When Evo Morales, Bolivia's first president of Indian origin, was appointed in 2006 he initiated a "decolonising revolution."   Now, in a new thesis in social anthropology at the University of Gothenburg, Anders Burman examines how the government policy for decolonization has been interwoven with the rituals and cosmology of the indigenous population.

For the indigenous population in the Bolivian Andes, colonialism was not something that was consigned to history when Bolivia was founded. Their exploitation and marginalization simply took on new forms. 

Mendel solved the logic of inheritance in his monastery garden with no more technology than Darwin had in his garden at Down House, so why couldn't Darwin have done it too? A Journal of Biology article argues that Darwin's background, influences and research focus gave him a viewpoint that prevented him from interpreting the evidence that was all around him, even in his own work. 

Moravian priest and scientist Gregor Mendel (1822 - 1884) studied clear-cut, inherited traits in pea plants, which he grew in the monastery gardens in Brno. Mendel showed that trait inheritance follows simple laws, and 'Mendels Laws Of Inheritance' (1) were later named after him. Mendel's work was rediscovered at the beginning of the 20th century, and laid the foundations for genetics.

In times of starvation, cells tighten their belts: they start to digest their own proteins and cellular organs. The process - known as autophagy - takes place in special organelles called autophagosomes. It is a strategy that simple yeast cells have developed as a means of survival when times get tough, and in the course of evolution, it has become a kind of self-cleaning process. In mammalian cells, autophagosomes are also responsible for getting rid of misfolded proteins, damaged organelles or disease-causing bacteria. 

What had once been impossible has now been shown to be possible – an alloy between two incompatible elements.

A research team led by Professor H.K. Mao from Carnegie Institution of Washington and Professor Rajeev Ahuja from UU have used high pressure experiments and theoretical calculations to study the behavior of Ce3Al under high pressure.

"We were surprised to find that Cerium and Aluminium formed a so called substitutional alloy under high pressure. Forming these alloys has been limited to elements close in atomic radii and electronegativity up until now", sais Professor Rajeev Ahuja of Uppsala University.

You may know of people who ridicule lottery players because the odds are so great and, it would seem, they can't do simple math.    But most people don't ridicule stock market investors even though the same circumstances - a lack of real knowledge and a field of competitors doing the same thing - make it less likely they will be successful unless fortune makes their decisions align with people who know what they are doing.

The riskier investors tend to act, the more socioeconomic characteristics they share with people who play state lotteries and,  just like the lottery, returns on average are lower for those who invest this way in the stock market, research from The University of Texas at Austin shows.
 

A system of opposing genetic forces determines why mammals develop a single row of teeth, while sharks sport several, according to a study published today in the journal Science. When completely understood, the genetic program described in the study may help guide efforts to re-grow missing teeth and prevent cleft palate, one of the most common birth defects.
