Considered as an obsolete theory for many years, the transmission of acquired traits has returned to the forefront of debate thanks to the development of epigenetic research. In this context, a team of researchers has described how in Paramecia, mating types are transmitted from generation to ge... Read More
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
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
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
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
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
Nearly two years after the Deepwater Horizon disaster gushed millions of barrels of oil into the Gulf of Mexico, tar balls from the spill still turn up on Alabama's shores after storms. Now, one researcher is recommending that people steer clear of these tar balls after studies find them chock-f... Read More
Saudi scientists have found gene fragments of the deadly Middle East Respiratory Syndrome (MERS) virus in air from a barn housing an infected camel and say this suggests the disease may be transmitted through the air.
MERS, a serious respiratory illness caused by a virus known as a coronaviru... Read More
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
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
Intracellular pathogens face many daunting problems, among them how to obtain enough energy and nutrients for active growth while, preferably, keeping the host cell alive for as long as possible. This issue is especially acute for pathogens that grow at a fast rate and reach large numbers. When ... Read More
Lessons learned from Florence Nightingale could prevent the spread of harmful bugs by allowing "friendly" bacteria into hospitals, an expert has claimed.
Sterile conditions in wards and operating theatres may be doing more harm than good by wiping out organisms that keep dangerous microbes at b... Read More
BDP 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
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
Is it possible that our personal hygiene routines make us too clean? Are we soaping and cleansing away friendly microbes that help preserve skin health? A study presented at the 5th American Society for Microbiology Conference on Beneficial Microbes in Washington, DC, provides food for thought o... Read More
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.

German an French Scientists found out: Soil bacteria contribute to the taste and smell of white truffles.
Truffles, along with caviar, are among the most expensive foods in the world. Because they grow underground, people use trained dogs or pigs to find them. But the distinctive smell of tru... Read More
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
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
