Cardio-respiratory synchronization may represent a new measure of health and fitness

Observation of extended episodes of one-to-one synchronization between heart rate and breathing rate for athletes suggests their training specifically contributes to an enhanced connection within the nervous system. Researchers from the School of Engineering at the University of Warwick have managed to expand the knowledge of the cardio-respiratory system after conducting an experiment measuring heart rate during fast-paced breathing. Published […]

Perception and working memory are deeply entangled, study finds

Many people have an intuitive, though incorrect, understanding of how the brain works: Our senses perceive objectively factual data, and our higher-level thought processes interpret that data, pull some levers and shape our conclusions and behavior accordingly. But perception and thought are fundamentally linked, according to research published in Nature Human Behavior last week by Dwight Kravitz, an assistant professor […]

Potassium balance and glaucoma

Retinal ganglion cells (RGCs) make up the optic nerve. When RGCs degenerate due to elevated intraocular pressure caused by glaucoma, vision is lost. Cells surrounding RGCs called Müller glia maintain a healthy ionic environment through a process called potassium siphoning, where Müller glia remove excess potassium ions through potassium channels. These glial potassium channels, such as Kir and K2P, are […]

Study suggests possible link between sugary drinks and cancer

A study published by The BMJ today reports a possible association between higher consumption of sugary drinks and and an increased risk of cancer. While cautious interpretation is needed, the findings add to a growing body of evidence indicating that limiting sugary drink consumption, together with taxation and marketing restrictions, might contribute to a reduction in cancer cases. The consumption […]

New evidence shows cytotoxic T cells can identify, invade, and destroy targets of large mass like T. gondii tissue cysts

CD8+ cytotoxic T lymphocytes can kill host cells infected with various microorganisms as well as single individual cancer cells through direct cell-to-cell contact, but their ability to destroy a target of large mass remains unexplored. A study in The American Journal of Pathology provided novel evidence on the capability of the immune system to eliminate large parasite-filled cysts associated with […]

New CT scan analysis predicts respiratory illness and death in COPD

CT scans of the lungs of smokers with chronic obstructive pulmonary disease—when analyzed by a mathematical function called airway fractal dimension—can estimate increased risk of death for a group of people who are not otherwise identified as high-risk by conventional tests. That is a major finding of clinical importance in a Journal of Clinical Investigation study led by senior author […]

Vaccination programs substantially reduce HPV infections and precancerous cervical lesions

Human papilloma virus (HPV) vaccination programs have substantially reduced the number of infections and precancerous cervical lesions caused by the virus, according to a study published today in The Lancet by researchers from Université Laval and the CHU de Québec-Université Laval Research Centre. Results are so promising that it has now become possible to envision eliminating cervical cancer as a […]

Majority of people return lost wallets – here’s the psychology and which countries are the most honest

Honesty is one of the traits we value most in others. We often assume it is a rather rare quality, making it important for us to find out who we can actually trust in this selfish world.
