Carbamate Insecticides May Increase Risk For Diabetes

Exposure to synthetic chemicals commonly found in insecticides and garden products adversely affects melatonin receptor signaling, creating a higher risk for metabolic diseases such as diabetes, University at Buffalo researchers have found. The study combined a big data approach, using computer modeling on millions of chemicals, with standard wet-laboratory experiments. Margarita L. Dubocovich, PhD, senior […]

How Light Bulbs Could Be Playing Havoc With Your Health

A recent newspaper article under the headline “High street eye test can provide early indication of dementia” highlighted yet another complex connection between the eye and the brain.

Melatonin May Link Breast Cancer And Sleep

Researchers say that the hormone melatonin appears to suppress the growth of breast cancer tumors. Although treatments based on this key discovery are still years away, the results offer an avenue for future research. The brain manufactures melatonin only at night to regulate sleep cycles. Epidemiologists and experimentalists have speculated that the lack of melatonin, […]

Melatonin Sensitivity And Diabetes Risk Link Found

A predisposition to have a pancreas that’s more sensitive to the insulin-inhibiting effects of melatonin, may be present in up to 30 percent of the population, a new study suggests. Individuals with this increased sensitivity carry a slightly altered melatonin receptor gene that is a known risk factor for type 2 diabetes. Large-scale studies have […]

Short Winter Days Trigger Aggression Hormones Differently Based On Gender

A hormonal mechanism in hamsters that connects short winter days with increased aggression in females has been discovered by Indiana University researchers. They also found it differs from the mechanism that controls this same response in males. The work, which advances basic knowledge on the connection between certain sex hormones and aggression, could go on […]
