Breeding for bigger cattle may come with hidden fertility trade-offs

A University of Queensland analysis of genetic data from northern Australian cattle has identified key regions of the genome that influence traits like fertility, growth and body condition, sometimes all at the same time. ...

A new protein timeline explains plasma membrane repair

In the evolutionary history of life, the ability of a cell to separate its inner world from the external environment was an important turning point. The so-called plasma membrane lets cells control what gets in and out and ...

Why averages fail for bacteria in the open ocean

How can bacteria that forage on organic particles survive in vast ocean regions where such particles are extremely sparse? A new study by researchers from ETH Zurich and Queen Mary University of London shows that variability ...

Cornwall ocean study highlights value of low-cost eDNA tests

Environmental DNA (eDNA) tests can identify genetic material left by organisms in the environment, such as cells and excrement, but surveys of ocean wildlife can be difficult and expensive, and standard eDNA tests are also ...

How a protein pair ensures that faulty mRNA is destroyed

Nonsense-mediated mRNA decay (NMD) is one of the most important processes in our cells to ensure that no faulty or incomplete proteins are produced. Scientists have now identified a central mechanism behind this control system.

A new clue to how the body detects physical force

Every time we feel a gentle tap on the skin, specialized nerve cells convert that physical force into an electrical signal the brain can interpret as touch. While scientists have long known that a protein called PIEZO2 acts ...

A new 'molecular switch' for inborn immunity identified

Innate immune sensors—known as pattern recognition receptors (PRRs)—detect specific molecular components of bacterial or viral intruders. The PRRs forward the signals which results in the production of interferons, which ...
