Researchers save images not with a microchip, but with metabolites

Small molecules can encode data from an image and be read with over 98 percent accuracy

09-Jul-2019

An anchor, an ibex and an Egyptian cat: all images that a research team from Brown University, led by Jacob Rosenstein, encoded and decoded from mixtures of small molecules called metabolites. They demonstrate the potential of this small-molecule information storage system in a new paper ...

New vulnerability found in major human viruses

Structural feature may lead to antivirals for the common cold, polio, and other pathogens

13-Jun-2019

Discovery of a new feature of a large class of pathogenic viruses may allow development of new antiviral medications for the common cold, polio, and other illnesses, according to a new study publishing June 11 in the open-access journal PLOS Biology by Rana Abdelnabi and Johan Neyts of the ...

Pathogens find safe harbor deep in the gastric glands

06-May-2019

Scientists have long tried to understand how pathogenic bacteria like Helicobacter pylori, a risk factor for stomach ulcers and cancer, survive in the harsh environment of the stomach. In a new study in the open-access journal PLOS Biology, researchers led by Connie Fung and Manuel Amieva at ...

Manganese plays a key role in bacterial infection

25-Sep-2018

The ability to acquire manganese during infection is essential for the virulence of Enterococcus faecalis in animals, according to a study in PLOS Pathogens by José Lemos of the University of Florida College of Dentistry, and colleagues. Manganese is an essential micronutrient for bacterial ...

The role of dendritic cells in keeping HIV in check without drugs

16-Jun-2015

Elite controllers (EC) are a small group of HIV-infected individuals who are able to suppress the virus in the absence of antiretroviral therapy. EC demonstrate that the human immune system, in principle, is capable of rendering HIV harmless. A study published on June 11th in PLOS Pathogens shows ...

Can a viral co-infection impair immunity against Plasmodium and turn malaria lethal?

28-May-2015

It is known that infections with certain viruses can weaken the immune response to another pathogen. A study published in PLOS Pathogens reports provocative findings in mice that infection with the mouse equivalent of Epstein-Barr virus (EBV) can turn infections with certain parasites that cause ...

Chagas disease vaccine shows long-term protection in mice

12-May-2015

Chagas disease, caused by the Trypanosoma cruzi parasite and transmitted by insects in Latin America is among the most common tropical diseases, and so far without effective vaccine. A study published in PLOS Pathogens now shows that a candidate vaccine can induce long-lasting immunity against ...

New model finds HIV acute phase infectivity may be lower than previously estimated

20-Mar-2015

Previous calculations may have overestimated the importance of HIV transmission from recently infected individuals ("acute phase infectivity") in driving HIV epidemics, according to an article published by Steve Bellan of The University of Texas at Austin, and colleagues in this week's PLOS ...

Why do new strains of HIV spread slowly?

10-Feb-2015

Most HIV epidemics are still dominated by the first strain that entered a particular population. New research published in PLOS Computational Biology offers an explanation of why the global mixing of HIV variants is so slow.Researchers from Eötvös Loránd University; Bence Ferdinandy, Dr Viktor ...

Higher indoor humidity inactivates flu virus particles

Infectious capacity of influenza virus particles reduced at relative humidity of 40 percent or higher

04-Mar-2013

Higher humidity levels indoors can significantly reduce the infectivity of influenza virus particles released by coughing, according to research published in PLOS ONE by John Noti and colleagues from the National Institute for Occupational Safety and Health, Centers for Disease Control and ...
