A scientific urban myth

An often-repeated claim is that disease organisms, such as tuberculosis, are ‘evolving’ to become resistant to antibiotics such as penicillin. There’s no doubt that antibiotic-resistant strains of disease organism are becoming prevalent – but is this Darwinian evolution or simply Darwinian myth making? The talk.origins “FAQ” makes repeated reference to the ‘evolution of antibiotic resistance.’ …

Paul Kammerer

Paul Kammerer (17 August 1880, in Vienna – 23 September 1926, in Puchberg am Schneeberg) was an Austrian biologist who studied and advocated the Lamarckian theory of inheritance – the notion that organisms may pass to their offspring characteristics they have acquired in their lifetime. He began his academic career at the Vienna Academy studying …

What Plants Talk About

When we think about plants, we don’t often associate a term like “behavior” with them, but experimental plant ecologist JC Cahill wants to change that. The University of Alberta professor maintains that plants do behave and lead anything but solitary and sedentary lives. What Plants Talk About teaches us all that plants are smarter and …

Can Science and Religion be Integrated?

Can science and religion be integrated? What comes to mind immediately is that religions themselves cannot agree with one another whereas science is basically monolithic. How can there even be trade between the two, let alone integration? … Currently, the overall perception of science is that it is materialist. The belief is that science cannot …

ATP Synthase: New Video Shows Intelligent Design of Molecular Machines in the Cell

ATP Synthase is a molecular machine found in all living organisms. It serves as a miniature power-generator, producing an energy-carrying molecule, adenosine triphosphate, or ATP. The ATP synthase machine has many parts we recognize from human-designed technology, including a rotor, a stator, a camshaft or driveshaft, and other basic components of a rotary engine. This …

Cell Transformation from One Type of Cell to Another

ScienceDaily (Oct. 5, 2011) — Researchers from the Haematopoietic Differentiation and Stem Cell Biology group at the Centre for Genomic Regulation (CRG), have described one of the mechanisms by which a cell (from the skin, for example) can be converted into another which is completely different (e.g., a neuron or hepatic cell). They have discovered …

Plants Found to Send Nerve-Like Messages

PLANTS, unlike animals, have no nerves, so scientists have been jolted by the discovery this month that the tomato plant uses an electric signal to alert its defense system against grazing caterpillars. A team of researchers from England and New Zealand reported in the Nov. 5 issue of Nature that when a leaf on a …

Exploring the Deep – Life under the Sea

Heiko Sahling is a biologist and deep sea geoscientist at the MARUM Research Center. The area he studies is in the Indian Ocean, off the coast of Pakistan. There, at depths down to 3,000 meters, something fascinating is happening. Natural gas is emerging from the sea bed, to produce a surreal world of millions of …
