People have been wondering where the Gulf of Mexico oil has gone. Some years ago our friend Dr Banwari Lal from TERI New Delhi has been working on some microorganisms that degrade the oil by eating it or metabolizing it . Perhaps , there could be attack by such bacteria or microorganisms which have eaten or metabolized the Gulf oil. It would be interest to confirm or refute this theory so tha we are better prepared for future happenings. If you will ride the horse so will you fall also. So better be prepared.
The existence of multicellular organisms, the first complex life forms (made up of several cells) has been extended from about 600 million years in the past to over 2 billion years ago, according to research published in Nature.
That means organized life is a lot older than was scientifically accepted, though older existence was obviously assumed because the first traces of life appeared in the form of prokaryotic organisms (without a nucleus) 3.5 billion years ago. The "Cambrian explosion" 600 million years ago marked a proliferation in the number of living species and was…

Abstract: Four types of DNA stains were evaluated based on safety, ease of use, cost, and resolution. Ethidium Bromide was tested primarily as a comparison to the standard stain normally used in education, industry, and research. While price is higher with the safer safe stains both FastBlast from Bio-Rad and Sybr Safe from Molecular Probes were found to have good resolution and be almost as easy to use as Ethidium Bromide without the toxicity and mutagen dangers.Introduction: A large number of accidents occur every year involving chemical release in secondary schools.…
Each day the humans are confronted with a variety of pathogens. Most of them are fended off by our immune system.
For a successful infection, bacteria must deliver so-called virulence factors through a transport channel located in the bacterial membrane. Scientists from the Max Planck Society and the Federal Institute for Materials Research and Testing have shown how in some bacteria this transport channel is formed like a syringe, enabling them to inject virulence factors directly into the host cell - an important starting point for the development of new drugs that might…
A new strain of bacteria can produce non-toxic, comparatively inexpensive rhamnolipids and effectively help degrade polycyclic aromatic hydrocarbons, or PAHs – the environmental pollutants that are one of the most harmful aspects of oil spills.
The findings on this new bacterial strain, NY3, of a common bacteria that has been known of for decades, called Pseudomonas aeruginosa, that degrades the PAHs in oil and other hydrocarbons were just published in Biotechnology Advances by researchers from Oregon State University and two collaborating universities in China. Because of some…
I have come to believe that science has abandoned its viability and veracity. For example, we can make microcameras and artificial organs but micro technology to fight things like viruses and bacterial infections is not being explored. The Sciences need to worry less about profit and more about being solid and moral gate keepers. There is a fload of information that could be maintained if the micro technology was being used ethically. Please talk!

A bacterial pathogen can communicate with yeast to block the development of drug-resistant yeast infections according to Irish scientists writing in the May issue of Microbiology. The research could be a step towards new strategies to prevent hospital-acquired infections associated with medical implants.
Researchers from University College Cork in Ireland studied the interaction between the bacterium Pseudomonas aeruginosa, a gram negative, rod shaped bacterium which is often associated with severe burns, and the yeast Candida albicans that is the causative agent of Candidiasis, also…
Researchers from the University of Gothenburg have discovered a brand new species of bacterium found only in the Gullmarsfjord north of Gothenburg in Sweden. The new species has been dubbed Endoxenoturbella lovénii.
The bacterium is an endosymbiotic prokaryote living in the gut of a marine worm called Xenoturbella, a creature also unique to the Gullmarsfjord. Researchers identified two types of endosymbiotic bacteria (Xenoturbellida, Bilateria). They say other scientists should consider the new endosymbionts "when interpreting the poorly understood ecology and evolution of Xenoturbella…

I once read that "age doesn't matter, unless you're a cheese." This somewhat comical phrase is referring to the process of cheese production where various milks, depending on the type of cheese, are coagulated to concentrate specific proteins and fats that makeup the final dairy food product. Specifically it is saying that, like many wines, most cheeses improve in terms of flavor enhancement the longer they age.
An article by Greek authors Dimitra Dimitrelloua, Panagiotis Kandylis et al. asks if freeze dried kefir is a beneficial starter to use in this process…
