Scottish heather honey is best for beating bacteria
Honey has long been known for its anti-bacterial properties: it was prized by the ancient Egyptians and is widely used today in veterinary medicine as a wound dressing.
Tissue loss triggers regeneration in planarian flatworms
Unlike humans, planarian flatworms have the remarkable ability to regrow any missing body part, making them an ideal model with which to study the molecular basis of regeneration.
Researchers use nanoparticles to speed up or slow down angiogenesis
Unexpected discovery of the ways cells move could boost understanding of complex diseases
A new discovery about how cells move inside the body may provide scientists with crucial information about disease mechanisms such as the spread of cancer or the constriction of airways caused by asthma. Led by researchers ...
New nerve and muscle interfaces aid wounded warrior amputees
Since 2000, more than 2,000 servicemembers have suffered amputated limbs. DARPA's breakthrough research with advanced prosthetic limbs controlled by brain interfaces is well documented, but such research is ...
Human scabs serve as inspiration for new bandage to speed healing
Human scabs have become the model for development of an advanced wound dressing material that shows promise for speeding the healing process, scientists are reporting. Their study appears in the journal ACS Ap ...
Science devises ways to recycle crustacean shells
It was only a matter of time before scientists found a way to recycle the 750 000 tonnes of crustacean shells which are disposed of in the EU every year.
Wound healing: 'See-saw' switch sends cells on the march
Many genes are transcribed into messenger RNA (mRNA) molecules that provide instructions for protein synthesis. Other genes encode regulatory RNAs known as 'microRNAs', which can block protein translation ...
Bacteria adapt and evade nanosilver's sting
(Phys.org) —Researchers from UNSW have cautioned that more work is needed to understand how micro-organisms respond to the disinfecting properties of silver nano-particles, increasingly used in consumer ...
Discovery of wound-healing genes in flies could mitigate human skin ailments
Biologists at UC San Diego have identified eight genes never before suspected to play a role in wound healing that are called into action near the areas where wounds occur.
Opposites attract: How cells and cell fragments move in electric fields (w/ video)
Like tiny crawling compass needles, whole living cells and cell fragments orient and move in response to electric fields—but in opposite directions, scientists at the University of California, Davis, have found. Their results, ...
Even miniscule changes in environment can cause cytoskeleton of the amoeba Dictyostelium discoideum to oscillate
(Phys.org) —The amoeba Dictyostelium discoideum is the "favourite animal" for many biologists and some physicists: the unicellular organism, which usually lives in the soil, serves as a model for a very ...
Buzz builds for honey treatments
Researchers are racing against the clock to find a viable alternative to traditional antibiotics, as bacteria continues to build resistance against new drugs at a frightening rate.
Is nanosilver toxic?
According to Finnish-Estonian joint research with data obtained on two crustacean species, there is apparently no reason to consider silver nanoparticles more dangerous for aquatic ecosystems than silver ions. The results ...
