Scientists develop inexpensive method to produce E-sail tethers

Thin metallic tethers for Coulomb drag devices that tow satellites and spacecraft can now be produced more easily than before. Scientists of the Finnish Meteorological Institute have developed a method to produce multi-wire ...

How T cells make sure they have quiet time

All cells, like all people, need "quiet" time to function properly, and this is particularly true of T cells, one of the immune system's main weapons. They must be ready for activation at all times, and primed to divide more ...

More than many other auto parts, brake discs are subject to repeated mechanical loads. As a result of this continual abrasion, they produce fine particulate matter, which pose a substantial environmental burden. Now, however, ...

Fabric the reinforcer

Scientists from the National University of Science and Technology (MISIS) have tested experimental composite materials for aircraft brakes, developed by PJSC Aviation Corporation "Rubin." New materials, reinforced by carbon ...

40 countries agree cars must have automatic braking

Forty countries led by Japan and the European Union—but not the U.S. or China—have agreed to require new cars and light commercial vehicles to be equipped with automated braking systems starting as soon as next year, ...
