Study provides new clues to improving chemotherapies

About half of all drugs, ranging from morphine to penicillin, come from compounds that are from—or have been derived from—nature. This includes many cancer drugs, which are toxic enough to kill cancer cells.

Molecular machine exploits motion in a single direction

Life is driven by molecular machines. Found in every cell, these tiny motors convert chemical energy into work to keep the body moving. The invention of synthetic molecular machines, which perform similar jobs to power miniaturized ...

A lightweight carbon nanofiber-based collector

Quan-Hong Yang from Tianjin University and Wei Lv from Graduate School at Shenzhen, Tsinghua University with their co-workers reported a lightweight, high-level nitrogen-doping carbon nanofiber framework as the current collector ...

Robot bloodhound tracks odors on the ground

Bloodhounds are famous for their ability to track scents over great distances. Now researchers have developed a modern-day bloodhound—a robot that can rapidly detect odors from sources on the ground, such as footprints. ...

New beacons light up the interior

LMU's Ralf Jungmann develops modes of microscopy that can resolve cellular structures with dimensions on the order of nanometers. He has now succeeded in imaging actin networks in cells in greater detail than before.

An unlikely marriage among oxides

The term alloy usually refers to a mixture of several metals. However, other materials can also be alloyed. In the semiconductor industry, for instance, oxide and nitride alloys have long been used successfully to tune the ...
