GUALALA, Calif. (Reuters) - Tranquil images of the Pacific Ocean taken by a drone show that California's kelp forests may be making a comeback after years of depletion, bringing good news in the fight against climate change.
    Kelp, which reduces global warming by soaking up carbon dioxide from the air via photosynthesis, has died off dramatically along Northern California's coast, with one study calculating a loss of more than 95% since 2013 due to rising sea temperatures and disease.
    But a team from environmental group Nature Conservancy has spotted signs of a partial recovery of kelp forests during surveys off the coast of Mendocino and Sonoma counties by drone.

By AI Trends Staff     As the  US Navy  strives to get to a 355-ship fleet by 2034, part of a 30-year plan the Navy outlined in 2019, it is finding it economical to use underwater autonomous vehicles. They meet many of the requirements of larger submarines at a fraction of the cost.     For example, the Navy awarded Boeing a $43-million contract to build four Orca Extra Large Unmanned Undersea Vehicles (XLUUVs) last year, described in a release from  USNI News .      Boeing based its winning Orca XLUUV design on its Echo Voyager unmanned diesel-electric submersible. The 51-foot-long submersible is launched from a pier and can operate autonomously while sailing up to 6,500 nautical miles without being connected to a manned mother ship, according to the Navy.   In military spending terms, the versatility of the Orca at the price is “fairly unheard of in military spending,” according to an account in  The National Interest . The nearest equivalent was cited as the Navy’s Littoral Com

(Reuters) - A Canadian regulator on Tuesday asked for information from the public on telecom company Rogers Communications Inc's planned C$20 billion ($16 billion) purchase of Shaw Communications Inc to check for competition concerns.

The regulator on Tuesday asked market participants and Canadians to come forth with information that could assist the regulator's probe on whether the deal will reduce or prevent competition. The Competition Bureau said its review was ongoing and no conclusions have been made. ... Read More on Datafloq
