The long, low dune

Cosmic Diary by Lori Fenton - January 05, 2015

A piece of Mars: A long, low dune covered in long, linear ripples stretches across the scene (600×450 m; 1969×1476 ft). Dark gray areas on the dune show where sand has most recently moved. A small slip face has formed on the southeast side of the dune, but ripples have formed on it, so there haven’t been any recent avalanches here. (ESP_038615_1665, NASA/JPL/Univ. of Arizona)

Meet Your Replacements

ENCORE There’s no one like you. At least, not yet. But in some visions of the future, androids can do just about everything, computers will hook directly into your brain, and genetic human-hybrids with exotic traits will be walking the streets. So could humans become an endangered species?

Be prepared to meet the new-and-improved you. But how much human would actually remain in the humanoids of the future?

Plus, tips for preventing our own extinction in the face of inevitable natural catastrophes.

Skeptic Check: Got a Sweet Truth?

Big Picture Science Latest Shows - December 29, 2014

ENCORE  The sweet stuff is getting sour press. Some researchers say sugar is toxic. A new study seems to support that idea: mice fed the human equivalent of an extra three sodas a day become infertile or die. But should cupcakes be regulated like alcohol?

Hear both sides of the debate. Another researcher says that animal studies are misleading, and that, for good health, you should count calories, not candy and carbs.

Plus, an investigative reporter exposes the tricks that giant food companies employ to keep you hooked on sugar, salt, and fat.

It’s Skeptic Check … but don’t take our word for it!

Science Fiction True

Big Picture Science Latest Shows - December 22, 2014

Don’t believe everything you see on TV or the movies. Science fiction is just a guide to how our future might unfold. It can be misleading, as anyone who yearns for a flying car can tell you. And yet, sometimes fantasy becomes fact. Think of the prototype cellphones in Star Trek

We take a look at science that seems inspired by filmic sci-fi, for example scientists manipulating memory as in Sunshine of the Spotless Mind. And despite his famous film meltdown, Charleton Heston hasn’t stopped the Soylent company from producing what it calls the food of the future.

Plus, why eco-disaster films have the science wrong, but not in the way you might think. And, what if our brains are simply wired to accept film as fact?

Wind, wind, impact(!), and then more wind…

Cosmic Diary by Lori Fenton - December 19, 2014

A piece of Mars: Some time ago, something hit the ground on Mars and made this impact crater, right into a field of ripples. Stuff thrown up during the impact fell back down, burying the ripples with the gray ejecta rays that radiate from the crater. But the wind kept blowing, and in some places you can see where new ripples have formed on top of the ejecta. That’s Mars for you: wind, wind, wind, impact(!), more wind… (HiRISE ESP_038918_1650, NASA/JPL/Univ. of Arizona)

AGU Fall Meeting 2014: Solar System Small Bodies: Relics of Formation and New Worlds to Explore

Cosmic Diary Marchis - December 18, 2014

Can you believe it is December already!? As usual, it is a busy month with the AGU Fall Conference.  I co-organized a session on small solar system bodies with Padma Yanamandra-Fisher (PSI)  and Julie Castillo (JPL).  We will talk about recent discoveries in this emerging field including the discovery of rings around Chariklo, the understanding of regolith motion on asteroids, the new lander for Hayabusa 2 (MASCOT) and off course adaptive optics observations of asteroids. Below more info. See you there!

Where: Thursday, December 18, 2014 01:40 PM – 03:40 PM
When: Moscone West 3002

Why: The composition and physical properties of Small Solar System Bodies (SSSBs), remnants of the formation of planets, are key to better understand the origins of our solar system and their potential as resources is necessary for robotic and human exploration. Missions such as ESA/Gaia, NASA/OSIRIS-REx, JAXA/Hyabusa-2, NASA/Dawn and NASA/New Horizons, to study asteroids, comets, dwarf planets and TNOs are poised to provide new in situ information. on SSSBs.  Recent remote observations of bright and main belt comets; asteroid Chariklo, with its ring system; asteroid and KBO binaries illustrate that the distinction between comets and asteroids is blurred, providing a new paradigm for such classification. This session welcomes abstracts on the remarkable results bringing information on the internal structure and composition of SSSBs based on space and ground-based data, numerical models, as well as instrument/mission concepts in theprospect of future exploration.

Artistic representation of the triple asteroid system showing the large 270-km asteroid Sylvia surrounded by its two satellites, Romulus and Remus. The differentiated interior of the asteroid is shown through a cutaway diagram. The primary asteroid of the system may have a dense, regularly-shaped core, surrounding by a fluffy or fractured material. The two moons are shown to be strongly elongated, and composed of two lobes, as suggested by the recently observed occultation data by the satellite Romulus. (credits: D. Futselaar & F. Marchis)

Shocking Ideas

Big Picture Science Latest Shows - December 15, 2014

Electricity is so 19th century. Most of the uses for it were established by the 1920s. So there’s nothing innovative left to do, right? That’s not the opinion of the Nobel committee that awarded its 2014 physics prize to scientists who invented the blue LED.

Find out why this LED hue of blue was worthy of our most prestigious science prize … how some bacteria actually breathe rust … and a plan to cure disease by zapping our nervous system with electric pulses.

Aeolian shoreline

Cosmic Diary by Lori Fenton - December 08, 2014

A piece of Mars: On the left is a steep slope leading to a hill. On the right are waves – but not waves of water or any other kind of liquid. These are dunes or very large ripples, blown by the wind into intricate patterns. Sharp eyes might spy boulders that have rolled downslope into this “sea” – there’s even a dotted track that one boulder made as it went. Can you find the boulder? (HiRISE ESP_038799_1590, NASA/JPL/Univ. of Arizona)

Living Computers

Big Picture Science Latest Shows - December 08, 2014

It’s the most dramatic technical development of recent times: Teams of people working for decades to produce a slow-motion revolution we call computing. As these devices become increasingly powerful, we recall that a pioneer from the nineteenth century – Ada Lovelace, a mathematician and Lord Byron’s daughter – said they would never surpass human ability. Was she right?

We consider the near-term future of computing as the Internet of Things is poised to link everything together, and biologists adopt the techniques of information science to program living cells.
