(a–c) Dose response effects on the median lifespan of select C. briggsae strains after treatment with chemicals that exhibited strong positive effects on the C. elegans strains. Dosing was performed only on strains that failed to respond positively in the initial tests (single dose experiments), as we did not attempt to identify peak responses, instead we only sought to identify whether positive effects could be obtained by altering doses. Chemical doses were chosen to center around the effective dose identified for C. elegans strains and were sometimes expanded after preliminary rounds of testing. ThT exhibited a positive effect on strain JU1348 at 25 μM, but was profoundly toxic to all strains at and above 100 μM

Researchers discover a drug combination that can regenerate hair cells. Within the inner ear, thousands of hair cells detect sound waves and translate them into nerve signals that allow us to hear speech, music, and other everyday sounds. Damage to these cells is one of the leading causes of hearing loss, which affects 48 million Americans...

Trigeminal neuralgia is characterized by sharp, lancinating pain in the teeth or facial area. The standard treatment for this chronic nerve pain can cause burdening side effects. A novel substance inhibits the pain effectively and is well tolerated, as documented by the initial results of an international study involving the Center of Dental Medicine at the University of Zurich.

Trigeminal neuralgia pain bouts are triggered by touch, such as shaving, putting on make-up, showering, talking and tooth brushing, or even a gust of wind...

The fungus Pichia, a type of yeast, is linked to kids’ likelihood of developing asthma, new research shows.

University of British Columbia microbiologists have found a yeast in the gut of new babies in Ecuador that appears to be a strong predictor that they will develop asthma in childhood. The new research furthers our understanding of the role microscopic organisms play in our overall health. “Children with this type of yeast called Pichia were much more at risk of asthma,” said Brett Finlay, a microbiologist at UBC. “This is the first time anyone has shown any kind of association between yeast and asthma.”

In previous research, Finlay and his colleagues identified 4 gut bacteria in Canadian children that, if present in the first 100 days of life, seem to prevent asthma...
