Long-Qing Chen, a renowned professor at Penn State, has been awarded the Humboldt Research Award for his significant contributions to materials science and engineering. He plans to establish international collaborations and learn about European cultures through a one-year research project in Germany.
Research by Robert Cialdini reveals six universal principles of influence: reciprocity, commitment, social proof, authority, liking and scarcity. These principles can be used ethically to change behavior and achieve desirable outcomes.
Researchers at Virginia Tech have made breakthrough discovery on optimizing dew droplet size to improve efficiency of removing condensation. By fine-tuning surface nanoscopic topography, they found that droplets can be made small enough to jump off surfaces as early as 2 micrometers.
Biologist Carl-Philipp Heisenberg has been awarded an ERC advanced grant to study the interplay between gene regulatory networks and physical processes in embryonic development. His research will focus on gastrulation, a critical phase of embryonic development where cells are transformed into distinct layers.

Research at Michigan State University found that even brief interruptions can significantly impact accuracy on complex tasks. The study, which involved 300 participants and a sequence-based procedure, discovered that interruptions lasting just three seconds doubled the error rate. This finding has significant implications for professio...
Researchers create a dynamic gel made of DNA that mechanically responds to stimuli in the same way cells do. The DNA gel's movement runs on ATP, allowing for faster and stronger mechanics than other smart gels based on synthetic polymers.
A 'nanoclutch' has been designed to regulate the speed of nanomotors, allowing for stepless control. The device uses electrowetting forces and charged carbon nanotubes to transmit torque between tubes.
Researchers are developing a new traffic modeling system that incorporates individual human behavior traits to forecast transportation needs. The VASTO model simulates habitual patterns with real-time reactions and will allow planners to see what would happen if traffic is rerouted or construction is proposed.
Researchers explore scaling relationships of slow slip events and compare them to similar laws for earthquakes, highlighting the need for further study to understand fault mechanics. A newly defined propeller-like geometry of southern San Andreas Fault may require re-thinking ground motion assessments.
A new method visualizes mechanical forces on cell surfaces in real-time, providing detailed view of forces as they occur. The technique has potential to diagnose and treat diseases related to cellular mechanics.
Researchers from North Carolina State University developed a system to measure brand personality appeal (BPA), allowing companies to understand how favorably their brand is viewed by consumers. The BPA framework assesses three components: favorability, originality, and clarity, grading brands on their overall appeal.
Bicycle balance relies on a mixture of physical effects linked to mass distribution, not gyroscopic or caster effects. Researchers built a riderless bike that balanced itself without these effects.
Researchers at JILA disprove the popular theory that DNA's backbone needs a small gap or loose ends to extend by 70% when subjected to 65 picoNewtons of force. The new study uses a novel test structure to demonstrate that the mechanism behind overstretching is the same for both nicked and intact DNA molecules.
The National Science Foundation has recognized three projects with Breakthrough Awards: an artificial retina restoring sight to the blind; a system using controlled rocking to help buildings withstand earthquakes; and a low-cost medical microscope for detecting malaria-infected blood cells.
A new study has shed light on the inner mechanics of the thymus, revealing its role in negative selection, which prevents immune cells from attacking the body's own tissues.
