'One child called the robot "my little brother"': Can assistance tech become part of the family?
2025-08-08
What happens to a social robot after it retires?
Four years ago, we placed a small owl-shaped reading robot named Luka into 20 families’ homes. At the time, the children were preschoolers, just learning to read. Luka’s job was clear: scan the pages of physical picture books and read them aloud, helping children build early literacy skills.
That was in 2021. In 2025, we went back — not expecting to find much. The children had grown. The reading level was no longer age-appropriate. Surely, Luka’s work was done.
Instead, ...
Small but mighty: A biomimetic idea takes flight
2025-08-08
When Singapore celebrated its 50th year of independence in 2015, a team of student researchers led by Associate Professor Foong Shaohui from Singapore University Technology and Design (SUTD) embarked on an ambitious challenge: to design and build a drone capable of 50 minutes of sustained flight. At the time, most hobbyist quadcopters could barely manage half of that. The SG50 Multi-Rotor Drone project succeeded, but to fly that long, the craft had to be large, complex, and heavy.
A decade on, Assoc Prof Foong has reached new heights in his drone research—this time by going small and pursuing a completely different ...

Molecules in the spotlight: Snapshots reveal the eternal dance of particles
2025-08-07
FRANKFURT. Most of us find it difficult to grasp the quantum world: According to Heisenberg’s uncertainty principle, it’s like observing a dance without being able to see simultaneously exactly where someone is dancing and how fast they’re moving – you always must choose to focus on one. And yet, this quantum dance is far from chaotic; the dancers follow a strict choreography. In molecules, this strange behavior has another consequence: Even if a molecule should be completely frozen at absolute zero, it never truly comes to rest. The atoms it is made of perform a constant, never-ending quiet dance driven by so-called ...
What drives anaphylactic response in food allergies
2025-08-07
New research in mice reveals that food-induced anaphylaxis is driven by distinct immune pathways involving inflammatory lipids called leukotrienes. The findings, published across two separate studies, identify genetic and cellular factors that influence susceptibility to severe allergic reactions and point to the potential of the drug Zileuton to block this life-threatening response. Food allergies arise when the immune system mounts an exaggerated response to certain proteins found in foods. This reaction is typically driven by Immunoglobulin E (IgE) antibodies, which recognize dietary allergens and activates mast cells throughout the body. In severe ...
A thoughtful approach to governing emerging quantum technologies
2025-08-07
