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
This is our first ever recommendation of an article published outside the usual scientific venues, but after all the hype we have heard about the human microbiome we were delighted to finally read a balanced account of what the research tells us and what it does not tell us. Plus, this article w... Read More
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
Genetic factors could play an important role in whether people survive the Ebola virus, say US scientists.
A study of mice infected with the virus found they showed a number of different symptoms, with 19% remaining unaffected by the disease.
This could explain why some people recover from... Read More
Though horizontal gene transfer (HGT) is widespread, genes and taxa experience biased rates of transferability. Curiously, independent transmission of homologous DNA to archaea, bacteria, eukaryotes, and viruses is extremely rare and often defies ecological and functional explanations. Here, we ... Read More
For many bacteria and parasites looking to get a load of the fresh nutritional bounty inside your body, the skin is the first and most important gatekeeper. Schistosomas, however, and burrow right on through. These waterborne blood flukes, responsible for 200 million total worldwide cases of Sch... Read More
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
As will be argued below the present definition of a prokaryote is highly unsatisfactory. To give an example: a prokaryote is "a cell or organism lacking a nucleus and other membrane-enclose organelles, usually having its DNA in a single circular molecule" (Brock, Biology of Microorganisms, 10th ...

While Hollywood loves to imagine humans encountering all manner of horrific monsters in the depths of space, the greatest threat to a long-term, manned space mission may not come with tentacles, or extra mouths, or an insatiable love for human flesh. It may, in fact, be the invisible microbes t... Read More
"... 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 Japanese mushroom extract appears to be effective for the eradication of human papillomavirus (HPV), according to a pilot clinical trial at The University of Texas Health Science Center at Houston (UTHealth) Medical School.
The results were presented at the 11th International Conference of ... Read More
In research published in Nature Chemical Biology, scientists from RIKEN in Japan have discovered a surprisingly simple mechanism through which enterics can adjust to the very different oxygen environments inside the human gut and outside. This research, which was led by Shigeyuki Yokoyama and Wa... Read More
Where does HIV hide? Antiretroviral drugs can usually control the virus, but can’t completely eliminate it. So any strategy to eradicate HIV from the body has to take into account not only the main group of immune cells the virus targets, called CD4 or helper T cells, but other infected cells as...

People who carry a particular type of gene have natural resistance against typhoid fever according to new research published in Nature Genetics.
Lead researcher, Dr Sarah Dunstan from the Nossal Institute of Global Health at the University of Melbourne said the study is the first large-scale,... Read More
Companies selling ‘probiotic’ foods have long claimed that cultivating the right gut bacteria can benefit mental well-being, but neuroscientists have generally been sceptical. Now there is hard evidence linking conditions such as autism and depression to the gut’s microbial residents, known as t... Read More
Researchers at Washington University School of Medicine in St. Louis have sequenced the genome of enterovirus D68 sampled from patients treated at St. Louis Children’s Hospital. Nationwide, the virus has spread rapidly in recent months and caused severe respiratory illness in young children, wit... Read More
A novel method of altering a protein in milk to bind with an antiretroviral drug promises to greatly improve treatment for infants and young children suffering from HIV/AIDS, according to a researcher in Penn State's College of Agricultural Sciences.
That's critical because an estimated 3.4 m... Read More
New research shows how disruption of human biological clock can have negative impact on human intestinal micobiome and in turn lead to metabolic dysfunctions such as weight gain and diabetes. Read More
Researchers have made great progress in recent years in the design and creation of biological circuits — systems that, like electronic circuits, can take a number of different inputs and deliver a particular kind of output. But while individual components of such biological circuits can have pre... Read More
While an Ebola epidemic has been raging in West Africa since March 2014, an outbreak of this haemorrhagic fever occurred in the Democratic Republic of the Congo (DRC) in August, leaving fears over the virus' spread to Central Africa. A study by the IRD, the Institut Pasteur, the CNRS, the CIRMF... Read More
