Study identifies key role of TLK1 and TLK2 enzymes in DNA replication

During cell growth, cells copy their DNA through a process called DNA replication. For this process to be accurate, the genetic and epigenetic information must be copied flawlessly.

Structure of a long-chain lipid that keeps our tears clear revealed

As anyone who has experienced an annoying alternation between dry and watery eyes can confirm, tears alone aren't enough to keep the eye from drying out. A microscopically thin film of oils known as the tear film lipid layer is key to preventing the tear film from evaporating.

Researchers develop new method for capturing dynamic processes in individual cells

Researchers at Karolinska Institutet and Harvard Medical School report in the journal Nature that they have developed a technique for capturing dynamic processes in individual cells. Apart from studying disease processes, the method can be used to observe in detail how specialised cells are formed during embryonic development.

Nanocellulose fibers can reduce fat absorption, research finds

A novel method of reducing the absorption of fat from the gut has recently been granted a US provisional patent. Researchers have demonstrated that the addition of nanocellulose fibres to the food of animals significantly reduces the amount of ingested fat that reaches the bloodstream.

Social environment influences individuality of mice

Individuality is not exclusive to humans. Though this idea was previously rebutted by biologists, today it is accepted that individuality is found in all animal species. It is defined as all the behavior differences between individuals of a single species that are relatively stable over time.
