Scientists at the University of Sussex, trying to uncover how the common Epstein-Barr virus causes blood cancer in adults and children, have discovered how the virus takes control of two genes involved in cancer development so it can switch them on or off.
For the first time in 60 years, a tropical bed bug has been confirmed in Florida, and University of Florida Institute of Food and Agricultural Sciences researchers urge the public to send them samples of suspected bed bugs for identification.
Scientists have developed a type of HIV test on a USB stick. The device, created by scientists at Imperial College London and DNA Electronics, uses a drop of blood to detect HIV, and then creates an electrical signal that can be read by a computer, laptop or handheld device. The disposable test could be used for HIV patients to monitor their own treatment. Furthermore, the technology could enable patients with HIV to be managed more effectively in remote locations.
For most invading bacteria, the bladder is not a friendly place. But for those that have figured out how to scavenge iron from their hosts, it’s a fine place to grow and reproduce. And for millions of women a year, that means painful, burning, potentially dangerous urinary tract infections. Now, in an ironic twist, scientists have turned that iron-scavenging power against the most common UTI-causing bacteria.
Researchers at Vanderbilt University Medical Center and Washington University School of Medicine in St. Louis, Missouri, have isolated a human monoclonal antibody that in a mouse model “markedly reduced” infection by the Zika virus.
It is estimated that in Germany alone around 150,000 people fall ill with sepsis every year; despite medical advances, between 30 percent and 50 percent of the patients still die of the consequences. One of the reasons for the high mortality rate: the diagnosis often comes too late for the lifesaving therapy with antibiotics that only combat the specific causative pathogen. In general the sepsis pathogens are detected by means of so-called blood cultures in which the pathogenic organism from blood samples of the patients are cultivated in the laboratory. Here, two to five days pass before the pathogens have multiplied and a result is available. Due to rapid progress in nucleic acid analysis, the currently available high-throughput technologies (Next-Generation Sequencing) make it possible to sequence the complete genome of organisms within just a few hours and to check them against known gene sequences.
Scientists from the universities of Granada (UGR) and Valencia (UV) have developed a new molecular method for determining the presence of the parasite Toxoplasma gondii, which causes toxoplasmosis, in samples of ham.
Research co-led by bioscientists at the University of Kent provides a molecular explanation for how the bacterium behind the super bug MRSA produces a red pigment that is crucial for its rapid growth.
