New Recipe for Life: Zinc & Zap

September 5, 2009

Two scientists are overturning the Miller icon of the origin of life – you know, the illustration in almost every textbook showing sparks zapping gases and amino acids emerging from the goo. That doesn’t wash any more, claim Armen Mulkidjanian (University of Osnabrueck) and Michael Galperin (U.S. National Institutes of Health). Instead, Astrobiology Magazine reported, […]

Milking the Martian Meteorite

September 1, 2009

One would think everything has been told about ALH 84001, the Martian meteorite that made a splash in 1996 with claims it contained fossils of living organisms. That claim was essentially discarded in subsequent years. Its major contribution was giving life to a new science called astrobiology and energizing NASA’s Mars program. Now, a new […]

Emergence of Genetic Code Touted

August 31, 2009

Most origin-of-life researchers have acknowledged the extreme improbability of the genetic code arising by chance. Their approaches to get around this problem have varied considerably since the Miller experiment succeeded in generating a few amino acids. Despite the celebrations that 1953 experiment generated (05/02/2003), it did not even begin to approach the problem of solving […]

Twitter the ET Bandwidth Wagon

August 16, 2009

If you have nothing better to do, send a message to an alien. Leonard David reported on Space.com that a website in Australia is collecting messages to beam up to a planet named Gliese 581d that is 20.3 light-years away. Even a Senator who is Australia’s Minister for Innovation, Industry, Science and Research got involved. […]

Comet-Ocean Theory Gets Another Splash

August 13, 2009

National Geographic News gave some halfway-enthusiastic press to another recurrence of a theory that circulates from time to time – that earth got its ocean water from comets. They gave air time to work by Uffe Jorgensen and a team from the Niels Bohr Institute in Denmark that concludes “comets were the culprits” in the […]

Mars Looks More Hostile to Life

August 6, 2009

The methane Mars produces gets destroyed rapidly. This is leading some planetary scientists to get depressed about the possibility of finding life there. The BBC News, Space.com and New Scientist all reported on the paper in Nature,1 saying this represents bad news for life. In models by Franck Lefevre and Francois Forget, patterns […]

Lightning Cooks Up Weird Science

July 13, 2009

Get a charge out of this headline from New Scientist. A couple of scientists from University of Arizona studied fulgurites, the structures formed in sand by lightning strikes. They found that they contain phosphites (oxidized phosphate molecules). They theorized that lightning strikes could have provided phosphites which the primordial soup used to build RNA and […]

Origin-of-Life Researchers Caught Playing With Toys

July 7, 2009

A “virtual primordial soup” cooks up life in a computer program in a “toy universe,” according to reporter Leslie Mullen at Space.com. She wrote, “The power of computer processing could one day solve the riddle of life’s origin.” EvoGrid is “a computer creation concept that would be a digital version of the primordial […]

Salting News with the L Word Life

June 25, 2009

Small amounts of sodium were detected in ice particles erupting from Saturn’s moon Enceladus. Deduction: this might lower the melting point of underground ice, forming subsurface pockets of liquid water – perhaps an ocean. Conclusion: Life! It doesn’t matter that Enceladus has no other factors conducive to life than water, or that salt is generally […]

We Know Less Than We Think

June 23, 2009

Strange reports come from science news outlets on occasion that call into question facts we thought we understood. These raise a question: do we really know what we think we know? Cutting dinosaurs down to size: Dinosaurs may have been half as heavy as thought, said Science Daily. Some paleontologists are claiming that widely-used methods […]

This Place Really Has Atmosphere

June 11, 2009

Of all the bodies in the solar system, only eight have a substantial atmosphere. If you add in those with tenuous atmospheres, you can add in Triton and Mercury, and maybe a few others, till it becomes pedantic to call it an atmosphere if there are only a few short-lived molecules hovering over a moon.

Key Step in Origin of Life Declared

May 15, 2009

The popular “RNA World” scenario for the origin of life has long suffered from a big hurdle: the implausibility of getting the key components of RNA building blocks, called nucleotides, from joining together. Each nucleotide requires a ribose sugar, a pyrimidine base, and a phosphate group. Now, a team publishing in Nature tried a new […]

Mooning the Public: Life Sells

April 27, 2009

Advertisers have known for a long time that sex sells. That’s why ads often include a scantily-clad woman standing next to the pickup truck for sale. It seems that in planetary science, life sells. An icy moon can be a pretty dull thing, but announce that there might be life there, and eye appeal jumps. […]

A Darwinist Religious Experience Described

April 11, 2009

As millions of Jews celebrate Passover, and as millions of Christians gather to celebrate Easter, a Darwinist reporter was experiencing “existential vertigo” – a sweeping sense of dizziness as her imagination zoomed in and out of the implications of her faith. It may be the closest thing that a secular materialist can call a religious […]

Did Nature Dictate Biological Codes?

April 9, 2009

Pangloss was a character in Voltaire’s Candide made to caricature philosophers who give simplistic, optimistic answers to difficult questions. Dr. Pangloss was fond of saying, a la Leibniz, that we live in the best of all possible worlds. One evolutionist described a theory by two other evolutionists as possibly a “Panglossian argument” about the origin […]
