Parallel alignment of dressing fibers accelerates wound healing
A team of researchers from Singapore has reported the development of a skin-mimicking scaffold by parallelly aligning nanofibers made up of a mixture of polycaprolactone (PCL) and gelatin that enhances wound healing. Their research has recently been.....»»
Novel polymer toughens up and changes color upon mechanical stress
A fascinating and crucial ability of biological tissue, such as muscle, is self-healing and self-strengthening in response to damage caused by external forces. Most human-made polymers, on the other hand, break irreversibly under enough mechanical st.....»»

The world"s first integrated quantum communication network
Chinese scientists have established the world's first integrated quantum communication network, combining over 700 optical fibers on the ground with two ground-to-satellite links to achieve quantum key distribution over a total distance of 4,600 kilo.....»»
Study demonstrates the quenching of an antiferromagnet into high resistivity states
Antiferromagnetism is a type of magnetism in which parallel but opposing spins occur spontaneously within a material. Antiferromagnets, materials that exhibit antiferromagnetism, have advantageous characteristics that make them particularly promising.....»»
Performance fiber with color-changing coating makes mechanical stress visible
High-performance fibers that have been exposed to high temperatures usually lose their mechanical properties undetected and, in the worst case, can tear precisely when lives depend on them. For example, safety ropes used by fire brigades or suspensio.....»»
Fewer tourists meant less money for wildlife during the pandemic – but there"s an alternative
"Nature is healing" read social media posts at the outset of the pandemic, as birdsong replaced the drone of traffic during lockdown. But for wildlife conservation in Africa, the reality was very different. Anti-poaching operations in protected areas.....»»
