Two studies presented at Society for Neuroscience Meeting (NOTE: Thise release has been updated since its original post.)
Scientists at the OHSU Oregon National Primate Research Center and the University of Pittsburgh report significant stress early in life can have varying lifelong impacts depending of the timing of the stress exposure. The research also demonstrates that the impact can become even more profound when coupled with stress in adulthood. In a related but separate study, the researchers also observed the importance of timing in initiating therapies meant to counteract the impacts of early life stress. The research is being presented this week at the 2004 Society for Neuroscience meeting in San Diego.
“Past research conducted in both humans and animals has already established that significant stresses experienced early in life can cause problems in the development of social skills and behavioral problems that can last throughout childhood and into adulthood,” said Judy Cameron, Ph.D., a scientist in the divisions of Reproductive Sciences and Neuroscience at the OHSU Oregon National Primate Research Center and the University of Pittsburgh. “These problems can manifest themselves in a number of ways including increased anxiety, anti-social behavior, depression, drug and alcohol abuse and suicide. However, to this date, little information has been obtained as to whether the timing of early life stress exposure can be linked to differing outcomes. In addition, few studies have been conducted to determine the best methods for preventing or counteracting the lifelong impacts of such early life stress exposure.”

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
