Scientists have revealed for the first time the natural weapon used by marigolds to protect tomato plants against destructive whiteflies.
Researchers from Newcastle University's School of Natural and Environmental Sciences, carried out a study to prove what gardeners around the...
The human body is made up of 30 to 40 trillion cells, a large and complex network of blood cells, neurons, and specialized cells that make up organs and tissues. Until now, figuring out which mechanisms control communication between...
How are reptiles capable of generating such a diversity of bright colors? And how is it possible that within a single population of the same species, different individuals exhibit strikingly different coloration patterns? In a new paper published in...
The symbiosis of plants and fungi has a great influence on the worldwide spread of plant species. In some cases, it even acts like a filter. This has been discovered by an international team of researchers with participation from...
University of California, Berkeley, synthetic biologists have engineered brewer's yeast to produce marijuana's main ingredients—mind-altering THC and non-psychoactive CBD—as well as novel cannabinoids not found in the plant itself.
Feeding only on sugar, the yeast are an easy and cheap...
DNA activity can change without changing the sequence of the DNA segment itself. Gene activation and inactivation can be the basis for how species produce unique individuals. Some processes that change gene activity are well understood in the context...
Grocery store aisles are stocked with products that promise to kill bacteria. People snap up those items to protect themselves from the germs that make them sick. However, new research from Washington University in St. Louis finds that a...
Bacteria in the gut do far more than help digest food in the stomachs of their hosts, they can also tell the genes in their mammalian hosts what to do.
A study published today in Cell describes a form of...
A team of biologists, physicists and mathematical modellers in Cambridge have studied the genetic activity of over 100,000 embryonic cells to establish the molecular blueprint of mouse early embryo development. This new research provides fundamentally important information on how...
Scientists have discovered that grasses are able to short cut evolution by taking genes from their neighbours. The findings suggest wild grasses are naturally genetically modifying themselves to gain a competitive advantage.
Understanding how this is happening may also help...
From fathers to children, the delivery of hereditary information requires the careful packing of DNA in sperm. But just how nature packages this DNA to prepare offspring isn't clear. Using new technology to reveal the 3-D organization of DNA...
