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...

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
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
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
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
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.
President Ellen Johnson Sirleaf of Liberia on Friday urged the United States to maintain its assistance to her country as it continues to fight to recover from the Ebola outbreak, which began about one year ago.
In a meeting at the White House with President Obama, Ms. Johnson Sirleaf asked f... Read More
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

Caring for People Infected with Ebola: Stories from the Frontlines
Narrative Inquiry in Bioethics will publish a collection of personal stories from individuals who have been at the frontlines of healthcare for Ebola patients—whether as healthcare workers, family caregivers,... 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
For four years, researchers at Universite catholique de Louvain have been trying to find out how bacteria can withstand antibiotics, so as to be able to attack them more effectively. These researchers now understand how one defense mechanism works and the results of their research have been publ... Read More
Its name means "bending over in pain." It has no treatment or vaccine. Its symptoms resemble Dengue fever. And it has infected more than 1 million people -- 155 of them fatally -- since spreading to the Americas one year ago.
The mosquito-borne Chikungunya virus has long been diagnosed in tra... 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
Methicillin-resistant Staphylococcus aureus is a common cause of hospital-acquired infections, with the largest burden of infections occurring in under-resourced hospitals. While genome sequencing has previously been applied in well-resourced clinical settings to track the spread of MRSA, transm... 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
Cells have finger-like projections that they use to feel their surroundings. They can detect the chemical environment and they can ‘feel’ their physical surroundings using ultrasensitive sensors. New research from the Niels Bohr Institute shows how the finger-like structures, called filopodia ca... Read More
The ancestors of a large family of parasites—including those that cause malaria—were equipped to become parasites much earlier in their lineage than previously assumed, according to University of British Columbia (UBC) research.
The work, published in PNAS, traces the emergence of parasitism ... Read More
