12:50 AM | Submit Predictions to Fly in an Asteroid Time Capsule
You have four weeks left (until September 30, 2014) to submit names to send to an asteroid, and now you can also separately submit space exploration predictions or images to send in a time capsule to and from that same asteroid. Both sets of information will fly etched on microchips on board the NASA OSIRIS-REx spacecraft.

8:41 PM | Removing both breasts may not boost cancer survival
Women diagnosed with cancer in one breast who choose to have both breasts removed may not have better survival rates than women who opt for breast-conserving surgery and radiation.

8:00 PM | Young Children can Benefit from Multi-Vitamin-Mineral Supplementation
Scientific progress is much slower than news the news cycle. So it is surprising when scientific studies create a media frenzy. After all, assembling the totality of the evidence isn’t  a matter of immediacy. The creation of regulations is even slower. Last January, Madden, DeBias & Cook published a market analysis of vitamin supplements in JAMA Pediatrics.

7:12 PM | My Son's First Day: 10 Things I Want My Child To Gain From Schooling
Getting a great education is not about smartness. I picked the brown, leather high tops with the fluorescent green laces. Shoes make an impression on the first day of school. My son, Robeson, picked a Cars inspired backpack and a Planes lunchbox - school shopping. The small traditions that comprise the first-day build-up almost brought me to tears (not because of the prices). Parents’ expectations of their children’s schooling surface consciously or unconsciously. It’s only […]

6:00 PM | Biography of our ingenious species is full of twists
Humans innovate to dodge disaster, and we are pretty good at it, according to The Big Ratchet by Ruth DeFries – but can we do it indefinitely?

5:12 PM | How ocean dust makes rain clouds When storm clouds form over the...
How ocean dust makes rain clouds When storm clouds form over the ocean they’re drawing that moisture into the atmosphere to form clouds.  At that point it takes many water vapor molecules to freeze and bond with one another to fall from the sky, but how does this bonding process start?   It begins with tiny particles of organic matter such as parts of cells of dead organisms that the water vapor can bond to (as ice). Scientists at UC San Diego now theorize that these particles […]

2:54 PM | Terremoto in Emilia: colpa di due scosse ravvicinate
Non è solo questione di magnitudo: due scosse di terremoto moderate ma consecutive possono infatti essere più devastanti di un singolo evento sismico di maggiore intensità. È quanto evidenziato da uno studio italiano, pubblicato su Seismological Research Letters, condotto da un gruppo di ricercatori dell’Osservatorio Vesuviano dell’Istituto Nazionale di Geofisica e Vulcanologia (Ingv) di Napoli. Gli scienziati hanno utilizzato le onde sismiche registrate […]

1:35 PM | Switching to copper catalysts makes solar cells cheaper
The chemical stew that makes it possible is a mix of copper nitrate, phosphorous acid, hydrogen fluoride and water. When applied to a silicon wafer, the phosphorus acid reduces the copper ions to copper nanoparticles.

1:05 PM | Accounting for biological aggregation in heating and imaging of magnetic nanoparticles
Biological aggregation is a critical, yet often overlooked factor in the medical application of nanoparticles. Here scientists systematically characterize the effects of aggregation on both radiofrequency heating and magnetic resonance image (MRI) contrast of magnetic iron oxide nanoparticles, including detailed analysis of the aggregate morphologies based on quasi-fractal descriptions.

12:57 PM | Single laser stops molecular tumbling motion instantly
In the quantum world, making the simple atom behave is one thing, but making the more complex molecule behave is another story. Now scientists have figured out an elegant way to stop a molecule from tumbling so that its potential for new applications, such as quantum computing, can be harnessed: shine a single laser on a trapped molecule and it instantly cools to the temperature of outer space, stopping the rotation of the molecule.

Running the Payette River… (all photos by author). “Get set to get wet” should’ve been our mantra over the past week, as we journeyed north of Boise into the Idaho panhandle. Of course, we always thought of the northern stem of the state as more of a chimney, but hey, if you think of a [...]
