Researchers have found a more accurate way to calculate dog age in human years, songs from different cultures exhibit universal patterns, big retailers are pushing costs of tariffs onto suppliers.

These, and more, are the newsworthy stories from this past week.

Science and Environment

  • Researchers have come up with a much more accurate formula to assess dog age in human years.

    Human Years = 16 ln(Dog Years) + 31, where ln is the natural logarithm.

    Dogs seem to age very quickly in the first part of their life (which is why the age of young pups seem very weird translated into human years), but their ageing process slows down massively compared to that of humans.

Health and Society

  • No matter where they are from, similar-sounding songs are associated with the same activities, such as infant care, healing, love and dance.

    Songs from cultures around the world exhibit some universal patterns, according to a new study that hints at the psychology behind music’s broad appeal. The new research suggests a fundamental property underlying music’s uncanny hold on the mind, several evolutionary biologists and musicologists said. People listen to more music than ever, streaming some 611 billion songs on demand last year.

Business and Economics

  • Big retailers like Bed Bath and Beyond, Target, and TJX Brands are refusing to accept tariff price increases from their brand suppliers, telling the companies they will have to either eat the tariff costs or find another buyer.

    This forces the costs of President Trump’s trade war with China down to smaller businesses that can hardly afford them, while the big companies keep the impact of tariffs at bay.

  • Alphabet’s Google said it will stop allowing highly targeted political ads on its platform, rolling out a ban in the U.K. within a week (ahead of a Dec. 12 general election), in the EU by the end of the year and in the rest of the world Jan. 6.

    The policy will bar targeting based on users’ interests inferred from browsing or search history, though targeting based on age, gender and location will be allowed, and political advertisers will still be able to display ads based on the content of the page a user is viewing.

  • The U.S. no longer will consider Israeli settlements to be illegal under international law, Secretary of State Mike Pompeo said.

    The move formalizes the Trump administration’s treatment of the West Bank and shifts decades of U.S. policy. The new policy drew swift praise from Israelis and condemnation from Palestinians, European officials and rights groups who say the stance could hinder peace efforts.
