Findings allow scientists to study neural stem cells' behavior without harming them

Genetic changes pose risks to human immunity

Research team from University of Houston find that the light-activated gold nanoparticles destroy potentially deadly bacterial cells in seconds

New class of robots can be controlled in a less invasive way through the use of light

Problem: The topic of technology transfer raises caution with many laboratory managers of analytical laboratories. In routine analysis laboratories, such as QA/QC, the need for continued support of established high performance liquid chromatography (HPLC) methods can significantly outweigh the potential advantages of method modernization, making it exceptionally problematic or undesirable to adopt more modern liquid chromatography (LC) assays or instrumentation such as U(H)PLC ultra-high performance LC.

Problem: Nearly 40 years after its introduction, western blotting continues to be a powerful method for protein quantitation. Arguably, finding the right antibody to detect the protein of interest is the technique’s most critical and challenging step.

Glove boxes go by many different names and are used for many purposes. However, their essential attribute is the ability to maintain a completely separate environment from ambient. Glove boxes are completely closed compartments ranging in size from a few cubic feet to several hundred cubic feet and differ from other safety enclosures in two significant respects: users can introduce articles into glove boxes and manipulate them inside through ports fitted with gloves, and glove boxes typically use a specialized atmosphere.

Nearly any biologist can now use some form of this microscopy

Automated liquid handling (ALH) systems span the range from semi-automated multichannel pipettors to room-sized systems. The industry is trending toward versatile, modular ALH systems—seemingly for every budget. Likewise, instrumentation, software, and methods have followed the trend toward greater user accessibility.

Scientists have developed biodegradable polymer grafts that should grow to be just the right size and shape to fix the spinal column
