Bacteria 'could be a cause of preterm births'

New research from the US has found a link between preterm births where the water sac around the baby breaks prematurely, and bacteria near where the walls of the sac are thinner.

The researchers, including Amy P. Murtha, associate professor of obstetrics and gynecology at Duke University Scho... Read More

HIV gets the zinc finger

Because all animal viruses initiate infection by binding to a receptor on the cell surface, this step has long been considered a prime target for antiviral therapy. Unfortunately, drugs that block virus attachment to cells have never shown much promise. Another approach, which is to ablate the r... Read More

Why Do Bacteria Thrive in Space?

For reasons that still aren't well understood, bacteria proliferate in microgravity. Creating a potential recipe for disaster for humans stationed in space for long periods, bacteria's love of low-g also raises an intriguing question: Why are they so comfortable there?

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

How to give a great lecture

There are many elements that go into making a great lecture, but the most important one is to lose the notes. If you are giving lectures in a course at any level, the worst practice you can engage in is to rely on notes. This behavior is problematic for several reasons. You will not properly kno...

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

Antibiotics work against viruses

Got your attention, eh? This page discusses why so many people believe that antibiotics kill viruses, and what you can do about that myth. Actually, it's not even a myth ... antibiotics DO work against viruses. The problem is that the word "antibiotics" is redefined by some to be a synonym of... Read More

New drugs for bad bugs

Washington University in St Louis chemist Timothy Wencewicz says we’ll stay ahead of antibiotic resistance only if we find drugs with new scaffolds, or core chemical structures. One promising candidate, an antibiotic made by a bacterium than infects plants, caught his attention because it contai... Read More

Gonorrhea Infections Start From Exposure To Seminal Fluid

Researchers have come a step closer to understanding how gonorrhea infections are transmitted. When Neisseria gonorrhoeae, the bacteria responsible for gonorrhea, are exposed to seminal plasma, the liquid part of semen containing secretions from the male genital tract, they can more easily move ...

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

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

Resurrecting ancient microbes to understand evolution

When you hear the word “resurrection”, what’s the first thing that comes to mind? Religious miracles? Zombie viruses? The end of the world?

Whatever your mental association, I’m willing to bet it’s not “an emerging scientific discipline." Well, it just so happens a growing community of microb... 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

Cartography of the Human Body

Artist Sonja Bäumel explores the skin microbiome in her project Cartography of the Human Body. Bacteria isolated from Bäumel’s skin were characterized and grown individually, then used to reconstruct an artificial microbiome with many layers of differently-colored species. Giant petri dishes gre... Read More

Battling Infection With Microbes

The human relationship with microbial life is complicated. At almost any supermarket, you can pick up both antibacterial soap and probiotic yogurt during the same shopping trip. Although there are types of bacteria that can make us sick, Caltech professor of biology and biological engineering Sa... 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...
