Tiny protein has big impact in times of stress

Ribosomes churn out proteins that carry out all of life's functions, but when missing a key and previously overlooked factor, they can break down in times of stress, Yale University scientists have discovered. 

We reconstructed the genome of the 'first animal'

The first animals emerged on Earth at least 541m years ago, according to the fossil record. What they looked like is the subject of an ongoing debate, but they're traditionally thought to have been similar to sponges.

Moulds produce plant growth hormone

Plants, bacteria and various fungi produce a specific group of hormones known as auxins. Together with other hormones, they cause plant cells to stretch and thus, for example, the rapid growth of young shoots. The manner ...

Mapping biological functions of NUDIX enzymes

In a large multidisciplinary project, researchers at Karolinska Institutet have explored different properties of an enzyme family called NUDIX hydrolases. The study, published in Nature Communications, reveals novel insights ...

SIRT6 ability to suppress cancer cell growth is explained

For several years, scientists have known that SIRT6 – one of seven sirtuins, a family of mammalian proteins with important biological functions, including promoting longer, healthier life – is a tumor suppressor. It has ...

When ions and molecules cluster

The electric charge of atoms or molecules zaps science's ability to predict how these ions will behave when combined with others. Different ions with the same charge cause different effects. How an ion behaves when isolated ...
