Big Picture Science for Monday August 29, 2016 - DIY Diagnosis












Big Picture Science - DIY Diagnosis

Got aches and pains?  Critters in the Cretaceous would have been sympathetic.  A new study reveals that painful arthritis plagued a duck-billed dinosaur.  Scientists impressively diagnosed the animal’s condition without a house call by examining its 70 million-year old bones.

The technology we use for health diagnoses are becoming so sophisticated, some people are prompted to bypass doctors and do it themselves.  Meet a man who had his genome sequenced and then had all 70 gigabytes delivered directly to him so that he could gauge his genetic health.

Also, practitioners who are trying to improve cognitive function using a battery and a few wires.   Find out the possible risks and benefits of DIY brain stimulation.

Guests:
  • Jennifer Anne - Recent graduate, University of Manchester, studies injuries and diseases in dinosaurs.
  • Carl Zimmer - Science writer, author.  National correspondent for STAT, an online magazine that reports on the frontiers of science and medicine.  His weekly column “Matter,” appears in the New York Times.
  • Peter Simpson-Young - A graduate student at the University of Sydney studying neuroscience.

AURORAS VS. TWILIGHT: A G1-class geomagnetic storm on Aug. 23-34 has sparked late summer auroras around the Arctic Circle, mixing twilight-blue with aurora-green.  It's a palette of rare beauty, which you can only see at this time of year.  Visit Spaceweather.com for photos and updates about the ongoing storm.

A SPACE WEATHER BALLOON OVER THE ANDES: Over the past three days, SpaceWeather.com and the students of Earth to Sky Calculus have launched multiple space weather balloons from sites spanning 3 countries, two continents, and more than 10,000 miles.  It's a giant radiation experiment to measure how well Earth's atmosphere protects us from cosmic rays.  A highlight so far comes from Chile, where a balloon was launched near the South Atlantic Anomaly. Radiation measurements have not yet been reduced, but photography of the space weather payload soaring more than 120,000 feet over the Andes is spectacular. 

Visit Spaceweather.com for pictures and more information about this experiment.

Big Picture Science for Monday August 15, 2016 - Are We Over the Moon?












Big Picture Science - Are We Over the Moon?

When astronaut Gene Cernan stepped off the moon in 1972, he didn’t think he’d be the last human ever to touch its surface.  But no one’s been back.  Hear astronaut Cernan’s reaction to being the last man on the moon, the reasons why President Kennedy launched the Apollo program, and why Americans haven’t returned.

Now other countries – and companies – are vying for a bigger piece of the space pie. Find out who – or what – will be visiting and even profiting.  Will the moon become an important place to make money?

Plus, the moon landing was a great step for “a man,” and “men not machines” make space history.  But what about women?  More than a dozen were qualified for space flight in the early 1960s.  Hear from one of these original “Mercury 13,” and find out why NASA grounded them.

Guests:

  • Gene Cernan – Retired American naval officer, former NASA Astronaut.
  • John Logsdon – Professor emeritus, Space Policy Institute, George Washington University
  • Al Hallonquist – Aerospace historian
  • Robert Richards – Founder and CEO of Moon Express
  • Sarah Ratley – Former pilot, member of the "Mercury 13"
  • Dan Durda – Planetary scientist, Southwest Research Institute.

Big Picture Science for Monday August 08, 2016 - Skeptic Check: After the Hereafter












ENCORE: There are few enduring truths, but one is that no one gets out of life alive. What’s less certain is what comes next. Does everything stop with death, or are we transported to another plane of existence? First-hand accounts of people who claim to have visited heaven are offered as proof of an afterlife. Now the author of one bestseller admits that his story was fabricated.

We’ll look at the genre of “heaven tourism” to see if it has anything to say about the possible existence of the hereafter, and why the idea of an afterlife seriously influences how we live our lives on Earth.

Also, a neurologist describes what is going on in the brain during near-death and other out-of-body experiences.

It’s Skeptic Check, our monthly look at critical thinking … but don’t take our word for it!

PERSEID METEOR OUTBURST: Do you love the Perseid meteor shower?  This year, you will love it even more. Forecasters say the 2016 Perseids should be twice as active as usual, filling the sky with 200+ meteors per hour on peak nights between Aug. 11th and 13th.  This is happening because Earth is heading for an unusually rich stream of debris from parent comet Swift-Tuttle.

Big Picture Science for Monday August 01, 2016 - On Defense













Big Picture Science - On Defense

The military is a dangerous calling.  But technology can help out, so researchers are constantly trying to make soldiers safer.  Writer Mary Roach investigates how scientists studying so-called human factors are protecting troops from such aggressive foes as heat, noise, and fatigue.  She also learns how bad odors were once considered a secret weapon.

And while soldiers have long used camouflage to help them blend in, insects may be the original masters of disguise.  A discovery in fossilized amber shows that a variety of bugs employed D.I.Y. camouflaging tricks 100 million years ago.

But where is the defense race headed?  The top-secret branch of the Pentagon whose job is to make tomorrow happen today has some ideas.  A reporter shares DARPA’s plan for augmented super-soldiers.

Plus, do we always need a technological boost to stay safe?  Find out how your innate chemical defense system protects you.  It’s an adrenaline rush!

Big Picture Science for Monday July 25, 2016 - Musical Universe













Big Picture Science - Musical Universe

In space, no one can hear you scream, but, using the right instruments, scientists can pick up all types of cosmic vibrations – the sort we can turn into sound.  After a decade of listening, LIGO, a billion-dollar physics experiment, has detected gravitational waves caused by the collision of massive black holes, a brief shaking of spacetime that can be translated into a short squeal. 
 
We listen to the chirp of black holes crashing into each other and wonder: could the universe contain more than individual sounds, but have actual musical structure? 
 
A theoretical physicist and jazz saxophonist updates the ancient philosophical concept of the Music of the Spheres to probe the most vexing questions confronting modern cosmology.  Find out how the evolution of the universe resembles an improvisational jazz piece, and the musical inspiration John Coltrane drew from Albert Einstein.
