Embryos distinguish vibrational differences, hatching early to snake attacks but not to rain
At the edge of Ocelot Pond, Panama, red-eyed tree frog embryos still in their eggs are about to make a life-or-death decision. The egg clutch, a gelatinous blob clinging to a leaf overhanging the water, has been spied by a bright green parrot snake. In a twinkling, the snake tears a few eggs from the clutch.
With that bite, the embryos start to wiggle frantically. As the snake moves to take another morsel, the embryos rupture their egg capsules, drop into the water, and, as tadpoles, swim away to safety -- hatching one to three days earlier than they would have if left undisturbed.

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...
