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.

What's behind the belief in a soulmate?
The United States appears to be in a romantic slump. Marriage rates have plummeted over the last decade. And compared to previous generations, young single people today are perhaps spending more time on social media than actual dating. They are also having less sex.

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.

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.

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."

Machine learning reduces language barriers in global trade, research shows
Machine learning and artificial intelligence have exploded onto the scene in recent years, offering the hope of greater business efficiency. At the same time, researchers have found virtually no empirical evidence supporting the promised strides in labor productivity and economic activity.

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.

Wearable cooling and heating patch could serve as personal thermostat and save energy
Engineers at the University of California San Diego have developed a wearable patch that could provide personalized cooling and heating at home, work, or on the go. The soft, stretchy patch cools or warms a user's skin to a comfortable temperature and keeps it there as the ambient temperature changes. It is powered by a flexible, stretchable battery pack and can be embedded in clothing. Researchers say wearing it could help save energy on air conditioning and heating.

A new era in 3-D printing
In the mid-15th century, a new technology that would change the course of history was invented. Johannes Gutenberg's printing press, with its movable type, promoted the dissemination of information and ideas that is widely recognized as a major contributing factor for the Renaissance.
