UTMB team proves potential for reducing pre-term birth by treating fetus as patient

GALVESTON, Texas – The results of a study by researchers at the University of Texas Medical Branch may pave the way for a new medicine delivery system that could reduce the incidence of pre-term labor and premature birth by allowing physicians to treat the ‘fetus as the patient’. The study has been published in Science […]

MRI helps unravel the mysteries of sleep

Our state of consciousness changes significantly during stages of deep sleep, just as it does in a coma or under general anesthesia. Scientists have long believed – but couldn’t be certain – that brain activity declines when we sleep. Most research on sleep is conducted using electroencephalography (EEG), a method that entails measuring brain activity […]

Botulism breakthrough? Taming botulinum toxin to deliver therapeutics

IMAGE: The toxin-based delivery platform consists of the modified botulinum toxin at upper left (protease domain in gold, translocation domain in blue, and receptor-binding domain in purple) and the nanobody (the… view more  Credit: Sicai Zhang/Dong Lab, Boston Children’s Hospital While rare, botulism can cause paralysis and is potentially fatal. It is caused by nerve-damaging toxins […]

Preserving workers’ hearing health by improving earplug efficiency

IMAGE: Ear canal modelisation view more  Credit: ÉTS Noise exposure accounts for 22% of worldwide work-related health problems. Excessive noise not only causes hearing loss and tinnitus, but also increases the risk of cardiovascular diseases. To provide protection, workers normally wear earplugs. However, commonly available earplugs are often uncomfortable, since they don’t fit everyone’s ears equally […]

Polysaccharides from red algae affect mice immune systems, say FEFU scientists

Carrageenans, biologically active polysaccharides isolated from red algae and widely used in the food industry as stabilizers, thickeners, or jelly agents have an express effect on the immune systems of mice, a study reports. The research was carried out by scientists from the School of Biomedicine of Far Eastern Federal University (FEFU), Far Eastern Branch […]

Comb of a lifetime: a new method for fluorescence microscopy
