Spin or Sin

November 1, 2011

You are bureau chief for a science news organization. Your job is to convince the public that science is right, and their doubts are wrong. You believe in reason and evidence, but you are frustrated that large segments of the population doubt the scientific consensus on certain hot-topic issues. The way to reach them, you say, is by coaxing people they already respect to convey the message, and use graphics to present the evidence. Sound reasonable?

Caveman’s Best Friend, Evolution’s Newest Upset

October 29, 2011

The evolutionary story of the dog-human relationship has had to be drastically revised in light of recent findings. The old story was that wolves tamed themselves into doggish behavior some 15,000 years ago in Asia by frequenting human garbage dumps. Evidence from caves, fossil prints, and the dog genome, though, has required a near complete overhaul of how our animal companions and their relationships to humans evolved, calling into question whether evolution was involved at all.

The Blind Men and the Ape Man

October 25, 2011

“We have all seen the canonical parade of apes, each one becoming more human. We know that, as a depiction of evolution, this line-up is tosh. Yet we cling to it. Ideas of what human evolution ought to have been like still colour our debates.” So said Henry Gee, editor of Nature. Are other icons coloring scientists’ views of human origins? How close are they to describing scientifically where we come from?

Your Motor/Generators Are 100% Efficient

October 14, 2011

ATP synthase astounds again. The molecular machine that generates almost all the ATP (molecular “energy pellets”) for all life was examined by Japanese scientists for its thermodynamic efficiency. By applying and measuring load on the top part that synthesizes ATP, they were able to determine that one cannot do better at getting work out of a motor – a motor that is also a generator.

Evolutionary Guru Deceives Himself

October 12, 2011

Maybe you’ve had this experience: you’re in class, taking notes, and after a long lecture, the teacher realizes something wrong, and announces, “Forget everything I just said.” Frustrating, isn’t it? That’s what a recent article on evolution did. An evolutionary psychologist explained the origin of lying, then admitted he is self-deceived.

Biomimetics to the Rescue of Science

October 10, 2011

The booming field of biomimetics (imitating nature’s designs) is fascinating not only for the amazing products it promises, but for the fresh new opportunities it provides for science and engineering. From viruses to mammals, everything in the living world is now being seen in a new light: agents of innovation that humans can learn from. Here are just a few examples in recent news, arranged in order from large to small inspirational creatures.

Mighty Mitochondria Conduct Energy Exquisitely

October 7, 2011

None of us could live without mitochondria. These are the power centers ubiquitous in eukaryotic cells. They contain molecular machines in factories whose jobs are to generate and conduct electrical currents. The currents run turbines that packetize the energy in molecules of ATP, which are then used by most processes in the cell. New discoveries continue to fascinate scientists with how mitochondria work. Some scientists use their energy to find ways Darwinian evolution could build the machinery of life.

Human Cloning Advanced Despite Ethics

October 6, 2011

A researcher in New York obtained women’s eggs and conducted experiments on them that could lead to human cloning. While done in the name of regenerative medicine, the experiments on embryonic stem cells involved the destruction of a human embryo. This kind of experimentation raises multiple ethical concerns, but the researcher went ahead anyway, and scientific journals are hailing the advance, albeit with a palpable twinge of conscience about ethics.

Of Minds and Men

October 3, 2011

It takes a mind to know one. Can cognizant, sentient minds evolve from slime? Most of the secular science press takes it for granted. Here’s a journey into storybook land, where imaginative reporters see visions of slime climbing out of the mud to look back at an unobservable history of matter becoming mind.

From recent scientific discoveries, here’s a look at a few mechanisms under our skin that not only keep us alive, but provide us with a shopping mall of good things.

It’s Still a Rare Earth

September 25, 2011

Now that hundreds of extrasolar planets are known, how do they compare to ours? The Kepler spacecraft has found a varied assortment of all sizes and distances away from their parent stars. Only a few reside in their star’s habitable zones. But that’s only the first of many requirements for life. Two recent studies indicate that Earth remains a rare bird in the celestial aviary.

Stretching Credibility in Evolutionary Stories

September 20, 2011

Improbable events happening numerous times; selective extinctions; voodoo phylogenetics – at what point do evolutionary explanations exceed the threshold of credibility a trusting public grants to the gurus of the culture, scientists?

Psychotherapy: Needs Reboot? or Just Boot?

September 14, 2011

The word “reboot” assumes a prior boot. You can’t reboot something that never booted up in the first place. The American Psychological Association is calling for “rebooting psychotherapy.” Is it even booted up? The press release begins with an admission that questions whether psychotherapy ever got powered on.

Human Genome Individuality Adds New Questions

September 13, 2011

Mission accomplished: “The Human Genome Project” was in the bag by 2003. Now we understand how humans are genetically wired, right? Not so fast. Another human genome was just published, raising a whole new set of questions. The big issue is that we all have two genomes in one – one from each parent. Biologists knew this, of course, but for the first time, those two genomes were untangled from one another, and a lot of differences were found: two million, in fact. How do our two separate genomes behave toward each other? And if genomes differ this much, what does a concept like “the human genome” really mean?

Are Embryonic Stem Cells Obsolete?

September 11, 2011

Adult stem cells can apparently do everything embryonic stem cells can – and they are moving regenerative medicine forward faster, with more results. Since the use of human embryos for research is ethically repugnant to many people, what motivations remain to continue the practice? Here is a rapid-fire list of stem cell news this month:
