The sprawling citrus orchard that Victor Story toured recently sure looked like a steal at $11,000 an acre. The investors who owned it were going to lose money, and potential buyers such as Story might have stood to reap a handsome reward.
But as he bumped along the 40 acres of groves in a la... Read More
In Pakistan prevalence and drug resistance of TB is on the rise. Late diagnosis and lack of resources are making the situation worse. In such a scenario molecular techniques such as PCR and hybridization would help in early diagnosis of TB and MDR TB leading to commencement of treatment at the r... Read More
Inspired by natural materials such as bone — a matrix of minerals and other substances, including living cells — MIT engineers have coaxed bacterial cells to produce biofilms that can incorporate nonliving materials, such as gold nanoparticles and quantum dots.
These “living materials” combin... Read More
For scientists tracking the deadly Ebola virus in West Africa, it is not about complex virology and genotyping, but about how contagious microbes - like humans - use planes, bikes and taxis to spread.
So far, authorities have taken no action to limit international travel in the region. The ai... Read More
Researchers at Bigelow Laboratory for Ocean Sciences dug into the last 70 years of peer-reviewed publications about protozoan parasites that infest bivalve mollusks and found that when an organism can be cultured in the laboratory, more papers and greater understanding result. Senior Research S... Read More
A boy with cystic fibrosis develops a chronic and potentially deadly Burkholderia dolosa infection in his lungs. Varieties of genetic mutations allow some strains of the bacteria to survive the dual assaults from his immune system and antibiotics, while others perish. Eventually, the strongest m... Read More
Researchers have identified the evolutionary origins of human herpes simplex virus (HSV) -1 and -2, reporting that the former infected hominids before their evolutionary split from chimpanzees 6 million years ago while the latter jumped from ancient chimpanzees to ancestors of modern humans -- H...

Whooping cough was once one of the leading killers of babies around the world. Now that it's largely controlled with a vaccine, scientists have had a chance to figure out how the disease came into being in the first place. That story is told in a study published online this week in the journal m... Read More
Partial isolate of an unknown organism on trypticase soy agar exhibiting spreading and mounding in an irregular-rhizoid form with lobate margins. The colony exhibited an opaque yellow-orange pigment with a mucoid surface. This sample was obtained from a floor swab and incubated at 37°C. Read More
Partial isolate of an unknown organism on trypticase soy agar exhibiting spreading and an irregular-rhizoid form with lobate margins. The pigment is opaque white-beige with a mucoid surface over most of the colony. A dry, dull, matte surface appears toward the outer edges of the colony. The s... Read More
Two months after safety breaches at federal labs first set off a public furor, top health officials are auditioning new checks on worker safety including specialized time-lapse cameras and digital worksheets to track crucial steps such as bacterium inactivation. The goal: to prevent future debac... Read More
Scientists regularly tap into biological systems to find solutions for human problems. Although they work with plants and viruses in the lab, bacteria have many advantages as a starting point. When programmed in certain ways, bacteria can store data, clean dangerous waste, produce film-like imag... Read More
Using an experimental technique new to the dengue field, the labs of Ralph Baric, PhD, and Aravinda de Silva, PhD, showed that a molecular hinge where two regions of a protein connect is where natural human antibodies attach to dengue 3 to disable it. The finding, published in the Proceedings of... Read More
Low birth weight infants are host to numerous microorganisms immediately after birth, and the microbiomes of their mouths and gut start out very similar but differentiate significantly by day 15 according to a study in mBio this week. Researchers from Stanford University and the University of Pi... Read More
Methicillin-resistant S. aureus (MRSA) constitutes approximately 50% of clinical S. aureus isolates and is most commonly the result of production of a mutated pencillin-binding protein, PBP2a, which is able to carry out essential cell wall synthesis functions while maintaining a low-affinity for...

Banana lovers take note: The world's supply of the fruit is under attack from a fungus strain that could wipe out the popular variety that Americans eat. "It's a very serious situation," said Randy Ploetz, a professor of plant pathology at the University of Florida who in 1989 originally discove... Read More
According to CNN,a long-range business jet with an isolation pod left the United States for Liberia, where it will evacuate two Americans infected with Ebola.
Twitter exploded with questions about the deadly virus, which according to the World Health Organization is believed to have killed hu... Read More
The instructions encoded into DNA are thought to follow a universal set of rules across all domains of life. But researchers report in the May 23 issue of Science that organisms routinely break these rules.
The finding has implications for the design of synthetic life: by designing organisms ... Read More
