Theories in physics come and go, some are popular yet entirely speculative and fade away quickly, like String Theory, and Superdeterminism, while others continue to provide hope for a framework that can unify gravity at the very large and very small levels.

Dry eye disease is a chronic condition estimated to affect around 360 million people. Common symptoms include uncomfortable, red, scratchy or irritated eyes.

Anecdotal claims are that laughter therapy alleviates depression, anxiety, stress, and chronic pain, while strengthening immune function but if you have clinical depression, please don't limit yourself to people saying you need to smile more and get scientific help. Laughter therapy for dry eye disease is a much less risky proposition.

Getting enough sleep is correlated to brain and heart health and after a stroke that is even more important.

A new survey finds that is when people who need it are least likely to get it. 

A cohort of 39,559 people were asked every two years how much sleep they usually get at night on weekdays or workdays. Sleep duration was divided into three categories: short, less than six hours; normal, six to eight hours; and long, eight or more hours of sleep. The group included 1,572 people who had a stroke.

A health data simulation has concluded that a single dose of the Modified vaccinia Ankara-Bavarian Nordic (MVA-BN) was 58% effective in protecting again mpox infection, a disease caused by infection with the Monkeypox virus, which is most likely in men who have sex with men and which causes a rash, along with other symptoms. 

The neurons in our brains are protected by an insulating layer called myelin. In diseases like multiple sclerosis, this protective layer is damaged and lost, leading to death of neurons and gradual disability.

Researchers in Scientific Reports are claiming the first non-human instance of an animal possessing some mental states (e.g., mental body image, standards, intentions, goals), which are elements of private self-awareness.

They show that Labroides dimidiatus (bluestreak cleaner wrasse) checked their body size in a mirror before choosing whether to attack fish that were slightly larger or smaller than themselves. 

The authors say the cleaner wrasse’s behavior of going to look in the mirror installed in a tank when necessary indicated the possibility that the fish were using the mirror to check their own body size against that of other fish and predict the outcome of fights.
