The team of Denis Réale, Professor in the Department of Biological Sciences at Université du Québec à Montréal, recently published some remarkable research findings. Reconstructing the genetic…

Mixotrophs are species of algae that act as "plants" when they produce their own food and as “animals” when they eat other plants. Wanderson Carvalho from the University of Kalmar is studying these…

Stem cell biology takes another exciting leap forward as scientists report that normal tissue cells can be reprogrammed to exhibit many of the properties that are characteristic of embryonic stem…

A team of researchers from Arizona State University, Purdue University and the Norwegian University of Life Sciences has discovered evidence that honeybees have adopted a phylogenetically old…

Like hobos on a train, HIV, the virus that causes AIDS, uses a pre-existing transport system to leave one infected cell and infect new ones, Hopkins scientists have discovered. Their findings,…

It could be an artist’s depiction of someone’s stomach before and after a rather decadent meal. But it is a 3-D cryoelectron microscope reconstruction of the cross-section of a virus, before and…

The basic Keller explant is a rectangle of dorsal mesendoderm and ectoderm from an early-gastrula-stage Xenopus laevis embryo. It is ~60° to 90° wide, extending from the bottle cells to the animal…

“When we began the Human Genome Project, we anticipated it would take 15 years to sequence the 3 billion base pairs and identify all the genes,” said Dr. Richard Gibbs, director of the Human Genome…

Many insects living in northern climates don't die at the first signs of cold weather. Rather, new research suggests that they use a number of specialized proteins to survive the chilly months. These…

Inhaling oxygen is only the first step in a long journey through the nooks and crannies of the body. The oxygen is then transported via the blood to all cells in the body. The same goes for…
