Study reveals promising insights on treatment to improve speech after a stroke

Lucy Mulloor woke up one morning and realized something was terribly wrong. The 45-year-old single-mom could hear her two daughters in the kitchen but couldn’t call out to them. She’d lost the ability to talk and to move the right side of her body. Mulloor managed to work her way to the side of the bed and drop onto the floor to attract the girls’ attention. The oldest called 911. Mulloor would soon learn she’d experienced a massive stroke in the night and would spend the next five months in hospital.

Exploring the effect of oxidizing compounds on melanoma cells

Melanoma is the most aggressive form of skin cancer. Although less common, it is the most serious due to its high potential for metastasis. Despite the health benefits of sunlight, prolonged exposure to ultraviolet rays is the main risk factor for developing the disease. Excessive radiation induces oxidative stress and inflammation in skin cells through photo-oxidation reactions.

Cognitively impaired older drivers less likely to cause a crash when accompanied by a passenger, study finds

Researchers from the University of Tsukuba examined variations in the likelihood of older drivers causing traffic crashes based on the presence of a passenger, utilizing nationwide traffic crash data between 2014 and 2020. Their analysis revealed that even drivers with cognitive impairment had a reduced risk of causing crashes when accompanied by a passenger.

Scientists achieve record-breaking growth in miniature, functional liver models

The liver is the body’s control tower for metabolism, powering vital functions like converting nutrients to glucose, storing fat and breaking down toxins. Over a third of the world, however, is thought to be affected by conditions including metabolic dysfunction-associated steatotic liver disease (MASLD), which jeopardize key liver functions as the condition progresses. Hepatocyte organoids—the miniature, 3D models of the organ—hold immense promise for accelerating drug development and advancing regenerative therapies.
