The NIH has instigated investigations into dozens of scientists over concerns of spying, nearly all linked to China.
Why are missions like OSIRIS-REx bringing pieces of an asteroid back home?
The weird, dumb, and sometimes beautiful mistakes artificial intelligence can make.
Deciding which formula is best for your baby? We look at what science has to say.
Sleepy? Science to the Rescue! Not sleeping enough turning you into a monster? Cutting-edge science helps us understand why. And we sort through the fads to find out, what really works to get more ZZZs. We speak with lab coordinator Pam De Young, sleep researcher Dr. Brady Riedner, and circadian scientist Prof. Russell Foster.

100 years ago this week, scientists shared their observations of how the mass of the bent starlight—an announcement that made Einstein an overnight celebrity.
Ever been called a "jack of all trades, master of none"? The world loves to elevate specialists, people who drill deep into a single topic. Those people are great. But there's a place for generalists too, argues David Epstein. Jacks of all trades are often more successful than specialists. And he's got science to back it up. We talk with Epstein about his latest book, "Range: Why Generalists Triumph in a Specialized World".
The surprising facts you think you know about Venus flytraps.
The Trump Administration has begun a yearlong process to exit the agreement—which would complete the day after the next presidential election.
About 13 times a century, Mercury darts across the blazing disc of the sun. Catch the transit yourself this Monday, November 11th.
Researchers are collecting snapshots of Acadia National Park to supplement satellite data on fall leaf colors.
It’s widely understood that early life adversity has an impact on mental illness and cognitive problems later in life. There are theories as to the mechanisms of how this works, but it’s difficult to test in humans. Tallie Baram is a professor of neurophysiology and biophysics at the UC Irvine department of pediatrics. And she co-authored a recent study in the journal Neuropsychopharmacology with Ali Mortazavi, professor of developmental and cell biology at UC Irvine. Dr. Baram says that imaging studies show changes in brain structure and circuits, and cognitive and emotional tests also demonstrate a change in function. But it’s difficult to study the mechanism, to try to understand how this is happening, because scientists can’t take samples of brain tissue to determine how and when genes are expressed.

These days when we want to know where we are or how to get where we want to go, most of us will pull out a smart phone with a built-in GPS and map app. Some of us old timers might still use an old school paper map from time to time. But we didn't always used to lean so heavily on maps and technology, and in some remote places of the world some people still navigate and wayfind their way without the aid of these tools... and in some cases do better without them. This week, host Rachelle Saunders sits down with Maura O'Connor, journalist and author of the new book "Wayfinding: The Science and Mystery of How Humans Navigate the World" to talk about the new and old ways humans find our way across geography.
Neil deGrasse Tyson sits down with his friend and beloved science communicator Bill Nye to explore how he became the “Science Guy.” With comic co-host Chuck Nice, science communicator Emily Calandrelli, and biological anthropologist Helen Fisher, PhD.

Bonsoir à tous ! Le sujet de l’émission de ce soir est la glace. La glace, c’est un minéral que l’on connaît bien : elle est emblématique de nos calottes polaires, on skie dessus et elle est indispensable à la vie telle qu’on la connaît sous la forme d’eau. Mais si la glace est essentielle sur Terre, elle est aussi présente sur d’autres planètes et satellites, sous plein d’autres états ! Pourquoi la glace est-elle un objet d’étude si important en astrophysique ? Que peut-on apprendre de la glace dans le système solaire et au-delà ? En quoi est-elle intéressante en astrobiologie ? C’est ce que nous allons découvrir grâce Baptiste Journaux, chercheur postdoctoral en Astroglaciologie à la NASA. notes d'émission : https://www.podcastscience.fm/emission/2019/11/06/podcast-science-389-astrobiologie-lunes-glace/
Dr. Jan Cami joins the podcast to discuss the origins of life on Earth, the process of finding other Earth-like planets, and the likelihood that we will ever find company out in the Universe.
For Episode 116 Nujoud Merancy, Exploration Mission Planning Office Chief, returns to the podcast to explain how the mission architecture of the Artemis program differs from Apollo and why it is important to develop a sustainable presence on the Moon.
NASA Goddard Space Flight Center Chief Knowledge Officer Ed Rogers discusses the complex human elements involved in disasters such as the Space Shuttle Columbia accident.
Even though equal access to education remains a challenge, some women prove their worth nevertheless. Half of the ministers in Prime Minister Abiy Ahmed’s cabinet, for example, are women. Once given appropriate access and competitive mindset, women can thrive even in the fields that are more familiar to men, such as forestry.
We live science every single day but we take for granted that the world around us and how we think about it is constantly changing. Join Western Science Speaks every Thursday at 11:30 am on Radio Western 94.9 (http://www.radiowestern.ca/stream) as we talked with geneticists, astronomers, software developers, evolutionary mathematicians, synthetic chemists, geologists, and a variety of other experts working together to answer humanity's most interesting and important questions, because, behind all the formulas and graphs, sciences is our past, our present, and our future.
