Pseudogenes are widely considered to be non-functional parts of the genome. New work has uncovered the phenomenon of pseudo-pseudogenes in the olfactory receptor repertoires of drosophilids that encode for functional receptor proteins through neuron-specific read-through of premature termination codons.

Mechanical properties, such as stiffness, promise to provide new biomarkers and diagnostic indicators for underlying disease of biological organisms, from cells to organs. However, existing technology is invasive and/or too slow to provide mechanical information of large samples at high resolution. A new optical configuration that speeds up the acquisition by ~100 times is described below.

The loss of the entire X chromosome in Drosophila results in a genome-wide aneuploid effect. During evolution, this effect drifted gradually from the X-chromosomes to the autosomes in a wide range of species, which depicts that transacting regulatory modifiers counteract their targets in two separate chromosomes. These modifiers are hyper-activated in dosage compensated males and eventually mitigate inverse aneuploid effects for maintaining the equality in autosomal target gene expression in both...

The brain is never idle. Even when we do nothing, during sleep for instance, it is very active. This activity displays a certain structure, and how this arises is not known. We have now shown this structure to obey well-known brain anatomical principles.

Signals from the gut microbiota participate in the maintenance of host metabolic homeostasis. A new investigation reveals the molecular mechanism underlying the effect of diet-dependent gut flora dysbiosis on the induction of circadian gene transcription in the liver.

microRNAs interact with many mRNAs through conserved binding sites, and are therefore believed to control more than 60% of mammalian coding genes. But various biases in current experimental and computational methods generate high rates of false positives: many published microRNA/mRNA interactions are thus likely to be biologically inconsequential.

Vitamins A and C can enhance success in the challenging process of converting adult cells into stem cells. We report that the way these vitamins complement each other to do this is by erasing 'epigenetic memory' associated with DNA, which could help improve technologies geared towards regenerative medicine and stem cell therapy.

Microtubules are rigid filament components of the cytoskeleton. They are continuously regenerating and have a half-life of only a few minutes. Microtubules grow steadily from the centre of the cell towards the periphery but can randomly disassemble at any moment.

In mammals, parent-specific DNA methylation marks are required to control the parent-of-origin expression of imprinted genes. Disruption of these marks results in a variety of phenotypes, ranging from early embryonic lethality to neurodegenerative syndromes and cancer.

DNA is under constant attack, which can cause unwanted genetic mutations and cancer. Luckily, our cells have a host of DNA repair proteins, which help to fix most of the damage. A new study takes a look at how 53BP1, a key DNA repair protein, is recruited to sites of DNA breaks.
