Apple Air Tags can be helpful if you've lost your keys or wallet. But police are now warning people to be careful because they've received reports of Air Tags being used to follow people without them knowing it.
The quarter-sized gadget can go anywhere and connect to your phone to locate the item you can't find.

Researchers at Purdue University have recently developed new transistors based on indium oxide, a semiconductor that is often used to create touch screens, flatscreen TVs and solar panels. These transistors, introduced in a paper published in Nature Electronics, were fabricated using atomic layer deposition, a process that is often employed by transistor and electronics manufacturers.

Researchers around the world are continually finding new ways to prolong Moore's law. Now, Purdue researchers have found another means to this end: using an atomic layer deposition technique for indium oxide-based transistors.

Purdue University Professor Mark Lundstrom says almost every week he is talking with technology companies that are considering building a plant in various states, including Indiana, to manufacture microchips and other advanced systems. He spent a career working and teaching in the field of electrical and computer engineering and is a leading expert in semiconductor devices and nanoscale transistors. Lundstrom says the microelectronics industry is quickly changing and a global shortage of microchips is just a part of the puzzle.

But challenges await, including technical issues, regulatory barriers and many miles of highway.

Making sense of ML performance and benchmark data is an ongoing challenge. In light of last week’s release of the most recent MLPerf (v1.1) inference results, now is perhaps a good time to review how valuable (or not) such ML benchmarks are and the challenges they face. Two researchers from Purdue University recently tackled this issue in a fascinating blog on ACM SIGARCH – An Academic’s Attempt to Clear the Fog of the Machine Learning Accelerator War.

An innovation by Purdue University researchers could help the semiconductor industry design transistors that are smaller, use less power and switch from on to off at smaller applied voltages. As a result, the innovation could lead to better and more powerful central processing unit generations, which can compute more operations with less energy.

Researchers have found that a material can mimic the sea slug’s most essential intelligence features. The discovery is a step toward building hardware that could help make AI more efficient and reliable for technology ranging from self-driving cars and surgical robots to social media algorithms.

“Through studying sea slugs, neuroscientists discovered the hallmarks of intelligence that are fundamental to any organism’s survival,” says Shriram Ramanathan, a professor of materials engineering at Purdue University. “We want to take advantage of that mature intelligence in animals to accelerate the development of AI.”

In this study, researchers used titanium nitride to achieve HHG in refractory metals for the first time. In the future, this could pave the way to focusing the radiation down to nanoscale for use in nanomachining, nanofabrication and medical applications, as well as HHG enhancement for the generation of frequency combs for the next generation of nuclear clocks.

Efficient farming and agricultural decision-making will increasingly depend on usable farm-level data and software. But just because something is technically possible doesn’t mean it is simple to figure out. Working through the headaches to get data and systems to work well together is one of the chief aims of a group of engineers and scientists at Purdue University.
