Crystal Flowers At Micron Scale Self-Assemble In A Beaker
By simply manipulating chemical gradients in a beaker of fluid, researchers have been able to create delicate flower structures - not at the scale of inches, but microns.
These minuscule sculptures don't resemble the cubic or jagged forms normally associated with crystals, though that's what they are. Rather, fields of carnations and marigolds seem to bloom from the surface of a submerged glass slide, assembling themselves a molecule at a time.
Bach To The Blues: Are Brains Wired To Make Color-Music Connections?
Do you see music the same way as your neighbor? Apparently so. U.C. Berkeley psychologists say people in both the United States and Mexico linked the same pieces of classical orchestral music with the same colors, suggesting that humans share a common emotional palette – when it comes to music and color – that appears to be intuitive and can cross cultural barriers. They suggest that
our brains are wired to make music-color connections depending on how the melodies make us feel
Mic Stand Telescope Mount (or Camera Mount)
My wife’s cousin, the break-dancing radiologist, broke the microphone clip off my mic stand while singing karaoke on Thanksgiving (my wife and I host Thanksgiving at our house for the family every year). I had another microphone clip and replaced it so we could continue with karaoke, but I decided to keep the broken pieces of the old clip for the junk drawer.
-->What's The Weather Forecast For Uranus And Neptune? Even Worse Than Kentucky
Uranus and Neptune have a lot in common, climate-wise, even though Uranus is tipped on its side with the pole facing the sun during winter. They are both home to extreme winds blowing at speeds of over 1000 km/hour, they have hurricane-like storms as big as our whole planet and immense weather systems can last for years.
But what about their origins? Do the atmospheric patterns arise from deep down in the planet, or are they confined to shallower processes nearer the surface? Understanding the atmospheric circulation is not simple for a planet without a solid surface, where Earth-style boundaries between solid, liquid and gas layers do not exist.

Hierarchical Social Networks: Can A Math Model Of "Seepage" Clobber Terrorism?
Terror networks are comparable in their structure to hierarchical organization in companies and certain online social networks, say the authors of a paper outlining how
a mathematical model to disrupt flow of information in a complex real-world network, like a terrorist organization, can work, using minimal resources.
In those hierarchical social networks, information flows in one direction from a source, which produces the information or data, downwards to sinks, which consume it.

Journal Impact Factor Under Attack
A group contends that the journal impact factor (JIF), which ranks scholarly journals by the average number of citations their articles attract in a set period, has increasingly become an obsession in science. Impact factor of articles is used in evaluating research for funding, hiring, promotion, or institutional effectiveness.
Hofstadter's Butterfly Effect Confirmed
Hofstadter's Butterfly, a complex pattern of the energy states of electrons that resembles a butterfly, has appeared in physics textbooks as a theoretical concept of quantum mechanics for nearly 40 years but had never been directly observed - until now.

US Government Updates Draft Rule For Hydraulic Fracturing On Public And Indian Lands
Following the release of an initial draft proposal in 2012, the Department of the Interior received over 177,000 public comments that helped shape today’s updated draft proposal. The new proposal maintainssafety standards, improves integration with existing state and tribal standards and increases flexibility for oil and gas developers. The updated draft proposal will be subject to a new 30-day public comment period.

Reed Warbler, Who Be Your Daddy?
Depending on the species, males have different strategies to try and insure that they reproduce, rather than just being a step-parent.
They may try to ensure paternity by increased surveillance and fighting off the competition, they may have more frequent sex with their long-term partners, they may physically punish unfaithful females or refuse to parent potentially unrelated offspring.

The Diet Of The First New Zealanders
What was the diet and movements of the first New Zealanders like?
Isotopes from their bones and teeth can tell us. Researchers say they have been
able to identify what is likely to be the first group of people to colonize Marlborough's Wairau Bar, possibly from Polynesia around 700 years ago. They also present evidence suggesting that individuals from two other groups buried at the site had likely lived in different regions of New Zealand before being buried at Wairau Bar.
The researchers undertook isotopic analyses of samples recovered from the koiwi tangata (human remains) of the Rangitane iwi tupuna (ancestors) prior to their reburial at Wairau Bar in 2009.

Galaxy 4C+29.30 - How A Supermassive Black Hole's Gravity Can Be Tapped To Generate Immense Power
4C+29.30, a galaxy located some 850 million light years from Earth, has a new composite image which shows how the intense gravity of a supermassive black hole can be tapped to generate immense power.
This multi-wavelength view reveals that the radio emission of 4C+29.30 comes from two jets of particles that are speeding at millions of miles per hour away from a supermassive black hole at the center of the galaxy. The estimated mass of the black hole is about 100 million times the mass of our Sun. The ends of the jets show larger areas of radio emission located outside the galaxy.
There Is Scientific Consensus On Anthropogenic Climate Change Among Climate Scientists
An analysis of 4,000 abstracts of peer-reviewed articles on the topic of global warming and climate change has revealed an overwhelming consensus among climate scientists that recent warming is human-caused.

Climate Change - Emotions Run High Among College Undergraduates Taking Surveys
There's no awareness issue in climate change - almost no one on the planet hasn't heard of it or lacks an opinion.
62% of Americans believe global warming is happening - which means 38% do not. Like evolution or anti-science beliefs about genetic modification and vaccines and autism, the majority may fall along particular cultural lines but acceptance is still a problem that defies easy categorization and stereotypes. Yet framing and deficit thinking have all been tried, and they have made the problem worse. Instead of leading to more science acceptance, opinion on the climate now goes up and down with media reports about the weather.
H1N1 In Elephant Seals: First Instance In Any Marine Mammal
H1N1 originated in pigs. It emerged in humans in 2009, spreading worldwide as a pandemic. The World Health Organization now considers the H1N1 strain from 2009 to be under control, taking on the behavior of a seasonal virus.

Facial Recognition Tech Comes Of Age - $6.5 Billion By 2018
Over the past few years, demand from the surveillance market and huge spending by governments across the globe on biometric technologies has caused the facial recognition technology market to become more accurate, less costly and significantly more mainstream.
More accurate technology and the brighter economic future it can bring has led to more traction and investment from the commercial sector. The development of 3-D face recognition technology, backed by improved imaging solutions like middleware and fast analytics, has helped the technology to overcome its traditional flaws such as poor results in low lights, pose variation and image reconstruction
