When the baby comes, working couples no longer share housework equally
When highly educated, dual-career couples have their first child, both spouses think the baby increases their workloads by equal amounts -- but a new study suggests that's not true.

Genetic changes to basic developmental processes evolve more frequently than thought
Newly evolved genes can rapidly assume control over fundamental functions during early embryonic development, report scientists from the University of Chicago. They identified a gene, found only in one specific group of midge flies, which determines head and tail patterning in developing embryos, similar to an unrelated, previously-known gene found in certain fruit fly families. The findings suggest that evolutionary changes to the genetics of fundamental biological processes occur more frequently than previously thought.

Light in sight: a step towards a potential therapy for acquired blindness
A promising new therapeutic approach for hereditary blindness based on a technology termed 'optogenetics' is to introduce light-sensing proteins into these surviving retinal cells, turning them into 'replacement photoreceptors' and thereby restoring vision. However, several factors limit the feasibility of a clinical optogenetic therapy using traditional light-sensitive proteins, as they require unnaturally high and potentially harmful light intensities and employ a foreign signaling mechanism within the target retinal cells.

As life slips by: Why eye movement doesn't blur the picture
Researchers at University of California, San Diego School of Medicine and Shiley Eye Institute have identified the molecular 'glue' that builds the brain connections that keep visual images clear and still, even as objects or your eyes move. Using mouse models, the researchers demonstrate that image stabilization depends upon two proteins, Contactin-4 and amyloid precursor protein, binding during embryonic development.

Penn team finds protein 'cement' that stabilizes the crossroad of chromosomes
A new study describes how the centromere is stabilized during replication. The structure and biology of the centromere is of considerable scientific interest because problems with it can lead to abnormalities in the chromosomes of daughter cells, which are the basis of such disorders as Down syndrome. As it turns out, the centromere is distinguished not only by its DNA sequence but also by a special type of nucleosome, which includes a protein called CENP-A.

Securing the supply of sea scallops for today and tomorrow
Good management has brought the $559 million United States sea scallop fishery back from the brink of collapse over the past 20 years. However, its current fishery management plan does not account for longer-term environmental change like ocean warming and acidification that may affect the fishery in the future. A group of researchers from Woods Hole Oceanographic Institution, NOAA's National Marine Fisheries Service, and Ocean Conservancy hope to change that.

Tiny silicone spheres come out of the mist
Technology in common household humidifiers could enable the next wave of high-tech medical imaging and targeted medicine, thanks to a new method for making tiny silicone microspheres developed by chemists at the University of Illinois. The researchers made silicone microspheres with a variety of properties for different applications, including colored, fluorescent and magnetic spheres.

From the depths of a microscopic world, spontaneous cooperation
A clever combination of two different types of computer simulations enabled a group of Illinois researchers to uncover an unexpectedly cooperative group dynamic: the spontaneous emergence of resource sharing among individuals in a community. Who were the members of this friendly, digitally represented collective? Escherichia coli, rod-shaped bacteria found in the digestive systems of humans and many other animals.

Extreme excavation: Fire ant style
Scientists from the Georgia Institute of Technology, USA, have investigated how fire ants excavate their impressive nests using complex 3-D CT-scanning and discovered that the pests are successful invaders because they are able to construct nests regardless of grain size, in addition to showing how the ants manipulate soil granules while removing spoil from their tunnels.

Defects in atomically thin semiconductor emit single photons
Researchers at the University of Rochester have shown that defects on an atomically thin semiconductor can produce light-emitting quantum dots. The quantum dots serve as a source of single photons and could be useful for the integration of quantum photonics with solid-state electronics -- a combination known as integrated photonics.

Study shows where damaged DNA goes for repair
New research sheds light on the process of DNA repair in the cell. Expanded repeats of the CAG/CTG trinucleotide in yeast shift to the periphery of the cell nucleus for repair. This shift is important for preventing repeat instability and genetic disease. Going out to the 'repair shop' at the nuclear periphery is a previously unrecognized yet important step to maintain repetitive DNA and to prevent damage to chromosomes.
