By introducing DNA from other organisms, scientists enhance production of compounds in fungus

The enzymes and compounds produced by fungi are of great interest to the pharmaceutical, textile, paper and food industries. These organisms are capable of secreting, their nutritional needs are low and have high growth rate. A group of researchers from the National Autonomous University of Mexi... Read More

Scientists find superbug bacteria in World War I soldier who died of dysentery

Scientists who unlocked the genetic code of bacteria grown from a soldier who died of dysentery say it revealed a superbug that was resistant to antibiotics decades before those drugs were in common use.

The discovery sheds light on the history of antibiotic resistance, which has become a glo... Read More

Students aim to put cyanobacteria on Mars to generate oxygen

Mars is a very harsh and hostile environment for future human explorers and like any other known planet it has no breathable air. That could change someday, and it may be soon enough for our generation to witness it, as the student team from Germany has a bold vision to make a first step to terr... Read More

Discovery aims to fight destructive bee disease

Researchers hope their new discovery will help combat a disease killing honeybee populations around the world. The researchers have found a toxin released by the pathogen that causes American foulbrood disease -- Paenibacillus larvae -- and developed a lead-based inhibitor against it.

Millions of Doses of Ebola Vaccine to Be Ready by End of 2015

The World Health Organization (WHO) announced plans on October 24 to produce millions of doses of two experimental Ebola vaccines by the end of 2015.

Hundreds of thousands of doses should be available to help affected countries before the end of June, the WHO said at the conclusion of a meeti... Read More

All the microbes of the field will clap their hands

I’ve said it before and I’ll say it again: microbes are everywhere, and everywhere important. As regular readers will know, I’ve recently become obsessed with cultivating our microbial companions to make delicious foods. But you don’t have to have to constantly minding jars of kraut or jugs of m... Read More

Plant Pathogen Silences Host’s Immune Genes

As more and more information becomes available, one marvels (and also frets) at the sophisticated strategies that pathogens have evolved in order to evade their hosts’ defense mechanisms. Many pathogens of plants and animals deliver effectors into their hosts in order to suppress immune response... Read More

Nanotechnology Against Malaria Parasites

Malaria parasites invade human red blood cells, they then disrupt them and infect others. Researchers at the University of Basel and the Swiss Tropical and Public Health Institute have now developed so-called nanomimics of host cell membranes that trick the parasites. This could lead to novel tr... Read More

A Snippet: Thioploca

The seafloor off the coast of Chile is carpeted with bacterial mats of gigantic proportions. They cover an area as large as that of the state of Alabama. Their total weight is of the order of 100 million tons, which probably makes this the largest single species microbiome on Earth. The mats con... Read More

How Did Nigeria Quash Its Ebola Outbreak So Quickly?

On July 20 a man who was ill flew on commercial planes from the heart of the Ebola epidemic in Liberia to Lagos, Nigeria's largest city. That man became Nigeria's first Ebola case—the index patient. In a matter of weeks some 19 people across two states were diagnosed with the disease (with one a... Read More

First detailed microscopy evidence of bacteria at the lower size limit of life

Scientists have captured the first detailed microscopy images of ultra-small bacteria that are believed to be about as small as life can get. The existence of ultra-small bacteria has been debated for two decades, but there hasn't been a comprehensive electron microscopy and DNA-based descriptio... Read More

Battling superbugs

Two new technologies could enable novel strategies for combating drug-resistant bacteria.

In recent years, new strains of bacteria have emerged that resist even the most powerful antibiotics. Each year, these superbugs, including drug-resistant forms of tuberculosis and staphylococcus, infect... Read More

Epidemiological Study by Penn Vet Professor Investigates Parasite-Schizophrenia Connection

Many factors, both genetic and environmental, have been blamed for increasing the risk of a diagnosis of schizophrenia. Some, such as a family history of schizophrenia, are widely accepted. Others, such as infection with Toxoplasma gondii, a parasite transmitted by soil, undercooked meat and cat... Read More

Five Questions About the Foraminifera

The Foraminifera ("forams") are among the largest and most abundant of all unicellular organisms. They can reach 20 cm in length and 18 cm in width, and the shells surrounding them are even bigger, up to 30 cm in length. They have existed in prodigious numbers that the remnants of their shells h... Read More

Pictures Considered #21. Southern Blot

"... These results, gained with a novel method for blotting (E. M. Southern, manuscript in preparation), have also led to the identification of the Bam Hl recognition sequence". It is rather unusual to find unpublished work referred to in the abstract of a paper, to put it mildly. But this was e... Read More

A “Polio Warrior” Recounts Decades of Struggle Toward Eradication

Science writer Maryn McKenna interviews John Sever, MD, PhD, former chief of infectious diseases at the National Institutes of Health and current vice-chairman of Rotary’s International PolioPlus Committee, about the early days of the polio struggle and the introduction of the polio vaccine.

Injectable 3D vaccines could fight cancer and infectious diseases

New findings show programmable biomaterials can be delivered using needle injection to induce an immune response and fight deadly diseases.

One of the reasons cancer is so deadly is that it can evade attack from the body's immune system, which allows tumors to flourish and spread. Scientists ... Read More
