New model helps define optimal temperature and pressure to forge nanoscale diamonds

Nanodiamonds, bits of crystalline carbon hundreds of thousands of times smaller than a grain of sand, have intriguing surface and chemical properties with potential applications in medicine, optoelectronics and quantum computing. To forge these nanoscopic gemstones, researchers expose organic explosive molecules to powerful detonations in a controlled environment. These explosive forces, however, make it difficult to study the nanodiamond formation process, even under laboratory conditions.

Purdue drug discovery aims to find better drug 'fits,' avoid medication tragedies like thalidomide

When a medication doesn't "fit" the body quite right, the results can be devastating. Such is the case for thalidomide, which was prescribed in the 1950s and 1960s as a sedative or hypnotic, even for pregnant women.

Scientists create synthetic prototissue capable of synchronised beating

The discovery, published in Nature Materials, is the first chemically programmed approach to producing an artificial tissue. The findings, which could have major health applications in the future, could see chemically programmed synthetic tissue being used to support failing living tissues and to cure specific diseases.

Study shows what happens when ultrafast laser pulses, not heat, cause a material to change phase

The way that ordinary materials undergo a phase change, such as melting or freezing, has been studied in great detail. Now, a team of researchers has observed that when they trigger a phase change by using intense pulses of laser light, instead of by changing the temperature, the process occurs very differently.

Study finds potential benefits of wildlife-livestock coexistence in East Africa

A study of 3,588 square kilometers of privately owned land in central Kenya offers evidence that humans and their livestock can, in the right circumstances, share territory with zebras, giraffes, elephants and other wild mammals—to the benefit of all.
