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.

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.

Scientists capture first-ever video of body's safety test for T-cells

For the first time, immunologists from The University of Texas at Austin have captured on video what happens when T-cells—the contract killers of the immune system, responsible for wiping out bacteria and viruses—undergo a type of assassin-training program before they get unleashed in the body. A new imaging technique that allowed for the videos, described today in the journal Nature Communications, holds promise for the fight against autoimmune disorders such as Type 1 diabetes.

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.

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.

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.
