Fighting bacteria with mucus
Slimy layers of bacterial growth, known as biofilms, pose a significant hazard in industrial and medical settings. Once established, biofilms are very difficult to remove, and a great deal of research has gone into figuring ...
Do snails need their slime trails to move ahead? It's a sticky question
(PhysOrg.com) -- High-resolution videos of moving snails and slugs reveal the details of how snails get around on their own distinctive brand of slime.
Naked mole-rats may hold clues to pain relief
Naked mole-rats evolved to thrive in an acidic environment that other mammals, including humans, would find intolerable. Researchers at the University of Illinois at Chicago report new findings as to how ...
The new T. rex: A leech with an affinity for noses
A new leech species with ferociously large teeth -- recently discovered in noses of children that swam in Peruvian rivers -- is providing insight into the evolutionary relationships among all the leeches that ...
Biodegradable nanoparticles slip through mucus
(Phys.org) -- Researchers at Johns Hopkins University (JHU) have created biodegradable, ultra tiny, nanosized particles that can easily slip through the body's sticky and viscous mucus secretions to deliver a sustained-release ...
Scientists discover how a bacterial pathogen breaks down barriers to enter and infect cells
Scientists from the Schepens Eye Research Institute, a subsidiary of Mass. Eye and Ear and affiliate of Harvard Medical School, have found for the first time that a bacterial pathogen can literally mow down protective molecules, ...
Earthworms can survive and recover after 3-week drought stress
Earthworms are a welcomed sight in many gardens and yards since they can improve soil structure and mixing. But they are hard to find in the drier soils of eastern Colorado where water and organic matter ...
Copper + love chemical = big sulfur stink
When Hiroaki Matsunami, Ph.D., at Duke set out to study a chemical in male mouse urine called MTMT that attracts female mice, he didn't think he would stumble into a new field of study.
Frog feet could solve a sticky problem
Tree frogs have specially adapted self-cleaning feet which could have practical applications for the medical industry.
The need to feed programs Campylobacter's 'Sat Nav'
A rumbling tummy is our body's way of telling us "it's time for lunch". Likewise, bacteria need to know when it's time to eat.
Evolutionary egg question answered: Turtle goo reduces oxygen
(Phys.org)—Some reptile species give birth to live young, but turtles have never evolved this ability. New research is revealing why.
Biodegradable particles can bypass mucus, release drugs over time
Johns Hopkins University researchers have created biodegradable nanosized particles that can easily slip through the body's sticky and viscous mucus secretions to deliver a sustained-release medication cargo.
The ins and outs of building the sperm tail
Sperm swim, lung cells sweep mucus away, and the cells in the female Fallopian tube move eggs from the ovary to the uterus. Underlying these phenomena are flagella slender, hair-like structures extending ...
Pig stomach mucins are effective as anti-viral agents for consumer products
Mucus often elicits strong revulsion, but to MIT biological engineer Katharina Ribbeck, it is a fascinating material.
