Toxoplasma remodels host cell surfaces to trigger invasion
Before the parasite Toxoplasma gondii can invade a cell, it has to know it has reached the right place. New…
Scientists discover tiny protein region that shapes tooth enamel
Tooth enamel looks simple from the outside and consists of a hard, smooth surface built to withstand years…
Scientists capture how bacteria build their protective antibiotic-resistant barriers
Gram-negative bacteria are responsible for causing several infections that are hard to treat, owing to their high resistance…
Cigarette smoke extract primes airway cells for greater nanoplastic damage
A laboratory model reveals how smoke-damaged epithelial barriers may leave airway cells more vulnerable to a second environmental…
Too little or too much iodine may push immunity off balance
A cross-species review traces how iodine influences immune defenses and why the boundary between benefit and harm remains…
New single-protein analysis technique provides unprecedented information on scramblases
A new single-protein analysis technique gives researchers an unprecedented ability to study proteins called scramblases, which have critical…
Novel antimicrobial peptides from dromedary camels offer hope against antibiotic resistance
Antimicrobial resistance poses a growing global health crisis, with few new antibiotics in development. Researchers at Sultan Qaboos…
Neuron lattice structure may guard against neurodegeneration
Brain cells are constantly swallowing material from the fluid that surrounds them – signaling molecules, nutrients, even pieces of their own surfaces – in a process…
Why some bacteria survive antibiotics and how to stop them
New study reveals that bacteria can survive antibiotic treatment through two fundamentally different “shutdown modes,” not just the…
New insights into alcohol-related DNA damage and cancer risk
Alcohol consumption leads to the formation of a toxic compound called acetaldehyde, which damages DNA. A research team…
