Are artificial lights in sleeping environment a threat to obesity in women?

Obesity is a major issue faced by about 70% of the U.S population. The ever increasing rate of obesity has tripled across the globe since 1970’s and is putting us in an alarming state. Diet and exercise are the key factors to keep obesity at bay and now, studies also show the role of sleep and genetics. A study was done to know whether artificial light in the sleeping environment of a woman leads to obesity. 43,722 women participated in the study and scientists divided them into groups based on the exposure of their sleeping environments to artificial light. Results showed that, lower the exposure, lower was their body mass index (BMI) and waist to hip ratio were, on average. Also, sleep duration was shorter, physical activity and healthy eating lesser. “While our study provides stronger evidence than other previous studies, it is still not conclusive. Even so, it seems reasonable to advise people not to sleep with lights on.", says Dr. Yong-Moon Mark Park. Sleeping with T.V or other light imparting devices on is a habit hard to break. Also, living in crowded places will also make it hard to lower the impacts of outside light. Next, researchers are going to focus on how natural light affects obesity and whether there is a link between artificial light and high blood pressure, type 2 diabetes etc.
