Extinction of woolly mammoth, saber-toothed cat may have been caused by human predators - 0 views

  •  
    ScienceDaily (July 1, 2010) - A new analysis of the extinction of woolly mammoths and other large mammals more than 10,000 years ago suggests that they may have fallen victim to the same type of "trophic cascade" of ecosystem disruption that scientists say is being caused today by the global decline of predators such as wolves, cougars, and sharks.

The cosmic comic: Riding early waves - 0 views

  •  
    Two fictitious high-spirited scientists of the institute, passionate surfers, take off to visit the early Universe. Not to do serious research there but to experience the ultimate ride on the plasma waves of the big bang. However, they quickly realize that they would be stuck without their knowledge of the physics of the early Universe.

Radical New Theory: Black Holes Attack and Devour Stars from the Inside - Space.com - 0 views

  •  
    As if they weren't considered beastly enough, black holes can dive into nearby stars and devour them from the inside out, scientists now suggest. Such invasions by such black holes could help explain the most powerful explosions in the universe, gamma-ray bursts, whose origins remain elusive.

Mystery of Bird Maleness Partly Solved - 0 views

  •  
    In a recent study, researchers show that a gene called DMRT1 found only on the Z chromosome partly explains bird "maleness". When a ZZ embryo gets less DMRT1, the embryos start to take on some female traits. These studies show us that bird gender can be partly explained by genetics. Not having enough of a single gene can keep a bird from becoming a bona fide male bird. But this doesn't rule out the possibility of a female gene being on the W chromosome. Scientists just haven't yet found one.

Long hot summer of fire and floods fit predictions - 1 views

  •  
    (AP) -- Floods, fires, melting ice and feverish heat: From smoke-choked Moscow to water-soaked Pakistan and the High Arctic, the planet seems to be having a midsummer breakdown. It's not just a portent of things to come, scientists say, but a sign of troubling climate change already under way.

Monkeys recognize themselves in the mirror, indicating self-awareness | KurzweilAI - 0 views

  •  
    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.

The gene-environment enigma - 0 views

  •  
    ScienceDaily (Dec. 3, 2010) - Personalized medicine centers on being able to predict the risk of disease or response to a drug based on a person's genetic makeup. But a study by scientists at Washington University School of Medicine in St. Louis suggests that, for most common diseases, genes alone only tell part of the story.

Breakthrough chip technology lights path to exascale computing: Optical signals connect... - 0 views

  •  
    ScienceDaily (Dec. 3, 2010) - IBM scientists have unveiled a new chip technology that integrates electrical and optical devices on the same piece of silicon, enabling computer chips to communicate using pulses of light (instead of electrical signals), resulting in smaller, faster and more power-efficient chips than is possible with conventional technologies.

Do our bodies' bacteria play matchmaker? - 0 views

  •  
    Based on a theory developed by Prof. Rosenberg and Dr. Ilana Zilber-Rosenberg, the scientists propose that the basic unit of natural selection is not the individual living organism, plant or animal, but rather a larger biological milieu called a holobiont. This milieu can include plant or animal life as well as their symbiotic partners. In the case of animals, these partners tend to be microorganisms like intestinal bacteria.
