The U.S. law dates to 1851, but it has its origins in 18th century England, Davies said. It was designed to encourage the shipping business. Every country with a shipping industry has something similar on the books. 215

The tower began undergoing a major renovation project in July 2017. Within weeks, workers began reporting burning throats, breathing issues and coughs. Court documents allege that city officials ignored their concerns, only vacating the building after the County Air Pollution Control District found measurable levels of asbestos in January 2018. Exposure to asbestos can lead to serious health conditions, including the deadly mesothelioma lung cancer."I don't know in 20 years if I'm going to get sick or not," said Stephanie Teel, 39, who worked in the building as part of the Fire-Rescue Department. "Did that exposure — that they said was nothing — make me be where in 20 years when I'm still fairly young, my family is burying me?"Teel said experienced firefighters spotted the asbestos but city officials did nothing. The City Attorney's office said it would respond through the courts. Maria Severson, representing the class of 550 workers on the case, said it's about long-term protection."They need to know that if they leave the city and they ultimately come down with a lung-related disease that the city is going to take care of them," she said. The building's owner said after the 2018 incident it worked with tenants and regulatory agencies to address the concerns surrounding the tower. Teel has since transferred to a position in the mayor's office. 1367

The researchers weren't necessarily looking for this neutron star. Rather, it was happenstance as they searched for gravitational waves."At Green Bank, we're trying to detect gravitational waves from pulsars," said Maura McLaughlin, study author and Eberly Distinguished Professor of physics and astronomy at West Virginia University. "In order to do that, we need to observe lots of millisecond pulsars, which are rapidly rotating neutron stars. This is not a gravitational wave detection paper but one of many important results which have arisen from our observations."They were able to measure its mass because of a white dwarf companion star that warped the space around both stars. This warping acted as a way to accelerate the pulsar's pulses through space. They could learn the mass of the white dwarf and neutron star this way through the "Shapiro Delay.""Neutron stars are as mysterious as they are fascinating," said Thankful Cromartie, a graduate student at the University of Virginia and Grote Reber pre-doctoral fellow at the National Radio Astronomy Observatory in Charlottesville, Virginia. "These city-sized objects are essentially ginormous atomic nuclei. They are so massive that their interiors take on weird properties. Finding the maximum mass that physics and nature will allow can teach us a great deal about this otherwise inaccessible realm in astrophysics."Due to their mysterious nature, astronomers still want to answer more questions about neutron stars and this unique one could help them. They want to know if crushed neutrons become a type of "superfluid," what the breakdown looks like and where the actual tipping point lies when gravity takes over."The orientation of this binary star system created a fantastic cosmic laboratory," said Scott Ransom, study co-author and an astronomer at the National Radio Astronomy Observatory. "Neutron stars have this tipping point where their interior densities get so extreme that the force of gravity overwhelms even the ability of neutrons to resist further collapse. Each 'most massive' neutron star we find brings us closer to identifying that tipping point and helping us to understand the physics of matter at these mind-boggling densities." 2221

The Senate unanimously voted and confirmed Brown in June, the Air Force stated.Brown replaces Gen. David L. Goldfein, who retired.Brown is the second Black officer to sit on the Joint Chiefs of Staff since Gen. Colin Powell, who was chairman from 1989 to 1993, the Wall Street Journal reported. 294

The PSA Flight 182 Historical Committee continues to work with local officials to find a permanent location in the neighborhood for a memorial plaque -- one already exists at the San Diego Air and Space Museum -- without infringing on property rights or causing a public safety hazard. 285
