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.

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. 

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. 

The Obama Administration released an updated draft proposal that would establish common sense safety standards 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.

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.

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. 

In the ongoing struggle between the Representative of the 21st District of Texas, Lamar Smith, and all that is holy about the peer review grant process, the battle lines are getting clearer.

 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'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.
