Soil bacterium causes biofuel breakdown

Biofuels made from plant materials—also known as lignocellulosic biofuels—have promise as a source of sustainable alternative fuels thanks to soil bacterium known as Enterobacter lignolyticus SCF1. SCF1 degrades lignin and decomposes plant cell walls, allowing access to the cellulose sugars that... Read More

Bacteria swim with bodies and flagella

Using a new technique to track the swimming motion of a single bacterium, researchers have discovered that the movement of the bacterium’s body — not just thrust from the flagellum — allow movement through fluids. The finding could shed new light on the evolution of cell body shape.

Researchers open door to new HIV therapy

BERKELEY — People infected with the Human Immunodeficiency Virus (HIV) can stave off the symptoms of AIDS thanks to drug cocktails that mainly target three enzymes produced by the virus, but resistant strains pop up periodically that threaten to thwart these drug combos. Researchers at the Unive... Read More

Warmer temperatures push malaria to higher elevations

Researchers have debated for more than two decades the likely impacts, if any, of global warming on the worldwide incidence of malaria, a mosquito-borne disease that infects more than 300 million people each year. University of Michigan ecologists and their colleagues are reporting the first har... Read More

WHO warns against 'post-antibiotic' era

The 'post-antibiotic' era is near, according to a report released today by the World Health Organization (WHO). The decreasing effectiveness of antibiotics and other antimicrobial agents is a global problem, and a surveillance system should be established to monitor it, the group says. There is ... Read More

E. coli Keeps Its Powder Dry

Whether inhabiting soil, fresh water, or marine ecosystems, bacteria are constantly facing the threat of numerous and effective predators such as protists, nematodes, or phages. To defend against such predation, bacteria have evolved a number of strategies, including getting larger in size, movi... Read More

Engineers design ‘living materials’ - Hybrid materials combine bacterial cells with nonliving elements that can conduct electricity or emit light

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

Stealth tactics of bacteria revealed

WE ARE now privy to the ways bacteria outsmart antibiotics, thanks to a technique which measures the evolution of antibiotic resistance.

A team led by Erdal Toprak and Adrian Veres at Harvard University developed the "morbidostat", a device that constantly monitors the growth of bacteria in t... Read More

Recalling the Good in the Good Old Days

In its early days, ca. 1945-1965, molecular biology was a particularly collegial undertaking, characterized by free sharing of research data and a relative lack of egotistical behavior. The reason for this marvel may well have been that there was so much to discover—so many low hanging fruits—th... Read More

Florida citrus growers worry that deadly bacteria will mean end of orange juice

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

Self-Assembly For Me

I have the grating feeling that the subject of self-assembly of complex biological structures may not always amass the level of respect it deserves. I reckon that its importance is generally appreciated but, as topics go, it tends at times to be set aside. Yet, this is one of the most magnificen... Read More

Bacteria show surprising number of genetic paths to survival

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

Scientists Convert Bacteria from Free-living to Nitrogen Fixing

If you pull up a soybean or bean plant and shake off the dirt, you might see odd swellings or bumps, like rheumatic finger joints, on its roots. Inside the cool, soil-covered bumps are bacteria that are making nitrogen with the help of an enzyme, something chemical factories can do only with the... Read More

Family Tree Of Pertussis Traced, Could Lead To Better Vaccine

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

Mollusk parasite culturing methods drive research

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

Herpes infected humans before they were human

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...

Researchers Unlock the Genetic Code of Cancer-Causing Liver Fluke Parasite

An international team of scientists from Singapore, Thailand, China and Australia has cracked the genetic code of the liver fluke parasite, Opisthorchis viverrini, using a unique DNA analysis technique developed at A*STAR’s Genome Institute of Singapore (GIS).

GIS’s DNA analysis technique ha... Read More

Taxis, Planes and Viruses: How Deadly Ebola Can Spread

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

Imaging combo spots infection in 3D

Scientists have combined MRI and imaging mass spectrometry to visualize the body’s inflammatory response to a bacterial infection in 3D. The techniques, described in Cell Host & Microbe, offer opportunities for discovering proteins not previously implicated in the inflammatory response.

Hacking Bacteria To Do Our Bidding: Photos

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
