Ice, Ice, Bacteria (Not Too Cold)

Bacterial proteins could alter precipitation patterns and climate-change models.

Proteins can help grow teeth and bones in the body, crops in the ground, and even ice in the atmosphere. Some proteins have an uncanny knack for kick starting ice formation at unusual temperatures, and they have ... Read More

A Key Step Toward a Safer Strep Vaccine

An international team of scientists, led by researchers at the University of California, San Diego School of Medicine, have identified the genes encoding a molecule that famously defines Group A Streptococcus (strep), a pathogenic bacterial species responsible for more than 700 million infection...

Nanocrystalline cellulose modified into an efficient viral inhibitor

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

We Are Not Alone: How the Human "Planet" Is Colonized (video)

The gut microbiome is an emerging field that has been linked to many diseases and conditions affecting each and everyone of us from metabolism to potential neurological diseases.

MRSA declines are sustained in veterans hospitals nationwide

Five years after implementing a national initiative to reduce methicillin-resistant Staphylococcus aureus (MRSA) rates in Veterans Affairs (VA) medical centers, MRSA cases have continued to decline, according to a study in the November issue of the American Journal of Infection Control, the offi...

Guo Lab Reports Finding of Revolution Biomotors in Many Bacteria and Viruses

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

Microbiologics Partners with Biomatrica to Provide Biological Stabilizers for Their Line of Molecular Standards

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

Likely origin of lung fungus invading Pacific Northwest found by study

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

Influenza A viruses in bats

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

How deadly lassa virus infects cells

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.

Longer Screening Intervals Possible With HPV-Based Tests

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

Mutant wheat fungus alarms food experts

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

How Weak Immune Systems Escort a Deadly Fungus Into the Brain

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

Where Biology and Art Work Together in the Classroom

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

Stanford biologists help solve fungi mysteries

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

Indigenous groups more vulnerable in the fight against flu

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

Increasing toxicity of algal blooms tied to nutrient enrichment and climate change

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

New Drug Candidate Found for Fungal Lung Infections

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

U.S. flu activity low, but Los Angeles confirms a women died

U.S. influenza activity remains low, but Los Angeles County confirmed its first death -- a woman with an underlying medical condition, an official says.

Dr. Jonathan E. Fielding, director of public health and health officer, says the woman resided in the San Fernando Valley and the particular... Read More
