A new twist on two-photon polymerization has been used to deliver objects, including lasers and an elephant, directly into ...

Single-cell functional analysis enables scientists to examine the unique characteristics of each cell within organs, tissues, and cell cultures. Unlike bulk-cell analysis, single-cell analysis allows ...

Every person who has ever been pregnant leaves a biological trace that is far more intimate than a family photo album. During ...

University of Pennsylvania researchers have developed a powerful new investigative tool to reveal how proteins work inside living cells. A technique that enables quick, precise and minimally ...

Scientists have developed a groundbreaking cryo-optical microscopy technique that freezes living cells mid-action, capturing ultra-detailed snapshots of fast biological processes. By rapidly ...

Enzymes help digest food, clean laundry, make perfumes, and build medicines. They also break down toxins in the environment. Because of their wide use, scientists have worked for years to create ...

No modern laboratory is complete without at least one basic microscope, an essential tool for biologists in medical research. Transmitted light methods have largely been replaced by fluorescent ...

Cell migration is a multistep process essential to various physiological functions, including immune cell movement and embryonic development, as well as pathological conditions like tumor metastasis.
