The production of high quality chocolate will benefit from the recent sequencing and assembly of the chocolate tree genome - Theobroma cacao - considered by chocolate experts to produce the world's finest chocolate. The Maya domesticated this variety of Theobroma cacao, 'Criollo', about 3,000 years ago in Central America and it is among the oldest domesticated tree crops, though today many growers prefer to grow hybrid cacao trees ('Trinitario') that produce chocolate of lower quality but are more resistant to disease.

The old discussion about how an airplane, that is many tons of steel, can keep staying supported in mere air, is a perfect example for how discussions way too often polarize into two camps with both sides being wrong. Little headway is possible once any attempt at resolution is portrayed as either a dangerous accommodating that leads onto a slippery slope toward defeat, or worse belonging to the other, the evil side. There are too many such issues, not only in politics or largely yet to be explored scientific fields like climatology. Even in known physics, for instance in special relativity, there are these polarized debates where both sides are wrong. The theories are well known and their domains of applicability are well delimited by both mathematics and experiment.

New findings indicate that weight gain of infants is influenced by not just formula versus breast feeding but also the type of formula the infant is consuming, which the researchers say could have implications related to the infant's risk for the development of obesity, diabetes and other diseases later in life.

Formula-fed babies gain more weight than breast-fed babies but the study set out to determine differences between formula types.   Most infant formulas are cow's milk-based and alternatives include soy-based and protein hydrolysate-based formulas. Protein hydrolysate formulas contain pre-digested proteins and typically are fed to infants who cannot tolerate the intact proteins in other formulas.
