Most of us have woken up with an aching back after a sleepless night, only for that pain to then keep us awake the next night. Now Harvard scientists have discovered a possible link between pain and poor sleep, and maybe even a way to break the loop.

A drug that treats excessive daytime sleepiness and obstructive sleep apnea could be repurposed to relieve debilitating symptoms of attention deficit hyperactive disorder, without the serious health risks that stimulants may hold for older adults.

A group of US and Canadian anesthesiologists has sounded the alarm on the new class of weight-loss drugs, this time warning that they can increase the risk of serious complications for patients under sedation on the operating table.

For those who struggle to find time to exercise during the week, preferring to do most of it on the weekend, a new study has found that being a “weekend warrior” is still effective at reducing the risk of cardiovascular disease.

Getting your cat spayed is a normal part of pet ownership, but it can be expensive, invasive and not very practical on strays. Now scientists have tested a new method that renders female cats permanently sterile with a single gene therapy injection.

People suffering from ALS (amyotrophic lateral sclerosis) often have difficulty raising their arms, due to deterioration of cells in their brain and spinal cord. A new wearable system is designed to help, utilizing a pair of under-arm balloons.

One way scientists hope to lighten the burden of type 1 diabetes is through transplantation of cells that produce insulin, and novel bead-like materials offer new hope by reducing the need for immunosuppressant drugs with severe side effects.

Since the beginning of the pandemic, doctors have seen links between COVID-19 and diabetes, but is the novel coronavirus directly causing new cases of diabetes, or are we just catching more undiagnosed diabetes cases? A new study offers some answers.

A new study has identified a pattern of brain activity that seems to correlate with impairment from cannabis intoxication. The researchers suggest this novel brain-based biomarker could be a way to accurately measure THC impairment.

The results have been revealed from a study testing an algorithm designed to detect irregular heart rhythms using data from wearables. Enrolling nearly half a million subjects, the study detected undiagnosed atrial fibrillation in 98 percent of cases.

A new imaging study comparing brain activity of superagers to youthful brains highlights exactly how some older adults can maintain good memory function, and directs researchers to brain regions that could be stimulated to enhance memory in aging adults.

Fascinating new research has found a link between opioid addiction and vitamin D deficiency. The research indicates subjects with low vitamin D levels may experience heightened euphoric effects from opioids, making them more susceptible to addiction.
