Five people in Saudi Arabia have died from a Sars-like virus and two more are seriously ill, officials say. The seven cases were all from al-Ahsa governorate in the east of the country, the Saudi news agency SPA said citing health officials. The novel coronavirus (NCoV) causes pneumonia and some...

As the lakefront officially opens to swimmers Friday, the Lake Michigan shoreline joins the cutting edge in the war on bacteria after decades of using day-old water samples to decide whether to close beaches.
In Chicago, the Park District will use a new high-tech system that uses computer sof... Read More
Bacteria are all over us, inside and out. Jiri Hulcr recently found 1,458 species of bacteria "new to science" in a small sample of human belly buttons. What we know about our little passengers and how they affect our bodies is dwarfed by what we do not. That can be disconcerting to think about,... Read More
Our gut is home to trillions of bacteria, numbering more than the cells in the rest of our body, and these bacteria help us to digest our food, absorb nutrients and strengthen our immune system. This complex bacterial ecosystem, called the gut microbiota, also helps to prevent bad bacteria from ... Read More
Diseases transmitted by mosquitoes have a devastating impact on global health and the situation is complicated due to difficulties with both existing control measures and the impact of climate change. Genetically modified mosquitoes that are refractory to disease transmission are seen as having ... Read More
US outbreak foxes a leading web-based method for tracking seasonal flu. When influenza hit early and hard in the United States this year, it quietly claimed an unacknowledged victim: one of the cutting-edge techniques being used to monitor the outbreak. A comparison with traditional surveillance... Read More
Scientists from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, have identified the structure of a critical RSV component called the fusion glycoprotein.
Respiratory syncytial virus, or RSV, is a respiratory virus that infects th... Read More
In 2011, Lake Erie experienced the largest algae bloom in its recorded history. At its peak in October, the mat of green scum on the lake’s surface was nearly four inches thick and covered an area of almost 2,000 square miles. That’s three times larger than any other bloom in the lake, ever. Plu... Read More
Good microbiologists question assumptions. How about the assumption that semesters are the best calendars for learning? What would happen if rather than taking four courses concurrently during a semester, students instead took those four courses successively, one at a time? This describes the Co... Read More
Los anfibios que actúan como indicadores del estatus del ecosistema; éste es el tema que será discutido en el episodio de hoy con nuestra invitada, la Dra. Read More
Microbes turn nutrient in beef into an artery-clogging menace. Lean steak is low in fat and cholesterol and high in protein — qualities normally considered healthy. But eating a lot of it can still cause heart disease. Researchers have now laid the blame on bacteria in the human gut that convert... Read More
New scientific research published today in the journal PLoS Biology shows that bacteria can evolve resistance more quickly when stronger antibiotics are used.
Researchers from the University of Exeter and Kiel University in Germany treated E. coli with different combinations of antibiotics in... Read More
Researchers at the Johns Hopkins Malaria Research Institute have developed a new method for studying the complex molecular workings of Anopheles albimanus, an important but less studied spreader of human malaria. An. albimanus carries Plasmodium vivax, the primary cause of malaria in humans in S... Read More
Tumor necrosis factor – normally an infection-fighting substance produced by the body – can actually heighten susceptibility to tuberculosis if its levels are too high. University of Washington TB researchers unravel this conundrum in a report this week in Cell. Their study shows how excess prod... Read More
This is a movie by David Bella, Ph.D., at the University of Glasgow Centre for Virus Research showing the results of an analysis of Adenovirus binding to blood coagulation factor X, performed in collaboration with Professor Andrew H Baker in the University of Glasgow.
The animation was creat... Read More
Two dangerous things together might make a medicine for one of the hardest cancers to treat. In a mouse model of pancreatic cancer, researchers have shown that bacteria can deliver deadly radiation to tumours — exploiting the immune suppression that normally makes the disease so intractable.

Most people are fascinated by the colorful and exotic coral reefs, which form habitats with probably the largest biodiversity. But human civilisation is the top danger to these fragile ecosystems through climate change, oxygen depletion and ocean acidification. Industrialisation, deforestation a... Read More
Some facts about the toxin that was found in a letter addressed to US senator Roger Wicker. Government officials in Washington have shut down mail delivery to the US Senate after detecting ricin in a letter addressed to Mississippi senator Roger Wicker, a Republican, on 16 April. Here are some f... Read More
Temperatures on the surface of the tropical South Atlantic Ocean in July can predict the severity of malaria outbreaks in northwestern India that begin to peak four months later, Howard Hughes Medical Institute researchers have discovered.
The correlation they have found between ocean tempera... Read More
A simple new method better assesses the risks posed by emerging zoonotic viruses (those transmissible from animals to humans), according to a study published in PLOS Medicine this week. Dr. Simon Cauchemez and colleagues from Imperial College London in the UK and the Centers for Disease Control ... Read More
