Improved understanding of protein complex offers insight into DNA replication initiation mechanism basics

A clearer understanding of the origin recognition complex – a protein complex that directs DNA replication – through its crystal structure offers new insight into fundamental mechanisms of DNA replication initiation. This will also provide insight into how ORC may be compromised in a subset of patients with Meier-Gorlin syndrome, a form of dwarfism in humans.

Argonne researchers will be working with Chicago’s Pace Suburban Bus and Metra Commuter Rail Service to improve the detection, analysis and response to emergencies and how best to evacuate the city in a major emergency under a $2.9 million grant announced this week by the U.S. Department of Transportation’s Federal Transit Administration. The project will result in tools that can be used by cities across the country and will utilize the massive computing resources available at Argonne to conduct highly complex modeling and simulation of transportation systems.
Argonne researchers to study Chicago emergency evacuation system

A group of Argonne researchers will be studying methods and creating tools for building more resilient mass transit systems to evacuate major cities under a $2.9 million grant announced today by the U.S. Department of Transportation’s Federal Transit Administration.

In a study published in Nature Chemistry, Northwestern researchers have discovered that in the mammalian egg, zinc is stored in tiny packages just below the cell surface. These packages are released in waves following fertilization in events called ‘zinc sparks.’ These sparks are akin to neurotransmitter release in the brain or insulin release in the pancreas. This fluorescence image of an egg labeled for zinc (green) and DNA (blue) depicts how the egg stores zinc in thousands of tiny packages. These are released during fertilization to form the zinc spark. Image credit: Northwestern University. Click to view larger.
Stunning zinc fireworks when egg meets sperm

Sparks literally fly when a sperm and an egg hit it off. The fertilized mammalian egg releases from its surface billions of zinc atoms in “zinc sparks,” one wave after another, found a Northwestern University-led interdisciplinary research team that includes experts from the Advanced Photon Source at Argonne.
