Growing biofilms actively alter host environment, new study reveals

Dental plaque, gut bacteria and the slippery sheen on river rocks are all examples of biofilms, organized communities of microorganisms that colonize our bodies and the world around us. A new study led by Penn State researchers reveals exactly how growing biofilms shape their environments and fine-tune their internal architecture to fit their surroundings. The findings may have implications for a wide variety of applications, from fighting disease to engineering new types of living active materials.

Novel hydrogel finds new aptamers, or ‘chemical antibodies,’ in days

One double-helix strand of DNA could extend six feet, but it is so tightly coiled that it packs an entire sequence of nucleotides into the tiny nucleus of a cell. If that same DNA was instead split into two strands and divided into many, many short pieces, it would become trillions of uniquely folded 3D molecular structures, capable of bonding to and possibly manipulating specifically shaped molecules — if they’re the perfect fit.

Soft tissue restoration, blood vessel formation focus of $3M grant

Soft tissue restoration, blood vessel formation

By Mariah R. Lucas

The ability to regenerate and pattern blood vessels, the literal lifelines extending deep into soft tissues, remains an elusive milestone in regenerative medicine. Known as tissue revascularization, stimulating blood vessel growth and pattern formation in damaged or diseased tissues could accelerate the field of regenerative medicine, according to Penn State researchers.
