The cutting edge of robotics may not be a smarter Siri or a less-creepy humanoid Japanese robot. It might be a swarm of bacteria, compelled to do our bidding through a remotely controlled magnetic field.
Some of the biggest technological advances of the past two decades have involved scaling ... Read More
Researchers have succeeded in creating a surface on nano-sized cellulose crystals that imitates a biological structure. The surface adsorbs viruses and disables them. The results can prove useful in the development of antiviral ointments and surfaces, for instance.
There are many viral diseas... Read More
Scientists at the University of Kentucky, led by nano-biotechnologist Peixuan Guo, have made some critical discoveries over the past year into the operation of biomotors, the molecular machines used by viruses and bacteria in the packaging of DNA.
Biomotors function similarly to mechanical mo... Read More
The Centers for Disease Control plans to take measures to better protect lab workers and the rest of us from dangerous biological samples.
Twenty-one dead lab chickens piled up this spring at a government facility before its researchers could pinpoint why. The team had requested and received ... Read More
After studying 137 varieties of cheese collected in 10 different countries, researchers have been able to identify three general types of microbial communities that live on cheese, opening the door to using each as a 'model' community for the study of whether and how various microbes and fungi c...

It is well known that aquatic birds are a major reservoir of influenza A viruses, and that pandemic human influenza virus strains of the past century derive viral genes from this pool. The recent discovery of two new influenza A viruses in bats suggests that this species may constitute another r... Read More
Cryptococcus gattii, a virulent fungus that has invaded the Pacific Northwest, is highly adaptive and warrants global "public health vigilance," according to a study by an international team of researchers. C. gattii, which likely originated in Brazil, is responsible for dozens of deaths in rece... Read More
A new study from Karolinska Institutet in Sweden finds that testing for human papilloma virus (HPV) allows for longer time between screening tests when compared to cytology-based testing. The study is published in the scientific journal British Medical Journal (BMJ).
Cervical screening progra... Read More
Saint Cloud, Minnesota, USA (July 8, 2014) Microbiologics, Inc., a leading global manufacturer of ready-to-use biological controls and standards, has partnered with Biomatrica, Inc., a world leader in ambient temperature stabilization of biomaterials. Microbiologics has licensed Biomatrica’s DNA... Read More
A pervasive fungus, passed along by pigeon droppings, can kill HIV patients by using a Trojan Horse strategy to invade their brains. Pigeon droppings and vulnerable immune systems can be a deadly combination. Fortunately, scientists are starting to figure out how different strains of a yeast tha... Read More
JOHANNESBURG, 2 April 2014 (IRIN) - Outbreaks of a deadly fungal disease in wheat crops in Germany and Ethiopia in 2013 have had the scientific community buzzing over the threat posed to global food security. Wheat stem rust, also known as wheat black rust, is often referred to as the “polio of... Read More
In this blog entry, I describe how working with the artist Katie McKissick ("Beatrice the Biologist") helped improve my freshman biology course. The intersection of biology and art benefits both! Read More
The Lassa virus, endemic to West Africa, uses an unexpected two-step process to enter cells, research has shown. The results suggest that the mechanism by which Lassa virus causes infection is more complicated than previously known, and could lead to new approaches for preventing the disease.

A new genetic analysis revealing the previously unknown biodiversity and distribution of thousands of fungi in North America might also reveal a previously underappreciated contributor to climate change. Pine forests are chock full of wild animals and plant life, but there's an invisible machine... Read More
Nutrient enrichment and climate change are posing yet another concern of growing importance – an apparent increase in the toxicity of some algal blooms in freshwater lakes and estuaries around the world, which threatens aquatic organisms, ecosystem health and human drinking water safety.
As t... Read More
On a molecular level, you have more in common with shower curtain mold or the mushrooms on your pizza than you might think. Humans and fungi share similar proteins, a biological bond that makes curing fungal infections difficult and expensive. Current costs to treat these stubborn infections can... Read More
Researchers at the University of Melbourne have discovered that some Indigenous groups will be more susceptible to the effects of the new strain of influenza (H7N9) currently found in China.
Research indicated that some Indigenous people such as in Alaska and Australia displayed limited immun... Read More
If you think books are old tech, you may be dismissing them too soon. The latest application for the folio design is a collection of water filters that are long-lasting and also provide information about consuming unsafe water. The humanitarian group WaterisLife and the ad agency DDB have teamed... Read More
