A new fruit wash removes pesticides and extends shelf life

University of British Columbia researchers have developed a natural, biodegradable wash that removed up to 96% of pesticide residue from fruit and slowed browning and moisture loss. This could mean safer apples, grapes and ...

A nanoscale robotic cleaner can hunt, capture and remove bacteria

Tiny robots—around 50 times smaller than the diameter of a human hair—open up fascinating possibilities: they enable the controlled manipulation of objects far too small for human hands. This brings us closer to a long-standing ...

Using menstrual blood-derived particles to treat osteoarthritis

New research by an interdisciplinary team in Lithuania has revealed a promising and unconventional approach to cartilage regeneration. Using extracellular vesicles derived from menstrual blood stromal cells, the researchers ...

Momentum-engineered photonic states make bulk silicon shine

An international team of researchers, led by scientists from the University of California, Irvine, has demonstrated a fundamentally new way to make silicon emit light—overcoming one of the most persistent limitations in modern ...

Structural color can now be printed with an inkjet printer

While traditional printer pigments fade and most structural color can't be printed, Kobe University material engineer Sugimoto Hiroshi has been working on nothing short of a revolution in the way color is produced.
