Optimization algorithms are pivotal in machine learning and artificial intelligence (AI) in general. For a long time, it has been widely believed that the design/configuration of optimization algorithms is a task that heavily relies on human intelligence and requires customized design for specific problems.

Current building design methods are primarily based on improving the connectivity between components of the structure. In the event of component failure, this connectivity allows the loads that were carried by failed components to be redistributed to the rest of the structural system.

Caltech neuroscientists are making promising progress toward showing that a device known as a brain–machine interface (BMI), which they developed to implant into the brains of patients who have lost the ability to speak, could one day help all such patients communicate by simply thinking and not speaking or miming.

New modeling reveals that low-carbon concrete developed at RMIT University can recycle double the amount of coal ash compared to current standards, halve the amount of cement required and perform exceptionally well over time.

In the battle to build software-driven connected vehicles, General Motors Co. CEO Mary Barra knows the "industry is so fierce, you have to have the very best talent."

Copper cannot be mined quickly enough to keep up with current U.S. policy guidelines to transition the country's electricity and vehicle infrastructure to renewable energy, according to a University of Michigan study.

Many people understand the concept of bias at some intuitive level. In society, and in artificial intelligence systems, racial and gender biases are well documented.

Brain-machine interfaces are devices that enable direct communication between a brain's electrical activity and an external device such as a computer or a robotic limb that allows people to control machines using their thoughts.

Researchers from Kaunas University of Technology (KTU), Lithuania, who contributed to the development of record-breaking solar cells a few years ago have expanded their invention. The self-assembled monolayers can now be applied not only in inverted but also in regular structure perovskite solar cells.

Semiconductors are the foundation of all modern electronics. Now, researchers at Linköping University, Sweden, have developed a new method where organic semiconductors can become more conductive with the help of air as a dopant. The study, published in the journal Nature, is a significant step towards future cheap and sustainable organic semiconductors.

Instead of burning fossil fuels to smelt steel and cook cement, researchers in Switzerland want to use heat from the sun. The proof-of-concept study, published May 15 in the journal Device, uses synthetic quartz to trap solar energy at temperatures over 1,000°C (1,832°F), demonstrating the method's potential role in providing clean energy for carbon-intensive industries.

Research at Uppsala University and Karolinska Institutet could pave the way for a prosthetic hand and robot to be able to feel touch like a human hand. Their study has been published in the journal Science. The technology could also be used to help restore lost functionality to patients after a stroke.

Imagine you and a friend are playing a game where your goal is to communicate secret messages to each other using only cryptic sentences. Your friend's job is to guess the secret message behind your sentences. Sometimes, you give clues directly, and other times, your friend has to guess the message by asking yes-or-no questions about the clues you've given. The challenge is that both of you want to make sure you're understanding each other correctly and agreeing on the secret message.

The electric guitar has been a core element of popular music for much of the past century. Pickups are the components that turn vibrations from the strings into electricity for sound and can be seen as the "heart" of the instrument. Electric guitarists have long known that the magnetic force from pickups affects the quality of their sound and how smoothly the sound transitions, known as timbre.

A study explores the role of platinum in shaping the future of green hydrogen development in China. Hydrogen fuel is one of China's key strategies to achieve national energy security and carbon neutrality. Hydrogen is expected to provide more than 10% of China's total energy supply by 2050, and the country has announced more than 50 large-scale hydrogen projects.

By studying how bubbles form in a drop of biodiesel, researchers at the University of Gothenburg can help future engines get the most energy out of the fuel.

Several tribes have banned South Dakota Gov. Kristi Noem over comments she made about tribal leaders benefitting from drug cartels.

Florida Gov. Ron DeSantis has attacked the "global elite's plan to force the world to eat meat grown in a petri dish."

Amazon's self-driving robotaxi unit Zoox is being investigated by the U.S. government's highway safety agency after two of its vehicles braked suddenly and were rear-ended by motorcyclists.

Johns Dental Laboratories stopped making the Anterior Growth Guidance Appliance last year after a KFF Health News-CBS News investigation into allegations of patient harm.
