Scientists Identify Microbe That Could Help Degrade Polyurethane-Based Plastics A strain of an extremophile group of bacteria is capable of ingesting toxic organic compounds as its sole source of carbon, nitrogen, and energy. There may be a small answer to one of the biggest problems on the planet. German researchers […]

Credit: Joe Angeles/Washington University A new global study reveals the extent to which high-yielding rice varieties favored in the decades since the “Green Revolution” have a propensity to go feral, turning […]

The black patches on the wings of some butterflies are 10 to 100 times darker than everyday black objects. Clockwise from top left: Catonephele numilia, Parides iphidamas, Heliconius doris, Parides sp.

The golden color illustrates the deposition of biocompatible polymers on two genetically targeted neurons at right, sparing neighboring cells. The selective deposition of these polymers, which can be electrically insulating or conductive, makes it possible to modulate target cell properties in living tissues and animals. Blue diamond particles represent the […]

Bees visit pollinator-independent almond blossoms. Credit: Drs. Saez and Negri Pollination by bees is vital even when crops are assumed to be pollinator independent. That’s according to a study co-authored by Ethel Villalobos, a researcher in the University of Hawaiʻi at Mānoa’s College of Tropical Agriculture and Human Resources Department of Plant […]

This new fossil specimen of the worm Utahscolex ratcliffei helped University of Kansas graduate student Anna Whitaker solve a 50-year-old marine-worm mystery. This specimen preserves the everted mouthparts (upper left). The body of the worm is covered of rows of tiny round plates, which were used to redescribe the species. […]

This image shows a fold (shape) that may have been one of the earliest proteins in the evolution of metabolism.

Rutgers researchers have discovered the origins of the protein structures responsible for metabolism: simple molecules […]

Damage (red devils) like drying out, harsh chemicals or heat normally causes proteins to become unstable and lose their proper shape and function (left side, orange). Researchers at the University of Tokyo have characterized Hero proteins (pink, purple, green), long, flexible proteins that protect other proteins (right side, orange). Credit: […]

Immune cells by fluorescence microscopy: Blood stem cells remember a previous attack and produce more immune cells like these macrophages to fight a new infection.
