Big Picture Science for Oct 01, 2018 - Wonder Women












Big Picture Science - Wonder Women

(Repeat) We’re hearing about harassment of, and barriers to, women seeking careers in politics and entertainment. But what about science? Science is supposed to be uniquely merit-based and objective. And yet the data say otherwise. A new study reveals widespread harassment of women of color in space science.

We look at the role that a hostile work environment plays in keeping women from pursuing scientific careers. While more women than ever are holding jobs in science, the percentage in tech and computer science has flattened out or even dropped.  A memo from a software engineer at an Internet giant claims it’s because female brains aren’t suited for tech. Find out what the science says.

Plus, women staring down discrimination. One woman’s reaction to her guidance counselor’s suggestion that she skip calculus and have babies. And SACNAS, the organization changing the face of science for Latina and Native American women.

Big Picture Science for Sep 24, 2018 - Skeptic Check: Heal Thyself












Big Picture Science - Skeptic Check: Heal Thyself

Do we still need doctors?  There are umpteen alternative sources of medical advice, including endless and heartfelt health tips from people without medical degrees. Frankly, self-diagnosis with a health app is easier and cheaper than a trip to a clinic.   Since we’re urged to be our own health advocate and seek second opinions, why not ask Alexa or consult with a celebrity about what ails us?

Find out if you can trust these alternative medical advice platforms.  Plus, lessons from an AIDS fighter about ignoring the findings of medical science.

And, if AI can diagnose better than an MD, will we stop listening to doctors altogether?

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

Big Picture Science for Sep 17, 2018 - DNA: Nature's Hard Drive












Big Picture Science - DNA: Nature's Hard Drive

The biotech tool CRISPR lets us do more than shuffle genes.  Researchers have embedded an animated GIF into a living organism’s DNA, proving that the molecule is a great repository for information.  This has encouraged speculation that DNA could be used by aliens to send messages.

Meanwhile, nature has seized on this powerful storage system in surprising ways.  Scientists have learned that the 98% of our genome – once dismissed as “junk” – contains valuable genetic treasure. Find out what project ENCODE is learning about the “dark genome.”

Plus, how viruses became the original stealth coders, inserting their DNA into ancient bacteria and eventually leading to the development of CRISPR technology.  Discover the potential of this powerful tool, from curing disease to making pig organs transplant-friendly, and the possible dark side of quick-and-easy gene editing.

Big Picture Science for Sep 10, 2018 - Angles of a Hack












Big Picture Science - Angles of a Hack

(Repeat)
  Changed your computer password recently?  We all try to stay one step ahead of the hackers, but the fear factor is increasing.  The risks can range from stolen social security numbers to sabotaging a national power grid.

Sixty years ago, when hacking meant nosing around the telephone network, it seemed innocent enough.  And not all modern hacking has criminal intent.  Today, there are biohackers who experiment with implanted electronic devices to improve themselves, and geoengineers who propose to hack the climate.  But in our efforts to cool an overheated planet, might we be going down a dangerous path?

In this second of two episodes on hacking, the modern variations of “hacking,” and their consequences. Plus: when does hacking a system improve it?

Big Picture Science for Sep 03, 2018 - Plan of a Hack












Big Picture Science - Plan of a Hack

(Repeat)  Long before cyber criminals were stealing ATM passwords, phone phreaks were tapping into the telephone system. Their motivation was not monetary, but the thrill of defeating a complex, invisible network. Today “hacking” can apply to cyberwarfare, biological tinkering, or even geoengineering. Often it has negative connotations, but the original definition of “hacking” was something else.

In this first of two episodes on hacking, we look at the original practitioners – the teenagers and mavericks who hacked Ma Bell for thrills - and the difference between hacking for fun and for profit.
