Annual screening before age 50 leads to lower proportions of advanced breast cancer
by University of Ottawa Stage–specific distribution of female breast cancer cases, ages 40 to 49 years versus ages 50 to 59 years, Canada excluding Quebec, 2010 to 2017. Note: Quebec is excluded because cases diagnosed in Quebec from 2011 onward had not been submitted to the Canadian Cancer Registry. Vertical error bars indicate 95% confidence...
Smart contact lenses for cancer diagnostics and screening
by Terasaki Institute for Biomedical Innovation Scientists from the Terasaki Institute for Biomedical Innovation (TIBI) have developed a contact lens that can capture tears for the detection of exosomes, nanometer-sized vesicles found in bodily secretions which have the potential for being diagnostic cancer biomarkers.

To break through bacteria’s protective shield, target the shield-maker
Antibiotic-resistant bacteria are making it increasingly difficult to combat many infections. And types of bacteria classified as “Gram-negative” — the Gram staining method used to differentiate bacteria — are tough to combat as they have an additional protective layer of their cell wall. Yale researchers have now uncovered a key part of the process that generates...
Researchers introduce rapid diagnostic test for Listeria
Researchers in the University of Georgia College of Engineering are developing a new way to detect potentially deadly Listeria contamination in food. Listeriosis, an infection caused by eating food contaminated by the bacterium Listeria monocytogenes, can cause severe illness in pregnant women, newborns, the elderly and people with compromised immune systems. Listeria is the third leading cause...
Vitamin D supplementation seems to alleviate depressive symptoms in adults
UNIVERSITY OF EASTERN FINLAND An extensive meta-analysis suggests that vitamin D supplementation may alleviate depressive symptoms in adults with depression. Conducted by an international team of researchers, the meta-analysis includes dozens of studies from around the world. Depressive symptoms cause a significant disease burden worldwide. The therapeutic efficacy of current antidepressants is often insufficient, which...

Secret behind ‘nic-sickness’ could help break tobacco addiction
by Robert Sanders, University of California – Berkeley Nicotine is addictive because it activates the brain’s dopamine network, which makes us feel good. UC Berkeley researchers now show in experiments on mice that nicotine in high doses also activates a recently discovered dopamine network that responds to unpleasant stimuli. This aversive dopamine network could be...
A new theory in physics claims to solve the mystery of consciousness
by Bar-Ilan University Credit: Pixabay/CC0 Public Domain How do 1.4 kg of brain tissue create thoughts, feelings, mental images, and an inner world? The ability of the brain to create consciousness has baffled some for millennia. The mystery of consciousness lies in the fact that each of us has subjectivity, something that is like to...
