Colloidal quantum dots make LEDs shine bright in the infrared

The ideal optoelectronic semiconductor material would be a strong light emitter and an efficient charge conductor to allow for electrical injection in devices. These two conditions, when met, can lead to highly efficient ...

Bioactive novel compounds from endangered tropical plant species

A Japan-based research team led by Kanazawa University has isolated 17 secondary metabolites, including three novel compounds from the valuable endangered tropical plant species Alangium longiflorum. A newly isolated compound, ...

Could villains clone themselves to take over the world?

If asked about clones, most people think of evil sci-fi characters. However, in real life, the word "clone" often has broader, far more positive applications. Just as office workers replicate documents by using copy machines, ...

Molecular guardians monitor chromosomes during cell division

One of the worst things that can happen to a cell is to end up with the wrong number of chromosomes. This can happen if something goes wrong during cell division, and it can lead to infertility, miscarriages, birth defects, ...

How cells build different antennae to sense their surroundings

Cells communicate with each other and with the environment using tiny antennae, called cilia, that emit and receive signals, including sound, smell and light information. Some of these antennae can also move, and are altered ...
