Fillings are essentially the only treatment option widely available for cavities, but now researchers from China have created a new peptide-based coating that can prevent cavities from forming.

A new method presents an alternative strategy to fecal transplants or pro-biotics.

A new study from UCL may have brought us a step closer to understanding how life arose. The team may have solved a long-standing chicken-and-egg riddle related to how different types of peptides and proteins interact to give rise to life.

MS is a debilitating disease that damages myelin, the sheaths protecting neurons in the nervous system, leading to impaired motor skills and cognition. Now, researchers at Melbourne University have developed a synthetic peptide that helps regenerate myelin, potentially slowing progression of MS.

With bacteria rapidly evolving resistance to our best antibiotics, scientists are searching high and low for new ones. Researchers have now found that a potent peptide normally used for digestion has strong antimicrobial effects, and could form the base of new drugs.

Cancer cells have gone rogue and are dividing unchecked, and now Australian researchers have designed a new molecule that may put a stop to that. It targets a protein called PCNA, a donut-shaped structure that plays a key role in cell division, which could lead to a new class of cancer treatments.

We've already heard about a probiotic pill, an Alzheimer's-treatment drug and a mineral-replacing toothpaste that could treat or even prevent cavities. Now, scientists at the University of Washington have developed a natural product of their own that may do the job.

With bacteria becoming ever more resistant to our best antibiotics, scientists are searching high and low for new ones in nature. Now a team from Australia and Spain have discovered a promising peptide in the venom of the South American Rattlesnake.

One of the biggest biological mysteries is how life arose out of non-living molecules. To find out, a Georgia Tech team has recreated some of the conditions common to a pre-life Earth, and discovered that drying and rewetting the primordial soup lets key peptides form quickly and relatively easily.

Whether it’s a whiff of wildflowers, or the aroma of some bizarre fruit cocktail, that freshly shampooed smell doesn't last long after stepping out of the shower. Researchers from EPFL may now have found the answer to longer-lasting scents that can stay in the hair for up to 24 hours.

ScienceIn 2008, researchers analyzed samples of protein preserved in T-rex bone, and came to the conclusion that the dinosaurs were closely related to modern ostriches. Now, palaeontologists have taken another look and found it is ostrich, thanks to some modern contamination.

Frog mucus might seem like the kind of flu remedy a witch doctor would suggest, but researchers have found that certain peptides excreted by frogs can fight off human flu strains. As such, they could be used as emergency stand-ins during flu outbreaks when regular vaccines aren’t available.
