Convergent Evolution: Raising a Family from the Dead
New molecular evidence shows that Hawaiian honeyeaters did not evolve from the similar looking Australasian honeyeaters, but instead represent a striking case of convergent evolution. These now extinct birds form their own family, representing the only complete extinction of an entire avian family in modern times.

It is often caused by bacteria, but can also be caused and complicated by fungus. We report a case of bacterial necrotizing fasciitis that was complicated by a fatal fungal infection, a rare clinical presentation affecting the upper limbs, head and neck, in a you...
متن کاملComparative Study on the Ni2+ Biosorption Capacity and Properties of Living and Dead Pseudomonas putida Cells
Microbial cells have been successfully used as biosorbents to remove heavy metals from wastewater. In some cases, dead cells appear to offer more advantages than living cells in the removal and recovery of heavy metal ions from industrial wastewater. Maintaining higher biosorption capability and understanding t...
متن کاملRaising the Dead: Clues to Type Ia Supernova Physics from the Remnant 0509−67.5
We present Chandra X-ray observations of the young supernova remnant (SNR) 0509−67.5 in the Large Magellanic Cloud (LMC), believed to be the product of a Type Ia supernova (SN Ia). The remnant is very round in shape, with a distinct clumpy shell-like structure that extends to an average radius of 14.8 ′′ (3.6 pc) in the X-ray band. Our Chandra data reveal the remnant to be rich in silicon, sulf...
متن کاملThe Sorption of Bacteriophage by Living and Dead Susceptible Bacteria
The above data relating to the antistaphylococcus phage and single strain of S. aureus with which previous papers have been concerned (9, 10, 11, 12), bring out the following points. (a) For live, resting, susceptible B suspended in broth as well as for B in a P-B mixture during the logarithmic phases of B growth and P formation, P is distributed in a manner typical of numerous materials solubl...
