The redpoll finch saga: How two bird species just became one

This week, birders around the world lost one beloved feathered creature from their birding life list. Fortunately, no species went extinct. Instead, this change resolved a long-held misunderstanding about the redpoll finch.

Bridging the 'valley of death' in carbon capture

Mitigating the effects of climate change has become a major focus worldwide, with countries and international organizations developing various strategies to address the problem. Lowering CO2 emissions is at the top, with ...

Quantum microscopy study makes electrons visible in slow motion

Physicists at the University of Stuttgart under the leadership of Prof. Sebastian Loth are developing quantum microscopy which enables them for the first time to record the movement of electrons at the atomic level with both ...

Scientists develop new AI method to create material 'fingerprints'

Like people, materials evolve over time. They also behave differently when they are stressed and relaxed. Scientists looking to measure the dynamics of how materials change have developed a new technique that leverages X-ray ...

Researchers achieve unprecedented nanostructuring inside silicon

Silicon, the cornerstone of modern electronics, photovoltaics, and photonics, has traditionally been limited to surface-level nanofabrication due to the challenges posed by existing lithographic techniques. Available methods ...

In philosophy, the theory of materialism holds that the only thing that exists is matter; that all things are composed of material and all phenomena (including consciousness) are the result of material interactions. In other words, matter is the only substance. To many philosophers, not only is 'physicalism' synonymous with 'materialism', but they use both words to describe a position that supports ideas from physics which may not be matter in the traditional sense (like anti-matter or gravity). Therefore much of the generally philosophical discussion below on materialism may be relevant to physicalism. Also related are the ideas of methodological naturalism (i.e. "let's at least do science as though physicalism is true") and metaphysical naturalism (i.e. "philosophy and science should operate according to the physical world, and that's all that exists"). The philosophical alternatives to materialism are some forms of monism (besides the materialistic monism), dualism and idealism.
