At Phys.org: How fluctuating oxygen levels may have accelerated animal evolution

"Oxygen levels in the Earth's atmosphere are likely to have "fluctuated wildly" 1 billion years ago, creating conditions that could have accelerated the development of early animal life, according to new research. " Read More ›

At Phys.org: The thinking undead: How dormant bacteria calculate their return to life

This fascinating research presents yet another remarkable example of biochemical complexity with a functionality dependent upon environmental sensing, signal evaluation, operational feedback, managing stored resources, and survivability--all within a supposedly inert "spore." I'll call that evidence of intelligent design. Read More ›

At Phys.org: Discovery of new types of microfossils may answer age-old scientific question

"Scientists have long pondered how and when the evolution of prokaryotes to eukaryotes occurred. A collaborative research team from Tohoku University and the University of Tokyo may have provided some answers after discovering new types of microfossils dating 1.9 billion years." Read More ›

At Phys.org: Scientists are unraveling the mystery of the arrow of time

Researchers: "Fundamentally, the arrow of time arises from the second law of thermodynamics: the principle that microscopic arrangements of physical systems tend to increase in randomness, moving from order to disorder." Apart from ID, nature cannot move towards more complex, functional systems. Read More ›

At Phys.org: Sleeping giant could end deep ocean life

Researchers: "A previously overlooked factor—the position of continents—helps fill Earth's oceans with life-supporting oxygen. Continental movement could ultimately have the opposite effect, killing most deep ocean creatures." Read More ›

At Phys.org: Underwater snow gives clues about Europa’s icy shell

Researchers: "When we're exploring Europa, we're interested in the salinity and composition of the ocean, because that's one of the things that will govern its potential habitability or even the type of life that might live there." Read More ›
