A new analysis used Alaska Department of Fish and Game data and fish estimates from 2007 to 2016 to quantify the number and value of Pacific salmon harvested from streams, rivers, and lakes in Alaska. They estimate that it's 48,000,000 fish per year, and that is without  the recreational fishing catch and local communities where it's a food staple. The value is $88,000,000 per year.

While $88 million is a fine industry it speaks poorly about those who protest farming and hunting while claiming to care about nature. Good luck going to a fancy restaurant without having a server note that the salmon you might order was wild.

Do you listen to experts when it comes to food? If so, you are in the rarity. Most mimic what their friends do, according to recent survey results.

Study participants ate an extra fifth of a portion of fruit and vegetables for every portion they thought their social media peers ate - and they consumed an extra portion of snack foods and sugary drinks for every three portions they believed their online social circles did.

So our friends determine our eating behavior? Or do we tend to be friends with people who have our lifestyles? And what might that mean for government panels that want to nudge the behavior of the public? Will we see targeted ad campaigns at key social media users?

An experiment before the 2016 Trump-Clinton debate in metropolitan New York City showed that it was possible to have people be less polarized. 

They showed questionnaire responses where respondents were actually more moderate than their real responses, and then people justified their moderation.

Posing as political researchers, a research team from McGill and Lund Universities approached 136 voters at the first Donald Trump and Hilary Clinton presidential debate, on Long Island, and asked them to compare Trump and Clinton on various leadership traits (such as courage, vision, and analytic skills) by putting an X on a sliding scale. 

Have you ever used a public charging station to charge your mobile phone when it runs out of battery? If so, watch out for “juice jacking”.

Cybercriminals are on the prowl to infect your mobile devices such as smartphones and tablet computers and access your personal data, or install malware while you charge them.

Specifically, juice jacking is a cyber attack in which criminals use publicly accessible USB charging ports or cables to install malicious software on your mobile device and/or steal personal data from it.

NGC 4490, nicknamed the "Cocoon Galaxy" because of its shape, has "a clear double nucleus structure," according to a new paper.

It's only realized now because while one nucleus can be seen in optical wavelengths, the other is hidden in dust and can only be seen in infrared and radio wavelengths.

The work started when first author Allen Lawrence was taking undergraduate astronomy classes at the University of Wisconsin-Madison. He had the chance to study one of two galaxy systems and picked NGC 4490, which is interacting with a smaller galaxy, NGC 4485. The system is about 20 percent of the size of the Milky Way, located in the Northern Hemisphere and about 30 million light years from Earth.

Intelligence Squared recently had a debate on nuclear energy kicked off by Bill Nye, the famous Science Guy, and moderated by John Donvan.

On the pro-nuclear side were Daniel Poneman, Deputy Secretary of Energy under President Obama, and Kirsty Gogan, co-founder of Energy for Humanity, while on the anti-science side was Gregory Jaczko, Obama's chairman of the US Nuclear Regulatory Commission(NRC), and Arjun Makhijani, President of the Institute for Energy and Environmental Research.(1)

What was missing? An actual nuclear physicist.

Would you have a debate on vaccine safety without a doctor? A debate on climate change without a climate scientist? When it comes to nuclear energy, everyone is such an expert actual expertise seems to be irrelevant. 

It doesn't seem like it if you watch political news but humans are unusually cooperative. We are unique in that we often cooperate with genetically unrelated strangers.

Nurses, firefighters, helping someone who dropped a package, standing in line, there is no natural selection benefit to that. In a natural selection-dominated world, the cheats, nepotists, and cronies would always win but unlike most of the animal kingdom, those behaviors are considered deviant.

Why do we cooperate? Language, intelligence, religion, the desire to hunt large game, there is no shortage of speculation about why we became Apex Cooperators. 

Everyone has heard of the nutrient, nitrogen, but why is it important to plants?

Despite flying being the single fastest way to grow our individual carbon footprint, people still want to fly. Passenger numbers even grew by 3.3% globally last year alone. The hype around “Flygskam” – a global movement championed by climate activist Greta Thunberg that encourages people to stop traveling by plane – seems to have attracted more media attention than actual followers.

If you have never heard of the Journal of International Psychology, you are not alone.
