Cellular Imaging from Phonon Imaging on a Fiber Probe

Researchers at the University of Nottingham have developed an ultrasonic imaging system, which can be deployed on the tip of a hair-thin optical fibre, and will be insertable into the human body to visualise cell abnormalities in 3D. The new technology produces microscopic and nanoscopic resolution images that will one day help clinicians to examine …

Attosecond Resolution

Researchers demonstrate an on-chip, optoelectronic device capable of sampling arbitrary, low-energy, near-infrared waveforms under ambient conditions with sub-optical-cycle resolution. The detector uses field-driven photoemission from resonant nanoantennas to create attosecond electron bursts that probe the electric field of weak optical waveforms. Using these devices, they sampled the electric fields of ~5 fJ (6.4 MV m−1), few-cycle, near-infrared waveforms …

Holographic Endoscope Potential for In situ Cell Level Diagnostics

Researchers have shown the first far-field endoscope based on multimode fiber. Due to its extended depth of field, the holographic endoscope is capable of imaging macroscopic objects in a wide range of distances. They reached the current technological limits, employing the fastest available spatial light modulator and having an unprecedented control over 17 000 fiber modes. …

High Resolution Imaging Screens Thousands of Genes in a Few Days

Researchers at the Broad Institute of MIT and Harvard and MIT have developed a new method that combines large-scale pooled genetic screens with image-based analysis of cellular behavior. The approach, called optical pooled screens, allows researchers to examine how genes affect complex cellular processes with spatial and temporal resolution, in ways that other pooled screens …

Creating nearly perfect meter sized graphene one hundred times faster

Researchers have achieved a leap forward in graphene production, from a technique that synthesizes a few square centimeters of single-crystal graphene in a couple of hours, to an optimized method that allows the creation of an almost-perfect (over 99.9 percent aligned) 5 × 50 cm2 single-crystal graphene in just 20 minutes. The low production costs, …

Supertiny cameras could shrink from pill size to dust size

The pill-sized cameras in today’s mobile phones may seem miraculously tiny, given that a decade ago the smallest cameras available for retail sale were the size of a pack of cards. Ali Hajimiri of the California Institute of Technology will make far smaller cameras. His team plan to replace them with truly minuscule devices that …

Commercial AI will start sorting through ISIS intelligence data within 6 months

Within six months the US military will start using commercial AI algorithms to sort through its masses of intelligence data on the Islamic State. “We will put an algorithm into a combat zone before the end of this calendar year, and the only way to do that is with commercial partners,” said Col. Drew Cukor. …

Monitoring the world with microsatellites and open source data

Planet Labs uses 149 microsatellites to monitor the pulse of our planet with daily news and imagery, stories, and tech updates. Current satellite imaging only allows us to look at various disconnected locations. Planet’s always-on, daily imagery provides a global monitoring capability never before possible. Frequent satellite imagery is often a critical component to understanding …

Seeing The Invisible With A Graphene-CMOS Integrated Device

EU Graphene Flagship researchers from ICFO (The Institute of Photonic Sciences in Barcelona) have shown that it is possible to integrate graphene into a CMOS integrated circuit. In their paper published in the journal Nature Photonics they combine this graphene-CMOS device with quantum dots to create an array of photodetectors, producing a high resolution image …
