Three chaperones coordinate the breakup of amyloid fibrils in yeast
In a finding that has important ramifications for neurodegenerative disorders such as Alzheimer's disease, RIKEN researchers have discovered how three chaperone molecules in yeast cells work together to break up beta-sheet-rich fibrillar protein aggr.....»»
Yeast study offers possible answer to why some species are generalists and others specialists
In a landmark study based on one of the most comprehensive genomic datasets ever assembled, a team led by scientists at the University of Wisconsin–Madison and Vanderbilt University offer a possible answer to one of the oldest questions about evolu.....»»
Imaging technique shows new details of peptide structures
A new imaging technique developed by engineers at Washington University in St. Louis can give scientists a much closer look at fibril assemblies—stacks of peptides that include amyloid beta, most notably associated with Alzheimer's disease......»»
Researchers map protein network dynamics during cell division
An international team led by researchers at the University of Toronto has mapped the movement of proteins encoded by the yeast genome throughout its cell cycle. This is the first time that all the proteins of an organism have been tracked across the.....»»
Friend breakups: Why they can sometimes feel as bad as falling out of love
If you've ever gone through a friendship breakup you aren't alone—one study from the US found 86% of teenagers had experienced one......»»
Research challenges "universal mechanism" concept, aiming to understand specific protein interactions
Heat shock proteins (HSPs) are the chaperones of cellular stress response because they help guide the folding and unfolding of other proteins......»»
Yeast uses plastic waste oils to make high-value chemicals
Polyolefins are a type of plastic that is resistant to breaking down. This makes this plastic—a kind found in everything from grocery bags to car bumpers—hard to recycle. In a new study, scientists have discovered a potential solution, the yeast.....»»

Brewing kombucha in silicone bags makes for less alcohol, faster process
Using glucose instead of sucrose also results in less alcohol and less sour vinegar taste Enlarge / Brewing kombucha tea. Note the trademark gel-like layer of SCOBY (symbiotic culture of bacteria and yeast). (credit: Olga Pankova.....»»
Better kombucha brewing through chemistry
Kombucha is a fermented tea known for its health benefits and tangy kick. But brewers can find it challenging to keep kombucha's alcohol levels low because the bacteria and yeast used in the fermentation process vary from batch to batch......»»
Hierarchy expansion: When should a startup hire managers?
In a new study out of Vanderbilt Business, Professor Megan Lawrence explores a common challenge growing organizations face: how to continue to organize and coordinate the work of its growing body of employees......»»
Scientists use spent brewer"s yeast to filter out metal from waste streams
When we recycle electronic devices we can no longer use, we expect to make the most out of the precious natural resources that went into building them. But electronic waste is notoriously difficult to recycle because it's hard to separate the differe.....»»

Predatory fish use rapid color changes to coordinate attacks, scientists discover
Striped marlin are some of the fastest animals on the planet and one of the ocean's top predators. When hunting in groups, individual marlin will take turns attacking schools of prey fish one at a time. Now a new study reported in the journal Current.....»»
Creating a toolkit of yeast strains that over-produce key cellular building blocks
Microbes such as bacteria and yeast are increasingly being used to produce components of medicines, biofuels, and food. Indeed, baker's yeast, also known as brewer's yeast or Saccharomyces cerevisiae, is responsible for the fermentation process used.....»»
How fruit flies control the brain"s "steering wheel"
When we walk down the street, we have an internal sense of which way we are heading from looking at street signals and physical landmarks and also a sense of where we'd like to go. But how does the brain coordinate between these directions, doing the.....»»
Microbial division of labor produces higher biofuel yields
Scientists have found a way to boost ethanol production via yeast fermentation, a standard method for converting plant sugars into biofuels. Their approach, detailed in the journal Nature Communications, relies on careful timing and a tight division.....»»
An unconventional yeast increases the quality of carbonic maceration wine, rosé wine and orange wine
Carbonic maceration wines are increasingly in demand on the market. They are young red wines in which floral and fresh fruit aromas predominate and they must be consumed within the first year. The best-known example is Beaujolais nouveau in France, b.....»»
Researchers create light-powered yeast, providing insights into evolution, biofuels and cellular aging
You may be familiar with yeast as the organism content to turn carbs into products like bread and beer when left to ferment in the dark. In these cases, exposure to light can hinder or even spoil the process......»»
How to cope with heartbreak during the holidays
How do you cope with heartbreak over the holidays? How do you deal with a breakup over Thanksgiving or Christmas? Here's some advice and tips from therapists. It was Christmas Day night and I couldn't sleep. Not through excitement for continued.....»»
Researchers discover how cysteine activates a key regulator of cell growth in yeast
Amino acids are the building blocks of life. We obtain them from the food we eat, and the body uses them to make proteins, which in turn are used for growth, development, and a multitude of other functions. However, before the body can build with the.....»»
