Fars News Agency quoted an Iranian Foreign Ministry spokesman as saying that if other parties fail to fulfill some commitments, the entire memorandum of understanding could be jeopardized.

Fox News reported US Vice President Vance said Iran negotiations are progressing smoothly and he expects to travel to Switzerland in the next few days.

Researchers at Anhui University and the University of Science and Technology of China used a femtosecond-laser composite manufacturing process for fiber-integrated devices to fabricate a three-dimensional microtweezer on the tip of a commercial optical fiber, published in Nature. The device delivers output forces more than 100,000 times those of conventional optical tweezers and enables high-precision, low-damage, programmable 3D manipulation of micron-scale targets, precise assembly of complex microstructures, single-cell manipulation and micro-sampling inside ~100-micron confined spaces. Authors cite application relevance for micro-manipulation, microsystems assembly, life-science handling and minimally invasive medical procedures.
