InAs nanowires are emerging as go-to materials in a variety of applications ranging from optoelectronics to nanoelectronics, yet a consensus on their mechanical properties is still lacking. The mechanical properties of wurtzite InAs nanowires are here investigated via a multitechnique approach, exploiting electron microscopies, ultrafast photoacoustics, and finite element simulations. A benchmarked elastic matrix is provided and a Young modulus of 97 GPa is obtained, thus clarifying the debated issue of InAs NW elastic properties. The validity of the analytical approaches and approximations commonly adopted to retrieve the elastic properties from ultrafast spectroscopies is discussed. The mechanism triggering the oscillations is unveiled. Nanowire oscillations in this system arise from a sudden expansion of the supporting substrate rather than the nanowire itself.
MIT has launched a new academia and industry partnership called the AI Hardware Program that aims to boost research and development.
“A sharp focus on AI hardware manufacturing, research, and design is critical to meet the demands of the world’s evolving devices, architectures, and systems,” says Anantha Chandrakasan, dean of the MIT School of Engineering, and Vannevar Bush Professor of Electrical Engineering and Computer Science.
Microsoft and Hewlett Packard Enterprise (HSE) are working with NASA scientists to develop an AI system for inspecting astronauts’ gloves.
Space is an unforgiving environment and equipment failures can be catastrophic. Gloves are particularly prone to wear and tear as they’re used for just about everything, including repairing equipment and installing new equipment.
Currently, astronauts will send back images of their gloves to Earth to be manually examined by NASA analysts.

Chemical biology professor, Suyang Xu, works to crack the secrets of new states of matter.
Throughout human history, most of our efforts to store information, from knots and oracle bones to bamboo markings and the written word, boil down to two techniques: using characters or shapes to represent information. Today, huge amounts of information are stored on silicon wafers with zeros and ones, but a new material at the border of quantum chemistry and quantum physics could enable vast improvements in storage.
Suyang Xu, assistant professor of chemical biology, is tying quantum mechanical “knots” in topological materials, which may be the key to unlocking the potential of quantum technologies to store and process vast arrays of information and bring game-changing advances in a variety of fields.
A study of more than 120,000 brain scans shows rapid growth before age 2 and accelerating decline after age 50. The results may one day help pick up abnormalities in the developing brain.
The TechCrunch Global Affairs Project examines the increasingly intertwined relationship between the tech sector and global politics.
Geopolitical actors have always used technology to further their goals. Unlike other technologies, artificial intelligence (AI) is far more than a mere tool. We do not want to anthropomorphize AI or suggest that it has intentions of its own. It is not — yet — a moral agent. But it is fast becoming a primary determinant of our collective destiny. We believe that because of AI’s unique characteristics — and its impact on other fields, from biotechnologies to nanotechnologies — it is already threatening the foundations of global peace and security.
The rapid rate of AI technological development, paired with the breadth of new applications (the global AI market size is expected to grow more than ninefold from 2020 to 2028) means AI systems are being widely deployed without sufficient legal oversight or full consideration of their ethical impacts. This gap, often referred to as the pacing problem, has left legislatures and executive branches simply unable to cope.
