Beer, wine and cheese are classic party foods that couldn’t be made without fermentation. Fermentation is also the key behind food trends like pickling and the tea drink kombucha. In a one-credit intersession course, Johns Hopkins University undergraduates will learn the chemistry behind this biological process, science that will help them understand when they should send back a bottle of wine, what sets a stout apart from a lager, and why some cheeses ooze while others crumble.
Recent news from The Johns Hopkins University

Links to the complete news reports from the nine schools, the Applied Physics Laboratory and other centers and institutes are to the left, as are links to help news media contact the Johns Hopkins communications offices.
In a microscopic feat that resembled a high-wire circus act, Johns Hopkins researchers have coaxed DNA nanotubes to assemble themselves into bridge-like structures arched between two molecular landmarks on the surface of a lab dish. The team captured examples of this unusual nanoscale performance on video.
Scientists’ effort to piece together the genome is taking a significant step forward with a new computerized method that creates more complete and detailed versions of the complex puzzle of life than have ever been produced before.
Bats’ use of echolocation to detect, track and catch prey is well documented. But this Johns Hopkins team is the first to show how the relatively mysterious head and ear movements factor into the hunt.
Whether or not they aced it in high school, human beings are physics masters when it comes to understanding and predicting how objects in the world will behave. A Johns Hopkins University cognitive scientist has found the source of that intuition, the brain’s “physics engine.”
Humans rely on boundaries like walls and curbs for navigation, and Johns Hopkins University researchers have pinpointed the areas of the brain most sensitive to even the tiniest borders.
Johns Hopkins University biologists have found that a protein that plays a key role in the lives of stem cells can bolster the growth of damaged muscle tissue, a step that could potentially contribute to treatments for muscle degeneration caused by old age and diseases such as muscular dystrophy.
Johns Hopkins University researchers are the first to glimpse the human brain making a purely voluntary decision to act.
Johns Hopkins University cognitive scientists say the sharp contrasts in the memory profile of a patient with severe amnesia — her inability to remember facts about pursuits once vital to her life as an artist, musician and amateur aviator, while clearly remembering facts relevant to performing in these domains — suggest conventional wisdom about how the brain stores knowledge is incorrect.
Rats that responded to cues for sugar with the speed and excitement of binge-eaters were less motivated for the treat when certain neurons were suppressed, researchers discovered.
People are intuitive physicists — knowing from birth how objects under the influence of gravity are likely to fall, topple or roll. In a new study, scientists have found the brain cells apparently responsible for this innate wisdom.
People searching for something can find it faster if they know what to look for. But new research suggests knowing what not to look for can be just as helpful.
You’re at a crowded party, noisy with multiple conversations, music and clinking glasses. But when someone behind you says your name, you hear it and quickly turn in that direction. The same sort of thing happens with bats and Johns Hopkins University researchers have discovered how a bat’s brain determines what’s worth paying attention to. The findings, which have implications across animal systems, were published in Proceedings of the National Academy of Sciences.
A public health biologist who is trying to stop the spread of antibiotic-resistant bacteria and pave the way to new treatments for genetic diseases has received the 2016 President’s Frontier Award, a Johns Hopkins University honor that provides $250,000 in research funding. The program was launched last year as part of an expanded university effort to provide more funding to help its faculty move forward with innovative research projects. This year’s recipient is Scott Bailey, an associate professor in the Department of Biochemistry and Molecular Biology, within the university’s Bloomberg School of Public Health.
By studying stroke victims who have lost the ability to spell, researchers have pinpointed the parts of the brain that control how we write words.
While most Down syndrome research has focused on the brain, a new report by Johns Hopkins University biologists uncovers how the disorder hampers the rest of the nervous system that plays a key role in health and longevity.
More than a century ago Pavlov figured out that dogs fed after hearing a bell eventually began to salivate when they heard the ring. A Johns Hopkins University-led research team has now figured out a key aspect of why.
A Johns Hopkins University biologist has led a research team reporting progress in understanding the mysterious shape-shifting ways of stem cells, which have vast potential for medical research and disease treatment.
You’re about to drive through an intersection when the light suddenly turns red. But you’re able to slam on the brakes, just in time.
Johns Hopkins University researchers, working with scientists at the National Institute on Aging, have revealed the precise nerve cells that allow the brain to make this type of split-second change of course. In the latest issue of the journal Nature Neuroscience, the team shows that these feats of self control happen when neurons in the basal forebrain are silenced.
Johns Hopkins University researchers have received an estimated $7.5 million National Institutes of Health grant to clinically test what would be the first treatment to prevent or delay the onset of Alzheimer’s dementia.
Millions of years ago our primate ancestors turned from trees and shrubs in search of food on the ground. In human evolution, that has made all the difference. The change marked a significant step toward the diverse eating habits that became a key human characteristic, and would have made these early humans more mobile and adaptable to their environment.
Researchers at Johns Hopkins University have found molecular evidence of how a biochemical process controls the lengths of protective chromosome tips, a potentially significant step in ultimately understanding cancer growth and aging.
You see a man at the grocery store. Is that the fellow you went to college with or just a guy who looks like him?
One tiny spot in the brain has the answer.
Johns Hopkins University neuroscientists have identified the part of the hippocampus that creates and processes this type of memory, furthering our understanding of how the mind works, and what’s going wrong when it doesn’t. Their findings are published in the current issue of the journal Neuron.
