Molecule hijacks enzyme to boost alcohol metabolism

An experimental compound empowers an enzyme to help process acetaldehyde, a toxic metabolite of alcohol, according to new research supported by the National Institute on Alcohol Abuse and Alcoholism (NIAAA). The findings, now online in the Proceedings of the National Academy of Sciences (PNAS), ... Read More

Genome sequencing traces MRSA spread in high transmission setting

Methicillin-resistant Staphylococcus aureus is a common cause of hospital-acquired infections, with the largest burden of infections occurring in under-resourced hospitals. While genome sequencing has previously been applied in well-resourced clinical settings to track the spread of MRSA, transm... Read More

How llamas' unusual antibodies might help in the fight against HIV/AIDS

Most vaccines work by inducing an immune response characterized by neutralizing antibodies against the respective pathogen. An effective HIV vaccine has remained elusive so far, but researchers have continued to make progress, often employing innovative methods. A new study reports that a combin... Read More

Cells ‘feel’ their surroundings using finger-like structures

Cells have finger-like projections that they use to feel their surroundings. They can detect the chemical environment and they can ‘feel’ their physical surroundings using ultrasensitive sensors. New research from the Niels Bohr Institute shows how the finger-like structures, called filopodia ca... Read More

Discovery in the fight against antibiotic-resistant bacteria

For four years, researchers at Universite catholique de Louvain have been trying to find out how bacteria can withstand antibiotics, so as to be able to attack them more effectively. These researchers now understand how one defense mechanism works and the results of their research have been publ... Read More

Infectious disease: Mobilizing Ebola survivors to curb the epidemic

Multiple governments and non-governmental organizations have called on health-care personnel the world over to help control West Africa's Ebola outbreak; these include Médecins Sans Frontières (MSF), the World Health Organization (WHO) and United Nations children's charity UNICEF. But the demand... Read More

New age of genome editing could lead to cure for sickle cell anemia

UNSW Australia researchers have shown that changing just a single letter of the DNA of human red blood cells in the laboratory increases their production of oxygen-carrying haemoglobin - a world-first advance that could lead to a cure for sickle cell anaemia and other blood disorders. Read More

Bacteria ‘factories’ churn out valuable chemicals

A team of researchers led by Harvard geneticist George Church at the Wyss Institute for Biologically Inspired Engineering and Harvard Medical School (HMS) has made big strides toward a future in which the predominant chemical factories of the world are colonies of genetically engineered bacteria...

Unknown Fungal Contaminant

Unknown fungal contaminant, presumably airborne, found on TSA after several months at refrigerated temperatures. Brown spore formation was seen in the middle of the colony with whit hyaphae at the edges. Colony was approximatly 1/4 of the plate. Read More

Life would go on if all bacteria disappeared

Microbes: They're everywhere, including inside our bodies. But are they really necessary? Not to life, scientists argue in a new paper — but certainly to life as we know it.

For starters, microbiologists Jack Gilbert and Josh Neufeld had to put aside the internal cell structures that were pro... Read More

Life on a Pig's Skin

How frequently do microbes exchange genes when living on a host? This question has been on my mind lately. Broadly speaking, the discovery of horizontal gene transfer (HGT) revolutionized the way we think about prokaryotic evolution. No more could we think only of inheritance via vertical descen...

Ebola Survivor: The Best Word For The Virus Is 'Aggression'

When Dr. Ian Crozier arrived in West Africa this past summer, he was stepping into the epicenter of the Ebola hot zone. The American doctor was working in the Ebola ward of a large, public hospital in Sierra Leone's dusty city of Kenema.

The trip nearly cost him his life. First came a fever, ... Read More

New study offers novel insights into pathogen behavior

A new study by a team of researchers that includes University of Notre Dame scientists Joshua Shrout and Mark Alber provides new insights into the behavior of an important bacterial pathogen.

Bacterial Motors Come in a Dizzying Array of Models

Bacteria that can swim propel themselves with corkscrew tails anchored in rotary motors. That may seem surprisingly mechanical for a microbe, but it is a system that has been wildly popular and conserved across billions of years of evolution.

To see what I mean, I encourage you to visit this ... Read More
