Aaron E. Carroll, professor of pediatrics at Indiana University School of Medicine, discusses the five-second rule about dropping food on the floor and still eating it. He reminds us that we touch lots of dirty surfaces everyday, from cell phone screens to money and even the kitchen sink sponge.... Read More
How widespread is Zika in South East Asia? At least 19 countries and areas in the region have reported locally transmitted cases since 2007, according to the WHO. The majority - 13 - reported their cases this year. Thailand has recorded some 350 cases and Singapore nearly 400, including pregnant... Read More
Using household wastewater to irrigate food crops in drought-stricken or arid regions isn't the perfect solution. The chemicals and disease-causing germs it might contain could contaminate crops. Viruses that have their origin in the human intestines are often released into the air as fine spray... Read More
Looking for population shifts on satellite images could be a way to deliver vaccines and prevent or control disease outbreaks, a new study finds.
The findings, published in Scientific Reports, are based on analysis of satellite images, vaccine records, and measles case reports.
The researc... Read More
Clinical Professor of Medicine at New York University and NYT writer, Lawrence K Altman, remembers Donald J. Henderson, MD, and his role in the eradication of small pox.
"The path to this monumental public health victory was tortuous, full of mini disasters, bureaucratic quagmires, rivalries,... Read More
Caenorhabditis elegans (often abbreviated C. elegans) is a roundworm (nematode) used as a model system not only to study human diseases but also for understanding fundamental biological processes.
"Now we know that Caenorhabditis elegans do have the ability to produce chondroitin sulfate. Th... Read More
A new 3-D printed, easily assembled smartphone microscope developed at Stanford University turns microbiology into game time. The device allows kids to play games or make more serious observations with miniature light-seeking microbes called Euglena.
When it’s assembled, it has a platform for... Read More
A team of researchers with members from Italy, Australia, the U.S. and Japan has found that viruses are the main culprit in killing archaea in the deep sea. In their paper published in the journal Science Advances, the researchers describe the techniques they used to study archaea in soil sample... Read More
The LudusScope is an interactive smartphone microscope that can be made entirely out of 3D printed or commonly available materials and is easily assembled by middle school or high school students. Developed by Stanford bioengineer Ingmar Riedel-Kruse, it allows students to interact directly with... Read More
Eating slow-release carbs and cutting down on protein may prevent rotten-egg farts according to a study of the gases emitted by human faeces samples.
Farts are mostly composed of odourless gases. There is oxygen and nitrogen from swallowed air, while hydrogen, methane and carbon dioxide are p... Read More
The results of a clinical trial suggest it is possible to modify the body’s response to an infection with a related virus.
The researchers report in Nature Microbiology that antibodies, under specific conditions, can intensify infection with a virus related to the causal organism. This phenom... Read More
If the previous occupant of a hospital bed received antibiotics, the next patient who uses that bed may be at higher risk for a severe form of infectious diarrhea, according to a new study.
Clostridium difficile (C. diff) diarrhea causes 27,000 deaths each year in the U.S. Hospital patients t... Read More

Researchers have discovered the strongest evidence yet linking the Zika virus to the paralytic illness Guillain-Barre syndrome. During the height of the viral epidemic the incidence of Guillain-Barre was 100 times the number of cases usually seen.
Guillain-Barre is a normally rare condition t... Read More
Naturally occurring bacteria could consume pent-up hydrogen gas in nuclear waste repositories to prevent radioactive leaks, say researchers at EPFL.
Scientists may have found an unexpected ally in the long-term disposal of nuclear waste: bacteria. In a recent study, a research team led by EPF... Read More
The night after receiving the news about winning the 2016 Nobel Prize in Physiology or Medicine, microbiologist Yoshinori Ohsumi expressed his eagerness to build a new research center for microbiology and create a system for supporting young scientists.
"Microorganisms support the living worl... Read More
In an attempt to preserve and defend the good name of the salmon fished in his state, Senator Warren Magnuson (D-WA), introduced in 1969 a bill in the US Senate proposing to change the name of Salmonella to the more inoccuous sounding Sanella. In some circles it may seem comforting to th... Read More
The Nobel Prize for Medicine this year went to Dr. Yoshinori Ohsumi of the Tokyo Institute for Technology for his work on autophagy, the process of digesting unneeded or damaged cellular components. This process plays a role in many central cellular activities, with applications ranging from gen... Read More
