Recent work has shown that a person's sympathetic arousal can be estimated from facial videos alone using basic signal processing. This opens up new possibilities in the field of telehealth and stress management, providing a non-invasive method to measure stress only using a regular RGB camera. In this paper, we present SympCam, a new 3D convolutional architecture tailored to the task of remote sympathetic arousal prediction. Our model incorporates a temporal attention module (TAM) to enhance the temporal coherence of our sequential data processing capabilities. The predictions from our method improve accuracy metrics of sympathetic arousal in prior work by 48% to a mean correlation of 0.77. We additionally compare our method with common remote photoplethysmography (rPPG) networks and show that they alone cannot accurately predict sympathetic arousal "out-of-the-box". Furthermore, we show that the sympathetic arousal predicted by our method allows detecting physical stress with a balanced accuracy of 90% - an improvement of 61% compared to the rPPG method commonly used in related work, demonstrating the limitations of using rPPG alone. Finally, we contribute a dataset designed explicitly for the task of remote sympathetic arousal prediction. Our dataset contains synchronized face and hand videos of 20 participants from two cameras synchronized with electrodermal activity (EDA) and photoplethysmography (PPG) measurements. We will make this dataset available to the community and use it to evaluate the methods in this paper. To the best of our knowledge, this is the first dataset available to other researchers designed for remote sympathetic arousal prediction.

Physically taxing jobs can hinder one's cognitive health, potentially causing a person's brain to age faster and leave them with a poorer memory as they grow older, a new study suggests. In a study published in the Frontiers in Human Neuroscience in July, researchers surveyed nearly 100 cognitively healthy older adults between ages 60 and 80 years old in order to better understand how stress plays a role in how the human brain ages. Their analysis indicated that adults who reported having higher levels of physical stress in their most recent job were also people who had a smaller hippocampal volume and poorer memory performance. The hippocampus is commonly associated with memory.

In the run-up to important exams, you can find yourself worrying that all the information you've crammed in might not stay in your memory. But it appears that the answer to retaining information may lie away from the books. New research has shown that going for a run can improve the chances of remembering information in exams. In the study, the researchers asked 60 men aged 16-29 to memorize a range of information, from learning a route on a city map to memorizing German-Turkish word pairs. They were then split into three groups: one group played a violent computer game, one went for a run and one spent time outside.

A firm has just unveiled a new family of futuristic suits that give wearers the ability to lift with near superhuman strength and walk great distances without stopping to rest. Panasonic's line of'Iron Man' exoskeletons are designed to assist industrial workers and sportsmen. The Assist Suit AWN-03 gives you the power to repeatedly pick up hefty items without straining your back and the PLN-01 'NINJA' helps you get over the roughest terrain and not break a sweat. Last year, the firm showed a mega exoskeleton resembles the Power Loader exoskeleton suit from the Alien movies (pictured). It had four embedded sensors that would trigger 20 engines, which would reduce human energy.
