Hold off putting up your usual variety of mistletoe – the dwarf mistletoe could soon eclipse its better-known Christmas cousins as the green fertility symbol of choice for holiday party goers. In fact, the discovery of the intimate details of the sex life of the dwarf mistletoe is even getting traditionally staid botanists hot and bothered.
New research shows that the dwarf mistletoe, a member of the same Viscaceae family as the better-known Christmas varieties, is truly worthy of being hung with pride. The stubby variety might be a clumpy green parasite of conifers, but it turns out to have the world’s only water-pump seed ejection system. One that can fire a seed up to a dazzling 20 meters (65 feet). So who are you calling a dwarf now?
"The dwarf species I studied in Manitoba has a gestation period of one-and-a-half years, after which the seed blasts out of the fruit. This extreme buildup of water pressure as a seed dispersal system is rare in the plant world," says Dr. Cynthia Ross, an assistant professor at the University College of the Cariboo in Kamloops, British Columbia.

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur
What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that...
