Subatomic particles known as neutrinos travel in a straight line from their cataclysmic origins and don't interact with other particles, making them extremely difficult to detect. Now a neutrino observatory in Antarctica has detected a particular neutrino, and with the help of NASA's Fermi Gamma-Ray Space Telescope, has succeeded in tracing the particle's origin to a blazar 3.7 billion years ago.
The USS Mustin and USS Benfold sailed through the Taiwan Strait over the weekend, a transit that's normally routine but has become sensitive because of tensions between China and the US involving trade and the status of Taiwan.

The Navy's newest unmanned helicopter has completed its first trial for compatibility with littoral combat ships and other platforms. The MQ-8C Fire Scout flew from the LCS USS Coronado to run through combat simulations testing its target identification, intelligence and surface warfare capabilities.
A Congressional Research Service report questions the Navy's rush to develop a new class of frigate. The report focuses on capabilities and suggests the new vessel may not fill in existing gaps or, alternatively, might duplicate capabilities the service already has.
A vast sandbar left in the San Jacinto River by Hurricane Harvey will be addressed as part of a major flood control project in the Houston area. Efforts to restore 2 miles of the river to their pre-Harvey condition should indicate to the state the need for more comprehensive sediment and sand control planning, writes the Houston Chronicle editorial board.
Nonpoint source water pollution is the top challenge to water quality in Nevada, and now the state has $1 million in federal money to address the problem. State, local and tribal governments are being invited to apply for funds if they can produce a nonfederal match of at least 50%.
