Sound waves replace human hands in petri dish experiments

Mechanical engineers at Duke University have demonstrated a set of prototypes for manipulating particles and cells in a Petri dish using sound waves. The devices, known in the scientific community as "acoustic tweezers," ...

Next frontier in bacterial engineering

From bacteria-made insulin that obviates the use of animal pancreases to a better understanding of infectious diseases and improved treatments, genetic engineering of bacteria has redefined modern medicine. Yet, serious limitations ...

The paradox of dormancy: Why sleep when you can eat?

Why do predators sometimes lay dormant eggs, which are hardy, but take a long time to hatch and are expensive to produce? That is the question that researchers from Singapore University of Technology and Design (SUTD) set ...

Scientists develop 'Twitter' for cells

Computational biologists led by Prof. Yvan Saeys (VIB-UGent Center for Inflammation Research) developed a new bioinformatics method to better study communication between cells. This method, called NicheNet, helps researchers ...

The tips of a plant design its whole shape

Plants grow throughout their entire life. This is due to a small structure at the tip of the plant's shoots known as the meristem. This is the control center for the maintenance of stem cells—which can be converted into ...

Optical switch illuminates cell development

Combining light and a protein linked to cancer, researchers at Princeton University have created a biological switch to conduct an unprecedented exploration of cellular development in the embryo.

Animal embryos evolved before animals

Animals evolved from single-celled ancestors, before diversifying into 30 or 40 distinct anatomical designs. When and how animal ancestors made the transition from single-celled microbes to complex multicellular organisms ...
