A new type of ferroelectric polymer that is exceptionally good at converting electrical energy into mechanical strain holds promise as a high-performance motion controller or “actuator” with great potential for applications in medical devices, advanced robotics, and precision positioning systems, according to a team of international researchers led by Penn State.

Mechanical strain, how a material changes shape when force is applied, is an important property for an actuator, which is any material that will change or deform when an external force such as electrical energy is applied...

Our Milky Way galaxy is an awe-inspiring feature of the night sky, viewable with the naked eye as a hazy band of stars stretching from horizon to horizon.

For the first time, the IceCube Neutrino Observatory in Antarctica has produced an image of the Milky Way using neutrinos—tiny, ghost-like astronomical messengers.

In research published June 29 in the journal Science, the IceCube Collaboration—an international group of more than 350 scientists—presents evidence of high-energy neutrino emission coming from the Milky Way.

We have not...

Recurrent bouts of systemic lupus erythematosus, marked by the body’s immune system attack of its own tissues, closely tracked with measureable upticks in growth in the gut of a certain species of bacteria.

New research from NYU Grossman School of Medicine shows that bacterial blooms of the gut bacterium Ruminococcus blautia gnavus occurred at the same time as disease flare-ups in five of 16 women with lupus of diverse racial backgrounds studied over a four-year period. Systemic lupus erythematosus involves damaging inflammation, especially in the kidneys, but also in joints, skin, and blood vessels. Four of these study patients with R...

The new photonic chip enables exponentially faster and more energy-efficient artificial intelligence. Scientists have developed a fast and extremely efficient method for transferring huge amounts of data. The technique uses dozens of frequencies of light to transfer several streams of information over a fiber optic cable simultaneously.

The data centers and high-performance computers that run artificial intelligence programs, such as large language models, aren’t limited by the sheer computational power of their individual nodes...
