New insights into a surprisingly flexible immune system present in bacteria for combating viruses and other foreign DNA invaders have been revealed by researchers from the University of Otago and the Netherlands.
A team led by Dr Peter Fineran of the Department of Microbiology and Immunology ... Read More
We’re in the midst of an extinction crisis, and it doesn’t involve Siberian tigers. Microbiologist Martin Blaser of New York University School of Medicine says that many species of germs are disappearing from our bodies—and that’s a problem. In his new book, Missing Microbes: How the Overuse of ... Read More
The Foldscope is a fully functional microscope that can be laser- or die-cut out of paper for around 50 cents.
This bookmark-sized microscope can be assembled in minutes, includes no mechanical moving parts, packs in a flat configuration, is extremely rugged and can be incinerated after to s... Read More
Programming living cells offers the prospect of harnessing sophisticated biological machinery for transformative applications in energy, agriculture, water remediation and medicine. Inspired by engineering, researchers in the emerging field of synthetic biology have designed a tool box of small ... Read More
Amoebae — a group of amorphous, single-celled organisms that live in the human body — can kill human cells by biting off chunks of intestinal cells until they die, a new study finds. This is the first time scientists have seen this method of cell killing, and the new findings could one day help ... Read More
Q) Dr. Tim Sandle, the well known researcher, professor, author and science communicator. It is much interesting for me to take an interview of an eminent person who is well known for the communicating science. Starting from your early childhood life, how you used to take science as that time?

Worried about you or your kids picking up the flu virus or other common illnesses at school, in restrooms or at the mall? There’s good reason: Viruses and bacteria run rampant on the surfaces you touch every day. We blow the lid on the 8 germiest public places and give you expert tips to avoid g... Read More
A common ingredient in antibacterial soap can be found in some people's noses, and the presence of this ingredient could be promoting the colonization of Staph bacteria, according to a small new study in the journal mBio.
Researchers from the University of Michigan found triclosan in the nasa... Read More
Analytical Chemistry Researchers have created a spinning disk that can quickly tell--within 30 minutes--if food samples contain Salmonella. The most widely-used method to test for the pathogen involves growing out samples on petri dishes and can take days so this has potential to be much quicker... Read More
It’s a jungle in there. In the tightly woven ecosystem of the human gut, trillions of bacteria compete with one another on a daily basis while they sense and react to signals from the immune system, ingested food and other bacteria.
Problems arise when bad gut bugs overtake friendly ones, or... Read More
About eight percent of human DNA is viral – remnants of ancestral infections with retroviruses. These endogenous retroviral sequences do not produce infectious viruses, and most are considered to be junk DNA. But some of them provide important functions. The protein called syncytin, which is ess... Read More
Staphylococcus aureus is a commensal and an opportunistic pathogen that causes a large range of community and hospital-acquired infections. The bacteria produce an array of virulence factors, the expression of which is regulated by a set of regulators including proteins and RNAs. In recent years... Read More
Scientists at The University of Texas at Austin have discovered that a protein produced by the influenza A virus helps it outwit one of our body's natural defense mechanisms. That makes the protein a potentially good target for antiviral drugs directed against the influenza A virus.
Better an... Read More
Every year, Americans send millions of tons of food to the landfill. What if you could use all of those pizza crusts and rotten vegetables to heat your home? That's already happening in one unlikely laboratory: the Newtown Creek Wastewater Treatment Plant in Brooklyn.
The plant's longtime sup... Read More
Two people in England have developed tuberculosis after contact with a domestic cat, Public Health England has announced.
The two human cases are linked to nine cases of Mycobacterium bovis infection in cats in Berkshire and Hampshire last year.
Both people were responding to treatment, PH... Read More
Trimethoprim is more effective against streptococci than expected. Scarlet fever and infections of the skin and throat are often caused by a bacterium called Streptococcus pyogenes. In less-developed countries, inexpensive and well-tolerated antibiotics for therapy are often not available. Scien... Read More
We’ve seen mobile phone lens attachments and hacks that help you to take macro photos with your smartphone, but never before have we seen one that helps capture micro images.
It attaches to any smartphone or tablet via an adhesive backing and — using the slides provided in combination with a ... Read More
Ever wonder why fruits and vegetables sometimes hit the shelves contaminated by pathogenic bacteria such as listeria, E. coli, and salmonella? According to Tim Lu, an assistant professor of electrical engineering and biological engineering at MIT, it boils down to the inefficient bacteria-detect... Read More
