Scientists have innovated a sustainable method to create electrochemical sensors by laser printing on fallen tree leaves. This technique, which transforms leaf cellulose into functional graphite sensors through pyrolysis, has proven effective in detecting substances like dopamine and paracetamol.

In a feat aimed at understanding how cells move and creating new ways to shuttle drugs through the body, scientists at Johns Hopkins Medicine say they have built a minimal synthetic cell that follows an external chemical cue and demonstrates a governing principle of biology called “symmetry breaking.”

Researchers at Rice University have unlocked the potential to use 3D printing to make sustainable wood structures, offering a greener alternative to traditional manufacturing methods.

Stanford materials engineers have 3D printed tens of thousands of hard-to-manufacture nanoparticles long predicted to yield promising new materials that change form in an instant. This innovative approach, highlighted in Nature Communications, may revolutionize everything from solar panels to computer memory.

Toxic chemicals used to flame-proof plastic materials can be absorbed into the body through skin, via contact with microplastics, new research shows.

A new Netflix documentary, produced by BBC Studios' Science Unit, explores the fascinating reconstruction of the face of a 75,000-year-old female Neanderthal. This ambitious project revealed not only the physical appearance of Neanderthals, but also their cultural practices.

A new 3D printing method uses ice to build a template for artificial blood vessels in engineered tissue. Researchers hope the vessels could eventually be used in artificial organ transplants or drug testing.

USC researchers are pioneering an accessible AI education with a low-cost, customizable “robot friend” kit, aimed at demystifying AI technology for students. This hands-on approach, supported by the National Science Foundation, not only makes learning about robotics, machine learning, and ethics more engaging but also addresses the affordability gap in educational robotics.

Researchers at the Georgia Institute of Technology have developed a light-based means of printing nano-sized metal structures that is significantly faster and cheaper than any technology currently available. It is a scalable solution that could transform a scientific field long reliant on technologies that are prohibitively expensive and slow.

Scientists have developed a sensor made from ‘frozen smoke’ that uses artificial intelligence techniques to detect formaldehyde in real time at concentrations as low as eight parts per billion, far beyond the sensitivity of most indoor air quality sensors.
