A new study in Proceedings of the Royal Society B says it is the first to demonstrate that birds possess empathy - and they say they have verified it using both behavioral and physiological methods to measure these traits.

Using non-invasive physiological monitoring, the researchers say domestic hens show a clear physiological and behavioral response to their chicks' distress.   During one of the controlled experiments, when the baby chicks were exposed to a puff of air, the hens' heart rate increased and eye temperature decreased. The hens also changed their behavior and reacted with increased alertness, decreased preening and increased vocalizations directed to their chicks.

The Greenland and Antarctic ice sheets are losing mass at an accelerating pace, according to a new study in Geophysical Research Letters. The authors suggest these ice sheets are overtaking ice loss from Earth's mountain glaciers and ice caps to become the dominant contributor to global sea level rise.

You've seen it everywhere by now - Earth's sixth mass extinction: Is it almost here? and other articles discussing an article in Nature (471, 51–57 doi:10.1038/nature09678) claiming the end of the world is nigh.  

Hey, I like to live in important times.  So do most people.  And something so important it has only happened 5 times in 540 million years, well that is really special.    But is it real? 

Arctic Ice March 2011 - Update #1

Edited March 11 2011 - content added below ice prediction chart to address points raised in readers' comments.

The Arctic sea ice extent has grown a little recently.  Ice extent as of  March 10 2011 is  13749688 km² (as reported by IJIS).  Ice extent commonly grows until the end of March.  But any ice which forms now will still be very young, thin, salty ice when the temperatures begin to rise - not forgetting that temperatures are already anomalously high over much of the Arctic.

If you want to win the NCAA College Basketball Tournament office pool and know nothing about basketball, the good news is you have just as much chance as devoted college basketball fans unless you get all crazy about it.   

One solution is to try and play it safe by picking all the top seeds in the brackets to make it to the Final Four and then using a back-azimuth strategy to determine the winners among the early games.   But upsets are almost a guarantee in the NCAA Tournament.   So what is the optimum strategy for people without a clue?

José Marian, the author of this paper about sperm injection, very kindly and promptly provided me with a copy. I began reading with an enthusiasm which only increased as I proceeded through the article. It's short, clear, and tantalizing.

Mendeley, which bills itself as the world's largest crowd-sourced research database, today announced the Mendeley API Binary Battle, challenging developers to build an application on top of Mendeley's open database of over 70 million research papers, usage statistics, reader demographics, social tags, and related research recommendations.

The prize?  $10,001. 

Modeled after Last.fm, Mendeley seeks to use its social reference manager and collaboration platform to make research more productive and transparent. This challenge is all about creating applications that open up its academic data to others. 

Some researchers have wondered why a few credibility issues in particular studies (see Marc Hauser in psychology and parts of the IPCC report in 2007 and anything at all related to cold fusion in physics) would damage the image of researchers across an entire discipline.  It's plain old psychology.

Despite what some sociologists want you to believe, it isn't always men doing the objectification of women.  At least on Facebook, some women go out of their way to be noticed.

The millenia-old contention that women care more about their appearance and use it in competition is still alive in the digital age.   A new study published in Cyberpsychology, Behavior and Social Networking contends that females who base their self worth on their appearance tend to share more photos online and maintain larger networks on online social networking sites. 

While wireless Internet has been wonderful, true wireless devices - with no need for batteries - are the real revolution needed in technology to make a more positive environmental scenario for the future.   

We're getting closer.  A doctoral student at Rensselaer Polytechnic Institute has demonstrated a new system that uses ultrasound to simultaneously transmit large quantities of data and power wirelessly, even through thick metal walls like the hulls of ships and submarines.
