A couple of weeks ago ago, a debate about the existence of scavenging cephalopods broke out on the cephalopod mailing list. A few days later, such a creature appeared in the news as if conjured!

A grad student had e-mailed the ceph-list because he’d found a website that claimed “most cephalopods are active hunters while some are scavengers.” He couldn’t think of any scavenging cephalopods, and wanted to know if anyone else could.

The Greenland ice sheet has a tale to tell about ancient greenhouse gas emissions too. Researchers have determined how much methane originates from natural sources and how much is due to human activity, from Roman times to the present.

Methane is an underestimated greenhouse gas, 23X the impact of CO2 but not as long-lived, and like CO2 it has natural sources and also originates from human activities. The emissions from natural sources varies due to \climate variations; as an example, bacteria in wetlands release methane and less is emitted in dry cycles when wetlands shrink. 

Thinking of some amazing organisms in a sandy beach, the sand bubbler crab always comes in mind. Dotilla clepsydrodactylus, the sand bubbler crab, is the one crab which makes the beaches more beautiful by displaying its marvelous art. 

While walking on beaches in Andaman Islands, India, during low tide we can savor the beautiful designs done by these crabs. So, why and how these crabs design like this? The answer is: food!! These crabs have no idea that they are making beautiful designs for us. They are so ignorant that they design pretty well!

A 45-year meta-analysis of 240 science studies found that 'organic' processed food is the same in pesticides, the same in nutrition and a whole lot more expensive.

"...there isn’t much difference between organic and conventional foods, if you’re an adult and making a decision based solely on your health,” said Dena Bravata, senior author of the paper and a physician at Stanford’s Center for Health Policy.

The Affordable Care Act controversy rages on. In this week's BMJ, journalist Jeanne Lenzer says the basic assumption that US people don't have enough health care is misleading and in reality, Americans have too much - and that unnecessary care costs an estimated $800 billion per year. 

The article arrives as an international conference named 'Preventing Overdiagnosis' was announced for September, 2013 in the United States, hosted by The Dartmouth Institute for Health Policy and Clinical Practice, in partnership with the BMJ, Consumer Reports and Bond University of Australia.

Researchers have found a way to 'toggle' the intestinal enzymes responsible for processing starchy foods on and off, which could lead to better control of those processes in people with Type 2 diabetes.

This "toggling" was discovered in the lab of  Simon Fraser University chemist Mario Pinto, who has designed inhibitors capable of regulating each of the four starch-digesting enzymes known as alpha-glucosidases. Three of those enzymes are responsible for generating glucose from starch, each in different ways. A fourth enzyme breaks down sucrose, also giving glucose. Occasionally one or more of the enzymes is missing, which also affects how glucose is created, Pinto explains.

While rabid Democrats charge Republicans with racism and rabid Republicans do the same to Democrats, the least partisan people and therefore most independent are really the most likely to use race as a criterion, according to a new survey.  While a Republican candidate outraged the opposition by stating 47% were going to vote Democrat no matter what, voting history shows that is largely true on both sides.  That 6% of swing voters might be a problem for President Obama, if the survey results are accurate.

Does clean air have a cost where it makes sense versus where it doesn't? What about human life in general?  

Economists still try to create a metric and a group from the University of Chicago and MIT tackled the financial results of extensive environmental regulations, which have brought cleaner air and health improvements to the United States but also increased the cost of manufacturing and led to reduced industrial productivity along with outsourcing jobs. 

Biologists of the coming decade are going to need to know a whole lot of physics, math and statistics. Everyone is going to need to do more math, really. The days when it was just a language science used here and there is long gone.

There is a common belief that men are empowered sexually. Men know this is silly, of course. It is women who decide each day if they want to have sex or not, not men.  It's in college that young men learn this lesson.
