Algae-powered soft robot arm uses light to grasp and lift small objects and more — today's student signal.

As we explore the latest developments in science and discovery, it's clear that understanding and adapting to change is a common thread across many fields. In the realm of technology and innovation, researchers are making strides in harnessing the power of nature, as seen in the development of an algae-powered soft robot arm that can grasp and lift small objects using light. This breakthrough showcases the potential for sustainable and eco-friendly solutions in robotics.

Meanwhile, in the social sciences, new studies highlight the importance of understanding human behavior and interactions. For instance, research on bullying in physical education emphasizes the role of student motivation and responsibility in creating a positive environment. Additionally, an analysis of kindergarten redshirting and retention trends during the pandemic reveals significant shifts in this practice. Other studies focus on the environmental impact of human activities, such as the effects of war on the environment and the ways in which data can be used to hold militaries accountable. Even the arts are being re-examined, as researchers investigate what the faces in paintings can tell us about human perception of emotion. Finally, a look at the consequences of drought and rainfall on the ground itself reveals the complex and sometimes destructive relationships between water and the earth, with implications for homeowners and communities.

Today's signal:
• Algae-powered soft robot arm uses light to grasp and lift small objects (phys.org)
• Student motivation and responsibility shown to be key to tackling bullying in physical education (phys.org)
• Holding out or holding back? Kindergarten redshirting and retention shifted sharply during the pandemic (phys.org)
• Data vital in holding militaries accountable for the environmental toll of war (phys.org)
• What faces in paintings can tell us about how we perceive emotion (phys.org)
• Subsidence claims: After drought, ground can shrink, swell or even collapse when it rains—causing damage to homes (phys.org)
