Plasmonics and photonics have been drawing attention in both academia and industry due to their use in an extensive range of applications, one of which includes optical sensing. The development of optical sensing technology not only contributes to the scientific research community as a versatile tool, but also offers substantial commercial value for smart city and Internet of Things (IOT) applications due to its energy efficiency, lightweight, small size and suitability for remote sensing. Reinforcing its significance, Scientific American identified plasmonic sensing as one of the top 10 emerging technologies of 2018.

'Foldable' PC? Lenovo ThinkPad laptop screen bends in half like a book
Samsung has gained a lot attention lately for its Galaxy Fold hybrid smartphone/tablet, though given the recent display snags that have prompted a delay in the product's release, not necessarily for all the right reasons.

Framework improves 'continual learning' for artificial intelligence
Researchers have developed a new framework for deep neural networks that allows artificial intelligence (AI) systems to better learn new tasks while "forgetting" less of what it has learned regarding previous tasks. The researchers have also demonstrated that using the framework to learn a new task can make the AI better at performing previous tasks, a phenomenon called backward transfer.

Toy transformers and real-life whales inspire biohybrid robot
Drawing inspiration from biology and the toy shelf, researchers at Thayer School of Engineering at Dartmouth College and City University of Hong Kong have developed a swimming robot with a light-controlled cellular engine that can perform highly-targeted drug delivery.

Cyber attacks are rewriting the 'rules' of modern warfare—and we aren't prepared for the consequences
Governments are becoming ever more reliant on digital technology, making them more vulnerable to cyber attacks. In 2007, Estonia was attacked by pro-Russian hackers who crippled government servers, causing havoc. Cyber attacks in Ukraine targeted the country's electricity grid, while Iran's nuclear power plants were infected by malware that could have led to a nuclear meltdown.

New machine learning algorithm can predict age and gender from just your Twitter profile
A new "demographic inference" tool developed by academics can make predictions based solely on the information in a person's social media profile (i.e. screen name, biography, profile photo, and name). The tool—which works in 32 languages—could pave the way for views expressed on social media to be factored in to popular survey methods.

Nanoscale sculpturing leads to unusual packing of nanocubes
From the ancient pyramids to modern buildings, various three-dimensional (3-D) structures have been formed by packing shaped objects together. At the macroscale, the shape of objects is fixed and thus dictates how they can be arranged. For example, bricks attached by mortar retain their elongated rectangular shape. But at the nanoscale, the shape of objects can be modified to some extent when they are coated with organic molecules, such as polymers, surfactants (surface-active agents), and DNA. These molecules essentially create a "soft" shell around otherwise "hard," or rigid, nano-objects. When the nano-objects pack together, their original shape may not be entirely preserved because the shell is flexible—a kind of nanoscale sculpturing.

Ernst Haeckel: Pioneer of modern science
"By ecology, we understand the whole science of the organism's relationship with the surrounding outside world, which includes in a broader sense all 'existential conditions'. These are partly organic and partly inorganic in nature; both the former and the latter are, as we have previously shown, of utmost importance for the form of the organisms, because they force them to adapt to them."

Metals influence C-peptide hormone related to insulin
Metals such as zinc, copper and chromium bind to and influence a peptide involved in insulin production, according to new work from chemists at the University of California, Davis. The research is part of a new field of "metalloendocrinology" that takes a detailed look at the role of metals in biological processes in the body.

Lunar South Pole Atlas—a new online reference for mission planners
The Lunar and Planetary Institute (LPI), managed by Universities Space Research Association (USRA), has compiled and made available an atlas of the Moon's south pole. Given NASA's recent direction to implement Space Policy Directive-1 landing astronauts at the south pole by 2024, the LPI has compiled a series of maps, images, and illustrations designed to provide context and reference for those interested in exploring this area.
