Should we only consider bacteria as harmful to our bodies?
Bonnie Bassler is a molecular biologist who has made a stunning discovery: bacteria 'talk' to each other using chemical signals that enable them to act as a unit, mount attacks and coordinate defence. This phenomenon of bacterial com... Read More
Once again, you've dropped your snack. You bend down, snatch it up, and gently blow off any dust—and, you hope, deadly germs. You're about to put it in your mouth because, after all, you've got the "five-second rule" on your side: Food that's been dropped is safe to consume if it's been on the f... Read More
I listened to the latest TWIP this morning. Dickson mentioned the herbicide atrazine but thought it was a fungicide. It is actually a herbicide in the photosynthesis inhibitor class. Another bit of trivia about ag chemicals is that old chemicals like ... Read More
Another child has been infected with a rare, brain-eating parasite, less than a month after Kali Hardig ended up in an Arkansas hospital, fighting for her life.
The new patient is 12-year-old Zachary Reyna, his family told CNN affiliate WBBH. A spokesperson for the Hendry-Glades Health Depart... Read More

Fossilized microbes have provided scientists many clues about origins of life. By comparison, little attention is given to viruses in the fossil record. Although technically non-living, there is no question these tiny packets of protein-sheathed DNA have shaped the evolution of most life on eart... Read More
A team of European scientists say they have discovered a compound that can prevent the spreading of coronaviruses, responsible for the SARS and MERS outbreaks that have killed about 1,000 people worldwide.

Aunque el género Mycobacterium es asociado a infecciones tales como la lepra y la tuberculosis, hay un gran número de especies que son por lo general no patogénicos o patógenos oportunistas. En el episodio de hoy tenemos al Dr. Ricardo Santos del Instituto Superior Técnico de Lisboa, Portugal... Read More
Only 148 cases of Guinea worm disease were found in the world in 2013, a 73 percent drop from the 542 cases found one year earlier, the Carter Center announced Thursday.
Along with polio, Guinea worm is one of two diseases hovering on the brink of extinction, with fewer than 1,000 cases annua... Read More
CHICAGO, Jan. 6 (UPI) -- The largest outbreak ever of a rare but potentially deadly bacteria has been tied to equipment in a Chicago-area hospital, health officials said.
The Centers for Disease Control and Prevention said 44 cases of infection by the bacteria carbapenem-resistant enterobacteri... Read More
Well-known faces including Stephen Fry and Carol Vorderman are helping make art out of science by taking part in an experiment to grow portraits using their own bacteria.
The celebrities teamed up with American microbiologist and photographer Zachary Copfer to make the images by contributing ... Read More
Scientists were able to reliably predict the timing of the 2012-2013 influenza season up to nine weeks in advance of its peak. The first large-scale demonstration of the flu forecasting system by scientists at Columbia University’s Mailman School of Public Health was carried out in 108 cities ac... Read More
The H1N1 virus responsible for the 2009 global pandemic is back. State health officials from across the country say the resurgence is resulting in a dramatic rise in flu deaths in young and middle-aged adults and in children this season.
While the reported death tolls so far are only a fracti... Read More

The science behind the transformation from plants to milk to cheese is amazing. In fact, cheese has much in common with wine and beer: They result from fermentation by microorganisms; they are “value-added” products where processing greatly increases the value; and they reflect local climate and...
