Moving microswimmers with tiny swirling flows

Moving microswimmers with tiny swirling flows

A rotating particle creates a flow that pushes swimming bacteria into a spiral-shaped halo around the center. The discovery helps scientists understand the interaction of microswimmers and could help prevent films from forming in microfluidic devices such as labs-on-a-chip.

What do we really know about Dino DNA?

What do we really know about Dino DNA?

Ever since finding that soft tissue can preserve in dinosaur fossils, paleontologist Mary Schweitzer has been asked the «Jurassic Park» question – will we ever be able to find original dinosaur DNA? And if so, could we someday recreate these awesome animals? The answers to these questions can get pretty complicated, so Dr. Schweitzer has […]

GNU Free Documentation License, Version 1.2 New research from the Howard Hughes Medical Institute transforms the current view that metamorphosis in fruit flies, whereby larvae change into adults, consists of two separate stages. The study, to be published in the journal eLife, shows that while larval […]

Credit: Mstyslav Chernov/commons.wikimedia.org Sri Lanka is a global biodiversity hotspot with many forms of wildlife found nowhere else on the planet. Unique subspecies such as the Sri Lankan leopard and the largest Asian elephant are an important tourist draw for a country finding its feet after decades of civil war. While wildlife enriches daily life, […]

Credit: Zernicka-Goetz Lab, University of Cambridge Genetic ‘signatures’ of early-stage embryos confirm that our development begins to take shape as early as the second day after conception, when we are a mere four cells in size, according to new research led by the University of Cambridge and EMBL-EBI. Although they seem […]
