  • Scientists in Canada discover a new species of dinosaur.
  • The species is named Thanatotheristes degrootorum, which stands for "Reaper of Death"
  • The dinosaur lived about 79 million years ago.

A new dinosaur species was found in Alberta, Canada. Related to Tyrannosaurs, the Thanatotheristes degrootorum is the oldest dinosaur ever found in the country, roaming its lands about 79 millions years ago.

The newly-discovered species, the first such find in the last 50 years, shares a lineage with the fearsome T.rex, which came about 11 million years later. Thanatotheristes degrootorum, whose name translates ominously as the "reaper of death," had the length of two cars and the height of about 2.4 meters. It lived during the Cretaceous period, when it prayed on herbivorous beasts like the horned dinosaur Xenoceratops and Colepiocephale, who head is shaped like a dome. Remains of these two species were also found at the same fossil site called the Foremost Formation. Millions of years ago it was a plain with swamps on the coast of the Western Interior Seaway, an inland sea that stretched from the Arctic Ocean to the Gulf of Mexico.

The research was led by Jared Voris, a University of Calgary PhD candidate, who co-authored with study with the research group leader Professor Darla Zelenitsky.

"This animal would have absolutely been an imposing creature in the ecosystem that it lived in and it would very likely have been the apex predator," Voris explained, adding that "It was really nice to have some sort of name that encapsulated that kind of behaviour."

The Thanatotheristes was indeed the top predator among the three dinosaur species found in southern Alberta so far. The others were more likely to be herbivores. Professor Zelenitsky called T.rex's distant cousin as "relatively rare in the ecosystems," said Professor Zelenitsky," adding "These were probably only a few per cent of the animals."

The scientists are looking for find other specimen of the dinosaur still out there, hoping it will fill out the picture of prehistoric life in the region.

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.

Surprising Science
  • Radiation is one of the biggest threats to astronauts' safety during long-term missions.
  • C. sphaerospermum is known to thrive in high-radiation environments through a process called radiosynthesis.
  • The results of the study suggest that a thin layer of the fungus could serve as an effective shield against cosmic radiation for astronauts.

  • Bruce Lee would have turned 80 years old on November 27, 2020. The legendary actor and martial artist's daughter, Shannon Lee, shares some of his wisdom and his philosophy on self help in a new book titled "Be Water, My Friend: The Teachings of Bruce Lee."
  • In this video, Shannon shares a story of the fight that led to her father beginning a deeper philosophical journey, and how that informed his unique expression of martial arts called Jeet Kune Do.
  • One lesson passed down from Bruce Lee was his use and placement of physical symbols as a way to help "cement for yourself this new way of being, or this new lesson you've learned." By working on ourselves (with the right tools), we can develop the skills necessary to rise and conquer new challenges.
