Researchers at The University of Texas at Dallas (UTD), led by Dr. Lee Bulla, have demonstrated for the first time the selective cytotoxicity of Bacillus thuringiensis subsp. israelensis Cry4B toxin is mediated by BT-R3.
The Cry toxins produced by Bacillus thuringiensis exert their insecticid... Read More
Quick, which is the biggest symbiotic association on Earth? Did you guess the mycorrhizae? They are the huge symbioses between fungi and the roots of most terrestrial plants. Their total size is not easy to measure because not all the fungal filaments in soils are mycorrhizal nor are the mycorrh... Read More
What is wrong with this paragraph from today’s New York Times that describes the origin of the Middle East Respiratory Syndrome (MERS) coronavirus:
Health officials confirmed Wednesday that bats in Saudi Arabia were the source of the mysterious virus that has sickened 96 people in the Middle ... Read More
A clinical trial of an innovative vaccine is occurring. The vaccine could offer hope to patients with advanced ovarian cancer. The vaccine, which is derived from the patient's tumor cells, is designed to jumpstart the patient's immune system to attack and kill cancer cells.
Ovarian cancer is ... Read More
A deadly new bird flu virus in China evolved from migratory birds via waterfowl to poultry and into people, and there are other bird flu viruses circulating that could follow the same path, scientists have found.
The study - an analysis of the evolutionary history of the H7N9 bird flu that ha... Read More
By throwing together a common fungus and a common bacteria, researchers are producing isobutanol — a biofuel that gallon-for-gallon delivers 82 percent of gasoline’s heat energy. The more common ethanol, by contrast, only gets 67 percent of gasoline’s energy, and does more damage to pipelines an... Read More
Females can mount more powerful immune responses than males, but the flip side of this enhanced protection against infections is a greater risk for autoimmune disorders. Shedding light on the underlying causes of the gender bias in autoimmune diseases, a study published by Cell Press August 22nd... Read More
Gut bacteria exert a dramatic, systemic effect on the development of the immune system's B-lymphocytes, according to a new mouse study by researchers at Boston Children's Hospital. While influences of gut bacteria on T-lymphocytes have been noted before, this is the first time that researchers h... Read More
In this post from my blog, I discuss the recent interest in snarky-funny academic hashtags on Twitter, such as #overlyhonestsyllabi. Just like students, educators need to blow off some steam (especially as classes approach!). But it is also important to remember our educational goals, and matc... Read More
The U.S. Food and Drug Administration today allowed marketing in the U.S. of the first mass spectrometer system for automated identification of bacteria and yeasts that are known to cause serious illness in humans. The VITEK MS can identify 193 different microorganisms and can perform up to 192 ... Read More
A Michigan State University scientist will use a $1.9 million grant from the National Science Foundation and the Biotechnology and Biological Sciences Research Council (United Kingdom) to solve the mystery of the missing bacteria.
The bacteria, discovered in a German charcoal pit in the 1990s, ... Read More
Dr. Jeffrey Almond began his career as an academic virologist studying influenza. Eventually Jeffrey started his own lab and began studying picornaviruses working on an oral polio vaccine strain.
Following twenty ... Read More
A hospital was fined after a pair of neurosurgeons implanted fecal bacteria into the brains of patients during operations without proper authorization. A few things jump out at us here. 1) They did WHAT!?! 2) There’s proper authorization for putting poop in people’s brains!?! 3) Ewwwwwww.
The... Read More
Nothing gets our attention like pain.
But pain is more than the body’s miniature cattle prod to get us to heed a wound, rest a swollen ankle, or stop eating chili peppers. Pain may be the language between animals and microbes.
Far from being a product of an inflamed immune system, aggravat... Read More
Recent conflicts in Egypt, Iraq, Libya, Pakistan, Syria, Tunisia, Yemen, and elsewhere in the Middle East may have sufficiently destabilised national and international public health control measures to a point where several tropical diseases have either emerged and are sickening large population...

A new hypothesis concerning a crucial step in the anthrax infection process has been advanced by scientists at the National Institute of Standards and Technology (NIST) and the U.S. Army Medical Research Institute for Infectious Diseases (USAMRIID) at Fort Detrick, Md.
The research teams have... Read More
Infection during a newborn's first 7 days of life is associated with bacterial infection or colonization in the mother. Early-onset neonatal infection, defined as infection in the first 7 days of life, is associated with maternal infection and colonization, a systematic review and meta-analysis ... Read More
