The Double Asteroid Redirection Test (DART) was a NASA space mission aimed at testing a method of planetary defense against near-Earth objects (NEOs). [4] [5] It was designed to assess how much a spacecraft impact deflects an asteroid through its transfer of momentum when hitting the asteroid head-on. [6]
Diffusing Alpha-emitters Radiation Therapy or DaRT is an alpha-particle-based radiation therapy for the treatment of solid tumors. [ 1 ] [ 2 ] This therapy was developed at Tel Aviv University in Israel, by Professors Itzhak Kelson and Yona Keisari.
The incidence rate of peripheral neuropathy has been demonstrated to decrease when lower therapeutic radiation dosing levels are used. [21] [1] A similar nerve injury, Radiation-induced Brachial Plexopathy (RIBP), may occur secondary to breast radiation therapy. [23] Studies on RIBP have observed the brachial plexus' radiosensitivity.
Femoral nerve dysfunction, also known as femoral neuropathy, is a rare type of peripheral nervous system disorder that arises from damage to nerves, specifically the femoral nerve. [1] Given the location of the femoral nerve, indications of dysfunction are centered around the lack of mobility and sensation in lower parts of the legs.

Nerve compression syndrome, or compression neuropathy, or nerve entrapment syndrome, is a medical condition caused by chronic, direct pressure on a peripheral nerve. [1] It is known colloquially as a trapped nerve, though this may also refer to nerve root compression (by a herniated disc, for example).
Immunoglobulin and steroids are the first line choices for treatment. [citation needed] In severe cases of CIDP, when second-line immunomodulatory drugs are not efficient, autologous hematopoietic stem cell transplantation (HSCT) is sometimes performed. The treatment may induce long-term remission even in severe treatment-refractory cases of CIDP.
NASA's DART mission was a success. Images taken by satellite show plumes from the asteroid impact, but it could take weeks to monitor for changes in the asteroid’s trajectory.
