The modern synthesis view that random genetic mutations and natural selection drive evolution has predominated in science for almost a century. More recently, experimental evidence, made possible by advanced technological methods, is challenging this view.

Clinical cytogenetics looks at the relationship of human disease and chromosomes, the long DNA molecules that contain an organism's genetic material. Historically, cytogenetics enabled the identification of the abnormal chromosomes responsible for Down syndrome and chronic myeloid leukemia, among other discoveries.

If life emerged from non-life, as many scientists hold, how did this dead matter begin to think? Two longtime chemists discussed this question in a perspective published in the Dec. 3, 2022, issue of the journal Life.

A team of researchers in the Department of Biomolecular Sciences at the Weizmann Institute of Science in Israel examined how four enzymes that generate sphingolipids and their precursor metabolic pathways might have evolved.

The researchers conclude that current models for the origin of life fail to provide evidence for the evolution of these metabolic pathways, which are necessary for sphingolipid synthesis.

Newly discovered evidence shows that a flawed 1956 report issued to the public by the U.S. National Academy of Sciences (NAS) played a large role in establishing the erroneous yet widespread view that ionizing radiation at any level is dangerous.

Current Science Daily | April 2022

Duke University professor Adrian Bejan's book, Time and Beauty: Why Time Flies and Beauty Never Dies, examines how physics explains our everyday perceptions of time and beauty.

The current prevailing view in biological science is that the DNA of mitochondria, the structures that convert nutrients into cellular energy, is passed on only through maternal inheritance. How this idea came to be, and a theory on why it's wrong, is the subject of a review paper by physical anthropologist Jeffrey H. Schwartz.

Professor Mark McMenamin, a Mount Holyoke College geologist, chanced upon a dark-colored fossil bone dating to the Lower Jurassic period, between 201 million and 174.1 million years ago.

A prevailing scientific scenario for the chemical origin of life focuses on RNA (ribonucleic acid) and proteins, biopolymers without which there would be no life today. But a new study suggests that it's not plausible that these complex molecules could spontaneously appear prebiotically.

Current Science Daily | October 2021

A research team from the Department of Genetics, Evolution and the Environment, at University College, London, has developed a computational and evolutionary model that sheds light on the processes involved in mitochondrial inheritance for humans and mice.

In an intriguing look at the origins of cognition and technology in nature, theoretical chemist Addy Pross is exploring how nature discovered its own laws twicefirst unconsciously and later consciously.

In the view of Douglas H. Erwin, senior research biologist and curator of Paleozoic invertebrates at the Smithsonian's National Museum of Natural History in Washington, D.C., evolutionary novelty precedes innovation. He has compared novelty to an invention with a patent, whereas innovation is like an economically significant invention. In biology an example of an innovation would be a change in the structure of ecological communities.

Cyanobacteria has become a familiar word in areas where there are freshwater lakes and ponds because their rapid growth produces toxins that make humans sick and can kill wildlife or pets who drink the water. Cape Cod, Massachusetts, famous for its ocean beaches and freshwater ponds, has a two-pronged approach to monitoring and preventing cyanobacteria blooms.

Entomologist and author Douglas Tallamy proposes a practical way that anyone with a patch of outdoor space can help restore environmental balance: Reduce your amount of grass, plant some keystone native species and change outdoor lights to yellow.
