Lomekwi is an archaeological site located on the west bank of Lake Turkana in Kenya. It is an important milestone in the history of human archaeology. An archaeological team from Stony Brook University in the United States discovered traces of Lomekwi by chance in July 2011, and made substantial progress with four years of in-depth excavations.

GW151226 was a gravitational wave signal detected by the LIGO observatory on 25 December 2015 local time (26 Dec 2015 UTC). On 15 June 2016, the LIGO and Virgo collaborations announced that they had verified the signal, making it the second such signal confirmed, after GW150914, which had been announced four months earlier the same year, and the third gravitational wave signal detected.
