CHEMISTRY: Bonded or Not?

Quantum chemistry predicts multiply bonded diuranium compounds to be stable.

Results from quantum chemical calculations that predict the existence of a series of diuranium molecules are reported. Two diuranium chlorides, U(2)Cl(6) and U(2)Cl(8)(2)(-), and three different carboxylates, U(2)(OCHO)(4), U(2)(OCHO)(6), and U(2)(OCHO)(4)Cl(2) have been studied. All species have been found to be stable with a multiply bonded U(2) unit.

A mouse is not a man is not a dog 2000 or species specificity in clinical chemistry

offer in biomedical research studies in that he or she has sufficient knowledge of human clinical biochemistry to be able to evaluate the role of species differences when an animal species is used as a surrogate for man. The development of transgenic animals has resulted in numerous models which generally resemble the background species, but in some distinct respects, appear to be the graft spe...

euthanasia: murder or not: a comparative approach.

background euthanasia is one of the most intriguing ethical, medical and law issues that marked whole xx century and beginning of the xxi century, sharply dividing scientific and unscientific public to its supporters and opponents. it also appears as one of the points where all three major religions (catholic, orthodox, and islamic) have the same view. they are strongly against legalizing mercy...
