The trio's early work took place in 1984 when Hall and Rosbash worked together at Brandeis and  Young  at Rockefeller University to isolate the "period" gene  which controls the circadian rhythm of fruit flies. Hall and Rosbash then showed that the level of the protein encoded by this gene changes in a 24-hour cycle  going up during the day and down at night. They theorized that this protein blocked the activity of the period gene.

PROBLEM: What is the sentiment of the following document towards the entity Nikki Haley ? Callista Gingrich   Nikki Haley  and Scott Brown are all running afoul of federal guidelines on social media while the State Department whistles in the wind.
 US ambassador to the UN Nikki Haley  has  her  staff support  her  personal Twitter account.
 US ambassador to New Zealand Scott Brown  has a gag Twitter account for  his  dog Gracie. And US ambassador-designate to the Vatican Callista Gingrich is tweeting about  her  job before starting in an official capacity. Some of President Donald Trumpâs highest-profile political appointees are running afoul of the governmentâs social media rules  enshrined in the State Departmentâs Foreign Affairs Manual. The rules  pushed through in January after years of internal deliberations  are designed to prevent political appointees from exploiting public office by using their official title to build a massive social media presence and then taking their account with them when they re-enter the private sector or retire. Brown  the short lived former senator from Massachusetts  and Haley  the former governor of South Carolina  both use their personal Twitter accounts for official business alongside their government-owned accounts.
 Haley âs staff also helps service  her  Twitter account  including tasks such as taking photos that are disseminated to  her  more than 770 000 followers.
