Kawasaki Heavy Industries has succeeded in a flight test of the unmanned compound helicopter ” K-RACER ” at the Taiki-cho Multipurpose Air Park in Hokkaido . We demonstrated the technology of a ...

Most small molecules are unable to rapidly traverse the outer membrane of Gram-negative bacteria and accumulate inside these cells, making the discovery of much-needed drugs against these pathogens ...

The performance gap between compound bows and new crossbows seems to be widening exponentially. In the last few years of crossbow testing, we reviewed bows — the Ravin R500, Tenpoint Nitro 505, and ...

Scientists don’t know the limits of chemical space—the collection of all possible molecules—but a new analysis concludes chemists have discovered new compounds in that space at an exponential rate ...

Researchers are able to test in parallel the effects of over 1500 active substances on cell metabolism. Their analysis also led to the discovery of previously unknown mechanisms for known medications.

A vile-smelling but versatile class of compounds may find a role in more chemistry laboratories with the introduction of easily made, inoffensive versions. Isonitriles, chemicals characterized by a ...
