Pinning down when specific events occurred is often tricky, though. For this, biologists depend mainly on dating the rocks in which fossils are found, and by looking at the "molecular clocks" in the DNA of living organisms. There are problems with each of these methods. Modern genetics allows scientists to measure how different species are from each other at a molecular level, and thus to estimate how much time has passed since a single lineage split into different species.

Paleoanthropology, genetics and evolution. I have a review of Marlene Zuk's new book, Paleofantasy , in this week's Nature : "Evolutionary biology: Twisting the tale of human evolution"  . I can't replicate my review here, but for people who have access to Nature I thought I'd bring attention to it.

But the New York Times reports: A review of studies has found that the health benefits of infant male circumcision vastly outweigh the risks involved in the procedure. Actually, it doesn’t. Not at all. The paper is all about the frequency of circumcision in the US; this is the only real data in the paper, and notice that a good chunk of it is speculation. Prevalence of adult circumcision in the United States during the past 6 decades (1948-2010). Bad Astronomy. Well now, this is an interesting discovery: astronomers have found what looks like a "super-Earth" – a planet more massive than Earth but still smaller than a gas giant – orbiting a nearby star at the right distance to have liquid water on it!
Given that, it might – might – be Earthlike. This is pretty cool news. We’ve found planets like this before, but not very many! And it gets niftier: the planet has at least five siblings, all of which orbit its star closer than it does. Now let me be clear: this is a planet candidate; it has not yet been confirmed. Science. Science - News for Your Neurons. The Loom. Your hands are, roughly speaking, 360 million years old.
Before then, they were fins, which your fishy ancestors used to swim through oceans and rivers. Once those fins sprouted digits, they could propel your salamander-like ancestors across dry land. Fast forward 300 million years, and your hands had become fine-tuned for manipulations: your lemur-like ancestors used them to grab leaves and open up fruits. Within the past few million years, your hominin ancestors had fairly human hands, which they used to fashion tools for digging up tubers, butchering carcasses, and laying the groundwork for our global dominance today.

Jul 29 2016 An Artificial Leaf We are currently in a transition period from an economy based largely on fossil fuels to one based largely on renewable or carbon-neutral fuels.
Even if we put aside the question of global warming, there are many good reasons to make this transition. Fossil fuel pollution results in billions of dollars of health care costs and lost productivity each year. For any nation, the ability to create more of their own fuel and be less dependent on oil imports can have economic benefits. Of course, if you accept the scientific consensus on anthropogenic global warming, we may just avoid some unwanted consequences of dumping billions of tons of previously sequestered carbon back into the atmosphere (40 billion tons in 2015 alone).
