Researchers at Pontifical Catholic University of Rio Grande do Sul have recently carried out a study aimed at evaluating people's perceptions of geometric features, personalities and emotions presented in video sequences with virtual humans. Their study, outlined in a paper pre-published on arXiv, merges computer science tools with psychology research practices.

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.

Stay safe in the sun by knowing how to protect your skin
DEAR MAYO CLINIC: Do spray sunscreens work as well as sunscreen lotions, and do I need to buy different sunscreen for my kids than what I use myself?

Here's why your internet may be delivered by a drone someday soon
As the pilotless flying wing came in for a landing, winds suddenly picked up. Facebook Inc.'s Aquila drone—powered by the sun and wider than a Boeing 737 jetliner—struggled to adjust. Just before landing, part of the right wing broke off.

Children describe technology that gives them a sense of ambiguity as 'creepy'
Many parents express concerns about privacy and online safety in technology designed for their children. But we know much less about what children themselves find concerning in emerging technologies.

Researchers teach robots handwriting and drawing
An algorithm developed by Brown University computer scientists enables robots to put pen to paper, writing words using stroke patterns similar to human handwriting. It's a step, the researchers say, toward robots that are able to communicate more fluently with human co-workers and collaborators.

Stop gambling with black box and explainable models on high-stakes decisions
As the buzzwords "machine learning" continue to grow in popularity, more industries are turning to computer algorithms to answer important questions, including high-stakes fields such as healthcare, finance and criminal justice. While this trend can lead to major improvements in these realms, it can also lead to major problems when the machine learning algorithm is a so-called "black box."

New AI sees like a human, filling in the blanks
Computer scientists at The University of Texas at Austin have taught an artificial intelligence agent how to do something that usually only humans can do—take a few quick glimpses around and infer its whole environment, a skill necessary for the development of effective search-and-rescue robots that one day can improve the effectiveness of dangerous missions. The team, led by professor Kristen Grauman, Ph.D. candidate Santhosh Ramakrishnan and former Ph.D. candidate Dinesh Jayaraman (now at the University of California, Berkeley) published their results today in the journal Science Robotics.

Particulate matter from aircraft engines affects airways
In a unique, innovative experiment, researchers under the leadership of the University of Bern have investigated the effect of exhaust particles from aircraft turbine engines on human lung cells. The cells reacted most strongly to particles emitted during ground idling. It was also shown that the cytotoxic effect is only to some extent comparable to that of particles from gasoline and diesel engines.

Helping robots remember: Hyperdimensional computing theory could change the way AI works
The Houston Astros' José Altuve steps up to the plate on a 3-2 count, studies the pitcher and the situation, gets the go-ahead from third base, tracks the ball's release, swings ... and gets a single up the middle. Just another trip to the plate for the three-time American League batting champion.

Visualizing microglia in brain tissue with a fluorescence turn-on substrate
Part of the immune system in the brain is made up of so-called microglia cells. Korean and Singaporean researchers have now developed a fluorescent probe that specifically labels this type of macrophage. The cells were visualized in cell culture and in the live brains of rodents. As detailed in the journal Angewandte Chemie, a gene product expressed in microglia triggers the probe into a fluorescing state, which is detected through live-cell fluorescence imaging.

A work patch for better nursing home care
Placing a loved one in a nursing home can be a traumatic experience for the entire family with concerns about the care and attention they will receive. Imagine if those concerns were eased, simply by some changes in the way the schedules are done for the staff at that facility.

New clinical pathway for cancer patients leads to better outcomes, lower health care costs
A new clinical pathway for cancer patients at Christiana Care Health System's Helen F. Graham Cancer Center & Research Institute is improving their quality of life, providing better health outcomes and delivering lower heath care costs, according to a study published in the May 2019 issue of the Journal of Clinical Pathways.

Study finds scientific reproducibility does not equate to scientific truth
Reproducible scientific results are not always true and true scientific results are not always reproducible, according to a mathematical model produced by University of Idaho researchers. Their study, which simulates the search for that scientific truth, will be published Wednesday, May 15, in the journal PLOS ONE.

Can sound protect eagles from wind turbine collisions?
Every year, bald and golden eagles are killed when they inadvertently fly into wind turbine blades. One possible way to prevent these deaths is to chase the birds away with acoustic signals—sound. To determine what types of sounds are most effective in deterring the birds, researchers at the University of Minnesota and their colleagues tested the behavioral responses of bald eagles to a battery of both natural and synthetic acoustic stimuli.
