    " Jeremy Luterbacher von der University of Wisconsin-Madison und seine Kollegen berichten nun allerdings von einem neuen Verfahren, das Zellulose offenbar besser knacken kann als alle bisherigen. Der Schlüsselfaktor dabei ist eine Substanz namens Gamma-Valerolacton (GVL). Es handelt sich um einen Wirkstoff, der sich wiederum selbst aus Pflanzengewebe gewinnen lässt - also erneuerbar ist. Er kann Zellulose aus Pflanzenmaterial von Ernterückständen oder sogar aus Holz zu Zucker abbauen"

    A study published Sept. 29 by Luis Populin, a professor of anatomy at the University of Wisconsin-Madison, shows that under specific conditions, a rhesus macaque monkey that normally would fail the "mark test" can still recognize itself in the mirror and perform actions that scientists would expect from animals that are self-aware.

    David Baum, University of Wisconsin, says: "All agree that eukaryotes arose from a symbiotic relationship between two cell types: bacteria that became mitochondria and a host cell, archaea, or a close relative of archaea, that became the cytoplasm and nucleus. This symbiosis explains the origin of mitochondria, but what about other eukaryotic structures, most notably the nucleus?" The Baums' inside-out theory provides a gradual path by which eukaryotic cells could have evolved. The first stage began with a bacterial cell whose outer membrane forms protrusions, which the Baums call 'blebs', that reached out from the cell. These protrusions trapped free-living mitochondria-like bacteria between them. Using the energy gained from being in close contact with bacteria (and using bacterial-derived lipids), cells were able to get bigger and expand the size of their blebs. The sides of the blebs formed the endoplasmic reticulum and their inner surfaces formed the outer membrane of the nucleus, with the original outer membrane of the archaeon becoming what we now call the inner nuclear membrane. Finally, the fusion of blebs with one another led to the formation of the plasma membrane. The result was the eukaryotic cell as we now know it. This inside-out theory is explained in more detail using a diagram in the research article (see notes to editors).

  • The site that yielded the snake — dubbed Sanajeh indicus, or "ancient-gaped one from India" — was located near a village in Gujarat in western India. It was a rich nesting ground for sauropods known as titanosaurs, with evidence for hundreds of egg clutches, each containing about six to 12 round, spherical eggs. Two other instances of fossil snakes found with these clutches suggest the newly described serpent species made its living plundering nests for young dinosaurs. "It would have been a smorgasbord," said researcher Jason Head, a paleontologist at the University of Toronto at Mississauga. "Hundreds or thousands of defenseless baby sauropods could have supported an ecosystem of predators during the hatching season." The dinosaur eggs likely were laid along the sandy banks of a small, quiet tributary and covered afterward by the mother with a thin layer of sediment. These dinosaurs did not seem to look after their young — no evidence for adults has been found at the site. The fact the bones and delicate structures, such as eggshells and the snake's skull, are arranged in anatomical order (as they would appear in real life) points to quick entombment of a serpent caught in the act, as opposed to them all getting washed together after they died. "Burial was rapid and deep," said researcher Shanan Peters, a geologist at the University of Wisconsin. "Probably a pulse of slushy sand and mud released during a storm."

    The last thing hatchling dinosaurs might have seen were giant snakes, researchers say. Scientists found the nearly complete remains of an 11-foot-long, 67-million-year-old serpent coiled around a crushed dinosaur egg right next to a hatchling in the nest of a sauropod dinosaur, the largest animals to have ever walked the Earth. "We think that the hatchling had just exited its egg, and that activity attracted the snake," explained researcher Dhananjay Mohabey, a paleontologist at the Geological Survey of India. "It was such a thrill to discover such a portentous moment frozen in time."
