A little more than a year after University of Wisconsin-Madison scientists showed they could turn skin cells back into stem cells, they have pulsating proof that these "induced" stem cells can indeed form the specialized cells that make up heart muscle. 

In a study published  in Circulation Research, the team showed that they were able to grow working heart-muscle cells (cardiomyocytes) from induced pluripotent stem cells, known as iPS cells. 

The heart cells were originally reprogrammed from human skin cells by James Thomson and Junying Yu, two of Kamp's co-authors on the study. 

In all the hype surrounding the Large Hadron Collider during the last few years, it was easy to miss the fact that low energy physics was still accomplishing a lot - and that no one was sure what the LHC could really do because we didn't know what needed discovering.
 
What we think it will do  is based on the success of the indirect approach in science.   Darwin's evolution by natural selection, for example, gained early acceptance because without it nothing much in biology made sense.  Later discoveries including genetics and a detailed fossil record reaffirmed that what makes the most sense can often be true.  

I recently spoke to biological anthropologist Dr. Helen Fisher about her groundbreaking work on the chemical basis of our personality and its influence on who we fall in love with.  As it turns out, science can shed a lot of light on a topic previously dominated by doubt, horoscopes, and what our mama told us.

 “So have you read the book?” asked Fisher.  “What ‘type’ are you?” 

 “Explorer/Negotiator.  Are you sizing me up according to my ‘type’ now?” I teased.

The Brits are always thinking ahead and we could learn a thing or two from them on this side of the pond.   Those cheeky blokes are ditching pricey baubles in favor of if-we-keep-printing-money-we-will-be-Zimbabwe type ways of romancing loved ones this Valentine's Day - that is to say, without throwing out a lot of dough.    

Research from a voice-to-text company over there called SpinVox claims almost two thirds of men (65%) have made huge cuts in spending this Valentines day.   1.6 million even claim they are following in the footsteps of Byron, Keats, and Shakespeare; not just by being poor, struggling lotharios getting by on charm but also by penning their own love poems this February 14th.

I am a firm believer in the possibility and promise of embryonic stem cells. In a politically, religiously and even scientifically charged climate, this is a risky thing to announce. But as a journalist, I must divorce myself from my own personal opinions and biases and present the facts.  That being said, it is still satisfying writing upon a topic that you believe in. This was the case when I wrote an article about Geron Pharmaceuticals recently launched human clinical trials using embryonic stem cell research to repair spinal cord damage.

Today, of all days, anything is possible. The laws of man and god are subverted by that of Murphy. This day is made doubly potent by its placement before the geek's darkest day of the year: Valentine's Day. And during this day on which anything that can go wrong will go wrong, it seems that even the cold truth of mathematics itself has failed. Specifically, two equals one. Damn. You shoulda been more consistent with the salt, garlic and Haitian door totems.

A York University research team has tracked the migration of songbirds,  the most common type of bird in our skies, by outfitting them with tiny geolocator backpacks – a world first and interesting because they are too small for conventional satellite tracking.    They now say we have underestimated the flight performance of songbirds dramatically.

Adaptation is one of the driving forces behind evolution, along with selection and the appearance of new species, say a group of Ludwig-Maximilians-Universität München researchers, but they say that the interpretation familiar since Darwin - these processes increase the "fitness" of the species overall, since, of two competing species, only the fittest would survive - is actually a case of the fittest being the 'weakest'  most often.

University of Leicester biologist Dr David Harper has conducted research for over 25 years at Lake Naivasha in Kenya and says today that your cheap boyfriend's (unless you are are the cheap boyfriend, in which case he means you) cut-price Valentine roses which are exported for sale to the UK are 'bleeding that country dry.'

Harper claimed that cheap roses grown by companies that had no concern for the environment were having a devastating effect on the ecology of Lake Naivasha - the center of Kenya's horticultural industry.  Instead, he urged UK shoppers to buy Fair Trade roses produced by companies that  he says are environmentally conscientious and had a transparent supply chain.

Are you smarter than a pigeon?   We don't mean smarter as in able to figure out why it's $14  a day for lousy internet access in a hotel or $14 to see an old movie in your hotel room or the hospitality industry's general preference for the number 14, we mean practical social smarts, like meeting the opposite sex.    Animals have "social smarts" too, it turns out, with a range of behaviors that can enhance species survival, according to studies being presented here in Chicago at the American Association for the Advancement of Science (AAAS) annual meeting. 

Evolution shouldn't leave out social behavior, it seems.
