In Pakistan prevalence and drug resistance of TB is on the rise. Late diagnosis and lack of resources are making the situation worse. In such a scenario molecular techniques such as PCR and hybridization would help in early diagnosis of TB and MDR TB leading to commencement of treatment at the r... Read More
Methicillin-resistant S. aureus (MRSA) constitutes approximately 50% of clinical S. aureus isolates and is most commonly the result of production of a mutated pencillin-binding protein, PBP2a, which is able to carry out essential cell wall synthesis functions while maintaining a low-affinity for...

A University of Otago researcher is part of an international team that has discovered that horizontal gene transfer (HGT) played a surprisingly large role in the evolution of primitive microbes known as archaea.
HGT, which involves acquiring genetic material from another unrelated organism in... Read More
Speedy analysis reveals mutations, insights into outbreak, along with clues to origin, spread.
Responding rapidly to the deadly outbreak of Ebola virus disease (EVD) in West Africa, a team of researchers from the Broad Institute and Harvard University, working with the Sierra Leone Ministry o... Read More
Ever since a highway construction crew in Chile uncovered a fossil graveyard of some 40 prehistoric whales in 2010, with skeletons dating back more than five million years, scientists have wondered why so many giant animals died in one place. This week, a team of them proposed an answer: The hug... Read More
If a sexually active woman wants to protect herself from unwanted pregnancy and HIV using a single method, she has always been limited to condoms. A new paper, released today in PLOS ONE details a first-of-its-kind device that provides an alternative.

A pesar de los beneficios que suponen las vacunas, muchas personas desconocen cómo funcionan e incluso desconfían de su acción. Las vacunas siempre son más seguras que la propia enfermedad de la que protegen. Algunas enfermedades infecciosas no tienen un tratamiento efectivo y las vacunas son la... Read More
Infections in the central nervous system are rare thanks to our brain's unique defence system that prevents viruses from invading, finds a study. The research explains a long-standing mystery.

McMaster scientists have found that an anticonvulsant drug may help in developing a new class of antibiotics.
Although dozens of antibiotics target what bacteria do, their study has looked at how a certain part of bacteria are created, and they found there is a way of stopping it.
The disc... Read More
Growth of Acetobacter pasteurianus on glucose, yeast extract, calcium carbonate, ethanol medium.
Formation of acetic acid from ethanol oxidation is shown by a clear halo around bacterial growth due to dissolution of calcium carbonate.
Organism: Acetobacter pasteurianus. Incubation conditions:... Read More
India is scrambling to protect its beleaguered tiger population after several big cats tested positive for a virus common among dogs but deadly to other carnivores, experts said.
In the last year, canine distemper virus has killed at least four tigers and several other animals across northern... Read More
Researchers have discovered that a type of white blood cell carries a deadly fungus into the brains of HIV positive patients, causing meningitis which kills more than 600,000 people a year. The discovery could lead to more effective ways of tackling the deadly fungus as it infects the human body... Read More
One of the food industry’s major recurring challenges, detecting highly carcinogenic toxins that occur naturally in our most common crops, could soon be solved by groundbreaking research that exploits aflatoxins’ fluorescent properties.
Aflatoxins are present in a wide... Read More
Modern Earth is nothing like it was in its early days. Our planet was formed some 4.56 billion years ago when a giant stellar cloud collapsed on itself due its massive size and gravitational force. The explosion also generated the sun and many other planetary bodies, including those that would e... Read More
The same viruses that make us sick can take up residence in and on the human body without provoking a sneeze, cough or other troublesome symptom, according to new research. On average, healthy individuals carry about five types of viruses on their bodies, the researchers report. The study is the... Read More
The traditional light microscope is bulky and expensive. Dr Tri Phan and Dr Steve Lee from the Garvan Institute of Medical Research and Australian National University used gravity to manufacture high-performance polymer lenses. These can be seamlessly integrated with 3D printing and mini-LEDs to... Read More
How handy would it be if, instead of taking your broken circuit board to the Genius Bar (again), you could just prompt it to heal itself? That’s the futuristic possibility researchers have recently inched ever so slightly toward, with the development of hybrid “living materials” made from bacter... Read More
Scientists working to understand the devastating bat disease known as white-nose syndrome (WNS) now have a new, non-lethal tool to identify bats with WNS lesions —ultraviolet, or UV, light.
If long-wave UV light is directed at the wings of bats with white-nose syndrome, it produces a distinct... Read More
Natural disasters such as earthquakes can have far-reaching effects beyond the damage caused on the day they occur. The 2010 earthquake in Haiti damaged the already limited sanitation systems leading to areas without adequate toilet and washing facilities; perfect for the spread of infection dis... Read More
