Biodegradable anti-cancer treatment micro-robot

Professor Hongsoo Choi's research team in the Department of Robotics Engineering & DGIST-ETH Microrobot Research Center (DEMRC) at DGIST (President Young Kuk) succeeded in developing a biodegradable micro-robot that can perform ...

Birds around airports may be deaf and more aggressive

Birds around airports are more aggressive and sing as if they have hearing loss. Collaboration between researchers of Manchester Metropolitan University and the Institute of Biology Leiden has led to surprising new findings ...

Space station's data rate increase supports future exploration

NASA recently doubled the rate at which data from the International Space Station returns to Earth, paving the way for similar future upgrades on Gateway, NASA's upcoming outpost in lunar orbit, and other exploration missions. ...

A laser for penetrating waves

The Landau-level laser is an exciting concept for an unusual radiation source. It could efficiently generate so-called terahertz waves, which can be used to penetrate materials, with possible applications in data transmission. ...

Scientists develop filter to suppress radio interference

Researchers from Siberian Federal University and Kirensky Institute of Physics have proposed a new design for a multimode stripline resonator. The use of such resonators allows scientists to create miniature band-pass filters ...

Radio galaxy 3C 236 investigated with LOFAR

Using the LOw Frequency ARray (LOFAR) astronomers took a closer look at the giant radio galaxy 3C 236. The observations, detailed in a paper published July 22 on the arXiv pre-print repository, shed more light on the morphology ...

Technologies for the sixth generation cellular network

Future wireless data networks will have to reach higher transmission rates and shorter delays, while supplying an increasing number of end devices. For this purpose, network structures consisting of many small radio cells ...

Frequency

Frequency is the number of occurrences of a repeating event per unit time. It is also referred to as temporal frequency. The period is the duration of one cycle in a repeating event, so the period is the reciprocal of the frequency. For example, if a newborn baby's heart beats at a frequency of 120 times a minute, its period (the interval between beats) is half a second.
