One of the most comprehensive studies to date of the microbes that are found in extremely low-birthweight infants found that hard-to-treat Candida fungus is often present, as well as some harmful bacteria and parasites. Researchers at the Duke University Medical Center and Nicholas School of the Environment looked at the microbes in 11 premature infants and found much less diversity than in full-term infants. "The babies' guts were taken over by microbes we know are dangerous if they...

How Old Yeast Cells Send Off Their Daughter Cells Without The Baggage Of Old Age
2011-11-24 04:40:35

[ Watch the Video ] The accumulation of damaged protein is a hallmark of aging that not even the humble baker's yeast can escape. Yet, aged yeast cells spawn off youthful daughter cells without any of the telltale protein clumps. Now, researchers at the Stowers Institute for Medical Research may have found an explanation for the observed asymmetrical distribution of damaged proteins between mothers and their youthful daughters. Reporting in the Nov. 23, 2011, issue of Cell the research...

UC Riverside entomologists explain why flies are attracted to beer and products of yeast fermentation Ever wondered why flies are attracted to beer? Entomologists at the University of California, Riverside have, and offer an explanation. They report that flies sense glycerol, a sweet-tasting compound that yeasts make during fermentation. "Insects use their taste system to glean important information about the quality and nutritive value of food sources," said Anupama Dahanukar, an...

Commanding Yeast Genes With Computers

Scientists in Switzerland have managed to form a “feedback loop” between a computer and a common yeast, precisely controlling the switching on and off of specific genes. This could herald the ability to control biological processes, such as creating biofuel from microbes, Jason Palmer of BBC News reports. “The neat thing about this is that there are many people who have tried to do things like this by, for example, coding in the cell itself a synthetic circuit, putting...

[ Watch the Video ] Any way you slice it, bread that contains critical nutrients could help combat severe malnutrition in impoverished regions. That is the goal of a group of Johns Hopkins University undergraduate students who are using synthetic biology to enhance common yeast so that it yields beta carotene, the orange substance that gives carrots their color. When it´s eaten, beta-carotene turns into vitamin A. The students´ project is the university´s entry in iGEM,...

Scientists have synthesized from scratch a so-called chromosome "arm"--one of the largest DNA molecules ever synthesized, and developed a new method for shuffling an organism's genetic deck Scientists have replaced all of the DNA in the arm of a yeast chromosome with computer-designed, synthetically produced DNA that is structurally distinct from its original DNA to produce a healthy yeast cell. (Yeast chromosomes are often depicted as bow tie-shaped--with each chromosome bearing two...

Johns Hopkins researchers create man-made system with built-in diversity generator In the quest to understand genomes–how they're built, how they're organized and what makes them work–a team of Johns Hopkins researchers has engineered from scratch a computer-designed yeast chromosome and incorporated into their creation a new system that lets scientists intentionally rearrange the yeast's genetic material. A report of their work appears September 14 as an Advance Online...

University of Illinois scientists have engineered a new strain of yeast that converts seaweed into biofuel in half the time it took just months ago. That's a process that's important outside the Corn Belt, said Yong-Su Jin, a University of Illinois assistant professor of microbial genomics and a faculty member in its Institute for Genomic Biology. "The key is the strain's ability to ferment cellobiose and galactose simultaneously, which makes the process much more efficient," Jin said....

New research suggests oxygen may have been made on Earth hundreds of millions of years before its debut in the atmosphere. MIT researchers found evidence that tiny aerobic organisms may have evolved to survive on extremely low levels of the gas in these undersea oases. Former MIT graduate student Jacob Waldbauer found while working with colleagues that yeast is able to produce key oxygen-dependent compounds, even with only minuscule puffs of the gas. The research suggests that early...
