There's no question that our species has had a dramatic impact on the planet's physical environment, particularly over the last few centuries, with the rise of modern industry, transportation, and infrastructure. But as new ...

Chemistry trick paves way for safer diabetes medication

New research from the University of Copenhagen points to an entirely new approach for designing insulin-based pharmaceuticals. The approach could open the door for more personalized medications with fewer side effects for ...

Five-dimensional black hole could 'break' general relativity

Researchers have shown how a bizarrely shaped black hole could cause Einstein's general theory of relativity, a foundation of modern physics, to break down. However, such an object could only exist in a universe with five ...

Internally coupled ears enable directional hearing in animals

Humans use the time delay between the arrival of a sound wave at each ear to discern the direction of the source. In frogs, lizards and birds the distance between the ears is too small. However, they have a cavity connecting ...

Rapidly building arteries that produce biochemical signals

Duke engineers have developed a technique to make artificial arteries that naturally produce biochemical signals vital to their functions. The technique is also ten times faster than current methods for tissue engineering ...

What makes a bacterial species able to cause human disease?

An international team of scientists, led by researchers at University of California, San Diego School of Medicine and the J. Craig Venter Institute (JCVI), have created the first comprehensive, cross-species genomic comparison ...
