Bacterial Hopanoids – The Lipids That Last Forever

The world of lipids does not always gets its due. Their oleaginous charm is not always appreciated, as we said here before. For example, have you heard of hopanoids? They are made by some bacteria and are an unusual kind of polycyclic lipids that resemble steroids, but with an extra ring. Just l... Read More

Scientists Call for Investigation of Mysterious Cloud-like Collections in Cells

About 50 years ago, electron microscopy revealed the presence of tiny blob-like structures that form inside cells, move around and disappear. But scientists still don’t know what they do — even though these shifting cloud-like collections of proteins are believed to be crucial to the life of a c... Read More

Three Irish Teens Win Google Science Fair Using Bacteria to Grow Food

A trio of Irish high-schoolers nabbed the top prize in this year's Google Science Fair with a project that speeds up crop growth by tapping into the naturally cozy relationship between soil microbes and plants.

After 11 months of experiments, the three 16-year-olds—Ciara Judge, Émer Hickey, a... Read More

colony of candida spp.

Colonies of candida species:

Media: HiCrome Candida Differential Agar
principle: Perry and Miller (1) reported that Candida albicans produces an enzyme b -N-acetyl- galactosaminidase and according to
Rousselle et al (2) incorporation of chromogenic or fluorogenic hexosaminidase substrates... Read More

Scientists develop ‘electronic nose’ for rapid detection of C-diff infection

A fast-sensitive “electronic-nose” for sniffing the highly infectious bacteria C-diff, that causes diarrhoea, temperature and stomach cramps, has been developed by a team at the University of Leicester.

Using a mass spectrometer, the research team has demonstrated that it is possible to ident... Read More

Bacterial 'communication system' could be used to stop, kill cancer cells, study finds

Cancer, while always dangerous, truly becomes life-threatening when cancer cells begin to spread to different areas throughout the body. Now, researchers at the University of Missouri have discovered that a molecule used as a communication system by bacteria can be manipulated to prevent cancer ... Read More

Pneumonia bacterium leaves tiny lesions in the heart

The long-observed association between pneumonia and heart failure now has more physical evidence, thanks to research in the School of Medicine at The University of Texas Health Science Center at San Antonio.

The researchers found proof that Streptococcus pneumoniae, the leading cause of comm... Read More

A new way to diagnose malaria

Using magnetic fields, technique can detect parasite’s waste products in infected blood cells.

Over the past several decades, malaria diagnosis has changed very little. After taking a blood sample from a patient, a technician smears the blood across a glass slide, stains it with a special dye... Read More

'Deadly diarrhea' rates nearly doubled in 10 years: Study

Infections with the intestinal superbug C. difficile nearly doubled from 2001 to 2010 in US hospitals without noticeable improvement in patient mortality rates or hospital lengths of stay, according to a study of 2.2 million C. difficile infection cases.

Whole Genome Sequencing for Outbreak Detection of Salmonella enterica

Salmonella bacteria are a common cause of infectious disease in human and animals. Salmonella is classically divided into species S. bongori and S. enterica – which is in turn further divided into more than 2,500 different serotypes. However, only a limited number of serovars that are responsibl... Read More

Drug-Resistant Bacteria Hang Out in Hog Workers

Careful what you sniff. Especially if you work at an industrial hog farm. Because a small study finds that drug-resistant bacteria may hang out in the noses of some workers even after four days away from work following exposure. Almost half of the tested workers continued to harbor drug-resistan... Read More

"Immortal" Cells from Henrietta Lacks Lead to Updated Rules on Genomic Data Sharing

Scientists who work on genomics and are funded by the US National Institutes of Health (NIH) must post their data online so that others can build on the information, the agency has said in an update to its guidelines.

The change, which expands the remit of an earlier data-sharing policy, is ... Read More

BDP FL maleimide
http://www.lumiprobe.com/p/bodipy-fl-maleimide

BDP FL maleimide is a bright and photostable thiol-reactive dye for protein labeling, an ideal replacement for fluorescein for microscopy. BDP FL is a borondipyrromethene dye which has absorption and fluorescence spectra similar... Read More

Battling superbugs

Two new technologies could enable novel strategies for combating drug-resistant bacteria.

In recent years, new strains of bacteria have emerged that resist even the most powerful antibiotics. Each year, these superbugs, including drug-resistant forms of tuberculosis and staphylococcus, infect... Read More

Super-bacteria are growing in space ... and we're the ones breeding them

Manned space missions bring with them a plethora of challenges to keep astronauts alive and healthy, especially on long-duration space missions. Astronauts need to breathe, eat, drink, excrete their food and drink, and be kept free of infections to stay healthy enough to do their job. The key to... Read More

Yeast Coaxed To Make Morphine

Genetically manipulated yeast can produce morphine, which could help get around the problems with poppy crops, which include climate, disease and war. Karen Hopkin reports.

Yeast. They already participate in producing some of the most popular pain-killing substances around: beer and wine. Now... Read More

Scientist Gives Himself Fecal Transplant To Try A Hunter-Gatherer's Microbiome

Why a field researcher from America has exposed his colon to the gut microbiome of a tribesman from Tanzania.

It's not often we encounter a story that begins with a line like this:

“AS THE SUN set over Lake Eyasi in Tanzania, nearly thirty minutes had passed since I had inserted a turkey b... Read More

Who knew microbes could be so artistically inclined?

In the photo series "Impermanence," South Korean artist Seung-Hwan Oh creates colorful, otherworldly portraits with a little help from some "friends" — emulsion-consuming microbes, that is.

By immersing an exposed roll of medium-format positive film in water containing these bacteria and lea... Read More

Afraid of EV-D68? Another Deadly Virus Is Actually Killing Kids in U.S.

IIt’s all over the headlines: Enterovirus D-68 (EV-D68) is making kids sick in what appear to be unprecedented numbers. It might be causing paralysis — or maybe not. It may have infected some adults.

But EV-D68 is nothing compared to the viral killer that really concerns Dr. Paul Checchia of ... Read More
