You can't get blood from a stone, but it seems you can make imitation red blood cells from polymers.
Just like real blood cells the pretenders can squeeze through spaces much smaller than their own diameter and absorb and release substances to order, including oxygen.
They could be used to... Read More
The swine flu pandemic may turn out to be less severe than many had feared, but the H1N1 virus has revealed disturbing weaknesses in the nation's defenses against public health emergencies, according to a new report.

While many countries in the world are still struggling with swine flu, a new epidemic of goat flu or Q-fever has struck the Netherlands.
Q-fever, caused by Coxiella burnetii bacteria, can be secreted into the milk, urine and feces of infected animals; the amniotic fluid and placenta of pregna... Read More
Xenotropic murine leukemia virus related virus (XMRV) has been implicated in prostate cancer and chronic fatigue syndrome (CFS). Because XMRV is a retrovirus, it has been suggested that it might be susceptible to some of the many drugs available for treatment of AIDS. Of ten licensed compounds e... Read More
A new study found that certain immune cells primarily associated with asthma and allergies may enhance innate immunity and improve clearance of bacterial infections and may be an effective new therapy against bacterial infections and sepsis in humans. The researchers from Oregon Health and Scie... Read More
This story discusses the issue of hand sanitizer claims and whether they are relevant to everyday life. Microbiologist Jason Tetro from the University of Ottawa CREM (@JATetro) is quoted. Read More
Bacteria, viruses and fungi have been primarily cast as the villains in the battle for better human health. But a growing community of researchers is sounding the warning that many of these microscopic guests are really ancient allies.
Having evolved along with the human species, most of the ... Read More
As I mentioned last week, next year is to be the International Year of Biodiversity. So I thought I’d kick off the celebrations by looking at some of the funkiest beings on the planet: viruses.
Viruses have a bad reputation: in humans, they cause illnesses as varied as colds, flu, cervical ca... Read More
People infected with hepatitis C virus (HCV) face a long road of drug treatment that, in the best cases, can cure their infections and allow their livers to recover from HCV-associated liver disease, whose symptoms range from scarring and cancer to organ failure. Unfortunately, for nearly half o... Read More

The metal-metabolizing Shewanella oneidensis microbe does not just cling to metal in its environment, as previously thought. Instead, it harvests electrochemical energy obtained upon contact with the metal and swims furiously for a few minutes before landing again.
Electrokinesis is more than... Read More
Bacteria dance the electric slide, officially named electrokinesis by the USC geobiologists who discovered the phenomenon.
Their study, published online today in PNAS Early Edition, describes what appears to be an entirely new bacterial behavior.
The metal-metabolizing Shewanella oneidensi... Read More
Hundreds of thousands of swine flu shots for children have been recalled because tests indicate the vaccine doses lost some strength, government health officials said Tuesday.
The shots, made by Sanofi Pasteur, were distributed across the country last month and most have already been used, ac... Read More

Scientists have discovered a signaling pathway that tuberculosis bacteria use to coerce disease-fighting cells to switch allegiance and work on their behalf. Epithelial cells line the airways and other surfaces to protect and defend the body. Tuberculosis bacteria co-opt these epithelial cells i... Read More

For many people, essential oils are associated with sweet-smelling rooms or a relaxing bath, but their antibacterial components make them “highly efficient” in the treatment of so-called hospital “superbugs”, according to new research.
Scientists based at Sligo Institute of Technology have di... Read More
We talk a lot about the wonders of nanotechnology here at Gizmag. After all it’s easy to get caught up in the excitement surround the technology when it promises to revolutionize practically every area of human endeavor. Among its long list of anticipated benefits are new medical treatments; str... Read More
A discovery by scientists at the University of East Anglia (UEA) could contribute to the development of systems that use domestic or agricultural waste to generate clean electricity.
