A new AI can create scientific theories like a human scientist
Quirks and Quarks9:05A new AI can create scientific theories like a human scientist
Artificial intelligence has proved quite beneficial in sorting via substantial amounts of information to discover patterns and correlations, but till now it has taken a human to create theories to make sense of these patterns. University of Maryland Baltimore County associate professor Tyler Josephson was component of the analysis group that created an AI technique that can use mathematical and logical reasoning to make a theory primarily based on genuine-planet information, analogous to the way a human scientist does. This analysis was published in Nature Communications.

Canadian astronaut and former Canadian Forces fighter pilot Jeremy Hansen has been chosen as 1 of the 4 crewmembers who will fly on NASA’S Artemis II mission which is planned to orbit the moon roughly a year and a half from now. CBC science reporter Nicole Mortillaro spoke with Hansen the day soon after the announcement of his trip.

Understanding the secret of bear hibernation could support humans steer clear of blood clots
Quirks and Quarks8:23Understanding the secret of bear hibernation could support humans steer clear of blood clots
When humans are immobilized for lengthy periods of time, we run the threat of building potentially severe blood clots. Hibernating bears, having said that, never face any such challenges. Ole Frøbert, an invasive cardiologist from Örebro University in Sweden and Aarhus University in Denmark, who research hibernating brown bears thinks he’s unlocked the secret to how they steer clear of blood clots. When bears go into hibernation, they make significantly less of a precise protein that acts like the glue in blood clots — a element that also kicks in soon after about 27 days in humans when they drop their mobility. Their analysis was published in the journal Science.

Medieval monks watching the moon supplied beneficial climate information
Quirks and Quarks8:03Medieval monks watching the moon supplied beneficial climate information
Medieval monks in Europe produced observations that have supplied scientists now with clues about the volcanic activity that impacted the climate and may well have influenced the start off of the Small Ice Age. Monks noted the adjustments in colour and brightness of the moon, especially through lunar eclipses. Atmospheric scientists, which includes Matthew Toohey from the University of Saskatchewan, have an understanding of these adjustments to be the outcome of aerosols created through eruptions. His analysis was published in Nature.
A view on the womb — a new book appears at the neglected science of the uterus
Quirks and Quarks15:32A view on the womb – a new book appears at the neglected science of the uterus
Journalist-turned-midwife Leah Hazard had no doubt about the significance of the womb, because no human could be born with no 1. But the extra she discovered about the uterus, the extra she was shocked about what scientists and healthcare experts never know about it — especially when it comes to its function outdoors of reproduction. She explores what we know and what we nevertheless have to have to find out about the uterus in her new book, Womb: The Inside Story of Exactly where We All Started.

Quirks Query: How would the Earth be diverse if it had under no circumstances collided with the object that designed the moon?
Quirks and Quarks2:12How would the Earth be diverse if it had under no circumstances collided with the object that designed the moon?
A listener asks: The moon was formed when the Earth collided with a little planet. How would the Earth be diverse if this collision under no circumstances occurred? For the answer we hear from Elena Hyde, an assistant professor of physics and astronomy and the Director of the Allan I. Carswell Observatory and York University in Toronto.
