Cloud top temperatures in storms within Tropical Cyclone Uriah grew colder over the last couple of days, according to infrared imagery from NASA's Aqua satellite. That's an indication of stronger uplift in a tropical cyclone and a stronger storm. NASA-NOAA's Suomi NPP satellite saw the storm when it was struggling against wind shear, and two days later NASA's Aqua satellite saw Uriah reach hurricane-strength after the shear weakened.

Mothers of children with Autism Spectrum Disorder (ASD) often experience stress and suffer from sleep deprivation. Sacrifices almost always follow as they abandon professional careers and personal ambitions, believing that care for their children "comes first."

But is maternal abandonment of aspirations and interests really beneficial for the ASD child? A new Tel Aviv University study finds that a mother's positive attitude to involvement in everyday activities and a sense of competency in the performance of parental tasks accounts for a significant proportion of her children's successful participation in day-to-day activities.

Though wealthy elites and fad-chasing food activists have promoted the idea that salt is a killer, the science doesn't show that. Instead, links are correlational. Asia has always been held up as a standard for health but as their incidence of hypertension has risen, as many have blamed salt as they have a diet beyond what peasants could afford in the past.

On February 15th, 2013, as the approach of asteroid (367943) Duende was being closely monitored,  something far more alarming happened. Duende approached the Earth was expected to pass nearly 27,700 km above the Earth's surface, well inside the boundaries of the ring of geosynchronous satellites but nearly perpendicular to it, but then the Chelyabinsk superbolide entry occurred, followed by the explosion and the fall of the large meteorite in the Russian Lake Chebarkul. 

It caused damage to hundreds of buildings and injuries to nearly 1,500 people. 

Researchers have identified a gene which can be used to predict how susceptible a young person is to the mind-altering effects of smoking marijuana, an increasing concern as the cultural movement shifts toward legalization.  Around one percent of cannabis users develop psychosis. It is known that smoking cannabis daily doubles an individual's risk of developing a psychotic disorder, but it has been difficult to establish who is most vulnerable.
