Inside the Australian Lab That Helps the WHO Try to Determine the Best Way to Stop the Virus.
The annual fight to keep the flu under control starts here.
Doctors are studying nose and throat swabs from flu sufferers sent from laboratories around the world, from Texas to the Solomon Islands... Read More
In a recent study, scientists at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), demonstrate for the first time that ocean acidification could have negative impacts on diatoms in the Southern Ocean. In laboratory tests they were able to observe that under chan... Read More
Intracellular pathogens face many daunting problems, among them how to obtain enough energy and nutrients for active growth while, preferably, keeping the host cell alive for as long as possible. This issue is especially acute for pathogens that grow at a fast rate and reach large numbers. When ... Read More
You must have heard it said that no one is indispensable to an institution. Maybe so, but such truths come in degrees. Every so often someone comes along who makes a genuine difference in how an organization functions. I turn here to Michael Goldberg, who thirty years ago began a most distinguis... Read More
If you've ever enjoyed the scent of a pine forest or sniffed a freshly cut basil leaf, then you're familiar with terpenes. The compounds are responsible for the essential oils of plants and the resins of trees. Since the discovery of terpenes more than 150 years ago, scientists have isolated som... 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
For many people microbes are associated with infections, diseases and in general mainly negative things but some microbes actually do more good than bad for us. We often take for granted that without microbes we would not have many things that we eat and use everyday and, as a matter of fact, hu... Read More
Saint Louis University research findings published in the December issue of Antimicrobial Agents and Chemotherapy report a family of molecules known as nucleotidyltransferase superfamily (NTS) enzyme inhibitors are promising candidates for new herpes virus treatments.
The findings could lead ... Read More
Since life originated on Earth between 3.8 and 3.9 Ga ago, microorganisms have significantly shaped and influenced the chemistry of Earth’s surface and subsurface environments. Reconstructing the evolution of early microbial life depends mainly on finding organic and mineral remnants of microbia... Read More
Data confirms that there is transmission of fecal coliforms in communal bathrooms at Quinnipiac University and that toothbrushes can serve as a vector for transmission of potentially pathogenic organisms.

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
UNSW Australia researchers have shown that changing just a single letter of the DNA of human red blood cells in the laboratory increases their production of oxygen-carrying haemoglobin - a world-first advance that could lead to a cure for sickle cell anaemia and other blood disorders. 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
A bacterium has been used to wish people a Merry Xmas. Grown by Dr Munehiro Asally, an Assistant Professor at the University of Warwick, the letters used to spell MERRY XMAS are made of Bacillus subtilis, a non-pathogenic bacterium which is found in soil and also human gut.
When you’re the size of a human, you worry about lions and tigers and bears. But if you’re a bacterium, a tiny nematode worm, just a millimetre long, can be a vicious predator. Nematodes are among the most common animals on the planet, and many of them hunt bacteria in soil and water. The microb... 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...

An experimental compound empowers an enzyme to help process acetaldehyde, a toxic metabolite of alcohol, according to new research supported by the National Institute on Alcohol Abuse and Alcoholism (NIAAA). The findings, now online in the Proceedings of the National Academy of Sciences (PNAS), ... Read More

Most vaccines work by inducing an immune response characterized by neutralizing antibodies against the respective pathogen. An effective HIV vaccine has remained elusive so far, but researchers have continued to make progress, often employing innovative methods. A new study reports that a combin... Read More
