That one time a scientist was walking down by the bay and a killer whale said, ‘Hello.’

Alas, much like parrots, they don’t know what they’re saying … it’s just that they can do it, which is still pretty remarkable.

Can killer whales speak human? That may depend on whether you think speaking requires the transmission of meaning, but a new study confirms that killer whales can definitely "speak" the same sounds as humans, imitating words like "hello," "bye bye," and "one, two."

Sounds that humans make while speaking exist far outside the regular range that killer whales, Orcinus orca, usually make. However, killer whales have their own accents and dialects—unique sounds created only within their groups (called pods). If killer whales move pods or are displaced into a different one, the sounds they make to communicate with fellow killer whales adapt to the new environment.

This is key to their ability to mimic human speech. It means they can learn and use new sounds, and actually, depend on doing so for survival


Listen to a killer whale say 'hello!'



In the study, these whales learned to mimic words like "hello," "bye bye," and "one, two." However, as co-author of the study, Josep Call cautioned, "We have no evidence that they understand what their 'hello' stands for."

The story is available in the Proceedings of the Royal Society B, in a paper titled, Imitation of novel conspecific and human speech sounds in the killer whale (Orcinus orca). A simpler version is explained in The Guardian.

This discovery means killer whales join the relatively limited group of creatures that can mimic human speech — some birds, elephants, orangutans, bats, seals, and other cetacean species such as bottlenose dolphins and beluga whales.


COVID-19 amplified America’s devastating health gap. Can we bridge it?

The COVID-19 pandemic is making health disparities in the United States crystal clear. It is a clarion call for health care systems to double their efforts in vulnerable communities.

  • The COVID-19 pandemic has exacerbated America's health disparities, widening the divide between the haves and have nots.
  • Studies show disparities in wealth, race, and online access have disproportionately harmed underserved U.S. communities during the pandemic.
  • To begin curing this social aliment, health systems like Northwell Health are establishing relationships of trust in these communities so that the post-COVID world looks different than the pre-COVID one.

Politics & Current Affairs
  • The Battle of Britain is widely recognized as one of the most significant battles that occurred during World War II. It marked the first major victory of the Allied forces and shifted the tide of the war.
  • Historians, however, have long debated the deciding factor in the British victory and German defeat.
  • A new mathematical model took into account numerous alternative tactics that the German's could have made and found that just two tweaks stood between them and victory over Britain.

The neoliberal era is ending. What comes next?

The next era in American history can look entirely different. It's up to us to choose.

  • The timeline of America post-WWII can be divided into two eras, according to author and law professor Ganesh Sitaraman: the liberal era which ran through the 1970s, and the current neoliberal era which began in the early 1980s. The latter promised a "more free society," but what we got instead was more inequality, less opportunity, and greater market consolidation.
  • "We've lived through a neoliberal era for the last 40 years, and that era is coming to an end," Sitaraman says, adding that the ideas and policies that defined the period are being challenged on various levels.
  • What comes next depends on if we take a proactive and democratic approach to shaping the economy, or if we simply react to and "deal with" market outcomes.
