MIT researchers developed an extraordinary camera capable of capturing 1 trillion frames per second, fast enough to record the movement of light.

This means it can film events that happen at speeds too quick for the human eye to perceive, like the way light travels through objects. The camera uses a technique called streak camera imaging, allowing scientists to visualize and study ultrafast phenomena.

It’s not your ordinary pocket watch: The researchers showed that, at least under a narrow range of conditions, their clock could beat a benchmark for precision called the “standard quantum limit”—what physicist Adam Kaufman refers to as the “Holy Grail” for optical atomic clocks.

“What we’re able to do is divide the same length of time into smaller and smaller units,” said Kaufman, senior author of the new study and a fellow at JILA, a joint research institute between CU Boulder and NIST. “That acceleration could allow us to track time more precisely.”

The team’s advancements could lead to new quantum technologies. They include sensors that can measure subtle changes in the environment, such as how Earth’s gravity shifts with elevation.

Electronics have tons of gold and copper so we need to consider a global recovery and recycling electronics.

Three photojournalists have created an in-depth report on electronic waste — its negative and… positive… consequences.

What if you could hide an image in plain sight—so well that even the most advanced cameras couldn’t detect it? Imagine encoding visual information using the properties of quantum optics, rendering it invisible to normal imaging technology.

A new type of OLED (organic light emitting diode) could replace bulky night vision goggles with lightweight glasses, making them cheaper and more practical for prolonged use, according to University of Michigan researchers.

A new study led by researchers at the University of Minnesota Twin Cities is providing new insights into how next-generation electronics, including memory components in computers, break down or degrade over time. Understanding the reasons for degradation could help improve efficiency of data storage solutions.

Today’s computers reach their physical limits when it comes to speed. Semiconductor components usually operate at a maximum usable frequency of a few gigahertz – which corresponds to several billion computing operations per second. As a result, modern systems rely on several chips to divide up the computing tasks because the speed of the individual chips cannot be increased any further. However, if light (photons) were used instead of electricity (electrons) in computer chips, they could be up to 1,000 times faster.

Plasmonic resonators, also known as “antennas for light”, are a promising way of achieving this leap in speed. These are nanometre-sized metal structures in which light and electrons interact. Depending on their geometry, they can interact with different light frequencies.

“The challenge is that plasmonic resonators cannot yet be effectively modulated, as is the case with transistors in conventional electronics. This hinders the development of fast light-based switches,” says Dr. Thorsten Feichtner, physicist at Julius-Maximilians-Universität (JMU) Würzburg in Bavaria, Germany.

A pen that can transform Braille into English text has been developed by experts at the University of Bristol.

Braille literacy is frequently reported as being in decline. This is despite visually impaired people often expressing a desire to learn it, and Braille literacy being a highly valued skill by those who are capable. This is often attributed to the lack of available learning resources, particularly away from large urban centers.

The handheld device, which includes a one-centimeter sensor with 19 channels programmed to read Braille, has demonstrated high accuracy in early trials.
