Scientists learn how to ramp up microbes' ability to make memories

Some microbes can form memories—although, inconveniently for scientists who study the process, they don’t do it very often.

Rockefeller University researchers and their colleagues at the University of California, Berkeley, have found a way to make bacteria encode memories much more frequently... Read More

Protein that activates immune response harms body's ability to fight HIV

n findings they call counterintuitive, a team of UCLA-led researchers suggests that blocking a protein, which is crucial to initiating the immune response against viral infections, may actually help combat HIV.

Findings from a study in animals appear to demonstrate that temporarily blocking a... Read More

Yum! Digesting ASM Resources for Food Microbiology

Food-related microbiology can be one of the most fun - or least fun - ways to interact with microbes. In the ‘most fun’ category, scientists and non-scientists alike can use microbes to create delicious foods from fermentative processes; in the ‘least fun’ category, scientists and non-scientists...

White House Goes With Its Gut, Backs New Microbiome Project

The White House wants to encourage research into the microbiome: the microbes living in and on animals, the dirt, oceans and the atmosphere.

The White House says it will propose more than $121 million in federal spending over the next two years at the Department of Energy, NASA, National Inst... Read More

Mouse microbes may make scientific studies harder to replicate

The microbes that reside in mice are making it difficult to replicate scientific studies. Despite many researchers best efforts to standardize the environment and conditions that their mice live in, replication isn't always possible. While "cagemates" tend to have the same microbes in their gut,... Read More

Creating a slippery slope on the surface of medical implants

Implanted medical devices such as left ventricular-assist devices for patients with heart failure or other support systems for patients with respiratory, liver or other end organ disease save lives every day. However, bacteria that form infectious biofilms on those devices, called device-associa... Read More

Summer Travel and the Zika Virus #rio2016

Health officials have warned pregnant women to avoid travel to the more than 45 countries and territories in which the Zika virus is circulating. Infection during pregnancy can lead to birth defects in infants, particularly brain damage and abnormally small heads, called microcephaly.

But wit... Read More

Temple scientists eliminate HIV-1 from genome of human T-Cells

(Philadelphia, PA) - A specialized gene editing system designed by scientists at the Lewis Katz School of Medicine at Temple University is paving the way to an eventual cure for patients infected with HIV, the virus that causes AIDS. In a study published online this month in the Nature journal, ... Read More

Molecular Analysis and Expression of bap Gene in Biofilm-Forming Multi-Drug-Resistant Acinetobacter baumannii. Reports of Biochemistry & Molecular Biology 2016

Abstract

Background: Acinetobacter baumannii is commonly resistant to nearly all antibiotics due to presence of antibiotic resistance genes and biofilm formation. In this study we determined the presence of certain antibiotic-resistance genes associated with biofilm production and the influen... Read More

TWiV 417: O is the loneliest letter

The Fellowship of the Virus trace the early history of HIV in North America, based on genome sequences obtained from late 1970s archival sera, which also reveal that Gaetan Dugas was not Patient Zero.

Zika May Harm Male Reproduction

he Zika virus attacks cells in mouse testes crucial for sperm and sex hormone generation and hampers reproduction, according to new research that raises the possibility that the virus could affect fertility in men.

And even if the same outcomes bear out in people, researchers have no idea wha... Read More

Genomic sequencing illuminates recent Shigella outbreaks in California

In a study that could have significant impact on how disease outbreaks are managed, researchers at UC Davis and the California Department of Public Health (CDPH) have sequenced and analyzed genomes from Shigella sonnei (S. sonnei) bacteria associated with major shigellosis outbreaks in Californi...

Natural predatory bacteria could combat drug resistance problem

While bacteria have been evolving for 3.5 billion years, mammals have evolved with bacteria for only 2.5 million years. Thus, it's not that surprising that humans appear to be losing the war on antibiotic resistance.
The issue of multidrug-resistance and the lack of antibiotics in the developme... Read More

Electron microscopy captures snapshot of structure coronaviruses use to enter cells

High-resolution cryo-electron microscopy and supercomputing have now made it possible to analyze in detail the infection mechanisms of coronaviruses. These viruses are notorious for attacking the respiratory tract of humans and animals. Read More

Why attend ABRCMS? Students discuss their experiences

Students are the focus of the Annual Biomedical Research Conference for Minority Students (ABRCMS) meeting, held most recently November 9-12, 2016, in Tampa, Florida. Undergraduate and postbaccalaureate students make up over half the roughly 4,000 program participants, and many participants belo... Read More

Feed a cold, starve a fever? Not so fast, according to Salk research

The last time you had a stomach bug, you probably didn’t feel much like eating. This loss of appetite is part of your body’s normal response to an illness but is not well understood. Sometimes eating less during illness promotes a faster recovery, but other times—such as when cancer patients exp... Read More
