Tuning biomolecular receptors for affinity and cooperativity

Our biological processes rely on a system of communications -- cellular signals -- that set off chain reactions in and between target cells to produce a response. The first step in these often complex communications is the moment a molecule binds to a receptor on or in a cell, prompting changes that can trigger further signals that propagate across systems. From food tasting and blood oxygenation during breathing to drug therapy, receptor binding is the fundamental mechanism that unlocks a multitude of biological functions and responses.

Tracking evolution of SARS-CoV-2 virus mutations

Researchers tracked the mutation rate in SARS-CoV-2 virus's proteome -- the collection of proteins encoded by genetic material -- through time, starting with the first SARS-CoV-2 genome published in January and ending more than 15,300 genomes later in May. The team found some regions still actively spinning off new mutations, indicating continuing adaptation to the host environment. But the mutation rate in other regions showed signs of slowing, coalescing around single versions of key proteins.

War songs and lullabies behind origins of music

Love is not the primary reason humans developed music. A new evolutionary theory of the origins of music argues more evidence supports music coming from the need for groups to impress allies and foes, and for parents to signal their attention to infants. They also argue against the theory that making music arose out of a need for social bonding, or that it is 'auditory cheesecake' a fancy evolutionary byproduct with no purpose.

Plant genetic engineering to fight 'hidden hunger'

More than two billion people worldwide suffer from micronutrient malnutrition due to deficiencies in minerals and vitamins. Poor people in developing countries are most affected, as their diets are typically dominated by starchy staple foods, which are inexpensive sources of calories but contain low amounts of micronutrients. Researchers now explain how plant genetic engineering can help to sustainably address micronutrient malnutrition.
