These non-random epigenetic changes imply that evolution has a “mind.” Creatures appear to have complex mechanisms to make epigenetic changes that allow them to adapt to future environmental challenges. But where did this forward-thinking design come from? Evolution is mindless; it cannot see the future. So how could it evolve mechanisms to prepare for the future?

But God does! God is omniscient (all-knowing), and He foreknew Adam and Eve would sin. He would judge that sin (Gen. 3) and the world would be cursed (Rom. 8:22). God knew that organisms would need the ability to adapt in a world that was no longer “very good.” God likely designed organisms with epigenetic mechanisms to allow them to change easily and quickly in relation to their environment. These types of changes are much more valuable than random mutation and natural selection because they can produce immediate benefits for offspring without harming the basic information in the actual sequence of DNA.

Although we often hear that “nothing in biology makes sense except in the light of evolution,” it should be said that “nothing in biology makes sense without the Creator God.” Epi genetics is an exciting field of science that displays the intelligence and providence of God to help organisms adapt and survive in a fallen world.

The goal of “Femtochemistry” is to film and control chemical reactions with short flashes of light. Using consecutive laser pulses, atomic bonds can be excited precisely and broken as desired. So far, this has been demonstrated for selected molecules. Researchers at the University of Göttingen and the Max Planck Institute for Biophysical Chemistry have now succeeded in transferring this principle to a solid, controlling its crystal structure on the surface. The results have been published in the journal Nature.

The team, led by Jan Gerrit Horstmann and Professor Claus Ropers, evaporated an extremely thin layer of indium onto a silicon crystal and then cooled the crystal down to −220 degrees Celsius. While the indium atoms form conductive metal chains on the surface at room temperature, they spontaneously rearrange themselves into electrically insulating hexagons at such low temperatures. This process is known as the transition between two phases – the metallic and the insulating – and can be switched by laser pulses. In their experiments, the researchers then illuminated the cold surface with two short laser pulses and immediately afterwards observed the arrangement of the indium atoms using an electron beam. They found that the rhythm of the laser pulses has a considerable influence on how efficiently the surface can be switched to the metallic state.

This effect can be explained by oscillations of the atoms on the surface, as first author Jan Gerrit Horstmann explains: “In order to get from one state to the other, the atoms have to move in different directions and in doing so overcome a sort of hill, similar to a roller coaster ride. A single laser pulse is not enough for this, however, and the atoms merely swing back and forth. But like a rocking motion, a second pulse at the right time can give just enough energy to the system to make the transition possible.” In their experiments, the physicists observed several oscillations of the atoms, which influence the conversion in very different ways.

Magnetotactic bacteria have magnetosomes with which they can sense magnetic field lines. This allows magnetotactic bacteria to swim towards North or South to find the perfect location in the deep and dark water.

As sales of electric vehicles start to soar, the thorny issue of what to do with end-of-life lithium-ion batteries isn’t going away. We look at the problem and explore the solutions.

To say that the legacy of today’s electric vehicles is set to be a mountain of lithium-ion battery waste would be kind. In 2017, when worldwide sales of electric vehicles exceeded one million cars per year for the first time, calculations from UK-based University of Birmingham researchers revealed stark figures. These vehicles alone are destined to leave some 250,000 tonnes of unprocessed battery waste when they eventually reach the scrap heap in 2027. This is just the beginning.

Latest modelling from the Paris-based International Energy Agency indicates the number of electric cars on the road will lie between 125 million and 220 million by 2030. Given this, come the middle of this century, the 250,000-tonne waste figure looks meagre against the tens of millions of tonnes of waste that could follow. And to make matters worse, recycling is playing catch-up.

In this article, Jonathan Tennenbaum constructs – conceptually – a hydrogen-boron fusion reactor similar to one proposed by Australian plasma physicist Heinrich Hora.

Hora’s approach is one of many – in various stages of development – proposed for achieving nuclear fusion power. I don’t intend to endorse one idea over another but writing about Hora’s extremely promising concept is an excellent way to acquaint readers with some of today’s most exciting areas of science and technology.

Ideally, readers should be familiar with the preceding articles in this series and the following pieces of the puzzle:
