Imagine sitting in a packed stadium for a pivotal football game—tens of thousands of people are using mobile phones at the same time, perhaps video chatting with friends or posting photos on social media. The radio frequency signals being sent and received by all these devices could cause interference, which slows device performance and drains batteries.

Designing devices that can efficiently block unwanted signals is no easy task, especially as 5G networks become more universal and future generations of wireless com...

New astronomical measurements in the infrared range have led to the identification of a heretofore unknown class of asteroids. An international research team including geoscientists from Heidelberg University has succeeded in characterizing these small planets using infrared spectroscopy.

They are located in the asteroid belt between Mars and Jupiter and are—similar to the dwarf planet Ceres—rich in water. According to computer models, complex dynamic processes shifted these asteroids from the outer regions of our solar system into today’s asteroid belt shortly after their creation.

With an equatorial diame...

Once thought incapable of encoding proteins due to their simple monotonous repetitions of DNA, tiny telomeres at the tips of our chromosomes seem to hold a potent biological function that’s potentially relevant to our understanding of cancer and aging.

Reporting in the Proceedings of the National Academy of Sciences, UNC School of Medicine researchers Taghreed Al-Turki, Ph.D., and Jack Griffith, Ph.D...

A research team led by Dr. Yong-hun Kim and Dr. Jeong-Dae Kwon has successfully developed the world’s first neuromorphic semiconductor device with high-density and high-reliability by developing a thin film of lithium-ion battery materials. They achieved this by producing ultra-thin lithium ions, a key material of lithium-ion batteries that have been in the spotlight recently, and combining it with two-dimensional nano-materials...
