A 3-D approach to stop cancer in its tracks

Every day, roughly 100 billion new cells are created inside the human body. These cells join trillions of older cells to form the tissues and organs we rely on to stay alive. Sometimes when a cell is created, a mutation occurs ...

Measuring molecular interactions

ETH Zurich researchers have used a new approach to discover previously unknown interactions between proteins and small metabolic molecules in bacterial cells. The technique can also be used to test the effect of medications.

Scientists reveal double life of sunflower enzyme

Scientists have explained how a protein-cutting enzyme can join the ends of proteins together, creating protein circles; a finding with immediate applications in producing therapeutic drug treatments that is published in ...

Electrochemistry flushes out antibiotic-resistant proteins

EPFL scientists, working in association with Valais Hospital in Sion and Fudan University in Shanghai, have developed a method for analyzing bacteria that – for the first time ever – lets doctors quickly see exactly which ...

Did water-based life originate without water?

When trying to understand the origins of life on Earth, researchers run into a paradox: while water is an indispensable solvent for all known life forms that exist today, water also inhibits the formation of string-like chains ...

Botulinum-type toxins jump to a new kind of bacteria

Enterococci are hardy microbes that thrive in the gastrointestinal tracts of nearly all land animals, including our own, and generally cause no harm. But their ruggedness has lately made them leading causes of multi-drug-resistant ...

Versatile C. difficile blocker

Clostridium difficile (C. difficile) infection is the leading cause of hospital-acquired diarrhea, causing nearly a half million infections in the United States each year. Recurrence after treatment with antibiotics is common ...

Vitamin C in the body can be tracked by fluorescence

Vitamin C is best known as a nutrient. In high enough doses, however, vitamin C also shows potential against many cancers, according to recent studies. To successfully develop vitamin C (chemically named ascorbic acid) as ...

Revolutionizing drug discovery with RNA in the spotlight

The rise of antibiotic resistance among common infectious bacteria is a worrisome health threat that has many scientists looking for a solution. Jennifer Hines, Ph.D., professor of chemistry and biochemistry at Ohio University, ...
