Researchers develop novel framework for tracking developments in optical sensors
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.

Changes in subsistence hunting threaten local food security
Scientists with the Universidad San Francisco de Quito and WCS Ecuador Program publishing in the journal BioTropica say that subsistence hunting in Neotropical rain forests—the mainstay of local people as a source of protein and a direct connection to these ecosystems—is in jeopardy from a variety of factors.

Artificial intelligence shines light on the dark web
Beneath the surface web, the public form of the internet you use daily to check email or read news articles, exists a concealed "dark web." Host to anonymous, password-protected sites, the dark web is where criminal marketplaces thrive in the advertising and selling of weapons, drugs, and trafficked persons. Law enforcement agencies work continuously to stop these activities, but the challenges they face in investigating and prosecuting the real-world people behind the users who post on these sites are tremendous.

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.

Earliest evidence of the cooking and eating of starch
New discoveries made at the Klasies River Cave in South Africa's southern Cape, where charred food remains from hearths were found, provide the first archaeological evidence that anatomically modern humans were roasting and eating plant starches, such as those from tubers and rhizomes, as early as 120,000 years ago.

Study finds narrowing gender gap in youth suicides
New research from Nationwide Children's Hospital finds a disproportionate increase in youth suicide rates for females relative to males, particularly in younger youth aged 10-14 years. The report, which describes youth suicide trends in the United States from 1975 to 2016, appears this week in JAMA Network Open.

Microsoft alerts hospitals to fix potential security risk
Computer experts inside hospitals were working diligently on Wednesday to address a serious new security vulnerability in older versions of the Windows operating system, which is still used in many health care devices even though Microsoft hasn't actively supported the older software in years.

Making the best of sparse information
New findings reported by LMU researchers challenge a generally accepted model of echolocation in bats. They demonstrate that bats require far less spatial information than previously thought to navigate effectively.

A social perception scheme for behavior planning of autonomous cars
To navigate dynamic environments, autonomous vehicles (AVs) should be able to process all information available to them and use it to generate effective driving strategies. Researchers at the University of California, Berkeley, have recently proposed a social perception scheme for planning the behavior of autonomous cars, which could help to develop AVs that are better equipped to deal with uncertainty in their surrounding environment.

For many HIV+ women, daily survival takes precedence over viral suppression
According to scientists who study women infected with HIV, statistics often paint an impressionist view of the lives of these women that misses the granular detail that tells the real story. The imprecise big picture is that most of this population is doing a good job at suppressing the virus, but facts gathered on the ground show that many struggle with issues of daily living that can make taking a pill to keep HIV at bay difficult.
