An alternative model in which the universe is 26.7 billion years old and needs neither dark matter nor dark energy has held up against several major cosmology tests, according to a new University of Ottawa study. The research, titled "A Big Bang Nucleosynthesis Consistency Test of the CCC+TL Cosmology," is published in the journal Universe.

How a metabolite protects the enzyme that consumes it

Metabolites are consumed by enzymes to produce other vital molecules as well as to control metabolite levels. But how do cells avoid consuming too much? Researchers from the MPI of Biochemistry, with the University of Nevada, Las Vegas, and the de Duve Institute in Brussels, have

Light-powered method resurrects 'dead-end' compounds for drug discovery

Throughout the drug development process, which can take a decade or more, tens of thousands of chemical compounds are produced that never go on to become medicines. A Florida State University researcher is part of a team that has discovered a new way to give some of these "dead e
