Human Sweat's Filthy Attributes Stop Bacteria-Fighting Brass

Human sweat is actually much dirtier and bacteria-filled than we initially thought. Scientists have found that sweaty hands can reduce the effect that brass objects have of fighting bacteria. Brass objects can be found in hospitals and schools and sweat can fight off its abilities just an hour a... Read More

Multiple protocol breaches behind anthrax exposure at U.S. federal labs

The safety breach at a government lab that may have exposed 84 workers to live anthrax centered on a pivotal lapse in procedure: researchers working with the bacteria waited 24 hours to be sure they had killed the pathogens, half the time required by a new scientific protocol.

The lab designe... Read More

Virus-induced fever might change bacteria from commensal to pathogen

Neisseria meningitidis may cause septicemia (bacteria in the blood) and meningitis (infection of the membrane surrounding the brain), but the bacterium colonizes the nasopharynx in 10-20% of the human population without causing disease. Although understanding how the bacterium changes from a com... Read More

Rising star uses paper to tackle food-borne diseases

A University of Alberta researcher’s star is rising thanks to her idea to detect deadly pathogens such as E. coli using a paper device only slightly larger than a postage stamp.

Frédérique Deiss, a post-doctoral fellow in the Faculty of Science, is working on ways to help detect food- and wat... Read More

The truth behind the '5-Second Rule': When in doubt, throw it out

The burger patty that slides off the plate, the ice cream treat that plops on the picnic table, the hot dog that rolls off the grill – conventional wisdom has it that you have five seconds to pick it up before it is contaminated.

Fact or folklore?

“A dropped item is immediately contaminate... Read More

Greetings Vincent and Dick,


Hooray for finally mentioning G. pulchrum in episode 62, my most favorite parasite and one worthy of further discussion. As a diagnostic veterinary pathologist, I encounter this spirurid in approximately... Read More

New Research on Antibiotic-Resistant Bacteria, Pressure Ulcers, Severe Alcoholic Hepatitis, and More

Two million people suffer antibiotic-resistant infections yearly, and 23,000 die each year as a result. Most of these infections occur in the community, but deaths usually occur in healthcare settings. Cost estimates vary but may be as high as $20 billion in excess direct healthcare costs.

C... Read More

New life form discovered at MSU, named after Bully

Some Mississippi State University students have discovered – and named – a new life form, a previously unknown organism discovered on campus in a mud puddle last September.

The newly classified organism – Ptolemeba bulliensis, a unicellular microscopic protest – was scooped from a courtyard b... Read More

Bacteria-Eating Viruses 'Magic Bullets in the War On Superbugs'

A specialist team of scientists from the University of Leicester has isolated viruses that eat bacteria -- called phages -- to specifically target the highly infectious hospital superbug Clostridium difficile (C. diff).

Now an exciting new collaboration between the University of Leicester, th... Read More

Cubist & Cambridge Science Festival Launch "Germ Challenge" Science Contest

LEXINGTON, Mass. & CAMBRIDGE, Mass.--(BUSINESS WIRE)--February 13, 2014--
Cambridge Science Festival and Cubist Pharmaceuticals, Inc. (NASDAQ: CBST) today launched the 2014 "Germ Challenge," a contest designed to engage young people in science by inviting them to create educational and creativ... Read More

Soil microbiomes can set plant flowering time

Scientists grew Boechera stricta plants in soil inoculated with microbes from natural B. stricta habitats to study the flowering time phenotype.

The technique researchers employed to isolate soil microbes to study their effect on a single plant phenotype can potentially be applied to other st... Read More

How U.S. Hospitals Are Planning To Stop The Deadly MERS Virus

In the past month, Middle East Respiratory syndrome has morphed from a little-known disease in the Arabian Peninsula to a major global health concern, with more than 300 cases in Saudi Arabia in April, 54 of them fatal.

Two cases have been reported in the U.S. as well — one in Indiana and one... Read More

Researchers map gene differences in yellow fever, malaria mosquitoes, to help prevent disease

Virginia Tech entomologists have developed a chromosome map for about half of the genome of the mosquito Aedes agypti, the major carrier of dengue fever and yellow fever.

With the map, researchers can compare the chromosome organization and evolution between this mosquito and the major carri... Read More

Researchers create better methods to detect E. coli

Kansas State University diagnosticians are helping the cattle industry save millions of dollars each year by developing earlier and accurate detection of E. coli.

Lance Noll, master's student in veterinary biomedical science, Greensburg; T.G. Nagaraja, university distinguished professor of di... Read More

Frozen bacteria repair their DNA at -15ºC

Bacteria encased in ice can be resuscitated after thousands, perhaps even millions of years. How these hardy bugs manage to survive deep freeze is something of a mystery. If nothing else, the low levels of radiation hitting Earth’s surface should cause any ice-bound bacterium’s DNA to break apa... Read More

New chip lets scientists listen in on bacteria

Researchers at Columbia University are turning that optics-based imaging approach on its head, instead developing a chip based on integrated circuit technology that lets them not only electrochemically image bacteria, but listen in on them as well.

Study: Salad Ingredient Kills Drug-Resistant TB

One of the world's oldest known disinfectants – and favorite salad dressings – may prove even stronger than previously thought.

An international research team has found that vinegar – or, more specifically, the active ingredient in vinegar – can kill mycobacteria, including a highly drug-resi... Read More

Hebrew U. researchers reach breakthrough on understanding how persistent bacteria are able to avoid antibiotics

In addition to the known phenomenon by which some bacteria achieve resistance to antibiotics through mutation, there are other types of bacteria, known as “persistent bacteria”, which are not resistant to the antibiotics but simply continue to exist in a dormant or inactive state while exposed t...
