At their best, leaders get something from their workforce that would have been impossible otherwise. Research on this 'transformational leadership' style suggests that it can inspire employees to more creative performance - such as coming up with new and useful products – as well as encouraging helping behaviours. However, these benefits aren't seen across every study. A new paper suggests one reason is that some people simply don't need what the transformational leader has to offer.Phillip Gi........

If only rhinos were as plentiful in the wild as they are in today's media landscape.
Since this summer, news of the western black rhino's extinction has been continuously breaking on popular sites and timelines. Although the last of its kind was seen in 2001 and the species was declared extinct in 2011 — as detailed in this sharp SA piece — a realization of the loss has been lately making the rounds with renewed despair....

Despite the research telling us people will like you more if you are warm and hire you more when you are competent–perhaps, it is more important that you are moral. While that may seem odd at first, it actually makes some sense. A seemingly warm and friendly person may be hiding nefarious motives under that […]
Is that quick decision a good indicator of your moral character?

I've taken my time in posting this entry specifically dedicated to the paper by Virginia Chaidez and colleagues* which "puts to rest the idea that gastrointestinal problems among children with autism spectrum disorder are just an accumulation of case reports" according to one of the paper authors (see here). It's not that I don't see these findings to be absolutely fascinating, but rather that I wanted the research dust to settle a little before I added my [inflation adjusted] 10 ........ Read more »

I remember, aged five or so, a friend and I were the cool police motorcyclists from the TV show CHiPs. Our props were limited to the usual paraphernalia of a suburban home and yet somehow both of us knew when the other person was on foot or on his Kawasaki motorbike, which routes through the house were motorways, where the baddies were located, and most important, we both understood the plot of our game.For a new study, a team of psychologists in Australia has taken an interest in the conversati........

Scientists have theoretically found previously unknown layers on stars that enhance the mystery of the mechanism through which neutron stars heat up.
In astronomy, neutron star is a star composed of neutrons. It is a celestial body consisting entirely of a very dense compact mass of neutrons, the remnant of a star that has collapsed under its own gravity.
It is a neutral elementary particle. Technical........ Read more »

Does emotional intelligence, a set of abilities concerned with processing emotions and emotional information, contribute to how one member of a self-managed group who lacks formal authority may influence other members?

This week a widely-criticised paper claiming negative effects of Roundup and Roundup-tolerant genetically modified maize on rats was retracted by the journal Food and Chemical Toxicology. The author, Professor Seralini, stands by the results, but received a letter from the journal stating that “The panel had many concerns about the quality of the data, and ultimately recommended that the article should be withdrawn.”
Criticisms included inadequate numbers of rats to draw conclusions........ Read more »

CD133 and phage single–chain antibody fragment (scFv) targeting CD133:
The prominins are an emerging family of novel proteins and one of the first identified members of this family is CD133, which is a penta-transmembrane glycoprotein. CD133 is found to be a marker of cancer stem cells (CSCs) in a number of tumors making them one of the strong candidates for future cancer therapy. You can work on functions and specific ligands of this family of proteins as these need a lot of research.[........ Read more »

Scientists have presented a new way to study Bose-Einstein condensates (BECs) that are the coldest objects in the Universe by canceling the damage caused by light.

Bose-Einstein condensates (BECs):
BECs are considered as the coldest objects in the universe as they are very close to absolute zero, i.e. very near 0 K or −273.15 °C. They consist of few clusters of atoms. At such temperature, atoms behave as ........ Read more »

The Stanford Prison Experiment has had a remarkable influence in psychology, and has been used to demonstrate the alleged power of situations to triumph over individual differences.
