Abstract: A genetically modified mouse is provided, wherein the mouse expresses an immunoglobulin light chain repertoire characterized by a limited number of light chain variable domains. Mice are provided that express just one or a few immunoglobulin light chain variable domains from a limited repertoire in their germline. Methods for making bispecific antibodies having universal light chains using mice as described herein, including human light chain variable regions, are provided. Methods for making human variable regions suitable for use in multispecific binding proteins, e.g., bispecific antibodies, and host cells are provided. Bispecific antibodies capable of binding first and second antigens are provided, wherein the first and second antigens are separate epitopes of a single protein or separate epitopes on two different proteins are provided.

Abstract: A toy assembly for retaining and launching a miniature boomerang from an upper limb of the body which limb includes a wrist, hand and fingers, the assembly consisting of the combination of the boomerang, a support member attachable to the upper limb, and a platform mounted on top of the support member to retain the boomerang in a first storage position and further to provide for the shifting of the boomerang to a second launching position wherein launching is accomplished by flicking a wing of the boomerang with a finger of the opposite upper limb on which the support member is positioned.

Abstract: A combustion chamber may include an upper and a lower chamber. The chambers may be separable to aid in loading fuel and removing spent fuel. The cross-section of the upper combustion chamber may be less than the cross-section of the lower section. Charcoal or other biomass fuel may be added into the lower combustion chamber and may be supported by a grate. Oxygen may be fed into the combustion chamber through a plurality of apertures that may be substantially shielded from direct line of site of the fuel bed. The upper combustion chamber may further include an annular constriction, to aid in constricting the view factor between the cooking vessel and the fuel bed. The constriction may also aid in radiating energy back to the fuel bed.

Abstract: Disclosed herein are devices and methods that aid in providing high efficiency stoves for developing and underdeveloped regions. In some embodiments, the stoves are plancha-style stoves comprise cast iron planchas that are more durable and efficient that existing stoves. The plancha-style stoves, described herein may comprise a combustion chamber comprising an inlet, a stack chamber comprising an inlet and an outlet; a gas path chamber, comprising a ceiling and a floor, wherein the ceiling is defined by a removable plancha cooking surface having a substantially planar upper surface and a lower surface; a chimney box; and a chimney. In many embodiments, the stack chamber defines a cross-sectional area that is larger than the cross-sectional area of the inlet to the combustion chamber to prevent smoke from escaping the combustion chamber through the inlet.
