Scientists find a new way to determine the age of diamonds, and what made them

Diamonds are sometimes described as messengers from the deep Earth; scientists study them closely for insights into the otherwise inaccessible depths from which they come. But the messages are often hard to read.

"The most important film director alive"

The visual poet of Nature

Werner Herzog (born 5 September 1942) is a German film director, screenwriter, actor, writer, poet, and opera director. Herzog is considered part of the New German Cinema. His feature films often focus attention on ambitious protagonists with impossible dreams, people with unique talents in marginal and obscure fields, or individuals who are in conflict with nature or society. His later work is mostly centered on documentaries where he describes the profound and magical relation between science, nature, culture, and the individual. These are not regular films about natural phenomena but brave and genuine journeys into subjectivity and the human role in natural processes. Herzog obtained world fame with his exceptional perspective on both mainstream and alternative topics, and his decisive manner of work.

Nanorobots could target cancers and clear blood clots

The future of internal medicine

Tiny nano-sized robots and vehicles that can navigate through blood vessels to reach the site of a disease could be used to deliver drugs to tumours that are otherwise difficult to treat.

Once injected or swallowed, most drugs rely upon the movement of body fluids to find their way around the body. It means that some types of disease can be difficult to treat effectively in this way.

One aggressive type of brain tumour known as glioblastoma, for example, kills hundreds of thousands of people a year. But because it produces finger-like projections into a patient's brain tissue that damage the blood vessels around them, it is hard for drugs to reach the tumour site.

'If you inject particles into the body, they will follow the blood,' said Professor Daniel Ahmed, who is currently leading the Acoustic Robotics Systems Lab at ETH Zurich in Switzerland.

Instead, scientists are turning to nanodevices – tiny robots and vehicles – to deliver drugs around the body in a controllable way. But first, they have to figure out how to drive them.

New law of physics helps humans and robots grasp the friction of touch

Discovery advances a range of AI technologies

Although robotic devices are used in everything from assembly lines to medicine, engineers have difficulty accounting for the friction that occurs when robots grip objects -- particularly in wet environments. U.S. National Science Foundation-funded researchers have discovered a law of physics that accounts for this type of friction and may advance a wide range of robotic technologies.

"Our work opens the door to creating more reliable and functional devices in applications such as telesurgery and manufacturing," said Lilian Hsiao, a chemical and biomolecular engineer at North Carolina State University and corresponding author of a paper on the work.
