Researchers at the University of Notre Dame have developed a novel, automated device capable of diagnosing glioblastoma, a fast-growing and incurable brain cancer, in less than an hour. The average glioblastoma patient survives 12–18 months after diagnosis.

The crux of the diagnostic is a biochip that uses electrokinetic technology to detect biomarkers, or active Epidermal Growth Factor Receptors (EGFRs), which are overexpressed in certain cancers such as glioblastoma and found in extracellular vesicles.

“Extracellular vesicles or exosomes are unique nanoparticles secreted by cells...

Researchers have taken looking for love to a whole new level, revealing that different types of love light up different parts of the brain. We use the word ‘love’ in a bewildering range of contexts – from sexual adoration to parental love or the love of nature. Now, more comprehensive imaging of the brain may shed light on why we use the same word for such a diverse collection of human experiences.

‘You see your newborn child for the first time. The baby is soft, healthy and hearty – your life’s greatest wonder. You feel love for the little one.’

The above statement was one of many simple scenarios presented to fifty-five ...

Scientists have discovered a mutation in SARS-CoV-2, the virus that causes COVID-19, that plays a key role in its ability to infect the central nervous system. The findings may help scientists understand its neurological symptoms and the mystery of “long COVID,” and they could one day even lead to specific treatments to protect and clear the virus from the brain.

The new collaborative study between scientists at Northwestern University and the University of Illinois-Chicago uncovered a series of mutations in the SARS-CoV-2 spike protein (the outer part of the virus that help...

Gut Bioelectricity provides a Path for ‘Bad’ Bacteria to Cause Diseases

Study discovers an electric current in the gut that attracts pathogens like Salmonella. Researchers have discovered a novel bioelectrical mechanism that pathogens like Salmonella use to find entry points in the gut lining that would allow pathogens to pass and cause infection.

How do bad bacteria find entry points in the body to cause infection?

This question is fundamental for infectious disease experts and people who study bacteria. Harmful pathogens, like Salmonella, find their way through a complex gut system where they are vastly outnumbered by good microbes and immune cells. Still, the pathogens navigate to find vulnerable entry points in the gut that would allow them to invade and infect the body.

A team of UC Davis Health researchers has discovered a novel bioelectric...
