| New technique reveals immune cell motion Posted: 19 Dec 2014 01:06 PM PST Neutrophils, cells recruited by the immune system to fight infection, need to move through a great variety of tissues. New research shows how neutrophils move through confined spaces in the body. A new system can mimic tissues of different densities and stiffness, enabling improved development and testing of drugs. |
| Europe shows that humans and large predators can share the same landscape Posted: 19 Dec 2014 10:01 AM PST The recovery of large carnivores in Europe is a great success for nature conservation. At one third of mainland Europe, at least one species of large carnivore is present, according to a new article. It is an excellent example that humans and carnivores can share the same landscape, say researchers. |
| Yellowstone's thermal springs: Their colors unveiled Posted: 19 Dec 2014 10:01 AM PST Researchers have created a simple mathematical model based on optical measurements that explains the stunning colors of Yellowstone National Park's hot springs and can visually recreate how they appeared years ago, before decades of tourists contaminated the pools with make-a-wish coins and other detritus. |
| Gene critical for proper brain development discovered Posted: 19 Dec 2014 07:41 AM PST A genetic pathway has been found that accounts for the extraordinary size of the human brain. The research team has identified a gene, KATNB1, as an essential component in a genetic pathway responsible for central nervous system development in humans and other animals. |
| A vegetarian carnivorous plant Posted: 19 Dec 2014 07:40 AM PST Carnivorous plants catch and digest tiny animals in order and derive benefits for their nutrition. Interestingly the trend towards vegetarianism seems to overcome carnivorous plants as well. The aquatic carnivorous bladderwort, which can be found in many lakes and ponds worldwide, does not only gain profit from eating little animals but also by consuming algae and pollen grains. |
| Cell-associated HIV mucosal transmission: The neglected pathway Posted: 18 Dec 2014 12:45 PM PST Scientists are challenging dogma about the transmission of the human immunodeficiency virus type 1 (HIV-1). Most research has focused on infection by free viral particles, while this group of researchers proposes that HIV is also transmitted by infected cells. |
